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 'pcomplete)

(defun company-pcomplete--candidates ()
  "Get candidates company completion backed by `pcomplete'."
  (all-completions "" (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))))

(provide 'company-pcomplete)

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)

I'm finding Wilfred Hughes's helpful-mode, well… rather helpful. However, I'm missing imenu support. Here's a hacky way to get basic imenu.

(defun helpful--create-imenu-index ()
  "Create an `imenu' index for helpful."
  (beginning-of-buffer)
  (let ((imenu-items '()))
    (while (progn
             (beginning-of-line)
             ;; Not great, but determine if looking at heading:
             ;; 1. if it has bold face.
             ;; 2. if it is capitalized.
             (when (and (eq 'bold (face-at-point))
                        (string-match-p
                         "[A-Z]"
                         (buffer-substring (line-beginning-position)
                                           (line-end-position))))
               (add-to-list 'imenu-items
                            (cons (buffer-substring (line-beginning-position)
                                                    (line-end-position))
                                  (line-beginning-position))))
             (= 0 (forward-line 1))))
    imenu-items))

(defun helpful-mode-hook-function ()
  "A hook function for `helpful-mode'."
  (setq imenu-create-index-function #'helpful--create-imenu-index))

(add-hook 'helpful-mode-hook
          #'helpful-mode-hook-function)

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.

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).

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)

I previously noted how to undo your last git commit (ie. soft reset). Using Magit:

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)

(defun ar/magit-soft-reset-head~1 ()
  "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)
                   (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."
  (interactive)
  (assert (string-equal mode-name "Shell") nil "Not in Shell mode")
  (ar/helm-helm "bash history"
                (with-temp-buffer
                  (insert-file-contents "~/.bash_history")
                  (reverse
                   (delete-dups
                    (split-string (buffer-string) "\n"))))
                #'ar/shell-send-command))

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)

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:

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

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

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.

Comments in posts can be a great source of recommendations. Here's a way to extract post links using Emacs and enlive.

(require 'enlive) ;; https://github.com/zweifisch/enlive
(require 'org)


(defun ar/input-clipboard-url-or-prompt ()
  "Return a URL from clipboard or prompt user for one."

If using Emacs shell and helm projectile, you can wire these up to quickly change your current working directory.

(require 'helm-projectile)

  (unless (string-equal mode-name "Shell")
    (error "Not in Shell mode"))

  (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"))
  (let ((helm-dir-source (copy-tree  helm-source-projectile-directories-list)))
    (add-to-list 'helm-dir-source '(action . ar/shell-cd))
    (add-to-list 'helm-dir-source '(keymap . nil))
    (add-to-list 'helm-dir-source '(header-line . "cd to directory..."))
    (helm :sources helm-dir-source
          :buffer "*helm-dirs*"
          :candidate-number-limit 10000)))

My Bosch washer/dryer (WKD28350GB) stopped drying recently. Resetting the dryer's thermostat red breaker did the trick.

Playing with node and fetch:

// Requisite: npm install node-fetch --save
// Save to fetch-demo.js
// Run: node fetch-demo.js

var fetch = require('node-fetch');

fetch("http://xenodium.com/data/javascript-fetch-node-sample/message.json", {
  method: 'GET',
  timeout: 5000
}).then(function(response) {
  return response.json();
}).then(function(response) {
  console.log('subject: ' + response.subject);
  console.log('body: ' + response.body);
}).catch(function(reason) {
  console.log(reason);
});

There's a handy HN post pointing to Javier López's Using imagemagick, awk and kmeans to find dominant colors in images. A comment also highlights color-extract, written in Go.

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

Installed WordNet on Mac:

$ brew install wordnet

Want a word ending in "esome"?

$ wn esome -grepn -grepv -grepa -grepr | egrep -o -e "\w*esome\b" | sort | uniq

adventuresome
awesome
blithesome
bunglesome
cuddlesome
esome
fivesome
gruesome
lithesome
lonesome
lovesome
meddlesome
mettlesome
nettlesome
threesome
tiresome
torturesome
troublesome
unwholesome
venturesome
wholesome

Having watched the video, some takeaways:

My pip installation recently broke after a Mac OS update.

$ pip
Traceback (most recent call last):
  File "/usr/local/bin/pip", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2793, in <module>
    working_set.require(__requires__)

    needed = self.resolve(parse_requirements(requirements))

    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pip==1.1

Updating my pip installation fixes the break:

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.

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

Converting mp4 to gif is handy for posting short screencasts. You can convert to gif using ffmpeg and optimize with imagemagick. To install:

apt-get install ffmpeg imagemagick (linux)
brew install ffmpeg imagemagick (Mac)

Convert to gif:

ffmpeg -i my.mp4 -pix_fmt rgb24 -r 5 my.gif

Optimize with:

convert -dither none -layers Optimize my.gif my_optimized.gif

UPDATE: There's also licecap and subsequently optimize with:

cat source.gif | gifsicle --colors 256 --optimize=3 --delay=15 > target.gif

UPDATE: Also consider for .mov:

ffmpeg -i in.mov -pix_fmt rgb24 -r 10 -f gif - | gifsicle --optimize=3 --delay=3 > out.gif

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)))))

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.

Overriding retain/release/autorelease may be handy while debugging:

  [super release];
}
