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)

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.

mbsync -Va

…and we're done ;)

• Below the Surface: The archaeological finds of the North / Southline in Amsterdam.

• Roman Zolotarev's OpenBSD on my fanless desktop computer (really sweet setup).

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))))

curl -s -H "Authorization: Bearer TOKEN" https://api.fitbit.com/1/user/USER_ID/body/weight/date/2018-06-09/2018-07-11.json | jq '.[][] | "\(.dateTime) \(.value)"' | sed 's/"//g'

Now feed the two column data to gnuplot.

reset
set title "My recent weight"
set xdata time
set timefmt '%Y-%m-%d'
set format x "%d/%m/%y"
set term png
set xrange ['2018-06-09':'2018-07-11']
plot data u 1:2 with linespoints title 'Weight in Kg'

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.

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",
         ["subText"] = "macOS only",
      },
      {
         ["text"] = "Quicksilver",
         ["subText"] = "macOS only",
      },
      {
         ["text"] = "Hammerspoon",
         ["subText"] = "macOS only",
      },
      {
         ["text"] = "Emacs",
         ["subText"] = "is everywhere :)",
      },
})
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.

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.

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…

Visible (and sticky) function keys are not the touch bar default for Emacs. Let's change that:

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".

  (add-to-list 'default-frame-alist '(ns-appearance . dark)) ; nil for dark text
  (add-to-list 'default-frame-alist '(ns-transparent-titlebar . t)))

Came across Lunette. Gives ya Spectacle Keybindings for Hammerspoon.

TIL about the openwith package. It enables Emacs to defer to external programs for certain files. You choose which ones. Neat.

(use-package openwith :ensure t
  :config
  (csetq openwith-associations
         '(("\\.\\(mp4\\|mp3\\|webm\\|avi\\|flv\\|mov\\)$" "open" (file))))
  (openwith-mode 1))

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

Came across a 404 while installing graphviz-2.40.1.tar.gz via homebrew. If you can find the package elsewhere, copy over to homebrew's cache directory.

Wanted to quickly execute an Objective-C snippet. org-babel didn't support it out of the box, but adding it was straightforward (looked at ob-C.el and ob-java.el):

(require 'ob)

(defcustom org-babel-objc-compile-command "clang -x objective-c -framework Foundation"
  "For example: \"clang -x objective-c -framework Foundation\"."
  :group 'org-babel
  :version "24.3"
  :type 'string)

(defun org-babel-execute:objc (body params)
  "Compile Objective-C BODY with org PARAMS and execute binary."
  (let* ((src-file (org-babel-temp-file "org-babel-objc-block-" ".m"))
         (cmpflag (or (cdr (assq :cmpflag params)) ""))
         (full-body (org-babel-expand-body:generic body params))
         (bin-file
          (org-babel-process-file-name
           (org-babel-temp-file "org-babel-objc-block" org-babel-exeext))))
    (with-temp-file src-file (insert full-body))
    (org-babel-eval
     (concat org-babel-objc-compile-command " " cmpflag " " src-file " " "-o" " " bin-file) "")

    ;; Using 2>&1 since org babel does not include stderr in output from NSLog.
    (let ((results (org-babel-eval (concat (org-babel-process-file-name bin-file) " 2>&1")  "")))
      (org-babel-reassemble-table
       (org-babel-result-cond (cdr (assq :result-params params))
         (org-babel-read results)
         (let ((tmp-file (org-babel-temp-file "c-")))
           (with-temp-file tmp-file (insert results))
           (org-babel-import-elisp-from-file tmp-file)))
       (org-babel-pick-name
        (cdr (assq :colname-names params)) (cdr (assq :colnames params)))
       (org-babel-pick-name
        (cdr (assq :rowname-names params)) (cdr (assq :rownames params)))))))

(provide 'ob-objc)

Add objc to org-babel-load-languages, and you can subsequently compile and run Objective-C blocks like:

#import <Foundation/Foundation.h>

int main() {
  NSLog(@"Hello World");
  return 0;
}

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."

  (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 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.

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.

Straight out of How (and why) I made a zine, some handy utilities for generating pdfs…

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)))

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).

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.

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).

RoutingHTTPServer snippet:

RoutingHTTPServer *routingHTTPServer = [[RoutingHTTPServer alloc] init];
[routingHTTPServer setPort:8000];
[routingHTTPServer setDefaultHeader:@"Server" value:@"YourAwesomeApp/1.0"];
[routingHTTPServer handleMethod:@"GET"
                       withPath:@"/hello"
                          block:^(RouteRequest *request, RouteResponse *response) {
    [response setHeader:@"Content-Type" value:@"text/plain"];
    [response respondWithString:@"Hello!"];
  }];
NSError *error = nil;
if (![routingHTTPServer start:&error]) {
  NSLog(@"Error starting HTTP Server: %@", error);

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

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:

(defun ar/variables-matching-pattern (pattern)
  "Get a list of all variables matching PATTERN."
  (let ((matched-variables '()))
    (mapatoms
     (lambda (symbol)
       ;; Symbol is variable?
       (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)

1. M-x magit-log-current.
2. Move point to prior revision.
3. M-x magit-reset-soft (defaults to revision at point).

Or if you want a single function:

(require 'magit)

  "Soft reset current git repo to HEAD~1."
  (interactive)
  (magit-reset-soft "HEAD~1"))

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)

        :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."

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):

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

There were other DICOM files with a report:

>>> ds = dicom.read_file("./DICOM/PAT_0000/STD_0000/SER_0001/OBJ_0001/ED_0001")

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:

Dart SDK ships with an analysis server. Very handy if you'd like to write a completion plugin for your favorite editor. The API is well documented. Of interest, there's LocalDartServer.java, part of dartedit.

$ dart path/to/bin/snapshots/analysis_server.dart.snapshot  --sdk=path/to/dart-sdk

NOTE: The server reads requests from standard input. Either escape or execute the following as one-liner json requests.

{
  "id": "1",
  "method": "analysis.setAnalysisRoots",
  "params": {
    "included": [

Is read from left to right as:

2.5 mile warm up to four times through 1.25 miles at 11.5 miles per hour with 0.25 miles recovery at 7 miles per hour to three times through 3.75 miles at 10.5 miles per hour with 0.5 miles recovery at 7 miles per hour to 2.5 miles cool down.

  (comint-kill-input)
  (insert (concat "cd " (shell-quote-argument dir-path)))
  (let ((comint-process-echoes t))
    (comint-send-input)))

(defun ar/helm-projectile-shell-cd ()
  "Change shell current working directory using helm projectile."
  (interactive)
  (unless (string-equal mode-name "Shell")
    (error "Not in Shell mode"))

    (add-to-list 'helm-dir-source '(action . ar/shell-cd))

Recently wanted to come up with a random keyword. Querying WordNet and a regular expression did the job.

Installed WordNet on Mac:

My pip installation recently broke after a Mac OS update.

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.

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.

Whether it's Makefile, SConstruct, BUILD, or your favorite build file, chances are you have to tweak it from time to time. ar/open-build-file searches your current and parent directories to find a build file.

(defvar ar/project-file-names '("Makefile" "SConstruct" "BUILD"))

(defun ar/parent-directory (path)
  "Get parent directory for PATH."
  (unless (equal "/" path)
    (file-name-directory (directory-file-name path))))

(defun ar/find-upwards (path filename)
  "Search upwards from PATH for a file named FILENAME."
  (let ((file (concat path filename))
        (parent (ar/parent-directory (expand-file-name path))))
    (if (file-exists-p file)
        file
      (when parent
        (ar/find-upwards parent filename)))))

(defun ar/open-closest (filename)
  "Open the closest FILENAME in current or parent dirs (handy for finding Makefiles)."
  (let ((closest-file-path (ar/find-upwards (buffer-file-name)
                                                 filename)))
    (when closest-file-path
      (message closest-file-path)
      (switch-to-buffer (find-file-noselect closest-file-path)))
    closest-file-path))

(defun ar/open-build-file ()
  "Open the closest project file in current or parent directory.
For example: Makefile, SConstruct, BUILD, etc.
Append `ar/project-file-names' to search for other file names."
  (interactive)
  (catch 'found
    (mapc (lambda (filename)

              (throw 'found t)))

Recently kept track of expenses between a group of us. To settle the scores, I emailed an exported HTML table from an org file. This was simple enough and required no external viewer from recepients. The org table, in all its textful glory, looked as follows…

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:"))
