Fresh Eyes now on the App Store
A couple of days ago, I introduced Fresh Eyes, a little macOS utility to help me practice the 20-20-20 rule and take better care of my vision while on the computer.
Today, Fresh Eyes was approved and is now available on the macOS App Store.
Fresh Eyes: 20-20-20 for macOS
I've been lucky to have enjoyed healthy vision throughout my life. That is, until recently. Nothing major, I'll need glasses for some activities. I also learned from the optometrist I should follow the 20-20-20 rule to reduce eye strain.
The 20-20-20 rule is simple:
Take a break from looking at your computer screen every 20 minutes and look away at something roughly 20 feet away (6 metres) for 20 seconds.
While there are no shortages of macOS timer apps available, I figured it'd be fun to build a 20-20-20 one anyway.
Meet Fresh Eyes. I've been using it in the last few days. If you'd like to give it a try, send me an email at me@xenodium.com and I'll reply with a TestFlight invite.
If looking for alternatives, Samuel W. Flint offers a couple of great options:
- On Emacs: hammy.el by Adam Porter (alphapapa).
- On Linux/Windows (GTK-based): Workrave by Raymond Penners & Rob Caeler.
Update
Emacs 29.3 emergency release
It was only last week when I upgraded to Emacs 29.2. Yup, I was late to the party. This week, we have a new release.
Emacs 29.3 is an emergency bugfix release, so this time I've upgraded promptly. I'm on macOS using the great Emacs Plus so upgraded via Homebrew using:
brew reinstall emacs-plus@29 --with-imagemagick --with-no-frame-refocus --with-native-comp --with-savchenkovaleriy-big-sur-3d-icon --with-poll
ps. Like this splash screen? Check out the Emacs eye candy post.
Emacs: Toggling the continuation indicator
By default, Emacs typically displays curly arrows when wrapping lines. While likely a handy feature to some, I didn't really find much use for it. At the same time, I never looked into their removal until now.
Turns out, there's a continuation
entry in fringe-indicator-alist
variable that handles this. Removing this entry also removes the curly arrows.
(setq-default fringe-indicator-alist
(delq (assq 'continuation fringe-indicator-alist) fringe-indicator-alist))
Alternatively, one could write a simple function to toggle displaying the continuation indicator.
(defun toggle-continuation-fringe-indicator () (interactive) (setq-default fringe-indicator-alist (if (assq 'continuation fringe-indicator-alist) (delq (assq 'continuation fringe-indicator-alist) fringe-indicator-alist) (cons '(continuation right-curly-arrow left-curly-arrow) fringe-indicator-alist))))
That's it for this post. A tiny tip. Perhaps there's a better way to handle it. If you know, I'd love to know too (Mastodon / Twitter / Reddit / Email).
The Org bundle
I have three apps on the App Store: Plain Org, Flat Habits, and scratch.
Plain Org / plainorg.com
My more generic solution to access org files on the go and away from Emacs.
Flat Habits / flathabits.com
My take on frictionless habit tracking truly respecting user privacy and their time (absolutely no distractions).
*scratch*
/ App Store
Sure, we have tons of note-taking apps but most require more steps than desirable to write something down ASAP. Launch the app and you're good to write. No new note creation, bring keyboard up, etc.
Common denominator
In addition to being offline-first, no cloud, no login, no ads, no tracking, no social… each app targets a specific purpose, sharing an important common denominator: they all use org markup as the underlying storage.
The Org bundle / App Store
While you can still get each of my apps individually, you now have the option to get them all as a single bundle: The Org bundle.
Journelly joining the bundle soon…
Continuing on the org storage theme, I got another app in the works. Also joining The Org bundle, maintaining its privacy-first approach: offline, no cloud, no login, no ads, no tracking, no social… this time in the journaling space.
Journelly is currently in beta, want to join?
sqlite-mode-extras on MELPA
Emacs 29 introduced the handy sqlite-mode. Soon after, I tried a couple of experiments here and there to bring additional functionality.
Folks reached out. The additions seemed useful to them and were keen on upstreaming or pushing to MELPA. While I can't commit to upstreaming at this moment, I can happily meet halfway on MELPA.
As of a couple of days, you can find sqlite-mode-extras on MELPA and GitHub. Contributions totally welcome.
While I haven't heard of issues, please continue treating the package as experimental and exercise safety with your data. Please back up.
Som tam salad dressing recipe (improvised)
Lately, I've been slightly obsessed with Som Tam, a magnificent salad packing both crunch and flavour.
I didn't have all the right ingredients for the full-blown salad at home, so I set out to experiment with the dressing's punchy flavours. While I've gone a little rogue here, I mean no disrespect to the faithful recipe and all its glory. Luckily, I did have fish sauce at home, which I considered the core ingredient, and made do with everything else I could find.
This is where I landed:
- 2 cloves of garlic
- Thai chillies to taste (improvised with chilli flakes)
- 2 tablespoons of fish sauce
- 1 tablespoons of palm sugar (improvised with honey)
- 2 limes squeezed (improvised with lemon)
- 1 tablespoon of dried shrimp (didn't have any)
- 1 small plum tomato (I used 2 of those bite-size ones)
Using my trusty mortar and pestle, I ground and crushed the garlic, chilli flakes, and tomato, forming a paste of sorts. Then added the remaining liquids (fish sauce, honey and lemon) diluting the paste.
- 2 tablespoons of roasted peanuts (roasted some cashews)
Most recipes seem to suggest using peanuts, though my local Thai restaurant uses cashews. Luckily I had cashews at home, so I'm copied my local. Roasted them on pan for a few minutes.
As you can imagine, I didn't just have a green papaya laying around at home, so I experimented with other crunchy veggies. While I won't reveal what the other veggies were (oh man, I've gone way off script), both my other half and I were happy with the results.
Som Tam dressing packs an awesome punch. If your salads were feeling a little boring, give this a try!
My first bread (pane dei Castelli recipe)
I followed The easiest no knead bread recipe (video).
No-knead method
Dough
- 1 1/4 cups (300g) lukewarm water
- 2 teaspoons (8g) salt
- 1 teaspoon (3.5g) yeast
- 3 cups (420g) all purpose flour
Mix thoroughly (I like to use Ciro's spoon mixing method from this video), cover and rest for 6 hours. Stretch and fold if the dough collapsed on itself to rescue.
Bake
- Preheat oven (and dutch oven) at 230°C.
- Flour.
I didn't have a dutch oven, but my oven-proof saucepans (with lid) did just fine. Carefully take the pan out of the oven, sprinkle the bottom with some flour, and place the dough inside. Cover with lid (careful, also hot) and bake for 30-35 minutes.
Crust
- Reduce heat to 200°C.
Remove the lid and bake for another 10 minutes or until you get the crust darkness of your choice.
Rest
Let the bread cool on a cooling rack for 45 mins before cutting. If no rack available, set upsidedown.
Stretch and fold method
Dough
- 1 1/4 cups (300g) lukewarm water
- 2 1/2 teaspoons (10g) salt
- 2 teaspoon (7g) yeast
- 3 cups (420g) all purpose flour
Mix thoroughly (I like to use Ciro's spoon mixing method from this video), cover and rest for 6 hours. Stretch and fold if the dough collapsed on itself to rescue.
Stretch and fold
See Emma Fontanella's stretch and fold technique and apply 4-5 times every 30 mins.
Follow no-knead method
Remaining steps are the same as the no-knead method.
Seafood stew recipe
I've made this seafood stew a handful of times and it's always delivered.
Garlic almond paste
- 1/8 cup of olive oil.
- 8 cloves of garlic chopped.
- 1/4 cup almond meal (flour).
Cook garlic in low-medium heat until softened. Add almond meal and cook 3-4 mins or until golden. Set aside to cool.
- 1 large handful of parsley.
Blend the almond mixture to make a paste. Set aside.
Spices
- 1 large onion halved and sliced.
In a large pan, cook onion until softened.
- 1/8 cup of olive oil.
- 1 large red chilli finely chopped (on occasions, I use chilli flakes).
- 1 teaspoon of smoked paprika.
- 2 bay leaves.
Add chilli, paprika, and bay leaves and cook for 30 seconds (or fragrant).
Liquids
- 1/3 cup dry white wine (I've used cooking sake on occasion).
- 1000g of passata (typically comes in 500g packs).
- 400g plum tomatoes tin (undrained).
- 1 teaspoon of saffron threads (soaked in 2 tablespoons of water).
- 1 tablespoon of tomato paste.
- 2 cups of fish stock (I've used 2 stock cubes + same amount of water).
Add the wine, passata, plum tomatoes, saffron, tomato pate, and fish stock. Simmer for 10 minutes.
Fish
- 700g of firm white fish (cut into 5 cm chunks).
- 12 mussels.
Add the almond paste, fish, and mussels. Cook for 3-4 minutes.
- 12 prawns (shelled).
Add the prawns. Cook for 3 minutes (or pink).
Finishing touches
Season with salt and pepper to taste. I've added roughly a teaspoon of salt.
Garnish generously with parsley and you're good to go.
A Cloudflare Workers primer: hello world
o______________o | Hello world! | o--------------o \ ^__^ \ (oo)_______ (__)\ )\/\ ||----w | || ||
Keen to get started with your Hello World Cloudflare Worker? Skip to the setup section.
A little background
The vast majority of my software development experience has been centered around client-side software. The few times I've needed a server-side component for a hobby project, I've historically provisioned a linux virtual machine somewhere and ran whatever services I needed. I have to admit though, I don't enjoy the provisioning process, configuration, maintenance, upgrades, database admin, etc. which take time away from the part I enjoy more: building and experimenting with features.
While containers have made things somewhat simpler, much of the maintenance tradeoffs remain.
These days, the server-managing overhead has been greatly reduced by "serverless" solutions. Odd terminology for a server offering, but I digress. It more or less refers to removing most of that additional responsibility that comes with managing your own servers and enabling you to focus on building your business logic. Having said that, I've typically shied away from these services, with the possibly irrational fear of vendor lock-in.
The thing is, if most of my potential server-side needs merely require an entry point (where I could route/handle incoming requests) and possibly some persistence (maybe a database), I should be able to abstract these things away and build server-side logic against portable abstractions. With that in place, maybe there's little vendor lock-in to worry about? Who knows, the devil's in the detail. If I keep shying away from these services, I'll never know, so maybe I should try some and see.
Let's try Cloudflare Workers
There are no shortages of serverless options offering functions as a service. Google Cloud, AWS Lambda, Azure Functions, Vercel Functions, Netlify Functions, Fastly, Cloudflare workers, I could go on…
While I haven't researched the different offerings, I had made a mental note to check out Cloudflare Workers as they had announced D1, their database backed by SQLite …and who doesn't love SQLite? ;) OK, I'm no expert here, but I have had a pleasant experience whenever I've used it. These days, even Emacs 29 got some SQLite love, which prompted me to add cell navigation/navigation and try other experiments.
D1 / SQLite in beta
Keep in mind that D1 is in public beta and not yet recommended for large production workloads. From the Cloudflare site:
"While the D1 team expects breaking changes and issues to be minimal, they may still occur. The D1 team generally does not recommend running large production workloads on beta products."
Workers cost
In terms of pricing (as of 2024-01-13), the free tier enables workers to handle up 100,000 requests per day. Plenty for trying things out.
In any case, we're only checking out Cloudflare's offering, so let's move on…
Settings up a new Cloudflare Worker (via web dash)
Cloudflare has a tiny snippet on their Workers landing page that sets things up rather quickly, but I won't be using it.
~/ $ npm create cloudflare -- my-app ~/ $ cd my-app ~/ $ npx wrangler deploy Published https://my-app.world.workers.dev
⚠️ Note: before you get copying and pasting, read on.
Cloudflare's snippet is helpful, but it does quite a bit under the hood. I'm somewhat of a node and serverless noob, so I wanted to understand things a little more and figure out the bare minimum needed to start a minimal Cloudflare Worker project.
Instead, we'll first click here and there over at https://dash.cloudflare.com to spin off our new worker from the web and later continue from the command line.
Give the worker a name. We'll call it "todos" to give ya a little sneak peak at what the next post is possibly about… But you can call it whatever you'd like. Keep in mind you'll need to use this name to refer to your new worker.
Congrats, you've now deployed a new worker. You can access it via the URL that looks something like https://todos.somewhere.workers.dev
This is great and all, but we want to build something with this new worker, so let's set up our local development environment…
Prerequisites
Create a new node project
We want to start with a bare bones node project, so let's do just that.
mkdir HelloCloudflareWorker
cd HelloCloudflareWorker
npm init -y
Install TypeScript (compiler)
I like some guardrails when targetting Javascript, so I'll use the TypeScript compiler in this project. Let's install it.
npm install --save-dev typescript npx tsc --init
Install Cloudflare Typescript types
To have Cloudflare types information accessible to the TypeScript compiler, we'll need to install that too.
npm install --save-dev @cloudflare/workers-types
Install Wrangler (Cloudflare tooling)
To manage your worker from the command-line, you'll need Cloudflare's wrangler tool. Let's install it.
npm install --save-dev wrangler
Point Wrangler to our worker
We're done installing things now. Let's point wrangler to our new worker by creating its config file.
wrangler.toml
name = "todos" main = "worker/worker.ts"
Worker entry point
By default, the worker we created using Cloudflare's dash has the following entry point:
export default { async fetch(request, env, ctx) { return new Response( 'Hello World!'): } }
However, this isn't yet included in our development environment. We need to write our first bit of code. You may have noticed our wrangler.toml
is pointing to the main entry point (worker/worker.ts
) and this file doesn't exist yet. Let's create it, though be sure to also create its owning directory:
mkdir worker
Now we can create our very own worker/worker.ts
. Let's make the first change that shapes worker to our liking. Rather than just printing "Hello World", let's style things up using our cow friend. We'll create worker/worker.ts
and include the spiffed up message.
worker/worker.ts
import { Env, ExecutionContext } from '@cloudflare/workers-types'; export default { async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> { let defaultResponse = ` o______________o | Hello World! | o--------------o \\ ^__^ \\ (oo)\_______ (__)\\ )\\/\\ ||----w | || ||` return new Response(defaultResponse); } };
It's worth mentioning the import statement, since it brings Cloudflare's type information for both Env
and ExecutionContext
.
Running worker locally
Okay, we now have our worker/worker.ts
code ready to go. Let's run it locally. For that we use the wrangler utility.
npx wrangler dev
With that, you'll notice the worker is now running locally and waiting to be visited at http://localhost:8787.
Deploying worker
When we first created the worker via https://dash.cloudflare.com, it automatically deployed to https://todos.somewhere.workers.dev. But our mods only ran locally. Let's deploy, again with the wrangler utility.
npx wrangler deploy
We're good to go. Let's point our browser to the worker's public location.
…and with that, we have a functional Cloudflare Worker and a local development environment to shape things up however we'd like. What would you use the Worker for?
Gave this primer a try? I'd love to hear from ya (Mastodon / Twitter / Reddit / Email).

A chatgpt-shell compose ux experiment
It's been roughly 9 months since I experimented with wiring the ChatGPT API to an Emacs comint buffer in chatgpt-shell. ChatGPT's request-response nature maps fairly well to a shell's mode of interaction.
In the past, I've also talked about blurring the lines between shell and editor. That is, using Emacs as your shell (eshell being my favourite) enables compounding goodies from both shell and editor when both are used from the same app.
Keeping interactions within the same app also cuts down on some of that friction that comes with context switching between your text editor and the browser for llm things.
Today, my interactions with llms typically consists of copying and pasting details from other Emacs buffers, crafting a query, and finally submitting by pressing enter (RET) from a shell like chatgpt-shell.
With the entire interaction happening from Emacs, we're already cutting a fair amount of friction… But we can do better, specially when copying, pasting, and crafting those multi-line queries (you don't want to prematurely submit those shell queries by inadvertently pressing RET when you want a newline).
chatgpt-shell-prompt-compose
This is where chatgpt-shell-prompt-compose
comes in, an opinionated experiment bringing some of my favourite "compose" features over from the likes of magit commit buffers, org capture, mu4e compose, and so on…
You can bring a compose buffer up by invoking M-x chatgpt-shell-prompt-compose
. From there, you can both craft and send your queries. If you're a magit fan, the process should feel fairly familiar with crafting a git commit message by editing away and quickly committing (via C-c C-c
binding). Similarly, you can also abort with the familiar C-c C-k
binding.
I use this compose utility often enough that I bound it to C-c C-e
, though this may not be your cup of tea (needs overriding other mode maps).
(use-package chatgpt-shell :commands (chatgpt-shell chatgpt-shell-prompt-compose) :bind (("C-c C-e" . chatgpt-shell-prompt-compose) :map org-mode-map ("C-c C-e" . chatgpt-shell-prompt-compose) :map eshell-mode-map ("C-c C-e" . chatgpt-shell-prompt-compose) :map mu4e-compose-mode-map ("C-c C-e" . chatgpt-shell-prompt-compose) :map emacs-lisp-mode-map ("C-c C-e" . chatgpt-shell-prompt-compose)))
While the compose buffer displays a single query/response at a time, it also follows on from previous requests. You can press r
to reply and continue the conversation.
The compose buffer is fairly stateless and mostly serves as viewport over the last query in the shell itself. If you invoke chatgpt-shell-prompt-compose
with a prefix (ie. C-u), it wipes the shell history. You can do it from the compose buffer itself, if you forgot to prior to launching.
You can also use the o
binding to jump to the "other buffer" (the shell carrying the conversation history).
If using the r
and o
bindings in a compose buffer sounds a little strange, fear not. The compose buffer is writeable while crafting queries, thus you can safely insert any character. Once a query is submitted (via C-c C-c
), the buffer automatically becomes read-only, and thus unlocking single-character bindings.
Another magit commit favorite of mine is using the M-p
or M-n
bindings to insert previous messages via git-commit-prev-message
or git-commit-next-message
.
With that in mind, I also brought M-p
and M-n
over to the editable compose buffer.
If cycling isn't efficient enough, you can also use the typical M-r
binding to search and insert from history.
Now, getting back to removing some of that copy-pasting friction… Selecting text in any buffer and invoking M-x chatgpt-shell-prompt-compose
(or C-c C-e
in my case) automatically pastes the region into the compose buffer. You get to tweak your query before submitting (via that familiar C-c C-c
), in a more flexible buffer (compared to a shell).
Note: You can also invoke the compose command with a region as many times as you'd like. Each region is sent to the compose buffer, so you can craft more involved queries before submission.
While I typically prefer short query responses (using diffs like the example above), I sometimes want full snippets as follow-ups. I found myself typing "show entire snippet" often enough, that I now use one of those single-character bindings (e
) for this purpose.
Compose bindings
I've showcased most of the compose key bindings, here's the whole lot (so far anyway), which you can also view from chatgpt-shell-prompt-compose
's documentation.
Editing
C-c C-c
to send the buffer query.C-c C-k
to cancel compose buffer.M-r
search through history.M-p
cycle through previous item in history.M-n
cycle through next item in history.
Read-only
C-c C-c
After sending offers to abort query in-progress.q
Exits the read-only buffer.g
Refresh (re-send the query). Useful to retry on disconnects.n
Jump to next source block.p
Jump to next previous block.r
Reply to follow-up with additional questions.e
Send "Show entire snippet" query.o
Jump to other buffer (ie. the shell itself).C-M-h
Mark block at point.
Buyer beware: it's all pretty experimental
When I started playing with the compose buffer idea, I wasn't too sure whether or not its usage would stick, so I basically hacked chatgpt-shell-prompt-compose
to pieces. A cheap prototype of sorts to validate the idea before fully committing to a more involved solution.
I'll eventually rewrite chatgpt-shell-prompt-compose
as either a major or minor mode if there's enough interest.
For now, I'll continue using as is to validate its usefulness.
If you give chatgpt-shell-prompt-compose
a try, I'd love to hear your feedback (Mastodon / Twitter / Reddit / Email).

A Murder at the End of the World: Are you Vi or Emacs?
I've enjoyed watching A Murder at the End of the World. The show may resonate with folks following the tech world. Won't say much more than that…
What I can maybe say is, the shows features Reddit, Brave browser, terminal usage (ifconfig, nmap, hydra, responder), and a reference to the good 'ol Vi vs Emacs rivalry, which I hope folks these days don't take further than friendly teasing between dear cousins.
In any case, being an Emacs nut, the scene gave me a good tickle. It's a great show, with a lovely Emacs cherry on top! While the show title and description didn't immediately draw me in, I'm glad I gave it a chance.
An basic Mullvad WireGuard setup for macOS
Needed a VPN to test an API from a different location. Gave Mullvad a try.
Pretty neat, you can generate an account number without providing an email address. You can also pre-pay with a ton of options, including cash, crypto, credit cards, PayPal, wire transfers…
After seeing your account credited, one can download a generated WireGuard configuration. Also a WireGuard noob, so took this opportunity to give it a try.
The WireGuard macOS app has an "Import Tunnel(s) from File…" option where you can import the .conf file downloaded from Mullvad's generated config. After that, all I had to do was click the "Activate" button and Bob's your uncle.
You can test your connection via:
curl https://am.i.mullvad.net/connected
You are connected to Mullvad (server xxxxxx). Your IP address is xxx.xxx.xxx.xxx
I had a brief stint at using the command-line alternative via homebrew brew install wireguard-go wireguard-tools

An iOS journaling app powered by org plain text
I've been experimenting with building a rich text editing component for iOS, powered by org markup. The idea is to offer a mobile-friendly editing experience, backed by our beloved plain text format.
To make things a little more interesting, I'm introducing a new org-based app to help anyone with regular journaling.
Plain text is the serialization format. No conversion/import/export needed.
Though it's early days, it's fairly functional. Been using it daily for some time. You can opt in to use an external org file and sync with your beloved Emacs.
Want to give it a try? Want a TestFlight invite? Send me an email address (any would do) at either of these: Mastodon / Twitter / Reddit / Email.
The topic of org being fairly Emacs-oriented, though a strength for someone far down the rabbit hole, it is understandable to call it out for someone in a different position. Lucky for us, org markup is plain text and can be implemented by apps other than Emacs, like Journelly itself for iOS and even more experimentally on macOS:
And like Journelly for iOS, I got other org things available on iOS:
As an Org mode fan, so I wrote Plain Org for iOS. It's on the App Store. | |
Inspired by Atomic Habits, I wrote Flat Habits for iOS. Also on the App Store. | |
I needed an Emacs-inspired scratch buffer on iOS (who doesn't?), so I built one. |

Building your own bookmark launcher
✨sponsor✨ this content
I've been toying with the idea of managing browser bookmarks from you know where. Maybe dump a bunch of links into an org file and use that as a quick and dirty bookmark manager. We'll start with a flat list plus fuzzy searching and see how far that gets us.
The org file would look a little something like this:
My bookmarks - [[https://lobste.rs/t/emacs][Emacs editor (Lobsters)]] - [[https://emacs.stackexchange.com][Emacs Stack Exchange]] - [[https://www.reddit.com/r/emacs][Emacs subreddit]] - [[https://emacs.ch][Emacs.ch (Mastodon)]] - [[https://www.emacswiki.org][EmacsWiki]] - [[https://planet.emacslife.com/][Planet Emacslife]]
Next we need fuzzy searching, but first let's write a little elisp to extract all links from the org file:
(require 'org-element) (require 'seq) (defun browser-bookmarks (org-file) "Return all links from ORG-FILE." (with-temp-buffer (let (links) (insert-file-contents org-file) (org-mode) (org-element-map (org-element-parse-buffer) 'link (lambda (link) (let* ((raw-link (org-element-property :raw-link link)) (content (org-element-contents link)) (title (substring-no-properties (or (seq-first content) raw-link)))) (push (concat title "\n" (propertize raw-link 'face 'whitespace-space) "\n") links))) nil nil 'link) (seq-sort 'string-greaterp links))))
The snippet uses org-element
to iterate over links to collect/return them in a list. We join both the title and url, so searching can match either of these values. We also add a little formatting (new lines/face) to spiff things up.
(browser-bookmarks "/private/tmp/bookmarks.org")
(#("Planet Emacslife\nhttps://planet.emacslife.com/\n" 17 46 (face whitespace-space)) #("EmacsWiki\nhttps://www.emacswiki.org\n" 10 35 (face whitespace-space)) #("Emacs.ch (Mastodon)\nhttps://emacs.ch\n" 20 36 (face whitespace-space)) #("Emacs (Stack Exchange)\nhttps://emacs.stackexchange.com\n" 23 54 (face whitespace-space)) #("Emacs (Reddit)\nhttps://www.reddit.com/r/emacs\n" 15 45 (face whitespace-space)) #("Emacs (Lobsters)\nhttps://lobste.rs/t/emacs\n" 17 42 (face whitespace-space)))
We can now feed our list to our preferred narrowing framework (ivy, helm, ido, vertico) and use it to quickly select a bookmark. In the past, I've used the likes of ivy-read directly, though have since adopted the humble but mighty completing-read
which hooks up to any of the above frameworks.
With that in mind, let's use completing-read
to make a selection and split the text to extract the corresponding URL. Feed it to browse-url
, and you got your preferred browser opening your bookmark.
(defun open-bookmark () (interactive) (browse-url (seq-elt (split-string (completing-read "Open: " (browser-bookmarks "/private/tmp/bookmarks.org")) "\n") 1)))
I remain a happy ivy user, so we can see its fuzzy searching in action.
At this point, we now have our bookmark-launching Emacs utility. It's only an M-x open-bookmark
command away, but we want to make it accessible from anywhere in our operating system, in my case macOS.
Let's enable launching from the command line, though before we do that, let's craft a dedicated frame for this purpose.
(defmacro present (&rest body) "Create a buffer with BUFFER-NAME and eval BODY in a basic frame." (declare (indent 1) (debug t)) `(let* ((buffer (get-buffer-create (generate-new-buffer-name "*present*"))) (frame (make-frame '((auto-raise . t) (font . "Menlo 15") (top . 200) (height . 20) (width . 110) (internal-border-width . 20) (left . 0.33) (left-fringe . 0) (line-spacing . 3) (menu-bar-lines . 0) (minibuffer . only) (right-fringe . 0) (tool-bar-lines . 0) (undecorated . t) (unsplittable . t) (vertical-scroll-bars . nil))))) (set-face-attribute 'ivy-current-match frame :background "#2a2a2a" :foreground 'unspecified) (select-frame frame) (select-frame-set-input-focus frame) (with-current-buffer buffer (condition-case nil (unwind-protect ,@body (delete-frame frame) (kill-buffer buffer)) (quit (delete-frame frame) (kill-buffer buffer))))))
Most of the snippet styles our new frame and invokes the body parameter. While I don't typically resort to macros, we get a little syntatic sugar here, so we can invoke like so:
(defun present-open-bookmark-frame () (present (browse-url (seq-elt (split-string (completing-read "Open: " (browser-bookmarks "/private/tmp/bookmarks.org")) "\n") 1))))
Wrapping our one-liner with the present-open-bookmark-frame
function enables us to easily invoke from the command line, with something like
emacsclient -ne "(present-open-bookmark-frame)"
Now that we can easily invoke from the command line, we have the flexibility to summon from anywhere. We can even bind to a key shortcut, available anywhere (not just Emacs). I typically do this via Hammerspoon, with some helpers, though there are likely simpler options out there.
function emacsExecute(activate, elisp) if activate then activateFirstOf({ { bundleID="org.gnu.Emacs", name="Emacs" } }) end local socket, found = emacsSocketPath() if not found then hs.alert.show("Could not get emacs socket path") return "", false end local output,success = hs.execute("/opt/homebrew/bin/emacsclient -ne \""..elisp.."\" -s "..socket) if not success then hs.alert.show("Emacs did not execute: "..elisp) return "", false end return output, success end function openBookmark() appRequestingEmacs = hs.application.frontmostApplication() emacsExecute(false, "(present-open-bookmark-frame)") activateFirstOf({ { bundleID="org.gnu.Emacs", name="Emacs" } }) end hs.hotkey.bind({"alt"}, "W", openBookmark)
With that, we have our Emacs-powered bookmark launcher, available from anywhere.
While we used our Emacs frame presenter to summon our universal bookmark launcher, we can likely the same mechanism for other purposes. Maybe a clipboard (kill ring) manager?

Native Emacs/macOS UX integrations via Swift modules
Once you learn a little elisp, Emacs becomes this hyper malleable editor/platform. A live playground of sorts, where almost everything is up for grabs at runtime. Throw some elisp at it, and you can customize or extend almost anything to your heart's content. I say almost, as there's a comparatively small native core, that would typically require recompiling if you wanted to make further (native) mods. But that isn't entirely true. Emacs 25 enabled us to further extend things by loading native dynamic modules, back in 2016.
Most of my Emacs-bending adventures have been powered by elisp, primarily on macOS. I also happen to have an iOS dev background, so when Valeriy Savchenko announced his project bringing Emacs dynamic modules powered by Swift, I added it to my never-ending list of things to try out.
Fast-forward to a year later, and Roife's introduction to emt finally gave me that much-needed nudge to give emacs-swift-module a try. While I wish I had done it earlier, I also wish emacs-swift-module had gotten more visibility. Native extensions written in Swift can open up some some neat integrations using native macOS UX/APIs.
While I'm new to Savchenko's emacs-swift-module, the project has wonderful documentation. It quickly got me on my way to build an experimental dynamic module introducing a native context menu for sharing files from my beloved editor.
Most of the elisp/native bridging magic happens with fairly little Swift code:
try env.defun( "macos-module--share", with: """ Share files in ARG1. ARG1 must be a vector (not a list) of file paths. """ ) { (env: Environment, files: [String]) in let urls = files.map { URL(fileURLWithPath: $0) } let picker = NSSharingServicePicker(items: urls) guard let view = NSApp.mainWindow?.contentView else { return } let x = try env.funcall("macos--emacs-point-x") as Int let y = try env.funcall("macos--emacs-point-y") as Int let rect = NSRect( x: x + 15, y: Int(view.bounds.height) - y + 15, width: 1, height: 1 ) picker.show(relativeTo: rect, of: view, preferredEdge: .maxY) }
This produced an elisp macos-module--share
function I could easily access from elisp like so:
(defun macos-share () "Share file(s) with other macOS apps. If visiting a buffer with associated file, share it. While in `dired', any selected files, share those. If region is active, share files in region. Otherwise share file at point." (interactive) (macos-module--share (vconcat (macos--files-dwim))))
On a side note, (macos--files-dwim)
chooses files depending on context. That is, do what I mean (DWIM) style. If there's a file associated with current buffer, share it. When in dired (the directory editor, aka file manager), look at region, selected files, or default to file at point.
(defun macos--files-dwim () "Return buffer file (if available) or marked/region files for a `dired' buffer." (if (buffer-file-name) (list (buffer-file-name)) (or (macos--dired-paths-in-region) (dired-get-marked-files)))) (defun macos--dired-paths-in-region () "If `dired' buffer, return region files. nil otherwise." (when (and (equal major-mode 'dired-mode) (use-region-p)) (let ((start (region-beginning)) (end (region-end)) (paths)) (save-excursion (save-restriction (goto-char start) (while (< (point) end) ;; Skip non-file lines. (while (and (< (point) end) (dired-between-files)) (forward-line 1)) (when (dired-get-filename nil t) (setq paths (append paths (list (dired-get-filename nil t))))) (forward-line 1)))) paths)))
I got one more example of a native macOS integration I added. Being an even simpler one, and in hindsight, I prolly should have introduced it first. In any case, this one reveals dired files in macOS's Finder app (including the selection itself).
try env.defun( "macos-module--reveal-in-finder", with: """ Reveal (and select) files in ARG1 in macOS Finder. ARG1 mus be a vector (not a list) of file paths. """ ) { (env: Environment, files: [String]) in NSWorkspace.shared.activateFileViewerSelecting(files.map { URL(fileURLWithPath: $0) }) }
The corresponding elisp is nearly identical to its macos-share
sibling:
(defun macos-reveal-in-finder () "Reveal file(s) in macOS Finder. If visiting a buffer with associated file, reveal it. While in `dired', any selected files, reveal those. If region is active, reveal files in region. Otherwise reveal file at point." (interactive) (macos-module--reveal-in-finder (vconcat (macos--files-dwim))))
My Swift module experiment introduces two native macOS UX integrations, now available via M-x macos-share
and M-x macos-reveal-in-finder
. I've pushed all code to it's own repo.
I hope this post brings visibility to the wonderful emacs-swift-module project and sparks new, native, and innovative integrations for those on macOS. Can't wait to see what others can do with it.

Migrating/re-encrypting pass's password store
Note to self, I needed to migrate/re-encrypt someone's password store (aka pass). Straightforward:
Get the new key, probably already in gpg key chain. Try listing it:
gpg --list-keys
To re-encrypt, pass init
with new key is enough. It'll prompt for old pass key.
cd path/to/.password-store
pass init NEW-GPG-KEY
How I smash burgers
I'm neither a burger expert nor a connoisseur of any kind, yet I sure have a lot of fun smashing burgers at home. Needless to say, I shamelessly enjoy gobbling them too!
Figure 1: my smash burger
I'll share details on how I smash my burgers, but here's a quick ingredient list, if that's all you need.
- Mince beef (20%-30% fat).
- Streaky bacon.
- Brioche burger buns.
- American cheese slices (cheddar individual slices work too).
- Lettuce.
- Tomatoes.
- Onions.
- Pickles.
- Jalapeños.
- Garlic.
- Chipotle powder.
- Mayonnaise.
- Salt.
- Pepper.
- Oil.
- Greaseproof paper.
- Butter.
The calling
My quest to smash burgers at home didn't start until earlier this year, while watching the The Menu. I just could't stop craving the burger from that scene, so I set out to start smashing my own.
The gear
Don't rush to buy anything fancy. Your existing gear will likely do the job just fine. I'd say try a few things out and only upgrade when needed. I'll share the gear I use and where I felt I needed tweaking.
Skillet
While I didn't have a griddle at home, I did have a couple of trusty Lodge skillets (cast iron and carbon steel). Both work great for burgers, though I have a slight preference for the carbon steel one, as it's the bigger of the two and gives a little more room for manoeuvring, specially when smashing two burgers at a time.
Heat the skillet up and add a little oil. If the oil starts smoking, be quick to drop the patties and start smashing.
Grill Spatula (too big/stiff for skillet)
Somewhat inspired by the film, I got myself a wide spatula so I could firmly press those patties against the skillet, and to flip of course.
While this kind of spatula may work well on a spacious griddle, I felt constrained on a relatively small cast iron. Specially when flipping. I went looking for an alternative.
Spatula + smasher (my winning combo)
Over at the r/castiron subreddit, I discovered fish spatulas. They are fairly agile on cast irons but also work great for loosening burger patties before flipping.
While effective for flipping, fish spatulas are obviously no good for smashing. So I got myself a burger smasher. This combo worked well for me.
When smashing, use greaseproof paper to prevent the patties from sticking to the smasher.
Ingredients
While I've drawn inspiration from others, I've landed on my own preferred ingredients. I'm sure that will continue changing over time. Pick and choose as your heart desires.
Minced/ground beef
Minced beef with higher fat content (around 20-30%) is often recommended for a couple of reasons:
- Flavour: Fat equals flavour in cooking. The higher fat content will melt during cooking and become 'self-basting', resulting in a juicier and more flavourful burger.
- Texture: The fat in the beef melts under heat, helping the burger achieve a crispy, caramelized exterior known as the Maillard reaction, which contrasts nicely against the soft, juicy interior.
In the UK, I can typically find minced beef with 15%-20% fat content at the main supermarkets.
Be sure to salt and pepper to taste (as in picture) on one side. Once flipped on pan, salt and pepper the other side.
Bacon
I tend to prefer smoked streaky bacon, but hey these will be your burgers. Your burgers, your rules.
Buns (brioche)
I hear potato buns are great for burgers. I've yet to try them. So far, I've settled for brioche. I happen to find these near me, so I've gone with them.
Butter the buns and brown on the skillet for a minute. Check the buns often. Brioche buns can burn quickly.
American cheese
American cheese is often the burger cheese of choice.
While American cheese isn't widely available in the UK, the individually wrapped orange-looking cheddar cheese slices work just fine.
Toppings
I like my burgers with lettuce, tomatoes, onions, pickles, and occasionally jalapeños. For pickles, I typically just take cornichons and slice them up.
Burger sauce (chipotle/garlic/mayo)
While classic burger sauce is often made with mayo, ketchup, pickles, and mustard, I've gone fairly rogue here.
You see, I love chipotle mayo. I'm also a fan of garlic mayo, so I figured why not both? Turns out these three ingredients work great together.
I like to draw out the flavours by first mixing the garlic and chipotle with a little hot water.
- 1 garlic clove.
- 2 teaspoons of chipotle powder.
- 1 tablespoon of hot water.
- Pinch of salt.
…and then thicken with mayo.
- 1/4 cup of mayo.
These are very rough measurements, tweak to your preference. Make more garlicky, spicier, or soften things by adding garlic, chipotle, or mayo.
Assembling
I like to assemble in the following order from the bottom bun up.
- Sauce on bottom bun.
- Lettuce.
- Tomatoes.
- Onions.
- 2 patties (melted cheese on both).
- Bacon.
- Pickles.
- Jalapeños.
- Sauce on top bun (oops, I forgot in the picture).
…and here's the final product.
If you gave smashing burgers a go, I'd love to hear about it. Also any tips are very much welcome. Get in touch (Mastodon / Twitter / Reddit / Email).
Open in Xcode at line number
I live mostly in Emacs. I say mostly 'cause well, I'm fairly pragmatic about it. If there's a workflow elsewhere that's more appropriate for my needs, I'll happily use that instead. While I'd love to do my web browsing from my beloved editor, Firefox ticks the right boxes for me.
I do most of my iOS coding in Emacs. It's a hybrid of sorts between Emacs and Xcode. If I need to use the debugger, Xcode is a clear winner for me. If I happen to be visiting a Swift file in an Emacs buffer, I typically used the handy crux-open-with
from crux to open in Xcode, and continue from there. This worked OK, but I always wished opening in Xcode would also jump to the same line number as the Emacs point (cursor) location. This is particularly useful if I had just spotted where I'd like to set a breakpoint in an Emacs buffer and need to transition over to Xcode.
It turns out, there's a nifty command line utility for that. xed, the Xcode text editor invocation tool. It enables telling Xcode what file to open and at what line number:
xed -line 141 path/to/some/file.swift
With that in mind, I've added my own version of crux-open-with
, using dwim-shell-command.
When running on macOS, the function checks whether or not I'm visiting a buffer for a programming language, and opens the file in Xcode at the same line number.
(defun dwim-shell-commands-open-externally () "Open file(s) externally." (interactive) (dwim-shell-command-on-marked-files "Open externally" (if (eq system-type 'darwin) (if (derived-mode-p 'prog-mode) (format "xed --line %d '<<f>>'" (line-number-at-pos (point))) "open '<<f>>'") "xdg-open '<<f>>'") :shell-args '("-x" "-c") :silent-success t :utils (if (eq system-type 'darwin) "open" "xdg-open")))
dwim-shell-commands-open-externally
is now added to dwim-shell-commands.el.
ps. If you find opening the same file in a different context handy, you may also like the package browse-at-remote that opens the visited file at its corresponding remote location (for example, GitHub). I can never remember the name of the function (browse-at-remote), so I aliased it to something I'd remember and moved on…
(defalias 'ar/open-at-github #'browse-at-remote))
Trimming video screenshots
A quick one… I recently wanted to trim the black borders around a video screenshot. While I could use an image editor to manually select and trim, I wondered if there was an imagemagick trick somewhere out there for such a thing… and of course there was:
magick convert -fuzz 3% -define trim:percent-background=0% -trim +repage path/to/input.png path/to/output.png
Pretty neat. It does the job, but I won't remember it next time. May as well make another dwim-shell-command function out of it and conveniently invoke from Emacs via a memorable name plus fuzzy search.
(defun dwim-shell-commands-image-trim-borders () "Trim image(s) border (useful for video screenshots)." (interactive) (dwim-shell-command-on-marked-files "Trim image border" "magick convert -fuzz 3% -define trim:percent-background=0% -trim +repage '<<f>>' '<<fne>>_trimmed.<<e>>'" :utils "magick"))
While the screenshot I've just used was a little blurry, it's from the movie Tron Legacy, and it features Emacs eshell. This is old news, though well covered.
dwim-shell-commands-image-trim-borders
is now added to dwim-shell-commands.el
Displaying image details in mode line
A benefit of running Emacs as a GUI app, is that you can view images from your beloved editor. This is super handy to take a quick peek at any image.
Sometimes, I'd like a little more than just viewing the image. I'd like to see basic image details like type, dimensions, and file size. The imagemagick identify
utility is pretty handy for that.
identify -format "%m %wx%h %b" path/to/image.png
PNG 2387x1055 2.28454MB
I could easily invoke shell-command
for this or even create a dwim-shell-command function (maybe I will), but if this info was proactively displayed in the mode line, I wouldn't have to fetch it myself.
Since I know I can use the identify
command for this, I may as well see if I can plug it into the mode line.
Turns out this wasn't too bad by setting setting mode-line-format
. I added a little logic to only include image details while in image-mode
and rely on process-lines
to fetch the details. This function returns a list, which is a happy coincidence since mode-line-format
also expects a list.
(setq-default mode-line-format '(" " mode-line-front-space mode-line-client mode-line-frame-identification mode-line-buffer-identification (:eval (when (eq major-mode 'image-mode) ;; Needs imagemagick installed. (process-lines "identify" "-format" "[%m %wx%h %b]" (buffer-file-name)))) " " mode-line-position (vc-mode vc-mode) (multiple-cursors-mode mc/mode-line) " " mode-line-modes mode-line-end-spaces))
I'd love to hear if there's a pure elisp alternative (mastodon/twitter). I gave (image-size (image-get-display-property) :pixels)
a try, but that seemed to return the display size in buffer rather than actual file size.
Creating an iCloud account (via tart VM)
UPDATE: This method no longer works for creating iCloud accounts. I'd love to know if you find an alternative. Please let me know.
I wanted an additional @icloud.com account for myself. My first thought was to head over to https://developer.apple.com and create a new account, but that requires an existing email address. I wanted an actual @icloud.com email address.
My next thought was to create a new account using the iOS simulator, but that complained about creating too many accounts already. Strange, as I hadn't created any.
I could create an account from macOS settings itself, though that would require logging out my current account (and the syncing implications). To get around that, I could maybe create a temporary macOS user. Instead, I somewhat revisited the simulator route and looked for a VM option to run macOS. This gave me an excuse to play with VM options on macOS.
I had been meaning to check out lima as per Hacker News's Lima: A nice way to run Linux VMs on Mac. The Hacker News's thread has a handful of great recommendations. Amongst them, tart (macOS and Linux VMs on Apple Silicon) stood out, as it also gave me the Mac on Mac option.
Installing tart
via Homebrew followed the typical brew
command… a breeze via my trusty Emacs eshell:
brew install cirruslabs/cli/tart
Cloning a VM image, while straightforward, it did take a little while for the chunky download:
tart clone ghcr.io/cirruslabs/macos-sonoma-base:latest sonoma-base
Running the macOS Sonoma VM was a breeze:
tart run sonoma-base
…and with that, I got a full (and disposable) macOS VM I can use to create another @icloud.com account:
While there may be simpler options out there to create an @icloud.com account (please do let me know mastodon/twitter), the VM did the job. I'd been meaning to find a low friction mechanism to run VMs for a different reason, but that's a post for another time.

Emacs hangs saving .authinfo.gpg (workaround)
My Emacs (v29.1) was hanging when saving changes to .authinfo.gpg. Turns out, I ran into a known issue with a workaround. Downgrading gnupgp to a version older than 2.4.1 sorts things out.
I'm on macOS. Downgraded by downloading the 2.4.0 Homebrew formula at https://raw.githubusercontent.com/Homebrew/homebrew-core/59edfe598541186430d49cc34f42671e849e2fc9/Formula/gnupg.rb and installing with:
brew unlink gnupg brew install ~/Downloads/gnupg.rb
Redact that buffer
As I was getting ready to take an Emacs screenshot in the previous post, I figured I may want to redact email addresses before moving forward. I had a quick look for existing options and found redacted.el, built-in toggle-rot13-mode
, and unpackaged/lorem-ipsum-overlay. All great options. I wanted a solution I could feed a single regular expression to obscure matches. I also wanted toggling capabilities, so I had a quick go at it…
I also wanted the ability to redact the entire buffer content, so feeding a space to the regexp query also translates to [[:graph:]]
, effectively redacting all visible characters.
The solution is overlay-based, ensuring the buffer content remains unchanged. The function may have its own rough edges, yet it certainly scratched the itch for the current need. I'll leave ya with the snippet.
(defun ar/toggle-redact-buffer () "Redact buffer content matching regexp. A space redacts all." (interactive) (let* ((redacted) (regexp (string-trim (read-regexp "Redact regexp" 'regexp-history-last))) (matches (let ((results '())) (when (string-empty-p regexp) (setq regexp "[[:graph:]]") (setq regexp-history-last regexp) (add-to-history 'regexp-history regexp)) (save-excursion (goto-char (point-min)) (while (re-search-forward regexp nil t) (push (cons (match-beginning 0) (match-end 0)) results))) (nreverse results)))) (mapc (lambda (match) (dolist (overlay (overlays-in (car match) (cdr match))) (setq redacted t) (delete-overlay overlay)) (unless redacted (overlay-put (make-overlay (car match) (cdr match)) 'display (make-string (- (cdr match) (car match)) ?x)))) matches)))
Send note to Kindle
While on Mastodon, I spotted @summeremacs looking into sending Emacs text selections to a Kindle via email. This sparked my interest as I previously looked into sending pdfs to my Kindle via mu4e.
Kindle offers a neat service where you can email a file to your @kindle.com
address and it automatically shows up in your Kindle library.
I already do email from my beloved editor, and like most Emacs things, it's powered by elisp. In other words, it's basically up for grabs if you'd like to glue it to anything else, so I did…
I can now select a region and invoke M-x send-to-kindle-as-txt
to send it over to my Kindle.
Soon enough, the note shows up on my Kindle.
Opening the note reveals the same content we had previously selected and sent from our malleable editor.
While it looks kinda magical, it's fairly simple under the hood. It takes the region content, writes it to a txt file, creates an email message buffer attaching the file, and finally sends via message-send-and-exit
.
If M-x send-to-kindle-as-txt
is invoked with a C-u
prefix, you get to inspect the message buffer right before sending via C-c C-c
.
Here's the full snippet.
(defcustom send-to-kindle-from-email nil "Your own email address to send from via mu4e." :type 'string :group 'send-to-kindle) (defcustom send-to-kindle-to-email nil "Your Kindle email address to send pdf to." :type 'string :group 'send-to-kindle) (defun send-to-kindle-as-txt (review) (interactive "P") (unless send-to-kindle-from-email (setq send-to-kindle-from-email (read-string "From email address: "))) (unless send-to-kindle-to-email (setq send-to-kindle-to-email (read-string "To email address: "))) (let* ((content (string-trim (if (region-active-p) (buffer-substring (region-beginning) (region-end)) (buffer-string)))) (note-name (let ((name (string-trim (read-string "Note name: ")))) (if (string-empty-p name) (nth 0 (string-split (substring content 0 (min 40 (length content))) "\n")) name))) (path (concat (temporary-file-directory) note-name)) (txt (concat path ".txt")) (buffer (get-buffer-create (generate-new-buffer-name "*Email txt*")))) (with-temp-buffer (insert content) (write-file txt)) (with-current-buffer buffer (erase-buffer) ;; Disable hooks (let ((message-mode-hook nil)) (message-mode)) (insert (format "From: %s To: %s Subject: %s --text follows this line-- <#multipart type=mixed> <#part type=\"text/plain\" filename=\"%s\" disposition=attachment> <#/part> <#/multipart>" send-to-kindle-from-email send-to-kindle-to-email note-name txt)) (unless review (message-send-and-exit))) (when review (switch-to-buffer buffer))))
By the way, and I only just learned this today… To take a screenshot on a Kindle Paperwhite, tap on these opposite corners.
SHA-256 hash from URL, the easy way
From time to time, I need to generate a SHA-256 hash from a file hosted on some server. For me, this flow typically goes something along the lines of:
- Copy the file URL from browser.
- Drop to Emacs eshell.
- Change current directory.
- Type "curl -o file"
- Paste the file URL.
- Run curl command.
- Type "shasum -a 256 file".
- Run shasum command.
- Copy the generated hash.
- Maybe delete the downloaded file?
We can maybe shave some steps off by downloading directly from the browser, though that may also bring additional clicks and navigating to a download location.
Amongst the steps, shasum is the star player, and its output can be seen below.
shasum -a 256 path/to/downloaded/file
3da351027e5b1495c7c7fe4abbf8d7ac9625da3604be5a35c9a9cbb92f6f955a path/to/downloaded/file
Not a huge deal. One can copy the hash from the output, but why go through multiple small manual steps when I know I can get Emacs to simplify the lot? I've expedited a similar flow in the past when cloning git repos. Let's simplify again so hashing a hosted file boils down to:
- Copy the file URL from browser.
- Run an Emacs interactive command.
This is where I pull out dwim-shell-command (a little package I wrote) and glue the lot to get an expedited experience.
There isn't much to the function other than glueing a little elisp and a shell script via dwim-shell-command
for some buffer/error handling.
(defun dwim-shell-commands-sha-256-hash-file-at-clipboard-url () "Download file at clipboard URL and generate SHA-256 hash." (interactive) (let ((url (current-kill 0))) (unless (string-match-p "^http[s]?://" url) (user-error "No URL in clipboard")) (dwim-shell-command-on-marked-files "Generate SHA-256 hash from clipboard URL." (format "temp_file=$(mktemp) function cleanup { rm -f $temp_file } trap cleanup EXIT curl --no-progress-meter --location --fail --output $temp_file %s || exit 1 shasum -a 256 $temp_file | awk '{print $1}'" (shell-quote-argument url)) :utils '("curl" "shasum") :on-completion (lambda (buffer process) (if-let ((success (= (process-exit-status process) 0)) (hash (with-current-buffer buffer (string-trim (buffer-string))))) (progn (kill-buffer buffer) (kill-new hash) (message "Copied %s to clipboard" (propertize hash 'face 'font-lock-string-face))) (switch-to-buffer buffer))))))
dwim-shell-commands-sha-256-hash-file-at-clipboard-url
is now in dwim-shell-commands.el, the optional counterpart in dwim-shell-command.
UPDATE
There's better way. Thanks to Philip Kaludercic for suggesting curl -s example.com | sha256sum - | cut -d " " -f1
and Sacha Chua who pinged me about it.
Also note I'm now relying on the <<cb>>

Inline previous result and why you should edebug
Artur Malabarba's Debugging Elisp Part 1: Earn your independence is nearly a decade old, yet it rings just as true today.
Learning to Edebug really "is the right decision for anyone who doesn't know how to Edebug." Why, you may ask? He best puts it as "running into errors is not only a consequence of tinkering with your editor, it is the only road to graduating in Emacs."
For me personally, it earned me that independence to bend Emacs my way. Don't like how something works? Pull up the debugger to help me understand how a package or function works. I've done this countless of times to bend things my way.
Speaking of edebug, I had been meaning to tweak edebug's result display behaviour for quite some time. As you step through code, edbug prints the result of previous expressions to the minibuffer. This works well, but I couldn't help but feel like my eyes were constantly jumping between the code and the minibuffer at the bottom of the window.
I wanted to minimize the eye jumping experience, so I figured I could likely bend things my way and print the result at point. How did I go about it? The same way I often do. Figure out what function is called for a given key binding via describe-key or my favourite replacement helpful-key from helpful.el. This led me to edebug-next-mode
in edebug.el
. At that point, I could have set a breakpoint in edebug-next-mode
and eventually step into the relevant code, but hey we had a better clue. We knew that all output started with "Result:", so we could just search for that string in edebug.el
instead. Jackpot! edebug-compute-previous-result
and its adjacent edebug-previous-result
are just the right functions:
(defun edebug-compute-previous-result (previous-value) (if edebug-unwrap-results (setq previous-value (edebug-unwrap* previous-value))) (setq edebug-previous-result (concat "Result: " (edebug-safe-prin1-to-string previous-value) (eval-expression-print-format previous-value)))) (defun edebug-previous-result () "Print the previous result." (interactive) (message "%s" edebug-previous-result))
We can see that edebug-previous-result
invokes message
which is responsible for displaying the debugged expression's result in the minibuffer. Modifying this functions behaviour would be enough to achieve inline display, but I also want to remove "Result:" from the displayed message. Neither of these functions offer configurability, so we'll resort to advising both functions. That is, monkey patch them (errm I know… lovely).
(defun adviced:edebug-compute-previous-result (_ &rest r) "Adviced `edebug-compute-previous-result'." (let ((previous-value (nth 0 r))) (if edebug-unwrap-results (setq previous-value (edebug-unwrap* previous-value))) (setq edebug-previous-result (edebug-safe-prin1-to-string previous-value)))) (advice-add #'edebug-compute-previous-result :around #'adviced:edebug-compute-previous-result)
adviced:edebug-compute-previous-result
removes "Result:" in addition to dropping (eval-expression-print-format previous-value)
, which I don't typically rely on.
(require 'eros) (defun adviced:edebug-previous-result (_ &rest r) "Adviced `edebug-previous-result'." (eros--make-result-overlay edebug-previous-result :where (point) :duration eros-eval-result-duration)) (advice-add #'edebug-previous-result :around #'adviced:edebug-previous-result)
adviced:edebug-previous-result
is in charge of display via message
, so all we need is some replacement. I initially played with popup-tip and that did the job just fine, but Colin led me to a better path while pointing to Clojure and Common Lisp. This reminded me of eros: Evaluation Result OverlayS for Emacs Lisp, which I already used. Swapping message
for eros--make-result-overlay
did the trick. Yes, this is a private function, but I can live with that. This code is only an advice-remove
away from disabling, but hey look at those inline results!
Further sqlite-mode extensions
I've continued poking at Emacs 29's sqlite-mode. Since my last post on extensions, I've experimented a little with adding a handful of interactive functions:
sqlite-mode-extras-compose-and-execute
: Compose and execute a query.
sqlite-mode-extras-execute
: Execute a query.
sqlite-mode-extras-add-row
: Add row to table at point.
sqlite-mode-extras-delete-row-dwim
: Similar tosqlite-mode-delete
but also enables deleting range in region.
sqlite-mode-extras-refresh
: Refreshes the buffer re-querying the database.sqlite-mode-extras-ret-dwim
: If on table, toggle expansion. If on row, edit it.sqlite-mode-extras-execute-and-display-select-query
: Executes a query and displays results.
I've been playing with the following key bindings:
(use-package sqlite-mode-extras :bind (:map sqlite-mode-map ("n" . next-line) ("p" . previous-line) ("b" . sqlite-mode-extras-backtab-dwim) ("f" . sqlite-mode-extras-tab-dwim) ("+" . sqlite-mode-extras-add-row) ("D" . sqlite-mode-extras-delete-row-dwim) ("C" . sqlite-mode-extras-compose-and-execute) ("E" . sqlite-mode-extras-execute) ("S" . sqlite-mode-extras-execute-and-display-select-query) ("DEL" . sqlite-mode-extras-delete-row-dwim) ("g" . sqlite-mode-extras-refresh) ("<backtab>" . sqlite-mode-extras-backtab-dwim) ("<tab>" . sqlite-mode-extras-tab-dwim) ("RET" . sqlite-mode-extras-ret-dwim)))
The code lives in sqlite-mode-extras.el under my Emacs config repo. Beware, it's fairly experimental and hasn't been tested thoroughly.
My custom Tesco Clubcard pkpass
My significant other and I had two plastic Tesco Clubcards. I lost mine, so I took a picture of hers. I was fairly certain a barcode photo would scan just as well at self-checkout, and it did.
This got me thinking about Apple's Wallet pkpasses. I don't really know much about them. Could I potentially create my own .pkpass
? If I could just include the same barcode as in the photo, it should do the job just fine.
Now I should mention, Tesco does have an app on the App Store. If you just want the official Wallet pass on your iPhone, use that. But I was curious about whether or not I could create my own pass.
Turns out I can. I followed Apple's building your first pass which runs you through creating Wallet identifiers/certificates, editing pass.json
, and downloading/building signpass (the utility used to sign .pass
bundles).
The signpass
utility is included in WalletCompanionFiles.zip, which comes with a handful of sample passes.
WalletCompanionFiles │ ├── SamplePasses │ │ │ ├── BoardingPass.pass │ ├── Coupon.pass │ ├── Event.pass │ ├── Event.pkpass │ ├── Generic.pass │ └── StoreCard.pass │ │ │ ├── pass.json │ └── ... └── signpass
Being a rewards card, I opted to look into StoreCard.pass
, but like all other passes, the barcode
itself is what makes each pass scannable. The barcode details are specified in the bundles's pass.json
file. I needed to figure out the relevant values describing the Tesco barcode.
"barcode": { "format": "???", "message": "???", "messageEncoding": "???" }
I had no clue what values I should use for a Tesco Clubcard. I did, however, have a photo of the barcode I needed. This is in fact what prompted looking into scanning barcodes from Emacs, which worked just great. It gave me all the crucial bits for the Clubcard.
"barcode": { "format": "PKBarcodeFormatCode128", "message": "1234567890123456", // not my actual Clubcard number of course. "messageEncoding": "iso-8859-1" }
That's all that's needed for the barcode section, the most useful part of the pass. We're not done though. We also need our registered Wallet identifiers, so the signpass
utility can sign.
"passTypeIdentifier": "my.com.identifier.passmaker", // also not my actual one. "teamIdentifier": "AAABBBCCCD", // nor this one.
We should be able to sign the pass with the following:
signpass -p StoreCard.pass
We're technically done. We now have a working card, but it looks just like the sample store card included in WalletCompanionFiles.
What's the fun in that? Now that I can make my own Clubcard, let's customize it!
For imagery, I replaced a couple of images in the .pass bundle:
StoreCard.pass │ ├── pass.json ├── icon.png ├── logo.png // replaced └── strip.png // replaced
I replaced logo.png
using a Tesco logo I found on Wikipedia. I had initially removed strip.png
, but that made the card feel a little empty. I was thinking of using a Tesco carrier bag to bulk the space up. While I didn't find a suitable bag image, I did land on "Very Little Helps, 2008". Using my limited GIMP skills, I cropped one of the images and also replaced strip.png
.
The remaining customizations took place in pass.json
and should be fairly self-explanatory. There's the text shown in all labels as well as three customizable colours (background, label, and foreground).
{ "formatVersion": 1, "passTypeIdentifier": "my.com.identifier.passmaker", // also not my actual one. "teamIdentifier": "AAABBBCCCD", // nor this one. "serialNumber": "AnySerialNumberYouWant", "barcode": { "format": "PKBarcodeFormatCode128", "message": "1234567890123456", "messageEncoding": "iso-8859-1" }, "organizationName": "Not Tesco of course", "description": "Not a Tesco reqards card", "logoText": "Clubcard", "foregroundColor": "rgb(255, 255, 255)", "labelColor": "rgb(255, 255, 255)", "backgroundColor": "rgb(2, 81, 158)", // Blue for that Tesco look "storeCard": { "auxiliaryFields": [ { "key": "membership", "label": "Member since 2023", "value": "" }, { "key": "membership2", "label": "Expires sometime", "value": "" } ] } }
…and with all that, here's what my very own custom Tesco Clubcard pkpass looks like. As you can appreciate, my image-editing skills aren't all that great, but hey this will do for now.
Update
Redditor u/stupergenius suggested using the image's original background color. Nice suggestion. Tweaked via pass.json:
"foregroundColor": "rgb(2, 81, 158)", "labelColor": "rgb(15, 58, 105)", "backgroundColor": "rgb(166, 202, 214)",
Extending sqlite-mode (cell navigation + edits)
I recently wrote about Emacs 29's new sqlite-mode, which enables you to browse sqlite databases from your beloved editor.
Out of the box, it supports the following browsing features:
sqlite-mode-list-data
: List the data from the table under point.sqlite-mode-list-column
: List the columns of the table under point.sqlite-mode-list-tables
: Re-list the tables from the currently selected database.
On the editing side of things it supports row deletion:
sqlite-mode-delete
: Delete the row under point.
While fairly spartan, it lays foundations for additional tools and features.
Two features I would like to have:
- TAB navigation across table rows and columns.
- Updating the row's field at point.
This would give me the familiar behaviour I'm used to in my org tables as well as other common spreadsheet tools.
Luckily, this is Emacs, so we can bend it our way… and I sure did!
Here's tab navigating forward:
Here's tab navigating backward:
And updating row fields:
Most of the navigation is achieved by querying the current buffer to figure out column positions. Editing was in some ways easier, as I looked at sqlite-mode-delete
to figure out how it handled the query.
To get the more familiar navigation behaviour, I've adjusted my key bindings as follows:
(use-package sqlite-mode-extras :bind (:map sqlite-mode-map ("n" . next-line) ("p" . previous-line) ("<backtab>" . sqlite-mode-extras-backtab-dwim) ("<tab>" . sqlite-mode-extras-tab-dwim) ("RET" . sqlite-mode-extras-ret-dwim)))
The code for sqlite-mode-extras-tab-dwim
, sqlite-mode-extras-backtab-dwim
, and sqlite-mode-extras-ret-dwim
is little rough still (hacky even), but hey still fun.
For now, the code lives in sqlite-mode-extras.el under my Emacs config repo. Improvements/fixes totally welcome!
Emacs 29's sqlite-mode
I've jumped on the Emacs 29 bandwagon! Mickey Petersen has a great rundown of What's New in Emacs 29.1.
Now every so often, I need to take a quick peek at an sqlite3 table. Emacs 29.1 ships sqlite-mode, which can help with that. Use sqlite-mode-open-file
to open a database.
Pressing RET
on a table shows its content via sqlite-mode-list-data
. DEL
does as you'd expect and delete a row via sqlite-mode-delete
.
Emacs: scan this QR/bar code
Another day, another tool brought to my Emacs fingertips. A while ago, I wrote about easily copying text from desktop to mobile via QR codes. Later on, I brought it under dwim-shell-command as dwim-shell-commands-clipboard-to-qr.
This time around, I needed the opposite: to scan a code from an image file. This is where zbar's zbarimg
comes in. These days, I'm mostly on macOS, so I installed via Homebrew:
$ brew install zbar
There's really nothing to the command. You feed it an image, and it outputs the scanned details. Perfect.
$ zbarimg path/to/code-128.png
CODE-128:hello world
scanned 1 barcode symbols from 1 images in 0.02 seconds
The only challenge is my brain. I probably won't remember the name of this wonderful tool next time I need it, so I'll just add it to my dwim-shell-commands.el arsenal with a memorable name:
(defun dwim-shell-commands-image-scan-code () "Scan any code from image(s)." (interactive) (dwim-shell-command-on-marked-files "Scan code" "zbarimg '<<f>>'" :utils "zbarimg"))
In the future, rather than reaching out to zbarimg
directly, I'll use my trusty fuzzy search and… voilà!
Because dwim-shell-command
operates on either dired
files or current file, we can also apply our new function when viewing the QR code itself.
dwim-shell-commands-image-scan-code
is now pushed to dwim-shell-commands.el, the optional package in dwim-shell-command.
A cure for JavaScript fatigue?
It's been roughly a decade since I wrote any significant amount of JavaScript. Back then, I primarily relied on the Google Closure Compiler, now maybe an archaeological artefact? These days, it's hard not to bump into any JavaScript project that doesn't rely on npm, along with many other tools like the Typescript compiler, ESLint, Prettier… There are a ton of available frameworks too. I was somewhat put off (or maybe just lazy?) by the initial ramp-up to reenter the JavaScript world. I guess that's what some refer to as Javascript Fatigue.
I'm giving JavaScript another try, but this time with an Emacs chatgpt-shell standing by. Reentering the JavaScript world as a noob, I often know what I want to enable, but I'm unfamiliar with which project knobs to turn to set things up.
While I may want to dig deeper into things in the future, at present I just want to dabble with JavaScript. I want a local project set up as quickly as possible. ChatGPT has been pretty handy at that. The Emacs ChatGPT shell and its minibuffer prompts work fairly well for my needs, yet I often found myself wishing it could behave more like a magit commit buffer. That is, launch a dedicated buffer (not the shell itself), ask the question, maybe paste some snippets, and send it on its way with that oh so familiar and satisfying C-c C-c
binding (sending mail also says hello).
This is where M-x chatgpt-shell-prompt-compose
comes in. It's a mash between the ChatGPT shell and a magit commit buffer:
In the background, the buffer is still powered by the shell itself, so you can reuse it to ask clarifying questions.
A couple of additional features worth mentioning… Invoking chatgpt-shell-prompt-compose
with an active region automatically copies the region content over to the compose buffer. This is handy if you'd like to create more elaborate prompts with further editing. So far, this feels more natural than editing text from the shell or the minibuffer, where RET
doesn't insert new lines.
The compose buffer is powered by a background shell (storing history for us). Typing clear
followed by C-c C-c
clears the background shell history.
chatgpt-shell-prompt-compose
is available in chatgpt-shell v0.72.1. I've so far bound it to C-c C-e
, though I've already found some unfortunate clashes.
ChatGPT visits the Emacs doctor
Emacs is a part-time job. A multi-language development environment. A lisp machine. An email client. A web browser. A zettelkasten. A spreadsheet. A mastodon client. A shell. A ledger. A super agenda. An operating system. Some say it sends ripples into the atmosphere or plays tetris for you. It may even warm your place up during the winter. Can meme with you. It's an ultra-malleable editor with endless possibilities, powered by your life-long customizations. Oh man, no wonder we need to chat to someone from time to time. You know what I mean? "Sir, this is a Wendy's".
Luckily, we also have the built-in Emacs psychotherapist we can chat to, courtesy of M-x doctor. It's powered by elisp, and like all Emacs things, it's basically up for grabs. What I mean is, elisp implements many of these features, but also glues the lot for you. Once you learn a little elisp, you can build new Emacs features but also glue others for that magical compound effect.
Figure 2: The Emacs doctor
A little while ago, I wanted to give ChatGPT a try, preferably from Emacs (of course). I figured a shell interface would be a great fit for the interaction. Emacs already shipped with a general command interpreter (comint), so I cobbled together a ChatGPT Emacs shell.
Figure 3: chatgpt-shell
So where am I going with all this? The fine netizens r/emaphis and salgernon both planted a great seed:
- "Now for extra-credit, add the ability for Alt-X doctor to psychoanalyze Chat-GPT".
- "So how about a quick M-x psychoanalyze-chatgpt?"
I haven't forgotten about you. Let's take chatgpt-shell, M-x doctor, our versatile elisp glue, and let's make them talk:
There isn't too much to the code, but beware:
- If you want to run it, you'll need chatgpt-shell installed and set up.
- This was a quick fun hack. No code judging ;)
The snippet is further down… Start with chatgpt-shell-visit-doctor
as the entry point, setting things up for us. It creates both the *chatgpt*
and *doctor*
buffers and arranges the windows next to each other.
We also set a ChatGPT system prompt to guide things a little:
"Pretend to be an overwhelmed Emacs user who is obsessed with configuring their init.el file. You are in a session talking to a psychotherapist. Limit your output to no more than 20 words. In the course of 5 exchanges between you and the therapist, show improvements. On the 8th exchange after therapist speaks, declare you are cured and only output 'Thank you doc, I think I'm cured!'"
ChatGPT and Emacs doctor can go on and on, so we limit ChatGPT responses to 20 words per response and 8 exchanges. We don't want the session to abruptly end without a resolution, so we'll use Thank you doc, I think I'm cured! as our key phrase to end the session.
We register chatgpt-shell--on-chatgpt-patient-response
as a hook to receive ChatGPT output, which we feed to the *doctor*
buffer. We subsequently get a doctor response that's fed back to ChatGPT via chatgpt-shell--insert-doc-response
.
We add some additional freebies like binding Ctrl-c Ctrl-c
to chatgpt-shell-leave-doctor
, so we can bail out of the exchange from the *chatgpt*
buffer.
We also introduced chatgpt-shell--insert-delayed-text
as a replacement for insert to slow things down a little. For visual effects, really.
(require 'chatgpt-shell) (defun chatgpt-shell-visit-doctor () (interactive) (setq chatgpt-shell--doctor-in-session t) (when (get-buffer "*doctor*") (kill-buffer "*doctor*")) (delete-other-windows) (split-window-horizontally) (other-window 1) (doctor) (visual-line-mode 1) (when (fboundp 'accent-menu-mode) (accent-menu-mode -1)) (mapc (lambda (shell-buffer) (kill-buffer shell-buffer)) (chatgpt-shell--shell-buffers)) (other-window 1) (setq chatgpt-shell-system-prompts '(("Doc" .

Ok, enough already. Let's see it in action.
If you'd like to take a closer look for analysis, here's the official transcript of this fruitful session:
I am the psychotherapist. Please, describe your problems. Each time you are finished talking, type RET twice.
I spend hours tweaking my Emacs config, but it's never perfect. I'm overwhelmed and obsessed with customization.
Is it because it's not ever perfect you are overwhelmed and obsessed with customization that you came to me?
Yes, I can't stop myself from constantly trying to tweak and improve my Emacs configuration. It's consuming me.
Emacs? Hah! I would appreciate it if you would continue.
Sorry about that. Yes, I came to you because I'm overwhelmed by my obsession with customizing my Emacs configuration.
Does it bother you that you are overwhelmed by your obsession with customizing your emacs configuration?
Absolutely! I feel trapped in an endless cycle of tweaking and configuring, unable to achieve satisfaction.
Why do you say that?
I constantly seek perfection in my Emacs config, but it's an unattainable goal that leaves me exhausted and frustrated.
When did you first know that it's an unattainable goal that leaves you exhausted and frustrated?
I've realized it recently after spending countless hours trying to perfect my Emacs configuration without any lasting satisfaction.
Are you sure?
Thanks you doc, I think I'm cured.
While we can work exclusively with the *doctor*
buffer making requests directly to the ChatGPT API, where's the fun in that? Getting the buffers to talk to each other enables us to marvel at both the beauty and absurdity of being able to glue anything together in our lovely Emacs world.
Happy Emacsing!
chatgpt-shell v0.60.1 updates
Back in April, I shared chatgpt-shell updates, showcasing chatgpt-shell features. It's been a little while, so here's an update with the latest additions.
Like this project? Consider ✨sponsoring✨.
Multi-session support
You can run multiple shell instances independently configured to use different versions or system prompts.
This was biggest recent change. Please report issues.
Display system prompt and version
The current shell's version and system prompt are now displayed more prominently in both the shell prompt and buffer name.
With multi-session support, displaying shell details in the buffer name becomes more important as it makes it easier to find shells across your buffer list.
Rename shell buffers
While buffer names are now automatically derived, one can also use chatgpt-shell-rename-buffer
to use custom buffer names.
ob-chatgpt-shell improvements
Use :temperature
to specify the temperature.
Use :context CONTEXT-NAME
to pick and choose which source blocks to aggregate as context. Thank you Thomas Moulia.
Use :preflight t
to debug ob-chatgpt-shell
execution.
chatgpt-shell-write-git-commit
Adds chatgpt-shell-write-git-commit
, so you can generate commit messages using the current region. Thank you Simon Judd.
Approximate context length
chatgpt-shell
now uses chatgpt-shell--approximate-context-length
to approximate the context size and discard history if necessary. This is pretty experimental but seems to work well enough. It's enabled by default to get some feedback. Please file bugs if needed or send PRs to improve.
S-<return>
for multiline input
In addition to C-J
to insert multi-line input, S-<return>
is also supported. Thank you shouya for the submission.
Welcome message
A welcome message now makes the help much more discoverable for new or sporadic users. Thank you shouya for the suggestion.
Help me
While the README documents the shells and Emacs is self-documenting, we now have a help
command to make things a little more discoverable.
Hello chatgpt-shell-mode and dall-e-shell-mode
Both chatgpt-shell
and dall-e-shell
are both based on shell-maker
and until recently both shared shell-maker-mode
as their major mode. This didn't play well with yasnippet. Both shells now enable independent major modes: chatgpt-shell-mode
and dall-e-shell-mode
. Thank you Daniel Liden for the proposal.
Saving transcript customizations
Make transcript saving more customizable via shell-maker-transcript-default-path
and shell-maker-transcript-default-filename
. Thank you gnusupport.
New ChatGPT model versions
New OpenAI model versions were recently released and added to chatgpt-shell: gpt-3.5-turbo-0613
and gpt-4-0613
. Thanks you Norio Suzuki.
Load awesome prompts
M-x chatgpt-shell-load-awesome-prompts
to download and import curated prompts from awesome-chatgpt-prompts. Thank you Daniel Gomez.
ob-async
We had reports that ob-chatgpt-shell didn't play nice with ob-async. Thank you William Medrano for the solution.
Configurable prompts
Functions like chatgpt-shell-describe-code
ask ChatGPT to describe the code in region. These functions used hardcoded English prompts. These are now configurable, so users can tweak or translate if preferred. Thank you Norio Suzuki.
chatgpt-shell-prompt-header-describe-code
chatgpt-shell-prompt-header-refactor-code
chatgpt-shell-prompt-header-generate-unit-test
chatgpt-shell-prompt-header-proofread-region
chatgpt-shell-prompt-header-whats-wrong-with-last-command
chatgpt-shell-prompt-header-eshell-summarize-last-command-output
Duplicate this!
James Dyer has a nice post sharing his frequent dired need to duplicate files. He offers a solution using a custom interactive command. His use-case resonated with me.
Similarly, James' recommendation to bind his file-duplicating command to C-c d
[1] sent a signal to my brain triggering Bozhidar Batsov's crux-duplicate-current-line-or-region
.
crux-duplicate-current-line-or-region
is part of a "collection of Ridiculously useful extensions for Emacs" (yeah that's crux). The command itself does what it says on the tin.
Let's duplicate the current line.
Now let's duplicate the current region.
Since I already have a well-internalized key-binding duplicating lines/regions in text buffers, I could extend a similar behaviour to dired files with almost zero adoption effort.
In case you haven't noticed, I've made it a part-time job to make command line utilities easily accessible from Emacs (1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21) via dwim-shell-command. Partly because it's fairly quick and partly 'cause it's fun.
Jame's post gave me yet another opportunity to exercise my errrm part-time job. This time, duplicating files. All I need is the cp utility and a template:
cp -R '<<f>>' '<<f(u)>>'
I seldom type these template's myself when I want to execute a command (via M-x dwim-shell-command
). I typically wrap these templates in interactive commands, making them easily accessible via M-x
and your favorite completion framework. I happen to use ivy.
(require 'dwim-shell-command) (defun dwim-shell-commands-duplicate () "Duplicate file(s)." (interactive) (dwim-shell-command-on-marked-files "Duplicate file(s)." "cp -R '<<f>>' '<<f(u)>>'" :utils "cp"))
There's nothing much to the command. Most logic is handled by the template, replacing <<f>>
with the current file and <<f(u)>>
with a uniquified version of it. Having said this, there's a bunch of free DWIM love that kicks in, courtesy of the dwim-shell-command
package by yours truly. Let's give our new dwim-shell-commands-duplicate
command a spin.
Like crux-duplicate-current-line-or-region
duplicates the current line, our new command duplicates the current dired file.
Got multiple files to duplicate? Like crux-duplicate-current-line-or-region
, we can use the region for a similar purpose.
While we have been using the region to duplicate adjacent files, we can also mark specific files.
Our cp -R '<<f>>' '<<f(u)>>'
template uses the -R
(recursive) flag, so we get another freebie. In addition to files, we can also duplicate directories.
Lastly, because we're on a DWIM train, if your current buffer happens to be visiting a file, you can M-x dwim-shell-commands-duplicate
the current file to duplicate it. You're automatically dropped to a dired buffer, with point on the new file (à la dired-jump).
While duplicating files using a template was a mere cp -R '<<f>>' '<<f(u)>>'
away, we get a bunch of free DWIM magic applied to a handful of use-cases and contexts. What made the file-duplicating use-case extra special is that it maps almost exactly to an equivalent text command. Keep the same key bindings and we almost get a "free feature".
(use-package crux :ensure t :commands crux-open-with :bind (("C-c d" . crux-duplicate-current-line-or-region))) (use-package dwim-shell-command :ensure t :bind (:map dired-mode-map ("C-c d" . dwim-shell-commands-duplicate)) :config ;; Loads all my own dwim shell commands ;; (including `dwim-shell-commands-duplicate') (require 'dwim-shell-commands))
You can find my ever-growing list of similar commands over at dwim-shell-commands.el (the optional part of the package). Got some nifty usages? Would love to check 'em out. Get in touch.

Update
If you're keen on a regex-based approach, u/arthurno1 offers a great built-in alternative: dired-do-copy-regexp (bound to % C
).
Stitching images from the comfort of dired
I recently wanted a few images stitched together. A perfect job for ImageMagick. A quick search yielded the magical incantation:
convert image1.jpg image2.jpg image3.jpg +append joined.jpg
Great, now I know, but I'll rarely use it and will soon forget it. I may as well add it to my repository of DWIM command line utilities, wrapped in a convenient Emacs function, applicable from different contexts… know what I mean? 🙃
I built dwim-shell-command for this purpose. You can take the above command and easily turn it into an interactive Emacs command with something like the following:
(require 'dwim-shell-command) (defun dwim-shell-commands-join-images-horizontally () "Join all marked images horizontally as a single image." (interactive) (dwim-shell-command-on-marked-files "Join images horizontally" "convert -verbose '<<*>>' +append 'joined.jpg'" :utils "convert"))
You can select as many images as you'd like from the comfort of your dired and make the ImageMagick happen.
The snippet does the job just fine, but we can make it smarter. For starters, let's not hardcode the output filename. We'll ask the user instead. While we're asking, let's offer a default filename, but let's not assume the output extension is .jpg
. Let's guess based on the image selection. While we're at it, let's not override the output file if already exists. Uniquify it.
Most of the above can be achieved by either using dwim-shell-command helpers or its templating language. For example, <<joined.png(u)>>
ensures that if joined.png
already exists, it automatically generates joined(1).png
instead.
(require 'dwim-shell-command) (defun dwim-shell-commands-join-images-horizontally () "Join all marked images horizontally as a single image." (interactive) (let ((filename (format "joined.%s" (or (seq-first (dwim-shell-command--file-extensions)) "png")))) (dwim-shell-command-on-marked-files "Join images horizontally" (format "convert -verbose '<<*>>' +append '<<%s(u)>>'" (dwim-shell-command-read-file-name (format "Join as image named (default \"%s\"): " filename) :default filename)) :utils "convert")))
Here's the new horizontal command in action…
Notice how this time we didn't mark the images using dired-mark
, typically bound to m
. Instead, we made our selection using the region. Also, if you haven't gotten your junk food fix yet, here's the fries equivalent ;)
We'll rinse all and repeat to get the vertical command equivalent. I know, I know, there's fair amount of duplication but c'est la vie.
(require 'dwim-shell-command) (defun dwim-shell-commands-join-images-vertically () "Join all marked images vertically as a single image." (interactive) (let ((filename (format "joined.%s" (or (seq-first (dwim-shell-command--file-extensions)) "png")))) (dwim-shell-command-on-marked-files "Join images vertically" (format "convert -verbose '<<*>>' -append '<<%s(u)>>'" (dwim-shell-command-read-file-name (format "Join as image named (default \"%s\"): " filename) :default filename)) :utils "convert")))
…and for our grand finale, we'll vertically join our burgers and fries. Behold!
These commands are now part of dwim-shell-command. To get them, load the optional commands via (require 'dwim-shell-commands)
.
noweb: the lesser known org babel glue
While Org babel's noweb isn't something I've frequently used for literate programming, its simplicity makes it rather versatile to glue all sorts of babel things I hadn't previously considered.
The idea is simple. Add a placeholder like <<other-block>>
to an org babel source block, and it will be automatically replaced (verbatim) with the content (or result) of referred block before execution. You'll also need the :noweb yes
header argument.
#+NAME: other-block #+begin_src swift print("Hello 0") #+end_src #+RESULTS: other-block : Hello 0 #+BEGIN_SRC swift :noweb yes <<other-block>> print("Hello 1") #+END_SRC #+RESULTS: : Hello 0 : Hello 1
Since <<other-block>>
is replaced with the content of said block, at execution time, the block is effectively equivalent to executing:
print("Hello 0") print("Hello 1")
Hello 0 Hello 1
Why is this so versatile? Org babel can include/execute all sorts of languages, so you can mix and match the result from one language and massage it to appear as the body of another block using the same (or different) language.
I was recently asked how to include the result from one babel block in another using ob-chatgpt-shell. While the initial question was looking for a solution involving variables, we can use noweb to achieve a similar goal.
Note that in this case, I'll be using <<hello()>>
, with ()
, to refer to #+RESULTS:
rather than the source block itself.
#+NAME: hello #+BEGIN_SRC chatgpt-shell Say hello in spanish #+END_SRC #+RESULTS: hello Hola #+BEGIN_SRC chatgpt-shell :noweb yes <<hello()>> What does the previous line say verbatim? #+END_SRC
Executing the block
<<hello()>> What does the previous line say verbatim?
Gives us
The previous line says "Hola".
On a similar note, I was asked if the results from a previous source block could be fed to a Swift Chart block using ob-swiftui.
While I'm new to Swift Charts, I do love glueing things via Emacs lisp. I figured I could write a little elisp to generate random data and feed it to a SwiftUI block via <<data()>>
. The result is pretty neat, based on Apple's LineMark example.
#+NAME: data #+begin_src emacs-lisp :lexical no (concat (mapconcat (lambda (n) (format "MonthlyHoursOfSunshine(city: \"Seattle\", month: %d, hoursOfSunshine: %d)," n (random 100))) (number-sequence 1 20) "\n") "\n" (mapconcat (lambda (n) (format "MonthlyHoursOfSunshine(city: \"Cupertino\", month: %d, hoursOfSunshine: %d)," n (random 100))) (number-sequence 1 20) "\n")) #+end_src #+begin_src swiftui :results file :noweb yes import Charts struct MonthlyHoursOfSunshine: Identifiable { var city: String var date: Date var hoursOfSunshine: Double var id = UUID() init(city: String, month: Int, hoursOfSunshine: Double) { let calendar = Calendar.autoupdatingCurrent self.city = city self.date = calendar.date(from: DateComponents(year: 2020, month: month))! self.hoursOfSunshine = hoursOfSunshine } } struct ContentView: View { var data: [MonthlyHoursOfSunshine] = [ <<data()>> ] var body: some View { Chart(data) { LineMark( x: .value("Month", $0.date), y: .value("Hours of Sunshine", $0.hoursOfSunshine) ) .foregroundStyle(by: .value("City", $0.city)) } .frame(minWidth: 800, minHeight: 300) .padding() .colorScheme(.dark) } } #+end_src
While I've shown fairly basic usages of noweb, we can accomplish some nifty integrations. Check out the noweb reference syntax for more examples and additional header arguments like tangle
, strip-tangle
, and others.
Deleting from Emacs sequence vars
Adding hooks and setting variables is core to customizing Emacs. Take a major mode like
emacs-lisp-mode
as an example. To customize its behaviour, one may add a hook function to emacs-lisp-mode-hook
, or if you're a little lazy while experimenting, you may even use a lambda.
(add-hook 'emacs-lisp-mode-hook #'my/emacs-lisp-mode-config) (add-hook 'emacs-lisp-mode-hook (lambda () (message "I woz ere")))
emacs-lisp-mode-hook
's content would subsequently look as follows:
'(my/emacs-lisp-mode-config (lambda nil (message "I woz ere")) ert--activate-font-lock-keywords easy-escape-minor-mode lisp-extra-font-lock-global-mode)
Maybe my/emacs-lisp-mode-config
didn't work out for us and we'd like to remove it. We can use remove-hook
for that and evaluate something like:
(remove-hook 'emacs-lisp-mode-hook #'my/emacs-lisp-mode-config)
The lambda can be removed too, but you ought to be careful in using the same lambda body.
(remove-hook 'emacs-lisp-mode-hook (lambda () (message "I woz tere")))
There are other ways to remove the lambdas, but we're digressing here… We typically have to write these throwaway snippets to undo our experiments. What if we just had a handy helper always available to remove items from sequences (edit: we do, remove-hook
is already interactive, see Update 2 below)? After all, hooks are just lists (sequences).
While the interactive command can likely be simplified further, I tried to optimize for ergonomic usage. For example, completing-read
gives us a way narrow down whichever variable we'd like to modify as well as the item we'd like to remove. seqp
is also handy, as we filter out noise by automatically removing any variable that's not a sequence.
(defun ar/remove-from-list-variable () (interactive) (let* ((var (intern (completing-read "From variable: " (let (symbols) (mapatoms (lambda (sym) (when (and (boundp sym) (seqp (symbol-value sym))) (push sym symbols)))) symbols) nil t))) (values (mapcar (lambda (item) (setq item (prin1-to-string item)) (concat (truncate-string-to-width (nth 0 (split-string item "\n")) (window-body-width)) (propertize item 'invisible t))) (symbol-value var))) (index (progn (when (seq-empty-p values) (error "Already empty")) (seq-position values (completing-read "Delete: " values nil t))))) (unless index (error "Eeek. Something's up.")) (set var (append (seq-take (symbol-value var) index) (seq-drop (symbol-value var) (1+ index)))) (message "Deleted: %s" (truncate-string-to-width (seq-elt values index) (- (window-body-width) 9)))))
Hooks are just an example of lists we can delete from. I recently used the same command on display-buffer-alist
.
While this has been a fun exercise, I can't help but think that I'm likely re-inventing the wheel here. Is there something already built-in that I'm missing?
Update 1
alphapapa suggested some generalizations that would provide an editing buffer of sorts. This is a neat idea, using familiar key bindigs C-c C-c
to save and C-c C-k
to bail.
Beware, I haven't tested the code with a diverse set of list items, so there's a chance of corrupting the variable content. Improvements to the code are totally welcome.
;;; -*- lexical-binding: t; -*- (defun ar/edit-list-variable () (interactive) (let* ((var (intern (completing-read "From variable: " (let (symbols) (mapatoms (lambda (sym) (when (and (boundp sym) (seqp (symbol-value sym))) (push sym symbols)))) symbols) nil t))) (values (string-join (mapcar #'prin1-to-string (symbol-value var)) "\n"))) (with-current-buffer (get-buffer-create "*eval elisp*") (emacs-lisp-mode) (local-set-key (kbd "C-c C-c") (lambda () (interactive) (eval-buffer) (kill-this-buffer) (message "Saved: %s" var))) (local-set-key (kbd "C-c C-k") 'kill-this-buffer) (erase-buffer) (insert (format "(setq %s\n `(%s))" var values)) (mark-whole-buffer) (indent-region (point-min) (point-max)) (deactivate-mark) (switch-to-buffer (current-buffer)))))
Update 2
So hunch was right…
"While this has been a fun exercise, I can't help but think that I'm likely re-inventing the wheel here. Is there something already built-in that I'm missing?"
juicecelery's Reddit commit confirmed it. Thank you! remove-hook is already interactive 🤦♂️. TIL 😁
juicecelery was kind enough to point out an improvement in the custom function:
"but I see your improvements, for instance that non list items are removed from the selection."
Sprinkle me logs
At times, basic prints/logs are just about the right debugging strategy. Sure, we have debuggers and REPLs which are super useful, but sometimes you just know that sprinkling your code with a handful of temporary prints/logs will get you enough info to fix an issue.
I must confess, my temporary print statements are fairly uninspiring. Sometimes I log the name of the method/function, but I also resort to less creative options like print("Yay")
or print("Got here")
.
My laziness and lack of creativity knows no boundaries, so if I need multiple unique entries, I often copy, paste, and append numbers to my entries: print("Yay 2")
, print("Yay 3")
, print("Yay 4")
… I know, are you judging yet?
So rather than develop the creative muscle, I've decided to lean on laziness and old habits, so let's make old habit more efficient :) I no longer want to copy, paste, and increment my uncreative log statements. Instead, I'll let Emacs do it for me!
There isn't a whole lot to the implementation. It searches the current buffer for other instances of the same logging string and captures the largest counter found. It subsequently prints the same string with the counter incremented. This can be done in a few lines of elisp, but I figure I wanted some additional features like auto indenting and changing the logging string when using a prefix.
(defvar ar/unique-log-word "Yay") (defun ar/insert-unique-log-word (prefix) "Inserts `ar/unique-log-word' incrementing counter. With PREFIX, change `ar/unique-log-word'." (interactive "P") (let* ((word (cond (prefix (setq ar/unique-log-word (read-string "Log word: "))) ((region-active-p) (setq ar/unique-log-word (buffer-substring (region-beginning) (region-end)))) (ar/unique-log-word ar/unique-log-word) (t "Reached"))) (config (cond ((equal major-mode 'emacs-lisp-mode) (cons (format "(message \"%s: \\([0-9]+\\)\")" word) (format "(message \"%s: %%s\")" word))) ((equal major-mode 'swift-mode) (cons (format "print(\"%s: \\([0-9]+\\)\")" word) (format "print(\"%s: %%s\")" word))) ((equal major-mode 'ada-mode) (cons (format "Ada.Text_Io.Put_Line (\"%s: \\([0-9]+\\)\");" word) (format "Ada.Text_Io.Put_Line (\"%s: %%s\");" word))) ((equal major-mode 'c++-mode) (cons (format "std::cout << \"%s: \\([0-9]+\\)\" << std::endl;" word) (format "std::cout << \"%s: %%s\" << std::endl;" word))) (t (error "%s not supported" major-mode)))) (match-regexp (car config)) (format-string (cdr config)) (max-num 0) (case-fold-search nil)) (when ar/unique-log-word (save-excursion (goto-char (point-min)) (while (re-search-forward match-regexp nil t) (when (> (string-to-number (match-string 1)) max-num) (setq max-num (string-to-number (match-string 1)))))) (setq max-num (1+ max-num))) (unless (looking-at-p "^ *$") (end-of-line)) (insert (concat (if (looking-at-p "^ *$") "" "\n") (format format-string (if ar/unique-log-word (number-to-string (1+ max-num)) (string-trim (shell-command-to-string "grep -E '^[a-z]{6}$' /usr/share/dict/words | shuf -n 1")))))) (call-interactively 'indent-for-tab-command)))
Note: This snippet may evolve independently of this post. For the latest, chech my Emacs config's fe-prog.el.
I want to be lazy in other languages, so the function can now be extended to support other languages. Here's the Swift counterpart.
Since I sometimes log function names, I figured making it region-aware would help with that.
I'm sure there's a package out there that does something similar, but I figure this would be a fun little elisp hack.
Happy logging!
Update 1
Set ar/unique-log-word
to nil and let it generate a random word. Maybe I get to learn new words as I debug ;)
Update 2
Added Ada and C++ support, thanks to James Dyer's post.
dwim-shell-command on Windows + upload to 0x0.st
You can now use dwim-shell-command on Windows. Shoutout to Kartik Saranathan, who sent a pull request to get rid of ls
usage.
Also thanks to Bram for sharing his upload to 0x0.st implementation. I'd been wanting to do something similar for imgur, but 0x0.st is a much better alternative!
dwim-shell-commands-upload-to-0x0
is now part of dwim-shell-commands.el (the optional part of the package). It has a couple of additional touches:
- Open the uploaded image in eww browser.
- Automatically copy the upload URL to kill-ring. You're likely gonna share this link, right?
If you're unfamiliar with dwim-shell-command
, it enables Emacs shell commands with DWIM behaviour:
- Asynchronously.
- Using noweb templates.
- Automatically injecting files (from dired or other buffers) or kill ring.
- Managing buffer focus with heuristics.
- Showing progress bar.
- Quick buffer exit.
- More reusable history.
In addition to replacing shell-command
with dwim-shell-command
, I also use it to bring all sorts of command line utilities to familiar Emacs workflows (in dired or current buffers), without having to remember complex command invocations.
I've covered many of the use-cases before:
- Emacs DWIM shell-command
- Emacs: Password-protect current pdf (revisited)
- png to icns (Emacs DWIM style)
- Emacs: DWIM shell command (multi-language)
- dwim-shell-command on Melpa
- dwim-shell-command improvements
- dwim-shell-command video streams
- dwim-shell-command with template prompts
- dwim-shell-command usages: pdftotext and scp
- Emacs: Reveal in macOS Finder (DWIM style)
- Emacs: macOS sharing (DWIM style)
chatgpt-shell siblings now on MELPA also
In chatgpt-shell updates, I highlighted dall-e-shell
(a DALL-E Emacs shell), ob-chatgpt-shell
(ChatGPT org babel support), and ob-dall-e-shell
(DALL-E org babel support) were initially excluded from the chatgpt-shell MELPA submission while I worked out their split.
That's now sorted and the packages are available on MELPA.
Here's ob-chatgpt-shell
and ob-dall-e-shell
in action.
Here's dall-e-shell
.
Generating elisp org docs
chatgpt-shell's README includes few org tables documenting the package's customizable variables as well as available commands. Don't worry, this isn't really another ChatGPT post.
Here's an extract of the docs table:
| Custom variable | Description | |---------------------------------------+-------------------------------------------------------------| | chatgpt-shell-display-function | Function to display the shell. | | chatgpt-shell-curl-additional-options | Additional options for `curl' command. | | chatgpt-shell-system-prompt | The system message helps set the behavior of the assistant. |
While the table docs didn't take long to build manually, they quickly became out of sync with their elisp counterparts. Not ideal, as it'll require a little more careful maintenance in the future.
Emacs being the self-documenting editor that it is, I figured I should be able to extract customizable variables, commands, along with their respective docs, and generate these very same org tables.
I had no idea how to go about this, but apropos-variable and apropos-command surely knew where to fetch the details from. A peak into apropos.el
quickly got me on my way. Turns out mapatoms is just what I needed. It iterates over obarray, Emacs's symbol table. We can use it to extract the symbols we're after.
Since we're filtering symbols from chatgpt-shell
, we can start by including only those whose symbol-name
match "^chatgpt-shell". Out of all matching, we should only keep custom variables. We can use custom-variable-p
to check for that. This gives us all relevant variables. We can subsequently get each variable's corresponding docs using (get symbol 'variable-documentation)
and put it into a list.
Now, if we pull our org babel rabbit out of our Emacs magic hat, we can use :results table
to print the list as an org table. The source block powering this magic trick looks as follows:
#+begin_src emacs-lisp :results table :colnames '("Custom variable" "Description") (let ((rows)) (mapatoms (lambda (symbol) (when (and (string-match "^chatgpt-shell" (symbol-name symbol)) (custom-variable-p symbol)) (push `(,symbol ,(car (split-string (or (get (indirect-variable symbol) 'variable-documentation) (get symbol 'variable-documentation) "") "\n"))) rows)))) rows) #+end_src
And just like that… we effortlessly get our elisp docs in an org table, straight from Emacs's symbol table.
It's worth noting that our snippet used indirect-variable
to resolve aliases but also limited descriptions to the first line in each docstring.
To build a similar table for interactive commands, we can use the following block (also including bindings).
#+BEGIN_SRC emacs-lisp :results table :colnames '("Binding" "Command" "Description") (let ((rows)) (mapatoms (lambda (symbol) (when (and (string-match "^chatgpt-shell" (symbol-name symbol)) (commandp symbol)) (push `(,(mapconcat #'help--key-description-fontified (where-is-internal symbol shell-maker-mode-map nil nil (command-remapping symbol)) ", ") ,symbol ,(car (split-string (or (documentation symbol t) "") "\n"))) rows)))) rows) #+END_SRC
You see? This post wasn't really about ChatGPT. Aren't you glad you stuck around? 😀

chatgpt-shell updates
About a month ago, I posted about an experiment to build a ChatGPT Emacs shell using comint mode. Since then, it's turned into a package of sorts, evolving with user feedback and pull requests.
Now on MELPA
While chatgpt-shell is a young package still, it seems useful enough to share more widely. As of today, chatgpt-shell
is available on MELPA. Many thanks to Chris Rayner for his MELPA guidance to get the package added.
I'll cover some of the goodies included in the latest chatgpt-shell
.
Delegating to Org Babel
chatgpt-shell
now evaluates Markdown source blocks by delegating to org babel. I've had success with a handful of languages. In some instances, some babel headers may need overriding in chatgpt-shell-babel-headers
.
Here's a Swift execution via babel, showing standard output.
In addition to standard output, chatgpt-shell
can now render blocks generating images. Here's a rendered SwiftUI layout via ob-swiftui.
Can also do diagrams. Here's ditaa in action.
Renaming blocks
At times, ChatGPT may forget to label source blocks or maybe you just want to name it differently… You can now rename blocks at point.
Send prompt/region
There are a handful of commands to send prompts from other buffers, including the region. For example chatgpt-shell-explain-code
.
- chatgpt-shell-send-region
- chatgpt-shell-generate-unit-test
- chatgpt-shell-refactor-code
- chatgpt-shell-proofread-doc
- chatgpt-shell-eshell-summarize-last-command-output
- chatgpt-shell-eshell-whats-wrong-with-last-command
Saving/restoring transcript
You can save your current session to a transcript and restore later.
History improvements
Nicolas Martyanoff has a great post on making IELM More Comfortable. A couple of improvements that stood out for me were:
- Making the command history persistent.
- Searching history with
shell-maker-search-history
/M-r
viacompleting-read
.
shell-maker-search-history
, coupled with your completion framework of choice, can be pretty handy. I happen to use Oleh Krehel's ivy.
shell-maker (make your own AI shells)
While ChatGPT is a popular service, there are many others sprouting. Some are cloud-based, others local, proprietary, open source… In any case, it'd be great be able to hook on to them without much overhead. shell-maker should help with that. The first shell-maker
clients are chatgpt-shell
and dall-e-shell
.
While I've built dall-e-shell
, it'd be great to see what others can do with shell-maker
. If you wire it up to anything, please get in touch (Mastodon / Twitter / Reddit / Email).
dall-e-shell, ob-chatgpt-shell, and ob-dall-e-shell (on MELPA too)
UPDATE: dall-e-shell, ob-chatgpt-shell, and ob-dall-e-shell are now available on MELPA also.
You've seen dall-e-shell
in the previous section. Here's what ob-chatgpt-shell
and ob-dall-e-shell
look like in an org mode document:
How are you using chatgpt-shell
?
Whether you are an existing chatgpt-shell
user, or would like to give things a try, installing from MELPA should generally make things easier for ya. As I mentioned, chatgpt-shell
is a young package still. There are unexplored Emacs integrations out there. I'd love to hear about whatever you come up with (Mastodon / Twitter / Reddit / Email).
Recording and screenshotting windows: the lazy way
While there's no substitution for great written documentation, a quick demo can go a long way in conveying what a tool if capable of doing or what a tip/trick can achieve.
If you've read a handful of my posts, you would have come across either a screenshot or a short clip with some demo. Historically, I've used the macOS's built-in utility invoked via ⌘ + Shift + 5
. It does a fine job for screenshots. For video captures, it's got a couple of small quirks.
Record window
Unlike screenshots, macOS video capture cannot record a specific window. While you can select a region, it's easy to inadvertently include a portion of your wallpaper in the recording. Not a big deal, but I felt posted screencasts could look as clean as their screenshot counterparts if we could record the window alone.
Let's compare grabbing a region vs window alone. I know the clean look may be subjective, but see what I mean?
Figure 5: Capture region (includes wallpaper/background)
Figure 6: Capture window only (ahhh, so clean)
Cancel recording
macOS has a handy shortcut (⌘ + Ctrl + Esc
) to stop recording. If you got your demo right, you're done. If not, you have one more step remaining (right click to delete the blooper).
Also not a huge deal, but I was hoping for a single shortcut to stop recording and also automatically discard. I haven't found one, but would love to hear if otherwise.
macosrec enters the chat
I wanted more flexibility to build my own recording/screenshotting flows. A command line utility could be quite versatile at that, so I built macosrec.
macosrec
enables taking a screenshot or recording a window video entirely from the command line.
elisp glues the world
Command line utilities can be invoked in all sorts of ways, but I'm an Emacs nutter so you can see where this is going… I want Emacs key bindings to control the lot.
C-c _ | Take screenshot of a window |
C-c ( | Start recording window |
C-c ) | Stop recording window |
C-c 8 | Abort recording |
Integrating command line utilities into Emacs and making them quickly accessible seems to have become a full-time hobby of mine. I kid, but it's become a pretty painless process for me. I built dwim-shell-command for that. If you've never heard of DWIM, it stands for "Do what I mean". To give you an idea of the kinds of things I'm using DWIM commands for, check the following out:
- dwim-shell-commands-audio-to-mp3
- dwim-shell-commands-bin-plist-to-xml
- dwim-shell-commands-clipboard-to-qr
- dwim-shell-commands-drop-video-audio
- dwim-shell-commands-files-combined-size
- dwim-shell-commands-git-clone-clipboard-url
- dwim-shell-commands-git-clone-clipboard-url-to-downloads
- dwim-shell-commands-image-to-grayscale
- dwim-shell-commands-image-to-icns
- dwim-shell-commands-image-to-jpg
- dwim-shell-commands-image-to-png
- dwim-shell-commands-pdf-password-protect
- dwim-shell-commands-reorient-image
- dwim-shell-commands-resize-gif
- dwim-shell-commands-resize-image
- dwim-shell-commands-resize-video
- dwim-shell-commands-speed-up-gif
- dwim-shell-commands-speed-up-video
- dwim-shell-commands-unzip
- dwim-shell-commands-video-to-gif
- dwim-shell-commands-video-to-optimized-gif
- dwim-shell-commands-video-to-webp
If it ever took you a little while to find the right command incantation to get things right, only to forget all about it next time you need it (I'm looking at you ffmpeg), dwim-shell-command
can help you easily save things for posterity and make them easily accessible in the future.
Since we're talking ffmpeg, here's all it takes to have gif conversion handy:
(defun dwim-shell-commands-video-to-gif () "Convert all marked videos to gif(s)." (interactive) (dwim-shell-command-on-marked-files "Convert to gif" "ffmpeg -loglevel quiet -stats -y -i '<<f>>' -pix_fmt rgb24 -r 15 '<<fne>>.gif'" :utils "ffmpeg"))
There's no way I'll remember the ffmpeg command, but I can always fuzzy search my trusty commands with something like "to gif"
and apply to either the current buffer file or any selected dired files.
So where am I going with this? I wrote DWIM shell commands for the bindings I previously described:
C-c _ | dwim-shell-commands-macos-screenshot-window |
C-c ( | dwim-shell-commands-macos-start-recording-window |
C-c ) | dwim-shell-commands-macos-end-recording-window |
C-c 8 | dwim-shell-commands-macos-abort-recording-window |
Out of all of commands, dwim-shell-commands-macos-start-recording-window
is likely the most interesting one.
(defun dwim-shell-commands-macos-start-recording-window () "Select and start recording a macOS window." (interactive) (let* ((window (dwim-shell-commands--macos-select-window)) (path (dwim-shell-commands--generate-path "~/Desktop" (car window) ".mov")) (buffer-file-name path) ;; override so <<f>> picks it up (inhibit-message t)) (dwim-shell-command-on-marked-files "Start recording a macOS window." (format "# record .mov macosrec --record '%s' --mov --output '<<f>>' # speed .mov up x1.5 ffmpeg -i '<<f>>' -an -filter:v 'setpts=1.5*PTS' '<<fne>>_x1.5.<<e>>' # convert to gif x1.5 ffmpeg -loglevel quiet -stats -y -i '<<fne>>_x1.5.<<e>>' -pix_fmt rgb24 -r 15 '<<fne>>_x1.5.gif' # speed .mov up x2 ffmpeg -i '<<f>>' -an -filter:v 'setpts=2*PTS' '<<fne>>_x2.<<e>>' # convert to gif x2 ffmpeg -loglevel quiet -stats -y -i '<<fne>>_x2.<<e>>' -pix_fmt rgb24 -r 15 '<<fne>>_x2.gif'" (cdr window)) :silent-success t :monitor-directory "~/Desktop" :no-progress t :utils '("ffmpeg" "macosrec"))))
As you likely expect, this command invokes macosrec
to start recording a window. The nifty part is that when it's done recording (and saving the .mov file), it automatically creates multiple variants. For starters, it creates x1.5 and x2 .mov videos, but it also generates their .gif counterparts.
Let's recap here for a sec. You start recording a window video with C-c (
, end with C-c )
, and automagically have all these generated files waiting for you.
You can subsequently inspect any of the video candidates and pick the most appropriate variant. Discard whatever else you don't need.
The output bundle is tailored to my needs. Maybe you want to invoke gifsycle for more optimized versions? Or maybe you want automatic webp generation via ffmpeg
? DWIM does that I mean, so you likely have other plans…
dwim-shell-commands-macos-start-recording-window
and all other DWIM commands are now included in dwim-shell-commands.el, which ships optionally as part of dwim-shell-command.
macosrec is also on GitHub, but if you want to be on your way, you can install via:
brew tap xenodium/macosrec brew install macosrec
This is my way to record and screenshot windows the lazy way. How would you tweak to make it yours?
ob-swiftui updates
While experimenting with delegating Markdown blocks to Org babel in Emacs chatgpt-shell, I resurrected ob-swiftui. A package I had written to execute and render SwiftUI blocks in org babel.
ob-swiftui has two modes of rendering SwiftUI blocks: :results window
, which runs outside of Emacs in a native window and :results file
, which renders and saves to a file. The latter can be viewed directly from Emacs.
:results file
was a little clunky. That is, it hardcoded dimensions I had to manually modify if the canvas wasn't big enough. It was also a little slow.
The clunkyness really came through with my chatgpt-shell experiments, so I took a closer look and made a few changes to remove hardcoding and speeds things up.
The results ain't too shabby.
Another tiny improvement is that if you'd like to compose a more complex layout made of multiple custom views, ob-swiftui
now looks for a ContentView
as that root view by default. Specifying another root view was already possible but it had to be explicitly requested via :view
param.
You can now omit the :view
param if you name the root view ContentView
:
#+begin_src swiftui struct ContentView: View { var body: some View { TopView() BottomView() } } struct TopView: View { var body: some View { Text("Top text") } } struct BottomView: View { var body: some View { Text("Bottom text") } } #+end_src
The improvements have been pushed to ob-swiftui and will soon be picked up on melpa.
Edit: Added ContentView details.
My Emacs eye candy
I get the occasional question about my Emacs theme, font, and other eye candy. I'm always tickled and happy to share.
It's been a while since I've made visually significant changes to my Emacs config. May as well briefly document for posterity…
Nyan Mode
First things first. The adorable and colorful little fella in my mode line is a Nyan Cat (if you dare, check the meme video). Yes, I know it's sooo 2011, but it's 2023 and I still love the little guy hanging out in my Emacs mode line. I still get asked about it.
This fabulous feature comes to us via the great Nyan Mode package. If looks haven't convinced you, Nyan also packs scrolling functionality. Click anywhere in it.
Oh, and if you can't get enough of Nyan, there's also zone-nyan for Emacs.
Emacs Plus (macOS)
I should mention I'm running Emacs 28 on macOS via the excellent Emacs Plus homebrew recipe. These are all the options I enable.
brew install emacs-plus@28 --with-imagemagick --with-no-frame-refocus --with-native-comp --with-savchenkovaleriy-big-sur-icon
Icon
Since we're talking eye candy, let's chat about --with-savchenkovaleriy-big-sur-icon
. This Emacs Plus option enables Valeriy Savchenko's wonderful icon.
Titlebar
I've enabled both transparent title bar as well as dark appearance, giving a minimal window decoration.
(add-to-list 'default-frame-alist '(ns-transparent-titlebar . t)) (add-to-list 'default-frame-alist '(ns-appearance . dark))
Note: both of these variables are prefixed ns-
(macOS-only settings).
Font (JetBrains Mono)
I've been on JetBrains Mono font for quite some time now. In the past, I've also been a fan of Mononoki and Menlo (on macOS) or Meslo (similar elsewhere).
Theme (Material)
I'm using the great Material Theme for Emacs, with a bunch of tweaks of my own.
Modeline tabs/ribbons (Moody)
The moody package adds a nice touch displaying mode line elements as tabs and ribbons.
Modeline menus (Minions)
The minions package removes lots of minor mode clutter from the mode line and stashes it away in menus.
Hiding modeline (hide mode line mode)
Hiding the mode line isn't something I use in most major modes. However, I found it complements my shell (eshell) quite well. While I was sceptical at first, once I hid the mode line in my shell I never looked back. I just didn't miss it. I also love the uncluttered clean vibe. hide-mode-line-mode can help with that.
Welcome screen
Back in October 2022, I experimented with adding a minimal welcome screen. I was initially hesitant, as I was already a fan of the welcome scratch buffer. In any case, I figured I'd eventually get tired of it and remove it. Well, it's enabled in my config still ;) My initial attachment to a landing scratch quickly faded. I'm only a C-x b
binding away from invoking ivy-switch-buffer to get me anywhere.
The great Emacs logo originally shared by u/pearcidar43.
Zones
I've been meaning to re-enable zones in my config. They always gave me a good tickle. I've already mentioned zone-nyan, but if you're new to zones, they kick off after a period of inactivity (similar to a screensaver).
Here's zone-pgm-rotate
in all its glory. Oh and it's built-in!
Coincidentally, I had a go at writing a basic zone a little while ago.
Config
Most of the items mentioned I pulled from my Emacs config's fe-ui.el. There's more there if you're interested.

shell-maker, a maker of Emacs shells
A few weeks ago, I wrote about an experiment to bring ChatGPT to Emacs as a shell. I was fairly new to both ChatGPT and building anything on top of comint. It was a fun exercise, which also generated some interest.
As mentioned in the previous post, I took inspiration in other Emacs packages (primarily ielm) to figure out what I needed from comint. Soon, I got ChatGPT working.
As I was looking at OpenAI API docs, I learned about DALL-E: "an AI system that can create realistic images and art from a description in natural language."
Like ChatGPT, they also offered an API to DALL-E, so I figured I may as well try to write a shell for that too… and I did.
There was quite a bit of code duplication between the two Emacs shells I had just written. At the same time, I started hearing from folks about integrating other tools, some cloud-based, some local, proprietary, open source.. There's Cody, invoke-ai, llama.cpp, alpaca.cpp, and the list continues to grow.
With that in mind, I set out to reduce the code duplication and consolidate into a reusable package. And so shell-maker
was born, a maker of Emacs shells.
shell-maker
's internals aren't too different from the code I had before. It's still powered by comint, but instead offers a reusable convenience wrapper.
It takes little code to implement a shell, like the sophisticated new greeter-shell
;)
(require 'shell-maker) (defvar greeter-shell--config (make-shell-maker-config :name "Greeter" :execute-command (lambda (command _history callback error-callback) (funcall callback (format "Hello \"%s\"" command) nil)))) (defun greeter-shell () "Start a Greeter shell." (interactive) (shell-maker-start greeter-shell--config))
shell-maker is available on GitHub and currently bundled with chatgpt-shell. If there's enough interest and usage, I may just break it out into its own package. For now, it's convenient to keep with chatgpt-shell
and dall-e-shell
.
If you plug shell-maker
into other tools, I'd love to hear about it.
Happy shell making!

A ChatGPT Emacs shell
UPDATE: chatgpt-shell
has evolved a bit and is now on MELPA.
I had been meaning to give ChatGPT a good try, preferably from Emacs. As an eshell fan, ChatGPT seemed like the perfect fit for a shell interface of sorts. With that in mind, I set out to wire ChatGPT with Emacs's general command interpreter (comint).
I had no previous experience building anything comint-related, so I figured I could just take a peek at an existing comint-derived mode to achieve a similar purpose. inferior-emacs-lisp-mode
(ielm) seemed to fit the bill just fine, so I borrowed quite a bit to assemble a basic shell experience.
From then on, it was mostly about sending each request over to the ChatGPT API to get a response. For now, I'm relying on curl to make each request. The invocation is fairly straightforward:
curl "https://api.openai.com/v1/chat/completions" \ -H "Authorization: Bearer YOUR_OPENAI_KEY" \ -H "Content-Type: application/json" \ -d "{ \"model\": \"gpt-3.5-turbo\", \"messages\": [{\"role\": \"user\", \"content\": \"YOUR PROMPT\"}] }"
There are two bits of information needed in each request. The API key, which you must get from OpenAI, and the prompt text itself (i.e. whatever you want ChatGPT to help you with). The results are not too shabby.
I've uploaded the code to GitHub as a tiny chatgpt-shell package. It's a little experimental and rough still, but hey, it does the job for now. Head over to github to take a look. The latest iteration handles multiline prompts (use C-j for newlines) and basic code highlighting.
Let's see where it all goes. Pull requests for improvements totally welcome ;-)
*scratch*
a new minimal org mode scratch area for iOS
While we already have lots of note-taking apps on iOS, I wanted a minimal *scratch*
area (à la Emacs), so I built one.
What's the use-case? You're on the go. Someone's telling you directions, or a phone number, name of a restaurant, anything really… you just need to write it down right now, quickly!
No time to create a new contact, a note, a file, or spend time on additional taps, bring up keyboard… You just want to write it somewhere with the least amount of friction.
Being an Emacs and org user, I had to sprinkle the app with basic markup support for headings, lists and checkboxes. Also, having a *scratch*
"buffer" on my iPhone gives me that warm emacsy fuzzy feeling :)
You can download *scratch*
from the App Store.
Find it useful? Please help me spread the word. Tell your friends.
Chicken Karaage recipe
Huge fan of Chicken Karaage, but never really made it at home until recently.
Dice the chicken
- 350 grams boneless chicken thighs
Dice the chicken up.
Marinade for 30 mins
- 1 tablespoon soy sauce (Kikkoman or similar)
- 1 tablespoon cooking Sake
- 2 tablespoons of grated ginger (include liquids)
- 1/2 teaspoon Mirin
Mix all ingredients into a ziploc bag. Add the diced chicken and let it marinade for 30 minutes in the fridge.
Pat dry
- Paper towels
After marinating, pat the chicken dry with paper towels and set aside.
Breading
- Potato starch
Ok, not quite breading since we're using potato starch but same goal. Sprinkle the chicken pieces and make sure they are fully coated with the starch.
Frying (1st round)
- Vegetable oil
- Paper towels
Heat up (roughly at 160°C) enough oil in a pan to cover the chicken pieces. Cook for about 3 minutes. The pieces don't have to be super golden at this point. There will be another round of frying for that.
Rest for 4 minutes
- Paper towels
Let the chicken rest on paper towels for about 4 minutes before frying again.
Frying (2nd round)
- Vegetable oil
- Paper towels
This time heat up the oil at roughly 200°C. This is a quick in-and-out action to make the chicken crispy. Cook for 30 seconds. Take out and set aside on some paper towels. Let it cool and it's ready to eat.
Dipping
- Kewpie mayo
- Sriracha sauce
This is totally optional, but I'm a fan of both Kewpie mayo and Sriracha sauce. You can dip your chicken in either or both!
Emacs: org-present in style
I had been meaning to check out David Wilson's System Crafters post detailing his presentations style achieved with the help of org-present and his own customizations. If you're looking for ways to present from Emacs itself, David's post is well worth a look.
org-present's spartan but effective approach resonated with me. David's touches bring the wonderfully stylish icing to the cake. I personally liked his practice of collapsing slide subheadings by default. This lead me to think about slide navigation in general…
There were two things I wanted to achieve:
- Easily jump between areas of interest. Subheadings, links, and code blocks would be a good start.
- Collapse all but the current top-level heading within the slide, as navigation focus changes.
A quick search for existing functions led me to org-next-visible-heading
, org-next-link
, and org-next-block
. While these make it easy to jump through jump between headings, links, org block on their own, I wanted to jump to whichever one of these is next (similar a web browser's tab behaviour). In a way, DWIM style.
I wrapped the existing functions to enable returning positions. This gave me ar/rg-next-visible-heading-pos
, ar/rg-next-link-pos
, and ar/rg-next-block-pos
respectively. Now that I can find out the next location of either of these items, I can subsequently glue the navigation logic in a function like ar/org-present-next-item
. To restore balance to the galaxy, I also added ar/org-present-previous-item
.
(defun ar/org-present-next-item (&optional backward) "Present and reveal next item." (interactive "P") ;; Beginning of slide, go to previous slide. (if (and backward (eq (point) (point-min))) (org-present-prev) (let* ((heading-pos (ar/org-next-visible-heading-pos backward)) (link-pos (ar/org-next-link-pos backward)) (block-pos (ar/org-next-block-pos backward)) (closest-pos (when (or heading-pos link-pos block-pos) (apply (if backward #'max #'min) (seq-filter #'identity (list heading-pos link-pos block-pos)))))) (if closest-pos (progn (cond ((eq heading-pos closest-pos) (goto-char heading-pos)) ((eq link-pos closest-pos) (goto-char link-pos)) ((eq block-pos closest-pos) (goto-char block-pos))) ;; Reveal relevant content. (cond ((> (org-current-level) 1) (ar/org-present-reveal-level2)) ((eq (org-current-level) 1) ;; At level 1. Collapse children. (org-overview) (org-show-entry) (org-show-children) (run-hook-with-args 'org-cycle-hook 'children)))) ;; End of slide, go to next slide. (org-present-next))))) (defun ar/org-present-previous-item () (interactive) (ar/org-present-next-item t)) (defun ar/org-next-visible-heading-pos (&optional backward) "Similar to `org-next-visible-heading' but for returning position. Set BACKWARD to search backwards." (save-excursion (let ((pos-before (point)) (pos-after (progn (org-next-visible-heading (if backward -1 1)) (point)))) (when (and pos-after (not (equal pos-before pos-after))) pos-after)))) (defun ar/org-next-link-pos (&optional backward) "Similar to `org-next-visible-heading' but for returning position. Set BACKWARD to search backwards." (save-excursion (let* ((inhibit-message t) (pos-before (point)) (pos-after (progn (org-next-link backward) (point)))) (when (and pos-after (or (and backward (> pos-before pos-after)) (and (not backward) (> pos-after pos-before)))) pos-after)))) (defun ar/org-next-block-pos (&optional backward) "Similar to `org-next-block' but for returning position. Set BACKWARD to search backwards." (save-excursion (when (and backward (org-babel-where-is-src-block-head)) (org-babel-goto-src-block-head)) (let ((pos-before (point)) (pos-after (ignore-errors (org-next-block 1 backward) (point)))) (when (and pos-after (not (equal pos-before pos-after))) ;; Place point inside block body. (goto-char (line-beginning-position 2)) (point))))) (defun ar/org-present-reveal-level2 () (interactive) (let ((loc (point)) (level (org-current-level)) (heading)) (ignore-errors (org-back-to-heading t)) (while (or (not level) (> level 2)) (setq level (org-up-heading-safe))) (setq heading (point)) (goto-char (point-min)) (org-overview) (org-show-entry) (org-show-children) (run-hook-with-args 'org-cycle-hook 'children) (goto-char heading) (org-show-subtree) (goto-char loc)))
Beware, this was a minimal effort (with redundant code, duplication, etc) and should likely be considered a proof of concept of sorts, but the results look promising. You can see a demo in action.
While this was a fun exercise, I can't help but think there must be a cleaner way of doing it or there are existing packages that already do this for you. If you do know, I'd love to know.
Future versions of this code will likely be updated in my Emacs org config.
Update
Removed a bunch of duplication and now rely primarily on existing org-next-visible-heading
, org-next-link
, and org-next-block
.
Emacs: insert and render SF symbols
About a week ago, I added an Emacs function to insert SF symbol names. This is specially useful for SwiftUI. I didn't bother too much with inserting symbols themselves since I hadn't figured out a way to render them for all buffers. That's now changed.
Christian Tietze and Alan Third both have useful posts in this space:
I'm currently using the following to render SF symbols in all buffers (macOS only):
;; Enable rendering SF symbols on macOS. (when (memq system-type '(darwin)) (set-fontset-font t nil "SF Pro Display" nil 'append))
Now that I can render SF symbols everywhere, I may be more included to use them to spif things up.
I've added sf-symbol-insert
to sf.el, let's see if usage sticks.
Emacs: Macro me some SF Symbols
For inserting SF Symbols in SwiftUI, I typically rely on Apple's SF Symbols app to browse the symbols's catalog. Once I find a symbol I'm happy with, I copy its name and paste it into my Swift source. This works fairly well.
With Christian Tietze recently posting how he rendered SF Symbols in Emacs, I figured there may be a way to shift the above workflow to rely on Emacs completion instead. While I initially went down a rabbit hole to programmatically extract SF symbols (via something like SFSafeSymbols), I took a step back to rethink the strategy.
From the SF Symbols app, one can select multiple symbols and copy/paste either the symbols themselves or their respective names. The catch is you can only copy disjointed data. That is, you can copy the symbols or their names, but not both in one go. Let's take a look at what the disjointed data looks like. I've pasted both under separate sections in an Emacs buffer.
If I could rejoin these two sets, I would have a lookup table I could easily invoke from Emacs.
There are roughly 4500 symbols, so copying, pasting, along with text manipulation isn't manually feasible. Lucky for us, an Emacs keyboard macro is the perfect hammer for this nail. You can see the macro in action below.
This looks fairly magical (and it is), but when you break it down into its building blocks, it's nothing more than recording your keystrokes and replaying them. Starting with the cursor at the beginning of square.and.arrow.up
, these are the keystrokes we'd need to record:
- C-s
- iseach-forward to search for a character and jump to it
- =
- insert
=
so we jump to= Symbols =
- <return>
- runs isearch-exit since we're done jumping.
- C-n
next-line
.- C-a
beginning-of-line
.- C-SPC
set-mark-command
to activate the region.- C-f
forward-char
to select symbol.- C-w
kill-ring-save
to cut/kill the symbol.- C-u C-<space>
set-mark-command
(with prefix) to jump back to where we started before searching.- C-y
yank
to yank/paste the symbol.- C-<space>
set-mark-command
to activate the region.- C-e
end-of-line
to select the entire line.- "
- As a smartparens user, inserting quote with region places quotes around selection.
- C-n
next-line
.- C-a
beginning-of-line
. We are now at a strategic location where we can replay the above commands.
To start/end recording and executing keyboard macros, use:
- C-x (
- kmacro-start-macro
- C-x )
- kmacro-end-macro
- C-x e
- kmacro-end-and-call-macro runs your macro. Press
e
immediately after to execute again. - C-u 0 C-x e
- kmacro-end-and-call-macro (with zero prefix) repeat until there is an error.
Our previous example ran on a handful of SF symbols. Let's bring out the big guns and run on the entire dataset. This time, we'll run the entire flow, including macro creation and executing until there is an error (i.e. process the whole lot).
Now that we have our data joined, we can feed it to the humble completing-read.
It's worth highlighting that to render SF Symbols in Emacs, we must propertize our text with one of the macOS SF fonts, for example "SF Pro".
With all the pieces in place, let's use our new function to insert SF symbol names in a SwiftUI snippet. Since we're using completing-read
we can fuzzy search our lookups with our favorite completion frameworks (in my case via ivy).
While this post is macOS-specific, it gives a taste of how powerful Emacs keyboard macros can be. Be sure to check out Emacs Rocks! Episode 05: Macros in style and Keyboard Macros are Misunderstood - Mastering Emacs. For those that dabble in elisp, you can appreciate how handy completing-read is with very little code.
The full source to sf-symbol-insert-name is available in my Emacs config repo. The function is fairly bare bones and has had fairly little testing. Patches totally welcome.
Update
There is some redundancy in the snippet I had forgotten to remove. Either way, latest version at sf.el.
Emacs: ffmpeg and macOS aliasing commands
On a recent mastodon post, Chris Spackman mentioned he uses Emacs to save ffmpeg commands he's figured out for later usage. Emacs is great for this kind of thing. I've tried different approaches over time and eventually landed on dwim-shell-command, a small package I wrote. Like Chris, I also wanted a way to invoke magical incantations of known shell commands without having to remember all the details.
Chris's post reminded me of a few use-cases I'd been meaning to add DWIM shell commands for.
ffmpeg
- Trimming seconds from videos
dwim-shell-commands-video-trim-beginning
using:ffmpeg -i '<<f>>' -y -ss <<Seconds:5>> -c:v copy -c:a copy '<<fne>>_trimmed.<<e>>'
dwim-shell-commands-video-trim-end
using:ffmpeg -sseof -<<Seconds:5>> -i '<<f>>' -y -c:v copy -c:a copy '<<fne>>_trimmed.<<e>>'
Side-node: The
<<Seconds:5>>
placeholder is recognized as a query, so Emacs will prompt you for a numeric value.
- Extracting audio from videos
dwim-shell-commands-video-to-mp3
using:ffmpeg -i '<<f>>' -vn -ab 128k -ar 44100 -y '<<fne>>.mp3'
With these new dwim shell commands added, I can easily apply them one after the other. No need to remember command details.
macOS aliases
After rebuilding Emacs via the wonderful emacs-plus, I recently broke my existing /Applications/Emacs.app
alias. No biggie, one can easily add a new one alias from macOS Finder, but I've been wanting to do it from Emacs. Turns out there's a bit of AppleScript we can turn into a more memorale command like dwim-shell-commands-macos-make-finder-alias
:
osascript -e 'tell application \"Finder\" to make alias file to POSIX file \"<<f>>\" at POSIX file \"%s\"'
It's highly unlikely I'll remember the AppleScript snippet (are there better ways?), but I'll easily find and invoke my new command with fuzzy searching:
Included in dwim-shell-command
All of these are now included in dwim-shell-commands.el, which you can optionally load after installing dwim-shell-command from MELPA.
Emacs: Context-aware yasnippets
Back in 2020, I wrote a semi-automatic yasnippet to generate Swift initializers. I say semi-automatic because it could have been a little smarter. While it helped generate some of the code, what I really wanted was full context-aware generation. The Swift struct already had a few properties defined, so a smarter yasnippet should have been able to use this info for code generation.
With an extra push, we could have written a smarter yasnippet, but it may require a fair bit of parsing logic. Fast forward to today, and bringing context-awareness seems like the right match for Tree-sitter. While Tree-sitter can enable faster and more reliable syntax-highlighting in our beloved text editor, it can also power smarter tools. It does so by exposing a semantic snapshot of our source code using a syntax tree.
Let's see how we can use Tree-sitter to realise our original yasnippet vision. We'll start with the same struct snippet we used back in 2020. The goal is to generate an initializer using the existing definitions.
struct Coordinate { public let x: Int public let y: Int public let z: Int }
While Emacs will will soon ship its own Tree-sitter integration, I've opted to try out the emacs-tree-sitter package as Swift support is currently included in tree-sitter-langs.
I have much to learn much about Tree-sitter syntax trees, but the package ships with a handy tool to dump the tree via tree-sitter-debug-mode
.
With a syntax tree in mind, one can craft a query to semantically extract parts of the code. In our case, we want property names and types.
I've yet to get acquainted with Tree-sitter's query syntax, but the package also ships with another handy tool that helps view query results via tree-sitter-query-builder
.
The following query extracts all the let properties
in file. You can see the builder in action above, highlighting our query results.
(struct_declaration (constant_declaration (identifier) @name (type) @value))
If we want to be more thorough, we should likely cater for classes, vars, int/string literals, etc. so the query needs to be extended as follows. I'm sure it can be written differently, but for now, it does the job.
(struct_declaration (variable_declaration (identifier) @name (type) @type)) (struct_declaration (variable_declaration (identifier) @name (string) @value)) (struct_declaration (variable_declaration (identifier) @name (number) @value)) (struct_declaration (constant_declaration (identifier) @name (type) @value)) (struct_declaration (constant_declaration (identifier) @name (string) @value)) (struct_declaration (constant_declaration (identifier) @name (number) @value)) (class_declaration (variable_declaration (identifier) @name (type) @type)) (class_declaration (variable_declaration (identifier) @name (string) @value)) (class_declaration (variable_declaration (identifier) @name (number) @value)) (class_declaration (constant_declaration (identifier) @name (type) @type)) (class_declaration (constant_declaration (identifier) @name (string) @value)) (class_declaration (constant_declaration (identifier) @name (number) @value))
Now that we got our Tree-sitter query sorted, let's write a little elisp to extract the info we need from the generated tree. We'll write a swift-class-or-struct-vars-at-point
function to extract the struct (or class) at point and subsequently filter its property names/types using our query. To simplify the result, we'll return a list of alists.
(defun swift-class-or-struct-vars-at-point () "Return a list of class or struct vars in the form '(((name . \"foo\") (type . \"Foo\")))." (cl-assert (seq-contains local-minor-modes 'tree-sitter-mode) "tree-sitter-mode not enabled") (let* ((node (or (tree-sitter-node-at-point 'struct_declaration) (tree-sitter-node-at-point 'class_declaration))) (vars) (var)) (unless node (error "Neither in class nor struct")) (mapc (lambda (item) (cond ((eq 'identifier (tsc-node-type (cdr item))) (when var (setq vars (append vars (list var)))) (setq var (list (cons 'name (tsc-node-text (cdr item)))))) ((eq 'type (tsc-node-type (cdr item))) (setq var (map-insert var 'type (tsc-node-text (cdr item))))) ((eq 'string (tsc-node-type (cdr item))) (setq var (map-insert var 'type "String"))) ((eq 'number (tsc-node-type (cdr item))) (setq var (map-insert var 'type "Int"))) (t (message "%s" (tsc-node-type (cdr item)))))) (tsc-query-captures (tsc-make-query tree-sitter-language "(struct_declaration (variable_declaration (identifier) @name (type) @type)) (struct_declaration (variable_declaration (identifier) @name (string) @value)) (struct_declaration (variable_declaration (identifier) @name (number) @value)) (struct_declaration (constant_declaration (identifier) @name (type) @value)) (struct_declaration (constant_declaration (identifier) @name (string) @value)) (struct_declaration (constant_declaration (identifier) @name (number) @value)) (class_declaration (variable_declaration (identifier) @name (type) @type)) (class_declaration (variable_declaration (identifier) @name (string) @value)) (class_declaration (variable_declaration (identifier) @name (number) @value)) (class_declaration (constant_declaration (identifier) @name (type) @type)) (class_declaration (constant_declaration (identifier) @name (string) @value)) (class_declaration (constant_declaration (identifier) @name (number) @value))") node nil)) (when var (setq vars (append vars (list var)))) vars))
(((type . "Int") (name . "x")) ((type . "Int") (name . "y")) ((type . "Int") (name . "z")))
Finally, we write a function to generate a Swift initializer from our property list.
(defun swift-class-or-struct-initializer-text (vars) "Generate a Swift initializer from property VARS." (cl-assert (seq-contains local-minor-modes 'tree-sitter-mode) "tree-sitter-mode not enabled") (format (string-trim " init(%s) { %s }") (seq-reduce (lambda (reduced var) (format "%s%s%s: %s" reduced (if (string-empty-p reduced) "" ", ") (map-elt var 'name) (map-elt var 'type))) vars "") (string-join (mapcar (lambda (var) (format "self.%s = %s" (map-elt var 'name) (map-elt var 'name))) vars) "\n ")))
init(x: Int, y: Int, z: Int) { self.x = x self.y = y self.z = z }
We're so close now. All we need is a simple way invoke our code generator. We can use yasnippet for that, making init
our expandable keyword.
# -*- mode: snippet -*- # name: init all # key: init # -- `(swift-class-or-struct-initializer-text (swift-class-or-struct-vars-at-point))`
And with all that, we've got our yasnippet vision accomplished!
Be sure to check out this year's relevant EmacsConf talk: Tree-sitter beyond syntax highlighting.
All code is now pushed to my config repo. By the way, I'm not super knowledgable of neither yasnippet nor Tree-sitter. Improvements are totally welcome. Please reach out on the Fediverse if you have suggestions!
Update
Josh Caswell kindly pointed out a couple of interesting items:
- tree-sitter-langs's Swift grammar is fairly outdated/incomplete.
- There are more up-to-date Swift grammar implementations currently available:
- tree-sitter-swifter (by Josh Caswell himself)
- tree-sitter-swift (by Alex Pinkus)
Emacs: quickly killing processes
Every so often, I need to kill the odd unresponsive process. While I really like proced
(check out Mickey Petersen's article), I somehow find myself using macOS's Activity Monitor to this purpose. Kinda odd, considering I prefer to do these kinds of things from Emacs.
What I'd really like is a way to quickly fuzzy search a list of active processes and choose the unresponsive culprid, using my preferred completion frontend (in my case ivy).
The function below gives us a fuzzy-searchable process utility. While we could use ivy-read
directly in our implementation, we're better of using completing-read to remain compatible with other completion frameworks. I'm a big fan of the humble completing-read
. You feed it a list of candidates and it prompts users to pick one.
To build our process list, we can lean on proced
's own source: proced-process-attributes
. We transform its output to an alist, formatting the visible keys to contain the process id, owner, command name, and the command line which invoked the process. Once a process is chosen, we can send a kill signal using signal-process dwim-shell-command and our job is done.
(require 'dwim-shell-command) (require 'map) (require 'proced) (require 'seq) (defun dwim-shell-commands-kill-process () "Select and kill process." (interactive) (let* ((pid-width 5) (comm-width 25) (user-width 10) (processes (proced-process-attributes)) (candidates (mapcar (lambda (attributes) (let* ((process (cdr attributes)) (pid (format (format "%%%ds" pid-width) (map-elt process 'pid))) (user (format (format "%%-%ds" user-width) (truncate-string-to-width (map-elt process 'user) user-width nil nil t))) (comm (format (format "%%-%ds" comm-width) (truncate-string-to-width (map-elt process 'comm) comm-width nil nil t))) (args-width (- (window-width) (+ pid-width user-width comm-width 3))) (args (map-elt process 'args))) (cons (if args (format "%s %s %s %s" pid user comm (truncate-string-to-width args args-width nil nil t)) (format "%s %s %s" pid user comm)) process))) processes)) (selection (map-elt candidates (completing-read "kill process: " (seq-sort (lambda (p1 p2) (string-lessp (nth 2 (split-string (string-trim (car p1)))) (nth 2 (split-string (string-trim (car p2)))))) candidates) nil t))) (prompt-title (format "%s %s %s" (map-elt selection 'pid) (map-elt selection 'user) (map-elt selection 'comm)))) (when (y-or-n-p (format "Kill? %s" prompt-title)) (dwim-shell-command-on-marked-files (format "Kill %s" prompt-title) (format "kill -9 %d" (map-elt selection 'pid)) :utils "kill" :error-autofocus t :silent-success t))))
I've pushed dwim-shell-commands-kill-process
to my config dwim-shell-commands.el. Got suggestions? Alternatives? Lemme know.
Update
I've moved dwim-shell-commands-kill-process
from my Emacs config to dwim-shell-commands.el. A few advantages:
- Killing processes is now async.
- Should anything go wrong, an error message is now accessible.
- You can easily install via MELPA.
If you prefer the previous version (without a dependency on dwim-shell-command), have a look at the initial commit.
Hey Emacs, change the default macOS app for…
A few weeks ago, I added an "open with" command to dwim-shell-commands.el. It's pretty handy for opening files using an external app (ie. not Emacs) other than the default macOS one.
dwim-shell-commands-macos-open-with
and dwim-shell-commands-open-externally
are typically enough for me to handle opening files outside of Emacs. But every now and then I'd like to change the default macOS app associated with specific file types. Now this isn't particularly challenging in macOS, but it does require a little navigating to get to the right place to change this default setting.
Back in March 2020, I tweeted about duti: a command-line utility capable of setting default applications for various document types on macOS. While I liked the ability to change default apps from the command-line, the habit never quite stuck.
Fast forward to 2022. I've been revisiting lots of my command-line usages (specially those that never stuck) and making them more accessible from Emacs via dwim-shell-command. I seldom change default apps on macOS, so my brain forgets about duti
itself, let alone its arguments, order, etc. But with a dwim shell command like dwim-shell-commands-macos-set-default-app
, I can easily invoke the command via swiper's counsel-M-x
fuzzy terms: "dwim set".
As an added bonus, I get to reuse dwim-shell-commands--macos-apps
from "open with" to quickly pick the new default app, making the whole experience pretty snappy.
(defun dwim-shell-commands-macos-set-default-app () "Set default app for file(s)." (interactive) (let* ((apps (dwim-shell-commands-macos-apps)) (selection (progn (cl-assert apps nil "No apps found") (completing-read "Set default app: " apps nil t)))) (dwim-shell-command-on-marked-files "Set default app" (format "duti -s \"%s\" '<<e>>' all" (string-trim (shell-command-to-string (format "defaults read '%s/Contents/Info.plist' CFBundleIdentifier" (map-elt apps selection))))) :silent-success t :no-progress t :utils "duti"))) (defun dwim-shell-commands--macos-apps () "Return alist of macOS apps (\"Emacs\" . \"/Applications/Emacs.app\")." (mapcar (lambda (path) (cons (file-name-base path) path)) (seq-sort #'string-lessp (seq-mapcat (lambda (paths) (directory-files-recursively paths "\\.app$" t (lambda (path) (not (string-suffix-p ".app" path))))) '("/Applications" "~/Applications" "/System/Applications")))))
As usual, I've added dwim-shell-commands-macos-set-default-app
to dwim-shell-commands.el, which you can install via MELPA.
Did you find this tiny integration useful? Check out Hey Emacs, where did I take that photo?
Hey Emacs, where did I take that photo?
I was recently browsing through an old archive of holiday photos (from dired of course). I wanted to know where the photo was taken, which got me interested in extracting Exif metadata.
Luckily the exiftool command line utility does the heavy lifting when it comes to extracting metadata. Since I want it quickly accessible from Emacs (in either dired or current buffer), a tiny elisp snippet would give me just that (via dwim-shell-command).
(defun dwim-shell-commands-image-exif-metadata () "View EXIF metadata in image(s)." (interactive) (dwim-shell-command-on-marked-files "View EXIF" "exiftool '<<f>>'" :utils "exiftool"))
The above makes all Exif metadata easily accessible, including the photo's GPS coordinates. But I haven’t quite answered the original question. Where did I take the photo? I now know the coordinates, but I can’t realistically deduce neither the country nor city unless I manually feed these values to a reverse geocoding service like OpenStreetMap. Manually you say? This is Emacs, so we can throw more elisp glue at the problem, mixed in with a little shell script, and presto! We've now automated the process of extracting metadata, reverse geocoding, and displaying the photo's address in the minibuffer. Pretty nifty.
(defun dwim-shell-commands-image-reverse-geocode-location () "Reverse geocode image(s) location." (interactive) (dwim-shell-command-on-marked-files "Reverse geocode" "lat=\"$(exiftool -csv -n -gpslatitude -gpslongitude '<<f>>' | tail -n 1 | cut -s -d',' -f2-2)\" if [ -z \"$lat\" ]; then echo \"no latitude\" exit 1 fi lon=\"$(exiftool -csv -n -gpslatitude -gpslongitude '<<f>>' | tail -n 1 | cut -s -d',' -f3-3)\" if [ -z \"$lon\" ]; then echo \"no longitude\" exit 1 fi json=$(curl \"https://nominatim.openstreetmap.org/reverse?format=json&accept-language=en&lat=${lat}&lon=${lon}&zoom=18&addressdetails=1\") echo \"json_start $json json_end\"" :utils '("exiftool" "curl") :silent-success t :error-autofocus t :on-completion (lambda (buffer) (with-current-buffer buffer (goto-char (point-min)) (let ((matches '())) (while (re-search-forward "^json_start\\(.*?\\)json_end" nil t) (push (match-string 1) matches)) (message "%s" (string-join (seq-map (lambda (json) (map-elt (json-parse-string json :object-type 'alist) 'display_name)) matches) "\n"))) (kill-buffer buffer)))))
Displaying the photo's address in the minibuffer is indeed pretty nifty, but what if I’d like to drop a pin in a map for further exploration? This is actually simpler, as there's no need for reverse geocoding. Following a similar recipe, we merely construct an OpenStreetMap URL and open it in our favourite browser.
(defun dwim-shell-commands-image-browse-location () "Open image(s) location in browser." (interactive) (dwim-shell-command-on-marked-files "Browse location" "lat=\"$(exiftool -csv -n -gpslatitude -gpslongitude '<<f>>' | tail -n 1 | cut -s -d',' -f2-2)\" if [ -z \"$lat\" ]; then echo \"no latitude\" exit 1 fi lon=\"$(exiftool -csv -n -gpslatitude -gpslongitude '<<f>>' | tail -n 1 | cut -s -d',' -f3-3)\" if [ -z \"$lon\" ]; then echo \"no longitude\" exit 1 fi if [[ $OSTYPE == darwin* ]]; then open \"http://www.openstreetmap.org/?mlat=${lat}&mlon=${lon}&layers=C\" else xdg-open \"http://www.openstreetmap.org/?mlat=${lat}&mlon=${lon}&layers=C\" fi" :utils "exiftool" :error-autofocus t :silent-success t))
Got suggestions? Improvements? All three functions are now included in dwim-shell-commands.el as part of dwim-shell-command. Pull requests totally welcome ;)
Emacs: A welcoming experiment
The *scratch*
buffer is the first thing I see when I launch an Emacs session. Coupled with persistent-scratch, it's served me well over the years. I gotta say though, my scratch buffer accumulates random bits and often becomes a little messy. It's not the most visually appealing landing buffer when launching Emacs. But who cares, I'm only a C-x b
binding away from invoking ivy-switch-buffer
to get me wherever I need to be. It's powered by ivy-use-virtual-buffers
, which remembers recent files across sessions.
Having said all of this, I recently ran into u/pearcidar43's post showcasing a wonderful Emacs banner. Lucky for us, they shared the image, so I got curious about building a minimal welcome buffer of sorts. Nothing fancy, the only requirements being to load quickly and enable me to get on with my C-x b
ritual. Throw in a little bonus to exit quickly by pressing just q
if I so desire.
I didn't know a whole lot on how to go about it, so I took a peak at emacs-dashboard for inspiration. Turns out, I needed little code to get
the desired effect in my early-init.el
:
(defun ar/show-welcome-buffer () "Show *Welcome* buffer." (with-current-buffer (get-buffer-create "*Welcome*") (setq truncate-lines t) (let* ((buffer-read-only) (image-path "~/.emacs.d/emacs.png") (image (create-image image-path)) (size (image-size image)) (height (cdr size)) (width (car size)) (top-margin (floor (/ (- (window-height) height) 2))) (left-margin (floor (/ (- (window-width) width) 2))) (prompt-title "Welcome to Emacs!")) (erase-buffer) (setq mode-line-format nil) (goto-char (point-min)) (insert (make-string top-margin ?\n )) (insert (make-string left-margin ?\ )) (insert-image image) (insert "\n\n\n") (insert (make-string (floor (/ (- (window-width) (string-width prompt-title)) 2)) ?\ )) (insert prompt-title)) (setq cursor-type nil) (read-only-mode +1) (switch-to-buffer (current-buffer)) (local-set-key (kbd "q") 'kill-this-buffer))) (setq initial-scratch-message nil) (setq inhibit-startup-screen t) (when (< (length command-line-args) 2) (add-hook 'emacs-startup-hook (lambda () (when (display-graphic-p) (ar/show-welcome-buffer)))))
This being Emacs, I can bend it as far as needed. In my case, I didn't need much, so I can probably stop here. It was a fun experiment. I'll even try using it for a little while and see if it sticks. I'm sure there's plenty more that could be handled (edge cases, resizes, etc.), but if you want something more established, consider something like emacs-dashboard instead. I haven't used it myself, but is pretty popular.
Emacs: Open with macOS app
On a recent Reddit comment, tdstoff7 asked if I had considered writing an "Open with" DWIM shell command for those times one would like to open a file externally using an app other than the default. I hadn't, but nice idea.
Take images as an example. Though Emacs can display them quickly, I also open images externally using the default app (Preview in my case). But then there are those times when I'd like to open with a different app for editing (maybe something like GIMP). It'd be nice to quickly choose which app to open with.
There isn't much to the code. Get a list of apps, ask user to pick one (via completing-read), and launch the external app via dwim-shell-command-on-marked-files
.
There's likely a better way of getting a list of available apps (happy to take suggestions), but searching in "/Applications" "~/Applications" and "/System/Applications" does the job for now.
(defun dwim-shell-commands-macos-open-with () "Convert all marked images to jpg(s)." (interactive) (let* ((apps (seq-sort #'string-lessp (seq-mapcat (lambda (paths) (directory-files-recursively paths "\\.app$" t (lambda (path) (not (string-suffix-p ".app" path))))) '("/Applications" "~/Applications" "/System/Applications")))) (selection (progn (cl-assert apps nil "No apps found") (completing-read "Open with: " (mapcar (lambda (path) (propertize (file-name-base path) 'path path)) apps))))) (dwim-shell-command-on-marked-files "Open with" (format "open -a '%s' '<<*>>'" (get-text-property 0 'path selection)) :silent-success t :no-progress t :utils "open")))
dwim-shell-commands-macos-open-with
is now included in dwim-shell-command, available on melpa. What other uses can you find for it?
Improving on Emacs macOS sharing
A quick follow-up to Emacs: macOS sharing (DWIM style)… Though functional, the implementation had a couple of drawbacks.
Tohiko noticed fullscreen wasn't working at all while Calvin proposed enumeration for tighter Emacs integration.
Calvin's suggestion enables using completing-read to pick the sharing service. This makes the integration feel more at home. As a bonus, it also enables sharing from fullscreen Emacs.
As an ivy user, you can see a vertical list of sharing services.
Here's the new snippet, now pushed to dwim-shell-commands.el:
(defun dwim-shell-commands--macos-sharing-services () "Return a list of sharing services." (let* ((source (format "import AppKit NSSharingService.sharingServices(forItems: [ %s ]).forEach { print(\"\\($0.prompt-title)\") }" (string-join (mapcar (lambda (file) (format "URL(fileURLWithPath: \"%s\")" file)) (dwim-shell-command--files)) ", "))) (services (split-string (string-trim (shell-command-to-string (format "echo '%s' | swift -" source))) "\n"))) (when (seq-empty-p services) (error "No sharing services available")) services)) (defun dwim-shell-commands-macos-share () "Share selected files from macOS." (interactive) (let* ((services (dwim-shell-commands--macos-sharing-services)) (service-name (completing-read "Share via: " services)) (selection (seq-position services service-name #'string-equal))) (dwim-shell-command-on-marked-files "Share" (format "import AppKit _ = NSApplication.shared NSApp.setActivationPolicy(.regular) class MyWindow: NSWindow, NSSharingServiceDelegate { func sharingService( _ sharingService: NSSharingService, didShareItems items: [Any] ) { NSApplication.shared.terminate(nil) } func sharingService( _ sharingService: NSSharingService, didFailToShareItems items: [Any], error: Error ) { let error = error as NSError if error.domain == NSCocoaErrorDomain && error.code == NSUserCancelledError { NSApplication.shared.terminate(nil) } exit(1) } } let window = MyWindow( contentRect: NSRect(x: 0, y: 0, width: 0, height: 0), styleMask: [], backing: .buffered, defer: false) let services = NSSharingService.sharingServices(forItems: [\"<<*>>\"].map{URL(fileURLWithPath:$0)}) let service = services[%s] service.delegate = window service.perform(withItems: [\"<<*>>\"].map{URL(fileURLWithPath:$0)}) NSApp.run()" selection) :silent-success t :shell-pipe "swift -" :join-separator ", " :no-progress t :utils "swift")))

Emacs: Reveal in macOS Finder (DWIM style)
Just the other day, Graham Voysey filed an escaping bug against dwim-shell-command. Once he verified the the fix, he also posted two uses of dwim-shell-command-on-marked-files
. I've made some small tweaks, but here's the gist of it:
(defun dwim-shell-commands-feh-marked-files () "View all marked files with feh." (interactive) (dwim-shell-command-on-marked-files "View with feh" "feh --auto-zoom --scale-down '<<*>>'" :silent-success t :utils "feh")) (defun dwim-shell-commands-dragon-marked-files () "Share all marked files with dragon." (interactive) (dwim-shell-command-on-marked-files "View with dragon" "dragon --on-top '<<*>>'" :silent-success t :utils "dragon"))
I love seeing what others get up to by using dwim-shell-command
. Are there new magical command-line utilities out there I don't know about? In this instance, I got to learn about feh and dragon.
feh is a no-frills image viewer for console users while dragon is a simple drag-and-drop source/sink for X or Wayland. Both utilities are great uses of dwim-shell-command
, enabling a seamless transition from Emacs to the outside world. These days I'm rarely on a linux box, so I was keen to ensure macOS had these cases covered.
Preview is a solid macOS equivalent to feh. Preview
is already macOS's default image viewer. A simple open '<<f>>'
would do the job, but if we'd like to make this command more portable, we can accomodate as follows:
(defun dwim-shell-commands-open-externally () "Open file(s) externally." (interactive) (dwim-shell-command-on-marked-files "Open externally" (if (eq system-type 'darwin) "open '<<f>>'" "xdg-open '<<f>>'") :silent-success t :utils "open"))
Special mention goes to Bozhidar Batsov's crux which achieves similar functionality via crux-open-with
. crux provides a bunch of other useful functions. Some of my favourites being crux-duplicate-current-line-or-region
, crux-transpose-windows
, crux-delete-file-and-buffer
, and crux-rename-buffer-and-file
, but I digress.
Moving on to a dragon equivalent on macOS, I thought I had it covered via reveal-in-osx-finder or reveal-in-folder. Turns out, neither of these reveal multiple dired-selected files within Finder. At first, I thought this could be easily achieved by passing additional flags/params to macOS's open
command, but it doesn't seem to be the case. Having said that, this Stack Overflow post, has a solution in Objective-C, which is where things got a little more interesting. You see, back in July I added multi-language support to dwim-shell-command and while it highlighted language flexibility, I hadn't yet taken advantage of this feature myself. That is, until today.
The Objective-C snippet from the Stack Overflow post can be written as a Swift one-liner. Ok I lie. It's actually two lines, counting the import, but you can see that this multi-language Emacs transition/integration is pretty easy to add.
(defun dwim-shell-commands-macos-reveal-in-finder () "Reveal selected files in macOS Finder." (interactive) (dwim-shell-command-on-marked-files "Reveal in Finder" "import AppKit NSWorkspace.shared.activateFileViewerSelecting([\"<<*>>\"].map{URL(fileURLWithPath:$0)})" :join-separator ", " :silent-success t :shell-pipe "swift -"))
<<*>>
is the centrepiece of the snippet above. It gets instantiated with a list of files joined using the ", "
separator.
NSWorkspace.shared.activateFileViewerSelecting(["/path/to/file1", "/path/to/file2"].map { URL(fileURLWithPath: $0) })
The proof of the pudding is of course in the eating, so ummm let's show it in action:
I should mention the webp animation above was also created using my trusty dwim-shell-commands-video-to-webp
also backed by dwim-shell-command.
(defun dwim-shell-commands-video-to-webp () "Convert all marked videos to webp(s)." (interactive) (dwim-shell-command-on-marked-files "Convert to webp" "ffmpeg -i '<<f>>' -vcodec libwebp -filter:v fps=fps=10 -compression_level 3 -lossless 1 -loop 0 -preset default -an -vsync 0 '<<fne>>'.webp" :utils "ffmpeg"))
dwim-shell-command is available on melpa. What other uses can you find for it?
UPDATE: Most DWIM shell commands I use are available as part of dwim-shell-commands.el. See dwim-shell-command

Plain Org v1.5 released
If you haven't heard of Plain Org, it gives you access to org files on iOS while away from your beloved Emacs.
Hadn't had time to post, but v1.5 has been available on the App Store for a couple of weeks now. The update is mostly a bugfix release, primarily addressing inline editing issues that appeared on iOS 16, along with a few other changes:
- Render form feeds at end of headings at all times.
- Fixes new files not recognized by org-roam.

dwim-shell-command usages: pdftotext and scp
dwim-shell-command is a little Emacs package I wrote to enable crafting more reusable shell commands. I intended to use it as an async-shell-command alternative (and I do these days). The more surprising win was bringing lots of command-line utilities (sometimes with complicated invocations) and making them quickly accessible. I no longer need to remember their respective parameters, order, flags, etc.
I've migrated most one-liners and scripts I had to dwim-shell-command equivalents. They are available at dwim-shell-commands.el. Having said that, it's great to discover new usages from dwim-shell-command
users.
Take u/TiMueller's Reddit comment, showcasing pdftotext. Neat utility I was unaware of. It does as it says on the tin and converts a pdf to text. Can be easily saved to your accessible repertoire with:
(defun dwim-shell-commands-pdf-to-txt () "Convert pdf to txt." (interactive) (dwim-shell-command-on-marked-files "pdf to txt" "pdftotext -layout '<<f>>' '<<fne>>.txt'" :utils "pdftotext"))
tareefdev wanted a quick command to secure copy remote files to a local directory. Though this use-case is already covered by Tramp, I suspect a DWIM command would make it a little more convenient (async by default). However, Tramp paths aren't usable from the shell unless we massage them a little. We can use dwim-shell-command-on-marked-files
's :post-process-template
to drop the "/ssh:" prefix.
(defun dwim-shell-commands-copy-remote-to-downloads () (interactive) (dwim-shell-command-on-marked-files "Copy remote to local Downloads" "scp '<<f>>' ~/Downloads/" :utils "scp" :post-process-template (lambda (script file) ;; Tramp file path start with "/ssh:". Drop it. (string-replace file (string-remove-prefix "/ssh:" file) script))))
dwim-shell-command is available on MELPA (531 downloads as of 2022-10-01).
$ rm Important.txt (uh oh!)
Setting Emacs up to use your system trash can potentially save your bacon if you mistakenly delete a file, say from dired.
Unsurprisingly, the trash safety net also extends to other Emacs areas. For example, discarding files from Magit (via magit-discard
) becomes a recoverable operation. As an eshell user, the trash can also help you recover from rm
blunders.
You can enable macOS system trash in Emacs by setting trash-directory
along with defining system-move-file-to-trash
:
(setq trash-directory "~/.Trash") ;; See `trash-directory' as it requires defining `system-move-file-to-trash'. (defun system-move-file-to-trash (file) "Use \"trash\" to move FILE to the system trash." (cl-assert (executable-find "trash") nil "'trash' must be installed. Needs \"brew install trash\"") (call-process "trash" nil 0 nil "-F" file))
Cycling through window layouts (revisited)
Last year, I wrote a little script to cycle through window layouts via Hammerspoon. The cycling set I chose didn't stick, so here's another go.
function reframeFocusedWindow() local win = hs.window.focusedWindow() local maximizedFrame = win:screen():frame() maximizedFrame.x = maximizedFrame.x + 15 maximizedFrame.y = maximizedFrame.y + 15 maximizedFrame.w = maximizedFrame.w - 30 maximizedFrame.h = maximizedFrame.h - 30 local leftFrame = win:screen():frame() leftFrame.x = leftFrame.x + 15 leftFrame.y = leftFrame.y + 15 leftFrame.w = leftFrame.w / 2 - 15 leftFrame.h = leftFrame.h - 30 local rightFrame = win:screen():frame() rightFrame.x = rightFrame.w / 2 rightFrame.y = rightFrame.y + 15 rightFrame.w = rightFrame.w / 2 - 15 rightFrame.h = rightFrame.h - 30 if win:frame() == maximizedFrame then win:setFrame(leftFrame) return end if win:frame() == leftFrame then win:setFrame(rightFrame) return end win:setFrame(maximizedFrame) end hs.hotkey.bind({"alt"}, "F", reframeFocusedWindow)
Looping through layouts is done with a global key-binding of option f
or, if familiar with a macOS keyboard, ⌥ f
.
For those unfamiliar with Hammerspoon… If you're a tinkerer and a macOS user, you'd love Hammerspoon. Like elisp gluing all things Emacs, Hammerspoon uses Lua to glue all things macOS. For example, here's a stint at writing a narrowing utility for macOS using chooser.
dwim-shell-command with template prompts
Somewhat recently, I wanted to quickly create an empty/transparent png file. ImageMagick's convert has you covered here. Say you want a transparent 200x400 image, you can get it with:
convert -verbose -size 200x400 xc:none empty200x400.png
Great, I now know the one-liner for it. But because I'm in the mood of saving these as seamless command-line utils, I figured I should save the dwim-shell-command equivalent.
I wanted configurable image dimensions, so I used read-number together with format to create the templated command and fed it to dwim-shell-command-on-marked-files
. Job done:
(defun dwim-shell-commands-make-transparent-png () "Create a transparent png." (interactive) (let ((width (read-number "Width: " 200)) (height (read-number "Height: " 200))) (dwim-shell-command-on-marked-files "Create transparent png" (format "convert -verbose -size %dx%d xc:none '<<empty%dx%d.png(u)>>'" width height width height) :utils "convert")))
The resulting dwim-shell-commands-make-transparent-png
is fairly simple, but dwim-shell-command aims to remove friction so you're more inclined to save reusable commands. In this case, we can shift querying and formatting into the template.
<<Width:200>>
can be interpreted as "ask the user for a value using the suggested prompt and default value."
With template queries in mind, dwim-shell-commands-make-transparent-png
can be further reduced to essentially the interactive command boilerplate and the template itself:
(defun dwim-shell-commands-make-transparent-png () "Create a transparent png." (interactive) (dwim-shell-command-on-marked-files "Create transparent png" "convert -verbose -size <<Width:200>>x<<Height:200>> xc:none '<<empty<<Width:200>>x<<Height:200>>.png(u)>>'" :utils "convert"))
Note: Any repeated queries (same prompt and default) are treated as equal. That is, ask the user once and replace everywhere. If you'd like to request separate values, change either prompt or the default value.
Seamless command-line utils
Just the other day, I received a restaurant menu split into a handful of image files. I wanted to forward the menu to others but figured I should probably send it as a single file.
ImageMagick's convert command-line utility works great for this purpose. Feed it some images and it creates a pdf for you:
convert image1.png image2.png image3.png combined.pdf
Using convert
for this purpose was pretty straightforward. I'm sure I'll use it again in a similar context, but what if I can make future usage more seamless? In the past, I would just make a note of usage and revisit when needed. Though this works well enough, it often requires some amount of manual work (looking things up, tweaking command, etc) if you happen to forget the command syntax.
I wanted common one-liners (or longer shell scripts) to be easily reusable and accessible from Emacs. Turns out, the dwim-shell-command experiment is working fairly well for this purpose. In addition to providing template expansion, it generally tries to do what I mean (focus when needed, reveal new files, rename buffers, etc).
Here's how I saved the convert
command instance for future usage:
(defun dwim-shell-commands-join-as-pdf () "Join all marked images as a single pdf." (interactive) (dwim-shell-command-on-marked-files "Join as pdf" "convert -verbose '<<*>>' '<<joined.pdf(u)>>'" :utils "convert"))
From now on, any time I'd like to join multiple files into a pdf, I can now select them all and invoke dwim-shell-commands-join-as-pdf
.
In the saved command, '<<*>>'
expands to either dired selected files or whatever file happens to be open in the current buffer. The buffer file isn't of much help for joining multiple items, but can be handy for other instances (say I want to convert current image to jpeg).
Moving on to '<<joined.pdf(u)>>'
, we could have just written as joined.pdf
, but wrapping it ensures the resulting file name is unique. That is, if joined.pdf
already exists, write joined(1).pdf
instead.
These kinds of command-line integrations are working well for me. Take the webp animation above, it was created by invoking dwim-shell-commands-video-to-webp
on a .mov
file. Easy peasy. While I can easily memorize the convert
command for the pdf instance, I'm hopeless in the webp scenario:
ffmpeg -i '<<f>>' -vcodec libwebp -filter:v fps=fps=10 -compression_level 3 -lossless 1 -loop 0 -preset default -an -vsync 0 '<<fne>>'.webp
While searching through command line history helps to quickly re-spin previous commands, it requires remembering the actual utility used for any particular action. On the other hand, wrapping with Emacs functions enables me to remember the action itself, using more memorable names. Also, fuzzy searching works a treat.
It's been roughly a month since I started playing around with this idea of wrapping command-line utilities more seamlessly. Since then, I've brought in a bunch of use-cases that are now quickly accessible (all in dwim-shell-commands.el):

Emacs freebie: macOS emoji picker
I recently ran a little experiment to bring macOS's long-press-accents-like behavior to Emacs. What I forgot to mention is that macOS's character viewer just works from our beloved editor.
If you have a newer MacBook model, you can press the 🌐 key to summon the emoji picker (character viewer). You may need to set this key binding from macOS keyboard preferences.
I'm happy to take this Emacs freebie, kthxbye.
Edits:
- Like other macOS apps, this dialog can be invoked via control-command-space (thanks mtndewforbreakfast). Note: you'd lose this ability if you
(setq mac-command-modifier 'meta)
in your config. - The 🌐 key is a feature on newer MacBook hardware and likely needs configuration (thanks Fabbi-).
dwim-shell-command video streams
I continue hunting for use-cases I can migrate to dwim-shell-command… After adding clipboard support (via ) I found one more.
- Copy URL from browser.
- Invoke
dwim-shell-commands-mpv-stream-clipboard-url
. - Enjoy picture in picture from Emacs ;)
What's the secret sauce? Very little. Invoke the awesome mpv with a wrapping function using dwim-shell-command-on-marked-files
.
(defun dwim-shell-commands-mpv-stream-clipboard-url () "Stream clipboard URL using mpv." (interactive) (dwim-shell-command-on-marked-files "Streaming" "mpv --geometry=30%x30%+100%+0% \"<<cb>>\"" :utils "mpv" :no-progress t :error-autofocus t :silent-success t))
The typical progress bar kinda got in the way, so I added a new option :no-progress
to dwim-shell-command-on-marked-files
, so it can be used for cases like this one.
An accentuated Emacs experiment (à la macOS)
macOS has a wonderful input mechanism where you press and hold a key on your keyboard to display the accent menu. It's easy to internalize: long press "a" if you want to input "á".
On Emacs, C-x 8 ' a would be the equivalent, but it just didn't stick for me. Fortunately, there's an alternative, using dead keys. Mickey Petersen gives a wonderful introduction. Having said all this, I still longed for macOS's input mechanism.
Thanks to Christian Tietze's post, I discovered the accent package. While it doesn't handle press-and-hold, it does the heavy lifting of offering a menu with character options. If I could just bring that press-and-hold…
My initial attempt was to use key chords (via use-package):
(use-package accent :ensure t :chords (("aa" . ar/spanish-accent-menu) ("ee" . ar/spanish-accent-menu) ("ii" . ar/spanish-accent-menu) ("oo" . ar/spanish-accent-menu) ("uu" . ar/spanish-accent-menu) ("AA" . ar/spanish-accent-menu) ("EE" . ar/spanish-accent-menu) ("II" . ar/spanish-accent-menu) ("OO" . ar/spanish-accent-menu) ("UU" . ar/spanish-accent-menu) ("nn" . ar/spanish-accent-menu) ("NN" . ar/spanish-accent-menu) ("??" . ar/spanish-accent-menu) ("!!" . ar/spanish-accent-menu)) :config (defun ar/spanish-accent-menu () (interactive) (let ((accent-diacritics '((a (á)) (e (é)) (i (í)) (o (ó)) (u (ú ü)) (A (Á)) (E (É)) (I (Í)) (O (Ó)) (U (Ú Ü)) (n (ñ)) (N (Ñ)) (\? (¿)) (! (¡))))) (ignore-error quit (accent-menu)))))
While it kinda works, "nn" quickly got in the way of my n/p magit navigation. Perhaps key chords are still an option for someone who doesn't need the "nn" chord, but being a Spanish speaker, I need that "ñ" from long "n" presses!
I'm now trying a little experiment using an after-change-functions
hook to monitor text input and present the accent menu. I'm sure there's a better way (anyone with ideas?). For now, it gives me something akin to press-and-hold.
I'm wrapping the hook with a minor mode to easily enable/disable whenever needed. I'm also overriding accent-diacritics
to only include the characters I typically need.
(use-package accent :ensure t :hook ((text-mode . accent-menu-mode) (org-mode . accent-menu-mode) (message-mode . accent-menu-mode)) :config (setq accent-diacritics '((a (á)) (e (é)) (i (í)) (o (ó)) (u (ú ü)) (A (Á)) (E (É)) (I (Í)) (O (Ó)) (U (Ú Ü)) (n (ñ)) (N (Ñ)) (\? (¿)) (! (¡)))) (defvar accent-menu-monitor--last-edit-time nil) (define-minor-mode accent-menu-mode "Toggle `accent-menu' if repeated keys are detected." :lighter " accent-menu mode" (if accent-menu-mode (progn (remove-hook 'after-change-functions #'accent-menu-monitor--text-change t) (add-hook 'after-change-functions #'accent-menu-monitor--text-change 0 t)) (remove-hook 'after-change-functions #'accent-menu-monitor--text-change t))) (defun accent-menu-monitor--text-change (beginning end length) "Monitors text change BEGINNING, END, and LENGTH." (let ((last-edit-time accent-menu-monitor--last-edit-time) (edit-time (float-time))) (when (and (> end beginning) (eq length 0) last-edit-time (not undo-in-progress) ;; 0.27 seems to work for my macOS keyboard settings. ;; Key Repeat: Fast | Delay Until Repeat: Short. (< (- edit-time last-edit-time) 0.27) (float-time (time-subtract (current-time) edit-time)) (accent-menu-monitor--buffer-char-string (1- beginning)) (seq-contains-p (mapcar (lambda (item) (symbol-name (car item))) accent-diacritics) (accent-menu-monitor--buffer-char-string beginning)) (string-equal (accent-menu-monitor--buffer-char-string (1- beginning)) (accent-menu-monitor--buffer-char-string beginning))) (delete-backward-char 1) (ignore-error quit (accent-menu))) (setq accent-menu-monitor--last-edit-time edit-time))) (defun accent-menu-monitor--buffer-char-string (at) (when (and (>= at (point-min)) (< at (point-max))) (buffer-substring-no-properties at (+ at 1)))))
As a bonus, it ocurred to me that I could use the same press-and-hold to handle question marks in Spanish (from my UK keyboard).
dwim-shell-command improvements
Added a few improvements to dwim-shell-command.
Dired region
In DWIM style, if you happen to have a dired region selected, use region files instead. There's no need to explicitly mark them.
Clipboard (kill-ring) replacement
Use <<cb>>
to substitute with clipboard content. This is handy for cloning git repos, using a URL copied from your browser.
git clone <<cb>>
This illustrates <<cb>>
usage, but you may want to use dwim-shell-commands-git-clone-clipboard-url
from dwim-shell-commands.el instead. It does the same thing internally, but makes the command more accessible.
(defun dwim-shell-commands-git-clone-clipboard-url () "Clone git URL in clipboard to `default-directory'." (interactive) (dwim-shell-command-on-marked-files (format "Clone %s" (file-name-base (current-kill 0))) "git clone <<cb>>" :utils "git"))
Counter replacement
Use <<n>>
to substitute with a counter. You can also use <<3n>>
to start the counter at 3.
Handy if you'd like to consistently rename or copy files.
mv '<<f>>' 'image(<<n>>).png'
Can also use an alphabetic counter with <<an>>
. Like the numeric version, can use any letter to start the counter with.
mv '<<f>>' 'image(<<an>>).png'
Prefix counter
Use a prefix command argument on dwim-shell-commands
to repeat the command a number of times. Combined with a counter, you can make multiple copies of a single file.
Optional error prompt
Set dwim-shell-command-prompt-on-error
to nil to skip error prompts. Focus process buffers automatically instead.
Configurable prompt
By default, dwim-shell-command
shows all supported placeholders. You can change that prompt to something shorter using dwim-shell-command-prompt
.
⚠️ Use with care ⚠️
The changes are pretty fresh. Please use with caution (specially the counter support).
dwim-shell-command on Melpa
Figure 7: <<cb>>
gets replaced by a clipboard (kill ring) URL
My pull request to add dwim-shell-command to melpa has been merged. Soon, you'll be able to install directly from Milkypostman’s Emacs Lisp Package Archive.
dwim-shell-command
is another way to invoke shell commands from our beloved editor. Why a different way? It does lots of little things for you, removing friction you didn't realise you had. You can check out the README, but you'll appreciate it much more once you try it out.
In addition, it's enabled me to bring lots of command-line tools into my Emacs config and make them highly accessible. You can see my usages over at dwim-shell-command-commands.el.
What kind of command-line tools? ffmpeg, convert, gifsycle, atool, qdpf, plutil, qrencode, du, sips, iconutil, and git (so far anyway). Below is a simple example, but would love to hear how you get to use it.
(defun dwim-shell-command-audio-to-mp3 () "Convert all marked audio to mp3(s)." (interactive) (dwim-shell-command-on-marked-files "Convert to mp3" "ffmpeg -stats -n -i '<<f>>' -acodec libmp3lame '<<fne>>.mp3'" :utils "ffmpeg"))
I've written about dwim-shell-command
before:
- Emacs: DWIM shell command (multi-language)
- png to icns (Emacs DWIM style)
- Emacs: Password-protect current pdf (revisited)
- Emacs DWIM shell-command
Irreal's also covered it:
A lifehack for your shell
I'm a fan of the unzip command line utility that ships with macOS. I give it a .zip file and it unzips it for me. No flags or arguments to remember (for my typical usages anyway). Most importantly, I've fully internalized the unzip
command into muscle memory, probably because of its perfect mnemonic.
But then there's .tar, .tar.gz, .tar.xz, .rar, and a whole world of compression archives, often requiring different tools, flags, etc. and I need to remember those too.
Can't remember where I got this "life hack" from, but it suggests something along the lines of…
Once you find a lost item at home, place it in the first spot you looked.
Great, I'll find things quickly. Win.
Now, I still remember a couple of unarchiving commands from memory (looking at you tar xvzf
), but I've noticed the first word that pops into mind when extracting is always unzip
.
There's the great atool wrapper out there to extract all kinds of archives (would love to hear of others), but unlucky for me, its name never comes to mind as quickly as unzip
does.
With "life hack" in mind, let's just create an unzip
eshell alias to atool
. Next time I need to unarchive anything, the first word that comes to mind (unzip!) will quickly get me on my way…
alias unzip 'atool --extract --explain $1'
Or if you prefer to add to your Emacs config:
(eshell/alias "unzip" "atool --extract --explain $1")
While I'm fan of Emacs eshell, it's not everyone's cup of tea. Lucky for us all, aliases are a popular feature across shells. Happy unzipping!
Bonus
Since I'm a keen on using "unzip" mnemonic everywhere in Emacs (not just my shell), I now have a DWIM shell-command for it:
(defun dwim-shell-command-unzip () "Unzip all marked archives (of any kind) using `atool'." (interactive) (dwim-shell-command-on-marked-files "Unzip" "atool --extract --explain '<<f>>'" :utils "atool"))
UPDATE:
Aliases missing on remote machines
Concerns about aliases not available on remote machines. Valid. Certainly brings challenges if you can't modify the environment on the remote machine. The severity would depend on how frequently you have to do this. Fortunately for me, it's infrequent.
Additionally, if accessing remote machine via eshell, this is a non-issue. You get to transparently bring most of your environment with you anyway.
Unzip keyword is overloaded
The alias is overloading the unzip command. I know. It's a little naughty. Going with it for now. I used to use "extract" (also in comments), which I still like but somehow "unzip" still wins my memory race. There's also "x" (nice option), which seems to originate from prezto. I could consider unzipp, unzip1, or some other variation.
Not sure how I missed this, but there's also an existing alias for atool: aunpack. Could be a great alternative.
Pause before extracting archives
Valid point. In my case, the pause typically happens before I invoke the alias.
Littering
If the archive didn't have a root dir, it can litter your current directory. Indeed a pain to clean up. For this, we can atool's --subdir
param to always create subdirectory when extracting.
Alias to retrain
Neat trick: alias unzip = “echo ‘use atool’”
to help retrain yourself. Reminds me of Emacs guru-mode.
Emacs zones to lift you up
As I prune my Emacs config off, I came across a forgotten bit of elisp I wrote about 6 years ago. While it's not going to power up your Emacs fu, it may lift your spirits, or maybe just aid discovery of new words.
You see, I had forgotten about zone.el altogether: a fabulous package to tickle your heart. You can think of it as screensaver built into Emacs.
If the built-in zones don't do it for ya, check out the few on melpa (nyan, sl, and rainbow).
So, my nostalgic bit of elisp dates Jun 17 2016
: a basic but functional zone (zone-words), displaying words from WordNet. Surely the package can use plenty of improvements (here's one), but hey this is Emacs and pretty much all existing code will run, no matter how old. In Emacs time, 2016 is practically yesterday!
Emacs: DWIM shell command (multi-language)
UPDATE: dwim-shell-command is now available on melpa.
I keep on goofying around with dwim-shell-command and it's sibling dwim-shell-command-on-marked-files
from dwim-shell-command.el.
In addition to defaulting to zsh, dwim-shell-command-on-marked-files
now support other shells and languages. This comes in handy if you have snippets in different languages and would like to easily invoke them from Emacs. Multi-language support enables "using the best tool for the job" kinda thing. Or maybe you just happen to know how to solve a particular problem in a specific language.
Let's assume you have an existing Python snippet to convert files from csv to json. With dwim-shell-command-on-marked-files
, you can invoke the Python snippet to operate on either dired or buffer files.
(defun dwim-shell-command-csv-to-json-via-python () "Convert csv file to json (via Python)." (interactive) (dwim-shell-command-on-marked-files "Convert csv file to json (via Python)." " import csv import json text = json.dumps({ \"values\": list(csv.reader(open('<<f>>')))}) fpath = '<<fne>>.json' with open(fpath , 'w') as f: f.write(text)" :shell-util "python" :shell-args "-c"))
Or, maybe you prefer Swift and already had a snippet for the same thing?
(defun dwim-shell-command-csv-to-json-via-swift () "Convert csv file to json (via Swift)." (interactive) (dwim-shell-command-on-marked-files "Convert csv file to json (via Swift)." " import Foundation import TabularData let filePath = \"<<f>>\" print(\"reading \\(filePath)\") let content = try String(contentsOfFile: filePath).trimmingCharacters(in: .whitespacesAndNewlines) let parsedCSV = content.components(separatedBy: CSVWritingOptions().newline).map{ $0.components(separatedBy: \",\") } let jsonEncoder = JSONEncoder() let jsonData = try jsonEncoder.encode([\"value\": parsedCSV]) let json = String(data: jsonData, encoding: String.Encoding.utf8) let outURL = URL(fileURLWithPath:\"<<fne>>.json\") try json!.write(to: outURL, atomically: true, encoding: String.Encoding.utf8) print(\"wrote \\(outURL)\")" :shell-pipe "swift -"))
You can surely solve the same problem in elisp, but hey it's nice to have options and flexibility.
png to icns (Emacs DWIM style)
UPDATE: dwim-shell-command is now available on melpa.
Since writing a DWIM version of the shell-command, I've been having a little fun revisiting command line utilities I sometimes invoke from my beloved editor. In this instance, converting a png file to an icns icon. What's more interesting about this case is that it's not just a one-liner, but a short script in itself. Either way, it's just as easy to invoke from Emacs using dwim-shell-command--on-marked-files

Emacs: Password-protect current pdf (revisited)
UPDATE: dwim-shell-command is now available on melpa.
With a recent look at writing DWIM shell commands, I've been revisiting my custom Emacs functions invoking command line utilities.
Take this post, for example, where I invoke qpdf via a elisp. Using the new dwim-shell-command--on-marked-files
in dwim-shell-command.el, the code is stripped down to a bare minimum:
(defun dwim-shell-commands-pdf-password-protect () "Password protect pdf." (interactive) (dwim-shell-command-on-marked-files "Password protect pdf" (format "qpdf --verbose --encrypt '%s' '%s' 256 -- '<<f>>' '<<fne>>_enc.<<e>>'" (read-passwd "user-password: ") (read-passwd "owner-password: ")) :utils "qpdf" :extensions "pdf"))
Compare the above dwim-shell-command--on-marked-files
usage to my previous implementation:
(defun pdf-password-protect () "Password protect current pdf in buffer or `dired' file." (interactive) (unless (executable-find "qpdf") (user-error "qpdf not installed")) (unless (equal "pdf" (or (when (buffer-file-name) (downcase (file-name-extension (buffer-file-name)))) (when (dired-get-filename nil t) (downcase (file-name-extension (dired-get-filename nil t)))))) (user-error "no pdf to act on")) (let* ((user-password (read-passwd "user-password: ")) (owner-password (read-passwd "owner-password: ")) (input (or (buffer-file-name) (dired-get-filename nil t))) (output (concat (file-name-sans-extension input) "_enc.pdf"))) (message (string-trim (shell-command-to-string (format "qpdf --verbose --encrypt '%s' '%s' 256 -- '%s' '%s'" user-password owner-password input output))))))
This really changes things for me. I'll be more inclined to add more of these tiny integrations to lots of great command line utilities. Take this recent Hacker News post on ocrmypdf as an example. Their cookbook has lots of examples that can be easily used via dwim-shell-command--on-marked-files
.
What command line utils would you use?
Emacs DWIM shell-command
UPDATE: dwim-shell-command is now available on melpa.
I've talked about DWIM before, where I bend Emacs to help me do what I mean. Emacs is also great for wrapping command-line one-liners with elisp, so I can quickly invoke commands without thinking too much about flags, arguments, etc.
I keep thinking the shell-command is ripe for plenty of enhancements using our DWIM fairydust.
Do what I mean how?
Smart template instantiation
I've drawn inspiration from dired-do-shell-command, which substitutes special characters like * and ? with marked files. I'm also drawing inspiration from org babel's noweb syntax to substitute <<f>>
(file path), <<fne>>
(file path without extension), and <<e>>
(extension). My initial preference was to use something like $f
, $fne
, and $e
, but felt they clashed with shell variables.
Operate on dired marked files
This is DWIM, so if we're visiting a dired buffer, the shell command should operate on all the marked files.
Operate on current buffer file
Similarly, if visiting a buffer with an associated file, operate on that file instead.
Automatically take me to created files
Did the command create a new file in the current directory? Take me to it, right away.
Show me output on error
I'm not usually interested in the command output when generating new files, unless there was an error of course. Offer to show it.
Show me output if no new files
Not all commands generate new files, so automatically show me the output for these instances.
Make it easy to create utilities
ffmpeg is awesome, but man I can never remember all the flags and arguments. I may as well wrap commands like these in a convenient elisp function and invoke via execute-extended-command, or my favorite counsel-M-x (with completion), bound to the vital M-x
.
All those gifs you see in this post were created with dwim-shell-command-convert-to-gif
, powered by the same elisp magic.
(defun dwim-shell-command-convert-to-gif () "Convert all marked videos to optimized gif(s)." (interactive) (dwim-shell-command--on-marked-files "Convert to gif" "ffmpeg -loglevel quiet -stats -y -i <<f>> -pix_fmt rgb24 -r 15 <<fne>>.gif" :utils "ffmpeg"))
This makes wrapping one-liners a breeze, so let's do some more…
(defun dwim-shell-command-convert-audio-to-mp3 () "Convert all marked audio to mp3(s)." (interactive) (dwim-shell-command-on-marked-files "Convert to mp3" "ffmpeg -stats -n -i '<<f>>' -acodec libmp3lame '<<fne>>.mp3'" :utils "ffmpeg")) (defun dwim-shell-command-convert-image-to-jpg () "Convert all marked images to jpg(s)." (interactive) (dwim-shell-command-on-marked-files "Convert to jpg" "convert -verbose '<<f>>' '<<fne>>.jpg'" :utils "convert")) (defun dwim-shell-command-drop-video-audio () "Drop audio from all marked videos." (interactive) (dwim-shell-command-on-marked-files "Drop audio" "ffmpeg -i '<<f>>' -c copy -an '<<fne>>_no_audio.<<e>>'" :utils "ffmpeg"))
Make it spin ;)
Ok, not quite, but use Emacs's progress-reporter just for kicks.
Use it everywhere
dwim-shell-command
covers my needs (so far anyway), so I'm binding it to existing bindings.
(use-package dwim-shell-command :bind ("M-!" . dwim-shell-command)) (use-package dired :bind (:map dired-mode-map ([remap dired-do-async-shell-command] . dwim-shell-command) ([remap dired-do-shell-command] . dwim-shell-command) ([remap dired-smart-shell-command] . dwim-shell-command)))
Bring those command line utilities
On the whole, this really changes things for me. I'll be more inclined to bring command line utilities to seamless Emacs usage. Take this recent Hacker News post on ocrmypdf as an example. Their cookbook has lots of examples that can be easily used via dwim-shell-command--on-marked-files
. What command line utilities would you bring?
Where's the code?
UPDATE: dwim-shell-command is now available on melpa.
The code for dwim-shell-command.el is likely a bit rough still, but you can take a peak if interested. Keep in mind this is DWIM, tailored for what ✨I✨ mean. Some of the current behavior may not be your cup of tea, but this is Emacs. You can bend it to do what ✨you✨ mean. Happy Emacsing.
Emacs: Password-protect current pdf
UPDATE: Check out Password-protect current pdf (revisted) for a simpler version.
Every so often, I need to password-protect a pdf. On macOS, Preview has a simple solution, but I figured there must be a command line utility to make this happen. There are options, but qdf did the job just fine.
qpdf --verbose --encrypt USER-PASSWORD OWNER-PASSWORD KEY-LENGTH -- input.pdf output.pdf
So what does qpdf
have to do with Emacs? Command-line utilities are easy to invoke from Emacs via shell-command
(M-!), but I don't want to remember the command nor the parameters. I may as well add a function that does what I mean and password-protect either buffers or dired files.
(defun pdf-password-protect () "Password protect current pdf in buffer or `dired' file." (interactive) (unless (executable-find "qpdf") (user-error "qpdf not installed")) (unless (equal "pdf" (or (when (buffer-file-name) (downcase (file-name-extension (buffer-file-name)))) (when (dired-get-filename nil t) (downcase (file-name-extension (dired-get-filename nil t)))))) (user-error "no pdf to act on")) (let* ((user-password (read-passwd "user-password: ")) (owner-password (read-passwd "owner-password: ")) (input (or (buffer-file-name) (dired-get-filename nil t))) (output (concat (file-name-sans-extension input) "_enc.pdf"))) (message (string-trim (shell-command-to-string (format "qpdf --verbose --encrypt '%s' '%s' 256 -- '%s' '%s'" user-password owner-password input output))))))
Plain Org v1.4 released
Plain Org v1.4 is now available on the App Store.
I was on a long flight recently 🦘, so I gave list and checkbox editing a little love. There's a couple of other minor improvements included.
If you haven't heard of Plain Org, it gives you access to org files on iPhone while away from your beloved Emacs.
I love org markup, but we (iPhone + org users) are a fairly niche bunch. If you're finding Plain Org useful, please help support this effort by getting the word out. Tell your friends, tweet, or blog about it.
On to v1.4 release notes…
Improved list/checkbox editing
Adding list or checkbox items is traditionally cumbersome via the iPhone's keyboard. This release adds new toolbar actions and smart return to simplify things.
Render form feed characters
Form feed characters are now rendered within expanded headings.
Note: There's a limitation. Form feed characters at the end of a heading aren't currently displayed.
Other
Increased all button tap areas in edit toolbar. This should hopefully improve interaction.
Plain Org v1.3 released
Plain Org v1.3 is now available on the App Store. The update receives a few features, bug fixes, and improvements.
If you haven't heard of Plain Org, it gives you access to org files on iPhone while away from your beloved Emacs.
I love org markup, but we (iPhone + org users) are a fairly niche bunch. If you're finding Plain Org useful, please help support this effort by getting the word out. Tell your friends, tweet, or blog about it.
On to v1.3 release notes…
Toggle recurring tasks
You can now toggle recurring tasks with either catchup <2022-04-15 Fri ++1d>
, restart <2022-04-15 Fri .+1d>
, or cumulate <2022-04-15 Fri +1d>
repeaters.
Log state transitions
Fullscreen view
The navigation bar now hides on scroll. This can be enabled/disabled via View > Full Screen
menu.
The previous screenshot text comes from Org Mode - Organize Your Life In Plain Text, a magnificent org resource.
Deadline and scheduled date rendered
In the past, SCHEDULED
and DEADLINE
were rendered (but only one of them at a time). Now both are rendered alongside each other (deadline has an orange tint).
Roundtripping fidelity
Many roundtripping fidelity improvements included in 1.3. Shoutout to u/Oerm who reported unnecessary formatting changes in unmodified areas and helped test all fixes.
Other bug fixes improvements
- Disable raw text edit menu when file is not accessible.
- Minor improvements to inline editing layouts (vertical height and drawers).
- ABRT and HABIT now recognized as a popular keywords.
- Improve state transition alignment to match org mode behaviour.
- Fixes roundtripping state transition notes (leading to data loss).
- Log creation from share sheet.
- Increment DEADLINE and SCHEDULED, not just first found.
- Roundtrip more whitespace in untouched areas.
- Fixes org syntax inadvertently parsed within begin_src blocks (leading to data loss).
Plain Org v1.2.1 released
Plain Org v1.2.1 is now available on the App Store. The update receives minor features, bug fixes, and improvements.
If you haven't heard of Plain Org, it gives you access to org files on iPhone while away from your beloved Emacs.
I love org markup, but we (iPhone + org users) are a fairly niche userbase. If you're finding Plain Org useful, please help support this effort by getting the word out. Tell your friends, tweet, or blog about it.
On to v1.2.1 release notes…
Render LOGBOOK
State transitions and LOGBOOK drawers are now recognized and rendered as such.
Either of the following snippets are rendered as togglable LOGBOOK drawers.
* TODO Feed the fish - State "DONE" from "TODO" [2022-03-11 Fri 12:23]
* TODO Feed the cat :LOGBOOK: - State "DONE" from "TODO" [2022-03-11 Fri 12:23] :END:
Add task to top/bottom
Up until now, tasks were always appended to the bottom of things. This didn't work so well if you like seeing recent items bubbling up to the top.
This version adds a new setting: Settings > Add new tasks to > Top/Bottom, giving you the choice.
Note: Top is the new default value, please change this setting if you'd like to keep the previous behaviour.
Checking for changes
Local file changes aren't always detected via state change notifications, so additional checks are now in place to offer reloading files.
Open inactive files
After adding new tasks via iOS's share sheet, if the item was added to a file other than the active one, offer to open that instead.
Other improvements
- Color keyword red/green depending on #+TODO: position.
- Round-trip planning order (SCHEDULED, CLOSED, DEADLINE).
- Improve tag alignment to match org mode behaviour (best effort, sorry).
- Improve vertical spacing prior to lists.
- Improve share sheet reliability.
- Fix opening local links from list items.
- Fix indent for list items without previous content.
- Fix race condition in adding TITLE and ID to new files.
- Fix incorrect keyword color selection in search toolbar.
- Fix menu inadvertently closing.
- Fix menu tapping for iPad.
Emacs DWIM: swiper vs isearch vs phi-search
I've talked about DWIM in the past, that wonderful Emacs ability to do what ✨I✨ mean.
Emacs being hyper-configurable, we can always teach it more things, so it can do exactly what we mean.
There are no shortages of buffer searching packages for Emacs. I'm a fan of Oleh Krehel's swiper, but before that, I often relied on the built-in isearch. Swiper is my default goto mechanism and have it bound to C-s
(replacing the built-in isearch-forward).
Swiper services most needs until I start combining with other tools. Take keyboard macros and multiple cursors. Both wonderful, but neither can rely on swiper to do their thing. Ok, swiper does, but in a different way.
Rather than binding C-s
to swiper, let's write a DWIM function that's aware of macros and multiple cursors. It must switch between swiper, isearch, and phi-search depending on what I want (search buffer, define macro, or search multiple cursors).
Let's also tweak swiper's behavior a little further and prepopulate its search term with the active region. Oh, and I also would like swiper to wrap around (see ivy-wrap). But only swiper, not other ivy utilities. I know, I'm picky, but that's the whole point of DWIM… so here's my function to search forward that does exactly what ✨I✨ mean:
(defun ar/swiper-isearch-dwim () (interactive) ;; Are we using multiple cursors? (cond ((and (boundp 'multiple-cursors-mode) multiple-cursors-mode (fboundp 'phi-search)) (call-interactively 'phi-search)) ;; Are we defining a macro? (defining-kbd-macro (call-interactively 'isearch-forward)) ;; Fall back to swiper. (t ;; Wrap around swiper results. (let ((ivy-wrap t)) ;; If region is active, prepopulate swiper's search term. (if (and transient-mark-mode mark-active (not (eq (mark) (point)))) (let ((region (buffer-substring-no-properties (mark) (point)))) (deactivate-mark) (swiper-isearch region)) (swiper-isearch))))))
The above snippet searches forward, but I'm feeling a little off-balance. Let's write an equivalent to search backwards. We can then bind it to C-r
, also overriding the built-in isearch-backward.
(defun ar/swiper-isearch-backward-dwim () (interactive) ;; Are we using multiple cursors? (cond ((and (boundp 'multiple-cursors-mode) multiple-cursors-mode (fboundp 'phi-search-backward)) (call-interactively 'phi-search-backward)) ;; Are we defining a macro? (defining-kbd-macro (call-interactively 'isearch-backward)) ;; Fall back to swiper. (t ;; Wrap around swiper results. (let ((ivy-wrap t)) ;; If region is active, prepopulate swiper's search term. (if (and transient-mark-mode mark-active (not (eq (mark) (point)))) (let ((region (buffer-substring-no-properties (mark) (point)))) (deactivate-mark) (swiper-isearch-backward region)) (swiper-isearch-backward))))))
These may be on the hacky side of things, but hey… they do the job. If there are better/supported ways of accomplishing a similar thing, I'd love to hear about it.
Grandma's vanilla pound cake
My grandmother Hilda used to bake this for us grandkids. I don't know the origin of the recipe, but my parents, aunts, and cousins, they all bake it too. I'm a big fan, but only get to eat it when visiting. Yesterday, I changed that. Finally baked it myself \o/
Ingredients
- 200g salted butter
- 2 cups (400 g) sugar
- 4 eggs
- 3 cups (375 g) plain flour
- 3 teaspoons baking powder
- 1 tablespoon (15 ml) vanilla extract
- 1 cup (250 ml) milk
- 2 tablespoons (30 ml) Málaga Virgen wine (port works too)
Prep
- Ensure all ingredients are at room temperature before you start.
- Preheat oven at 175C.
- Separate egg yolks and whites. Keep both.
- Consolidate liquids into a bowl (milk + wine + vanilla).
- Consolidate sifted powders into a bowl (flour + baking powder).
Meringue
- Beat egg whites into a snowy meringue. Set aside.
Mixer
- Beat butter in the mixer until creamy (important).
- Add sugar and mix thoroughly ensuring creamy consistency remains (important).
- Mix yolks in thoroughly one by one.
- Mix in the meringue.
- You're done with the mixer.
Hand mixing
- With a wooden spoon, alternate hand mixing the liquids and the powders. Start with liquids and end with powders.
Pour into mould
- Pour the mix into a non-stick baking mould.
Bake
- Bake in oven between 60 and 70 mins, but don’t be afraid to leave longer if needed. Mileage varies across ovens.
- Use a cake tester after 60 minutes to decide how much longer to bake for (if needed).
Emacs: viewing webp images
There's a recent reddit post asking how to view webp images in Emacs. I didn't know the answer, but it's something I had wanted for some time. This post was a nice reminder to go and check things out. Was happy to contribute an answer.
Turns out, it's very simple. Just set image-use-external-converter
and install relevant external tools.
(setq image-use-external-converter t)
I'm a use-package
user, so I prefer to set with:
(use-package image :custom ;; Enable converting external formats (ie. webp) to internal ones. (image-use-external-converter t))
So what are the external tools needed? C-h v
image-use-external-converter
gives us the info we need:
If non-nil, create-image will use external converters for exotic formats.
Emacs handles most of the common image formats (SVG, JPEG, PNG, GIF and some others) internally, but images that don't have native support in Emacs can still be displayed if an external conversion program (like ImageMagick "convert", GraphicsMagick "gm" or "ffmpeg") is installed.
This variable was added, or its default value changed, in Emacs 27.1.
I happen to be a macOS user, so I install ImageMagick with:
brew install imagemagick
Emacs: Fuzzy search Apple's online docs
When building software for the Apple ecosystem, Xcode is often the editor of choice. With Emacs being my personal preference, I rarely find other iOS devs with a similar mindset.
When I saw Mikael Konradsson's post describing his Emacs Swift development setup, I reached out to say hello. While exchanging tips and tricks, the topic of searching Apple's docs came up. It had been a while since I looked into this, so it was a great reminder to revisit the space.
Back in June 2020, I wrote a snippet to fuzzy search hackingwithswift.com, using Emacs's ivy completion framework. With a similar online API, we could also search Apple's docs. Turns out, there is and we can we can use it to search developer.apple.com from our beloved editor.
;;; counsel-apple-search.el -*- lexical-binding: t; -*- (defun ar/counsel-apple-search () "Ivy interface for dynamically querying apple.com docs."

Plain Org v1.2 released
Although Plain Org v1.2 has been in the App Store for a little while, the release write-up was overdue, sorry. The update receives some new features and bugfixes.
If you haven't heard of Plain Org, it gives ya access to your org files on iOS while away from your beloved Emacs.
If you're finding Plain Org useful, please help support this effort by getting the word out. Tell your friends, tweet, or blog about it.
Ok, now on to what's included in the v1.2 release…
Edit heading sections inline
v1.0 introduced outline editing (for headings only). In v1.2, we can also edit section content. Press the return
key multiple times to exit out section editing.
Filter by keyword/priority/tag
From the search dialog, you can now filter by keyboard, priority, and tag.
Render drawers and properties
Drawers are now rendered and can be expanded to view their content.
Open files via the Files app's "Share" sheet
From the Files app, you can now explicitly request launching files in Plain Org by using the "Share" menu.
Render LaTeX src blocks (experimental)
This one has its rough edges at the moment, so have to mark it experimental, but… you can can now render #+begin_src latex
blocks.
Insert title/id in new files
New files created via Plain Org automatically get #+TITLE:
and :ID:
inserted by default as follows:
#+TITLE: My favorite title :PROPERTIES: :ID: 7C845D38-8D80-41B5-BEB1-94F673807355 :END:
UPDATE: Sorry, this feature currently has a bug. You may not get these values inserted into your new document. Working on a fix.
Adding new tags quicker
Add tags quicker via the new + button.
Enable/disable sticky tags
Keywords, indent, and tags are maintained when adding new headings via outline editing. If you prefer disabling sticky tags, this can now be disabled.
Improved navigation bar
v1.2 makes the navigation bar feel more at home on your iPhone. It uses a large title which scrolls into the navigation bar.
Bugfixes
- Fix table rendering for iPad width.
- Fix image's horizontal padding.
- Fix adding new tags on new headings.
- Fix snapshotting bug resulting in Syncthing conflicts.
- Fix tapping menu after presenting other dialogs.
- Filter out parenthesis in file-local keywords like
TODO(t)
. - Commit pending inline changes if search is requested.
- Fix opening local links inside tables.
- Roundtrip whitespace in empty headings.
- Roundtrip trailing whitespace when raw-editing heading content.
- Tapping on body content should not toggle expansion.
Happy New Year and forming new habits
Hacker News has a summary of Atomic Habits (the book). In my case, I really enjoyed reading the entire book. I liked its narrative, mixing actionable and concrete advice with personal stories and experiments.
After reading Atomic Habits during the first lockdown, I was excited to try out its actionables, specially tracking to keep me honest.
I tried a bunch of iOS apps, but wanted no friction, no tracking, no cloud, no social, no analytics, no account, etc. so eventually built Flat Habits (flathabits.com). Also wanted to own my habit data (as plain text), so I made sure Flat Habits stored its data locally as an org file.
I'm an Emacs nutter and can say the strength in habit tracking lies in removing daily friction from the tracking process itself. A quickly accessible mobile app can really help with that. For me, Emacs plays a less important role here. The plain text part is cherry on top (bringing piece of mind around lock-in). In my case, it's been months since I looked at the plain text file itself from an Emacs org buffer. The iOS app, on the other hand, gets daily usage.
As for forming lasting habits (the actual goal here)… it's been well over a year since I started running as a regular form of exercise. While reading Atomic Habits really changed how I think of habits, a tracker played a crucial part in the daily grind. I happen to have built a tracker that plays nice with Emacs.
It's a new year. If you're looking at forming new habits, you may want some inspiration and also practical and concrete guidance. The book Atomic Habits can help with that. You can decide on which apps and how to implement the tracking process later on. Pen and paper is also a viable option and there are plenty of templates you can download.
There's a surplus of habit-tracking apps on the app stores. I built yet another one for iOS, modeled after my needs.
Plain Org v1.1 released 🎄☃️
Plain Org v1.1 is now available on the App Store. The update receives new features and bugfixes.
If you're finding Plain Org useful, please help support this effort by getting the word out. Tell your friends, tweet, or blog about it.
What is Plain Org?
Ok, now on to what's included in the v1.1 release…
Compact mode
By default, Plain Org layout uses generous padding. The new option Menu -> View -> Compact mode
packs more content into your screen.
Regroup active and inactive tasks
Regrouping tasks now bubbles active ones up. Similarly, inactive tasks drop to the bottom of their node. Changes are persisted to the org file.
Native table rendering
Tables are now rendered natively but also support displaying links and other formatting within cells.
Open local ID links
If your file provider supports granting access to folders, local ID links (ie. id:eb155a82-92b2-4f25-a3c6-0304591af2f9
) can now be resolved and opened from Plain Org. Note that for ID links to resolve, other org files must live in either the same directory or a subdirectory.
Fill paragraphs
If your org paragraphs contain newlines optimizing for bigger screens, you can toggle Menu -> View -> Fill paragraph
to optimize rendering for your iPhone. This rendering option makes no file modifications.
By the way, the previous screenshot text comes from Org Mode - Organize Your Life In Plain Text, a magnificent org resource.
Show/hide basic scheduling
Use the new Menu -> View -> Scheduling
to toggle showing SCHEDULED
or DEADLINE
dates.
Show/hide tags
Similarly, the new Menu -> View -> Tags
option toggles displaying tags.
Native list rendering
Lists are now rendered natively. With the exception of numbered cases, list items now share a common bullet icon. Description lists are also recognized and receive additional formatting when rendered.
- First list item * Second list item + Third list item 1. Numbered list item + Term :: Description for term
Numbered checkboxes are now recognized and receive the same formatting and interaction as their non-numbered counterparts.
1. [ ] First checkbox 2. [X] Second checkbox 3. [X] Third checkbox
Reload current file
Plain Org may not be able to automatically reload files for some syncing providers. In those instances, use Menu -> Reload
to explicitly request a reload.
Open .txt files
Although .org files are plain text files, they aren't always recognized by other text-editing apps. This release enables opening .txt files, so you can choose to render them in Plain Org, while giving you the option to edit elsewhere.
Bugfixes
- Improve vertical whitespace handling.
- Fixes rendering edge cases.
- Fail gracefully when creating new files on unsupported cloud providers.
- Prevent creating new files with redundant extensions.
- File access improvements.
- Replicates property spacing behaviour using Emacs's
org-property-format
default value. - Fixes keyword picker border rendering.
- Improves rendering performance for large nodes.
Emacs bends again
While adding more rendering capabilities to Plain Org, it soon became apparent some sort of screenshot/snapshot testing was necessary to prevent regressing existing features. That is, we first generate a rendered snapshot from a given org snippet, followed by some visual inspection, right before we go and save the blessed snapshot (often referred to as golden) to our project. Future changes are validated against the golden snapshot to ensure rendering is still behaving as expected.
Let's say we'd like to validate table rendering with links, we can write a test as follows:
func testTableWithLinks() throws { assertSnapshot( matching: OrgMarkupText.make( """ | URL | Org link | |------------------------+-------------| | https://flathabits.com | [[https://flathabits.com][Flat Habits]] | | Regular text | Here too | |------------------------+-------------| """), as: .image(layout: .sizeThatFits)) }
The corresponding snapshot golden can be seen below.
This is all done rather effortlessly thanks to Point Free's wonderful swift-snapshot-testing utilities.
So what does any of this have to do with Emacs? You see, as I added more snapshot tests and made modifications to the rendering logic, I needed a quick way to visually inspect and override all goldens. All the main pieces were already there, I just needed some elisp glue to bend Emacs my way™.
First, I needed to run my Xcode builds from the command line. This is already supported via xcodebuild. Next, I needed a way to parse test execution data to extract failing tests. David House's xcodebuild-to-json handles this perfectly. What's left? Glue it all up with some elisp.
Beware, the following code snippet is packed with assumptions about my project, it's messy, surely has bugs, can be optimized, etc. But the important point here is that Emacs is such an amazing malleable power tool. Throw some elisp at it and you can to bend it to your liking. After all, it's your editor.
And so here we are, I can now run snapshot tests from Emacs using my hacked up plainorg-snapshot-test-all
function and quickly override (or ignore) all newly generated snapshots by merely pressing y/n keys. Oh, and our beloved web browser was also invited to the party. Press "d" to open two browser tabs if you'd like to take a closer look (not demoed below).
Success. Emacs bends again.

Plain Org has joined the chat (iOS)
The App Store is a crowded space when it come to markdown apps. A quick search yields a wonderful wealth of choice. Kinda overwhelming, but a great problem to have nonetheless.
For those of us with org as our markup of choice, the App Store is far less crowded. I wish we could fill more than a screen's worth of search results, so you know… I could show you another pretty gif scrolling through org results. For now, we'll settle on a single frame showcasing our 4 org options.
Beorg, MobileOrg, Flat Habits, and Orgro are all great options. Each with strengths of their own. Organice, while not on the App Store, is another option for those looking for a web alternative. Of these, I had already authored one of them. More on that in a sec… You see, about a year ago I wanted to play with Swift, SPM, and lsp itself. Also, having Swift code completion in Emacs via lsp-sourcekit sounded like a fun thing to try out, so I started using it while writing a Swift org parser.
While working on the parser, I happened to be reading Atomic Habits (awesome book btw)… It was also a great time to play around with SwiftUI, which by the way, is pretty awesome too. With Atomic Habits fresh in mind, org parser in one hand, and SwiftUI in the other, I built Flat Habits: a lightweight habit tracker powered by org.
I love being able to save habit data to plain text and easily track on my iPhone (via Flat Habits) or laptop (via Emacs). I wanted to extend similar convenience to org tasks, so I built Plain Org.
My previous post mentioned quickly adding new tasks and searching existing ones as Plain Org's driving goals. Of course, neither of those are as useful without automatic cloud syncing, so pluging into iOS's third party cloud support was a must-have.
With these baseline features in place, I started an alpha/beta group via TestFlight. Early Plain Org adopters have been wonderfully supportive, given lots of great feedback, and helped shape the initial feature set you see below.
There's plenty more that can be supported, but hey let's get v1 out the door. Gotta start somewhere.
Plain Org v1 features
- View and edit your org mode tasks while on the go.
- Beautifully rendered org markup.
- Sync your org files using your favorite cloud provider.
- Create new files.
- Outline-style editing with toolbar

Plain Org joins the chat
Today Plain Org joins the likes of Beorg, MobileOrg, Flat Habits, and Orgro on the App Store.
Plain Org for iOS (a month later)
A month ago, I posted about my desire to bring org tasks/TODOs to iOS and make them quickly available from my iPhone.
Since then, I've received some great feedback, which I've been slowly chipping away at. My intent isn't so much to move my org workflow over to iOS, but to supplement Emacs while away from my laptop.
As of now, this is what the inline edit experience looks like:
If, like me, you prefer dark mode. The app's got ya covered:
Plain Org is not yet available on the App Store, but you can get a TestFlight invite if you send me an email address. Ping me on reddit, twitter, or email me at "plainorg" + "@" + "xenodium.com".
You can also check out progress over at the r/plainorg subreddit.
Org habits on iOS? Check! Tasks, you're next
I'm an org mode fan. This blog is powered by org. It's more of an accidental blog that started as a single org file keeping notes. I use org babel too. Oh and org habits. My never-ending list of TODOs is also powered by org. I manage all of this from Emacs and peek at TODOs using org agenda. This all works really well while I'm sitting in front of my laptop running Emacs.
But then I'm away from my laptop… and I need to quickly record habits on the go. I need it to be low-friction. Ssh'ing to an Emacs instance from a smartphone isn't an option. I'm an iPhone user, so whatever the solution, it should play nice with Emacs and org mode. I built Flat Habits for habit tracking and I'm fairly happy with the result. As of today, my longest-tracked habit is on a 452-day streak.
Moving on to org tasks/TODOs… I want something fairly frictionless while on the go. With Flat Habits as a stepping stone, I can now reuse some parts to build Plain Org. This new app should give me quick access to my tasks. The two driving goals are: quickly add new tasks and search existing ones while away from my laptop. Ok, maybe basic editing helps too. Oh and it should sync over cloud, of course.
I now have an early implementation of sorts, available on TestFlight. If you'd like to give it a try, send me an email address to receive the the invite. Ping me on reddit, twitter, or email me at "plainorg" + "@" + "xenodium.com".
Flat Habits 1.1 released
Flat Habits 1.1 is now available on the App Store. Flat Habits is a habit tracker that’s mindful of your time, data, and privacy. It's powered by org plain text markup, enabling you to use your favorite editor (Emacs, Vim, VSCode, etc.) to poke at your habit data.
What's new?
This release implements a few of features requested by users.
Multiday weekly habits
This is the chunkiest addition and most requested feature. You can now select multiple days when scheduling weekly habits.
Historical management
Sometimes you forget to mark a habit done or make a mistake toggling one. Either way, you can now toggle any habit day from the calendar/streak view.
Long tap
Long tap shows you the editing option available for that day.
Short tap
Short tap typically toggles between "Done" and "Not done".
Where's today?
A few folks rightfully asked for today's date to be highlighted in the calendar view, and so we now have a red circle.
Improved error messages
Hopefully you don't run into issues, but if you do, I hope the app helps ya sort them out.
Bugfixes
- Tapping on blur now dismisses habit edit dialog.
- Future habits now longer editable.
- Skipped habits no longer have a default tap action.
- Undoing from streak/calendar view now refreshes correctly.
- Undoing habit addition on iPad removes streak/calendar view.
macOS: Show in Finder / Show in Emacs
From Christian Tietze's Open macOS Finder Window in Emacs Dired, I learned about reveal-in-osx-finder. This is handy for the few times I want to transition from Emacs to Finder for file management. I say few times since Emacs's directory editor, dired, is just awesome. I've written about dired customizations here and here, but since dired is just another buffer, you can apply your Emacs magic like multiple cursors to batch rename files in an editable dired buffer.
To transition from macOS Finder to Emacs, Christian offers an Emacs interactive command that fetches Finder's location and opens a dired buffer via AppleScript. On a similar note, I learned from redditor u/pndc that Finder's proxy icons can be dragged over to Emacs, which handily drops ya into a dired buffer.
With these two solutions in mind, I looked into a third one to offer a context menu option in Finder to show the file in Emacs. This turned out to be fairly easy using Automator, which I've rarely used.
I created a flow that runs a shell script to "Show in Emacs", revealing the selected file or folder in an dired buffer. This is similar to Christian's solution, but invoked from Finder itself. The flow also uses dired-goto-file which moves the point (cursor) to the file listed under dired.
current_dir=$(dirname "$1") osascript -e 'tell application "Emacs" to activate' path/to/emacsclient --eval "(progn (dired \"$current_dir\") (dired-goto-file \"$1\"))"
As a bonus, I added an "Open in Emacs" option, which does as it says on the tin. Rather than show the file listed in a dired buffer, it gets Emacs to open it in your favorite major mode. This option is not technically needed since Finder already provides an "Open With" context menu, but it does remove a few click here and there.
osascript -e 'tell application "Emacs" to activate' /Users/alvaro/homebrew/bin/emacsclient --eval "(find-file \"$1\")"
On a side note, Emacs defaults to creating new frames when opening files via "Open With" menu (or "open -a Emacs foo.txt"). I prefer to use my existing Emacs frame, which can be accomplished by setting ns-pop-up-frames to nil.
(setq ns-pop-up-frames nil)
Emacs: smarter search and replace
Not long ago, I made a note to go back and read Mac for Translators's Emacs regex with Emacs lisp post. The author highlights Emacs's ability to apply additional logic when replacing text during a search-and-replace session. It does so by leveraging elisp expressions.
Coincidentally, a redditor recently asked What is the simplest way to apply a math formula to all numbers in a buffer/region? Some of the answers also point to search and replace leveraging elisp expressions.
While I rarely need to apply additional logic when replacing matches, it's nice to know we have options available in our Emacs toolbox. This prompted me to check out replace-regexp's documentation (via M-x describe-function or my favorite M-x helpful-callable). There's lots in there. Go check its docs out. You may be pleasantly surprised by all the features packed under this humble function.
For instance, \& expands to the current match. Similarly, \#& expands to the current match, fed through string-to-number. But what if you'd like to feed the match to another function? You can use \, to signal evaluation of an elisp expression. In other words, you could multiply by 3 using \,(* 3 \#&) or inserting whether a number is odd or even with something like \,(if (oddp \#&) "(odd)" "(even)").
Take the following text:
1 2 3 4 5 6
We can label each value "(odd)" or "(even)" as well as multiply by 3, by invoking replace-regexp as follows:
M-x replace-regexp
[PCRE] Replace regex:
[-0-9.]+
Replace regex [-0-9.]+:
\& \,(if (oddp \#&) "(odd)" "(even)") x 3 = \,(* 3 \#&)
1 (odd) x 3 = 3 2 (even) x 3 = 6 3 (odd) x 3 = 9 4 (even) x 3 = 12 5 (odd) x 3 = 15 6 (even) x 3 = 18
It's worth noting that replace-regexp's cousin query-replace-regexp also handles all this wonderful magic.
Happy searching and replacing!
Previewing SwiftUI layouts in Emacs (revisited)
Back in May 2020, I shared a snippet to extend ob-swift to preview SwiftUI layouts using Emacs org blocks.
When I say extend, I didn't quite modify ob-swift itself, but rather advised org-babel-execute:swift to modify its behavior at runtime.
Fast-forward to June 2021 and Scott Nicholes reminded me there's still interest in org babel SwiftUI support. ob-swift seems a little inactive, but no worries there. The package offers great general-purpose Swift support. On the other hand, SwiftUI previews can likely live as a single-purpose package all on its own… and so I set off to bundle the rendering functionality into a new ob-swiftui package.
Luckily, org babel's documentation has a straightforward section to help you develop support for new babel languages. They simplified things by offering template.el, which serves as the foundation for your language implementation. For the most part, it's a matter of searching, replacing strings, and removing the bits you don't need.
The elisp core of ob-swiftui is fairly simple. It expands the org block body, inserts the expanded body into a temporary buffer, and finally feeds the code to the Swift toolchain for execution.
(defun org-babel-execute:swiftui (body params) "Execute a block of SwiftUI code in BODY with org-babel header PARAMS. This function is called by `org-babel-execute-src-block'" (message "executing SwiftUI source code block") (with-temp-buffer (insert (ob-swiftui--expand-body body params)) (shell-command-on-region (point-min) (point-max) "swift -" nil 't) (buffer-string)))
The expansion in ob-swiftui–expand-body is a little more interesting. It decorates the block's body, so it can become a fully functional and stand-alone SwiftUI macOS app. If you're familiar with Swift and SwiftUI, the code should be fairly self-explanatory.
From an org babel's perspective, the expanded code is executed whenever we press C-c C-c (or M-x org-ctrl-c-ctrl-c) within the block itself.
It's worthing mentioning that our new implementation supports two babel header arguments (results and view). Both extracted from params using map-elt and replaced in the expanded Swift code to enable/disable snapshotting or explicitly setting a SwiftUI root view.
(defun ob-swiftui--expand-body (body params) "Expand BODY according to PARAMS and PROCESSED-PARAMS, return the expanded body." (let ((write-to-file (member "file" (map-elt params :result-params))) (root-view (when (and (map-elt params :view) (not (string-equal (map-elt params :view) "none"))) (map-elt params :view)))) (format " // Swift snippet heavily based on Chris Eidhof's code at: // https://gist.github.com/chriseidhof/26768f0b63fa3cdf8b46821e099df5ff import Cocoa import SwiftUI import Foundation let screenshotURL = URL(fileURLWithPath: NSTemporaryDirectory(), isDirectory: true).appendingPathComponent(ProcessInfo.processInfo.globallyUniqueString + \".png\") let preview = %s // Body to run. %s extension NSApplication { public func run<V: View>(_ view: V) { let appDelegate = AppDelegate(view) NSApp.setActivationPolicy(.regular) mainMenu = customMenu delegate = appDelegate run() } public func run<V: View>(@ViewBuilder view: () -> V) { let appDelegate = AppDelegate(view()) NSApp.setActivationPolicy(.regular) mainMenu = customMenu delegate = appDelegate run() } } extension NSApplication { var customMenu: NSMenu { let appMenu = NSMenuItem() appMenu.submenu = NSMenu() let quitItem = NSMenuItem( title: \"Quit \(ProcessInfo.processInfo.processName)\", action: #selector(NSApplication.terminate(_:)), keyEquivalent: \"q\") quitItem.keyEquivalentModifierMask = [] appMenu.submenu?.addItem(quitItem) let mainMenu = NSMenu(title: \"Main Menu\") mainMenu.addItem(appMenu) return mainMenu } } class AppDelegate<V: View>: NSObject, NSApplicationDelegate, NSWindowDelegate { var window = NSWindow( contentRect: NSRect(x: 0, y: 0, width: 414 * 0.2, height: 896 * 0.2), styleMask: [.titled, .closable, .miniaturizable, .resizable, .fullSizeContentView], backing: .buffered, defer: false) var contentView: V init(_ contentView: V) { self.contentView = contentView } func applicationDidFinishLaunching(_ notification: Notification) { window.delegate = self window.center() window.contentView = NSHostingView(rootView: contentView) window.makeKeyAndOrderFront(nil) if preview { screenshot(view: window.contentView!, saveTo: screenshotURL) // Write path (without newline) so org babel can parse it. print(screenshotURL.path, terminator: \"\") NSApplication.shared.terminate(self) return } window.title = \"press q to exit\" window.setFrameAutosaveName(\"Main Window\") NSApp.activate(ignoringOtherApps: true) } } func screenshot(view: NSView, saveTo fileURL: URL) { let rep = view.bitmapImageRepForCachingDisplay(in: view.bounds)! view.cacheDisplay(in: view.bounds, to: rep) let pngData = rep.representation(using: .png, properties: [:]) try! pngData?.write(to: fileURL) } // Additional view definitions. %s " (if write-to-file "true" "false") (if root-view (format "NSApplication.shared.run(%s())" root-view) (format "NSApplication.shared.run {%s}" body)) (if root-view body ""))))
For rendering inline SwiftUI previews in Emacs, we rely on NSView's bitmapImageRepForCachingDisplay to capture an image snapshot. We write its output to a temporary file and piggyback-ride off org babel's :results file header argument to automatically render the image inline.
Here's ob-swiftui inline rendering in action:
When rendering SwiftUI externally, we're effectively running and interacting with the generated macOS app itself.
The two snippets give a general sense of what's needed to enable org babel to handle SwiftUI source blocks. Having said that, the full source and setup instructions are both available on github.
ob-swiftui is now available on melpa.
Blurring the lines between shell and editor
I recently tweeted that Vivek Haldar's 10-year old post rings true today just the same. He writes about the levels of Emacs proficiency. All 6 levels are insightful in their own right, but for the sake of this post, let's quote an extract from level 4. Shell inside Emacs:
"And then, you learned about it: M-x shell.
It was all just text. Why did you need another application for it? Why should only the shell prompt be editable? Why can’t I move my cursor up a few lines to where the last command spewed out its results? All these problems simply disappear when your shell (or shells) simply becomes another Emacs buffer, upon which all of the text manipulation power of Emacs can be brought to bear."
In other words, we aren't merely removing shell restrictions, but opening up possibilities…
Take Emacs eshell looping, for example. I use it so infrequently, I could never remember eshell's syntax. I would refer back to EmacsWiki's Eshell For Loop or Mastering Emacs's Mastering Eshell comments for a reminder. It finally dawned on me. I don't need to internalize this eshell syntax. I have YASnippet available like any other buffer. I could just type "for" and let YASnippet do the rest for me.
All I need is a tiny YASnippet:
#name : Eshell for loop #key : for # -- for f in ${1:*} { ${2:echo} "$f"; $3} $0
Want a gentle and succinct YASnippet intro? Check out Jake's YASnippet introduction video.
If you're a shell-mode user, YASnippet would have you covered in your favorite shell. The expansion snippet can be modified to a Bash equivalent, giving us the same benefit. We type "for" and let YASnippet expand and hop over arguments. Here's a Bash equivalent emphasizing the hopping a little more:
#name : bash for loop #key : for # -- for f in ${1:*}; do ${2:echo} $f; done $0
ps. Looks like vterm, term, or ansi-term work too. See Shane Mulligan's post: Use YASnippets in term and vterm in emacs.
xcodebuild's SPM support (Xcode 11)
Had been a while since I looked into generating Xcode projects from a Swift package. On my latest use of the generate-xcodeproj subcommand, I was greeted by a nice warning surprise…
swift package generate-xcodeproj
warning: Xcode can open and build Swift Packages directly. 'generate-xcodeproj' is no longer needed and will be deprecated soon. generated: ./FooBar.xcodeproj
Xcode can handle Swift packages directly. Similarly, xcodebuild can handle them too. This isn't new. It's likely been available since Xcode 11. I just totally missed it.
Note: I've yet to dig into Xcode 13 beta, as Swift packages may already support the build/test features I was after in xcodebuild (like build/test on Catalyst).
In any case, on to xcodebuild… but let's first create a brand new Swift package.
Creating a Swift package library
mkdir FooBar && cd FooBar swift package init --type library
Creating library package: FooBar Creating Package.swift Creating README.md Creating .gitignore Creating Sources/ Creating Sources/FooBar/FooBar.swift Creating Tests/ Creating Tests/FooBarTests/ Creating Tests/FooBarTests/FooBarTests.swift
List package schemes
We can use xcodebuild to list the available schemes.
xcodebuild -list

Similarly, we can list destinations supported for the schemes.
xcodebuild -showdestinations -scheme FooBar

macOS builds
Let's build for macOS, though let's first import UIKit into FooBar.swift. This ensures we get an expected failure when building for macOS.
import UIKit struct FooBar { var text = "Hello, World!" }
Now let's attempt to build it…
xcodebuild build -quiet -scheme FooBar -destination 'platform=macOS'
--- xcodebuild: WARNING: Using the first of multiple matching destinations: { platform:macOS, arch:x86_64, id:3D097357-EB7D-565D-9058-CE7C3135927B } { platform:macOS, arch:x86_64, variant:Mac Catalyst, id:3D097357-EB7D-565D-9058-CE7C3135927B } /tmp/FooBar/Sources/FooBar/FooBar.swift:1:8: error: no such module 'UIKit' import UIKit ^ note: Using new build system note: Building targets in parallel note: Planning build note: Analyzing workspace note: Using build description from disk note: Build preparation complete ** BUILD FAILED **
The failure expected as UIKit isn't available on your typical macOS builds.
macOS Catalyst builds
We do, however, have Catalyst available, so we can use its variant to build for macOS with UIKit support, and.. voilà!
xcodebuild build -quiet -scheme FooBar -destination 'platform=macOS,variant=Mac Catalyst' && echo \\o/

Emacs org block completion on melpa
When enabled, the character "<" triggers company completion of org blocks.
I get the occasional ping to package the code from this post and publish it on melpa. Finally gave it a go. Moved the code here.
This was my first time publishing on melpa. The process was very smooth. Big thanks to melpa volunteers!
Emacs DWIM: do what ✨I✨ mean
Update: There's a DWIM follow-up for searching.
I was a rather puzzled the first time I spotted DWIM in an Emacs interactive command name. Don't think I remember what the command itself was, but what's important here is that DWIM stands for do what I mean.
I love DWIM interactive commands. They enable commands to be smarter and thus pack more functionality, without incurring the typical cognitive overhead associated with remembering multiple commands (or key bindings). The Emacs manual does a great job describing DWIM for the comment-dwim command:
The word “dwim” is an acronym for “Do What I Mean”; it indicates that this command can be used for many different jobs relating to comments, depending on the situation where you use it.
It's really great to find built-in DWIM-powered Emacs commands. Third-party packages often include them too. I typically gravitate towards these commands and bind them in my Emacs config. Examples being upcase-dwim, downcase-dwim, or mc/mark-all-dwim.
But what if the DWIM command doesn't exist or the author has written a command for what they mean? This is your editor, so you can make it do what you mean.
Take for example, org-insert-link, bound to C-c C-l by default. It's handy for inserting org mode links. I used it so frequently that I quickly internalized its key binding. Having said that, I often found myself doing some lightweight preprocessing prior to invoking org-insert-link. What if I can make org-insert-link do what I mean?
What do I mean?
Use URLs when in clipboard
If the URL is already in the clipboard, don't ask me for it. Just use it.
Use the region too
If I have a region selected and there's a URL in the clipboard, just sort it out without user interaction.
Automatically fetch titles
Automatically fetch URL titles from their HTML tag, but ask me for tweaks before insertion.
Fallback to org-insert-link
If my DWIM rules don't apply, fall back to using good ol' org-insert-link.
My most common use case here is when editing an existing link where I don't want neither its title nor URL automatically handled.
The code
This is your own DWIM command that does what you mean. Strive to write a clean implementation, but hey you can be forgiven for not handling all the cases that other folks may want or inlining more code than usual. The goal is to bend your editor a little, not write an Emacs package.
(defun ar/org-insert-link-dwim () "Like `org-insert-link' but with personal dwim preferences." (interactive) (let* ((point-in-link (org-in-regexp org-link-any-re 1)) (clipboard-url (when (string-match-p "^http" (current-kill 0)) (current-kill 0))) (region-content (when (region-active-p) (buffer-substring-no-properties (region-beginning) (region-end))))) (cond ((and region-content clipboard-url (not point-in-link)) (delete-region (region-beginning) (region-end)) (insert (org-make-link-string clipboard-url region-content))) ((and clipboard-url (not point-in-link)) (insert (org-make-link-string clipboard-url (read-string "title: " (with-current-buffer (url-retrieve-synchronously clipboard-url) (dom-text (car (dom-by-tag (libxml-parse-html-region (point-min) (point-max)) 'title)))))))) (t (call-interactively 'org-insert-link)))))
Org web tools package
I showed how to write your own DWIM command, so you can make Emacs do what ✨you✨ mean. ar/org-insert-link-dwim was built for my particular needs.
Having said all of this, alphapapa has built a great package with helpers for the org web/link space. It doesn't do what I mean (for now anyway), but it may work for you: org-web-tools: View, capture, and archive Web pages in Org-mode1.
Emacs link scraping (2021 edition)
A recent Hacker News post, Ask HN: Favorite Blogs by Individuals, led me to dust off my oldie but trusty command to extract comment links. I use it to dissect these wonderful references more effectively.
You see, I wrote this command back in 2015. We can likely revisit and improve. The enlive package continues to do a fine job fetching, parsing, and querying HTML. Let's improve my code instead… we can shed a few redundant bits and maybe use newer libraries and features.
Most importantly, let's improve the user experience by sanitizing and filtering URLs a little better.
We start by writing a function that looks for a URL in the clipboard and subsequently fetches, parses, and extracts all links found in the target page.
(require 'enlive) (require 'seq) (defun ar/scrape-links-from-clipboard-url () "Scrape links from clipboard URL and return as a list. Fails if no URL in clipboard." (unless (string-prefix-p "http" (current-kill 0)) (user-error "no URL in clipboard")) (thread-last (enlive-query-all (enlive-fetch (current-kill 0)) [a]) (mapcar (lambda (element) (string-remove-suffix "/" (enlive-attr element 'href)))) (seq-filter (lambda (link) (string-prefix-p "http" link))) (seq-uniq) (seq-sort (lambda (l1 l2) (string-lessp (replace-regexp-in-string "^http\\(s\\)*://" "" l1) (replace-regexp-in-string "^http\\(s\\)*://" "" l2))))))
Let's chat (current-kill 0) for a sec. No improvement from my previous usage, but let's just say building interactive commands that work with your current clipboard (or kill ring in Emacs terminology) is super handy (see clone git repo from clipboard).
Moving on to sanitizing and filtering URLs… Links often have trailing slashes. Let's flush them. string-remove-suffix to the rescue. This and other handy string-manipulating functions are built into Emacs since 24.4 as part of subr-x.el.
Next, we can keep http(s) links and ditch everything else. The end-goal is to extract links posted by users, so these are typically fully qualified external URLs. seq-filter steps up to the task, included in Emacs since 25.1 as part of the seq.el family. We remove duplicate links using seq-uniq and sort them via seq-sort. All part of the same package.
When sorting, we could straight up use seq-sort and string-lessp and nothing else, but it would separate http and https links. Let's not do that, so we drop http(s) prior to comparing strings in seq-sort's predicate. replace-regexp-in-string does the job here, but if you'd like to skip regular expressions, string-remove-prefix works just as well.
Yay, sorting no longer cares about http vs https:
https://andymatuschak.org http://antirez.com https://apenwarr.ca/log ...
With all that in mind, let's flatten list processing using thread-last. This isn't strictly necessary, but since this is the 2021 edition, we'll throw in this macro added to Emacs in 2016 as part of 25.1. Arthur Malabarba has a great post on thread-last.
Now that we've built out ar/scrape-links-from-clipboard-url function, let's make its content consumable!
The completing frameworks way
This is the 2021 edition, so power up your completion framework du jour and feed the output of ar/scrape-links-from-clipboard-url to our completion robots…
I'm heavily vested in ivy, but since we're using the built-in completing-read function, any completion framework like vertico, selectrum, helm, or ido should kick right in to give you extra powers.
(defun ar/view-completing-links-at-clipboard-url () "Scrape links from clipboard URL and open all in external browser." (interactive) (browse-url (completing-read "links: " (ar/scrape-links-from-clipboard-url))))
The auto-open way (use with caution)
Sometimes you just want to open every link posted in the comments and use your browser to discard, closing tabs as needed. The recent HN news instance wasn't one of these cases, with a whopping 398 links returned by our ar/scrape-links-from-clipboard-url.
Note: I capped the results to 5 in this gif/demo to prevent a Firefox tragedy (see seq-take).
In a case like Hacker News's, we don't want to surprise-attack the user and bomb their browser by opening a gazillion tabs, so let's give a little heads-up using y-or-n-p.
(defun ar/browse-links-at-clipboard-url () (interactive) (let ((links (ar/scrape-links-from-clipboard-url))) (when (y-or-n-p (format "Open all %d links? " (length links))) (mapc (lambda (link) (browse-url link)) links))))
The org way
My 2015 solution leveraged an org mode buffer to dump the fetched links. The org way is still my favorite. You can use whatever existing Emacs super powers you already have on top of the org buffer, including searching and filtering fueled by your favourite completion framework. I'm a fan of Oleh's swiper.
The 2021 implementation is mostly a tidy-up, removing some cruft, but also uses our new ar/scrape-links-from-clipboard-url function to filter and sort accordingly.
(require 'org) (defun ar/view-links-at-clipboard-url () "Scrape links from clipboard URL and dump to an org buffer." (interactive) (with-current-buffer (get-buffer-create "*links*") (org-mode) (erase-buffer) (mapc (lambda (link) (insert (org-make-link-string link) "\n")) (ar/scrape-links-from-clipboard-url)) (goto-char (point-min)) (switch-to-buffer (current-buffer))))
Emacs + community + packages + your own glue = awesome
To power our 2021 link scraper, we've used newer libraries included in more recent versions of Emacs, leveraged an older but solid HTML-parsing package, pulled in org mode (the epicenter of Emacs note-taking), dragged in our favorite completion framework, and tickled our handy browser all by smothering the lot with some elisp glue to make Emacs do exactly what we want. Emacs does rock.
gpg: decryption failed: No secret key (macOS)
gpg: decryption failed: No secret key
OMG! Where's my secret key gone!?
But but but, gpg –list-secret-keys says they're there. Puzzled…
Ray Oei's Stack Overflow answer solved the mystery for me: pinentry never got invoked, so likely something's up with the agent… Killing (and thus restaring) the gpg-agent did the trick:
gpgconf --kill gpg-agent
Thank you internet stranger. Balance restored.
Emacs plus –with-native-comp
I'm a big fan of Boris Buliga's Emacs Plus homebrew recipe for customizing and installing Emacs builds on macOS.
For a little while, I took a detour and built Emacs myself, so I could enable Andrea Corallo's fantastic native compilation. I documented the steps here. Though it was fairly straightforward, I did miss Emacs Plus's convenience.
I had been meaning to check back on Emacs Plus for native compilation support. Turns out, it was merged back in Dec 2020, and it works great!
Enabling native compilation is simple (just use –with-native-comp). As a bonus, you get all the Emacs Plus goodies. I'm loving –with-elrumo2-icon, enabling a spiffy icon to go with macOS Big Sur. –with-no-frame-refocus is also handy to avoid refocusing other frames when another one is closed.
In any case, here's the minimum needed to install Emacs Plus with native compilation support enabled:
brew tap d12frosted/emacs-plus brew install emacs-plus@28 --with-native-comp
Sit tight. Homebrew will build and install some chunky dependencies (including gcc and libgccjit).
Note: Your init.el needs tweaking to take advantage of native compilation. See my previous post for how I set mine, or go straight to my config.
Cycling window layouts with hammerspoon
Back in January, Patrik Collison tweeted about Rectangle's Todo mode. Rectangle looks great. Although I've not yet adopted it, Todo mode really resonates with me. I've been achieving similar functionality with hammerspoon.
Here's a quick and dirty function to cycle through my window layouts:
function reframeFocusedWindow() local win = hs.window.focusedWindow() local maximizedFrame = win:screen():frame() maximizedFrame.x = maximizedFrame.x + 15 maximizedFrame.y = maximizedFrame.y + 15 maximizedFrame.w = maximizedFrame.w - 30 maximizedFrame.h = maximizedFrame.h - 30 local leftFrame = win:screen():frame() leftFrame.x = leftFrame.x + 15 leftFrame.y = leftFrame.y + 15 leftFrame.w = leftFrame.w - 250 leftFrame.h = leftFrame.h - 30 local rightFrame = win:screen():frame() rightFrame.x = rightFrame.w - 250 + 15 rightFrame.y = rightFrame.y + 15 rightFrame.w = 250 - 15 - 15 rightFrame.h = rightFrame.h - 30 -- Make space on right if win:frame() == maximizedFrame then win:setFrame(leftFrame) return end -- Make space on left if win:frame() == leftFrame then win:setFrame(rightFrame) return end win:setFrame(maximizedFrame) end
A here's my ⌥-F binding to reframeFocusedWindow:
hs.hotkey.bind({"alt"}, "F", reframeFocusedWindow)
Flat Habits meets org agenda
UPDATE: Flat Habits now has its own page at flathabits.com.
Flat Habits v1.0.2 is out today, with habit-toggling now supported from the streak view.
Flat Habits runs on org, making it a great complement to Emacs and org agenda \o/
Flat Habits for iOS (powered by org)
UPDATE: Flat Habits now has its own page at flathabits.com.
No friction. No social. No analytics. No account. No cloud. No lock-in.
Why an app?
Tracking and accountability may help you develop positive habits. A simple habit-tracking app should make this easy. I'm not a habits expert, but got inspired by James Clear's Atomic Habits. Read that book if you're interested in the topic.
I wanted a frictionless habit tracker that gets out of the way, so I built one to my taste.
Sounds like a lot of work?
You mean habit tracking? It's not. I tried to make the app simple and focused. Mark a habit done whenever you do it. It's really encouraging to see your daily streaks grow. I really don't want to break them.
What kind of habits?
Any recurring habit you'd like to form like exercise, water the plants, read, make your bed, recycle, call grandma, yoga, cleaning, drink water, meditate, take a nap, make your lunch, journal, laundry, push-ups, sort out the dryer filter, floz, take your vitamins, take your meds, eat salad, eat fruit, practice a language, practice an instrument, go to bed early…
So it's like a task/todo app?
Nope. This app focuses solely on habits. Unlike todos/tasks, habits must happen regularly. If you don't water the plants, they will die. If you don't exercise regularly, you won't get the health benefits. Keep your habits separate from that long list of todos. You know, that panic-inducing list you're too afraid to look at.
Where is my data stored?
On your iPhone as a plain text file (in org mode format). You can view, edit, or migrate your data at any time (use export from the menu). You may also save it to a shared location, so you can access it from multiple devices/apps. Some of us like to use our beloved text editors (Emacs, Vim, VSCode, etc.) to poke at habits.
Got more questions?
I may not have the answer, but I can try. Ping me at flathabits*at*xenodium.com.
Privacy policy
No personal data is sent to any server, as there is no server component to this app. There are neither third party integrations, accounts, analytics, nor trackers in this app. All your data is kept on your iPhone, unless you choose a cloud provider to sync or store your data. See your cloud provider's privacy policy for details on how they may handle it.
If you choose to send feedback by email, you have the option to review and attach logs to help diagnose issues. If you'd like an email thread to be deleted, just ask.

Frictionless org habits on iOS
UPDATE: Flat Habits now has its own page at flathabits.com.
I've been wanting org to keep track of my daily habits for a little while. The catalyst: reading James Clear's wonderful Atomic Habits (along with plenty of lock-down inspiration).
As much as I live in Emacs and org mode, it just wasn't practical enough to rely on my laptop for tracking habits. I wanted less friction, so I've been experimenting with building a toy app for my needs. Naturally, org support was a strict requirement, so I could always poke at it from my beloved editor.
I've been using the app every day with success. The habits seem to be sticking, but equally important, it's been really fun to join the fabulous world of Emacs/Org with iOS/SwiftUI.
This is all very experimental1 and as mentioned on reddit (follow-up here) and twitter, the app isn't available on the App Store. I may consider publishing if there's enough interest, but in the mean time, you can reach out and install via TestFlight.
Send me an email address to flathabits*at*xenodium.com for a TestFlight invite.
2021-03-12 Update: Now with iOS Files app/sync integration
If you can sync your org file with your iPhone (ie. Drive/Dropbox/iCloud), and list it in the Files app, you should be able to open/edit1 with Flat Habits (that's the name now). With iOS Files integration, you should be able to sync your habits between your iPhone and your funky editor powering org mode2.

Emacs: mu4e icons
Recently spotted mu4e-marker-icons, which adds mu4e icons using all-the-icons.
Although I'm not currently using all-the-icons, it did remind me to take a look at mu4e's built-in variables to spiff up my email. It's pretty simple. Find the icons you like and set them as follows:
(setq mu4e-headers-unread-mark '("u" . "📩 ")) (setq mu4e-headers-draft-mark '("D" . "🚧 ")) (setq mu4e-headers-flagged-mark '("F" . "🚩 ")) (setq mu4e-headers-new-mark '("N" . "✨ ")) (setq mu4e-headers-passed-mark '("P" . "↪ ")) (setq mu4e-headers-replied-mark '("R" . "↩ ")) (setq mu4e-headers-seen-mark '("S" . " ")) (setq mu4e-headers-trashed-mark '("T" . "🗑️")) (setq mu4e-headers-attach-mark '("a" . "📎 ")) (setq mu4e-headers-encrypted-mark '("x" . "🔑 ")) (setq mu4e-headers-signed-mark '("s" . "🖊 "))

Swift package code coverage (plus Emacs overlay)
While playing around with Swift package manager, I had a quick look into code coverage options. Luckily, coverage reporting and exporting are supported out of the box (via llvm-cov).
Ensure tests are invoked as follows:
swift test --enable-code-coverage
A high level report can be generated with:
xcrun llvm-cov report .build/x86_64-apple-macosx/debug/FooPackageTests.xctest/Contents/MacOS/FooPackageTests \ -instr-profile=.build/x86_64-apple-macosx/debug/codecov/default.profdata -ignore-filename-regex=".build|Tests"
Filename Regions Missed Regions Cover Functions Missed Functions Executed Lines Missed Lines Cover -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- /tmp/Foo/Sources/Foo/Foo.swift 2 1 50.00% 2 1 50.00% 6 3 50.00% -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- TOTAL 2 1 50.00% 2 1 50.00% 6 3 50.00%
llvm-cov can export as lcov format:
xcrun llvm-cov export -format="lcov" .build/x86_64-apple-macosx/debug/FooPackageTests.xctest/Contents/MacOS/FooPackageTests -instr-profile=.build/x86_64-apple-macosx/debug/codecov/default.profdata -ignore-filename-regex=".build|Tests" > coverage.lcov
With the report in lcov format, we can look for an Emacs package to visualize coverage in source files. Found coverlay.el to require minimal setup. I was interested in highlighting only untested areas, so I set tested-line-background-color to nil:
(use-package coverlay :ensure t :config (setq coverlay:tested-line-background-color nil))
After installing coverlay, I enabled the minor mode via M-x coverlay-minor-mode, invoked M-x coverlay-watch-file to watch coverage.lcov for changes, and voilà!

Emacs: Rotate my macOS display
Every so often, I rotate my monitor (vertical vs horizontal) for either work or to watch a movie. macOS enables changing the display rotation via a dropdown menu (under Preferences > Displays > Rotation) where you can pick between Standard, 90°, 180°, and 270°. That's all fine, but what I'd really like is a quick way to toggle between my preferred two choices: Standard and 270°.
Unsurprisingly, I'd also like to invoke it as an interactive command via Emacs's M-x (see Emacs: connect my Bluetooth speaker). With narrowing frameworks like ivy, helm, and ido, invoking these commands is just a breeze.
Turns out, this was pretty simple to accomplish, thanks to Eric Nitardy's fb-rotate command line utility. All that's left to do is wrap it in a tiny elisp function hack, add the toggling logic, and voilà!
The screen capture goes a little funky when rotating the display, but you get the idea. It works better in person :)
…and here's the snippet:
(defun ar/display-toggle-rotation () (interactive) (require 'cl-lib) (cl-assert (executable-find "fb-rotate") nil "Install fb-rotate from https://github.com/CdLbB/fb-rotate") ;; # Display_ID Resolution ____Display_Bounds____ Rotation ;; 2 0x2b347692 1440x2560 0 0 1440 2560 270 [main] ;; From fb-rotate output, get the `current-rotation' from Column 7, row 1 zero-based. (let ((current-rotation (nth 7 (split-string (nth 1 (process-lines "fb-rotate" "-i")))))) (call-process-shell-command (format "fb-rotate -d 1 -r %s" (if (equal current-rotation "270") "0" "270")))))
Emacs: Clone git repo from clipboard
Cloning git repositories is a pretty common task. For me, it typically goes something like:
- Copy git repo URL from browser.
- Drop to Emacs eshell.
- Change current directory.
- Type "git clone ".
- Paste git repo URL.
- Run git command.
- Change directory to cloned repo.
- Open dired.
No biggie, but why go through the same steps every time? We can do better. We have a hyper malleable editor, so let's get it to grab the URL from clipboard and do its thing.
shell-command or async-shell-command can help in this space, but require additional work: change location, re-type command, what if directory already exists… This is Emacs, so we can craft the exact experience we want. I did take inspiration from shell-command to display the process buffer correctly (git progress, control codes, etc.) and landed on the following experience:
;; -*- lexical-binding: t -*- (defun ar/git-clone-clipboard-url () "Clone git URL in clipboard asynchronously and open in dired when finished." (interactive) (cl-assert (string-match-p "^\\(http\\|https\\|ssh\\)://" (current-kill 0)) nil "No URL in clipboard") (let* ((url (current-kill 0)) (download-dir (expand-file-name "~/Downloads/")) (project-dir (concat (file-name-as-directory download-dir) (file-name-base url))) (default-directory download-dir) (command (format "git clone %s" url)) (buffer (generate-new-buffer (format "*%s*" command))) (proc)) (when (file-exists-p project-dir) (if (y-or-n-p (format "%s exists. delete?" (file-name-base url))) (delete-directory project-dir t) (user-error "Bailed"))) (switch-to-buffer buffer) (setq proc (start-process-shell-command (nth 0 (split-string command)) buffer command)) (with-current-buffer buffer (setq default-directory download-dir) (shell-command-save-pos-or-erase) (require 'shell) (shell-mode) (view-mode +1)) (set-process-sentinel proc (lambda (process state) (let ((output (with-current-buffer (process-buffer process) (buffer-string)))) (kill-buffer (process-buffer process)) (if (= (process-exit-status process) 0) (progn (message "finished: %s" command) (dired project-dir)) (user-error (format "%s\n%s" command output)))))) (set-process-filter proc #'comint-output-filter)))
Updates
- Added lexical binding.
- Checks clipboard for ssh urls also.

Emacs: chaining org babel blocks
Recently wanted to chain org babel blocks. That is, aggregate separate source blocks and execute as one combined block.
I wanted the chaining primarily driven through header arguments as follows:
#+name: block-0 #+begin_src swift print("hello 0") #+end_src #+name: block-1 #+begin_src swift :include block-0 print("hello 1") #+end_src #+RESULTS: block-1 : hello 0 : hello 1
I didn't find the above syntax and behaviour supported out of the box (or didn't search hard enough?). Fortunately, this is our beloved and malleable editor, so we can always bend it our way! Wasn't quite sure how to go about it, so I looked at other babel packages for inspiration. ob-async was great for that.
Turns out, advicing org-babel-execute-src-block did the job:
(defun adviced:org-babel-execute-src-block (&optional orig-fun arg info params) (let ((body (nth 1 info)) (include (assoc :include (nth 2 info))) (named-blocks (org-element-map (org-element-parse-buffer) 'src-block (lambda (item) (when (org-element-property :name item) (cons (org-element-property :name item) item)))))) (while include (unless (cdr include) (user-error ":include without value" (cdr include))) (unless (assoc (cdr include) named-blocks) (user-error "source block \"%s\" not found" (cdr include))) (setq body (concat (org-element-property :value (cdr (assoc (cdr include) named-blocks))) body)) (setf (nth 1 info) body) (setq include (assoc :include (org-babel-parse-header-arguments (org-element-property :parameters (cdr (assoc (cdr include) named-blocks))))))) (funcall orig-fun arg info params))) (advice-add 'org-babel-execute-src-block :around 'adviced:org-babel-execute-src-block)
Before I built my own support, I did find that noweb got me most of what I needed, but required sprinkling blocks with placeholder references.
Combining :noweb and :prologue would have been a great match, if only prologue did expand the noweb reference. I'm sure there's an alternative I'm missing. Either way, it was fun to poke at babel blocks and build my own chaining support.
Emacs: quote wrap all in region
As I find myself moving more shell commands into Emacs interactive commands to create a Swift package/project, enrich dired's featureset, or search/play Music (macOS), I often need to take a single space-separated string, make an elisp list of strings, and feed it to functions like process-lines. No biggie, but I thought it'd be a fun little function to write: take the region and wrap all items in quotes. As a bonus, made it toggable.
(defun ar/toggle-quote-wrap-all-in-region (beg end) "Toggle wrapping all items in region with double quotes." (interactive (list (mark) (point))) (unless (region-active-p) (user-error "no region to wrap")) (let ((deactivate-mark nil) (replacement (string-join (mapcar (lambda (item) (if (string-match-p "^\".*\"$" item) (string-trim item "\"" "\"") (format "\"%s\"" item))) (split-string (buffer-substring beg end))) " "))) (delete-region beg end) (insert replacement)))
Emacs: org block complete and edit
I quickly got used to Emacs org block company completion. I did, however, almost always found myself running org-edit-special immediately after inserting completion. I use C-c ' for that. That's all fine, but it just felt redundant.
Why not automatically edit the source block in corresponding major mode after completion? I think I can also get used to that!
Or maybe the automatic approach is too eager? There's also a middle ground: ask immediately after.
Or maybe I don't want either in the end? Time will tell, but I now have all three options available:
(defcustom company-org-block-edit-mode 'auto "Customize whether edit mode, post completion was inserted." :type '(choice (const :tag "nil: no edit after insertion" nil) (const :tag "prompt: ask before edit" prompt) (const :tag "auto edit, no prompt" auto)))
The new option is now in the company-org-block snippet with my latest config.
Emacs: create a Swift package/project
Been playing around with Swift Package Manager (SPM). Creating a new Swift package (ie. project) is pretty simple.
To create a library package, we can use the following:
swift package init --type library
Alternatively, to create a command-line utility use:
swift package init --type executable
Turns out, there are a few options: empty, library, executable, system-module, manifest.
With a little elisp, we can write a completing function to quickly generate a Swift package/project without the need to drop to the shell.
Bonus: I won't have to look up SPM options if I ever forget them.

Improved Ctrl-p/Ctrl-n macOS movement
macOS supports many Emacs bindings (out of the box). You can, for example, press C-p and C-n to move the cursor up and down (whether editing text in Emacs or any other macOS app). Jacob Rus's Customizing the Cocoa Text System offers a more in-depth picture and also shows how to customize global macOS keybindings (via DefaultKeyBinding.dict).
In addition to moving Emacs point (cursor) up/down using C-p/C-n, I've internalized the same bindings to select an option from a list. Good Emacs examples of these are company mode and ivy.
Vertical cursor movement using Emacs bindings works well in most macOS apps, including forms and text boxes in web pages. However, selecting from a completion list doesn't quite work as expected. Although the binding is technically handled, it moves the cursor within the text widget, ignoring the suggested choices.
Atif Afzal's Use emacs key bindings everywhere has a solution for the ignored case. He uses Karabiner Elements to remap c-p and c-n to arrow-up and arrow-down.
It's been roughly a week since I started using the Karabiner remapping, and I've yet to find a case where a web page (or any other macOS app) did not respond to c-p and c-n to move selection from a list.
My ~/.config/karabiner/karabiner.json configuration is as follows:
{ "global": { "check_for_updates_on_startup": true, "show_in_menu_bar": true, "show_profile_name_in_menu_bar": false }, "profiles": [ { "complex_modifications": { "parameters": { "basic.simultaneous_threshold_milliseconds": 50, "basic.to_delayed_action_delay_milliseconds": 500, "basic.to_if_alone_timeout_milliseconds": 1000, "basic.to_if_held_down_threshold_milliseconds": 500, "mouse_motion_to_scroll.speed": 100 }, "rules": [ { "description": "Ctrl+p/Ctrl+n to arrow up/down", "manipulators": [ { "from": { "key_code": "p", "modifiers": { "mandatory": [ "control" ] } }, "to": [ { "key_code": "up_arrow" } ], "conditions": [ { "type": "frontmost_application_unless", "bundle_identifiers": [ "^org\\.gnu\\.Emacs" ] } ], "type": "basic" }, { "from": { "key_code": "n", "modifiers": { "mandatory": [ "control" ] } }, "to": [ { "key_code": "down_arrow" } ], "conditions": [ { "type": "frontmost_application_unless", "bundle_identifiers": [ "^org\\.gnu\\.Emacs" ] } ], "type": "basic" } ] } ] }, "devices": [], "fn_function_keys": [], "name": "Default profile", "parameters": { "delay_milliseconds_before_open_device": 1000 }, "selected": true, "simple_modifications": [], "virtual_hid_keyboard": { "country_code": 0, "mouse_key_xy_scale": 100 } } ] }
Bonus (C-g to exit)
Pressing Esc often dismisses or cancels macOS windows, menus, etc. This is also the case for web pages. As an Emacs user, I'm pretty used to pressing C-g to cancel, quit, or exit things. With that in mind, mapping C-g to Esc is surprisingly useful outside of Emacs. Here's the relevant Karabiner C-g binding for that:
{ "description": "Ctrl+G to Escape", "manipulators": [ { "description": "emacs like escape", "from": { "key_code": "g", "modifiers": { "mandatory": [ "left_control" ] } }, "to": [ { "key_code": "escape" } ], "conditions": [ { "type": "frontmost_application_unless", "bundle_identifiers": [ "^org\\.gnu\\.Emacs" ] } ], "conditions": [ { "type": "frontmost_application_unless", "bundle_identifiers": [ "^org\\.gnu\\.Emacs" ] } ], "type": "basic" } ] }
UPDATE: Ensure bindings are only active when Emacs is not active.
Basmati rice pudding recipe
Combine in a pot
- 2/3 cup of basmati rice
- 400 ml of coconut milk
- 4 cups of milk [1]
- 3 tablespoons of honey [2]
- 1/4 teaspoon of crushed cardamom seeds [3]
- 1/8 teaspoon of salt
Simple. Combine all ingredients in a pot.
[1] Been using powder milk since lockdown, end-result's been tasty. [2] Only tried raw honey so far. [3] Can likely use ground cardamom. I enjoy the scents while crushing.
Boil and simmer
Bring ingredients to a boil and simmer at low heat for 45 minutes. Stir occasionally.
Mix in butter
- 1 tablespoon of butter.
Turn stove off, add a tablespoon of butter, and mix in.
Serve warm or cold
After mixing in the butter, the rice pudding is done. You can serve warm or cold.
Garnish (optional)
- Pistachios
- Cinnamon
Optionally garnish with either pistachios or cinnamon (or both).
Adding images to pdfs (macOS)
The macOS Preview app does a great job inserting signatures to existing pdfs. I was hoping it could overlay images just as easily. Doesn't look like it's possible, without exporting/reimporting to image formats and losing pdf structure. Did I miss something?
In any case, I found formulatepro. Dormant at Google Code Archive, but also checked in to github. With a tiny patch, it builds and runs on Catalina. One can easily insert an image via "File > Place Image…".

Emacs: search/play Music (macOS)
While trying out macOS's Music app to manage offline media, I wondered if I could easily search and control playback from Emacs. Spoiler alert: yes it can be done and fuzzy searching music is rather gratifying.
Luckily, the hard work's already handled by pytunes, a command line interface to macOS's iTunes/Music app. We add ffprobe and some elisp glue to the mix, and we can generate an Emacs media index.
Indexing takes roughly a minute per 1000 files. Prolly suboptimal, but I don't intend to re-index frequently. For now, we can use a separate process to prevent Emacs from blocking, so we can get back to playing tetris from our beloved editor:
(defun musica-index () "Indexes Music's tracks in two stages: 1. Generates \"Tracks.sqlite\" using pytunes (needs https://github.com/hile/pytunes installed). 2. Caches an index at ~/.emacs.d/.musica.el." (interactive) (message "Indexing music... started") (let* ((now (current-time)) (name "Music indexing") (buffer (get-buffer-create (format "*%s*" name)))) (with-current-buffer buffer (delete-region (point-min) (point-max))) (set-process-sentinel (start-process name buffer (file-truename (expand-file-name invocation-name invocation-directory)) "--quick" "--batch" "--eval" (prin1-to-string `(progn (interactive) (require 'cl-lib) (require 'seq) (require 'map) (message "Generating Tracks.sqlite...") (process-lines "pytunes" "update-index") ;; Generates Tracks.sqlite (message "Generating Tracks.sqlite... done") (defun parse-tags (path) (with-temp-buffer (if (eq 0 (call-process "ffprobe" nil t nil "-v" "quiet" "-print_format" "json" "-show_format" path)) (map-elt (json-parse-string (buffer-string) :object-type 'alist) 'format) (message "Warning: Couldn't read track metadata for %s" path) (message "%s" (buffer-string)) (list (cons 'filename path))))) (let* ((paths (process-lines "sqlite3" (concat (expand-file-name "~/") "Music/Music/Music Library.musiclibrary/Tracks.sqlite") "select path from tracks")) (total (length paths)) (n 0) (records (seq-map (lambda (path) (let ((tags (parse-tags path))) (message "%d/%d %s" (setq n (1+ n)) total (or (map-elt (map-elt tags 'tags) 'title) "No title")) tags)) paths))) (with-temp-buffer (prin1 records (current-buffer)) (write-file "~/.emacs.d/.musica.el" nil)))))) (lambda (process state) (if (= (process-exit-status process) 0) (message "Indexing music... finished (%.3fs)" (float-time (time-subtract (current-time) now))) (message "Indexing music... failed, see %s" buffer))))))
Once media is indexed, we can feed it to ivy for that narrowing-down fuzzy-searching goodness! It's worth mentioning the truncate-string-to-width function. Super handy for truncating strings to a fixed width and visually organizing search results in columns.
(defun musica-search () (interactive) (cl-assert (executable-find "pytunes") nil "pytunes not installed") (let* ((c1-width (round (* (- (window-width) 9) 0.4))) (c2-width (round (* (- (window-width) 9) 0.3))) (c3-width (- (window-width) 9 c1-width c2-width))) (ivy-read "Play: " (mapcar (lambda (track) (let-alist track (cons (format "%s %s %s" (truncate-string-to-width (or .tags.title (file-name-base .filename) "No title") c1-width nil ?\s "…") (truncate-string-to-width (propertize (or .tags.artist "") 'face '(:foreground "yellow")) c2-width nil ?\s "…") (truncate-string-to-width (propertize (or .tags.album "") 'face '(:foreground "cyan1")) c3-width nil ?\s "…")) track))) (musica--index)) :action (lambda (selection) (let-alist (cdr selection) (process-lines "pytunes" "play" .filename) (message "Playing: %s [%s] %s" (or .tags.title (file-name-base .filename) "No title") (or .tags.artist "No artist") (or .tags.album "No album"))))))) (defun musica--index () (with-temp-buffer (insert-file-contents "~/.emacs.d/.musica.el") (read (current-buffer))))
The remaining bits are straigtforward. We add a few interactive functions to control playback:
(defun musica-info () (interactive) (let ((raw (process-lines "pytunes" "info"))) (message "%s [%s] %s" (string-trim (string-remove-prefix "Title" (nth 3 raw))) (string-trim (string-remove-prefix "Artist" (nth 1 raw))) (string-trim (string-remove-prefix "Album" (nth 2 raw)))))) (defun musica-play-pause () (interactive) (cl-assert (executable-find "pytunes") nil "pytunes not installed") (process-lines "pytunes" "play") (musica-info)) (defun musica-play-next () (interactive) (cl-assert (executable-find "pytunes") nil "pytunes not installed") (process-lines "pytunes" "next")) (defun musica-play-next-random () (interactive) (cl-assert (executable-find "pytunes") nil "pytunes not installed") (process-lines "pytunes" "shuffle" "enable") (let-alist (seq-random-elt (musica--index)) (process-lines "pytunes" "play" .filename)) (musica-info)) (defun musica-play-previous () (interactive) (cl-assert (executable-find "pytunes") nil "pytunes not installed") (process-lines "pytunes" "previous"))
Finally, if we want some convenient keybindings, we can add something like:
(global-set-key (kbd "C-c m SPC") #'musica-play-pause) (global-set-key (kbd "C-c m i") #'musica-info) (global-set-key (kbd "C-c m n") #'musica-play-next) (global-set-key (kbd "C-c m p") #'musica-play-previous) (global-set-key (kbd "C-c m r") #'musica-play-next-random) (global-set-key (kbd "C-c m s") #'musica-search)
Hooray! Controlling music is now an Emacs keybinding away: \o/

UPDATE1: Installing pytunes with pip3 install pytunes didn't just work for me. Instead, I cloned and installed as:
git clone https://github.com/hile/pytunes pip3 install file:///path/to/pytunes pip3 install pytz brew install libmagic
UPDATE2: Checked in to dot files.

Smarter Swift snippets
Jari Safi published a wonderful Emacs video demoing python yasnippets in action. The constructor snippet, automatically setting ivars, is just magical. I wanted it for Swift!
I took a look at the __init__ snippet from Jorgen Schäfer's elpy. It uses elpy-snippet-init-assignments to generate the assignments.
With small tweaks, we can get the same action going on for Swift \o/
init.yasnippet:
# -*- mode: snippet -*- # name: init with assignments # key: init # -- init(${1:, args}) { ${1:$(swift-snippet-init-assignments yas-text)} } $0
.yas-setup.el:
(defun swift-snippet-init-assignments (arg-string) (let ((indentation (make-string (save-excursion (goto-char start-point) (current-indentation)) ?\s))) (string-trim (mapconcat (lambda (arg) (if (string-match "^\\*" arg) "" (format "self.%s = %s\n%s" arg arg indentation))) (swift-snippet-split-args arg-string) "")))) (defun swift-snippet-split-args (arg-string) (mapcar (lambda (x) (if (and x (string-match "\\([[:alnum:]]*\\):" x)) (match-string-no-properties 1 x) x)) (split-string arg-string "[[:blank:]]*,[[:blank:]]*" t)))
Swift package manager build for iOS
While playing around with Swift package manager, it wasn't immediately obvious how to build for iOS from the command line. The default behaviour of invoking swift build is to build for the host. In my case, macOS. In any case, this was it:
swift build -Xswiftc "-sdk" -Xswiftc "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator13.0.sdk" -Xswiftc "-target" -Xswiftc "x86_64-apple-ios13.0-simulator"
ps. Can get the SDK path with:
xcrun --sdk iphonesimulator --show-sdk-path

Trying out gccemacs on macOS
UPDATE: I'm no longer using these steps. See Emacs plus –with-native-comp for an easier alternative.
Below are the instructions I use to build Andrea Corallo's gccemacs on macOS. It is based on Allen Dang's handy instructions plus some changes of my own.
Install gcc and libgccjit via homebrew
brew install gcc libgccjit
Save configure script
Create configure-gccemacs.sh
#!/bin/bash set -o nounset set -o errexit # Configures Emacs for building native comp support # http://akrl.sdf.org/gccemacs.html readonly GCC_DIR="$(realpath $(brew --prefix libgccjit))" [[ -d $GCC_DIR ]] || { echo "${GCC_DIR} not found"; exit 1; } readonly SED_DIR="$(realpath $(brew --prefix gnu-sed))" [[ -d $SED_DIR ]] || { echo "${SED_DIR} not found"; exit 1; } readonly GCC_INCLUDE_DIR=${GCC_DIR}/include [[ -d $GCC_INCLUDE_DIR ]] || { echo "${GCC_INCLUDE_DIR} not found"; exit 1; } readonly GCC_LIB_DIR=${GCC_DIR}/lib/gcc/10 [[ -d $GCC_LIB_DIR ]] || { echo "${GCC_LIB_DIR} not found"; exit 1; } export PATH="${SED_DIR}/libexec/gnubin:${PATH}" export CFLAGS="-O2 -I${GCC_INCLUDE_DIR}" export LDFLAGS="-L${GCC_LIB_DIR} -I${GCC_INCLUDE_DIR}" export LD_LIBRARY_PATH="${GCC_LIB_DIR}" export DYLD_FALLBACK_LIBRARY_PATH="${GCC_LIB_DIR}" echo "Environment" echo "-----------" echo PATH: $PATH echo CFLAGS: $CFLAGS echo LDFLAGS: $LDFLAGS echo DYLD_FALLBACK_LIBRARY_PATH: $DYLD_FALLBACK_LIBRARY_PATH echo "-----------" ./autogen.sh ./configure \ --prefix="$PWD/nextstep/Emacs.app/Contents/MacOS" \ --enable-locallisppath="${PWD}/nextstep/Emacs.app/Contents/MacOS" \ --with-mailutils \ --with-ns \ --with-imagemagick \ --with-cairo \ --with-modules \ --with-xml2 \ --with-gnutls \ --with-json \ --with-rsvg \ --with-native-compilation \ --disable-silent-rules \ --disable-ns-self-contained \ --without-dbus
Make it executable
chmod +x configure-gccemacs.sh
Clone Emacs source
git clone --branch master https://github.com/emacs-mirror/emacs gccemacs
Configure build
cd gccemacs
../configure-gccemacs.sh
Native lisp compiler found?
Verify native lisp compiler is found:
Does Emacs have native lisp compiler? yes
Build
Put those cores to use. Find out how many you got with:
sysctl hw.logicalcpu
hw.logicalcpu: 4
Ok so build with:
make -j4 NATIVE_FAST_BOOT=1
cp -r lisp nextstep/Emacs.app/Contents/Resources/
cp -r native-lisp nextstep/Emacs.app/Contents
make install
Note: Using NATIVE_FAST_BOOT=1 significantly improves build time (totalling between 20-30 mins, depending on your specs). Without it, the build can take hours.
The macOS app build (under nextstep/Emacs.app) is ready, but read on before launching.
Remove ~/emacs.d
You likely want to start with a clean install, byte-compiling all packages with the latest Emacs version. In any case, rename ~/emacs.d (for backup?) or remove ~/emacs.d.
init.el config
Ensure exec-path includes the script's "–prefix=" value, LIBRARY_PATH points to gcc's lib dir, and finally set comp-deferred-compilation. I wrapped the snippet in my exec-path-from-shell config, but setting early in init.el should be enough.
(use-package exec-path-from-shell :ensure t :config (exec-path-from-shell-initialize) (if (and (fboundp 'native-comp-available-p) (native-comp-available-p)) (progn (message "Native comp is available") ;; Using Emacs.app/Contents/MacOS/bin since it was compiled with ;; ./configure --prefix="$PWD/nextstep/Emacs.app/Contents/MacOS" (add-to-list 'exec-path (concat invocation-directory "bin") t) (setenv "LIBRARY_PATH" (concat (getenv "LIBRARY_PATH") (when (getenv "LIBRARY_PATH") ":") ;; This is where Homebrew puts gcc libraries. (car (file-expand-wildcards (expand-file-name "~/homebrew/opt/gcc/lib/gcc/*"))))) ;; Only set after LIBRARY_PATH can find gcc libraries. (setq comp-deferred-compilation t)) (message "Native comp is *not* available")))
Launch Emacs.app
You're good to go. Open Emacs.app via finder or shell:
open nextstep/Emacs.app
Deferred compilation logs
After setting comp-deferred-compilation (in init.el config section), .elc files should be asyncronously compiled. Function definition should be updated to native compiled equivalent.
Look out for an Async-native-compile-log buffer. Should have content like:
Compiling .emacs.d/elpa/moody-20200514.1946/moody.el... Compiling .emacs.d/elpa/minions-20200522.1052/minions.el... Compiling .emacs.d/elpa/persistent-scratch-20190922.1046/persistent-scratch.el... Compiling .emacs.d/elpa/which-key-20200721.1927/which-key.el... ...
Can also check for .eln files:
find ~/.emacs.d -iname *.eln | wc -l
149
UPDATE1: Added Symlink Emacs.app/Contents/eln-cache section for update 11.
UPDATE2: Noted using NATIVE_FAST_BOOT makes the build much faster.
UPDATE3: Removed symlinks and copied content instead. This simplifies things. Inspired by Ian Wahbe's build-emacs.sh.
UPDATE4: Removed homebrew recipe patching. Thanks to Dmitry Shishkin's instructions.
UPDATE5: Use new flag –with-native-compilation and master branch.
SwiftUI macOS desk clock
For time display, I've gone back and forth between an always-displayed macOS's menu bar to an auto-hide menu bar, and letting Emacs display the time. Neither felt great nor settled.
With some tweaks, Paul Hudson's How to use a timer with SwiftUI, led me to build a simple desk clock. Ok, let's not get fancy. It's really just an always-on-top floating window, showing a swiftUI label, but hey I like the minimalist feel ;)
Let's see if it sticks around or it gets in the way… Either way, here's standalone snippet. Run with swift deskclock.swift.
import Cocoa import SwiftUI let application = NSApplication.shared let appDelegate = AppDelegate() NSApp.setActivationPolicy(.regular) application.delegate = appDelegate application.mainMenu = NSMenu.makeMenu() application.run() struct ClockView: View { @State var time = "--:--" let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect() var body: some View { GeometryReader { geometry in VStack { Text(time) .onReceive(timer) { input in let formatter = DateFormatter() formatter.dateFormat = "HH:mm" time = formatter.string(from: input) } .font(.system(size: 40)) .padding() }.frame(width: geometry.size.width, height: geometry.size.height) .background(Color.black) .cornerRadius(10) .frame(maxWidth: .infinity, maxHeight: .infinity) } } } extension NSWindow { static func makeWindow() -> NSWindow { let window = NSWindow( contentRect: NSRect.makeDefault(), styleMask: [.closable, .miniaturizable, .resizable, .fullSizeContentView], backing: .buffered, defer: false) window.level = .floating window.setFrameAutosaveName("everclock") window.collectionBehavior = [.canJoinAllSpaces, .stationary, .ignoresCycle, .fullScreenPrimary] window.makeKeyAndOrderFront(nil) window.isMovableByWindowBackground = true window.titleVisibility = .hidden window.backgroundColor = .clear return window } } class AppDelegate: NSObject, NSApplicationDelegate { var window = NSWindow.makeWindow() var hostingView: NSView? func applicationDidFinishLaunching(_ notification: Notification) { hostingView = NSHostingView(rootView: ClockView()) window.contentView = hostingView NSApp.activate(ignoringOtherApps: true) } } extension NSRect { static func makeDefault() -> NSRect { let initialMargin = CGFloat(60) let fallback = NSRect(x: 0, y: 0, width: 100, height: 150) guard let screenFrame = NSScreen.main?.frame else { return fallback } return NSRect( x: screenFrame.maxX - fallback.width - initialMargin, y: screenFrame.maxY - fallback.height - initialMargin, width: fallback.width, height: fallback.height) } } extension NSMenu { static func makeMenu() -> NSMenu { let appMenu = NSMenuItem() appMenu.submenu = NSMenu() appMenu.submenu?.addItem( NSMenuItem( title: "Quit \(ProcessInfo.processInfo.processName)", action: #selector(NSApplication.terminate(_:)), keyEquivalent: "q" )) let mainMenu = NSMenu(title: "Main Menu") mainMenu.addItem(appMenu) return mainMenu } }

Emacs, search hackingwithswift.com
Paul Hudson authors excellent Swift material at hackingwithswift.com. I regularly land on the site while searching for snippets from the browser. I was wondering if I could search for snippets directly from Emacs.
Turns out, hackingwithswift uses a JSON HTTP request for querying code examples. With this in mind, we can use ivy-read like Oleh Krehel's counsel-search and search for Swift snippets from our favorite editor:
(require 'request) (require 'json) (defun ar/counsel-hacking-with-swift-search () "Ivy interface to query hackingwithswift.com." (interactive) (ivy-read "hacking with swift: " (lambda (input) (or (ivy-more-chars) (let ((request-curl-options (list "-H" (string-trim (url-http-user-agent-string))))) (request "https://www.hackingwithswift.com/example-code/search" :type "GET" :params (list (cons "search" input)) :parser 'json-read :success (cl-function (lambda (&key data &allow-other-keys) (ivy-update-candidates (mapcar (lambda (item) (let-alist item (propertize .title 'url .url))) data))))) 0))) :action (lambda (selection) (browse-url (concat "https://www.hackingwithswift.com" (get-text-property 0 'url selection)))) :dynamic-collection t :caller 'ar/counsel-hacking-with-swift-search))
Preview SwiftUI layouts using Emacs org blocks
✨ UPDATE: The snippets in this post are outdated. See ob-swiftui for better SwiftUI babel support. ✨
Chris Eidhof twitted a handy snippet that enables quickly bootstrapping throwaway SwiftUI code. It can be easily integrated into other tools for rapid experimentation.
Being a SwiftUI noob, I could use some SwiftUI integration with my editor of choice. With some elisp glue and a small patch, Chris's snippet can be used to generate SwiftUI inline previews using Emacs org babel. This is particularly handy for playing around with SwiftUI layouts.
We can piggyback ride off zweifisch's ob-swift by advicing org-babel-execute:swift to inject the org source block into the bootstrapping snippet. We also add a hook to org-babel-after-execute-hook to automatically refresh the inline preview.
If you're a use-package user, the following snippet should make things fairly self-contained (if you have melpa set up already).

Snippet also at github gist and included in my emacs config.
UPDATE: See ob-swiftui for a better version of babel SwiftUI support.
Once the snippet is evaluated, we're ready to use in an org babel block. We introduced the :swiftui header param to switch between inline static preview and interactive mode.
To try out an inline preview, create a new org file (eg. swiftui.org) and a source block like:
#+begin_src swift :results file :swiftui preview VStack(spacing: 10) { HStack(spacing: 10) { Rectangle().fill(Color.yellow) Rectangle().fill(Color.green) } Rectangle().fill(Color.blue) HStack(spacing: 10) { Rectangle().fill(Color.green) Rectangle().fill(Color.yellow) } } .frame(maxWidth: .infinity, maxHeight: .infinity) #+end_src
#+results:
Place the cursor anywhere inside the source block (#+begin_src/#+end_src) and press C-c C-c (or M-x org-ctrl-c-ctrl-c).
To run interactively, change the :swiftui param to interactive and press C-c C-c (or M-x org-ctrl-c-ctrl-c). When running interactively, press "q" (without ⌘) to quit the Swift app.

Update
- Tweaked the snippet to make it more self-contained and made the steps more reproducible. Need to work out how to package things to make them more accessible. May be best to contribute as a patch to ob-swift and we can avoid the icky advice-add.
- Thanks to Chris Eidhof for PNG support (instead of TIFF). Also TIL Swift's print has got a terminator param.
Open Emacs elfeed links in the background
Christopher Wellons's elfeed is a wonderful Emacs rss reader. In Mike Zamansky's Using Emacs 72 - Customizing Elfeed video, he highlights a desire to open elfeed entries in the background. That is, open the current rss entry (or selected entries) without shifting focus from Emacs to your browser. This behaviour is somewhat analogous to ⌘-clicking/ctrl-clicking on multiple links in the browser without losing focus.
I've been wanting elfeed to open links in the background for some time. Zamansky's post was a great nudge to look into it. He points to the relevant elfeed-search-browse-url function, re-implemented to suit his needs. In a similar spirit, I wrote a function to open the current rss entry (or selected entries) in the background.
I'm running macOS, so I took a look at browse-url-default-macosx-browser to get an idea of how URLs are opened. Simple. It let's macOS handle it via the "open" command, invoked through start process. Looking at open's command-line options, we find –background which "does not bring the application to the foreground."
open --background http://xenodium.com
"b" is already bound to elfeed-search-browse-url, so in our snippet we'll bind "B" to our new background function, giving us some flexibility:
(use-package elfeed :ensure t :bind (:map elfeed-search-mode-map ("B" . ar/elfeed-search-browse-background-url)) :config (defun ar/elfeed-search-browse-background-url () "Open current `elfeed' entry (or region entries) in browser without losing focus." (interactive) (let ((entries (elfeed-search-selected))) (mapc (lambda (entry) (assert (memq system-type '(darwin)) t "open command is macOS only") (start-process (concat "open " (elfeed-entry-link entry)) nil "open" "--background" (elfeed-entry-link entry)) (elfeed-untag entry 'unread) (elfeed-search-update-entry entry)) entries) (unless (or elfeed-search-remain-on-entry (use-region-p)) (forward-line)))))
Maybe xdg-open does a similar thing on linux (I've not looked). Ping me if you have a linux solution and I can update the function.
Happy Emacsing.
ps. I noticed elfeed uses browse-url-generic if elfeed-search-browse-url's is invoked with a prefix. Setting browse-url-generic-program and browse-url-generic-args to use background options may be a more generic solution. For now, a custom function does the job.

Enrich Emacs dired's batching toolbox
Update
I now use dwim-shell-command, which reduces the logic to:
(defun dwim-shell-commands-image-to-jpg () "Convert all marked images to jpg(s)." (interactive) (dwim-shell-command-on-marked-files "Convert to jpg" "convert -verbose '<<f>>' '<<fne>>.jpg'" :utils "convert"))
Original post
Shell one-liners are super handy for batch-processing files. Say you'd like to convert a bunch of images from HEIC to jpg, you could use something like:
for f in *.HEIC ; do convert "$f" "${f%.*}.jpg"; done
Save the one-liner (or memorize it) and pull it from your toolbox next time you need it. This is handy as it is, but Emacs dired is just a file-management powerhouse. Its dired-map-over-marks function is just a few elisp lines away from enabling all sorts of batch processing within your dired buffers.
Dired already enables selecting and deselecting files using all sorts of built-in mechanisms (dired-mark-files-regexp, find-name-dired, etc) or wonderful third-party packages like Matus Goljer's dired-filters.
Regardless of how you selected your files, here's a snippet to run ImageMagick's convert on a bunch of selected files:
;;; -*- lexical-binding: t; -*- (defun ar/dired-convert-image (&optional arg) "Convert image files to other formats." (interactive "P") (assert (or (executable-find "convert") (executable-find "magick.exe")) nil "Install imagemagick") (let* ((dst-fpath) (src-fpath) (src-ext) (last-ext) (dst-ext)) (mapc (lambda (fpath) (setq src-fpath fpath) (setq src-ext (downcase (file-name-extension src-fpath))) (when (or (null dst-ext) (not (string-equal dst-ext last-ext))) (setq dst-ext (completing-read "to format: " (seq-remove (lambda (format) (string-equal format src-ext)) '("jpg" "png"))))) (setq last-ext dst-ext) (setq dst-fpath (format "%s.%s" (file-name-sans-extension src-fpath) dst-ext)) (message "convert %s to %s ..." (file-name-nondirectory dst-fpath) dst-ext) (set-process-sentinel (if (string-equal system-type "windows-nt") (start-process "convert" (generate-new-buffer (format "*convert %s*" (file-name-nondirectory src-fpath))) "magick.exe" "convert" src-fpath dst-fpath) (start-process "convert" (generate-new-buffer (format "*convert %s*" (file-name-nondirectory src-fpath))) "convert" src-fpath dst-fpath)) (lambda (process state) (if (= (process-exit-status process) 0) (message "convert %s ✔" (file-name-nondirectory dst-fpath)) (message "convert %s ❌" (file-name-nondirectory dst-fpath)) (message (with-current-buffer (process-buffer process) (buffer-string)))) (kill-buffer (process-buffer process))))) (dired-map-over-marks (dired-get-filename) arg))))
The snippet can be shorter, but wouldn't be as friendly. We ask users to provide desired image format, spawn separate processes (avoids blocking Emacs), and generate a basic report. Also adds support for Windows.
BEWARE
The snippet isn't currently capping the number of processes, but hey we can revise in the future…
Update
Thanks to Philippe Beliveau for pointing out a bug in snippet (now updated) and changes to make it Windows compatible.

Emacs: connect my Bluetooth speaker
Connecting and disconnecting bluetooth devices on macOS is fairly simple: use the menu bar utility.
But could we make it quicker from our beloved editor?
Turns out with a little elisp glue, we can fuzzy search our Bluetooth devices and toggle connections. We can use Oleh Krehel's ivy-read for fuzzy searching and Felix Lapalme's nifty BluetoothConnector to list devices and toggle Bluetooth connections.
As a bonus, we can make it remember the last selected device, so you can quickly toggle it again.
(defun ar/ivy-bluetooth-connect () "Connect to paired bluetooth device." (interactive) (assert (string-equal system-type "darwin") nil "macOS only. Sorry :/") (assert (executable-find "BluetoothConnector") nil "Install BluetoothConnector from https://github.com/lapfelix/BluetoothConnector") (ivy-read "(Dis)connect: " (seq-map (lambda (item) (let* ((device (split-string item " - ")) (mac (nth 0 device)) (name (nth 1 device))) (propertize name 'mac mac))) (seq-filter (lambda (line) ;; Keep lines like: af-8c-3b-b1-99-af - Device name (string-match-p "^[0-9a-f]\\{2\\}" line)) (with-current-buffer (get-buffer-create "*BluetoothConnector*") (erase-buffer) ;; BluetoothConnector exits with 64 if no param is given. ;; Invoke with no params to get a list of devices.

Neapolitan pizza recipe
Full disclosure: I'm a complete noob at making pizza. It's my second pizza, but hey, it was tasty and fun to make! Making pizza at home is not as far-fetched as I initially thought.
UPDATES:
I've made this recipe a couple of times. Made two improvements worth mentioning.
Flan tin / quiche pan
My first pizzas were rectangular, matching the baking tray shape, but I really wanted round pies. I found a quiche pan at home and gave that a try. Worked pretty well. The dish bottom comes up, which is pretty handy.
Double baking
Bake in two stages:
- Bake the pizza for 6 minutes (without the mozarella) at bottom of oven.
- Add mozzarella and make for 4 minutes at top of the oven.
Recipe
Ok, on to the recipe now…
Dissolve the yeast
- 7g of yeast.
- 325ml of lukewarm water.
Dissolve the yeast in the lukewarm water.
Mixing the dough
- 500g of flour.
- 1 teaspoon of salt.
Gradually add flour to the yeast and water mix, using the bottom of a spoon to work it until smooth (no lumps). The dough will be very sticky at first. Stay faithful to the spoon. It'll work. BBC's How to make pizza like a Neapolitan master has a great demo. I followed the dough technique.
Kneading the dough
Sprinkle some flour on the table and knead the dough (punch, stretch, and fold many times) from previous step. Eventually, the dough will hold its shape.
Make 4 balls
Roll the dough into a cylinder and cut into 4 pieces. Make 4 balls.
Make the tomato sauce
- 500g of passata.
- 3 cloves of garlic.
I love garlic. Who doesn't? Slice the garlic finely and combine with the passata in a class jar. Shake it a little. Garlic and passata. That's your sauce.
Cover for 2 hours
Place the 4 dough balls into a container and cover with a damp cloth for 2 hours. You can make 4 pizzas.
*Rookie mistake: I should have used a bigger container. The balls grew and merged.
Preheat oven
Preheat the oven at 250°C.
Stretch base
Sprinkle more flour on table prior to shaping the dough. Place ball on table, flatten. Flip over, flatten again. Gradually stretch until you have the shape and thickness desired.
Place base on baking tray
- Semolina
- Aluminium foil
Line up the tray with some aluminium foil. Before transferring the base on to the baking tray, sprinkle semolina (or breadcrumbs) on the foil (it helps prevent the dough from sticking).
Toppings
- Tomato sauce.
- Salt.
- Olive oil.
- Parmesan cheese.
- 125g of Mozzarella cheese.
- Fresh basil.
Spread some of the tomato sauce with a spoon. Sprinkle salt, olive oil, and parmesan cheese. Break the mozzarella into pieces and spread throughout. Add some basil leaves. Your basic margherita pizza is now ready for the oven.
Bake pizza
Place the tray in the oven for 10 minutes. This worked for my oven, which goes up to 250°C. Either way, keep an eye on it.
Post baking toppings
- Anchovies.
Controversial, but I really like anchovies. Add them post-baking and you're good to go. Enjoy your pizza.

mu/mu4e 1.4 released
mu/mu4e 1.4 is out. About a week ago, I built and installed its pre-release version (1.3.10) and noted build steps on macOS. It's been working great for me. Today, I updated to 1.4.
I was keen to try the new release out. I had been experiencing a short delay immediately after syncing/indexing mail. An initial investigation pointed to contact syncing, but I didn't dig further. The 1.4 release notes had a promising entry:
In many cases, `mu4e' used to receive all contacts after each indexing operation; this was slow for some users, so we have updated this to only get the contacts that have changed since the last round.
After upgrading. The delay is gone for me \o/
Note: there are a few config tweaks needed for the 1.4 upgrade, but these are well-documented in the release notes. For me, it primarily consisted of:
- Swapping elisp mu4e-maildir var for mu init –maildir path/to/local/IMAP.
- Swapping elisp mu4e-user-mail-address-list for mu init –my-address address1@domain.com –my-address address2@domain.com.
- Disabling mu4e-maildirs-extension (not yet compatible with mu 1.4). No issues here, since I hardly ever look at the mu4e-main buffer. I have global binding to my unread messages that looks a little something like this:
(defun ar/mu4e-view-unread-messages () (interactive) (mu4e-headers-search-bookmark (concat "flag:unread AND " "flag:unread AND " "NOT flag:trashed AND " "(maildir:/box1/INBOX OR " "maildir:/box2/INBOX)")))

Emacs's counsel-M-x meets multiple cursors
I'm a fan of Magnar Sveen's multiple cursors Emacs implementation. It's just so fun to use and works very well with commands bound to my favorite keys.
Every now and then I'd like to execute extended commands on all cursors, but they have no keys bound to them. If you're an ivy/counsel fan like me (and all packages by Abo Abo), you use counsel-M-x to invoke commands. However, counsel-M-x doesn't support multiple cursors out of the box. Luckily, this is Emacs and we can fix that…
Back in December 2019, I made a note to revisit u/snippins1987's weekly tip to pair helm-M-x with multiple cursors. Finally got back to it. With a few changes, we can also make the snippet work with counsel-M-x \o/.
(defun adviced:counsel-M-x-action (orig-fun &rest r) "Additional support for multiple cursors." (apply orig-fun r) (let ((cmd (intern (car r)))) (when (and (boundp 'multiple-cursors-mode) multiple-cursors-mode cmd (not (memq cmd mc--default-cmds-to-run-once)) (not (memq cmd mc/cmds-to-run-once)) (or mc/always-run-for-all (memq cmd mc--default-cmds-to-run-for-all) (memq cmd mc/cmds-to-run-for-all) (mc/prompt-for-inclusion-in-whitelist cmd))) (mc/execute-command-for-all-fake-cursors cmd)))) (advice-add #'counsel-M-x-action :around #'adviced:counsel-M-x-action)

String inflection Emacs package
string-inflection (by Akira Ikeda) is a nifty package to cycle through string case styles: camel, snake, kebab… The package includes a handful of cycling functions for different languages (Ruby, Python and Java), but it's easy to mix and match to roll your own. For now, I'm binding C-M-j to string-inflection-cycle, which is an alias to string-inflection-ruby-style-cycle.
(use-package string-inflection :ensure t :bind (:map prog-mode-map ("C-M-j" . string-inflection-cycle)))

Dal Makhani (black lentils) recipe
Soak beans (overnight)
- 1 cup of rajmah (kidney beans).
- 2 cups of sabut urad (black lentils).
Place the beans in a bowl with plenty of water. The beans will soak it up so ensure there's enough.
Cooking the beans
- 3 liters of water.
- 1 cinamon stick.
- 1 tablespoon of turmeric.
- 2 bay leaves.
Drain the beans and combine new ingredients into a pot. Bring to a boil and simer for 1.5 hours. Check beans aren't firm (give 'em a try'). If so extend another 15-30 mins.
Prepare paste
- 1 4 cm piece of ginger.
- 1 large onion.
- 6 garlic cloves.
- 2 tomatoes.
Put through blender (with choppin pulse) or food processor until you get a paste.
Golden paste
- Paste.
- 3 tablespoons of butter.
- 1 tablespoon of cumin seeds.
- 1 tablespoon of coriander powder.
- 1 tablespoon of chilly powder (or less to make milder).
- 1 fresh red hot pepper (find one with medium heat level) chopped.
- 1 tablespoon of cumin powder.
- 1/4 cup of water.
- 3/4 tablespoon of salt.
Heat up the butter (medium heat) and brown the cumin seeds (maybe 30 seconds). Add the paste from previous step. Cook for about 4 minutes or until golden. Add the remaining ingredients in step (except water) and cook for another 30 seconds. Add the water and salt and mix to make more fluid and remove from heat.
Tying it all together
- 1 tablespoon of panchpuram (cumin, fenugreek, mistard, and fennel seeds).
- 300 ml of double cream.
Combine the cooked beans, golden paste, and seeds. Simmer for about 15 minutes. Add the cream and cook for about 2 minutes. You are effectively done.
Garnish (optional)
You can serve and optionally garnish with some chopped coriander. Recommended.
Serve with
Basmati rice, rotis, buttered buns, or even corn tortillas (unorthodox, but hey).
Modern Emacs lisp libraries
Quickly finding related built-in elisp functions (without prefixes) can sometimes take a little poking around.
Some modern and predictable built-in exceptions I now reach out to are:
- map.el for key/values, alists, hash-tables and arrays (built-in as of Emacs 25.1).
- seq.el for sequence manipulation functions (built-in as of Emacs 25.1).
- subr-x.el has a handful of string functions (built-in as of Emacs 24.4).
- let-alist.el wonderful syntax for alists, great for json (built-in as of Emacs 25.1).
If you don't mind reaching out to third-party libs (you likely have some of these already installed), here are some modern, predictable, and well-documented ones that always get me out of trouble:
- s.el string manipulation.
- f.el file/path handling.
- dash.el for lists.
- ht.el for hashtables.
- ts.el for date and time.
I'm happy with built-ins like map.el, seq.el, and let-alist.el. subr-x.el is also pretty nice, although not as full-featured as third-party s.el.
Am I missing out on other modern built-ins or third-party libraries?
UPDATE: Added a handful of newly discovered libraries plus suggestions by Daniel Martín (thanks!). Not tried any of these myself.
- rtree.el binary tree that stores ranges (Built-in).
- ov.el simple way to manipulate overlay.
- Toby Cubitt's libraries (heap, overlays, queue, avl-tree, trie, dict-tree, etc).
- shadchen.el pattern-matching.
- m-buffer.el buffers.
- esxml.el xml and html.
- a.el associative structures.
- asoc.el association list library.
- yk-color.el linear RGB color manipulation.

Emacs smartparens auto-indent
While I do most editing in Emacs, I use Xcode every now and then. I like Xcode's pair matching (of brackets) combined with its auto-indent.
While the wonderful smartparens gives Emacs pair-matching powers, it doesn't automatically indent between pairs (out of the box anyway).
Luckily, smartparens does provide sp-local-pair, which enables us to achieve a similar goal.
With a short snippet, we can autoindent between {}, [], and () when pressing return in-between.
(defun indent-between-pair (&rest _ignored) (newline) (indent-according-to-mode) (forward-line -1) (indent-according-to-mode)) (sp-local-pair 'prog-mode "{" nil :post-handlers '((indent-between-pair "RET"))) (sp-local-pair 'prog-mode "[" nil :post-handlers '((indent-between-pair "RET"))) (sp-local-pair 'prog-mode "(" nil :post-handlers '((indent-between-pair "RET")))

Fixing Honeywell CM927's dead screen
My Honeywell CM927 thermostat's screen had been getting progressively worse over the last year. As of late, the screen was of little use.
A random search yielded the Honeywell CM927 LCD screen fail - common? thread, with a promising comment by Phil:
"Strip the unit and remove the circuit board (just a few plastic clips, no screws). Remove the LCD assembly from the circuit board (more plastic clips and an eight pin push connection). Removed the LCD unit from the clear plastic housing (more plastic clips). Finally heat up the plastic ribbon where it is stuck to the circuit board (hair dryer will do trick) and then firmly press it onto the circuit board… probably worth doing this several times; in effect you are remating the ribbon to the circuit board by softening the adhesive. Put it all back together and it should be working again."
Phil's instructions were great. There's also a super handy video by El Tucan, also linked by Stevie.
Success \o/
Heating up the plastic ribbon and pressing it onto the circuit board did the trick for me. Took a few tries for all segments to appear, but the screen is looking great again.
Thank you Internet strangers! :)

Studying for Life in the UK test
Today, I passed the Life in the UK test. Wasn't quite sure how to study for it. During my commutes, I listened to the Life in the UK 2019 Test audio book.
A friend recommended lifeintheuktestweb.co.uk. Overall, I found their practice tests very useful. Taking a bunch tests helped me internalize the material.
Took some notes along the way (mostly data with years attached) and dumped it into an org table. This helped me form a mental timeline.
NOTE: These tables alone are not comprehensive enough to prepare for the exam. You'll need to know additional information without dates attached.

Wizard zines comics in Emacs eshell
Over at wizardzines.com, Julia Evans authors wonderful zines on topics like git, networking, linux, command-line utilities, and others. Some zines are paid. Some are free. No affiliation here, just a fan.
A little while ago, Julia tweeted about a utility she's building to view her original comics on similar topics. I instantly thought it'd be a fun tool to implement for Emacs eshell.
Since then, I subscribed to wizardzines.com/saturday-comics and received a few comics (awk, tar, and bash tricks). I saved them locally (using topic name and dropping file extensions).
ls -1 ~/Downloads/wizardzines-comics/
awk |
bash |
tar |
By no means battle-tested, but here's an elisp snippet defining the ecomic command. It displays inlined comics in the handy eshell.
(require 'eshell) (require 'iimage) (defvar wizardzines-comics-path "~/Downloads/wizardzines-comics") (defun eshell/ecomic (&rest args) "Display command comic in ARGS. Note: ensure comic images live in `wizardzines-comics-path', named with command name and no extension." (eshell-eval-using-options "ecomic" args '((?h "help" nil nil "show this usage screen") :external "ecomic" :show-usage :usage "COMMAND Show COMMAND comic from Julia Evans' https://wizardzines.com/saturday-comics") (let* ((command (nth 0 (eshell-stringify-list (eshell-flatten-list args)))) (image-fpath (concat (file-name-as-directory (expand-file-name wizardzines-comics-path)) command))) (unless (file-exists-p image-fpath) (error "comic: \"%s\" not found :-(" command)) (eshell-buffered-print "\n") (add-text-properties 0 (length image-fpath) `(display ,(create-image image-fpath) modification-hooks (iimage-modification-hook)) image-fpath) (eshell-buffered-print image-fpath) (eshell-flush))))

Emacs counsel default search switches
Following up from Enhanced Emacs searching with counsel switches, rather than remembering silver searcher and ripgrep switches, we can use counsel's ivy-initial-inputs-alist to set these up as default visible switches.
(push '(counsel-ag . "--file-search-regex '' -- ") ivy-initial-inputs-alist) (push '(counsel-rg . "--glob '**' -- ") ivy-initial-inputs-alist)
The default switches stay out of the way in typical searches, but can be easily modified to include (or exclude) results matching specific file names.

Enhanced Emacs searching with counsel switches
The counsel family of Emacs search commands are great for searching the filesystem. More specifically, counsel-rg, counsel-ag, and counsel-pt, which use the popular ripgrep, silver searcher, and platinum searcher utilities.
counsel-rg is my default searcher. It returns results quickly, with live updates as I tweak the search query.
Up until recently, my queries typically matched text in files only. This works great, but every so often I wished I could amend the query to include (or exclude) results matching specific file names. Turns out, you can prepend the search query with additional switches using the "–" separator.
The switches are usually utility-specific, but if we wanted to keep results from file names matching a glob, we can prepend the ripgrep query with something like "–glob Make* –" or the shorter version "-g Make* –".
rg: -g Make* – install
Emacs org block company completion
UPDATE: This is now available on melpa.
Back in 2015, I bound the "<" key to a hydra for quickly inserting org blocks. The idea came from Oleg's post on org-mode block templates in Hydra. The suggested binding settled in my muscle memory without much effort.
Fast forward to Febrary 2019. I replaced the hydra with org-insert-structure-template when org-try-structure-completion was removed from org mode. No biggie, as I kept the same binding to "<" and hardly noticed the change.
Since my primary use-case for easy templates is inserting source blocks, I was keen to expedite choosing the source language as well as inserting the source block itself.
Writing a small company mode completion backend fits my primary use-case pretty well.
The company backend looks as follow (Warning: Snippet needs Org v9.2).
Note: This code is not up to date. Install via melpa or see its repository.
(require 'map) (require 'org) (require 'seq) (defvar company-org-block-bol-p t "If t, detect completion when at begining of line, otherwise detect completion anywhere.") (defvar company-org--regexp "<\\([^ ]*\\)") (defun company-org-block (command &optional arg &rest ignored) "Complete org babel languages into source blocks." (interactive (list 'interactive)) (cl-case command (interactive (company-begin-backend 'company-org-block)) (prefix (when (derived-mode-p 'org-mode) (company-org-block--grab-symbol-cons))) (candidates (company-org-block--candidates arg)) (post-completion (company-org-block--expand arg)))) (defun company-org-block--candidates (prefix) "Return a list of org babel languages matching PREFIX." (seq-filter (lambda (language) (string-prefix-p prefix language)) ;; Flatten `org-babel-load-languages' and ;; `org-structure-template-alist', join, and sort. (seq-sort #'string-lessp (append (mapcar #'prin1-to-string (map-keys org-babel-load-languages)) (map-values org-structure-template-alist))))) (defun company-org-block--template-p (template) (seq-contains (map-values org-structure-template-alist) template)) (defun company-org-block--expand (insertion) "Replace INSERTION with actual source block." (delete-region (point) (- (point) (1+ ;; Include "<" in length. (length insertion)))) (if (company-org-block--template-p insertion) (company-org-block--wrap-point insertion ;; May be multiple words. ;; Take the first one. (nth 0 (split-string insertion))) (company-org-block--wrap-point (format "src %s" insertion) "src"))) (defun company-org-block--wrap-point (begin end) "Wrap point with block using BEGIN and END. For example: #+begin_BEGIN | #+end_END" (insert (format "#+begin_%s\n" begin)) (insert (make-string org-edit-src-content-indentation ?\s)) ;; Saving excursion restores point to location inside code block. (save-excursion (insert (format "\n#+end_%s" end)))) (defun company-org-block--grab-symbol-cons () "Return cons with symbol and t whenever prefix of < is found. For example: \"<e\" -> (\"e\" . t)" (when (looking-back (if company-org-block-bol-p (concat "^" company-org--regexp) company-org--regexp) (line-beginning-position)) (cons (match-string-no-properties 1) t)))
To use, add the backend enable company-mode in org-mode:
(add-to-list 'company-backends 'company-org-block) (company-mode +1)
Updates
- Removed language-specific header logic (use org-babel-default-header-args instead).
- Also completes non-source block templates from org-structure-template-alist.
- Source in my dot files.
- Removed unnecessary binding. Just add company backend as usual.
- Thanks to Takaaki Ishikawa for suggesting `org-edit-src-content-indentation'.
- Thanks to Thomas Kobber for highlighting incompatibility with older org versions.

A more reusable Emacs shell-command history
Cameron Desautel has a great post on Working Faster in Emacs by Reading the "Future", highlighting M-n's usefulness for inserting minibuffer default values.
Invoking M-n in shell-command's prompt is handy for quickly getting the current buffer's file name. This works great for one-off shell commands like "chmod +x script.sh" or "tidy -xml -i -m data.xml". Unfortunately, these commands aren't easily reusable from shell-command's minibuffer history, since it'll keep hardcoded file names.
There's likely existing built-in functionality or a more elaborate package for this, but advising read-shell-command enables us to write more reusable commands like "chmod +x $f" or "tidy -xml -i -m $f". We merely replace $f with (buffer-file-name), and let everything else continue as usual.
(defun ar/adviced-read-shell-command (orig-fun &rest r) "Advice around `read-shell-command' to replace $f with buffer file name." (let ((command (apply orig-fun r))) (if (string-match-p "\\$f" command) (replace-regexp-in-string "\\$f" (or (buffer-file-name) (user-error "No file file visited to replace $f")) command) command))) (advice-add 'read-shell-command :around 'ar/adviced-read-shell-command)
It's worth mentioning that searching minibuffer history is pretty simple when leveraging counsel to fuzzy search (via counsel-minibuffer-history, bound to C-r by default).
On a final note, searching minibuffer history for cache hits is way more useful with richer history content. Be sure to save minibuffer history across Emacs sessions and increase shell-command-history using the built-in savehist-mode.
(use-package savehist :custom (savehist-file "~/.emacs.d/savehist") (savehist-save-minibuffer-history t) (history-length 10000) (savehist-additional-variables '(shell-command-history)) :config (savehist-mode +1))

Emacs swiper and multiple cursors
Emacs swiper is awesome. I bound swiper-isearch to C-s. Also a big fan of multiple cursors. I use it regularly (it's fun).
I had totally missed Ole's post back in 2015: A simple multiple-cursors extension to swiper. Turns out, swiper has multiple cursors support out of the box (bound to C-7 by default). Yay!
UPDATE: Thanks to irreal's post, please remember to add swiper-mc to mc/cmds-to-run-once list (or things won't work as expected). This typically happens interactively when you invoke C-7 the first time around. Make sure you answer "n" when you see a prompt like:
If you happen to choose "y" by mistake, take a look at ~/.emacs.d/.mc-lists.el to correct it. Remove swiper-mc from mc/cmds-to-run-for-all and add it to mc/cmds-to-run-once. Invoke m-x eval-buffer to reset the values and you're good to go.

Spam blacklisting with Emacs org babel
Some email provider accept regular expressions to blacklist additional spam. My blacklist is long and tedious to update, but hey… Emacs org babel can simplify things here.
It's way easier to maintain a blacklist (with no regex) using an org table.
Blacklist
#+name: spam-entries | .spammy | | dodgyfella@hotmail.com | | henryzeespammer.com | | yumspam.com |
and subsequently use org babel (elisp snippet) to generate the regex.
Regex gen
#+begin_src emacs-lisp :var rows=spam-entries (require 'dash) (require 's) (concat "^" (s-join "|" (mapcar (lambda (entry) (setq entry (regexp-quote (s-trim entry))) (assert (s-present? entry)) (cond ;; Blacklist email address: joe@spammer.spammy ((s-contains-p "@" entry) (format "(%s)" entry)) ;; Blacklist top-level domain: .spammy ((s-starts-with-p "\\." entry) (format "([^.]*%s)" entry)) ;; Blacklist domain: @spammer.spammy (t (format "(.*@%s)" entry)))) (-sort 'string< (-map (lambda (row) (nth 0 row)) rows)))) "$") #+end_src #+RESULTS: : ^([^.]*\.spammy)|(dodgyfella@hotmail\.com)|(.*@henryzeespammer\.com)|(.*@yumspam\.com)$
UPDATE: Tweaked elisp and regex (but not animation) also found John Bokma's post: Blacklisting domains with Postfix.
Rewriting dates with Emacs multiple cursors
Needed to rewrite the date format in a couple of csv columns. Emacs multiple cursors helps here, but needed a function to parse and reformat the dates themselves.
I can likely reformat dates using the built-in parse-time-string and format-time-string functions, but hey why not give the ts.el library a try…
(defun ar/region-to-timestamp () "Convert date like \"29 Apr 2019\" to \"2019-04-29\"." (interactive) (let ((date (ts-parse (buffer-substring (region-beginning) (region-end))))) (delete-region (region-beginning) (region-end)) (insert (ts-format "%Y-%m-%d" date))))
Bound the new function to a temporary keybinding, so I can invoke from multiple cursors:
(bind-key "M-q" #'ar/region-to-timestamp)
and voilà!
Show/hide Emacs dired details in style
Emacs dired is a powerful directory browser/editor. By default, it shows lots of handy file and directory details.
I typically prefer hiding file and directory details until I need them. The built-in dired-hide-details-mode makes this easy with the "(" key toggle. Coupled with Steve Purcell's diredfl (for coloring), it strikes a great user experience.
With a short snippet, you can also show/hide dired details in style:
(use-package dired :hook (dired-mode . dired-hide-details-mode) :config ;; Colourful columns. (use-package diredfl :ensure t :config (diredfl-global-mode 1)))
UPDATE: Thanks to Daniel Martín, who pointed me to dired-git-info. This package adds git logs to dired file and directory details.
Binding dired-git-info-mode to ")" is a nice complement to dired-hide-details-mode's "(" binding.
(use-package dired-git-info :ensure t :bind (:map dired-mode-map (")" . dired-git-info-mode)))

Batch file renaming with counsel, find-dired, and wdired
The first time I saw wdired in action, it blew my mind. wdired makes dired (directory editor) buffers writeable, so you can edit them like any other Emacs buffer. You can subsequently use all your favorite file-editing tricks to rename files (amongst other things). You can see it in action at the end of Emacs Rocks episode 16.
When combining find-dired with wdired, one can easily find matching files and quickly batch rename them using something like multiple cursors or keyboard macros. I've been a fan of the find-dired -> dired-toggle-read-only -> mc/mark-all-like-this workflow for quite some time, but I always wished I could adjust find-dired queries a little quicker by getting immediate feedback.
Completion frontends like ivy and helm are perfect for getting this kind of immediate feedback. Peeking into ivy's counsel source, I borrowed some ideas to glue counsel-style narrowing on a find command, which I can easily translate to a writeable dired buffer for all that joyful-mutiple-cursor-editing experience.
The code for ar/counsel-find is a little rough but can be found at here.

Mark region, indent, restore location
When I'm not using an automatic code formatter (ie. clang-format, gofmt, etc.), I often find myself using Emacs region marking commands like mark-defun, er/expand-region, and mark-whole-buffer prior to pressing <tab>, which is bound to indent-for-tab-command.
This is all working as expected: the selection gets indented and the point is left in the current location.
Say we have the following snippet we'd like to indent.
Mark region with C-M-h (mark-defun)
Indent with <tab> (indent-for-tab-command)
We're done. The selected function is now indented as expected.
But… I always wished the point returned to the location prior to initiating the region-marking command, in this case mark-defun.
In short, I wish the point had ended in the following location.
I'm not aware of an existing package that helps with this, so here's a tiny minor mode (divert-mode) to help with restoring point location after indenting a region. The diverted-events variable can be used to track specific region selecting commands and associate breadcrumb functions to replace the point location as needed.
;;; diverted.el --- Identify temporary diversions and automatically ;;; move point back to original location. ;;; Commentary: ;; Automatically come back to a original location prior to diversion. ;;; Code: (require 'cl) (require 'seq) (defstruct diverted-event from ;; Initial function (eg.

(defun diverted--resolve (symbol) "Resolve SYMBOL to event."

Compound interest calculations
Saving Tony Bedford's python snippets for calculating compound interest. Really just an excuse to fire up Emacs and play with org babel.
t = 20 # years r = 0.07 # rate pv = 200000.00 # present value fv = pv * (1+r)**t # future value print("Pension of %.2f at %d%% will be worth %.2f in %d years" % (pv, 100 * r, fv, t))
Pension of 200000.00 at 7% will be worth 773936.89 in 20 years
t = 20 # years r = 0.07 # rate pv = 200000.00 # present value n = 1 fv = pv * (1 + r/n)**(n*t) # future value print ("First formula calculates final value to: %.2f" % fv) fv = pv * (1 + r/n)**(n*1) # year 1 only print("Year %d: %.2f" % (1, fv)) for i in range (2, t+1): fv = fv * (1 + r/n)**(n*1) # Calculate one year at a time print("Year %d: %.2f" % (i, fv))

Building mu/mu4e on macOS
I've now built Emacs's mu/mu4e releases a handful of times on macOS. These are the steps, so I don't forget.
1.4
Updated steps for building mu/mu4e 1.4:
brew install gmime export CPPFLAGS="-I$(brew --prefix)/Cellar/gmime/3.2.3/include -I$(brew --prefix)/include" export LDFLAGS=-L$(brew --prefix)/Cellar/gmime/3.2.3/lib export PKG_CONFIG_PATH=$(brew --prefix)/Cellar/gmime/3.2.3/lib/pkgconfig:$(brew --prefix)/opt/libffi/lib/pkgconfig export EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs ./configure --prefix=$(~/local) make install
1.2
Recently built Emacs's mu/mu4e 1.2.0 from source on macOS. Steps:
brew install gmime export CPPFLAGS=-I$(brew --prefix)/Cellar/gmime/3.2.3/include export LDFLAGS=-L$(brew --prefix)/Cellar/gmime/3.2.3/lib export PKG_CONFIG_PATH=$(brew --prefix)/Cellar/gmime/3.2.3/lib/pkgconfig:$(brew --prefix)/opt/libffi/lib/pkgconfig ./configure --prefix=$(~/local) --disable-dependency-tracking make install
UPDATE(2019-04-16): Another approach at Irreal's Mu/mu4e 1.2 Available.

Inserting numbers with Emacs multiple cursors
TIL that multiple cursor's mc/insert-numbers enables you to quickly enter increasing numbers for each cursor. I have mc/insert-numbers bound to # in region-bindings-mode-map. By default, sequence starts at 0, but invoking mc/insert-numbers with prefix enables you to quickly change that.

No Emacs frame refocus on macOS
This one's been bugging me for a while. On macOS, Emacs automatically focuses (raises) other frames when one is closed.
This has the unfortunate side-effect that I could be moved from one macOS desktop/space to another when closing an Emacs frame.
Finally managed do something about it. Since I install Emacs on macOS via homebrew, a small patch on emacs-plus recipe small patch on emacs-plus recipe did the job.
UPDATE: Pull request merged in d12frosted/emacs-plus.
The patch patch has been merged into d12frosted/homebrew-emacs-plus. To use:
brew tap d12frosted/emacs-plus brew install emacs-plus --without-spacemacs-icon --with-no-frame-refocus
Balance restored.

Copy from desktop to mobile via QR code
Marcin Borkowski has a nice tip to quickly copy text or URLs between desktop and mobile using QR codes.
Wrote a little elisp to do a similar thing using the clipboard via Emacs:
(defun ar/misc-clipboard-to-qr () "Convert text in clipboard to qrcode and display within Emacs." (interactive) (let ((temp-file (concat (temporary-file-directory) "qr-code"))) (if (eq 0 (shell-command (format "qrencode -s10 -o %s %s" temp-file (shell-quote-argument (current-kill 0))) "*qrencode*")) (switch-to-buffer (find-file-noselect temp-file t)) (error "Error: Could not create qrcode, check *qrencode* buffer"))))
ps. Encoding your WiFi access point password into a QR code shows how to encode WiFi access point passwords:
qrencode -o wifi.png "WIFI:T:WPA;S:<SSID>;P:<PASSWORD>;;"
More comprehensively:
SSID=SSID_GOES_HERE pwgen -s 63 > 00wifi.txt qrencode -o 00wifi.png "WIFI:T:WPA;S:${SSID};P:$(cat 00wifi.txt);;"
Parsing dates in Go
Ensure the reference time ("Mon Jan 2 15:04:05 -0700 MST 2006") is used in layout string.
For example:
package main import ( "fmt" "time" ) func main() { goodLayout := "January 2 2006" if t, err := time.Parse(goodLayout, "March 10 2019"); err != nil { fmt.Printf("%s\n", err) } else { fmt.Printf("%v\n", t) } badLayout := "January 2 2009" if t, err := time.Parse(badLayout, "March 10 2019"); err != nil { fmt.Printf("%s\n", err) } else { fmt.Printf("%v\n", t) } }
2019-03-10 00:00:00 +0000 UTC parsing time "March 10 2019" as "January 2 2009": cannot parse "19" as "009"

Swapping Emacs ivy collections/sources
Ivy is great. I've been meaning to figure out a way to swap sources while running ivy. This would enable me to cycle through different sources using the existing search parameters.
At first look, 'ivy-set-sources seemed like the right choice, but it's used during setup to agregate sources. Subsequent 'ivy-set-sources calls are ignored during an 'ivy-read session.
There's an ivy feature request over at github with a similar goal in mind. Although the feature is not yet supported, there's a handy suggestion to use 'ivy-quit-and-run to quit the current command and run a different one.
With 'ivy-quit-and-run in mind, we can write our 'ar/ivy-read function to take a list of sources and add a little logic to cycle through them using a keybiding, in my case <left> and <right>.
;;; -*- lexical-binding: t; -*- (require 'cl) (cl-defstruct ar/ivy-source prompt collection action) (cl-defun ar/ivy-read (sources &key index initial-input) (let ((kmap (make-sparse-keymap)) (source)) (cl-assert (> (length sources) 0)) (when (null index) (setq index 0)) (setq source (nth index sources)) (define-key kmap (kbd "<right>") (lambda () (interactive) (ivy-quit-and-run (ar/ivy-read sources :index (if (>= (1+ index) (length sources)) 0 (1+ index)) :initial-input ivy-text)))) (define-key kmap (kbd "<left>") (lambda () (interactive) (ivy-quit-and-run (ar/ivy-read sources :index (if (< (1- index) 0) (1- (length sources)) (1- index)) :initial-input ivy-text)))) (ivy-read (ar/ivy-source-prompt source) (ar/ivy-source-collection source) :action (ar/ivy-source-action source) :initial-input initial-input :keymap kmap))) (defun ar/ivy-food-menu () (interactive) (ar/ivy-read (list (make-ar/ivy-source :prompt "Pizza: " :action (lambda (selection) (message "Selected pizza: %s" selection)) :collection (lambda (str pred v) (list "Bianca Neve - Mozzarella, Ricotta, Sausage, Extra Virgin Olive Oil, Basil" "Boscaiola - Mozzarella, Tomato Sauce, Sausage, Mushrooms, Extra Virgin Olive Oil, Basil" "Calzone - Ricotta, Ham, Mushrooms, Artichokes.

Trying out Emacs pdf tools
Late to the party, giving pdf-tools a try.

ps. (pdf-tools-install) may not find libffi on macOS. Try:
(setenv "PKG_CONFIG_PATH" (f-join (file-name-as-directory (nth 0 (split-string (shell-command-to-string "brew --prefix")))) "Cellar" "libffi" "3.2.1" "lib" "pkgconfig"))

Using OCR to create searchable pdfs from images
Used my phone to take a handful of photos of an article from a magazine. Wanted to convert the images to a searchable pdf on macOS.
This was straightforward, having already installed tesseract.
for i in IMG_3*.jpg; do echo $i; tesseract $i $(basename $i .tif) pdf; done
Should now have a handful of OCR'd pdfs:
ls *.jpg.pdf
IMG_3104.jpg.pdf IMG_3105.jpg.pdf IMG_3106.jpg.pdf IMG_3107.jpg.pdf
Finally, join all pdfs into one. Turns out macOS has a handy python script already installed. We can use it as:
/usr/bin/python "/System/Library/Automator/Combine PDF Pages.action/Contents/Resources/join.py" -o joined.pdf IMG_*pdf
ps. pdfgrep is great for searching pdfs.

Emailing pdfs to kindle from mu4e
Wanted to send a pdf to my kindle for some holiday reading. You can easily do this by emailing the pdf to your kindle-bound email address.
Now, I typically attach files when composing mu4e emails by using mml-attach-file, which attaches the file using <#part>…<#/part>. However, the Amazon service did not find the attached pdf, so no pdf was added to my Kindle.
Fortunately, I found a handy Reddit thread, leding me to a working solution. Wrapping the part using <#multipart type=mixed>…<#/multipart> did the job, using mml-insert-multipart, followed by mml-attach-file.
Resulting attachment should look something like:
<#multipart type=mixed> <#part type="application/pdf" filename="/path/to/file.pdf" disposition=attachment> <#/part> <#/multipart>
I should add a convenience elisp function for this, but that's for another time…

DWIM ivy quit
"Do-what-I-mean" (DWIM) functions enable us to introduce new Emacs powers to existing workflows without incurring the typical cost of remembering multiple related functions or introducing yet another key binding. DWIM functions invoke other functions, based on current context.
I wanted a small tweak in Ivy's `minibuffer-keyboard-quit' invocation, commonly invoked via C-g key binding:
- If we have text selected in minibuffer, deselect it.
- If we have any text in minibuffer, clear it.
- If no text in minibuffer, quit.
Added `ar/ivy-keyboard-quit-dwim' for this purpose. Binding it to C-g in ivy-minibuffer-map:
(use-package ivy :ensure t :bind (:map ivy-minibuffer-map ("C-g" . ar/ivy-keyboard-quit-dwim)) :config (defun ar/ivy-keyboard-quit-dwim () "If region active, deactivate. If there's content, clear the minibuffer. Otherwise quit." (interactive) (cond ((and delete-selection-mode (region-active-p)) (setq deactivate-mark t)) ((> (length ivy-text) 0) (delete-minibuffer-contents)) (t (minibuffer-keyboard-quit)))))
Diffing directories content size
Needed to diff two directories, but only interested in file size changes. diff, find, sort, and stat seem to do the job:
diff <(find dir1 -type f -exec stat -f '%N %z' '{}' \; | sort) <(find dir2 -type f -exec stat -f '%N %z' '{}' \; | sort)
1,3c1,2 < dir1/one.txt 14 < dir1/subdir/file.txt 5 < dir1/three.txt 7 --- > dir2/one.txt 19 > dir2/two.txt 0
Note: Using diff, find, sort, and stat on macOS.

(interactive) (let* ((dir1-path (read-directory-name "Dir 1: ")) (dir2-path (read-directory-name "Dir 2: ")) (buf1 (get-buffer-create (format "*Dir 1 (%s)*" (f-base dir1-path)))) (buf2 (get-buffer-create (format "*Dir 2 (%s)*" (f-base dir2-path))))) (with-current-buffer buf1 (erase-buffer)) (with-current-buffer buf2 (erase-buffer)) (shell-command (format "cd %s; find . -type d | sort | du -h" dir1-path) buf1) (shell-command (format "cd %s; find . -type d | sort | du -h" dir2-path) buf2) (ediff-buffers buf1 buf2)))
Swift nil-coalescing operator
Paul Hudson, over at Hacking with Swift, has written The Complete Guide to Optionals in Swift. One of the many highlights is the nil-coalescing operator. If you're a fan of the C-like syntax in ternary operations, you'd enjoy chaining with Swift's nil-coalescing operator:
let players = [ "goose": "run!" ] let move = players["duck1"] ?? players["duck2"] ?? players["duck3"] ?? players["goose"] print("\(String(describing: move))")
Optional("run!")
ps. Swift snippet run on Emacs org babel's ob-swift. See Multiline Swift strings for details.
Ocado vs Asda (org table)
Someone handed me an Ocado shopping voucher for 30% off. Sounded promising, even for a one-off.
With my Money or Your Life hat on, I took a closer look for potential savings. Results were disappointing, when compared to alternatives like Asda.
Here's a table comparing Ocado (30% off) and Asda (no discount):
Ocado | Asda | |
---|---|---|
Coconut Merchant Organic Raw Extra Virgin Coconut Oil 500ml | 6.74 | |
KTC 100% pure coconut oil | 2.00 | |
Waitrose Love Life Popcorn Maize 510g | 1.50 | |
Cypressa Popping Corn 2x500g = 1000g | 1.50 | |
Whitworths Ground Almonds | 2.00 | |
Whitworths Ground Almonds | 1.60 | |
Total | £ 5.10 | |
-30% | £ 7.17 |
On the upside, Ocado has plenty of items I cannot find at Asda. May be a good opportunity to get these items at a discount.
Emacs org tables
Small tables are the perfect use-case for Emacs org-mode tables. Been a while since I used one, so great timing for a little refresh.
Here's the org source for the table above (prior to exporting to HTML):
|-------------------------------------------------------------+--------+--------| | | Ocado | Asda | |-------------------------------------------------------------+--------+--------| | [[https://www.ocado.com/webshop/product/Coconut-Merchant-Organic-Raw-Extra-Virgin-Coconut-Oil/372144011][Coconut Merchant Organic Raw Extra Virgin Coconut Oil 500ml]] | 6.74 | | | [[https://groceries.asda.com/product/oils/ktc-coconut-hair-oil/910000033621][KTC 100% pure coconut oil]] | | 2.00 | | [[https://www.ocado.com/webshop/product/Waitrose-Love-Life-Popcorn-Maize/25130011][Waitrose Love Life Popcorn Maize 510g]] | 1.50 | | | [[https://groceries.asda.com/promotion/2-for-pound-1.50/ls89129][Cypressa Popping Corn 2x500g = 1000g]] | | 1.50 | | [[https://www.ocado.com/webshop/product/Whitworths-Ground-Almonds/275684011][Whitworths Ground Almonds]] | 2.00 | | | [[https://groceries.asda.com/product/baking-nuts-seeds-fruit/whitworths-ground-almonds/910000797981][Whitworths Ground Almonds]] | | 1.60 | |-------------------------------------------------------------+--------+--------| | Total | | £ 5.10 | |-------------------------------------------------------------+--------+--------| | -30% | £ 7.17 | | |-------------------------------------------------------------+--------+--------| #+TBLFM: @8$3=vsum(@2$3..@7$3);£ %.2f::@9$2=vsum(@2$2..@7$2) * 0.7;£ %.2f
Execute org blocks as root
Been saving admin code snippets in my own org source blocks, some requiring root access. Handy for keeping tiny self-documented scripts to easily bootstrap other machines. TIL org source block's :dir argument can be used to run block as root by using tramp syntax: :dir /sudo::
As user: #+BEGIN_SRC sh whoami #+END_SRC #+RESULTS: : user As root: #+BEGIN_SRC sh :dir /sudo:: whoami #+END_SRC #+RESULTS: : root
Inline Swift computed properties
Via objc.io and Max Howell's retweet, TIL about Swift's inline computed properties. Another one to try on Org Babel.
func greetWorld() { var message = "hello" var betterMessage: String { return "\(message) world" } print(betterMessage) } greetWorld()
hello world
Multiline Swift strings
Paul Hudson's tweet introduced me to Swift's multiline string indentation control using closing quotes. Neat!
Being an org-mode fan, I thought I'd give Swift multiline strings a try using Org Babel's ob-swift. I get to verify it and document at the same time. Win.
Swift org mode source blocks (ie. BEGIN_SRC/END_SRC) can be added as follows:
#+BEGIN_SRC swift :exports both print(""" Hello World """) print(""" Hello World """) #+END_SRC #+RESULTS: : Hello World : Hello World
By pressing C-c C-c anywhere in the code block, the snippet is executed and its output captured in the RESULT block. Super handy for quickly trying out snippets and keeping as future reference.
As a bonus, the above blocks can be exported to HTML (amongst other formats). With some styling, it looks as follows:
print(""" Hello World """) print(""" Hello World """)
Hello World Hello World
Quickly swapping elfeed filters
I seem to be more efficient in getting through rss feeds by individually browsing through related content. That is, I can get through all Emacs entries a lot faster if I look at Emacs content exclusively, instead of mixing with say BBC news. Elfeed filters are great for filtering related content.
I wanted a way to easily switch through my typical categories of related content by quickly changing elfeed filters using a completion framework.
Emacs's completing-read plays nicely with your favorite completing framework (mine is ivy). With a couple of functions, we can get Emacs to ask us for the filtering category using human-readable options and quickly presenting related content. Binding the new functionality to <tab> is working well for me.
(use-package elfeed :ensure t :commands elfeed :bind (:map elfeed-search-mode-map ("<tab>" . ar/elfeed-completing-filter)) :config (defun ar/elfeed-filter-results-count (search-filter) "Count results for SEARCH-FILTER." (let* ((filter (elfeed-search-parse-filter search-filter)) (head (list nil)) (tail head) (count 0)) (let ((lexical-binding t) (func (byte-compile (elfeed-search-compile-filter filter)))) (with-elfeed-db-visit (entry feed) (when (funcall func entry feed count) (setf (cdr tail) (list entry) tail (cdr tail) count (1+ count))))) count)) (defun ar/elfeed-completing-filter () "Completing filter." (interactive) (let ((categories (-filter (lambda (item) (> (ar/elfeed-filter-results-count (cdr item)) 0)) '(("All" . "@6-months-ago +unread") ("BBC" . "@6-months-ago +unread +bbc") ("Dev" . "@6-months-ago +unread +dev") ("Emacs" . "@6-months-ago +unread +emacs") ("Health" . "@6-months-ago +unread +health") ("Hacker News" . "@6-months-ago +unread +hackernews") ("iOS" . "@6-months-ago +unread +ios") ("Money" . "@6-months-ago +unread +money"))))) (if (> (length categories) 0) (progn (ar/elfeed-view-filtered (cdr (assoc (completing-read "Categories: " categories) categories))) (goto-char (window-start))) (message "All caught up \\o/")))))
We don't actually need two functions, but ar/elfeed-filter-results-count enables us to list only those feeds that actually have new content. The list will shrink as we get through our content. When no content is left, we get a little celebratory message.
Converting docx to pdf on macOS
Wanted to convert a docx document to pdf on macOS. Pandoc to the rescue, but first needed pdflatex installed:
pandoc -t latex some.docx -o some.pdf
pdflatex not found. Please select a different --pdf-engine or install pdflatex
Installed pdflatex on macOS with:
brew install mactex
Can also use HTML5. Install wkhtmltopdf with:
brew install Caskroom/cask/wkhtmltopdf
Convert with:
pandoc -t html5 some.docx -o some.pdf
Faster elfeed browsing with paging
Following up from faster junk mail deletion with mu4e, elfeed is another candidate for enabling actions on pages. In this case, marking rss entries as read, page by Page.
If on use-package, the function can defined and bound to the "v" key using:
(use-package elfeed :ensure t :bind (:map elfeed-search-mode-map ("v" . ar/elfeed-mark-visible-as-read)) :config (defun ar/elfeed-mark-visible-as-read () (interactive) (require 'window-end-visible) (set-mark (window-start)) (goto-char (window-end-visible)) (activate-mark) (elfeed-search-untag-all-unread) (elfeed-search-update--force) (deactivate-mark) (goto-char (window-start))))
Faster junk mail deletion with mu4e
It's been roughly 5 months since my mu4e email migration. Happy with my choice. Mu4e is awesome.
I now have 4 email accounts managed by mu4e, and unfortunately receiving lots of junk mail.
I regularly peek at junk folders for false positives and delete junk email permanently. I've been wanting a quick way to glance at junk mail and easily delete page by page.
Deleting emails page by page is not supported in mu4e by default. Fortunately, this is Emacs and we can change that™.
There's a handy package by Roland Walker called window-end-visible. We can use it to select mu4e emails by page and subsequently glue it all together to enable deleting emails by page.
(require 'mu4e) (require 'window-end-visible) (defun ar/mu4e-delete-page () (interactive) (set-mark (window-start)) (goto-char (window-end-visible)) (activate-mark) (mu4e-headers-mark-for-trash) (mu4e-mark-execute-all t) (deactivate-mark) (goto-char (window-start)))
I'm a use-package fan, so I use it to bind the "v" key to delete visible emails (by page).
(use-package mu4e :bind (:map mu4e-headers-mode-map ("v" . ar/mu4e-delete-page))
Working with vultr's ipv6-only instances
Having recently read Your Money or Your Life, I've been cutting down on personal expenses wherever possible. Specially recurring expenses which include monthly charges from VPS hosting. Let's reduce those charges…
My VPS needs are fairly small (mostly hobby and tinkering). Vultr† has a plan for $2.50/month (not seen anything cheaper). The caveat for the price, you get ipv6 access only (ie. 0000:1111:2222:3333:4444:5555:6666:7777:8888).
So far so good, but my ISP doesn't yet support ipv6:
$ ping6 0000:1111:2222:3333:4444:5555:6666:7777:8888 $ ping6: UDP connect: No route to host
Fortunately, we can still work with ipv6 by using a tunnel (TIL about Hurricane Electric's tunnel broker). After signing up and creating a tunnel, they conveniently show you "Example Configurations" from the "Tunnel Details" menu. In my case, macOS:
ifconfig gif0 create ifconfig gif0 tunnel <ipv4 client broker IP or DCHP internal IP> <ipv4 server IP> ifconfig gif0 inet6 <ipv6 client broker IP> <ipv6 server IP> prefixlen 128 route -n add -inet6 default <ipv6 server IP>
Note: If behind router, use the DHCP internal IP.
After configuring with ifconfig, all is good. Yay!
$ ping6 0000:1111:2222:3333:4444:5555:6666:7777:8888 PING6(56=40+8+8 bytes) 2001:111:22:aaa::2 --> 0000:1111:2222:3333:4444:5555:6666:7777:8888 16 bytes from 0000:1111:2222:3333:4444:5555:6666:7777:8888, icmp_seq=0 hlim=52 time=270.019 ms 16 bytes from 0000:1111:2222:3333:4444:5555:6666:7777:8888, icmp_seq=1 hlim=52 time=290.834 ms 16 bytes from 0000:1111:2222:3333:4444:5555:6666:7777:8888, icmp_seq=2 hlim=52 time=311.960 ms 16 bytes from 0000:1111:2222:3333:4444:5555:6666:7777:8888, icmp_seq=3 hlim=52 time=330.902 ms
I'm an ipv6 noob. I mostly need ssh access. My typical usages need small tweaks.
For ssh:
ssh -6 username@0000:1111:2222:3333:4444:5555:6666:7777:8888
For scp:
scp -6 file.txt username@\[0000:1111:2222:3333:4444:5555:6666:7777:8888\]:/remote/dir/

M-r history search in git-commit-mode
I've grown accustomed to M-r bindings to search Emacs history. Been wanting similar functionality to search commit message history. Turns out log-edit-comment-ring has some of my local commit message history. Feeding it to completing-read gives me an easily searchable history when using a completing framework like ivy or helm:
(defun ar/git-commit-search-message-history () "Search and insert commit message from history." (interactive) (insert (completing-read "History: " ;; Remove unnecessary newlines from beginning and end. (mapcar (lambda (text) (string-trim text)) (ring-elements log-edit-comment-ring)))))
Now we bind it to M-r and we're good to go:
(bind-key "M-r" #'ar/git-commit-search-message-history git-commit-mode-map)
May also want to persist log-edit-comment-ring across Emacs sessions by adding log-edit-comment-ring to savehist variables. Also ensure savehist-mode is enabled:
(add-to-list 'savehist-additional-variables log-edit-comment-ring) (savehist-mode +1)

Marking 20k emails as read
Mbsync and mu4e are great for syncing and handling IMAP email. I've now migrated 4 email addresses, including an old Yahoo account.
I wanted to mark all my Yahoo unread emails as read. Yahoo's webmail enables marking 500 emails at a time, making the process a little tedious.
Mu-discuss has a handy thread, highlighting that moving/renaming synced messages (in your local file system) would do the job. This worked well for me.
Let's do just that…
WARNING: Copy a small sample of your mails to a separate directory and run some trials until you feel comfortable.
Find your mail directory.
cd path/to/mail
Peek at the messages you'd like to mark unread:
ls -1 new/
1529958027.57518_11.mbp,U=8415:2, 1531346210.38822_3.mbp,U=8741:2, 1532464801.21057_1.mbp,U=9028:2, 1532464801.21057_2.mbp,U=9029:2,
Rename message files by appending "S" to their filename and moving from new/ to cur/ directory.
for FILE in new/*; do mv "${FILE}" cur/$(basename "${FILE}")S; done;
We can verify the move.
ls -1 cur/
1529958027.57518_11.mbp,U=8415:2,S 1531346210.38822_3.mbp,U=8741:2,S 1532464801.21057_1.mbp,U=9028:2,S 1532464801.21057_2.mbp,U=9029:2,S
Let's sync the local changes.

fitbit API, org babel, and gnuplot
Retook running recently. Took the dust off my aria scale and used the opportunity to check out fitbit's API.
First register your app at dev.fitbit.com/apps/new and get a client_id=AABBCC.
You'll also need your USER_ID, from your Fitbitx user profile.
We'll also need a token. I used the implicit grant flow URL in my browser and extracted access_token=TOKEN.
Now let's wire up two org source blocks to fetch the data and subsequently plot using gnuplot.
It's pretty neat. You can take the output from one source block and use it as input to another.
We use curl to fetch data from fitbit's API and pipe through jq and sed to massage the output format into two columns.
Note: Before using gnuplot in org babel, you'll need to install the gnuplot package and add to babel languages.
(use-package gnuplot :ensure t) (use-package ob :config (org-babel-do-load-languages 'org-babel-load-languages '((gnuplot . t))))

Fetching data and plotting through org babel and gnuplot is pretty sweet. I've barely scratched the surface. There's more at Org-babel-gnuplot and Plotting tables in Org-Mode using org-plot. Either way, this is another Emacs super power to keep in the toolbox.

Emacs utilities for your OS
Narrowing utilities are a wonderful way of increasing productivity. I have a few workflows using Emacs's Helm framework.
There are great productivity boosters like Alfred and Quicksilver for macOS, with batteries included.
If you're a tinkerer, you'd enjoy the powerful Hammerspoon. Like elisp gluing all things Emacs, Hammerspoon uses Lua to glue all things macOS. You can build your own narrowing utilities using chooser and a little Lua.
local chooser = hs.chooser.new(function(choice) hs.alert.show(choice['text']) end) chooser:choices({ { ["text"] = "Alfred\n", ["subText"] = "macOS only\n", }, { ["text"] = "Quicksilver\n", ["subText"] = "macOS only\n", }, { ["text"] = "Hammerspoon\n", ["subText"] = "macOS only\n", }, { ["text"] = "Emacs\n", ["subText"] = "is everywhere :)\n", }, }) chooser:show()
Howard Abrams's post on Capturing Content for Emacs inspired me to look at gluing Emacs and macOS to launch my own cross-platform narrowing utilities.
I've also taken this opportunity to look at Oleh Krehel's wonderful completion package: Ivy. We can use it to build a macOS narrowing utility.
Ivy is remarkably easy to use. Turns out, ivy-read is all you need. A simple Emacs completion can be accomplished with little elisp.
(ivy-read "Hello ivy: " '("One " "Two " "Three " "Four "))
Pretty nifty. Let's make this completion more accessible from the rest of the OS. To do so, we create a separate Emacs frame and make it pretty. We also want it to interact with the OS. We'll use ivy-read's :action to invoke a tiny bit of AppleScript.
Oh and we'll also use some funny quotes to tease ourselves about our beloved editor.
(with-current-buffer (get-buffer-create "*modal-ivy*") (let ((frame (make-frame '((auto-raise . t) (background-color . "DeepSkyBlue3") (cursor-color . "MediumPurple1") (font . "Menlo 15") (foreground-color . "#eeeeec") (height . 20) (internal-border-width . 20) (left . 0.33) (left-fringe . 0) (line-spacing . 3) (menu-bar-lines . 0) (minibuffer . only) (right-fringe . 0) (tool-bar-lines . 0) (top . 48) (undecorated . t) (unsplittable . t) (vertical-scroll-bars . nil) (width . 110))))) (set-face-attribute 'ivy-minibuffer-match-face-1 frame :background nil :foreground nil) (set-face-attribute 'ivy-minibuffer-match-face-2 frame :background nil :foreground "orange1") (set-face-attribute 'ivy-minibuffer-match-face-3 frame :background nil :foreground "orange1") (set-face-attribute 'ivy-minibuffer-match-face-4 frame :background nil :foreground "orange1") (set-face-attribute 'ivy-current-match frame :background "#ffc911" :foreground "red") (set-face-attribute 'minibuffer-prompt frame :foreground "grey") (let ((ivy-height 20) (ivy-count-format "")) (ivy-read "Emacs acronyms: " '(" Emacs: Escape-Meta-Alt-Control-Shift " " Emacs: Eight Megabytes And Constantly Swapping " " Emacs: Even a Master of Arts Comes Simpler " " Emacs: Each Manual's Audience is Completely Stupified " " Emacs: Eventually Munches All Computer Storage " " Emacs: Eradication of Memory Accomplished with Complete Simplicity " " Emacs: Easily Maintained with the Assistance of Chemical Solutions " " Emacs: Extended Macros Are Considered Superfluous " " Emacs: Every Mode Accelerates Creation of Software " " Emacs: Elsewhere Maybe All Commands are Simple " " Emacs: Emacs Makes All Computing Simple " " Emacs: Emacs Masquerades As Comfortable Shell " " Emacs: Emacs My Alternative Computer Story " " Emacs: Emacs Made Almost Completely Screwed " " Emacs: Each Mail A Continued Surprise " " Emacs: Eating Memory And Cycle-Sucking " " Emacs: Elvis Masterminds All Computer Software " " Emacs: Emacs Makes A Computer Slow" ) :action (lambda (funny-quote) (async-shell-command (format "osascript -e 'tell app \"System Events\" to display dialog \"%s\" buttons {\"OK\"}'" funny-quote))) :unwind (lambda () (shell-command "/Applications/Hammerspoon.app/Contents/Resources/extensions/hs/ipc/bin/hs -c 'backFromEmacs()'") (delete-frame) (other-window 1))))))
So where's all this going? I wrote a utility to extract all links from this page's org file and make them easily searchable from anywhere on macOS by invoking ⌥-W.
The keys are bound using Lua, Hammerspoon, and emacsclient. This works well on macOS, but there are alternatives for other operating systems.
hs.execute("emacsclient -ne \""..elisp.."\" -s /tmp/emacs*/server")
Here's the resulting utility in action:
These integrations look promising. They enable me to bring cross-platform Emacs utilities into areas I hadn't considered.

Trying out mu4e with mbsync
The email fun in Emacs continues. After a few weeks since I started using mu4e and offlineimap, I'm sold. Both are awesome. Mbsync is an offlineimap alternative. Despite resyncing all my mail, the transition was fairly smooth. Here's how…
Install isync (for mbsync)
brew install isync
Configure mbsync
Mbsync uses ~/.mbsyncrc
for configuration. Migrating ~/.offlineimaprc to ~/.mbsyncrc
looks like:
IMAPAccount Personal Host some.imap.host.com User your_user_name PassCmd "gpg --quiet --batch -d ~/.offlineimap_accountname.gpg" Port 993 SSLType IMAPS AuthMechs Login CertificateFile ~/.offlineimapcerts.pem # My IMAP provider doesn't handle concurrent IMAP commands. PipelineDepth 1 IMAPStore Personal-remote Account Personal MaildirStore Personal-local Path ~/IMAP/Personal/ Inbox ~/IMAP/Personal/INBOX Channel Personal Master :Personal-remote: Slave :Personal-local: Patterns * Create Slave Sync All Expunge Both SyncState *
No concurrent IMAP commands supported
My IMAP provider doesn't handle concurrent IMAP commands. mbsync and Office 365 had the answer:
PipelineDepth 1
Initial sync
Run initial from the command line sync:
mbsync -Va
While syncing my largest inbox, it sometimes received an unexpected EOF error:
IMAP error: unexpected EOF from some.imap.host.com (1.2.3.4:993)
First few times, I restarted the syncing manually, but then used a loop to automatically restart it.
Bash loops:
while true; do mbsync -V Personal; sleep 5; done
for i in {1..5}; do mbsync -V Personal; sleep 5; done
Eshell loop:
for i in (number-sequence 1 10) {mbsync -V Personal; sleep 5}
Create mu index
Reindex using mu, but first remove existing index for offlineimap messages:
rm -rf ~/.mu
Ok, do index now:
mu index --maildir=~/IMAP
Mu4e tweaks
The get mail command should now point to mbsync.
(csetq mu4e-get-mail-command "mbsync -Va")
I had issues with duplicate IDs after moving and deleting messages from mu4e. Migrating from offlineimap to mbsync for mu4e had the answer:
(csetq mu4e-change-filenames-when-moving t)

Sticky function keys on touch bar
Visible (and sticky) function keys are not the touch bar default for Emacs. Let's change that:
GNU find on macOS
At times, you may need GNU versions of command line utilities on macOS. For example, GNU find.
As usual, Homebrew saves the day. Install with:
brew install findutils
Unless you install with –with-default-names (I don't), GNU utilities will be prefixed with a "g".
gfind --version

Adding mu4e maildirs extension
Continuing the mu4e fun, added mu4e-maildirs-extension to display a mail dirs summary.
Trying out mu4e and offlineimap
Managing Email from Emacs. Surely that's crazy-talk, but hey… let's give it a try.
Install offlineimap
Need to sync via imap. Use offlineimap. I'm on macOS, so homebrew is king for installing:
brew install offlineimap
Before can configure offlineimap, we'll need to handle a few things first.
Get a cert fingerprint
Use openssl for getting a certificate fingerprint. From offlineimap's FAQ:
SSL_CERT_DIR="" openssl s_client -connect imap.migadu.com:993 < /dev/null 2>/dev/null | openssl x509 -fingerprint -noout -text -in /dev/stdin
Should give you something like:
SHA1 Fingerprint=AA:BB:CC:DD:EE:DD:FF:AA:00:AA:2A:AA:AA:AA:A8:20:80:AA:A2:AA
Encrypt password
Offlineimap can read passwords in plain text in its .offlineimaprc config file, but that's yuckie. Let's encrypt the password and use gnupg for that. Install it:
brew install gnupg
If you haven't already, generate a key
gpg --full-gen-key
Generate an offlineimap account password file.
echo "YourPassword" | gpg --encrypt --recipient "Your Name" -o ~/.offlineimap_accountname.gpg
Python password wrapper
Based on Fabian's Encrypt OfflineIMAP and msmtp password with GnuPG, I created ~/.read_password.py with:
import os import subprocess def read_password(path): return subprocess.check_output(["gpg\n", "--quiet\n", "--batch\n", "-d\n", os.path.expanduser(path)]).strip()
ps. Alternatively, see The homely Mutt's section to store password in macOS's keychain.
Configure offlineimap
Offlineimap uses ~/.offlineimaprc for configuration. We now have all we need to put the configuration together:
[general] accounts = Personal # Load this python file. pythonfile = ~/.read_password.py [Account Personal] localrepository = Personal-Local remoterepository = Personal-Remote # After syncing, let mu index it. postsynchook = mu index --maildir ~/stuff/active/Mail # Sync imap every 5 minutes. autorefresh = 5 # Alternate between 10 quick syncs and full syncs. quick = 10 [Repository Personal-Local] type = Maildir localfolders = ~/stuff/active/Mail/Personal [Repository Personal-Remote] type = IMAP remotehost = some.imap.host.com remoteuser = your_user_name # Use function defined in .read_password.py to read the password. remotepasseval = read_password("~/.offlineimap_personal_account_password.gpg") # Use the SHA1 fingerprint retrieved with openssl. cert_fingerprint = aabbccddeeddffaa00aa2aaaaaaaa82080aaa2aa
Cert file
You can use macOS's certificates from Keychain Access -> System Roots -> Certificates, select all, and ⌘-⇧-e (for export items). Save to ~/certs.pem and use offlineimap configutation:
sslcacertfile = /path/to/certs.pem
Another option is executing lib/mk-ca-bundle.pl from curl's tarball to generate ca-bundle.crt, using certdata.txt from Mozilla's source tree.
Install mu4e
Manually modified mu4e recipe to pick up my Emacs binary. TIL about homebrew's edit command:
brew edit mu
Changed the one line:
- ENV["EMACS"] = "no" if build.without? "emacs"
- ENV["EMACS"] = "/Users/alvaro/homebrew/Cellar/emacs-plus/26.1-rc1_2/bin/emacs"
Finally installed mu4e:
brew install mu
Configure mu4e
Lastly, configure mu4e:
(add-to-list 'load-path (expand-file-name "~/homebrew/share/emacs/site-lisp/mu/mu4e")) (use-package mu4e :config ;; Update mail using 'U' in main view: (setq mu4e-get-mail-command "offlineimap") (setq mu4e-view-show-addresses t) (setq mu4e-attachment-dir (expand-file-name "~/Downloads/")) (setq mu4e-maildir "path/to/Mail") (setq mu4e-html2text-command "w3m -T text/html") ;; alternatively "textutil -stdin -format html -convert txt -stdout" (setq mu4e-user-mail-address-list '("myself@domain1.com" "myself@domain2.com")) (setq mu4e-context-policy 'pick-first) (setq mu4e-compose-context-policy 'always-ask) (setq mu4e-contexts (list (make-mu4e-context :name "domain1" :enter-func (lambda () (mu4e-message "Entering context myself@domain1.com")) :leave-func (lambda () (mu4e-message "Leaving context myself@domain1.com")) :match-func (lambda (msg) (when msg (mu4e-message-contact-field-matches msg '(:from :to :cc :bcc) "myself@domain1.com"))) :vars '((user-mail-address .

"smtp.domain2.com") (smtpmail-smtp-service . 587)))))) (use-package smtpmail :config (setq smtpmail-stream-type 'starttls) (setq smtpmail-debug-info t) (setq smtpmail-warn-about-unknown-extensions t) (setq smtpmail-queue-mail t) (setq smtpmail-default-smtp-server nil) ;; Created with mu mkdir path/to/Mail/queue ;; Also avoid indexing. ;; touch path/to/Mail/queue/.noindex (setq smtpmail-queue-dir "path/to/Mail/queue/cur")) (use-package message :config (setq message-send-mail-function 'smtpmail-send-it))
Authinfo
Create an ~/.authinfo file for sendmail authentication with:
machine smtp.host1.com login account1@host1.com password somepassword1 machine smtp.host2.com login account2@host2.com password somepassword2
Encrypt ~/.authinfo with M-x epa-encrypt-file. Keep ~/.authinfo.gpg and delete ~/.authinfo.

Pre-commit hooks to save you from yourself
Wanted to try out some code, but needed to ensure never checked in. Git pre-commit hooks are handy in this space. Add the following script to search for either @COMMITFAIL or @NOCOMMIT in the staged files. If found, attempts to commit will fail.
Based on https://gist.github.com/rex/223b4be50285f6b8b3e06dea50d15887:
#!/bin/bash set -o nounset set -o errexit echo "Arguments:" echo "$@" echo "---" readonly FILES_PATTERN='(\..+)?$' readonly FORBIDDEN='(@?NOCOMMIT|@?COMMITFAIL)' if ( git diff --cached --name-only | grep -E "$FILES_PATTERN" | xargs grep -E --with-filename -n "$FORBIDDEN" ); then echo "ERROR: @COMMITFAIL or @NOCOMMIT found. Exiting to save you from yourself." exit 1 fi
Save to a file and create a symbolic link to your .git/hooks directory:
ln -s ../../git/commit-fail-pre-hook.sh .git/hooks/pre-commit

Eshell pcomplete company completion
Howard Abrams's Introduction to eshell video prompted me to poke at eshell some more. This time, I got eshell context aware completion by glueing the excellent company and pcomplete packages.
(require 'cl-lib) (require 'company) (require 'dash) (require 'pcomplete) (require 's) (defun company-pcomplete--overlap-tail (a b) "When A is \"SomeDev\" and B is \"Developer\", return \"eloper\"." (let ((prefix a) (remaining nil)) (while (and (not remaining) (> (length prefix) 0)) (when (s-starts-with? prefix b) (setq remaining (substring b (length prefix)))) (setq prefix (substring prefix 1))) remaining)) (defun company-pcomplete--candidates (prefix) "Get candidates for PREFIX company completion using `pcomplete'." ;; When prefix is: "~/Down" and completion is "Downloads", need ;; to find common string and join into "~/Downloads/". (-map (lambda (item) (if (s-starts-with? prefix item) item (concat prefix (company-pcomplete--overlap-tail prefix item)))) (all-completions prefix (pcomplete-completions)))) (defun company-pcomplete (command &optional arg &rest ignored) "Complete using pcomplete. See `company''s COMMAND ARG and IGNORED for details." (interactive (list 'interactive)) (case command (interactive (company-begin-backend 'company-pcomplete)) (prefix (company-grab-symbol)) (candidates (company-pcomplete--candidates arg))))
Don't forget to add company-pcomplete to company-backends, and if you want an explicit binding, use something like:
(bind-key "<backtab>" #'company-complete eshell-mode-map)
Projectile shell dir company completion
Projectile and company are just amazing Emacs packages. Projectile gives random access to files, while company completes well… anything. For shells, Emacs has a handful of options.
Standing on the shoulders of package giants (dash and f included) and some elisp, we can bring random access to project directories from the shell.

Forcing aptX on MacOS bluetooth audio
Bought a pair of QuietComfort 35. Audio quality on MacOS was lagging compared to iOS. Googling led to different posts suggesting the use of Bluetooth Explorer to force aptX usage. Did the trick for me.
Bluetooth Explorer can be downloaded from https://developer.apple.com/download/more. Search for Hardware IO tools:
Open Hardware_IO_Tools_for_Xcode_7.3.dmg and launch Bluetooth Explorer:

GnuPG and macOS
Had problems installing and using GnuPG on macOS, primarily for Emacs use:
gpg: problem with the agent: Inappropriate ioctl for device gpg: error creating passphrase: Operation cancelled gpg: symmetric encryption of '[stdin]' failed: Operation cancelled
Basic installation required:
brew install gnupg
But worked around the error above by using pinentry-mac (UI), instead of Emacs prompts.
brew install pinentry-mac
Edited ~/.gnupg/gpg-agent.conf with:
pinentry-program path/to/homebrew/bin/pinentry-mac
May need to kill gpg-agent to reload config.
gpgconf --kill gpg-agent
Installing gnuplot on macOS
UPDATE(2019-05-19 Sun): Plan A and B use options no longer available since the recent changes to remove all options from Homebrew/homebrew-core formulae. See Plan C.
Plan A
Install gnuplot Qt
If you have the resources, you can try the Qt flavor. You need at least 15GB to download and a long build. Ran out of space on my Macbook Air. Aborted.
brew install gnuplot --with-qt
Plan B
Install xquartz
brew install Caskroom/cask/xquartz
Install gnuplot x11
brew install gnuplot --with-x11
Install feedgnuplot
Feedgnuplot is handy for plotting data streams realtime.
brew install feedgnuplot
Plan C
Install with no options
brew install gnuplot
So far so good, but default gnuplot formula uses Qt and the Cocoa plugin could not be loaded:
qt.qpa.plugin: Could not find the Qt platform plugin "cocoa" in ""
Debugging
- QT_DEBUG_PLUGINS
Turns out you can get plugin logs using the QT_DEBUG_PLUGINS environment variable:
export QT_DEBUG_PLUGINS=1
QFactoryLoader::QFactoryLoader() checking directory path "/Users/myuser/homebrew/Cellar/gnuplot/5.2.6_1/libexec/gnuplot/5.2/platforms" …
This led me to find out about the gnuplot/5.2/gnuplot_qt binary.
- qt_prfxpath
Getting the Qt prefix can be done by inspecting QtCore's strings:
strings /Users/myuser/homebrew/Cellar/qt/5.12.3/Frameworks/QtCore.framework/QtCore | grep qt_prfxpath
qt_prfxpath=/usr/local/Cellar/qt/5.12.3
Ok so qt_prfxpath is pointing to /usr/local/Cellar/qt, while my installation's is at /Users/myuser/homebrew/Cellar/qt. This is problematic and indeed my fault for installing homebrew in /Users/myuser/homebrew instead of the recommended /usr/local.
Symlinking did the job:
sudo mkdir -p /usr/local/Cellar sudo ln -s ~/homebrew/Cellar/qt /usr/local/Cellar/qt
/Users/myuser/homebrew/Cellar/gnuplot/5.2.6_1/libexec/gnuplot/5.2/gnuplot_qt
QFactoryLoader::QFactoryLoader() checking directory path "/Users/myuser/homebrew/Cellar/qt/5.12.3/plugins/platforms" ... QFactoryLoader::QFactoryLoader() looking at "/Users/myuser/homebrew/Cellar/qt/5.12.3/plugins/platforms/libqcocoa.dylib" Found metadata in lib /Users/myuser/homebrew/Cellar/qt/5.12.3/plugins/platforms/libqcocoa.dylib
Success.

Fuzzy search Emacs compile history
I wrote about searching bash history with Emacs Helm some time ago. Since then, I've learned about completing-read to generically handle simple Emacs completions (very handy for supporting Helm, Ivy, and Ido completions).
Here's a simple way to combine completing-read and the compile command to enable fuzzy searching your compile history:
(defun ar/compile-completing () "Compile with completing options." (interactive) (let ((compile-command (completing-read "Compile command: " compile-history))) (compile compile-command) (add-to-list 'compile-history compile-command)))
Jumping on the Emacs 25 bandwagon
Can't miss out on all the new fun. Emacs 25 RC2 is out and lots of people already using it. Since I'm mostly on MacOS these days, installing via homebrew with –devel, gets you RC2:
brew install emacs --devel --with-cocoa --with-gnutls --with-librsvg --with-imagemagick
The only hiccup so far's been org mode failing to export, which was fixed by re-installing it (follow this thread).

Emacs and emotional vocab
Having read Are You in Despair? That’s Good, I was encouraged to expand my emotional vocabulary. As a zone.el fan (checkout nyan, sl, and rainbow), I looked into writing a zone program. When zone-when-idle is set, zone acts as a screensaver of sorts. We can use this to display random emotional vocab whenever Emacs is idle for a period of time. Let's get to it…
Zone keeps a list of programs to choose from when kicked off. Below is a basic zone-hello program, along with an interactive command for previewing. Not much to these. The tiny program prepares the screen for zoning and inserts text while no input is pending.
(defun zone-hello () (delete-other-windows) (setq mode-line-format nil) (zone-fill-out-screen (window-width) (window-height)) (delete-region (point-min) (point-max)) (goto-char (point-min)) (while (not (input-pending-p)) (insert "hello zone\n") (zone-park/sit-for (point-min) 0.2))) (defun zone-hello-preview () (interactive) (let ((zone-programs [zone-hello])) (zone)))
Here's what zone-hello looks like:
Back to improving our emotional vocabulary, we'll need a dictionary for our goal. A quick search yields a potential list of words. We can use WordNet to define them while offline. These two sources will do for now. We tie it all together in zone-words.el and the resulting zone program looks as follow:
UPDATE: Just came across Animations With Emacs. A post with awesome zone examples.
Emacs: Find number of days between dates
Needed to find the number of days between two dates. Emacs calendar must know this…
- Fire up the manual (M-x info-emacs-manual or C-h r).
- Info-goto-node (or g).
- Type "counting days" and voilá:
To determine the number of days in a range, set the mark on one date using `C-<SPC>', move point to another date, and type `M-=' (`calendar-count-days-region'). The numbers of days shown is inclusive; that is, it includes the days specified by mark and point.
Note: you can use the mouse to jump to another date, or "g d" (calendar-goto-date).

Generating a random MAC address
As some point I had to generate a random MAC address. This is the snippet I used:
import random def randomMAC(): mac = [0x00, 0x16, 0x3e, random.randint(0x00, 0x7f), random.randint(0x00, 0xff), random.randint(0x00, 0xff), ] return ':'.join(map(lambda x: "%02x" % x, mac)) print 'MAC => %s' % randomMAC()
MAC => 00:16:3e:7e:f7:fa
Defined elisp variables matching regexp
You can use "M-x apropos-variable" to get documentation for variables matching a pattern. For more flexibility, some elisp can help with getting a list of all variables matching a regexp:

(when (and (boundp symbol) (string-match pattern (symbol-name symbol))) (add-to-list 'matched-variables symbol)))) matched-variables)) (let ((variables "")) (mapc (lambda (variable-symbol) (setq variables (concat variables (format "%s => %s\n" (symbol-name variable-symbol) (symbol-value variable-symbol))))) (ar/variables-matching-pattern "^tern-.*")) variables)
tern-mode-keymap => (keymap (3 keymap (4 . tern-get-docs) (3 . tern-get-type) (18 . tern-rename-variable)) (27 keymap (44 . tern-pop-find-definition) (67108910 . tern-find-definition-by-name) (46 . tern-find-definition))) tern-update-argument-hints-async => nil tern-known-port => nil tern-mode => nil tern-activity-since-command => -1 tern-project-dir => nil tern-last-point-pos => nil tern-last-completions => nil tern-explicit-port => nil tern-idle-time => 2.5 tern-find-definition-stack => nil tern-last-argument-hints => nil tern-idle-timer => nil tern-server => nil tern-last-docs-url => nil tern-buffer-is-dirty => nil tern-command-generation => 0 tern-flash-timeout => 0.5 tern-update-argument-hints-timer => 500 tern-mode-hook => nil tern-command => (tern)

Doh! undo last commit (Magit edition)
I previously noted how to undo your last git commit (ie. soft reset). Using Magit:
- M-x magit-log-current.
- Move point to prior revision.
- M-x magit-reset-soft (defaults to revision at point).
Or if you want a single function:
(require 'magit) (defun ar/magit-soft-reset-head~1 () "Soft reset current git repo to HEAD~1." (interactive) (magit-reset-soft "HEAD~1"))

Fischer's London: yes, but…
Yes
Step into a Viennese blast from the past. Beautiful setting and pleasant vibe. Ordered a dirty martini on the rocks, a bottle of Merlot, Käsespätzle (with bacon), and Wiener Schnitzel (with anchovy/capers/egg). All very tasty.
But…
Surprisingly, desserts (Topfenstrudel, Berggasse and coffee) were nothing spectacular. Also not a cheap eat (£50 per person).

Chocolate fondant recipe
My girlfriend recently made a delicious chocolate fondant. Saving the The Guardian's recipe:
Ingredients (2 servings)
- 60g unsalted butter, cut into dice, plus extra to grease
- 1 tbsp cocoa powder
- 60g dark chocolate, broken into pieces
- 1 egg and 1 egg yolk
- 60g caster sugar
- 1 tbsp plain flour
Preparation
- Pre-heat the oven to 200C if cooking immediately, and put a baking tray on the middle shelf. Butter the inside of 2 small ramekins or pudding moulds, and then put the cocoa in one and turn it to coat the inside, holding it over the second mould to catch any that escapes. Do the same with the other mould.
- Put the butter and chocolate into a heatproof bowl set over, but not touching, a pan of simmering water and stir occasionally until melted. Allow to cool slightly.
- Vigorously whisk together the egg, yolk, sugar and a pinch of salt until pale and fluffy. Gently fold in the melted chocolate and butter, and then the flour. Spoon into the prepared moulds, stopping just shy of the top – at this point the mixture can be refrigerated until needed, or even frozen, as the puddings will not wait around once cooked.
- Put on to a hot baking tray and cook for 12 minutes (14 if from cold, 16 if frozen) until the tops are set and coming away from the sides of the moulds. Leave to rest for 30 seconds and then serve in the ramekins or turn out on to plates if you're feeling confident – they're great with clotted cream or plain ice cream.

Import UIKit for simpler debugging
I bookmarked An @import-ant Change in Xcode and immediately forgot about it. The gist is to import UIKit to simplify inspecting objects during an lldb session:
(lldb) expr @import UIKit
Shorten typing by creating aliases in ~/.lldbinit:
command alias uikit expr @import UIKit command alias foundation expr @import Foundation

Basic Emacs keybindings on Linux desktop
Miss C-a, C-e in your browser and other Linux apps? You can enable the GTK Emacs key theme:
$ gsettings set org.gnome.desktop.interface gtk-key-theme "Emacs"
or if on Cinnamon:
$ gsettings set org.cinnamon.desktop.interface gtk-key-theme Emacs
If your desktop environment is not running gnome-settings-daemon, start it with:
$ gnome-settings-daemon

Emacs Objective-C completion with Irony
Install libclang on Mac
brew install llvm --with-clang
Configure Emacs
(use-package irony :ensure t :config (add-hook 'objc-mode-hook 'irony-mode) (add-hook 'irony-mode-hook 'irony-cdb-autosetup-compile-options)) (use-package company-irony :ensure t :config (add-hook 'objc-mode-hook (lambda () (setq-local company-backends '((company-irony))))) (add-hook 'irony-mode-hook 'company-irony-setup-begin-commands))
install irony server
Run:
M-x irony-install-server
NOTE: Needs libclang: Install with "brew install llvm –with-clang" By default, irony-install-server did not find libclang on Mac OS. irony-install-server invokes cmake for you. Work around by adding:
-DCMAKE_PREFIX_PATH=/Users/your-user-name/homebrew/opt/llvm
For example:
cmake -DCMAKE_PREFIX_PATH=/Users/your-user-name/homebrew/opt/llvm -DCMAKE_INSTALL_PREFIX\=/Users/your-user-name/.emacs.d/irony/ /Users/your-user-name/.emacs.d/elpa/irony-20160106.1223/server && cmake --build . --use-stderr --config Release --target install

Gandhi's ever-contemporary wisdom
Anger
"I do get angry, but I feel angry with myself for it. Full conquest of anger is possible only through self-realization. We should love even those who have the worst opinion of us. This is ahimsa, the rest is only ignorance."
Bad handwriting
"I am now of opinion that children should first be taught the art of drawing before learning how to write. Let the child learn his letters by observation as he does different objectives, such as flowers, birds, etc., and let him learn handwriting only after he has learned to draw objects."
Conduct of the Ashram
"Service without humility is selfishness and egotism."
Eating
"There is a great deal of truth in the saying that man becomes what he eats. The grosser the food, the grosser the body."
Heart
"There are chords in every human heart. If we only know how to strike the right chord, we bring out the music."
Moral law
The law of truth and love.
Renouncing or forgoing
Nishkulanand sings: "Renunciation of objects, without the renunciation of desires, is short-lived, however hard you may try."
Silence
"Man spoils matters much more by speech than by silence."
Time
"Every minute that runs to waste never returns. Yet, knowing this, how much time do we waste?"
The palate
"Turn to the birds and beasts, and what do you find? They never eat merely to please the palate, they never go on eating till their inside is full to overflowing. And yet, we regard ourselves as superior to the animal creation!"
Vow of Swadeshi
"The person who has taken the vow of swadeshi will never use articles which conceivably involve violation of truth in their manufature or on the part of their manufacturers."

Find in $PATH with type and which
I typically use which to figure out the first binary found in $PATH:
which -a emacsclient

I always forget about type though:
type -a emacsclient
emacsclient is /Users/user/homebrew/bin/emacsclient emacsclient is /usr/bin/emacsclient

Following up from changing CWD with helm projectile, here's a way to search your bash history with helm:
(defun ar/helm-helm (title candidates on-select-function) "Helm with TITLE CANDIDATES and ON-SELECT-FUNCTION." (helm :sources `((name . ,title) (candidates . ,candidates) (action . ,on-select-function)) :buffer "*helm-exec*" :candidate-number-limit 10000)) (defun ar/shell-send-command (command) "Send COMMAND to shell mode." (assert (string-equal mode-name "Shell") nil "Not in Shell mode") (goto-char (point-max)) (comint-kill-input) (insert command) (comint-send-input)) (defun ar/helm-shell-search-history () "Narrow down bash history with helm."

Bonus: Replace existing M-r binding to use ar/helm-shell-search-history.
(bind-key "M-r" #'ar/helm-shell-search-history shell-mode-map)

View DICOM files from your X-ray
Got a CD with my chest X-ray from the hospital. Was expecting a pdf or an image of sorts, but the CD content was rather different. For starters, it was targeted at Windows users (AUTORUN.INF, MediaViewerLauncher.EXE and a bunch of DLLs):
$ find . -exec file --mime-type '{}' \; ./AUTORUN.INF: text/plain ./DICOMDIR: application/dicom ./MediaViewerLauncher.EXE: application/octet-stream ... ./Libraries/BASEPRINTER.DLL: application/octet-stream ./Libraries/CDDATABURNER.DLL: application/octet-stream ./Libraries/COM.DLL: application/octet-stream ... ./Libraries/ACE.DLL: application/octet-stream ./Libraries/ACE_SSL.DLL: application/octet-stream ./Libraries/ATL90.DLL: application/octet-stream ... ./DICOM/PAT_0000: application/x-directory ./DICOM/PAT_0000/STD_0000/SER_0000/OBJ_0001/IM_0001: application/dicom ./DICOM/PAT_0000/STD_0000/SER_0001/OBJ_0001/ED_0001: application/dicom ./DICOM/PAT_0000/STD_0000/SER_0002/OBJ_0001/ED_0001: application/dicom ./Worklist/ClinicalInfo/067eccde-b299-e511-9114-005056ad3afe.mht: text/html ./Worklist/Report/067eccde-b299-e511-9114-005056ad3afe.mht: text/html ./Worklist/Worklist.wl: application/octet-stream
I'm on a Mac, so most of these files were not useful to me. The more interesting files were IM_0001 and ED_0001 with "application/dicom" MIME type. DICOM files stand for Digital Imaging and Communications in Medicine. How to view these on a Mac? OsiriX viewer is an option. OsiriX, though on the heavy side (100.7MB download), it rendered the X-ray successfully.
Unsurprisingly, ImageMagick's convert utility also handles DICOM files. Converting to PNG worked well.
$ convert ./DICOM/PAT_0000/STD_0000/SER_0001/OBJ_0001/ED_0001 ED_0001.png
DICOM files also hold patient's metadata and optional reports. The file format is well known. OsiriX gives you access to it, but a few lines of python can also extract it for you. First install the pydicom package:
$ sudo pip install pydicom
Running the python interpreter is enough to peak at the metadata:
>>> import dicom >>> ds = dicom.read_file("./DICOM/PAT_0000/STD_0000/SER_0000/OBJ_0001/IM_0001") >>> ds
(0008, 0000) Group Length UL: 400 (0008, 0005) Specific Character Set CS: 'ISO_IR 100' (0008, 0016) SOP Class UID UI: Computed Radiography Image Storage (0008, 0020) Study Date DA: '20151203' (0008, 0021) Series Date DA: '20151203' (0008, 0023) Content Date DA: '20151203' (0008, 0030) Study Time TM: '120519.000000' (0008, 0031) Series Time TM: '120520.000000' (0008, 0033) Content Time TM: '120643.000000' (0008, 0060) Modality CS: 'CR' (0008, 0070) Manufacturer LO: 'Canon Inc.' ...
There were other DICOM files with a report:
>>> import dicom >>> ds = dicom.read_file("./DICOM/PAT_0000/STD_0000/SER_0001/OBJ_0001/ED_0001") >>> ds
(0008, 0005) Specific Character Set CS: 'ISO_IR 100' (0008, 0016) SOP Class UID UI: Encapsulated PDF Storage ... (0042, 0012) MIME Type of Encapsulated Document LO: 'application/pdf'
DCMTK is another alternative tool to extract DICOM metadata. The source is available and can be built:
$ tar xf dcmtk-3.6.0.tar.gz $ cd dcmtk-3.6.0 $ cmake . $ make
Or installed via homebrew:
$ brew install dcmtk
DCMTK includes dcmdump. You can use it to dump DICOM files:
$ dcmdata/apps/dcmdump DICOM/PAT_0000/STD_0000/SER_0000/OBJ_0001/IM_0001

Soundcloud's Go best practices (GopherCon 2014)
Having watched the video, some takeaways:
Single GOPATH
$GOPATH/src/github.com/soundcloud/foo
Repo structure
Formatting and style
Use gofmt.
Google's codereview guidelines.
Avoid named return parameters.
Avoid make and new (unless you know sizes).
Use struct{} for sentinel values: sets, signal chans.
Flags
func main() { var ( foo = flags.String("foo\n", "doch\n", "...") bar = flat.Int("bar\n", 34, "...") ) flag.Parse() // ... }
Logging
Testing
Code validation
Sync pip with Mac OS updates

Updating my pip installation fixes the break:

Chinatown treats review
Recommended? yep
There's a corner in Chinatown hosting some truly superb treats. If you get caught in the rush between Newport court and Newport place, you'd likely fail to notice some the awesome street food stands.
Chilly squid
I've walked past this place many times and never noticed it. They serve a handful of items, but the grilled chilly squid skewers caught my attention. They're grilled, brushed with chilly sauce and finished with sprinkled sesame and cumin seeds. Super tasty.
Pancake + Crisp + Egg + Hot chillies = Jiān Bǐng 煎餅
I first had these delicious breakfast savory pancakes at a Beijing street food stall. Never expected to randomly find Jiān Bǐng in London. It's a crepe with an additional egg spread, hoisin sauce, chilly sauce, hot chillies, topped with spring onions and coriander, all wrapping a wonderfully crispy bread cracker. And.. it's awesome.
Tai Yaki
Chinatown Bakery is hard to miss. Pedestrian traffic slows down as we all fall under the spell of the Tai Yaki machine. This wonderful assembly line produces fish-shaped sweet waffles filled with custard. They are the perfect dessert after some savory street snacks. You can get a bag of 4 for £2.
All near each other
All these delights are within a stone's throw away from each other.
Useful?
Was this post useful to you? do reply!
Better suggestion?
London is full of overhyped, gimmicky, and unnecessarily expensive restaurants. Very few deliver truly awesome food (even those expensive ones). Got suggestions? I'd love to hear from you @xenodium.

Lucky 7 review
Recommended? yep
Buttermilk Banana pancakes
These are my favorite pancakes in London by far. Banana buttermilk pancakes and a few free coffee refills usually sort me out until dinner time. Add a side of bacon if extra hungry. You probably don't need it though.
Reuben sandwich
The reuben has been on Lucky 7's specials menu for months now. Not had many of these in London, but compared to The Brass Rail's, this reuben was a clear winner. The sandwich is huge and comes with fries. My girlfriend and I struggled to finish one between the two of us.
Vanilla milkshake (add malt!)
This milkshake hits the spot every time, but it's filling. You almost have to decide between the shake and an actual meal. If you must have it, add malt. Sorry, no picture.
Huevos Rancheros
This is a breakfast dish I can equally make (better?) at home, but Lucky 7 wins hands down every time I'm feeling particularly lazy. Sorry, no picture.
Useful?
Was this post useful to you? do reply!
Better suggestion?
London is full of overhyped, gimmicky, and unnecessarily expensive restaurants. Very few deliver truly awesome food (even those expensive ones). Got suggestions? I'd love to hear from you @xenodium.

Upgrading PL30 headphones
I've loved my Soundmagic PL30 in-ear headphones. They're relatively inexpensive, comfortable, and great for exercising (they stay in). Audio quality and bass have been good enough (I don't need much). Unfortunately, I've had two pairs of PL30's and both stopped working after a year or two. I'm replacing the last pair with RHA's MA750 (an upgrade, me hopes).
Other contenders considered: Etymotic Research HF5, and Shure SE215. Also considered bluetooth alternatives like JayBird BlueBuds X and Plantronics BackBeat GO 2.
I'm somewhat nervous to pay more for a pair of headphones. Let's hope they don't meet the same unfortunate fate. We'll see.

Add site-specific browsers to your workflow
There are three browser tabs continously used in my workflow: GMail, Google Calendar, and Google Play Music. I normally have many more tabs open, but these three I access periodically. As the number of open tabs increases, and I fail to cleanup, getting back to my usual three gets a little trickier.
So far, I've kept each of these services open in separate windows. But that doesn't always work. Click on any link in your inbox and you're back to playing cleanup. This is where site-specific browsers (SSB) can help.
Epichrome enables you to build Chrome-based SSBs (on Mac OSX). Build an SSB for the usual suspects and easily jump to them using the app switcher.

UPDATE: Enable the Chrome extension to open URLs in default browser.

Recognize new password prompts in Emacs shell
At some point, you may come across a trusted command-line utility prompting you for a password, and Emacs shell happily displaying each typed character to the nearby-world to see. Luckily, you can train Emacs to recognize new password prompts and hide the typed characters in modes deriving from comint. Append the password prompt REGEXP:
(setq comint-password-prompt-regexp (concat comint-password-prompt-regexp "\\|" "Password for red alert:"))

Fishing with Emacs
OK not quite, but having recently learned about C-M-w (append-next-kill), I used it in a keyboard macro to fish out matching lines. This is similar to flush-lines, except the kill ring is also populated. This is handy, if you need the flushed lines. Here's an example.
Here's the equivalent in Emacs lisp:
(defun flush-kill-lines (regex) "Flush lines matching REGEX and append to kill ring. Restrict to \ region if active." (interactive "sFlush kill regex: ") (save-excursion (save-restriction (when (use-region-p) (narrow-to-region (point) (mark)) (goto-char 0)) (while (search-forward-regexp regex nil t) (move-beginning-of-line nil) (kill-whole-line)))))

Searchable ebooks in Emacs
If you haven't bought Mastering Emacs by Mickey Petersen, you should. It's a wonderful source of Emacs tips. Having just finished the ebook on my Kindle, I was keen to go back and fish out some of that newly found wisdom. My immediate reaction was to figure out a way to make the ebook searchable from Emacs.
The ebook is available in epub and pdf format. Though Emacs's docview is super handy for viewing pdf's, searching didn't feel as comfortable as searching in org mode. The epub, on the other hand, proved useful. Pandoc can easily convert from epub to org.
pandoc --from=epub --to=org mastering-emacs.epub > mastering-emacs.org
After a some tidying (mostly removing BEGIN_HTML/END_HTML blocks and adding TITLE/AUTHOR), the resulting org file is surprisingly clean and easy to search/navigate. helm-swoop and helm-org-in-buffer-headings are great for that.

Programmatic iOS Auto Layout
Basic iOS auto layout usage. See Adopting Auto Layout and Visual Format language for reference.
- (instancetype)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { // Disable autoresizing mask translation for parent. self.translatesAutoresizingMaskIntoConstraints = NO; _subview1 = [[UIView alloc] init]; // Disable autoresizing mask translation for subview. _subview1.translatesAutoresizingMaskIntoConstraints = NO; _subview1.backgroundColor = [UIColor redColor]; [self addSubview:_subview1]; // Creates a dictionary of bindings to be used in visual format. NSDictionary *viewBindings = NSDictionaryOfVariableBindings(_subview1); // H: horizontal layout // |-50- spacing in relation to superview // [_subview1(==50)] subview1's width [self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-50-[_subview1(==50)]" options:0 metrics:nil views:viewBindings]]; [self addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[_subview1(==50)]" options:0 metrics:nil views:viewBindings]]; } return self; }
Also consider:
- A UIView Subclass should implement intrinsicContentSize.
- A UIView Subclass should never add constraints on neither itself (ie. self) nor superview.

Development quotes
- If your backlog is exploding the problem is not that your developers are slow, but that your business model is not based on reality.
- If you lose out on object allocation, you still win by avoiding expensive re-renders and re-calculations.
- Duplication is far cheaper than the wrong abstraction (prefer duplication up to a point).
- Choosing an appropriate design to duplication avoid might benefit from more examples to see patterns in. Attempting premature refactoring risks selecting a wrong abstraction.
- Patterns failed, why we should case.
Development philosophy
- Boyscout rule: Leave campground cleaner than found.
- What can clang-format teach us about the human condition?.

Resetting variables using defvar
Want to re-evaluate defvars and modify variables? eval-defun (bound to C-M-x) can help. From the manual:
If the current defun is actually a call to `defvar', then reset the variable using its initial value expression even if the variable already has some other value. (Normally `defvar' does not change the variable's value if it already has a value.) Treat `defcustom' similarly.

(point-max))
- Restore point, mark, and current buffer:
(save-excursion (goto-char (point-max)) (insert "Hello elisp."))

Emacs key bindings and maps
based on masteringemacs.org.
bonus tip
prefix key, followed by c-h, lists keys in prefix.
keymap
maps key to action.
keymap found in buffer and most major modes.
keys
- undefined: self explanatory.
- prefix key: ie. c-x (part of complete key).
- complete key: complete input executes associated command.
mapping
- (define-key keymap key def): add to current buffer map.
- (local-set-key key command): add to active buffer (no map option).
- (local-unset-key key)
- (global-set-key key command): add to global keymap (all buffers).
- (global-unset-key key)
key codes
- kbd: macro transaltes human-readable key to emacs readable.
- function and navigation keys must be surrounded by <>.
- example: (kbd "c-c p") or (kbd "<f8>") of (kbd "<down>").
remapping
- use remap to replace mapping (ie. kill-line with my/kill-line).
- (define-key keymap [remap original-function] 'my-own-function).
reserved keys
- "c-c ?" generally reserved for you, but third party packages use it.
- function keys (ie. f1-f12).
- hyper and super (ancient).
lookup order
- in a nutshell: minor mode keys, local keys, global keys.
- full order:
- overriding-terminal-local-map: terminal-specific key binds.
- overriding-local-map: override all other local keymaps (avoid if possible).
- char property at point: useful for yasnippet.
- emulation-mode-map-alists: advanced multi-mode keymap.
- minor-mode-overriding-map-alist: minor modes in major modes.
- minor-mode-map-alist: as previous (preferred for minor modes) <–—
- current-local-map: buffers current local map.
- current-global-map: last place to look (ie. global).
mode hooks
- (local-set-key (kbd "c-c q") 'my-awesome-method)) in hook-method.
- for key-chord-define, use current-local-map.
