Configuration   emacs

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. Note that use-package is itself provided by a package, so you'll probably want to install that and bind-key.

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.

Starting up

Here's how we start:

;; 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)

System information

(defvar my-laptop-p (equal (system-name) "sacha-x220"))
(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

Personal information

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

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")
(unless (package-installed-p 'use-package)
  (package-install 'use-package))
(setq use-package-verbose t)
(setq use-package-always-ensure t)
(require 'use-package)
(use-package quelpa)
(use-package quelpa-use-package)
(use-package auto-compile
  :if my-laptop-p
  :config (auto-compile-on-load-mode))
(setq load-prefer-newer t)

General configuration

(repeat-mode 1)
;; don't interrupt me with native compilation warnings

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 prefixarg 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.

(use-package dash :ensure t)
(use-package diminish :ensure t)


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)))

Windows configuration   drill

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)

Time in the modeline

I like having the clock.

(display-time-mode 1)

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>.

Sentences end with a single space

In my world, sentences end with a single space. This makes sentence navigation commands work for me.

Trying out Marginalia, Selectrum, Embark, and Consult

Based on BSAG » Switching to Selectrum for incremental narrowing in Emacs I like marginalia for M-x, but I've gotten used to Helm for finding files.

Marginalia and hiding the value of password-ish variables

This code is no longer needed because marginalia.el hides the values of variables matching marginalia-censor-variables.

I like the way Marginalia adds annotations to minibuffer completion. I'm experimenting with streaming, so I'm trying to not leak passwords while playing around with marginalia. (I'll probably mess up at some point. Please be nice! =))

This is the annotator function I used to have:

(defun my-marginalia-annotate-variable (cand)
  "Annotate variable CAND with its documentation string."
  (when-let (sym (intern-soft cand))
     ((marginalia--symbol-class sym) :face 'marginalia-modified)
     ((let ((print-escape-newlines t)
            (print-escape-control-characters t)
            (print-escape-multibyte t))
          ((string-match "pass" cand) "*******")
          ((boundp sym) (symbol-value sym))
          (t 'unbound))))
      :truncate (/ marginalia-truncate-width 3) :face 'marginalia-variable)
     ((documentation-property sym 'variable-documentation)
      :truncate marginalia-truncate-width :face 'marginalia-documentation))))
Marginalia and annotating journal entries

I used to annotate functions with their arguments, but that seems to be built-in now. The following code annotates journal entries with their categories.

(defun my-marginalia-annotate-journal (cand)
  (when-let ((o (cdr (assoc cand my-journal-search-cache))))
     ((plist-get o :Category)
:face 'marginalia-documentation
:truncate 13))))

Helm - interactive completion

Helm makes it easy to complete various things. I find it to be easier to configure than ido in order to get completion in as many places as possible, although I prefer ido's way of switching buffers.

Getting Helm and org-refile to clock in or create tasks   emacs org helm

I've been thinking about how to improve the way that I navigate to, clock in, and create tasks in Org Mode. If the task is one of the ones I've planned for today, I use my Org agenda. If I know that the task exists, I use C-u C-c C-w (org-refile) to jump to it, and then ! (one of my org-speed-commands-user options) to clock in and track it on Quantified Awesome. If I want to resume an interrupted task, I use C-u C-c j (my shortcut for org-clock-goto). For new tasks, I go to the appropriate project entry and create it, although I really should be using org-capture instead.

2015-01-30 Org Mode jumping to tasks – index card #emacs #org

I thought about how I can reduce some of these distinctions. For example, what if it didn't matter whether or not a task already exists? I can modify the org-refile interface to make it easier for me to create tasks if my description doesn't match anything. To make things simpler, I'll just reuse one of my org-capture-templates, and I'll pre-fill it with the candidate from Helm.

(ert-deftest my-org-capture-prefill-template ()
   ;; It should fill things in one field at ia time
     "* TODO %^{Task}\nSCHEDULED: %^t\n:PROPERTIES:\n:Effort: %^{effort|1:00|0:05|0:15|0:30|2:00|4:00}\n:END:\n%?\n"

Next, I want to add this to the way that Helm prompts me to refile. That means that my creation task should return something ready for org-refile. Actually, maybe I don't have to do that if I know I'm always going to call it when I want to jump to something. I might as well add that bit of code that sets up clocking in, too.

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.

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))

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.

  (when (display-graphic-p)

  :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.

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")))))

Repeatable commands

Based on . Modified to accept nil as the first value if you don't want the keymap to run a command by default, and to use kbd for the keybinding definitions.

(defun my-def-rep-command (alist)
  "Return a lambda that calls the first function of ALIST.
      It sets the transient map to all functions of ALIST,
      allowing you to repeat those functions as needed."

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.

(use-package windmove
  (("<f2> <right>" . windmove-right)
   ("<f2> <left>" . windmove-left)
   ("<f2> <up>" . windmove-up)
   ("<f2> <down>" . windmove-down)

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.

(setq bookmark-watch-bookmark-file 'silent)

Key chords

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)))

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.

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

  (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.

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:

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.

(require 'dash)

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.

Adding steno hints as I type   steno emacs

When I type with steno, I want to see little hints. I borrowed some code from company-posframe to display hints based on the last few words, even ones I ended up fingerspelling or typing on my keyboard. This makes it easier to learn new words if I have to spell them out. There's probably a better way to do it, but this is a good start.

Using inotify to add Plover Clippy suggestions into Emacs

Update 2021-06-19: Changed to a vertical layout, added extra notes, simplified

I don't have a lot of screen space on my laptop, so I don't usually have the Plover suggestion window open as I type. I came up with a Plover plugin to let me flash the last Plover Clippy suggestion as a temporary notification. It went by too quickly, though, so I wrote something that uses inotify to monitor the clippy.txt log and put it an Emacs buffer instead. It results in text like this:

(defvar my-clippy-recent-suggestions nil "Recent suggestions, limited by `my-clippy-recent-suggestions-limit`.")
(defvar my-clippy-recent-suggestions-limit nil "If non-nil, keep this many suggestions.")
(defvar my-clippy-extra-notes nil "Extra notes to add at the end.")
(defun my-clippy-last ()
  (let ((value (string-trim (shell-command-to-string "tail -1 ~/.config/plover/clippy.txt | cut -c 23-"))))
    (when (string-match "^\\(.*?\\)[ \t]+|| .*? -> \\(.+\\)" value)
      (cons (match-string 1 value) (match-string 2 value)))))

TOBLOG Manage photos with geeqie

Opening images directly in Emacs seems a little slow. Geeqie is pretty fast (after generating thumbnails) and can be remotely controlled via the command-line. I wrote a few functions to help me flip through images, add extra stuff to filenames, change dates, and insert references.

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.

(with-eval-after-load 'org
  (bind-key "C-c k" 'org-cut-subtree org-mode-map)
  (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
              ("C-c b" . my-org-back-to-heading)
              ("C-c p" . org-display-outline-path)))
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.

(defun my-org-contacts-template-email (&optional return-value)

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

    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)
  • Habits

    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.

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!

Quick way to archive all DONE from inbox   emacs computer
(defun my-org-clean-up-inbox ()
  "Archive all DONE tasks and sort the remainder by TODO order."

    (my-org-archive-done-tasks 'file)
    (goto-char (point-min))
    (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.
       SCOPE can be 'file or 'tree."
   (lambda ()
     (setq org-map-continue-from (outline-previous-heading)))
   "TODO=\"DONE\"|TODO=\"CANCELLED\"" (or scope (if (org-before-first-heading-p) 'file 'tree))))


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")
        ("e" . "example")
        ("E" . "export")
        ("m" . "export md")
        ("h" . "export html")
        ("l" . "src emacs-lisp")
        ("p" . "src python")
        ("q" . "quote")
        ("s" . "src")
        ("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))

  (interactive (list (read-string "URL: " (org-entry-get-with-inheritance "YOUTUBE")) (point) (mark)))
      (narrow-to-region beg end)
      (goto-char (point-min))
      (let ((char (if (string-match "\\?" url) "&" "?")))

                   (or (match-string 5) "0")
                   (match-string 1)) nil t))))))

(defun my-clean-up-google-hangout-chat ()

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.

Quickly refiling Org Mode notes to headings in the same file

I wanted a quick way to organize random notes from my inbox into an outline, organizing from the bottom up instead of starting with a top-down hierarchy. My old code for refiling to an Org heading in the current buffer didn't work any more, but helm-org-in-buffer-headings seems to be promising. I made it a speed command (see the value of org-use-speed-commands elsewhere in my config) so that I can easily refile.

(defvar my-org-last-refile-marker nil "Marker for last refile")
(defun my-org-refile-in-file (&optional prefix)
  "Refile to a target within the current file."
  (let ((org-refile-targets (list (cons (list (buffer-file-name)) '(:maxlevel . 5)))))
    (call-interactively 'org-refile)
    (setq my-org-last-refile-marker (plist-get org-bookmark-names-plist :last-refile))))

(defun my-org-refile-to-previous ()

              (with-current-buffer (marker-buffer marker)
                (goto-char (marker-position marker))
        (helm-org-goto-marker marker)
        (org-end-of-subtree t t)
        (org-paste-subtree target-level)))))

(with-eval-after-load 'org
  (let ((listvar (if (boundp 'org-speed-commands) 'org-speed-commands
    (add-to-list listvar '("w" call-interactively 'org-refile))
    (add-to-list listvar '("W" call-interactively 'my-org-refile-in-file))
    (add-to-list listvar '("." call-interactively 'my-org-refile-to-previous))))

TODO: Figure out why I'm getting duplicates. Next step might be to fiddle with helm-org-in-buffer-headings so that it preselects the previous candidate, but that can happen later.

Tech note: helm-org doesn't use the usual org-refile mechanism. Instead, it cuts the subtree, goes to the marker, and pastes it in at the appropriate level.

Let's try literate-elisp
(use-package literate-elisp :if my-laptop-p)

Then I should be able to use literate-elisp-load-file and still be able to jump to functions by definition.


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

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.

 :follow #'my-include-open
 :export #'my-include-export
 :complete #'my-include-complete)

    (find-file path)
    (setq start
            (plist-get params :from-regexp)
              (goto-char (point-min))

  • 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
                (lambda (el)
                   (org-element-property :key el)
                   (org-element-property :value el)
                    (org-element-property :begin el)
                    (org-element-property :end el))))))
             (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
                   (mapconcat (lambda (file-prop) (elt file-prop 2))
        (find-file filename)
        (goto-char (point-min))))

    Then this adds a link to it:

    (defun my-org-export-filter-body-add-index-link (string backend info)
      (if (and
           (member backend '(11ty html))
           (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)))))
          (concat string
                  (format "<div><a href=\"\">View org source for this post</a></div>"
                          (plist-get info :permalink)))
    (with-eval-after-load 'ox
      (add-to-list 'org-export-filter-body-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)))
               ?o (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)))
Special blocks

  :if my-laptop-p
  :hook (org-mode . org-special-block-extras-mode)
  ;; Use short names like ‘defblock’ instead of the fully qualified name

  (setcdr org-special-block-extras-mode-map nil)
  (org-defblock my_details (title "Details") (title-color "Green")
              "Top level (HTML & 11ty)OSPE-RESPECT-NEWLINES? Enclose contents in a folded up box."
               ((eq backend '11ty)
                 "{%% details \"%s\"%%}\n%s\n{%% enddetails %%}"
                 title contents))
               ((eq backend 'html)

                      <font face=\"Courier\" size=\"3\" color=\"%s\">
                 title-color title contents))))

  (org-defblock columns nil nil
              "Top level (HTML & wp & 11ty)OSPE-RESPECT-NEWLINES? Split into columns using Foundation."
              (format "<div class=\"row\">%s</div>" contents))
  (org-defblock column50 nil nil
              "Top level (HTML & wp & 11ty)OSPE-RESPECT-NEWLINES? Split into columns."
              (format "<div class=\"columns small-12 medium-6 large-6\">%s</div>" contents))

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.

(setq org-babel-exp-code-template "#+begin_src %lang%switches%flags :summary %summary\n%body\n#+end_src")
(defun my-org-html-src-block (src-block _contents info)
  (let* ((result (org-html-src-block src-block _contents info))
          (org-with-point-at (org-element-property :begin src-block)
         (summary (assoc-default :summary (elt block-info 2))))
    (if (member summary '("%summary" ""))
      (format "<details><summary>%s</summary>%s</details>"
(with-eval-after-load 'ox-html
   (org-export-backend-transcoders (org-export-get-backend 'html))
   'src-block 'my-org-html-src-block))

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)

Make it easy to scroll to the top:

(setq org-html-preamble "<a name=\"top\" id=\"top\"></a>")
(setq org-html-postamble "
       <style type=\"text/css\">
       .back-to-top {
           position: fixed;
           bottom: 2em;
           right: 0px;
           text-decoration: none;
           color: #000000;
           background-color: rgba(235, 235, 235, 0.80);
           font-size: 12px;
           padding: 1em;
           display: none;

       .back-to-top:hover {
           background-color: rgba(135, 135, 135, 0.50);

       <div class=\"back-to-top\">
       <a href=\"#top\">Back to top</a> | <a href=\"\">E-mail me</a>

       <script type=\"text/javascript\">
           var offset = 220;
           var duration = 500;
           jQuery(window).scroll(function() {
               if (jQuery(this).scrollTop() > offset) {
               } else {
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)

      '((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.


This is what the code looks like when it's expanded:

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.

Sorting Org Mode lists using a sequence of regular expressions   emacs org

I manually categorize Emacs News links into an Org unordered list, and then I reorganize the list by using M-S-up (org-shiftmetaup) and M-S-down (org-shiftmetadown). 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

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.

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)
  (emacs-lisp-mode . highlight-sexp-mode)
  (defun my-hl-sexp-update-overlay ()
    (when (overlayp hl-sexp-overlay)
         ,(if (fboundp 'modus-themes-get-color-value)
              (modus-themes-get-color-value 'bg-inactive)
  (defun my-hl-sexp-update-all-overlays ()
    (dolist (buf (buffer-list))
      (with-current-buffer buf
        (when highlight-sexp-mode
  (advice-add 'hl-sexp-create-overlay :after 'my-hl-sexp-update-overlay)
  (advice-add 'modus-themes-toggle :after 'my-hl-sexp-update-all-overlays))

This is what it looks like:

I like js2-mode.

(add-to-list 'auto-mode-alist '("\\.js\\'\\|\\.json\\'" . js2-mode))

Handy shortcuts:

(use-package js2-mode
  :if my-laptop-p
  :mode "\\.js\\'"
  :bind (:map js2-mode-map ("C-c C-c" . projectile-compile-project)))
(use-package coffee-mode

  :after js2-mode
  :hook ((js2-mode . jasminejs-mode)
         (jasminejs-mode-hook . jasminejs-add-snippets-to-yas-snippet-dirs)))

This makes script blocks easier to copy:

(defvar my-javascript-test-regexp (concat (regexp-quote "/** Testing **/") "\\(.*\n\\)*")
  "Regular expression matching testing-related code to remove.
      See `my-copy-javascript-region-or-buffer'.")

(defun my-copy-javascript-region-or-buffer (beg end)
  "Copy the active region or the buffer, wrapping it in script tags.
      Add a comment with the current filename and skip test-related
      code. See `my-javascript-test-regexp' to change the way
      test-related code is detected."
  (interactive "r")
  (unless (region-active-p)

    (if (buffer-file-name) (concat "// " (file-name-nondirectory (buffer-file-name)) "\n") "")
     (buffer-substring (point-min) (point-max))

This makes it easier to debug:

(defvar my-debug-counter 1)
(defun my-insert-or-flush-debug (&optional reset beg end)
  (interactive "pr")
   ((= reset 4)
      (flush-lines "console.log('DEBUG: [0-9]+" (point-min) (point-max))

    (insert (format "console.log('DEBUG: %d');\n" my-debug-counter))

Make files executable if the first file has a shebang (ex: #!/bin/bash#)

  "Execute DWIM shell command asynchronously using noweb templates.

Which files

  `dwim-shell-command' attempts to guess which file(s) you may want
  the command to operate on.

  1. If visiting a `dired' buffer, draw the marked file(s).
  2. If visiting any other buffer with an associated file, use that.


  Operate on drawn files using either the following:

    <<f>> (file path,used by default)
    <<fne>> (file path without extension)
    <<e>> (extension)
    <<td>> (generate a temporary directory)
    <<*>> (all files joined)
    <<cb>> (clipboard)
    <<n>>, <<1n>>, or <<An>> (for current iteration)

  For example:

    With drawn files '(\"path/to/image1.png\" \"path/to/image2.png\")

   \"convert '<<f>>' '<<fne>>.jpg'\" expands to

     \"convert 'path/to/image1.png' 'path/to/image1.jpg'\"
     \"convert 'path/to/image2.png' 'path/to/image2.jpg'\"

   while \"ls -lh <<*>>\" expands to

     \"ls -lh path/to/image1.png path/to/image2.png\"


  `dwim-shell-command' creates a process buffer to capture command
  output, but doesn't display or focus on it by default.  Instead,
  it tries to guess what's more convenient to focus on.

  While the process is busy, show a spinner in the minibuffer.  No
  focus changes.

  After process is finished:

  1. If there were any files created in the `default-directory',
  jump to a `dired' buffer and move point to the new file (via

  2. If no new files were created, automatically switch focus to the
  process buffer and display its output.

    Note: You can prevent this automatic focus by prepending your
    command with whitespace.

    \" convert '<<f>>' '<<fne>>.jpg'\"

  3. If the shell command caused any errors, offer to focus the
  process buffer and display its output.

Quick exit

  Process buffers are read-only and can be quickly closed by
  pressing `q'.

The proper way to implement this is probably to patch or override the definition of magit-git-insert-section so that it takes a list of options to add at the end of the command, but that can wait for another time (or braver souls).

Collecting Emacs News from Mastodon

One of the things I like about browsing Mastodon in Emacs using mastodon.el is that I can modify my workflow to make things easier. For example, I often come across links that I'd like to save for Emacs News. I want to boost the post and save it to an Org file, and I can do that with a single keystroke. It uses the my-mastodon-store-link defined elsewhere in my config.

(use-package org

Posting the latest screenshot with mastodon.el

I want to make it easier to microblog the latest screenshot, or a recent screenshot if I need to pick a different one. It might also be a good time to add some text to the filename to make it easier to find later on. I can use that text as alt-text for the image, too.

Making it easier to toot my config

The following snippet composes a toot buffer with a link to the relevant section of my configuration file, or to the relevant blog post if specified.

Collect my recent toots in an Org file so that I can refile them

I want to use my microblog posts on Mastodon as building blocks for longer posts on my blog. Getting them into an Org file makes it easier to link to them or refile them to other parts of my Org files so that I can build up my notes.

                             (xml-parse-region (point-min) (point-max)))
                "html" "org")
          "\n\n[" (format-time-string (cdr org-time-stamp-formats)
                                      (date-to-time (plist-get entry :pubDate)))
"]\n" (plist-get entry :link)))
(setq org-feed-alist '(("Mastodon" ""

Using Spookfox to scroll Firefox up and down from Emacs   web emacs

I open lots of pages in the process of making Emacs News. I like to open the pages in Mozilla Firefox, but I want the keyboard focus to stay with Emacs so that I can quickly categorize the links. I also sometimes want to scroll the page up or down. While reading the Reading, and not forgetting post, I came across Spookfox, which bridges Emacs and Firefox using an Firefox add-on and websockets. After I started spookfox and connected to it by clicking on the extension in Firefox, I was able to interact with it from Emacs Lisp. I feel a little nervous about it security-wise, but at least it's only listening on the local port. There might be another way to do it with the Marionette support in Firefox, but I haven't looked into it yet.

(use-package spookfox
  :quelpa (spookfox :fetcher github :repo "bitspook/spookfox"
                    :files ("lisp/*.el" "lisp/apps/*.el"))
  :when my-laptop-p
  (require 'spookfox-tabs)
  (require 'spookfox-org-tabs)
  (require 'spookfox-js-injection)
  (add-to-list 'spookfox-enabled-apps 'spookfox-tabs)
  (add-to-list 'spookfox-enabled-apps 'spookfox-org-tabs)
  (add-to-list 'spookfox-enabled-apps 'spookfox-js-injection)
  ;; (spookfox-init) ; don't automatically enable it; run (spookfox-init) to manually enable

Anyway, this code seems to do the job of scrolling my Firefox window:

(defun my-spookfox-scroll-down ()
  (spookfox-eval-js-in-active-tab "window.scrollBy(0, document.documentElement.clientHeight);"))

(defun my-spookfox-scroll-up ()
  (spookfox-eval-js-in-active-tab "window.scrollBy(0, -document.documentElement.clientHeight);"))

(global-set-key (kbd "C-s-v") 'my-spookfox-scroll-down)
(global-set-key (kbd "C-s-S-v") 'my-spookfox-scroll-up)

This code opens a tab without switching keyboard focus away from Emacs:

(defun my-spookfox-background-tab (url &rest args)
  "Open URL as a background tab."
  (if spookfox--connected-clients
      (spookfox-tabs--request (cl-first spookfox--connected-clients) "OPEN_TAB" `(:url ,url))
    (browse-url url)))

My Emacs News code for processing my upvoted Reddit posts can automatically grab the links from Reddit link posts, but sometimes people post Reddit text or image posts and then include the link to the actual project in the post body or a comment instead.

(defun my-spookfox-get-links ()
   (spookfox-eval-js-in-active-tab "[...(document.querySelector('[data-testid=post-container]')?.parentElement || document).querySelectorAll('a')].map(a => a.href).filter(a => a && (! || !a.match(/redd\.?it/)) && !a.match(" t)))
(defun my-presorted-completion-table (completions)
  (lambda (string pred action)
    (if (eq action 'metadata)
          (cycle-sort-function . identity)
          (display-sort-function . identity))
      (complete-with-action action completions string pred))))

(defun my-spookfox-complete-link (&optional prompt)
   (or prompt "Link: ")

(defun my-spookfox-insert-link-from-page (link)
  (interactive (list (my-spookfox-complete-link)))
  (insert (org-link-make-string link (my-page-title link))))

(defun my-spookfox-open-link-from-page (link)
  (interactive (list (my-spookfox-complete-link)))
  (my-spookfox-background-tab link))

(defun my-spookfox-insert-link-to-tab ()
  (let ((tab (spookfox-request-active-tab)))
    (insert (org-link-make-string
             (plist-get tab :url)
             (plist-get tab :title)))))

I use Gmail for my mail because it:

  • synchronizes with my phone, which is handy for notifications and quick replies
  • filters most of the spam for me
  • works with a few interesting extensions such as Boomerang for Gmail

    However, I like the way the Gnus mail/news client in Emacs gives me a much more keyboard-friendly way to manage lots of mail, and I can even write code to partially automate some of my common operations.

    I used to have my config in in ~/.gnus, but people might find it handy, so I've added it to my public Emacs configuration.

    I like using Gmane to read mailing lists, and I use IMAP to read my Gmail.

    (setq gnus-select-method '(nnnil ""))
    (setq gnus-secondary-select-methods
          '((nntp "")
            ;; (nnmaildir "mail"
            ;;            (directory "~/Maildir/")
            ;;            (directory-files nnheader-directory-files-safe)
            ;;           (get-new-mail nil))
            ;; (nnimap ""
            ;;         (nnimap-address "")
            ;;         (nnimap-server-port 993)
            ;;         (nnimap-stream ssl)
            ;; (nnimap-authenticator login))
            (nnimap "localhost"
              (nnimap-address "localhost")
              (nnimap-stream network)
              (nnimap-user "sacha")
              (nnimap-authenticator login)
              (nnimap-authinfo-file "~/.authinfo.gpg"))
    (setq smtpmail-smtp-server ""
          smtpmail-smtp-service 587
          smtpmail-auth-credentials "~/.authinfo.gpg"
          send-mail-function 'smtpmail-send-it
          message-send-mail-function 'smtpmail-send-it
          gnus-check-new-newsgroups nil
          gnus-activate-level 2
          gnus-ignored-newsgroups "^to\\.\\|^[0-9. ]+\\( \\|$\\)\\|^[\"]\"[#'()]")

    I now use Dovecot with OfflineIMAP for local IMAP access to my mail and synchronization with Gmail, but you can see the commented-out information for Gmail in case you prefer that. I have two-factor authentication enabled for Gmail, so I set up an app-specific password for Gnus. I have GPG set up for encryption, and an ~/.authinfo.gpg file set up with something like:

    machine login password mysecretapppassword
    machine login password mysecretapppassword port 993
    machine login password mysecretapppassword port 587
    machine localhost login sacha password mysecretlocalpassword port 993
    machine localhost login sacha password mysecretlocalpassword port 143

    If you don't have GPG set up and you don't mind saving your passwords in the clear, you can set up an ~/.authinfo file instead.

    Sending e-mail on Windows was a bit of a pain. Fortunately, I eventually found something that works. I've configured emailrelay to accept the mail and forward it to Gmail. The server starts with this batch file:

    start "emailrelay" "C:\Program Files (x86)\emailrelay\emailrelay.exe" --as-proxy --client-auth "C:/sacha/.emailrelay" --client-tls --log --pid-file "C:\Program Files (x86)\emailrelay\" --spool-dir C:\sacha\tmp\emailrelay

    Sending queued mail works with this batch file:

    "c:\Program Files (x86)\emailrelay\emailrelay.exe" --as-client --client-auth c:\sacha\.emailrelay --client-tls --spool-dir c:\sacha\tmp\emailrelay

    I should probably get around to using --as-proxy properly, since it still seems to hold mail until I explicitly send it.

    On Linux, it's simply a matter of setting up a mail server such as Postfix.

    Hide HTML mail. I need to fiddle with this some more, since Gnus still tries to display them. Sometimes my Gnus crashes when it tries to display HTML mail.

    (use-package gnus
      (require 'mm-decode)
      (setq mm-discouraged-alternatives
            '("text/html" "text/richtext")

    Hide quoted text.

Emacs server

(server-start) permits the use of emacsclient, emacsclientw, and org-protocol. I used to start a server as part of my config. Now I'm switching to using emacs --daemon, which starts a server automatically. Anyway, with --daemon, Emacs doesn't start off in a graphical environment, so the frames that emacsclient -c creates don't get the theme applied. This fixes that:

Deleting things

  "Kill the region between the mark and the closest portion of
      the isearch match string. The behaviour is meant to be analogous
      to zap-to-char; let's call it zap-to-isearch. The deleted region
      does not include the isearch word. This is meant to be bound only
      in isearch mode.  The point of this function is that oftentimes
      you want to delete some portion of text, one end of which happens
      to be an active isearch word. The observation to make is that if
      you use isearch a lot to move the cursor around (as you should,
      it is much more efficient than using the arrows), it happens a
      lot that you could just delete the active region between the mark
      and the point, not include the isearch word."

Controlling my stream audio from Emacs: background music, typing sounds, and push to talk   emacs

Update: 2021-02-11: Parsed pacmd list-sources so that I can mute/unmute devices by regular expression. Update: 2021-02-07: Made it work with my USB microphone.

I was experimenting with streaming Emacs geeking around on Someone asked me to have soft background music and typing sounds. Since I'm a little clueless about music and don't want to bother with hunting down nice royalty-free music, I figured I could just use the Mozart dice game to programmatically generate music.

I installed the mozart-dice-game NPM package and used this bit of Javascript to generate a hundred MIDI files.

const x = require('mozart-dice-game')
for (let i = 0; i < 100; i++) { x.saveMinuet('minuet' + String(i).padStart('3', '0') + '.mid'); }

Then I wrote this Emacs Lisp function to turn it on and off.

(defvar my-background-music-process nil "Process for playing background music")
(defun my-stream-toggle-background-music (&optional enable)
  (if (or my-background-music-process
          (and (numberp enable) (< enable 0)))
        (when (process-live-p my-background-music-process)
          (kill-process my-background-music-process))
        (setq my-background-music-process nil))
    (let ((files (directory-files "~/proj/music" t "mid\\'")))
      (setq my-background-music-process
             (append (list "timidity" "-idlr" "--volume=10") files))))))

People also suggested typing sounds. I guess that's a good way to get a sense of activity. The default selectric sound was a little too loud for me, so we'll use the move sound for now. It would be nice to make this more random-sounding someday.

(defun my-selectric-type-sound ()
  "Make the sound of typing."
  ;; Someday, randomize this or something
  (selectric-make-sound (expand-file-name "selectric-move.wav" selectric-files-path)))

I was having a hard time remembering to go back on mute during meetings, since the LED on the mute button wasn't working at the time and the system tray icon was a little hard to notice. The LED has mysteriously decided to start working again, but push-to-talk is handy anyway. I want to be able to tap a key to toggle my microphone on and off, and hold it down in order to make it push-to-talk. It looks like my key repeat is less than 0.5 seconds, so I can set a timer that will turn things off after a little while. This code doesn't pick up any changes that happen outside Emacs, but it'll do for now. I used pacmd list-sources to list the sources and get the IDs.

Might need to tweak it because I use the Dvorak layout, so hjkl doesn't make as much sense for me.

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 4: 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!

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!
