Sacha Chua's Emacs configuration

Last exported: 2024-05-14 09:26

About this file

This is my personal config. It's really long, but that's partly because I sometimes leave blog posts in it as commentary, and also because I've got a lot of little customizations that I might not even remember. =) If you want to see a table of contents and other useful niceties, go to . Other links for this page: Org Mode version, Github repository

If you're new to Emacs Lisp, you probably don't want to copy and paste large chunks of this code. Instead, copy small parts of it (always making sure to copy a complete set of parentheses) into your *scratch* buffer or some other buffer in emacs-lisp-mode. Use M-x eval-buffer to evaluate the code and see if you like the way that Emacs behaves. See An Introduction to Programming in Emacs Lisp for more details on Emacs Lisp. You can also find the manual by using C-h i (info) and choosing "Emacs Lisp Intro".

I've installed a lot of packages. See the section to add the repositories to your configuration. When you see use-package and a package name you might like, you can use M-x package-install to install the package of that name.

If you're viewing the Org file, you can open source code blocks (those are the ones in begin_src) in a separate buffer by moving your point inside them and typing C-c ' (org-edit-special). This opens another buffer in emacs-lisp-mode, so you can use M-x eval-buffer to load the changes. If you want to explore how functions work, use M-x edebug-defun to set up debugging for that function, and then call it. You can learn more about edebug in the Emacs Lisp manual.

I like using (setq ...) more than Customize because I can neatly organize my configuration that way. Ditto for use-package - I mostly use it to group together package-related config without lots of with-eval-after-load calls, and it also makes declaring keybindings easier.

Here's my init.el:

(load-file "~/sync/emacs/Sacha.el")
(load-file "~/sync/cloud/.emacs.secrets")

(put 'narrow-to-region 'disabled nil)
(put 'list-timers 'disabled nil)
(server-mode 1)

Sacha.el is what M-x org-babel-tangle (C-c C-v t) produces.

A note about Org updates: I like running Org Mode from checked-out source code instead of package.el. I add the Lisp directories to my load-path, and I also use the :load-path option in my first use-package org call to set the load path. One of those is probably doing the trick and the other one is redundant, but maybe it's a belt-and-suspenders sort of thing. Using the git checkout also makes upgrading Org easy. All I have to do is git pull; make, and stuff happens in an external Emacs process. Since I create Sacha.el via org-babel-tangle, my Emacs config can load Sacha.el without loading Org first.

Debugging tips

If things break, I can use:

  • check-parens to look for mismatched parentheses
  • package:bug-hunter to bisect my configuration
  • trace-function-background to get information printed to a buffer
  • profiler-start to find out more about slow functions

Starting up

Here's how we start:

;; -*- lexical-binding: t -*-
;; This sets up the load path so that we can override it
(setq warning-suppress-log-types '((package reinitialization)))  (package-initialize)
(add-to-list 'load-path "/usr/local/share/emacs/site-lisp")
(add-to-list 'load-path "~/vendor/org-mode/lisp")
(add-to-list 'load-path "~/vendor/org-mode/contrib/lisp")
(setq custom-file "~/.config/emacs/custom-settings.el")
(setq use-package-always-ensure t)
(load custom-file t)

Emacs initialization

Add package sources

(unless (assoc-default "melpa" package-archives)
  (add-to-list 'package-archives '("melpa" . "") t))
(unless (assoc-default "nongnu" package-archives)
  (add-to-list 'package-archives '("nongnu" . "") t))

Use M-x package-refresh-contents to reload the list of packages after adding these for the first time.

Add my elisp directory and other files

Sometimes I load files outside the package system. As long as they're in a directory in my load-path, Emacs can find them.

(add-to-list 'load-path "~/elisp")
(setq use-package-verbose t)
(setq use-package-always-ensure t)
(require 'use-package)
(use-package quelpa)
(use-package quelpa-use-package)
(setq load-prefer-newer t)

Personal information

(setq user-full-name "Sacha Chua"
      user-mail-address "")

System information

(defvar my-laptop-p (equal (system-name) "sacha-x230"))
(defvar my-server-p (and (equal (system-name) "localhost") (equal user-login-name "sacha")))
(defvar my-phone-p (not (null (getenv "ANDROID_ROOT")))
  "If non-nil, GNU Emacs is running on Termux.")
(when my-phone-p (setq gnutls-algorithm-priority "NORMAL:-VERS-TLS1.3"))
(global-auto-revert-mode)  ; simplifies syncing


(defun my-reload-emacs-configuration ()
  (load-file "~/proj/.emacs.d/Sacha.el"))


This is one of the things people usually want to change right away. By default, Emacs saves backup files in the current directory. These are the files ending in ~ that are cluttering up your directory lists. The following code stashes them all in ~/.config/emacs/backups, where I can find them with C-x C-f (find-file) if I really need to.

(setq backup-directory-alist '(("." . "~/.config/emacs/backups")))
(with-eval-after-load 'tramp
  (add-to-list 'tramp-backup-directory-alist
               (cons tramp-file-name-regexp nil)))

Disk space is cheap. Save lots.

(setq delete-old-versions -1)
(setq version-control t)
(setq vc-make-backup-files t)
(setq auto-save-file-name-transforms '((".*" "~/.config/emacs/auto-save-list/" t)))



(setq savehist-file "~/.config/emacs/savehist")
(savehist-mode 1)
(setq history-length t)
(setq history-delete-duplicates t)
(setq savehist-save-minibuffer-history 1)
(setq savehist-additional-variables

Disabling the toolbar

When you're starting out, the tool bar can be very helpful. (Emacs Basics: Using the Mouse). Eventually, you may want to reclaim that extra little bit of screenspace. The following code turns that thing off. (Although I changed my mind about the menu - I want that again.)

(tool-bar-mode -1)

Change "yes or no" to "y or n"

Lazy people like me never want to type "yes" when "y" will suffice.

(fset 'yes-or-no-p 'y-or-n-p)

Minibuffer editing - more space!

Sometimes you want to be able to do fancy things with the text that you're entering into the minibuffer. Sometimes you just want to be able to read it, especially when it comes to lots of text. This binds C-M-e in a minibuffer) so that you can edit the contents of the minibuffer before submitting it.

(use-package miniedit
  :commands minibuffer-edit
  :init (miniedit-install))

Killing text

(setq kill-ring-max 1000)


(defadvice kill-region (before slick-cut activate compile)
  "When called interactively with no active region, kill a single line instead."
   (if mark-active (list (region-beginning) (region-end))
     (list (line-beginning-position)
           (line-beginning-position 2)))))

Extended command list

This code allows me to select a command from a short list of functions so that I can prompt my memory better. I wonder if this makes sense considering transient and hydra make keyboard shortcuts easier.

Emacs Hydra: Allow completion when I can't remember the command name

2021-04-29: Added the ability to complete using an arbitrary Hydra.

So it turns out that I'm pretty much zonked after a day with the kiddo and have a hard time remembering keystrokes or speed-reading my Hydra cheat sheets. I want to be able to use M-x-like completion in my Hydra so that I can type a few characters and then maybe see the shortcuts there. Here's what it looks like:

Figure 1: Hydra completion
(defun my-hydra-format-head (h)
  (let ((key-binding (elt h 0))
        (hint (elt h 2))
        (cmd (and (elt h 1) (prin1-to-string (elt h 1)))))
    (if cmd
        (format "%s (%s) - %s" hint key-binding cmd)
      (format "%s (%s)" hint key-binding))))

(defun my-hydra-heads-to-candidates (base)
  (mapcar (lambda (h)
            (cons (my-hydra-format-head h) (hydra--head-name h base)))
          (symbol-value (intern (concat (symbol-name base) "/heads")))))

(defun my-hydra-execute-extended (&optional _ hydra-base)
  (interactive (list current-prefix-arg nil))
  (let* ((candidates (my-hydra-heads-to-candidates
                      (or hydra-base
                           (replace-regexp-in-string "/body$" ""
                                                     (symbol-name hydra-curr-body-fn))))))
         (command-name (completing-read "Cmd: " candidates))
         (bind (assoc-default command-name candidates 'string=)))
     ((null bind) nil)
     ((hydra--callablep bind) (call-interactively bind)))))

This is how I add it to all my hydras:

(with-eval-after-load 'hydra
  (define-key hydra-base-map (kbd "<tab>") #'my-hydra-execute-extended))

Proooobably works? Very rough. Might be useful for those fuzzy-brain days.

Key chords

I'm on a Dvorak keyboard, so these might not work for you. Experimenting with this. key-chord lets you define keyboard shortcuts that use ordinary keys typed in quick succession. I haven't been using this lately, though…

Some code from

(defun my-key-chord-define (keymap keys command)
  "Define in KEYMAP, a key-chord of two keys in KEYS starting a COMMAND.
      \nKEYS can be a string or a vector of two elements. Currently only elements
      that corresponds to ascii codes in the range 32 to 126 can be used.
      \nCOMMAND can be an interactive function, a string, or nil.
      If COMMAND is nil, the key-chord is removed.

      MODIFICATION: Do not define the transposed key chord.
  (if (/= 2 (length keys))
      (error "Key-chord keys must have two elements"))
  ;; Exotic chars in a string are >255 but define-key wants 128..255 for those
  (let ((key1 (logand 255 (aref keys 0)))
        (key2 (logand 255 (aref keys 1))))
    (define-key keymap (vector 'key-chord key1 key2) command)))
(fset 'key-chord-define 'my-key-chord-define)

Now let's set up the actual keychords.

(use-package key-chord

  (key-chord-define-global "JJ" 'my-switch-to-previous-buffer)
  (key-chord-mode -1)) ;; disable for now

Hmm, good point about C-t being more useful as a Hydra than as transpose-char. It turns out I actually do use C-t a fair bit, but I can always add it back as an option.

Using Embark and qrencode to show a QR code for the Org Mode link at point   emacs org

[2024-01-12 Fri]: Added some code to display the QR code on the right side.

John Kitchin includes little QR codes in his videos. I thought that was a neat touch that makes it easier for people to jump to a link while they're watching. I'd like to make it easier to show QR codes too. The following code lets me show a QR code for the Org link at point. Since many of my links use custom Org link types that aren't that useful for people to scan, the code reuses the link resolution code from so that I can get the regular https: link.

(defun my-org-link-qr (url)
  "Display a QR code for URL in a buffer."
  (let ((buf (save-window-excursion (qrencode--encode-to-buffer (my-org-stored-link-as-url url)))))
    (display-buffer-in-side-window buf '((side . right)))))

(use-package qrencode

Color theme

Set up a light-on-dark color scheme

I like light on dark because I find it to be more restful. The color-theme in ELPA was a little odd, though, so we define some advice to make it work. Some things still aren't quite right.

(defun my-setup-color-theme ()

(use-package modus-themes
  :quelpa (modus-themes :fetcher github :repo "protesilaos/modus-themes")
  :init (setq modus-themes-to-toggle '(modus-vivendi modus-operandi))
  :config (my-setup-color-theme))

I sometimes need to switch to a lighter background for screenshots. For that, I use modus-themes-operandi.

Making highlight-sexp follow modus-themes-toggle   elisp emacs

[2023-01-27 Fri] Prot just added a modus-themes-get-color-value function. Yay! Also, it turns out that I need to update the overlay in all the buffers.

I'm experimenting with using the highlight-sexp minor mode to highlight my current s-expression, since I sometimes get confused about what I'm modifying with smartparens. The highlight-sexp background colour is hardcoded in the variable hl-sexp-background-color, and will probably look terrible if you use a light background. I wanted it to adapt when I use modus-themes-toggle. Here's how that works:

(use-package highlight-sexp
  (highlight-sexp :repo "daimrod/highlight-sexp" :fetcher github :version original)
  :after modus-themes
  ((emacs-lisp-mode . highlight-sexp-mode)
   (modus-themes-after-load-theme . my-hl-sexp-update-all-overlays))
  (defun my-hl-sexp-update-overlay ()
    (when (overlayp hl-sexp-overlay)
         ,(modus-themes-get-color-value 'bg-inactive)))))
  (defun my-hl-sexp-update-all-overlays (&rest args)
    (dolist (buf (buffer-list))
      (with-current-buffer buf
        (when highlight-sexp-mode
  (advice-add 'hl-sexp-create-overlay :after 'my-hl-sexp-update-overlay))

This is what it looks like:

Highlight the active modeline using colours from modus-themes   emacs

I wanted to experiment with for colouring the mode line of the active window ever so slightly different to make it easier to see where the active window is. I usually have global-hl-line-mode turned on, so that highlight is another indicator, but let's see how this tweak feels. I modified the code so that it uses the theme colours from the currently-selected Modus themes, since I trust Prot's colour choices more than I trust mine. Thanks to Irreal for sharing Ignacio's comment!

Undo tree mode - visualize your undos and branches

People often struggle with the Emacs undo model, where there's really no concept of "redo" - you simply undo the undo.

This lets you use C-x u (undo-tree-visualize) to visually walk through the changes you've made, undo back to a certain point (or redo), and go down different branches.

(use-package undo-tree
  :diminish undo-tree-mode
    (setq undo-tree-visualizer-timestamps t)

    (setq undo-tree-visualizer-diff t)
    (setq undo-tree-history-directory-alist '(("." . "~/.config/emacs/backups/undo-tree")))))

Winner mode - undo and redo window configuration

winner-mode lets you use C-c <left> and C-c <right> to switch between window configurations. This is handy when something has popped up a buffer that you want to look at briefly before returning to whatever you were working on. When you're done, press C-c <left>.

Windmove - switching between windows

Windmove lets you move between windows with something more natural than cycling through C-x o (other-window). Windmove doesn't behave well with Org, so we need to use different keybindings.

Frequently-accessed files

Registers allow you to jump to a file or other location quickly. To jump to a register, use C-x r j followed by the letter of the register. Using registers for all these file shortcuts is probably a bit of a waste since I can easily define my own keymap, but since I rarely go beyond register A anyway. Also, I might as well add shortcuts for refiling.

Building a today-I-learned habit, and displaying the documentation for random Emacs commands   emacs

I'd like to build a habit of regularly learning one small thing each day in one of three domains: tech, life, and learning. My measurable output would probably be in the form of index cards, tweets, blog posts, and notes (in org-capture, Dropbox, or Evernote). I can get input from various sources like blog posts, videos, books, webpages, and so on.

A little bit of randomness might be useful for learning more about Emacs. Emacswiki has a random page function, but the chunks are often a little large or irrelevant. On the other hand, displaying a random command from the packages that I already have loaded into my Emacs - that might be a good way to discover interesting things.

I started by looking at apropos-command, which led me to apropos-internal, which is a C function that referred to obarray. Using obarray by itself didn't work (suspiciously few elements, so I often ended up looking at emms-related functions). I eventually found mapatoms, which seems to do a better job at listing an appreciable number of interactive functions. I filtered the list to include only documented functions that had not been marked as obsolete: 8,415 in my current Emacs, which should be plenty to go through. =)

(defun my-describe-random-interactive-function ()
  "Show the documentation for a random interactive function.
     Consider only documented, non-obsolete functions."
  (let (result)
     (lambda (s)
       (when (and (commandp s)
                  (documentation s t)
                  (null (get s 'byte-obsolete-info)))
         (setq result (cons s result)))))
    (describe-function (elt result (random (length result))))))

I've added this to a key-chord + hydra keymap as a repeatable function, so I can type hh to start my Hydra and then type r as many times as I want in order to show the documentation for a random interactive function. If you're curious about that, you can see the key-chord section of my config.

Anyway, today I learned more about obarray and mapatoms - they're not interactive functions, but they were handy for building this little bit of code. We'll see how it goes! =)

DONE Audio braindump workflow tweaks: Adding Org Mode hyperlinks to recordings based on keywords

[2023-12-24 Sun] Added a quick video!

Audio recording is handy for capturing thoughts as I wait, walk around, or do chores. But my wireless earbuds don't have a good mic, I rarely got back to reviewing the wall of text, and I don't trust speech recognition to catch all my words.

Here's a new brain-dumping workflow that I've been experimenting with, though. I use a lapel mic to record in my phone. Google Recorder gives me an audio file as well as a rough transcript right away.


I copy those with Syncthing.

If I use keywords like "start" or "stop" along with things like "topic", "reminder", or "summary", then I can put those on separate lines automatically (my-audio-braindump-prepare-alignment-breaks).

News. Miscellaneous little tasks that he doing. I do want to
finish that blog post about the playlist Just so that it's out.
Something else that people can, you know, refer to or that I can refer
to. Uh, And at some point I want to think about, This second brain
So, right now, What's my current state? Uh,
Right now, I dumped everything into originally. In my inbox, if I come
across an interesting website. As usually in my phone. So then I share
it. As. Something links at those or four none. Uh, into my inbox.

I use subed-align to get the timestamps, and add the headings.

00:20:18.680 --> 00:20:24.679
So, right now, What's my current state? Uh,

NOTE CHAPTER: second brain

00:20:24.680 --> 00:20:30.719

I can then create an Org Mode TODO item with a quick hyperlinked summary as well as my transcript.

Figure 6: Summary with headings and links

I can jump to the audio if there are misrecognized words.

Figure 7: Following the link to the chapter in the VTT file

I can use subed-waveform to tweak the start and end times. (subed-waveform-show-current, then left-clicking to set the start or right-clicking to set the end, or using keybindings to adjust the start/stop).

Someday I'll write code to send sections to a better speech recognition engine or to AI. In the meantime, this is pretty good.

Here's how the code works:

Recognizing keyword phrases

There are several things I want to do while dictating.

  • I want to mark different topics so that it's easy to find the section where I was talking about something.
  • I might want to set tags or priorities, or even schedule something (today, tomorrow, next week, next month).
  • I can also use commands to trigger different things, like sending the section to a better speech recognition engine.

By analyzing the text, I might be able to make my own command system.

So far, for starting keywords, I can use "start", "begin", or "open". I pair that with one of these part keywords:

  • "section", "chapter", "topic", "summary": I use these pretty interchangeably at the moment. I want them to make a new Org heading.
  • "next steps": could be handy for being able to quickly see what to do next
  • "reminder":
  • "interruption": don't know what I'll use this for yet, but it might be useful to note this.
  • "tag", "keyword": maybe use this to add tags to the current section?

Then the code can extract the text until the matching "stop/close/end <part>", assuming it happens within 50 words or so. (my-audio-braindump-close-keyword-distance-words)

Sometimes keywords get misrecognized. "Begin summary" sometimes becomes "again summary" or "the game summary". I could try "open" and "close". Commercial dictation programs like Dragon NaturallySpeaking use "open" and "close" for punctuation, so that would probably work fine. "Start" works well, but "end" doesn't because it can confused with "and".

Sometimes an extra word sneaks in, either because I say it or because the speech recognition tries too hard to guess. "Begin reminder" ends up as "Begin a reminder." I changed from using regular expressions that searched for just start-keyword + part-keyword to one that looked for the start of the keyword phrase and then looked for the next keyword within the next X words. (my-audio-braindump-scan-for-part-keyword)

(defvar my-audio-braindump-open-keywords '("start" "begin" "open"))
(defvar my-audio-braindump-close-keywords '("stop" "end" "close"))
(defvar my-audio-braindump-part-keywords '("summary" "chapter" "topic"
                                 "action" "idea" "journal" "reminder"
                                 "command" "interruption" "note"
                                 "next step" "next steps" "tags" "tag" "keywords" "keyword"))

  (setq before-part (pcase before-part
                      ('start my-audio-braindump-open-keywords)
                      ('stop my-audio-braindump-close-keywords)

          (setq result (list start (match-end 0) before-word (match-string 0)))))
      (when result (goto-char (elt result 1)))

      (expect (elt result 2) :to-equal "stop")
      (expect (elt result 3) :to-equal "reminder"))))

Splitting the lines based on keywords and oopses

Now I can use that to scan through the text. I want to put commands on their own lines so that subed-align will get the timestamp for that segment and so that the commands are easier to parse.

I also want to detect "oops" and split things up so that the start of that line matches my correction after the "oops". I use my-subed-split-oops for that, which I should write about in another post. By putting the oops fragment on its own line, I can use subed-align to get a timestamp for just that segment. Then I can either use flush-lines to get rid of anything with "oops" in it. I can even remove the subtitle and use subed-record-compile-media to compile audio/video without that segment, if I want to use the audio without rerecording it.

And the way I can help is by jotting words down in a mind map,
typing her sentences. Oops
typing, her sentences And generating, follow-up questions.

I also all-caps the keyword phrases so that they're easier to see when skimming the text file.

(defun my-audio-braindump-prepare-alignment-breaks ()
  "Split lines in preparation for forced alignment with aeneas.

    (while (setq result (my-audio-braindump-scan-for-part-keyword 'start nil nil t))
      (goto-char (car result))
      (delete-region (car result) (elt result 1))

Preparing the VTT subtitles

subed-align gives me a VTT subtitle file with timestamps and text. I add NOTE comments with the keywords and make subed: links to the timestamps using the ol-subed.el that I just added.

(defun my-audio-braindump-get-subtitle-note-based-on-keywords (sub-text)
  (let ((case-fold-search t))
    (when (string-match (concat "^"
                                (regexp-opt my-audio-braindump-open-keywords)
                                " \\(" (regexp-opt my-audio-braindump-part-keywords) "\\) \\(.+?\\)\\( "
                                (regexp-opt my-audio-braindump-close-keywords) " "
                                (regexp-opt my-audio-braindump-part-keywords) "\\)?$")
      (concat (match-string 1 sub-text) ": " (match-string 2 sub-text)))))
(ert-deftest my-audio-braindump-get-subtitle-note-based-on-keywords ()
  (expect (my-audio-braindump-get-subtitle-note-based-on-keywords "BEGIN NEXT STEPS . Think about how dictation helps me practice slower speed. CLOSE NEXT STEPS")
          :to-equal "NEXT STEPS: . Think about how dictation helps me practice slower speed.")
  (expect (my-audio-braindump-get-subtitle-note-based-on-keywords "START SUMMARY hello world STOP SUMMARY")
          :to-equal "SUMMARY: hello world")
  (expect (my-audio-braindump-get-subtitle-note-based-on-keywords "START CHAPTER hello world again")
          :to-equal "CHAPTER: hello world again")

Process a single transcript from the raw text file

So now we put that all together: rename the file using the calculated start time, prepare the alignment breaks, align the file to get the timestamps, and add the subtree to an Org file.

Process multiple files

I want to process multiple files in one batch.

It would be nice to have it automatically keep track of the latest one that's been processed, maybe via customize-save-variable. This still needs some tinkering with.

Ideas for next steps

  • Make the commands process things even more automatically.
  • Experiment with just sending everything to OpenAI Whisper instead of conditionally sending it based on the keywords (which might not be recognized).
  • See if I want to reuse more sentences or move them around.
  • Find out where people who have thought about dictation keywords have their notes; probably don't have to reinvent the wheel here

Unfill paragraph

I unfill paragraphs a lot because Wordpress likes adding extra <br> tags if I don't. (I should probably just tweak my Wordpress installation.)

(defun my-unfill-paragraph (&optional region)
  "Takes a multi-line paragraph and makes it into a single line of text."
  (interactive (progn
                 (list t)))
  (let ((fill-column (point-max)))
    (fill-paragraph nil region)))
(bind-key "M-Q" 'my-unfill-paragraph)

I never actually justify text, so I might as well change the way fill-paragraph works. With the code below, M-q will fill the paragraph normally, and C-u M-q will unfill it.

(defun my-fill-or-unfill-paragraph (&optional unfill region)
  "Fill paragraph (or REGION).
        With the prefix argument UNFILL, unfill it instead."
  (interactive (progn
                 (list (if current-prefix-arg 'unfill) t)))
  (let ((fill-column (if unfill (point-max) fill-column)))
    (fill-paragraph nil region)))
(bind-key "M-q" 'my-fill-or-unfill-paragraph)

Also, visual-line-mode is so much better than auto-fill-mode. It doesn't actually break the text into multiple lines - it only looks that way.

Using Emacs to fix automatically generated subtitle timestamps   emacs

I like how people are making more and more Emacs-related videos. I think subtitles, transcripts, and show notes would go a long way to helping people quickly search, skim, and squeeze these videos into their day.

Youtube's automatically-generated subtitles overlap. I think some players scroll the subtitles, but the ones I use just display them in alternating positions. I like to have non-overlapping subtitles, so here's some code that works with subed.el to fix the timestamps.

(defun my-subed-fix-timestamps ()
  "Change all ending timestamps to the start of the next subtitle."
  (goto-char (point-max))
  (let ((timestamp (subed-subtitle-msecs-start)))
    (while (subed-backward-subtitle-time-start)
      (subed-set-subtitle-time-stop timestamp)
      (setq timestamp (subed-subtitle-msecs-start)))))

Then it's easy to edit the subtitles (punctuation, capitalization, special terms), especially with the shortcuts for splitting and merging subtitles.

For transcripts with starting and ending timestamps per paragraph, I like using the merge shortcut to merge all the subtitles for a paragraph together. Here's a sample:

Tonight I edited automatically-generated subtitles for a screencast that was about 40 minutes long. The resulting file had 1157 captions, so about 2 seconds each. I finished it in about 80 minutes, pretty much the 2x speed that I've been seeing. I can probably get a little faster if I figure out good workflows for:

  • jumping: avy muscle memory, maybe?
  • splitting things into sentences and phrases
  • fixing common speech recognition errors (ex: emax -> Emacs, which I handle with regex replaces; maybe a list of them?)

    I experimented with making a hydra for this before, but thinking about the keys to use slowed me down a bit and it didn't flow very well. Might be worth tinkering with.

    Transcribing from scratch takes me about 4-5x playtime. I haven't tweaked out my workflow for that one yet because I've only transcribed one talk with subed.el , and there's a pretty big backlog of talks that already have automatically generated subtitles to edit.

    So that's another thing I (or other people) can occasionally do to help out even if I don't have enough focused time to think about a programming challenge or do a podcast myself. And I get to learn more in the process, too. Fun!

Using word-level timing information when editing subtitles or captions in Emacs   emacs

2022-10-26: Merged word-level timing support into subed.el, so I don't need my old caption functions.

2022-04-18: Switched to using yt-dlp.

I like to split captions at logical points, such as at the end of a phrase or sentence. At first, I used subed.el to play the video for the caption, pausing it at the appropriate point and then calling subed-split-subtitle to split at the playback position. Then I modified subed-split-subtitle to split at the video position that's proportional to the text position, so that it's roughly in the right spot even if I'm not currently listening. That got me most of the way to being able to quickly edit subtitles.

It turns out that word-level timing is actually available from YouTube if I download the autogenerated SRV2 file using yt-dlp, which I can do with the following function:

(defun my-caption-download-srv2 (id)
  (interactive "MID: ")
  (require 'subed-word-data)
  (when (string-match "v=\\([^&]+\\)" id) (setq id (match-string 1 id)))
  (let ((default-directory "/tmp"))
    (call-process "yt-dlp" nil nil nil "--write-auto-sub" "--write-sub" "--no-warnings" "--sub-lang" "en" "--skip-download" "--sub-format" "srv2"
                  (concat "" id))
    (subed-word-data-load-from-file (my-latest-file "/tmp" "\\.srv2\\'"))))

2022-10-26: I can also generate a SRV2-ish file using torchaudio, which I can then load with subed-word-data-load-from-file.

(defun my-caption-fix-common-errors (data)
  (mapc (lambda (o)
          (mapc (lambda (e)
                  (when (string-match (concat "\\<" (regexp-opt (if (listp e) (seq-remove (lambda (s) (string= "" s)) e)
                                                                  (list e)))
                                      (alist-get 'text o))
                    (map-put! o 'text (replace-match (car (if (listp e) e (list e))) t t (alist-get 'text o)))))

Assuming I start editing from the beginning of the file, then the part of the captions file after point is mostly unedited. That means I can match the remainder of the current caption with the word-level timing to try to figure out the time to use when splitting the subtitle, falling back to the proportional method if the data is not available.

(defun subed-avy-set-up-actions ()
  (make-local-variable 'avy-dispatch-alist)
   (cons ?, 'subed-split-subtitle)))

(use-package subed

  (with-eval-after-load 'consult
    (advice-add 'consult-buffer :around
                (lambda (f &rest r)
                  (let ((subed-auto-play-media nil))
                    (apply f r)))))


That way, I can use the word-level timing information for most of the reformatting, but I can easily replay segments of the video if I'm unsure about a word that needs to be changed.

If I want to generate a VTT based on the caption data, breaking it at certain words, these functions help:

        (current-length 0)
        (limit (or threshold 70))
        (lower-limit 30)
        (break-regexp (concat "\\<" (regexp-opt my-caption-breaks) "\\>")))
    (while list
       ((null (car list)))
       ((string-match "^\n*$" (alist-get 'text (car list)))
        (push (cons '(text . " ") (car list)) current-item)
        (setq current-length (1+ current-length)))

        (setq current-item (cons (car list) current-item)
              current-length (+ current-length (length (alist-get 'text (car list))) 1)))
       (t (setq done nil)
          (while (not done)
           ((< current-length lower-limit)
            (setq done t))
           ((and (string-match break-regexp (alist-get 'text (car current-item)))
                 (not (string-match break-regexp (alist-get 'text (cadr current-item)))))
            (setq current-length (- current-length (length (alist-get 'text (car current-item)))))
            (push (pop current-item) list)
            (setq done t))
            (setq current-length (- current-length (length (alist-get 'text (car current-item)))))
            (push (pop current-item) list))))

TODO Org Mode: Insert YouTube video with separate captions   emacs

I'm playing around with some ideas for making it easier to post a video with its captions on a webpage or in an Org file so that it's easier to skim or search.

This requires the yt-dlp command. I'm also learning how to use dash.el's threading macro, so you'll need to install that as well if you want to run it.

It makes an embedded Youtube video and a table with captions below it. The Org file doesn't look too bad, either.


I decided to stick to standard Org syntax so that I can read it in Emacs too. With the current implementation, clicking on the timestamps jumps to that position in the video, but on the Youtube website. I haven't coded anything fancy like keeping the embedded video at a fixed position, controlling it from the clicks, or highlighting the current position. It's a start, though!

Here's the output of running it with my talk from the last EmacsConf.

00:00:00.000 I'm Sacha Chua, and welcome to EmacsConf 2020.

00:00:11.000 or if you'd like to add something I've missed,
00:00:14.000 add them to the collaborative pad

Speech recognition

TOBLOG Using Emacs Lisp to send audio files to Deepgram and format VTTs   emacs speech

I've been experimenting with Deepgram's API for speech recognition because it can handle larger files than OpenAI Whisper's API, so I don't have to worry about chunking my files into 15-minute segments. It also supports diarization, which means identifying different speakers. That's handy for things like the EmacsConf Q&A sessions, which involve multiple people.

I think the built-in VTT formatter doesn't handle speaker identification, so I wrote some Emacs Lisp to send an audio file for recognition, save the JSON, and format the results as a VTT subtitle file. I also split the captions a little closer to the way I like to do them, starting a new subtitle if the line exceeds my-deepgram-length-threshold or my-deepgram-time-threshold, or if we're after a punctuated word and the current subtitle is more than halfway to the length threshold. Someday I'll figure out how to get it to split on prepositions.

(defvar my-deepgram-length-threshold 45 "Number of characters.")
(defvar my-deepgram-time-threshold 10 "Number of seconds since the first word.")

DONE Getting live speech into Emacs with Deepgram's streaming API   emacs speech

  • [2023-12-26 Tue]: Reorganized code to call a list of functions and pass the recognition results. Added Etherpad. Took out the mode; will just use the functions. Related:

This is a quick demonstration of using Deepgram's streaming API to do speech recognition live. It isn't as accurate as OpenAI Whisper but since Whisper doesn't have a streaming API, it'll do for now. I can correct misrecognized words manually. I tend to talk really quickly, so it displays the words per minute in my modeline. I put the words into an Org Mode buffer so I can toggle headings with avy and cycle visibility. When I'm done, it saves the text, JSON, and WAV for further processing. I think it'll be handy to have a quick way to take live notes during interviews or when I'm thinking out loud. Could be fun!

I'm still getting some weirdness when the mode turns on when I don't expect it, so that's something to look into. Maybe I won't use it as a mode for now. I'll just use my-live-speech-start and my-live-speech-stop.

The Python script sends the microphone stream to Deepgram and prints out the JSON output. The Emacs Lisp code starts an asynchronous process and reads the JSON output, displaying the transcript and calculating the WPM based on the words. just loads the venv for this project (requirements.txt based on the streaming text suite) and then runs, since some of the Python library versions conflict with other things I want to experiment with.

I also added my-live-speech-wpm-string to my mode-line-format manually using Customize, since I wanted it displayed on the left side instead of getting lost when I turn keycast-mode on.

I'm still a little anxious about accidentally leaving a process running, so I check with ps aux | grep python3. Eventually I'll figure out how to make sure everything gets properly stopped when I'm done.

Anyway, there it is!

Org navigation

Viewing, navigating, and editing the Org tree

I often cut and paste subtrees. This makes it easier to cut something and paste it elsewhere in the hierarchy.

  (setq org-yank-adjusted-subtrees t))

Finding my place on a small mobile screen with org-back-to-heading

There's probably a better way to do this. I'm surprised org-back-to-heading isn't interactive yet. It's useful.

(defun my-org-back-to-heading ()

(use-package org
  :bind (:map org-mode-map

Dealing with big tables

Sometimes I forget where I am in a big table. This would be nice to turn into a minor mode someday.

(defun my-org-show-row-and-column (point)
  (interactive "d")
    (goto-char point)
    (let ((row (s-trim (org-table-get nil 1)))
          (col (s-trim (org-table-get 1 nil)))
          (message-log-max nil))
      (message "%s - %s" row col))))

Taking notes

(setq org-directory "~/sync/orgzly/")
(setq org-default-notes-file "~/sync/orgzly/")

Date trees

This quickly adds a same-level heading for the succeeding day.

(defun my-org-insert-heading-for-next-day ()
  "Insert a same-level heading for the following day."
  (let ((new-date
          (+ 86400.0
              (org-read-date nil 'to-time (elt (org-heading-components) 4)))))))
    (insert (format-time-string "%Y-%m-%d\n\n" new-date))))


I use org-capture templates to quickly jot down tasks, ledger entries, notes, and other semi-structured pieces of information.

        (message "WPM: %d (words: %d, minutes: %d)" wpm words minutes)
        (kill-new (number-to-string wpm))))))

    (insert note)


Managing tasks

Track TODO state

The parentheses indicate keyboard shortcuts that I can use to set the task state. @ and ! toggle logging. @ prompts you for a note, and ! automatically logs the timestamp of the state change.

(setq org-todo-keywords
         "TODO(t)"  ; next action
         "TOBLOG(b)"  ; next action
         "SOMEDAY(.)" "BLOCKED(k@/!)" "|" "DONE(x!)" "CANCELLED(c)")
        (sequence "PROJECT" "|" "DONE(x)")
        (sequence "LEARN" "TRY" "TEACH" "|" "COMPLETE(x)")
        (sequence "TOSKETCH" "SKETCHED" "|" "POSTED")
        (sequence "TOBUY" "TOSHRINK" "TOCUT"  "TOSEW" "|" "DONE(x)")
        (sequence "TODELEGATE(-)" "DELEGATED(d)" "|" "COMPLETE(x)")))
(setq org-todo-keyword-faces
      '(("TODO" . (:foreground "green" :weight bold))
        ("DONE" . (:foreground "cyan" :weight bold))
        ("WAITING" . (:foreground "red" :weight bold))
        ("SOMEDAY" . (:foreground "gray" :weight bold))))
(setq org-log-done 'time)

Projects are headings with the :project: tag, so we generally don't want that tag inherited, except when we display unscheduled tasks that don't belong to any projects.

(setq org-tags-exclude-from-inheritance '("project"))

This code makes it easy for me to focus on one project and its tasks.

(with-eval-after-load 'org
  (let ((listvar (if (boundp 'org-speed-commands) 'org-speed-commands
    (add-to-list listvar '("N" org-narrow-to-subtree))
    (add-to-list listvar '("W" widen))
    (add-to-list listvar '("T" my-org-agenda-for-subtree))
    (add-to-list listvar '("b" my-org-bounce-to-file))))

(defun my-org-agenda-for-subtree ()
  (when (derived-mode-p 'org-agenda-mode) (org-agenda-switch-to))
   (let ((org-agenda-view-columns-initially t))
     (org-agenda nil "t" 'subtree))))

There's probably a proper way to do this, maybe with <. Oh, that would work nicely. < C-c a t too.

And sorting:

(with-eval-after-load 'org
  (let ((listvar (if (boundp 'org-speed-commands) 'org-speed-commands
    (add-to-list listvar '("S" call-interactively 'org-sort))))
Tag tasks with GTD-ish contexts

This defines keyboard shortcuts for those, too.

(setq org-tag-alist '(("work" . ?b)
                      ("home" . ?h)
                      ("writing" . ?w)
                      ("errands" . ?e)
                      ("drawing" . ?d)
                      ("coding" . ?c)
                      ("video" . ?v)
                      ("kaizen" . ?k)
                      ("phone" . ?p)
                      ("learning" . ?a)
                      ("reading" . ?r)
                      ("computer" . ?l)
                      ("quantified" . ?q)
                      ("shopping" .?s)
                      ("focus" . ?f)))
Enable filtering by effort estimates

That way, it's easy to see short tasks that I can finish.

(add-to-list 'org-global-properties
             '("Effort_ALL". "0:05 0:15 0:30 1:00 2:00 3:00 4:00"))
Track time
(use-package org
    (setq org-expiry-inactive-timestamps t)
    (setq org-clock-idle-time nil)
    (setq org-log-done 'time)
    (setq org-clock-auto-clock-resolution nil)
    (setq org-clock-continuously nil)
    (setq org-clock-persist t)
    (setq org-clock-in-switch-to-state "STARTED")
    (setq org-clock-in-resume nil)
    (setq org-show-notification-handler 'message)
    (setq org-clock-report-include-clocking-task t))

Too many clock entries clutter up a heading.

(setq org-log-into-drawer "LOGBOOK")
(setq org-clock-into-drawer 1)

I like using org-habits to track consistency. My task names tend to be a bit long, though, so I've configured the graph column to show a little bit more to the right.

(setq org-habit-graph-column 80)
(setq org-habit-show-habits-only-for-today nil)

If you want to use habits, be sure to schedule your tasks and add a STYLE property with the value of habit to the tasks you want displayed.

Estimating tasks

From "Add an effort estimate on the fly when clocking in" on the Org Hacks page:

(add-hook 'org-clock-in-prepare-hook

(defun my-org-mode-ask-effort ()
  "Ask for an effort estimate when clocking in."
  (unless (org-entry-get (point) "Effort")
    (let ((effort
            "Effort: "
            (org-entry-get-multivalued-property (point) "Effort"))))
      (unless (equal effort "")
        (org-set-property "Effort" effort)))))

Flexible scheduling of tasks

I (theoretically) want to be able to schedule tasks for dates like the first Saturday of every month. Fortunately, someone else has figured that out!

;; Get this from
(load "~/elisp/next-spec-day.el" t)

Quick way to archive all DONE from inbox   emacs computer

    (if (org-at-heading-p) (save-excursion (insert "\n")))
    (org-sort-entries nil ?p)
    (goto-char (point-min))
    (org-sort-entries nil ?o)

(defun my-org-archive-done-tasks (&optional scope)
  "Archive finished or cancelled tasks.

   (lambda ()
     (setq org-map-continue-from (outline-previous-heading)))
   "TODO=\"DONE\"|TODO=\"CANCELLED\"" (or scope (if (org-before-first-heading-p) 'file 'tree))))

Strike through DONE headlines

I wanted a quick way to visually distinguish DONE tasks from tasks I still need to do. This handy snippet from the Emacs Org-mode mailing list does the trick by striking through the headlines for DONE tasks.

(setq org-fontify-done-headline t)
 '(org-done ((t (:foreground "PaleGreen"
                             :weight normal
                             :strike-through t))))
   ((((class color) (min-colors 16) (background dark))
     (:foreground "LightSalmon" :strike-through t)))))


Structure templates

Org makes it easy to insert blocks by typing <s[TAB], etc. I hardly ever use LaTeX, but I insert a lot of Emacs Lisp blocks, so I redefine <l to insert a Lisp block instead.

(setq org-structure-template-alist
      '(("a" . "export ascii")
        ("C" . "center")
        ("c" . "comment")
        ("d" . "my_details")
        ("e" . "example")
        ("E" . "export")
        ("m" . "export md")
        ("h" . "export html")
        ("j" . "src js :spookfox t")
        ("l" . "src emacs-lisp")
        ("p" . "src python")
        ("n" . "notes")
        ("q" . "quote")
        ("s" . "src")
        ("S" . "src sh")
        ("u" . "update")
        ("v" . "verse")))

This lets me nest quotes.

(defun my-org-html-quote2 (block backend info)
  (when (org-export-derived-backend-p backend 'html)
    (when (string-match "\\`<div class=\"quote2\">" block)
      (setq block (replace-match "<blockquote>" t nil block))
      (string-match "</div>\n\\'" block)
      (setq block (replace-match "</blockquote>\n" t nil block))
(eval-after-load 'ox
  '(add-to-list 'org-export-filter-special-block-functions 'my-org-html-quote2))

Org agenda

Basic configuration

I have quite a few Org files, but I keep my agenda items and TODOs in only a few of them them for faster scanning.

(defvar my-kid-org-file nil "Defined in secrets")
(setq org-agenda-files
      (delq nil
            (mapcar (lambda (x) (and x (file-exists-p x) x))
(setq org-agenda-dim-blocked-tasks nil)
(add-to-list 'auto-mode-alist '("\\.txt$" . org-mode))

I like looking at two days at a time when I plan using the Org agenda. I want to see my log entries, but I don't want to see scheduled items that I've finished. I like seeing a time grid so that I can get a sense of how appointments are spread out.

(setq org-agenda-span 2)
(setq org-agenda-tags-column -100) ; take advantage of the screen width
(setq org-agenda-sticky nil)
(setq org-agenda-inhibit-startup t)
(setq org-agenda-use-tag-inheritance t)
(setq org-agenda-show-log t)
(setq org-agenda-skip-scheduled-if-done t)
(setq org-agenda-skip-deadline-if-done t)
(setq org-agenda-skip-deadline-prewarning-if-scheduled 'pre-scheduled)
(setq org-agenda-time-grid
      '((daily today require-timed)
        (800 1000 1200 1400 1600 1800 2000)
        "......" "----------------"))
(setq org-columns-default-format "%14SCHEDULED %Effort{:} %1PRIORITY %TODO %50ITEM %TAGS")

Some other keyboard shortcuts:

(bind-key "Y" 'org-agenda-todo-yesterday org-agenda-mode-map)

Starting my weeks on Saturday

I like looking at weekends as week beginnings instead, so I want the Org agenda to start on Saturdays.

(setq org-agenda-start-on-weekday 6)

Display projects with associated subtasks

I wanted a view that showed projects with a few subtasks underneath them. Here's a sample of the output:

Org agenda custom commands

There are quite a few custom commands here, and I often forget to use them. =) But it's good to define them, and over time, I'll get the hang of using these more!

Key Description
. What am I waiting for?
T Not really an agenda command - shows the to-do tree in the current file
b Shows business-related tasks
o Shows personal tasks and miscellaneous tasks (o: organizer)
w Show all tasks for the upcoming week
W Show all tasks for the upcoming week, aside from the routine ones
g … Show tasks by context: b - business; c - coding; w - writing; p - phone; d - drawing, h - home
0 Show common contexts with up to 3 tasks each, so that I can choose what I feel like working on
) (shift-0) Show common contexts with all the tasks associated with them
9 Show common contexts with up to 3 unscheduled tasks each
( (shift-9) Show common contexts with all the unscheduled tasks associated with them
d Timeline for today (agenda, clock summary)
u Unscheduled tasks to do if I have free time
U Unscheduled tasks that are not part of projects
P Tasks by priority
p My projects
2 Projects with tasks

Monthly reviews

I want to be able to see what I worked on in a month so that I can write my monthly reviews. This code makes it easy to display a month's clocked tasks and time. I haven't been particularly thorough in tracking time before, but now that I have a shortcut that logs in Quantified Awesome as well as in Org, I should end up clocking more.

(defun my-org-review-month (start-date)
  "Review the month's clocked tasks and time."

  (setq start-date (concat (substring start-date 0 8) "01"))

DONE Automatically refiling Org Mode headings based on tags   org emacs

I have lots of different things in my Org Mode inbox. Following the PARA method, I want to file them under projects, areas, resources, or archive so that I can find related things later. Actually, no, I don't want to refile them. I do want to be able to:

  • find all the pieces related to something when I'm ready to start working on a task
  • find useful links again, especially if I can use my own words

Refiling is annoying on my phone, so I tend to wait until I'm back at my computer. But even with org-refile-use-outline-path set to file and the ability to specify substrings, there's still a bit of friction.

Tagging is a little easier to do on my phone. I can add a few tags when I share a webpage or create a task.

I thought it would be nice to have something that automatically refiles my inbox headings tagged with various tags to other subtrees where I've set a :TAG_TARGET: property or something like that. For example, I can set the TAG_TARGET property to emacsconf to mean that anything tagged with :emacsconf: should get filed under there.

So when I'm ready, I can call my-org-refile-to-tag-targets and have lots of things disappear from my inbox.

Next step might be to write a function that will refile just the current subtree (either going straight to the tag target or prompting me for a destination if there isn't a matching one), so I can look at stuff, decide if it needs to be scheduled first or something like that, and then send it somewhere. There must be something I can pass a property match to and it'll tell me if it matches the current subtree - probably something along the lines of org-make-tags-matcher

Anyway, just wanted to share this!

Refiling Org Mode notes to headings in the same file   org emacs

I spent some time tidying up my Emacs configuration . I used org-babel-demarcate-block to split up some long #+begin_src...#+end_src blocks and refiled sections to group them together. I also promoted more sections to top-level headings in order to make the most of the side navigation provided by the Read the Org setup file based on Read the Docs. These functions were helpful:

(defun my-org-refile-in-file (&optional prefix)
  "Refile to a target within the current file."
  (let ((org-refile-targets (list (cons nil '(:maxlevel . 5)))))
    (call-interactively 'org-refile)))

(defun my-org-refile-to-previous ()
  "Refile subtree to last position from `my-org-refile-in-file'."
    (when (eq major-mode 'org-agenda-mode)
        (bookmark-jump (plist-get org-bookmark-names-plist :last-refile))
        (let ((level (org-current-level)))
          (org-end-of-subtree t t)

(with-eval-after-load 'org
  (push '("w" call-interactively 'org-refile) org-speed-commands)
  (push '("W" call-interactively 'my-org-refile-in-file) org-speed-commands)
  (push '("." call-interactively 'my-org-refile-to-previous) org-speed-commands))

I usually have org-refile-targets set to a long list of files so that I can use C-u C-c C-w to jump to headings from anywhere, but I just wanted to refile other things in my configuration, so it was nice to limit the scope to just that file.

I like using org-speed-commands to give me quick shortcuts when I'm at headings.

Org Mode: Including portions of files between two regular expressions   org emacs

  • 2023-10-11 Wed: Include images inline.
  • 2023-09-10: Use consult-line instead of consult--line.

I'd like to refer to snippets of code, but lines are too fragile to use as references for code and posts that I want to easily update. I'd like to specify a from-regexp and a to-regexp instead in order to collect the lines between those regexps (including the ones with the regexps themselves). org-export-expand-include-keyword looked a bit hairy to extend since it uses regular expressions to match parameter values. For this quick experiment, I decided to make a custom link type instead. This allows me to refer to parts of code with a link like this:

[[my-include:~/proj/static-blog/assets/css/style.css::from-regexp=Start of copy code&to-regexp=End of copy code&wrap=src js]]

which will turn into this snippet from my stylesheet:

Here's the Emacs Lisp code to do that. my-include-complete function reuses my-include-open to narrow to the file, and my-include-complete uses consult-line so that we can specify the prompt.

 :export #'my-include-export

Org Mode: Create a quick timestamped note and capture a screenshot   emacs org

I wanted to be able to quickly create timestamped notes and possibly capture a screenshot. Prompting for a value inside an org-capture-template disrupts my screen a little, so maybe this will make it as easy as possible. I could probably do this without going through org-capture-templates, but I wanted to take advantage of the fact that Org Mode will deal with the date tree and finding the right position itself.

Moving my Org post subtree to the 11ty directory   11ty org emacs blogging

I sometimes want to move the Org source for my blog posts to the same directory as the 11ty-exported HTML. This should make it easier to update and reexport blog posts in the future. The following code copies or moves the subtree to the 11ty export directory.

(defun my-org-11ty-copy-subtree (&optional do-cut)
  "Copy the subtree for the current post to the 11ty export directory.
With prefix arg, move the subtree."
  (interactive (list current-prefix-arg))
  (let* ((file-properties
              (goto-char (point-min))
              (cl-loop while (re-search-forward "^#\\+ELEVENTY.*" nil t)
                       collect (match-string 0)))))
         (entry-properties (org-entry-properties))
         (filename (expand-file-name
                     (assoc-default "EXPORT_ELEVENTY_FILE_NAME" entry-properties)
                     (car (assoc-default "ELEVENTY_BASE_DIR" file-properties))))))
    (unless (file-directory-p (file-name-directory filename))
      (make-directory (file-name-directory filename) t))
    ;; find the heading that sets the current EXPORT_ELEVENTY_FILE_NAME
     (org-find-property "EXPORT_ELEVENTY_FILE_NAME" (org-entry-get-with-inheritance "EXPORT_ELEVENTY_FILE_NAME")))
    (org-copy-subtree 1 (if do-cut 'cut))
    (with-temp-file filename
      (insert (or
               (string-join file-properties
    ;(find-file filename)
    ;(goto-char (point-min))

Then this adds a link to it:

(defun my-org-export-filter-body-add-index-link (info)
  (when (and
         (plist-get info :file-name)
         (plist-get info :base-dir)
         (file-exists-p (expand-file-name
                          (plist-get info :file-name)
                          (plist-get info :base-dir)))))
    (goto-char (point-max))
     (format "<div><a href=\"\">View org source for this post</a></div>"
             (plist-get info :permalink)))))

(with-eval-after-load 'ox-11ty
  (add-to-list 'org-11ty-process-export-functions #'my-org-export-filter-body-add-index-link))

Then I want to wrap the whole thing up in an export function:

(defun my-org-11ty-export (&optional async subtreep visible-only body-only ext-plist)
  (let* ((info (org-11ty--get-info subtreep visible-only))
         (file (org-11ty--base-file-name subtreep visible-only)))
    (unless (string= (plist-get info :input-file)
                       (plist-get info :file-name)
                       (plist-get info :base-dir))))
    (org-11ty-export-to-11tydata-and-html async subtreep visible-only body-only ext-plist)

Now to figure out how to override the export menu. Totally messy hack!

(with-eval-after-load 'ox-11ty
  (map-put (caddr (org-export-backend-menu (org-export-get-backend '11ty)))
           ?1 (list "To Org, 11tydata.json, HTML" 'my-org-11ty-export)))

Cleaning up export

Timestamps and section numbers make my published files look more complicated than they are. Let's turn them off by default, and let's use fancy HTML5.

(setq org-html-doctype "html5")
(setq org-html-html5-fancy t)
(setq org-export-with-section-numbers nil)
(setq org-html-include-timestamps nil)
(setq org-export-with-sub-superscripts nil)
(setq org-export-with-toc nil)
(setq org-html-toplevel-hlevel 2)
(setq org-export-htmlize-output-type 'css)
(setq org-export-with-broken-links t)
(setq org-ascii-text-width 10000)
(setq-default tab-width 2)

This makes it easier to publish my files:

(setq org-publish-project-alist
         :base-directory "~/proj/stream"
         :base-directory "~/.config/emacs"
         :publishing-directory "~/.config/emacs"
         :publishing-function my-org-html-publish-to-html-trustingly
         :base-directory "c:/sacha/Dropbox/books"
         :publishing-directory "c:/sacha/Dropbox/books/html"
         :publishing-function my-org-html-publish-to-html-trustingly
         :makeindex t)))
;(load "~/proj/dev/emacs-chats/build-site.el" t)
;(load "~/proj/dev/emacs-notes/build-site.el" t)

If a file is in a publishing project, publish it.

(defun my-org-publish-maybe ()
  (require 'ox-publish)
    (if (org-publish-get-project-from-filename
         (buffer-file-name (buffer-base-buffer)) 'up)
        (org-publish-current-file t)

Make it easy to publish and browse a file.

(defun my-org-publish-and-browse ()
  (browse-url (org-export-output-file-name ".html" nil default-directory)))
(bind-key "<apps> b" 'my-org-publish-and-browse)

Publish without prompting

I want to be able to export without having to say yes to code blocks all the time.

(defun my-org-html-export-trustingly ()
  (let ((org-confirm-babel-evaluate nil))

(defun my-org-html-publish-to-html-trustingly (plist filename pub-dir)
  (let ((org-confirm-babel-evaluate nil))
    (org-html-publish-to-html plist filename pub-dir)))

                 title-color title contents))))

  (org-defblock columns nil nil

Adding a custom header argument to Org Mode source blocks and using that argument during export   org emacs

I sometimes want to put long source blocks in a <details><summary>...</summary>...</details> block when I export to HTML, so that they're tucked away in a collapsible block. I tried using to define my own #+begin_my_details "summary text" ... #+end_my_details block, but source blocks inside my_details doesn't get fontlocked properly while in the Org file. I wanted to add a :summary attribute to the regular src blocks, and to change the HTML export to wrap the code in details if the summary was specified.

So now I can use it by specifying blocks like this:

#+begin_src emacs-lisp :summary "Code for adding a :summary argument and using it during export"
;; code goes here

It took me a bit of digging around to figure this out. When I added the :summary attribute, org-babel-get-src-block-info found it when I was in the Org file, but by the time my-org-html-src-block was called, the block had been replaced with a copy that didn't have the header argument. I dug around using edebug's d command for displaying the backtrace, stepping through various functions. I found out that in the process for exporting source code blocks, org-babel-exp-code replaces the source block with the value of org-babel-exp-code-template, substituting certain values. Adding the summary flag to that and retrieving the summary information using org-babel-get-src-block-info worked. I originally used advice-add to override org-html-src-block, but I think I'll try replacing the transcoder.

Adding custom header arguments could be useful for different export-related tweaks (someone wanted to create an argument for highlighting certain lines but hadn't figured it out in that thread). If there's a more elegant way to do this, I'd love to find out!

Stylesheet / header

Might as well take advantage of my stylesheet:

(setq org-html-head "
       <link rel=\"stylesheet\" type=\"text/css\" href=\"\"></link>
       <link rel=\"stylesheet\" type=\"text/css\" href=\"\"></link>
       <script src=\"\"></script>
       <script src=\"\"></script>")
(setq org-html-htmlize-output-type 'css)
(setq org-src-fontify-natively t)

Copy region

Sometimes I want a region's HTML in my kill-ring/clipboard without any of the extra fluff:

(defun my-org-copy-region-as-html (beg end &optional level)
  "Make it easier to copy code for Wordpress posts and other things."
  (interactive "r\np")
  (let ((org-export-html-preamble nil)
        (org-html-toplevel-hlevel (or level 3)))
     (org-export-string-as (buffer-substring beg end) 'html t))))

Sometimes I want a subtree:

(defun my-org-copy-subtree-as-html ()

UTF-8 checkboxes

This snippet turns - [X] into ☑ and - [ ] into ☐, but leaves [-] alone.

(setq org-html-checkbox-type 'unicode)
(setq org-html-checkbox-types
      '((unicode (on . "<span class=\"task-done\">&#x2611;</span>")
                 (off . "<span class=\"task-todo\">&#x2610;</span>")
                 (trans . "<span class=\"task-in-progress\">[-]</span>"))))

Org Mode: Asynchronous export and tangle of a large file   org

I have a pretty large Emacs configuration file. It's annoying to wait 11 seconds for it to export to HTML or 12 seconds to tangle. Fortunately, Org Mode allows me to export asynchronously. I tried it out from org-export-dispatch (C-c C-e) by using the C-a option. It worked pretty well, but it was a bit slow because it loaded my full configuration. Fortunately, there's a way to use a smaller configuration that focuses on just the packages needed.

(setq org-export-async-init-file "~/.config/emacs/org-async-export-config.el")
(setq org-export-async-debug t)

I've named the source blocks, and this block assembles the config from those named blocks by using noweb.

Org protocol: following Org links from outside Emacs   org emacs

_xor had an interesting idea: can we use org-protocol to link to things inside Emacs, so that we can have a webpage with bookmarks into our Org files? Here's a quick hack that reuses org-store-link and org-link-open.

(defun org-protocol-open-link (info)
  "Process an org-protocol://open style url with INFO."
  (org-link-open (car (org-element-parse-secondary-string (plist-get info :link) '(link)))))

(defun org-protocol-copy-open-link (arg)
  (interactive "P")
  (kill-new (concat "org-protocol://open?link=" (url-hexify-string (org-store-link arg)))))

(with-eval-after-load 'org
  (add-to-list 'org-protocol-protocol-alist
               '("org-open" :protocol "open" :function org-protocol-open-link)))

To make exporting and following easier, we also need a little code to handle org-protocol links inside Org.

(defun org-protocol-follow (path &rest _)
  "Follow the org-protocol link for PATH."
  (org-protocol-check-filename-for-protocol (concat "org-protocol:" path) nil nil))

(defun org-protocol-export (path desc format info)
  "Export an org-protocol link."
  (setq path (concat "org-protocol:" path))
  (setq desc (or desc path))
  (pcase format
    (`html (format "<a href=\"%s\">%s</a>" path desc))
    (`11ty (format "<a href=\"%s\">%s</a>" path desc))
    (`latex (org-latex-link path desc info))
    (`ascii (org-ascii-link path desc info))
    (`md (org-md-link path desc info))
    (_ path)))

(with-eval-after-load 'org
  (org-link-set-parameters "org-protocol"
                           :follow #'org-protocol-follow
                           :export #'org-protocol-export))

Now I can use org-protocol-copy-open-link to copy a link to the current location, and I can put it into my Org files.

Example bare link to the Org manual, which will work only if you have open in the org-protocol-protocol-alist:

TODO Speed command for adding a custom ID to Org Mode posts

Nudged by Amit's post about adding custom IDs to Org headings, I decided to write a speed command to add a custom ID with a reasonable default, and to make it happen whenever I post something from my Emacs config (like this one). I'm running out of brainspace for speed commands, so I'm going to try sticking it into a hydra so that I can add future things to the hydra instead. I'll probably figure out some kind of cheat sheet thing for speed commands too.

I decide to combine or split categories depending on the number of links. I have a pretty consistent order. John Wiegley suggested promoting Emacs Lisp and Emacs development links at the top of the list. I like to sort the rest of the list roughly by interest: general links first, then Org, then coding, then other links at the bottom.

Here's some code that sorts Org lists in a custom sequence, with unknown items at the bottom for easy re-ordering. It will take a list like:

- Other:
  - Link A
  - Link B
- Emacs development:
  - Link A
  - Link B
- Emacs Lisp:
  - Link A
  - Link B

and turn it into:

- Emacs Lisp:
  - Link A
  - Link B
- Emacs development:
  - Link A
  - Link B
- Other:
  - Link A
  - Link B

Linking to and exporting function definitions in Org Mode   emacs org

  • [2024-01-11 Thu]: Added ?link=1 to copy the context link
  • 2023-09-12: added a way to force the defun to start open with ?open=1
  • 2023-09-05: fixed the completion to include defun:

I'd like to write more blog posts about little Emacs hacks, and I'd like to do it with less effort. Including source code is handy even when it's missing some context from other functions defined in the same file, since sometimes people pick up ideas and having the source code right there means less flipping between links. When I'm working inside my config file or other literate programming documents, I can just write my blog post around the function definitions. When I'm talking about Emacs Lisp functions defined elsewhere, though, it's a little more annoying to copy the function definition and put it in a source block, especially if there are updates.

The following code creates a defun link type that exports the function definition. It works for functions that can be located with find-function, so only functions loaded from .el files, but that does what I need for now. Probably once I post this, someone will mention a much more elegant way to do things. Anyway, it makes it easier to use org-store-link to capture a link to the function, insert it into a blog post, navigate back to the function, and export HTML.

DONE Scan ~/bin and turn the scripts into interactive commands

I want to automate little things on my computer so that I don't have to look up command lines or stitch together different applications. Many of these things make sense to turn into shell scripts. That way, I can call them from other programs and assign keyboard shortcuts to them. Still, I spend most of my computer time in Emacs, and I don't want to think about whether I've defined a command in Emacs Lisp or in a shell script. Besides, I like the way Helm lets me type parts of commands in order to select and call them.

Emacs Lisp allows you to define a macro that results in Emacs Lisp code. In this case, I want to define interactive functions so I can call them with M-x. In case I decide to call them from Emacs Lisp, such as (my-shell/rotate-screen "left"), I want to be able to pass arguments. I'm also using dash.el to provide functions like -filter and -not, although I could rewrite this to just use the standard Emacs Lisp functions.

Here's the code that scans a given directory for executable files and creates interactive functions, and some code that calls it for my ~/bin directory.

(use-package dash
  (defmacro my-convert-shell-scripts-to-interactive-commands (directory)
    "Make the shell scripts in DIRECTORY available as interactive commands."
    (cons 'progn
           (lambda (filename)
             (let ((function-name (intern (concat "my-shell/" (file-name-nondirectory filename)))))
               `(defun ,function-name (&rest args)
                   ((not (called-interactively-p 'any))
                    (shell-command-to-string (mapconcat 'shell-quote-argument (cons ,filename args) " ")))
                    (apply 'call-process-region (point) (mark) ,filename nil (if current-prefix-arg t nil) t args))
                    (apply 'call-process ,filename nil (if current-prefix-arg t nil) nil args))))))
           (-filter (-not #'file-directory-p)
                    (-filter #'file-executable-p (directory-files directory t))))))
  (my-convert-shell-scripts-to-interactive-commands "~/bin"))

Let's see how that goes!

Emacs: Making a hydra cheatsheet for Lispy   emacs

I wanted to get the hang of Lispy thanks to Leo Vivier's presentation at EmacsSF, but there are a lot of keyboard shortcuts to explore. In Karl Voit's demo of Org Mode at GLT21, he showed how he uses Hydra to make cheat sheets. That makes perfect sense, of course, as Hydra can display text and allow you to run commands while the text is displayed. I wanted to make a Hydra that would show me categorized commands to make it easier to look up and eventually remember them. I also wanted to skip the commands that I already knew or that I didn't want to focus on just yet.

Fortunately, the function reference had a link to the Org file used to generate it. I copied the tables, merged them together, named them with #+NAME: bindings, replaced the links with plain text, and added a third column with the category I wanted to put commands into.

I wrote this Emacs Lisp code with the header arguments #+begin_src emacs-lisp :var bindings=bindings :colnames yes:

  '(defhydra my-lispy-cheat-sheet (:hint nil :foreign-keys run)
     ("<f14>" nil "Exit" :exit t))
  (cl-loop for x in bindings
           unless (string= "" (elt x 2))
           (list (car x)
                 (intern (elt x 1))
                 (when (string-match "lispy-\\(?:eval-\\)?\\(.+\\)"
                                     (elt x 1))
                   (match-string 1 (elt x 1)))
                 (elt x 2)))))
(with-eval-after-load "lispy"
  (define-key lispy-mode-map (kbd "<f14>") 'my-lispy-cheat-sheet/body)
  (define-key lispy-mode-map (kbd "C-?") 'my-lispy-cheat-sheet/body))
(with-eval-after-load 'evil-lispy
  (evil-define-key nil evil-lispy-mode-map (kbd "<f14>") 'my-lispy-cheat-sheet/body))

Here's the result:

Figure 10: Hydra-based cheat sheet

I'm experimenting with having my Windows key be F14 if tapped and Super_L if held down. I use KDE, so I disabled the Applications shortcut with:

kwriteconfig5 --file ~/.config/kwinrc --group ModifierOnlyShortcuts --key Meta ""
qdbus org.kde.KWin /KWin reconfigure

and then used xcape -e 'Super_L=F14' to make it work.

Looking forward to getting the hang of this!
