#+TITLE: Álvaro Ramírez #+AUTHOR: Álvaro Ramírez #+OPTIONS: toc:nil num:nil ^:nil * [2024-09-21 Sat] How I batch apply and save one-liners :PROPERTIES: :CUSTOM_ID: how-i-batch-apply-and-save-one-liners :END: My significant other needed to share proof of address by providing a number of bank statements for a period of time. That's easy enough to download as pdfs from the bank, but statements typically provide more personal information than the recipient requires. For a proof of address, the first page is more than enough. macOS's Preview app can easily delete pages from a pdf by selecting undesired pages and hitting the delete key. This is fine for one pdf but for a handful of them, I figured there's a command line incantation I could use out there, and indeed there is: #+begin_src sh qpdf my.pdf --pages . 1 -- my-one-page.pdf #+end_src With command in mind, I resorted to my now my typical approach of: - Convert to a generic [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]]. - Batch apply. I could be done at this point, but since I now have the command fresh in mind... - Save command for future usage. So let's get on with it. ** Converting to dwim-shell-command #+begin_src sh qpdf '<>' --pages . 1 -- '<>_1.<>' #+end_src ** Batch apply Other than show it in action, it may be worth mentioning dwim-shell-command recognizes files in region (in addition to dired's mark of course), so you can just select and apply. #+ATTR_HTML: :width 95% [[file:images/how-i-batch-apply-and-save-one-liners/keep-1-page.gif]] ** Save for future usage Saving these commands for future usage typically consists of merely wrapping in an Emacs command so we can invoke via M-x (and your favorite narrowing framework for that fuzzy quick magic). #+begin_src emacs-lisp :lexical no (defun dwim-shell-commands-keep-pdf-page () "Keep a page from pdf." (interactive) (let ((page-num (read-number "Keep page number: " 1))) (dwim-shell-command-on-marked-files "Keep pdf page" (format "qpdf '<>' --pages . %d -- '<>_%d.<>'" page-num page-num) :utils "qpdf"))) #+end_src For this instance, there's a tiny bit of additional logic to ask the user which page they'd like to keep. While there's no way I'll remember =qpdf my.pdf --pages . 1 -- my-one-page.pdf=, I can easily find it in the future by searching with something like =M-x keep page=. #+ATTR_HTML: :width 95% [[file:images/how-i-batch-apply-and-save-one-liners/keep-1-page-command.gif]] ** My toolbox I've saved a bunch of these commands and use many of them regularly.

From Emacs, I normally use [[https://github.com/xenodium/chatgpt-shell][chatgpt-shell]]'s =chatgpt-shell-prompt-compose=, which automatically grabs the active region. This led me to explore a few options to select a region, or maybe even roll my own. I should also mention, these regions don't typically require compilable/complete structures. In most of these instances, I just reach out to one of my region favourites like [[https://github.com/magnars/expand-region.el][expand-region]], =mark-defun=, or =mark-whole-buffer=. Alternatively, I navigate to different points using sexp commands like =backward-sexp= and =forward-sexp= (or maybe something like =sp-backward-up-sexp= from [[https://github.com/Fuco1/smartparens][smartparens]]), using =set-mark-command= in-between to activate the region. While these commands typically yield balanced expressions, it's often unnecessary for my LLM queries. This led me to [[https://indieweb.social/@xenodium/113158018599745252][ask folks]] for different ways of selecting regions, which highlighted great package suggestions like [[https://github.com/abo-abo/avy][avy]], [[https://github.com/meow-edit][meow]], and [[https://github.com/leoliu/easy-kill][easy-kill]]. While I've been intrigued by =meow='s modal editing for some time, I'm not ready for that fair trial jump. Will have to postpone it for a little longer. =Easy-kill= offers =easy-mark=, in some ways similar to the built-in =mark-sexp=, but with additional marking heuristics and possibly other goodies I missed. At present, I get similar benefits from the likes of =expand-region= and the other sexp helpers. =Avy='s =avy-kill-ring-save-region= could work for my purpose, though I wish it left the region active. Maybe that's already possible? I could look into extending =avy=, though [[https://mastodon.social/@ctietze/113154167264208507][Christian's suggestions]] led me to lean more on visual feedback in my own region-expanding experiments. The goal was to enable extending regions in both vertical directions by simultaneously adding lines at both ends. Sure, this doesn't guarantee structural completeness, but it may just be enough for my LLM-feeding purpose. Maybe this already exists in the Emacs universe, but hey, it's an excuse to throw some elisp lines together... Assuming there's an existing active region, expanding in both directions is pretty straightforward. #+begin_src emacs-lisp :lexical no (defun bubble-expand() "Expand region." (interactive) (when (> (point) (mark)) (exchange-point-and-mark)) (forward-line -1) (exchange-point-and-mark) (forward-line 1) (exchange-point-and-mark)) (defun bubble-shrink () "Shrink region." (interactive) (when (< (point) (mark)) (exchange-point-and-mark)) (forward-line -1) (exchange-point-and-mark) (forward-line 1)) #+end_src While I've yet to use this region-expanding approach long enough to validate its usefulness, it sure is fun to play with it. #+ATTR_HTML: :width 75% [[file:images/emacs-bubble-mode/bubble-expand-shrink.gif]] This got me thinking, what other funky things I could do with the region? Could I shift the region selection like a viewport of sorts? As you now expect, the answer in Emacs is almost always of course we can... #+begin_src emacs-lisp :lexical no (defun bubble-shift-up () "Shift the region up by one line." (interactive) (when (> (point) (mark)) (exchange-point-and-mark)) (forward-line -1) (forward-line 0) (exchange-point-and-mark) (forward-line -1) (end-of-line) (activate-mark) (exchange-point-and-mark)) (defun bubble-shift-down () "Shift the region down by one line." (interactive) (when (> (point) (mark)) (exchange-point-and-mark)) (forward-line) (forward-line 0) (exchange-point-and-mark) (forward-line) (end-of-line) (activate-mark) (exchange-point-and-mark)) #+end_src #+ATTR_HTML: :width 75% [[file:images/emacs-bubble-mode/bubble-shift.gif]] My friend Vaarnan also suggested looking into UX around providing line count, which is possible by providing a prefix into =bubble-expand-region=. #+begin_src emacs-lisp :lexical no C-5 M-x bubble-expand-region #+end_src #+ATTR_HTML: :width 75% [[file:images/emacs-bubble-mode/bubble-number.gif]] These commands alone aren't as effective unless we have some key-bindings around them. I've tied things up into a minor mode, called... you guessed it: =bubble-mode=. Oooh, a mode, you may say it's now official ;) Well, no. It's still an experiment of sorts and currently lives in [[https://github.com/xenodium/dotsies/blob/main/emacs/ar/bubble.el][my Emacs config repo]]. The key bindings I've chosen are: - =C-c C-w=: Enter bubble-mode. - =C-p=: bubble-expand. - =C-n=: bubble-shrink. - =S-C-p=: bubble-move-up. - =S-C-n=: bubble-move-down. - =Numbers 1-0=: Expand 1 to 10 lines. - =RET=: Exit bubble-mode. Note: Inspired by expand-region, any other key binding/command automatically exits =bubble-mode=. =C-c C-w= kinda works for me as =C-c w= is already bound to =expand-region=. Let's see if that sticks, though I may have to give up the =org-refile= binding. So does it work for my original LLM intent? We shall see, but it seems to so far. You can play with it if you'd like (it's on [[https://github.com/xenodium/dotsies/blob/main/emacs/ar/bubble.el][github]]).

Posting messages to this area from elisp couldn't be simpler: #+begin_src emacs-lisp :lexical no (message "Hello world") #+end_src #+ATTR_HTML: :width 75% [[file:images/spiffing-up-those-echo-messages/svg-hello-world.gif]] If we want to get a little fancier, we can propertize the text to add some styling. #+begin_src emacs-lisp :lexical no (message (propertize "hello " 'face '(:foreground "#C3E88D")) (propertize "world" 'face '(:foreground "#FF5370"))) #+end_src #+ATTR_HTML: :width 75% [[file:images/spiffing-up-those-echo-messages/svg-hello-world-colors.gif]] With this in mind, I set out to add a tiny command to [[https://github.com/xenodium/ready-player][ready-player]]. I wanted the ability to ask what's on without switching to another buffer. The echo area is perfect for that. It should display track title, artist, and album. #+begin_src emacs-lisp :lexical no (message (concat "Ahead " ;; title (propertize "Wire " 'face '(:foreground "#C3E88D")) ;; artist (propertize "The Ideal Copy" 'face '(:foreground "#FF5370")))) ;; album #+end_src #+ATTR_HTML: :width 75% [[file:images/spiffing-up-those-echo-messages/svg-ready-player-colors.gif]] This kinda works, but I wasn't convinced with the styling. Maybe I need multi-line? #+begin_src emacs-lisp :lexical no (message (concat "Ahead\n" ;; title (propertize "Wire\n" 'face '(:foreground "#C3E88D")) ;; artist (propertize "The Ideal Copy" 'face '(:foreground "#FF5370")))) ;; album #+end_src #+ATTR_HTML: :width 75% [[file:images/spiffing-up-those-echo-messages/svg-ready-player-colors-multiline.gif]] I felt something was missing. If I could just add the album artwork as a thumbnail... The ideal layout would maybe look something like: #+begin_src +-------+ | | Ahead | image | Wire | | The Ideal Copy +-------+ #+end_src While the text-everywhere nature of Emacs buffers has many advantages, building more involved layouts can have its challenges. But hey, for that simple read-only message we're aiming at, we can certainly get creative without too much trouble. You see, Emacs has native svg support, so we can craft our fancy layout in elisp and tell Emacs to render it for us. While I'm a noob at doing anything in svg from Emacs, adding an image and three labels, really isn't that difficult. #+begin_src emacs-lisp :lexical no (message (let* ((image-width 90) (image-height 90) (text-height 25) (svg (svg-create (frame-pixel-width) image-height))) (svg-embed svg "path/to/thumbnail.png" "image/png" nil :x 0 :y 0 :width image-width :height image-height) (svg-text svg "Ahead" :x (+ image-width 10) :y text-height :fill (face-attribute 'default :foreground)) (svg-text svg "Wire" :x (+ image-width 10) :y (* 2 text-height) :fill "#C3E88D") (svg-text svg "The Ideal Copy" :x (+ image-width 10) :y (* 3 text-height) :fill "#FF5370") (with-temp-buffer (svg-insert-image svg) (buffer-string)))) #+end_src The code is fairly self-explanatory. While there may be an even simpler way (please lemme know), I used a temporary buffer to embed the svg in the propertized text prior to feeding to the handy =message= function. ...and with that, we get a richer display of the current track. #+ATTR_HTML: :width 75% [[file:images/spiffing-up-those-echo-messages/svg-ready-player-colors-image.gif]] While I haven't experimented with other ways of creating multi-column layouts in Emacs (including images), [[https://indieweb.social/@xenodium][I'd love to know]] if there's anything else available besides svg. ** Enjoying these tips?

The goal was simple. Treat opening media files like any other file, that is, open and go. The initial implementation served me well while reviewing lots of tiny audio files I used to practice learning a new language. At this point, I started thinking, could I use ready-player for regular music consumption? The thing is, long ago I had stopped buying music and relied on streamed music from online services. Could I go back to offline? Dusting off my old media collection brought lots of memories as I rediscovered tunes. Having said that, the ready-player experience wasn't quite cutting it for an extended listening experience. I no longer wanted to occasionally peek at media to learn a language. I wanted to load a full music collection. I wanted random access to everything. I wanted Emacs to remember what I was listening to across sessions... While I did [[https://xenodium.com/the-dired-abstraction/][add some pluggable flows]], I still needed additional changes to make the experience more pleasant. While plugging away at my own ready-player's pet peeves, I also collected a handful of feature requests. Let's go over the latest features. ** Seek (f/b binding) - [[https://github.com/xenodium/ready-player/issues/11][feature request]] While not a feature I initially thought ranked highly in priority, I now find myself seeking audio files from time to time. Ready Player delegates all playback to the likes of [[https://mpv.io/][mpv]], [[https://www.videolan.org/vlc/][vlc]], [[https://mplayerhq.hu/design7/news.html][mplayer]], and so on... Up until now, interacting with these utilities merely consisted of feeding a media file path on to the respective process. Command line utilities like =mpv= offer socket communication via =--input-ipc-server= to enable further requests like seeking forward and back. Ready player now supports seeking via mpv. Maybe support for other utilities can be added in the future. If you're on a recent version of ready-player, seeking is automatically enabled if you've got mpv installed and aren't explicitly customizing =ready-player-open-playback-commands=. The default value takes care of things: #+begin_src emacs-lisp :lexical no (defcustom ready-player-open-playback-commands '(("mpv" "--audio-display=no" "--input-ipc-server=<>") ("vlc") ("ffplay") ("mplayer")) "..." :type '(repeat (list string)) :group 'ready-player) #+end_src #+ATTR_HTML: :width 100% [[file:images/seek-and-you-shall-find/seek.webp]] ** Pause/resume (SPC binding) - [[https://github.com/xenodium/ready-player/issues/10][feature request]] Until now, ready-player could only play and stop, so you always had to start playing tracks from the beginning. With =mpv= ipc support now in place, adding pause/resume was a breeze. Like seek, it should just work for ya if =mpv= is on your system and no explicit customization of =ready-player-open-playback-commands=. ** Repeat current file (r binding) - [[https://github.com/xenodium/ready-player/issues/16][feature request]] While repeating current playlist (or directory) was already supported, there was a feature request to enable repeating files. Toggling repeat now cycles through available modes. #+ATTR_HTML: :width 50% [[file:images/seek-and-you-shall-find/repeat.webp]] ** Selective players - [[https://github.com/xenodium/ready-player/issues/13][feature request]] With ready-player delegating to a single utility for either audio or video playback, folks may have a need to specify different utilities for either of these two. While I'm happy for =mpv= to handle both audio and video now have a couple of prepending options. *** Use a predicate function Prepend each utility with either the built-in =ready-player-is-audio-p= or =ready-player-is-video-p= functions, or maybe create your own predicate helper. #+begin_src emacs-lisp :lexical no (setq ready-player-open-playback-commands '((ready-player-is-audio-p "ffplay") (ready-player-is-video-p "mpv"))) #+end_src *** Use an extension list In this example, we delegate mp3 and ogg playback to ffplay and everything else to mpv. #+begin_src emacs-lisp :lexical no (setq ready-player-open-playback-commands '((("mp3" "ogg") "ffplay") ("mpv"))) #+end_src ** Autoplay (a binding) - [[https://github.com/xenodium/ready-player/issues/9][feature request]] Automatically start playing once file opens. No need for user to explicitly request playback. ** Mark in dired (m binding) - [[https://github.com/xenodium/ready-player/issues/8][feature request]] Open a dired buffer and mark the currently played file. #+ATTR_HTML: :width 100% [[file:images/seek-and-you-shall-find/mark.gif]] ** M3u playlists - [[https://github.com/xenodium/ready-player/issues/14][feature request]] While I talked about how [[https://lmno.lol/alvaro/the-dired-abstraction][the dired abstraction]] made basic m3u playlist support possible, it wasn't until recently that I included this experiment in the package itself. In addition, .m3u are now recognized by Emacs and automatically open like any other file: find-file, dired, projectile... ** Load recursive directory With [[https://lmno.lol/alvaro/the-dired-abstraction][the dired abstraction]] at its core, ready player can load any dired buffer. You could do something like: 1. =M-x find-dired RET=. 2. Pick a directory. RET. 3. Type ="-iname \*.mp3 -o -iname \*.ogg -o -iname \*.m4a"= RET. 4. =M-x ready-player-load-dired-buffer= RET. While uber flexible, there's no need to regularly do that, so you can now invoke =M-x ready-player-load-directory= and it will recursively find all media files in it. ** Toggle player view (C-c m m binding) While we can always get back to the player buffer via our favourite buffer-switching mechanism (I like [[https://github.com/abo-abo/swiper][ivy]]'s ivy-switch-buffer), we now have =M-x ready-player-view-player= available for quicker toggle. ** Remember session Playback is now remembered across Emacs sessions. Toggling player view (C-c m m binding) or playback (C-c m SPC binding) starts the last song you were playing on your previous Emacs session. ** Index + searching (/ or C-c m /) We now have automatic indexing, which enables richer searching across your collection, not to mention that random access I was craving. #+ATTR_HTML: :width 100% [[file:images/seek-and-you-shall-find/search.webp]] ** Global bindings Last but not least, you may have noticed a handful of key bindings throughout the post. Single-character bindings all work within a ready-player buffer. Bindings prefixed =C-c m= are now globally available when =ready-player-mode= is turned on. This can be customized via =ready-player-set-global-bindings=. ** Please help make it all self-sustainable If you find this package useful or got the features you wanted, please [[https://github.com/sponsors/xenodium][consider sponsoring the work]].

#+END_EXPORT * [2024-08-16 Fri] The dired abstraction :PROPERTIES: :CUSTOM_ID: the-dired-abstraction :END: I recently [[https://lmno.lol/alvaro/ready-player-mode][wrote about image-mode's next/previous item navigation]], a feature I wanted to bring to [[https://github.com/xenodium/ready-player][ready player mode]]. I was curious to see how =image-mode= resolved next and previous files, so I checked the associated keybinding (n) via [[https://github.com/Wilfred/helpful][helpful-key]] (my preferred alternative to [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Key-Help.html][describe-key]]), and landed on =image-next-file=. While this function only takes care of high-level routing, it led me to =image-mode--next-file=, which is where the actual next/previous file resolution happens: #+begin_src emacs-lisp :lexical no (defun image-mode--next-file (file n) "Go to the next image file in the parent buffer of FILE. This is typically a Dired buffer, but may also be a tar/archive buffer. Return the next image file from that buffer. If N is negative, go to the previous file." ...) #+end_src While =image-mode--next-file='s implementation details are worth [[https://github.com/emacs-mirror/emacs/blob/e4d22abcab60ead179e7d114faa4c2def559cfbb/lisp/image-mode.el#L1264][checking out]], its docstring already highlights the bit I found most interesting: [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Dired.html][dired]]'s involvement in the mix. I'm not sure why I initially found =dired= usage surprising. Buffers are Emacs's backbone. They are the fundamental structures holding the content we work with, whether it’s editing text, reading logs, displaying information, and many others including file management... Dired specializes buffers for this last purpose. While =dired= itself is a powerhouse, at its core it's just an ordered list of files. Given a location within a =dired= buffer, we can use its helpers to find next and previous files. Like =image-mode=, =ready-player= now mirrors this approach (minus tar/archive handling). This got me thinking more about the =dired= abstraction... If it quacks like a duck, and walks like a duck, then it's probably /errrm/ a =dired= buffer. What I actually mean is that associating a =dired= buffer to a =ready-player= buffer effectively attaches a playlist of sorts. It doesn't quite matter how this =dired= buffer was constructed. What's important is that it's recognized as a =dired= buffer, so all relevant helpers remain useful. With =dired= buffers acting as media playlists, we can easily create a directory playlist by merely pointing =dired= to the current directory. This is the default behaviour in =ready-player=. When you open a media file, we attach a =dired= buffer pointing to the current directory. Play next or previous item, and you're effectively moving up and down the associated =dired= buffer. Things get more interesting when we craft =dired= buffers in more creative ways than just supplying a path to a directory. One of my favourite commands is [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Dired-and-Find.html][find-dired]]. It runs the [[https://www.man7.org/linux/man-pages/man1/find.1.html][find]] utility, crafting a =dired= buffer with its results. #+ATTR_HTML: :width 80% [[file:images/the-dired-abstraction/find.png]] For kicks, I added a =ready-player-load-dired-playback-buffer= command to =ready-player=, so we can just load any =dired= buffer, including our newly generated one, courtesy of =find-dired=. With this generated buffer loaded and =ready-player= random playback enabled, we get to see our lucky jumps across find results. #+ATTR_HTML: :width 100% [[file:images/the-dired-abstraction/find-random.gif]] At this point I thought "this is prolly as far as I'll take things"... =ready-player= was born to address quick access to media, typically from =dired= itself. For deep playlist handling, there are many other Emacs media players. The thing is, with my newly found reusable =dired= abstraction, a rough [[https://en.wikipedia.org/wiki/M3U][m3u]] playlist experiment didn't seem that far-fetched at all. I'd need to read an =m3u= file and generate a =dired= buffer. I knew nothing about m3u's, other than being text files including media paths, along with optional metadata. I figured /minimal/ m3u reading support shouldn't be too difficult. If we are to create a playlist including the first three album tracks from the artist above, it'd look something like this: #+begin_src #EXTM3U #EXTINF:-1,George Benson - Dance /absolute/path/to/Music/George Benson/Body Talk/01 Dance.mp3 #EXTINF:-1,George Benson - When Love Has Grown /absolute/path/to/Music/George Benson/Body Talk/02 When Love Has Grown.mp3 #EXTINF:-1,George Benson - Plum /absolute/path/to/Music/George Benson/Body Talk/03 Plum.mp3 #EXTINF:-1,George Benson - So What /absolute/path/to/Music/George Benson/Original Album Classics/1-01 So What.mp3 #EXTINF:-1,George Benson - The Gentle Rain /absolute/path/to/Music/George Benson/Original Album Classics/1-02 The Gentle Rain (From the Film, _The Gentle Rain_).mp3 #EXTINF:-1,George Benson - All Clear /absolute/path/to/Music/George Benson/Original Album Classics/1-03 All Clear.mp3 #EXTINF:-1,George Benson - Footin' It /absolute/path/to/Music/George Benson/The Shape Of Things To Come/01 Footin' It.mp3 #EXTINF:-1,George Benson - Face It Boy It's Over /absolute/path/to/Music/George Benson/The Shape Of Things To Come/02 Face It Boy It's Over.mp3 #EXTINF:-1,George Benson - Shape Of Things To Come /absolute/path/to/Music/George Benson/The Shape Of Things To Come/03 Shape Of Things To Come.mp3 #+end_src A crude function to extract file paths into a list would look something like the following: #+begin_src emacs-lisp (defun ready-player--media-at-m3u-file (m3u-path) "Read m3u playlist at M3U-PATH and return files." (with-temp-buffer (insert-file-contents m3u-path) (let ((files)) (while (re-search-forward (rx bol (not (any "#" space)) (zero-or-more (not (any "\n"))) eol) nil t) (when (file-exists-p (match-string 0)) (push (match-string 0) files))) (nreverse files)))) #+end_src Feeding our m3u file to our new function conveniently returns a list of found files: #+begin_src emacs-lisp ("/absolute/path/to/Music/George Benson/Body Talk/01 Dance.mp3" "/absolute/path/to/Music/George Benson/Body Talk/02 When Love Has Grown.mp3" "/absolute/path/to/Music/George Benson/Body Talk/03 Plum.mp3" "/absolute/path/to/Music/George Benson/Original Album Classics/1-01 So What.mp3" "/absolute/path/to/Music/George Benson/Original Album Classics/1-02 The Gentle Rain (From the Film, _The Gentle Rain_).mp3" "/absolute/path/to/Music/George Benson/Original Album Classics/1-03 All Clear.mp3" "/absolute/path/to/Music/George Benson/The Shape Of Things To Come/01 Footin' It.mp3" "/absolute/path/to/Music/George Benson/The Shape Of Things To Come/02 Face It Boy It's Over.mp3" "/absolute/path/to/Music/George Benson/The Shape Of Things To Come/03 Shape Of Things To Come.mp3") #+end_src Next we need to create a dired buffer from a list of files. This is where I thought things would get trickier, but I was pleasantly surprised. The =dired= docstring had the answer: #+begin_src emacs-lisp :lexical no (defun dired (dirname &optional switches) "... If DIRNAME is a cons, its first element is taken as the directory name and the rest as an explicit list of files to make directory entries for. In this case, SWITCHES are applied to each of the files separately, and therefore switches that control the order of the files in the produced listing have no effect. ..." ...) #+end_src With that in mind, this is all it takes: #+begin_src emacs-lisp :lexical no (let ((default-directory "/absolute/path/to/Music/George Benson")) (dired '("*My fancy m3u list*" "Body Talk/01 Dance.mp3" "Body Talk/02 When Love Has Grown.mp3" "Body Talk/03 Plum.mp3" "Original Album Classics/1-01 So What.mp3" "Original Album Classics/1-02 The Gentle Rain (From the Film, _The Gentle Rain_).mp3" "Original Album Classics/1-03 All Clear.mp3" "The Shape Of Things To Come/01 Footin' It.mp3" "The Shape Of Things To Come/02 Face It Boy It's Over.mp3" "The Shape Of Things To Come/03 Shape Of Things To Come.mp3"))) #+end_src Here's the =dired= buffer to prove it: #+ATTR_HTML: :width 100% [[file:images/the-dired-abstraction/playlist.png]] We now have all the pieces. We can wire them up in a =ready-player-load-m3u-playlist= function. From the previous snippet, you'd notice all file paths are relative to default-directory. While in the following snippet I use =try-completion= to find the longest common substring amongst the paths, I wonder if there's a more appropriate built-in function for this? [[https://indieweb.social/@xenodium][I'd love to hear]]. #+begin_src emacs-lisp (defun ready-player-load-m3u-playlist () "Load an .m3u playlist." (interactive) (let* ((m3u-path (read-file-name "find m3u: " nil nil t nil (lambda (name) (or (string-match "\\.m3u\\'" name) (file-directory-p name))))) (media-files (if (string-match "\\.m3u\\'" m3u-path) (ready-player--media-at-m3u-file m3u-path) (error "Not a .m3u file"))) (default-directory (file-name-directory (try-completion "" media-files))) (m3u-fname (file-name-nondirectory m3u-path)) (dired-buffer-name (format "*%s*" m3u-fname)) (dired-buffer (dired (append (list dired-buffer-name) (mapcar (lambda (path) (file-relative-name path default-directory)) media-files))))) (ready-player-load-dired-playback-buffer dired-buffer))) #+end_src We're good to go now!

While =dired= is often used to manage files within a directory, its magic also extends to =dired= buffers crafted in more creative ways. =find-dired= and =find-grep-dired= are my two favourite built-ins. Are there other ones you like? [[https://indieweb.social/@xenodium][Do tell]]. Not long ago, I added =ready-player-load-dired-playback-buffer= to ready-player, but =ready-player-load-m3u-playlist= remains a local experiment (for now anyway).

I was wrong. There's a better way. So, I totally missed the macOS native emoji picker is actually supported out of the box 😭. Thanks to redditor [[https://www.reddit.com/user/hrabannixlisp/][u/hrabannixlisp]] who [[https://www.reddit.com/r/emacs/comments/1ec5t4j/comment/ley1j59][pointed me in the right direction]]. =ns-do-show-character-palette= is bound to =C-s-SPC= by default, which didn't work for me as I use =(setq mac-command-modifier 'meta)=, that is, ⌘ as meta modifier. While I won't be giving up =(setq mac-command-modifier 'meta)=, I can certainly use =ns-do-show-character-palette= via =M-x= or a different binding. Thank you =u/hrabannixlisp=! ** Read on for how I went about it the long convoluted way 🤷‍♂️ A couple of years ago, I was delighted to discover [[https://lmno.lol/alvaro/emacs-freebie-macos-emoji-picker][a macOS freebie for us Emacs users]]. Newer Macbook models started shipping with a globe/🌐 key, which summons the macOS native emoji picker. Pressing this key in Emacs works as you'd expect (no config required 🎉). While I seldom use emojis, the globe key worked great for me until I started using an external keyboard, which didn't have this magical key. The potential solutions I came across suggest either reprogramming the keyboard or using the likes of [[https://karabiner-elements.pqrs.org/][Karabiner-Elements]] to map other keys to an alternate shortcut: =Ctrl-⌘-SPC=. As far as I can tell, this is the only other available shortcut (please reach out if otherwise). Not a great option (it conflicts with Emacs's =mark-sexp=). Not that I'd be super keen to lose this mark command, but even unbinding doesn't seem of much help. While we have Emacs packages available for different emoji-picking experiences, I was keen on maintaining that native experience I enjoyed before. I nearly gave up on the matter until I remembered we have at least one more tool in the Emacs toolbox: [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Modules.html][dynamic modules]]. Thanks to Valeriy Savchenko's [[https://github.com/SavchenkoValeriy/emacs-swift-module][emacs-swift-module]], we can leverage Swift to integrate native macOS experiences. With that in mind, I set out to find the relevant macOS API, which turned out to be a lovely one-liner: #+begin_src swift NSApp.orderFrontCharacterPalette(nil) #+end_src Let's bring it into Emacs via =emacs-swift-module='s infrastructure: #+begin_src swift try env.defun( "macos-module--show-emoji-picker", with: "Show emoji picker (macOS module implementation)." ) { (env: Environment) in NSApp.orderFrontCharacterPalette(nil) } #+end_src In theory, this is all we need. We can =M-x eval-expression= =(macos-module--show-emoji-picker)= and the picker simply pops up. I haven't worked out how define an interactive command from =emacs-swift-module= just yet, so for now I'll just wrap with a little elisp: #+begin_src emacs-lisp :lexical no (defun macos-show-emoji-picker () "Show macOS emoji picker." (interactive) (macos-module--show-emoji-picker)) #+end_src And with that, we got our native macoOS emoji picker back at our fingertips: #+ATTR_HTML: :width 100% [[file:images/emacs-macos-native-emoji-picker-revisited/hearts3.webp]] While the dedicated globe key /just worked/ without configuration, it required newer hardware. This new approach works on older Macbooks too. Since it's an interactive command, you can optionally bind to your preferred keys. Having said all that, you may have noticed a brief lag during insertion. I haven't worked out the source, but since I rarely use emojis, this will have to do for now. If you have a better macOS alternative working on external keyboards, [[https://indieweb.social/@xenodium][I'd love to hear about it]]!

A live playground of sorts, where almost everything is up for grabs. You can inspect and tweak behaviour of just about anything to your liking. While the compounding benefits of using your favourite Emacs utilities are evident over time, learning elisp takes the compounding effect to another level. It empowers you to have those aha moments like "if I could just wire this awesome utility with that other one, it'd be perfect for me" and enable you to act on it. Take, for example, [[https://github.com/wolray/symbol-overlay][symbol-overlay]] and [[https://github.com/magnars/multiple-cursors.el][multiple-cursors]]. Two Emacs packages I've been using for years. The first one is a feature you've likely experienced on your favourite IDE or editor without thinking too much about it. Placing your editor cursor on a variable automatically highlights its usages. It's one of those lovely features with zero learning demands. #+ATTR_HTML: :width 80% [[file:images/its-all-up-for-grabs-and-it-compounds/overlay-symbol.gif]] The second utility, [[https://github.com/magnars/multiple-cursors.el][multiple-cursors]], does demand some learning but can be so fun to use once you get the hang of it.

"if I could just get =symbol-overlay= to tell =multiple-cursors= where to place my cursors, it'd be just perfect for me". I've been wanting this tweak for some time. Today's the day I finally act on it. I had no idea how to go about it, but opening =symbol-overlay.el= (via =M-x find-library symbol-overlay=) and browsing through all functions (via imenu) yields the first piece I needed: =symbol-overlay-get-list=. #+ATTR_HTML: :width 80% [[file:images/its-all-up-for-grabs-and-it-compounds/imenu.png]] #+begin_src emacs-lisp :lexical no (defun symbol-overlay-get-list (dir &optional symbol exclude) "Get all highlighted overlays in the buffer.

Dired has [[https://xenodium.com/emacs-git-rename-courtesy-of-dired/][magical things like wdired]]. But this post isn't so much about dired and more about the occasional need to peek at media files (images, audio, and video) from Emacs (including dired). To view images in Emacs, there's [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Image-Mode.html][image mode]], a fantastic major mode for taking a quick look without leaving your editor. Image mode strikes a great balance. You can get in quickly and out. The =q= keyboard binding is fabulous for bailing out. While viewing an image, you may quickly open the previous/next one by using =n= and =p= keyboard binding. For me, this is just about all I need within my text editor. For anything else, I resort to my favorite image viewing app (macOS's Preview). For audio and video, we aren't as lucky with Emacs built-in features (even for a quick peek). While Emacs faithfully opens the files, it's not realistically practical for my typical needs. #+ATTR_HTML: :width 70% [[file:images/ready-player-mode/no-handling.png]] There's a convenient package aptly named [[https://github.com/jpkotta/openwith][openwith]], which automatically opens specific files in an external app. This isn't just for media files, but anything really. It works well with office docs, for example. While I've used it for quite some time, I found always bouncing to an external app for peeking at audio/video somewhat suboptimal. While a [[https://www.reddit.com/r/emacs/comments/1dtnjy7/is_there_imageview_but_for_audio][reddit post]] yielded some handy options, none were in the same spirit as image mode. Having said that, I did come across [[https://github.com/xFA25E/mediainfo-mode][mediainfo-mode]] on my search, which is pretty neat for viewing media metadata quickly. Bonus points for =q= keyboard binding to exit and =mediainfo-mode-open= command to open with an external app. There may be other packages out there (I'd love to hear about them), though most seemed to focus on listening to music (and playlist management), which is a different flow from what I'm after. ** Ready player mode enters the chat With all that, I had no choice (I kid of course) but to go and throw some lines of elisp together and see if I could get to my ideal media experience, and so [[https://github.com/xenodium/ready-player][ready player mode]] was born... #+ATTR_HTML: :width 80% [[file:images/ready-player-mode/ready-player.png]] #+ATTR_HTML: :width 100% [[file:images/ready-player-mode/video-player.png]] As core features, =ready-player-mode= has two buttons: one to play from within Emacs and one to open media in the preferred external app. You can =TAB= your way to the buttons. =RET= or =click= actions the buttons, in addition to the =SPC= keyboard binding to toggle playback. Like image mode, =ready-player-mode= offers =n/p= navigation to open the next/previous media file in the current directory. =ready-player-mode= attempts to display basic metadata if possible, courtesy of =ffprobe= and =ffmpeg=. You'll need these installed on your system if you want the optional metadata. Playback is handled by your favourite command line utility. =ready-player-mode= will try to use either [[https://mpv.io/][mpv]], [[https://www.videolan.org/vlc/][vlc]], [[https://ffmpeg.org/ffplay.html][ffplay]], or [[https://mplayerhq.hu/design7/news.html][mplayer]] (in that order), but you can customize that. =ready-player-mode= is available on [[https://github.com/xenodium/ready-player][GitHub]] if you're keen to check it out. Keep in mind this is a brand new package (a day old!), so it may need some improvements. If you do give it a try, [[https://indieweb.social/@xenodium][I'd love to hear]] how you got on.

My MacBook's trackpad is great for just kicking back to read and scroll through text. There are brief times, however, when that keyboard-driven muscle memory overlaps my mouse usage, resulting in a buffer catastrophe. I joke of course. What I'm actually referring to is nothing more than a slight annoyance. There are times when I inadvertently trigger == or == events (because I happen to hold =Ctrl= down while triggering scrolling events). This results in buffer font size quickly changing to either really large or super small, depending on whether I was scrolling up or down at the time. The snafu is further exacerbated by inertial scrolling on trackpads. Go ahead and press the Ctrl key while your buffer is carrying some of that inertia. The font size is affected just the same, even though there was no explicit physical/touching activity on the trackpad at the time. #+ATTR_HTML: :width 80% [[file:images/hey-mouse-dont-mess-with-my-emacs-font-size/scroll-reduces-font-size.gif]] While this behaviour was a little annoying, I would typically just reopen the file via =C-x C-v RET= (aka =find-alternate-file=), which would reset the font size as a convenient side-effect. Now, you may wonder if reopening the file would also forget the point/cursor position, but that's not an issue if you've got the handy built-in [[https://www.emacswiki.org/emacs/SavePlace][save-place-mode]] turned on (highly recommended). Ok and all, but this is a second-class workaround at best. What I really wanted is for the mouse/trackpad to stop messing with my font size. Lucky for me, I bumped into a [[https://indieweb.social/@goldayan@clj.social/112195984778424216][simple solution]] shared by [[https://indieweb.social/@shanecelis@mastodon.gamedev.place][Shane Celis]] and [[https://indieweb.social/@goldayan@clj.social][Thanga Ayyanar]].

You turn a directory representation into an editable buffer and you can do some magic. By magic, I mean you can apply your favourite text-editing commands to a directory and do some file management. Take, for example, batch-renaming. Turn =wdired= on via =dired-toggle-read-only=, use something like Magnar's [[https://github.com/magnars/multiple-cursors.el][multiple-cursors]] (or built-in [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Keyboard-Macros.html][keyboard macros]]) and commit via =wdired-finish-edit= (using the often-familar =C-c C-c= binding).

Pretty magical. #+ATTR_HTML: :width 95% [[file:images/emacs-git-rename-courtesy-of-dired/wdired.gif]] One downside (or so I thought) is that wdired didn't automagically also take care of git renames for me, you know [[https://xenodium.com/emacs-dwim-do-what-i-mean/][DWIM-style]].

I started off by setting a breakpoint on =wdired-finish-edit= via edebug (see [[https://xenodium.com/inline-previous-result-and-why-you-should-edebug/][why this util is awesome]]). I wanted to see what =wdired-finish-edit= did under the hood, which led me to =dired-rename-file=.

One =setq= later... #+begin_src emacs-lisp :lexical no (setq dired-vc-rename-file t) #+end_src ...and boom! From now on, renaming from dired does exactly what you would expect.

I didn't have all the right ingredients for the full-blown salad at home, so I set out to experiment with the dressing's punchy flavours. While I've gone a little rogue here, I mean no disrespect to the faithful recipe and all its glory. Luckily, I did have fish sauce at home, which I considered the core ingredient, and made do with everything else I could find. This is where I landed: - 2 cloves of garlic - Thai chillies to taste (improvised with chilli flakes) - 2 tablespoons of fish sauce - 1 tablespoons of palm sugar (improvised with honey) - 2 limes squeezed (improvised with lemon) - 1 tablespoon of dried shrimp (didn't have any) - 1 small plum tomato (I used 2 of those bite-size ones) Using my trusty mortar and pestle, I ground and crushed the garlic, chilli flakes, and tomato, forming a paste of sorts. Then added the remaining liquids (fish sauce, honey and lemon) diluting the paste. - 2 tablespoons of roasted peanuts (roasted some cashews) Most recipes seem to suggest using peanuts, though my local Thai restaurant uses cashews. Luckily I had cashews at home, so I'm copied my local. Roasted them on pan for a few minutes. As you can imagine, I didn't just have a green papaya laying around at home, so I experimented with other crunchy veggies.

Skip to the [[id:cloudflare-worker-hello-world-setup][setup]] section. ** A little background The vast majority of my software development experience has been centered around client-side software. The few times I've needed a server-side component for a hobby project, I've historically provisioned a linux [[https://en.wikipedia.org/wiki/Virtual_machine][virtual machine]] somewhere and ran whatever services I needed. I have to admit though, I don't enjoy the provisioning process, configuration, maintenance, upgrades, database admin, etc. which take time away from the part I enjoy more: building and experimenting with features. While [[https://en.wikipedia.org/wiki/Containerization_(computing)][containers]] have made things somewhat simpler, much of the maintenance tradeoffs remain. These days, the server-managing overhead has been greatly reduced by "[[https://en.wikipedia.org/wiki/Serverless_computing][serverless]]" solutions. Odd terminology for a server offering, but I digress. It more or less refers to removing most of that additional responsibility that comes with managing your own servers and enabling you to focus on building your business logic. Having said that, I've typically shied away from these services, with the possibly irrational fear of vendor lock-in. The thing is, if most of my potential server-side needs merely require an entry point (where I could route/handle incoming requests) and possibly some persistence (maybe a database), I should be able to abstract these things away and build server-side logic against portable abstractions. With that in place, maybe there's little vendor lock-in to worry about? Who knows, the devil's in the detail. If I keep shying away from these services, I'll never know, so maybe I should try some and see. ** Let's try Cloudflare Workers There are no shortages of serverless options offering [[https://en.wikipedia.org/wiki/Function_as_a_service][functions as a service]].

You can access it via the URL that looks something like https://todos.somewhere.workers.dev #+ATTR_HTML: :width 70% [[file:images/a-cloudflare-workers-primer-hello-world/hello-dark.png]] This is great and all, but we want to build something with this new worker, so let's set up our local development environment... ** Prerequisites You'll need [[https://nodejs.org/][node.js]] installed on your machine. I happen to be on macOS, so I installed node via [[https://brew.sh/][Homebrew]]. #+begin_src sh brew install node #+end_src ** Create a new node project We want to start with a bare bones node project, so let's do just that. #+begin_src sh mkdir HelloCloudflareWorker cd HelloCloudflareWorker npm init -y #+end_src ** Install TypeScript (compiler) I like some guardrails when targetting Javascript, so I'll use the [[https://www.typescriptlang.org][TypeScript]] compiler in this project. Let's install it. #+begin_src sh npm install --save-dev typescript npx tsc --init #+end_src ** Install Cloudflare Typescript types To have Cloudflare types information accessible to the TypeScript compiler, we'll need to install that too. #+begin_src sh npm install --save-dev @cloudflare/workers-types #+end_src ** Install Wrangler (Cloudflare tooling) To manage your worker from the command-line, you'll need Cloudflare's [[https://developers.cloudflare.com/workers/wrangler/][wrangler]] tool. Let's install it. #+begin_src sh npm install --save-dev wrangler #+end_src ** Point Wrangler to our worker We're done installing things now. Let's point wrangler to our new worker by creating its config file. =wrangler.toml= #+begin_src sh name = "todos" main = "worker/worker.ts" #+end_src ** Worker entry point By default, the worker we created using Cloudflare's dash has the following entry point: #+begin_src js export default { async fetch(request, env, ctx) { return new Response( 'Hello World!'): } } #+end_src However, this isn't yet included in our development environment. We need to write our first bit of code. You may have noticed our =wrangler.toml= is pointing to the main entry point (=worker/worker.ts=) and this file doesn't exist yet. Let's create it, though be sure to also create its owning directory: #+begin_src sh mkdir worker #+end_src Now we can create our very own =worker/worker.ts=. Let's make the first change that shapes worker to our liking. Rather than just printing "Hello World", let's style things up using our [[https://en.wikipedia.org/wiki/Cowsay][cow friend]]. We'll create =worker/worker.ts= and include the spiffed up message. =worker/worker.ts= #+begin_src js import { Env, ExecutionContext } from '@cloudflare/workers-types'; export default { async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise { let defaultResponse = ` o______________o | Hello World! | o--------------o \\ ^__^ \\ (oo)\_______ (__)\\ )\\/\\ ||----w | || ||` return new Response(defaultResponse); } }; #+end_src It's worth mentioning the import statement, since it brings Cloudflare's type information for both =Env= and =ExecutionContext=. ** Running worker locally Okay, we now have our =worker/worker.ts= code ready to go. Let's run it locally. For that we use the wrangler utility. #+begin_src sh npx wrangler dev #+end_src #+ATTR_HTML: :width 90% [[file:images/a-cloudflare-workers-primer-hello-world/dev.png]] With that, you'll notice the worker is now running locally and waiting to be visited at http://localhost:8787. #+ATTR_HTML: :width 70% [[file:images/a-cloudflare-workers-primer-hello-world/moo.png]] ** Deploying worker When we first created the worker via https://dash.cloudflare.com, it automatically deployed to https://todos.somewhere.workers.dev. But our mods only ran locally. Let's deploy, again with the wrangler utility. #+begin_src sh npx wrangler deploy #+end_src #+ATTR_HTML: :width 70% [[file:images/a-cloudflare-workers-primer-hello-world/deploying.png]] We're good to go. Let's point our browser to the worker's public location. #+ATTR_HTML: :width 70% [[file:images/a-cloudflare-workers-primer-hello-world/deployed.png]] ...and with that, we have a functional Cloudflare Worker and a local development environment to shape things up however we'd like. What would you use the Worker for? Gave this primer a try?

ChatGPT's request-response nature maps fairly well to a shell's mode of interaction. In the past, I've also talked about [[https://xenodium.com/yasnippet-in-emacs-eshell/][blurring the lines between shell and editor]]. That is, using Emacs as your shell ([[https://www.masteringemacs.org/article/complete-guide-mastering-eshell][eshell]] being my favourite) enables compounding goodies from both shell and editor when both are used from the same app. Keeping interactions within the same app also cuts down on some of that friction that comes with context switching between your text editor and the browser for [[https://en.wikipedia.org/wiki/Large_language_model][llm]] things. Today, my interactions with llms typically consists of copying and pasting details from other Emacs buffers, crafting a query, and finally submitting by pressing enter (RET) from a shell like [[https://github.com/xenodium/chatgpt-shell][chatgpt-shell]]. #+ATTR_HTML: :width 90% [[file:images/a-chatgpt-shell-compose-ux-experiment/shell-find-bug.gif]] With the entire interaction happening from Emacs, we're already cutting a fair amount of friction... But we can do better, specially when copying, pasting, and crafting those multi-line queries (you don't want to prematurely submit those shell queries by inadvertently pressing RET when you want a newline). ** chatgpt-shell-prompt-compose This is where =chatgpt-shell-prompt-compose= comes in, an opinionated experiment bringing some of my favourite "compose" features over from the likes of [[https://github.com/magit][magit]] commit buffers, [[https://www.gnu.org/software/emacs/manual/html_node/org/Using-capture.html][org capture]], [[https://www.djcbsoftware.nl/code/mu/mu4e/][mu4e]] compose, and so on... You can bring a compose buffer up by invoking =M-x chatgpt-shell-prompt-compose=. From there, you can both craft and send your queries. If you're a magit fan, the process should feel fairly familiar with crafting a git commit message by editing away and quickly committing (via =C-c C-c= binding). Similarly, you can also abort with the familiar =C-c C-k= binding. #+ATTR_HTML: :width 90% [[file:images/a-chatgpt-shell-compose-ux-experiment/10k.gif]] I use this compose utility often enough that I bound it to =C-c C-e=, though this may not be your cup of tea (needs overriding other mode maps). #+begin_src emacs-lisp (use-package chatgpt-shell :commands (chatgpt-shell chatgpt-shell-prompt-compose) :bind (("C-c C-e" . chatgpt-shell-prompt-compose) :map org-mode-map ("C-c C-e" . chatgpt-shell-prompt-compose) :map eshell-mode-map ("C-c C-e" . chatgpt-shell-prompt-compose) :map mu4e-compose-mode-map ("C-c C-e" . chatgpt-shell-prompt-compose) :map emacs-lisp-mode-map ("C-c C-e" . chatgpt-shell-prompt-compose))) #+end_src While the compose buffer displays a single query/response at a time, it also follows on from previous requests. You can press =r= to reply and continue the conversation. #+ATTR_HTML: :width 90% [[file:images/a-chatgpt-shell-compose-ux-experiment/marathon.gif]] The compose buffer is fairly stateless and mostly serves as viewport over the last query in the shell itself. If you invoke =chatgpt-shell-prompt-compose= with a prefix (ie. C-u), it wipes the shell history. You can do it from the compose buffer itself, if you forgot to prior to launching. You can also use the =o= binding to jump to the "other buffer" (the shell carrying the conversation history). #+ATTR_HTML: :width 90% [[file:images/a-chatgpt-shell-compose-ux-experiment/other.gif]] If using the =r= and =o= bindings in a compose buffer sounds a little strange, fear not. The compose buffer is writeable while crafting queries, thus you can safely insert any character. Once a query is submitted (via =C-c C-c=), the buffer automatically becomes read-only, and thus unlocking single-character bindings. Another magit commit favorite of mine is using the =M-p= or =M-n= bindings to insert previous messages via =git-commit-prev-message= or =git-commit-next-message=. With that in mind, I also brought =M-p= and =M-n= over to the editable compose buffer. #+ATTR_HTML: :width 90% [[file:images/a-chatgpt-shell-compose-ux-experiment/previous-next-history.gif]] If cycling isn't efficient enough, you can also use the typical =M-r= binding to search and insert from history. #+ATTR_HTML: :width 90% [[file:images/a-chatgpt-shell-compose-ux-experiment/search-history.png]] Now, getting back to removing some of that copy-pasting friction... Selecting text in any buffer and invoking =M-x chatgpt-shell-prompt-compose= (or =C-c C-e= in my case) automatically pastes the region into the compose buffer. You get to tweak your query before submitting (via that familiar =C-c C-c=), in a more flexible buffer (compared to a shell). /Note: You can also invoke the compose command with a region as many times as you'd like. Each region is sent to the compose buffer, so you can craft more involved queries before submission./ #+ATTR_HTML: :width 90% [[file:images/a-chatgpt-shell-compose-ux-experiment/find-and-fix-bug.gif]] While I typically prefer short query responses (using diffs like the example above), I sometimes want full snippets as follow-ups. I found myself typing /"show entire snippet"/ often enough, that I now use one of those single-character bindings (=e=) for this purpose. #+ATTR_HTML: :width 90% [[file:images/a-chatgpt-shell-compose-ux-experiment/show-entire-snippet.gif]] ** Compose bindings I've showcased most of the compose key bindings, here's the whole lot (so far anyway), which you can also view from =chatgpt-shell-prompt-compose='s documentation. *** Editing - =C-c C-c= to send the buffer query. - =C-c C-k= to cancel compose buffer. - =M-r= search through history. - =M-p= cycle through previous item in history. - =M-n= cycle through next item in history. *** Read-only - =C-c C-c= After sending offers to abort query in-progress. - =q= Exits the read-only buffer. - =g= Refresh (re-send the query). Useful to retry on disconnects. - =n= Jump to next source block. - =p= Jump to next previous block. - =r= Reply to follow-up with additional questions. - =e= Send "Show entire snippet" query. - =o= Jump to other buffer (ie. the shell itself). - =C-M-h= Mark block at point. ** Buyer beware: it's all pretty experimental When I started playing with the compose buffer idea, I wasn't too sure whether or not its usage would stick, so I basically hacked =chatgpt-shell-prompt-compose= to pieces. A cheap prototype of sorts to validate the idea before fully committing to a more involved solution. I'll eventually rewrite =chatgpt-shell-prompt-compose= as either a major or minor mode if there's enough interest. For now, I'll continue using as is to validate its usefulness. If you give =chatgpt-shell-prompt-compose= a try, I'd love to hear your feedback ([[https://indieweb.social/@xenodium][Mastodon]] / [[https://twitter.com/xenodium][Twitter]] / [[https://www.reddit.com/user/xenodium][Reddit]] / [[mailto:me__AT__xenodium.com][Email]]). /Enjoying this content?

Maybe dump a bunch of links into an org file and use that as a quick and dirty bookmark manager. We'll start with a flat list plus fuzzy searching and see how far that gets us. The org file would look a little something like this: #+CAPTION: bookmarks.org #+begin_src org My bookmarks - [[https://lobste.rs/t/emacs][Emacs editor (Lobsters)]] - [[https://emacs.stackexchange.com][Emacs Stack Exchange]] - [[https://www.reddit.com/r/emacs][Emacs subreddit]] - [[https://emacs.ch][Emacs.ch (Mastodon)]] - [[https://www.emacswiki.org][EmacsWiki]] - [[https://planet.emacslife.com/][Planet Emacslife]] #+end_src Next we need fuzzy searching, but first let's write a little elisp to extract all links from the org file: #+begin_src emacs-lisp :lexical no (require 'org-element) (require 'seq) (defun browser-bookmarks (org-file) "Return all links from ORG-FILE." (with-temp-buffer (let (links) (insert-file-contents org-file) (org-mode) (org-element-map (org-element-parse-buffer) 'link (lambda (link) (let* ((raw-link (org-element-property :raw-link link)) (content (org-element-contents link)) (title (substring-no-properties (or (seq-first content) raw-link)))) (push (concat title "\n" (propertize raw-link 'face 'whitespace-space) "\n") links))) nil nil 'link) (seq-sort 'string-greaterp links)))) #+end_src The snippet uses =org-element= to iterate over links to collect/return them in a list. We join both the title and url, so searching can match either of these values. We also add a little formatting (new lines/face) to spiff things up. #+begin_src emacs-lisp :results value code (browser-bookmarks "/private/tmp/bookmarks.org") #+end_src #+RESULTS: #+begin_src emacs-lisp (#("Planet Emacslife\nhttps://planet.emacslife.com/\n" 17 46 (face whitespace-space)) #("EmacsWiki\nhttps://www.emacswiki.org\n" 10 35 (face whitespace-space)) #("Emacs.ch (Mastodon)\nhttps://emacs.ch\n" 20 36 (face whitespace-space)) #("Emacs (Stack Exchange)\nhttps://emacs.stackexchange.com\n" 23 54 (face whitespace-space)) #("Emacs (Reddit)\nhttps://www.reddit.com/r/emacs\n" 15 45 (face whitespace-space)) #("Emacs (Lobsters)\nhttps://lobste.rs/t/emacs\n" 17 42 (face whitespace-space))) #+end_src We can now feed our list to our preferred narrowing framework (ivy, helm, ido, vertico) and use it to quickly select a bookmark. In the past, I've [[https://xenodium.com/emacs-utilities-for-your-os/][used the likes of ivy-read]] directly, though have since adopted the humble but mighty =completing-read= which hooks up to any of the above frameworks. With that in mind, let's use =completing-read= to make a selection and split the text to extract the corresponding URL. Feed it to =browse-url=, and you got your preferred browser opening your bookmark. #+begin_src emacs-lisp :lexical no (defun open-bookmark () (interactive) (browse-url (seq-elt (split-string (completing-read "Open: " (browser-bookmarks "/private/tmp/bookmarks.org")) "\n") 1))) #+end_src I remain a happy ivy user, so we can see its fuzzy searching in action. #+ATTR_HTML: :width 100% [[file:images/building-your-own-bookmark-launcher/emacs-bookmark.gif]] At this point, we now have our bookmark-launching Emacs utility. It's only an =M-x open-bookmark= command away, but we want to make it accessible from anywhere in our operating system, in my case macOS. Let's enable launching from the command line, though before we do that, let's craft a dedicated frame for this purpose. #+begin_src emacs-lisp :lexical no (defmacro present (&rest body) "Create a buffer with BUFFER-NAME and eval BODY in a basic frame."

While I don't typically resort to macros, we get a little syntatic sugar here, so we can invoke like so: #+begin_src emacs-lisp :lexical no (defun present-open-bookmark-frame () (present (browse-url (seq-elt (split-string (completing-read "Open: " (browser-bookmarks "/private/tmp/bookmarks.org")) "\n") 1)))) #+end_src Wrapping our one-liner with the =present-open-bookmark-frame= function enables us to easily invoke from the command line, with something like #+begin_src sh emacsclient -ne "(present-open-bookmark-frame)" #+end_src #+ATTR_HTML: :width 100% [[file:images/building-your-own-bookmark-launcher/command.gif]] Now that we can easily invoke from the command line, we have the flexibility to summon from anywhere.

A live playground of sorts, where almost everything is up for grabs at runtime. Throw some elisp at it, and you can customize or extend almost anything to your heart's content. I say almost, as there's a comparatively small native core, that would typically require recompiling if you wanted to make further (native) mods. But that isn't entirely true. [[https://www.masteringemacs.org/article/whats-new-in-emacs-25-1][Emacs 25]] enabled us to further extend things by loading native [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Modules.html][dynamic modules]], back in 2016. Most of my Emacs-bending adventures have been powered by elisp, primarily on macOS. I also happen to have an iOS dev background, so when [[https://github.com/SavchenkoValeriy][Valeriy Savchenko]] [[https://www.reddit.com/r/emacs/comments/wemj1z/writing_emacs_dynamic_modules_in_swift/][announced]] his project bringing [[https://github.com/SavchenkoValeriy/emacs-swift-module][Emacs dynamic modules powered by Swift]], I added it to my never-ending list of things to try out. Fast-forward to a year later, and [[https://github.com/roife][Roife]]'s [[https://www.reddit.com/r/emacs/comments/17vrmrk/emt_emacs_macos_tokenizer_for_enhanced_cjk_word/][introduction]] to [[https://github.com/roife/emt][emt]] finally gave me that much-needed nudge to give [[https://github.com/SavchenkoValeriy/emacs-swift-module][emacs-swift-module]] a try. While I wish I had done it earlier, I also wish [[https://github.com/SavchenkoValeriy/emacs-swift-module][emacs-swift-module]] had gotten more visibility. Native extensions written in Swift can open up some some neat integrations using native macOS UX/APIs. While I'm new to Savchenko's [[https://github.com/SavchenkoValeriy/emacs-swift-module][emacs-swift-module]], the project has [[https://savchenkovaleriy.github.io/emacs-swift-module/documentation/emacsswiftmodule/][wonderful documentation]]. It quickly got me on my way to build an experimental dynamic module introducing a native context menu for sharing files from my beloved editor. #+ATTR_HTML: :width 90% [[file:images/native-emacsmacos-ux-integrations-via-swift-modules/emacs-share.webp]] Most of the elisp/native bridging magic happens with fairly little Swift code: #+begin_src swift try env.defun( "macos-module--share", with: """ Share files in ARG1.

That is, [[https://xenodium.com/emacs-dwim-do-what-i-mean/][do what I mean (DWIM) style]]. If there's a file associated with current buffer, share it.

Needless to say, I shamelessly enjoy gobbling them too! #+CAPTION: my smash burger #+ATTR_HTML: :width 60% [[file:images/how-i-smash-burgers/burger-cut.png]] I'll share details on how I smash my burgers, but here's a quick ingredient list, if that's all you need. - Mince beef (20%-30% fat). - Streaky bacon. - Brioche burger buns. - American cheese slices (cheddar individual slices work too). - Lettuce. - Tomatoes. - Onions. - Pickles. - Jalapeños. - Garlic. - Chipotle powder. - Mayonnaise. - Salt. - Pepper. - Oil. - Greaseproof paper. - Butter. ** The calling My quest to smash burgers at home didn't start until earlier this year, while watching the [[https://www.imdb.com/title/tt9764362/][The Menu]]. I just could't stop [[https://indieweb.social/@xenodium/109734285674122246][craving the burger]] from that scene, so I set out to start smashing my own. #+ATTR_HTML: :width 98% [[file:images/how-i-smash-burgers/the-menu.webp]] ** The gear Don't rush to buy anything fancy. Your existing gear will likely do the job just fine. I'd say try a few things out and only upgrade when needed. I'll share the gear I use and where I felt I needed tweaking. ** Skillet While I didn't have a griddle at home, I did have a couple of trusty [[https://www.lodgecastiron.com/][Lodge]] *skillets* ([[https://www.lodgecastiron.com/product/round-cast-iron-classic-skillet?sku=L8SK3][cast iron]] and [[https://www.lodgecastiron.com/product/carbon-steel-skillet?sku=CRS12][carbon steel]]). Both work great for burgers, though I have a slight preference for the carbon steel one, as it's the bigger of the two and gives a little more room for manoeuvring, specially when smashing two burgers at a time. #+ATTR_HTML: :width 250px [[file:images/how-i-smash-burgers/cast-iron.png]] #+ATTR_HTML: :width 250px [[file:images/how-i-smash-burgers/carbon.png]] Heat the skillet up and add a little oil. If the oil starts smoking, be quick to drop the patties and start smashing. ** Grill Spatula (too big/stiff for skillet) Somewhat inspired by the film, I got myself a wide spatula so I could firmly press those patties against the skillet, and to flip of course. While this kind of spatula may work well on a spacious griddle, I felt constrained on a relatively small cast iron. Specially when flipping. I went looking for an alternative. #+ATTR_HTML: :width 250px [[file:images/how-i-smash-burgers/spatula.png]] ** Spatula + smasher (my winning combo) Over at the [[https://reddit.com/r/castiron/][r/castiron]] subreddit, I discovered fish spatulas. They are fairly agile on cast irons but also work great for loosening burger patties before flipping. [[file:images/how-i-smash-burgers/ready.webp]] While effective for flipping, fish spatulas are obviously no good for smashing. So I got myself a burger smasher. This combo worked well for me. [[file:images/how-i-smash-burgers/smash.webp]] When smashing, use greaseproof paper to prevent the patties from sticking to the smasher. ** Ingredients While I've drawn inspiration from others, I've landed on my own preferred ingredients. I'm sure that will continue changing over time. Pick and choose as your heart desires. ** Minced/ground beef Minced beef with higher fat content (around 20-30%) is often recommended for a couple of reasons: - Flavour: Fat equals flavour in cooking. The higher fat content will melt during cooking and become 'self-basting', resulting in a juicier and more flavourful burger. - Texture: The fat in the beef melts under heat, helping the burger achieve a crispy, caramelized exterior known as the [[https://en.wikipedia.org/wiki/Maillard_reaction][Maillard reaction]], which contrasts nicely against the soft, juicy interior. In the UK, I can typically find minced beef with 15%-20% fat content at the main supermarkets. #+ATTR_HTML: :width 200px [[file:images/how-i-smash-burgers/pattie.png]] Be sure to salt and pepper to taste (as in picture) on one side. Once flipped on pan, salt and pepper the other side. ** Bacon I tend to prefer smoked streaky bacon, but hey these will be your burgers. Your burgers, your rules. #+ATTR_HTML: :width 250px [[file:images/how-i-smash-burgers/streaky.png]] ** Buns (brioche) I hear potato buns are great for burgers. I've yet to try them. So far, I've settled for brioche. I happen to find these near me, so I've gone with them. #+ATTR_HTML: :width 350px [[file:images/how-i-smash-burgers/brioche.png]] Butter the buns and brown on the skillet for a minute. Check the buns often. Brioche buns can burn quickly. ** American cheese American cheese is often the burger cheese of choice. #+ATTR_HTML: :width 98% [[file:images/how-i-smash-burgers/american-cheese.webp]] While American cheese isn't widely available in the UK, the individually wrapped orange-looking cheddar cheese slices work just fine. #+ATTR_HTML: :width 250px [[file:images/how-i-smash-burgers/cheese.png]] ** Toppings I like my burgers with lettuce, tomatoes, onions, pickles, and occasionally jalapeños. For pickles, I typically just take cornichons and slice them up. #+ATTR_HTML: :width 350px [[file:images/how-i-smash-burgers/toppings_x0.30.png]] ** Burger sauce (chipotle/garlic/mayo) While classic burger sauce is often made with mayo, ketchup, pickles, and mustard, I've gone fairly rogue here. You see, I love chipotle mayo. I'm also a fan of garlic mayo, so I figured why not both? Turns out these three ingredients work great together. I like to draw out the flavours by first mixing the garlic and chipotle with a little hot water. - 1 garlic clove. - 2 teaspoons of chipotle powder. - 1 tablespoon of hot water. - Pinch of salt. #+ATTR_HTML: :width 210px [[file:images/how-i-smash-burgers/sauce1.png]] #+ATTR_HTML: :width 210px [[file:images/how-i-smash-burgers/sauce2.png]] #+ATTR_HTML: :width 210px [[file:images/how-i-smash-burgers/sauce3.png]] ...and then thicken with mayo. - 1/4 cup of mayo. #+ATTR_HTML: :width 210px [[file:images/how-i-smash-burgers/sauce4.png]] #+ATTR_HTML: :width 210px [[file:images/how-i-smash-burgers/sauce5.png]] These are very rough measurements, tweak to your preference. Make more garlicky, spicier, or soften things by adding garlic, chipotle, or mayo. ** Assembling I like to assemble in the following order from the bottom bun up. 1. Sauce on bottom bun. 2. Lettuce. 3. Tomatoes. 4. Onions. 5. 2 patties (melted cheese on both). 6. Bacon. 7. Pickles. 8. Jalapeños. 9. Sauce on top bun (oops, I forgot in the picture). #+ATTR_HTML: :width 60% [[file:images/how-i-smash-burgers/open.png]] ...and here's the final product. #+ATTR_HTML: :width 60% [[file:images/how-i-smash-burgers/burger-cut.png]] If you gave smashing burgers a go, I'd love to hear about it.

I say mostly 'cause well, I'm fairly pragmatic about it. If there's a workflow elsewhere that's more appropriate for my needs, I'll happily use that instead. While I'd love to do my web browsing from my beloved editor, Firefox ticks the right boxes for me. I do most of my iOS coding in Emacs. It's a hybrid of sorts between Emacs and Xcode. If I need to use the debugger, Xcode is a clear winner for me. If I happen to be visiting a Swift file in an Emacs buffer, I typically used the handy =crux-open-with= from [[https://github.com/bbatsov/crux][crux]] to open in Xcode, and continue from there. This worked OK, but I always wished opening in Xcode would also jump to the same line number as the Emacs point (cursor) location. This is particularly useful if I had just spotted where I'd like to set a breakpoint in an Emacs buffer and need to transition over to Xcode. It turns out, there's a nifty command line utility for that. [[https://www.unix.com/man-page/osx/1/xed/][xed]], the Xcode text editor invocation tool. It enables telling Xcode what file to open and at what line number: #+begin_src sh xed -line 141 path/to/some/file.swift #+end_src With that in mind, I've added my own version of =crux-open-with=, using [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]]. When running on macOS, the function checks whether or not I'm visiting a buffer for a programming language, and opens the file in Xcode at the same line number. #+begin_src emacs-lisp :lexical no (defun dwim-shell-commands-open-externally () "Open file(s) externally."

If you find opening the same file in a different context handy, you may also like the package [[https://github.com/rmuslimov/browse-at-remote][browse-at-remote]] that opens the visited file at its corresponding remote location (for example, GitHub).

It does the job, but I won't remember it next time. May as well make another [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]] function out of it and conveniently invoke from Emacs via a memorable name plus fuzzy search. #+ATTR_HTML: :width 80% [[file:images/trimming-video-screenshots/trim.gif]] #+begin_src emacs-lisp :lexical no (defun dwim-shell-commands-image-trim-borders () "Trim image(s) border (useful for video screenshots)."

This is super handy to take a quick peek at any image. Sometimes, I'd like a little more than just viewing the image. I'd like to see basic image details like type, dimensions, and file size. The [[https://imagemagick.org/][imagemagick]] =identify= utility is pretty handy for that. #+begin_src bash identify -format "%m %wx%h %b" path/to/image.png #+end_src #+RESULTS: : PNG 2387x1055 2.28454MB I could easily invoke =shell-command= for this or even create a [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]] function (maybe I will), but if this info was proactively displayed in the mode line, I wouldn't have to fetch it myself. Since I know I can use the =identify= command for this, I may as well see if I can plug it into the mode line. Turns out this wasn't too bad by setting =setting mode-line-format=. I added a little logic to only include image details while in =image-mode= and rely on =process-lines= to fetch the details. This function returns a list, which is a happy coincidence since =mode-line-format= also expects a list. #+begin_src emacs-lisp :lexical no (setq-default mode-line-format '(" " mode-line-front-space mode-line-client mode-line-frame-identification mode-line-buffer-identification (:eval (when (eq major-mode 'image-mode) ;; Needs imagemagick installed.

To get around that, I could maybe create a temporary macOS user. Instead, I somewhat revisited the simulator route and looked for a VM option to run macOS. This gave me an excuse to play with VM options on macOS. I had been meaning to check out [[https://github.com/lima-vm/lima][lima]] as per Hacker News's [[https://news.ycombinator.com/item?id=36668964][Lima: A nice way to run Linux VMs on Mac]].

Learning to Edebug really /"is the right decision for anyone who doesn't know how to Edebug."/ Why, you may ask? He best puts it as /"running into errors is not only a consequence of tinkering with your editor, it is the only road to graduating in Emacs."/ For me personally, it /earned me that independence/ to bend Emacs my way. Don't like how something works? Pull up the debugger to help me understand how a package or function works. I've done this countless of times to bend things my way. Speaking of edebug, I had been meaning to tweak edebug's result display behaviour for quite some time. As you step through code, edbug prints the result of previous expressions to the minibuffer. This works well, but I couldn't help but feel like my eyes were constantly jumping between the code and the minibuffer at the bottom of the window. #+ATTR_HTML: :width 70% [[file:images/inline-previous-result-and-why-you-should-edebug/edebug-minibuffer.gif]] I wanted to minimize the eye jumping experience, so I figured I could likely bend things my way and print the result at point. How did I go about it? The same way I often do. Figure out what function is called for a given key binding via [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Key-Help.html][describe-key]] or my favourite replacement helpful-key from [[https://github.com/Wilfred/helpful][helpful.el]]. This led me to =edebug-next-mode= in =edebug.el=. At that point, I could have set a breakpoint in =edebug-next-mode= and eventually step into the relevant code, but hey we had a better clue. We knew that all output started with "Result:", so we could just search for that string in =edebug.el= instead. Jackpot! =edebug-compute-previous-result= and its adjacent =edebug-previous-result= are just the right functions: #+begin_src emacs-lisp :lexical no (defun edebug-compute-previous-result (previous-value) (if edebug-unwrap-results (setq previous-value (edebug-unwrap* previous-value))) (setq edebug-previous-result (concat "Result: " (edebug-safe-prin1-to-string previous-value) (eval-expression-print-format previous-value)))) (defun edebug-previous-result () "Print the previous result." (interactive) (message "%s" edebug-previous-result)) #+end_src We can see that =edebug-previous-result= invokes =message= which is responsible for displaying the debugged expression's result in the minibuffer. Modifying this functions behaviour would be enough to achieve inline display, but I also want to remove "Result:" from the displayed message. Neither of these functions offer configurability, so we'll resort to advising both functions.

I lost mine, so I took a picture of hers. I was fairly certain a barcode photo would scan just as well at self-checkout, and it did. This got me thinking about Apple's Wallet [[https://en.wikipedia.org/wiki/PKPASS][pkpasses]]. I don't really know much about them. Could I potentially create my own =.pkpass=? If I could just include the same barcode as in the photo, it should do the job just fine.

If you just want the official Wallet pass on your iPhone, use that. But I was curious about whether or not I could create my own pass. Turns out I /can/.

Using my limited [[https://www.gimp.org/][GIMP]] skills, I cropped one of the images and also replaced =strip.png=. The remaining customizations took place in =pass.json= and should be fairly self-explanatory. There's the text shown in all labels as well as three customizable colours (background, label, and foreground). #+begin_src json { "formatVersion": 1, "passTypeIdentifier": "my.com.identifier.passmaker", // also not my actual one.

Back then, I primarily relied on the [[https://developers.google.com/closure/compiler/][Google Closure Compiler]], now maybe an archaeological artefact? These days, it's hard not to bump into any JavaScript project that doesn't rely on [[https://www.npmjs.com/][npm]], along with many other tools like the [[https://www.typescriptlang.org/][Typescript]] compiler, [[https://eslint.org/][ESLint]], [[https://prettier.io/][Prettier]]... There are a ton of available frameworks too. I was somewhat put off (or maybe just lazy?) by the initial ramp-up to reenter the JavaScript world. I guess that's what some refer to as [[https://medium.com/@ericclemmons/javascript-fatigue-48d4011b6fc4#.prcj59904][Javascript Fatigue]]. I'm giving JavaScript another try, but this time with an Emacs [[https://github.com/xenodium/chatgpt-shell][chatgpt-shell]] standing by. Reentering the JavaScript world as a noob, I often know what I want to enable, but I'm unfamiliar with which project knobs to turn to set things up. While I may want to dig deeper into things in the future, at present I just want to dabble with JavaScript. I want a local project set up as quickly as possible. ChatGPT has been pretty handy at that. The Emacs ChatGPT shell and its minibuffer prompts work fairly well for my needs, yet I often found myself wishing it could behave more like a [[https://magit.vc/][magit]] commit buffer. That is, launch a dedicated buffer (not the shell itself), ask the question, maybe paste some snippets, and send it on its way with that oh so familiar and satisfying =C-c C-c= binding ([[https://www.gnu.org/software/emacs/manual/html_node/emacs/Sending-Mail.html][sending mail]] also says hello). This is where =M-x chatgpt-shell-prompt-compose= comes in. It's a mash between the ChatGPT shell and a magit commit buffer: #+ATTR_HTML: :width 85% [[file:images/a-cure-for-javascript-fatigue/node-chatgpt.gif]] In the background, the buffer is still powered by the shell itself, so you can reuse it to ask clarifying questions. #+ATTR_HTML: :width 85% [[file:images/a-cure-for-javascript-fatigue/compose.gif]] A couple of additional features worth mentioning... Invoking =chatgpt-shell-prompt-compose= with an active region automatically copies the region content over to the compose buffer. This is handy if you'd like to create more elaborate prompts with further editing. So far, this feels more natural than editing text from the shell or the minibuffer, where =RET= doesn't insert new lines. The compose buffer is powered by a background shell (storing history for us). Typing =clear= followed by =C-c C-c= clears the background shell history. =chatgpt-shell-prompt-compose= is available in [[https://github.com/xenodium/chatgpt-shell][chatgpt-shell]] v0.72.1. I've so far bound it to =C-c C-e=, though I've already found some unfortunate clashes. * [2023-07-12 Wed] ChatGPT visits the Emacs doctor :PROPERTIES: :CUSTOM_ID: chatgpt-visits-the-emacs-doctor :END: Emacs is a [[https://youtu.be/urcL86UpqZc?t=177][part-time job]].

I figured a shell interface would be a great fit for the interaction.

If you want to run it, you'll need chatgpt-shell [[https://github.com/xenodium/chatgpt-shell#install][installed and set up]]. 2. This was a quick fun hack. No code judging ;) The snippet is further down... Start with =chatgpt-shell-visit-doctor= as the entry point, setting things up for us. It creates both the =*chatgpt*= and =*doctor*= buffers and arranges the windows next to each other. We also set a ChatGPT system prompt to guide things a little: #+begin_quote "Pretend to be an overwhelmed Emacs user who is obsessed with configuring their init.el file. You are in a session talking to a psychotherapist. Limit your output to no more than 20 words. In the course of 5 exchanges between you and the therapist, show improvements.

We don't want the session to abruptly end without a resolution, so we'll use /Thank you doc, I think I'm cured!/ as our key phrase to end the session. We register =chatgpt-shell--on-chatgpt-patient-response= as a hook to receive ChatGPT output, which we feed to the =*doctor*= buffer. We subsequently get a doctor response that's fed back to ChatGPT via =chatgpt-shell--insert-doc-response=. We add some additional freebies like binding =Ctrl-c Ctrl-c= to =chatgpt-shell-leave-doctor=, so we can bail out of the exchange from the =*chatgpt*= buffer. We also introduced =chatgpt-shell--insert-delayed-text= as a replacement for [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Insertion.html][insert]] to slow things down a little.

Does it bother you that you are overwhelmed by your obsession with customizing your emacs configuration? Absolutely! I feel trapped in an endless cycle of tweaking and configuring, unable to achieve satisfaction. Why do you say that? I constantly seek perfection in my Emacs config, but it's an unattainable goal that leaves me exhausted and frustrated. When did you first know that it's an unattainable goal that leaves you exhausted and frustrated? I've realized it recently after spending countless hours trying to perfect my Emacs configuration without any lasting satisfaction. Are you sure? Thanks you doc, I think I'm cured. #+end_quote While we can work exclusively with the =*doctor*= buffer making requests directly to the ChatGPT API, where's the fun in that? Getting the buffers to talk to each other enables us to marvel at both the beauty and absurdity of being able to glue anything together in our lovely Emacs world.

It's been a little while, so here's an update with the latest additions. Like this project? Consider ✨[[https://github.com/sponsors/xenodium][sponsoring]]✨. ** Multi-session support You can run multiple shell instances independently configured to use different versions or system prompts. This was biggest recent change. Please report issues. #+ATTR_HTML: :width 95% [[file:images/chatgpt-shell-v0601-updates/cat-turtle.gif]] ** Display system prompt and version The current shell's version and system prompt are now displayed more prominently in both the shell prompt and buffer name. #+ATTR_HTML: :width 90% [[file:images/chatgpt-shell-v0601-updates/display.png]] With multi-session support, displaying shell details in the buffer name becomes more important as it makes it easier to find shells across your buffer list. ** Rename shell buffers While buffer names are now automatically derived, one can also use =chatgpt-shell-rename-buffer= to use custom buffer names. ** ob-chatgpt-shell improvements Use =:temperature= to specify the [[https://platform.openai.com/docs/api-reference/completions/create#completions/create-temperature][temperature]]. Use =:context CONTEXT-NAME= to pick and choose which source blocks to aggregate as context. Thank you [[https://github.com/jtmoulia][Thomas Moulia]]. Use =:preflight t= to debug =ob-chatgpt-shell= execution. #+ATTR_HTML: :width 60% [[file:images/chatgpt-shell-v0601-updates/preflight.png]] ** chatgpt-shell-write-git-commit Adds =chatgpt-shell-write-git-commit=, so you can generate commit messages using the current region. Thank you [[https://github.com/bigsky77][Simon Judd]]. ** Approximate context length =chatgpt-shell= now uses =chatgpt-shell--approximate-context-length= to approximate the context size and discard history if necessary. This is pretty experimental but seems to work well enough. It's enabled by default to get some feedback. Please file bugs if needed or send PRs to improve. ** =S-= for multiline input In addition to =C-J= to insert multi-line input, =S-= is also supported. Thank you [[https://github.com/shouya][shouya]] for the submission. ** Welcome message A welcome message now makes the help much more discoverable for new or sporadic users. Thank you [[https://github.com/shouya][shouya]] for the suggestion. #+ATTR_HTML: :width 75% [[file:images/chatgpt-shell-v0601-updates/welcome.png]] ** Help me While the [[https://github.com/xenodium/chatgpt-shell][README]] documents the shells and Emacs is [[https://www.emacswiki.org/emacs/SelfDocumentation][self-documenting]], we now have a =help= command to make things a little more discoverable. #+ATTR_HTML: :width 99% [[file:images/chatgpt-shell-v0601-updates/help.png]] ** Hello chatgpt-shell-mode and dall-e-shell-mode Both =chatgpt-shell= and =dall-e-shell= are both based on =shell-maker= and until recently both shared =shell-maker-mode= as their major mode. This didn't play well with yasnippet. Both shells now enable independent major modes: =chatgpt-shell-mode= and =dall-e-shell-mode=. Thank you [[https://github.com/djliden][Daniel Liden]] for the proposal. ** Saving transcript customizations Make transcript saving more customizable via =shell-maker-transcript-default-path= and =shell-maker-transcript-default-filename=. Thank you [[https://github.com/gnusupport][gnusupport]]. ** New ChatGPT model versions New OpenAI model versions were recently released and added to chatgpt-shell: =gpt-3.5-turbo-0613= and =gpt-4-0613=. Thanks you [[https://github.com/suzuki][Norio Suzuki]]. ** Load awesome prompts =M-x chatgpt-shell-load-awesome-prompts= to download and import curated prompts from [[https://github.com/f/awesome-chatgpt-prompts][awesome-chatgpt-prompts]].

Thank you [[https://github.com/wmedrano][William Medrano]] for the solution. ** Configurable prompts Functions like =chatgpt-shell-describe-code= ask ChatGPT to describe the code in region. These functions used hardcoded English prompts. These are now configurable, so users can tweak or translate if preferred.

He offers a solution using a custom interactive command. His use-case resonated with me. Similarly, James' recommendation to bind his file-duplicating command to =C-c d= [1] sent a signal to my brain triggering [[https://twitter.com/bbatsov][Bozhidar Batsov]]'s =crux-duplicate-current-line-or-region=. =crux-duplicate-current-line-or-region= is part of a "collection of Ridiculously useful extensions for Emacs" (yeah that's [[https://github.com/bbatsov/crux][crux]]).

Partly because it's fairly quick and partly 'cause it's fun. Jame's post gave me yet another opportunity to exercise my errrm part-time job. This time, duplicating files. All I need is the [[https://www.man7.org/linux/man-pages/man1/cp.1.html][cp]] utility and a template: #+begin_src sh cp -R '<>' '<>' #+end_src I seldom type these template's myself when I want to execute a command (via =M-x dwim-shell-command=). I typically wrap these templates in interactive commands, making them easily accessible via =M-x= and your favorite completion framework. I happen to use [[https://github.com/abo-abo/swiper][ivy]]. #+begin_src emacs-lisp :lexical no (require 'dwim-shell-command) (defun dwim-shell-commands-duplicate () "Duplicate file(s)." (interactive) (dwim-shell-command-on-marked-files "Duplicate file(s)." "cp -R '<>' '<>'" :utils "cp")) #+end_src There's nothing much to the command. Most logic is handled by the template, replacing =<>= with the current file and =<>= with a uniquified version of it. Having said this, there's a bunch of free [[https://xenodium.com/emacs-dwim-do-what-i-mean/][DWIM]] love that kicks in, courtesy of the =dwim-shell-command= package by yours truly. Let's give our new =dwim-shell-commands-duplicate= command a spin. Like =crux-duplicate-current-line-or-region= duplicates the current line, our new command duplicates the current dired file. #+ATTR_HTML: :width 95% [[file:images/duplicate-this/duplicate-file.gif]] Got multiple files to duplicate? Like =crux-duplicate-current-line-or-region=, we can use the region for a similar purpose. #+ATTR_HTML: :width 95% [[file:images/duplicate-this/duplicate-files.gif]] While we have been using the region to duplicate adjacent files, we can also mark specific files. #+ATTR_HTML: :width 95% [[file:images/duplicate-this/duplicate-marked.gif]] Our =cp -R '<>' '<>'= template uses the =-R= (recursive) flag, so we get another freebie. In addition to files, we can also duplicate directories. #+ATTR_HTML: :width 95% [[file:images/duplicate-this/duplicate-dirs.gif]] Lastly, because we're on a DWIM train, if your current buffer happens to be visiting a file, you can =M-x dwim-shell-commands-duplicate= the current file to duplicate it. You're automatically dropped to a dired buffer, with point on the new file (à la [[https://emacsredux.com/blog/2013/09/24/dired-jump/][dired-jump]]). #+ATTR_HTML: :width 95% [[file:images/duplicate-this/duplicate-buffer.gif]] While duplicating files using a template was a mere =cp -R '<>' '<>'= away, we get a bunch of free DWIM magic applied to a handful of use-cases and contexts. What made the file-duplicating use-case extra special is that it maps almost exactly to an equivalent text command. Keep the same key bindings and we almost get a "[[https://endlessparentheses.com/hungry-delete-mode.html][free feature]]". #+begin_src emacs-lisp :lexical no (use-package crux :ensure t :commands crux-open-with :bind (("C-c d" . crux-duplicate-current-line-or-region))) (use-package dwim-shell-command :ensure t :bind (:map dired-mode-map ("C-c d" . dwim-shell-commands-duplicate)) :config ;; Loads all my own dwim shell commands ;; (including `dwim-shell-commands-duplicate') (require 'dwim-shell-commands)) #+end_src You can find my ever-growing list of similar commands over at [[https://github.com/xenodium/dwim-shell-command/blob/main/dwim-shell-commands.el][dwim-shell-commands.el]] (the optional part of the package).

[1]: I actually use =C-x C-d= for =crux-duplicate-current-line-or-region= but same same... ** Update If you're keen on a regex-based approach, [[https://www.reddit.com/user/arthurno1/][u/arthurno1]] [[https://www.reddit.com/r/emacs/comments/14rmvkx/comment/jqtkel8/?utm_source=share&utm_medium=web2x&context=3][offers a great built-in alternative]]: dired-do-copy-regexp (bound to =% C=). * [2023-06-29 Thu] Stitching images from the comfort of dired :PROPERTIES: :CUSTOM_ID: joining-images-from-the-comfort-of-dired :END: I recently wanted a few images stitched together. A perfect job for [[https://imagemagick.org/][ImageMagick]]. A quick search yielded the magical incantation: #+begin_src sh convert image1.jpg image2.jpg image3.jpg +append joined.jpg #+end_src Great, now I know, but I'll rarely use it and will soon forget it. I may as well add it to my [[https://github.com/xenodium/dwim-shell-command/blob/main/dwim-shell-commands.el][repository]] of [[https://en.wikipedia.org/wiki/DWIM][DWIM]] command line utilities, wrapped in a convenient Emacs function, applicable from different contexts... [[https://xenodium.com/emacs-dwim-do-what-i-mean/][know what I mean]]? 🙃 I built [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]] for this purpose. You can take the above command and easily turn it into an interactive Emacs command with something like the following: #+begin_src emacs-lisp :lexical no (require 'dwim-shell-command) (defun dwim-shell-commands-join-images-horizontally () "Join all marked images horizontally as a single image." (interactive) (dwim-shell-command-on-marked-files "Join images horizontally" "convert -verbose '<<*>>' +append 'joined.jpg'" :utils "convert")) #+end_src You can select as many images as you'd like from the comfort of your dired and /make the ImageMagick happen/. #+ATTR_HTML: :width 95% [[file:images/joining-images-from-the-comfort-of-dired/burgers.gif]] The snippet does the job just fine, but we can make it smarter. For starters, let's not hardcode the output filename. We'll ask the user instead. While we're asking, let's offer a default filename, but let's not assume the output extension is =.jpg=. Let's guess based on the image selection. While we're at it, let's not override the output file if already exists. Uniquify it. Most of the above can be achieved by either using [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]] helpers or its templating language. For example, =<>= ensures that if =joined.png= already exists, it automatically generates =joined(1).png= instead. #+begin_src emacs-lisp :lexical no (require 'dwim-shell-command) (defun dwim-shell-commands-join-images-horizontally () "Join all marked images horizontally as a single image." (interactive) (let ((filename (format "joined.%s" (or (seq-first (dwim-shell-command--file-extensions)) "png")))) (dwim-shell-command-on-marked-files "Join images horizontally" (format "convert -verbose '<<*>>' +append '<<%s(u)>>'" (dwim-shell-command-read-file-name (format "Join as image named (default \"%s\"): " filename) :default filename)) :utils "convert"))) #+end_src Here's the new horizontal command in action... #+ATTR_HTML: :width 95% [[file:images/joining-images-from-the-comfort-of-dired/burger_row_x1.5_optimized.gif]] Notice how this time we didn't mark the images using =dired-mark=, typically bound to =m=. Instead, we made our selection using the region. Also, if you haven't gotten your junk food fix yet, here's the fries equivalent ;) #+ATTR_HTML: :width 95% [[file:images/joining-images-from-the-comfort-of-dired/fries_row_x1.5_optimized.gif]] We'll rinse all and repeat to get the vertical command equivalent.

The idea is simple. Add a placeholder like =<>= to an [[https://orgmode.org/manual/Working-with-Source-Code.html][org babel]] source block, and it will be automatically replaced (verbatim) with the content (or result) of referred block before execution. You'll also need the =:noweb yes= header argument. #+begin_src org ,#+NAME: other-block ,#+begin_src swift print("Hello 0") ,#+end_src ,#+RESULTS: other-block : Hello 0 ,#+BEGIN_SRC swift :noweb yes <> print("Hello 1") ,#+END_SRC ,#+RESULTS: : Hello 0 : Hello 1 #+end_src Since =<>= is replaced with the content of said block, at execution time, the block is effectively equivalent to executing: #+BEGIN_SRC swift print("Hello 0") print("Hello 1") #+END_SRC #+RESULTS: : Hello 0 : Hello 1 Why is this so versatile? Org babel can include/execute all sorts of languages, so you can mix and match the result from one language and massage it to appear as the body of another block using the same (or different) language. I was recently asked [[https://github.com/xenodium/chatgpt-shell/issues/102][how to include the result from one babel block in another]] using [[https://github.com/xenodium/chatgpt-shell/#chatgpt-org-babel][ob-chatgpt-shell]]. While the initial question was looking for a solution involving variables, we can use noweb to achieve a similar goal. Note that in this case, I'll be using =<>=, with =()=, to refer to =#+RESULTS:= rather than the source block itself. #+begin_src org ,#+NAME: hello ,#+BEGIN_SRC chatgpt-shell Say hello in spanish ,#+END_SRC ,#+RESULTS: hello Hola ,#+BEGIN_SRC chatgpt-shell :noweb yes <> What does the previous line say verbatim? ,#+END_SRC #+end_src Executing the block #+BEGIN_SRC chatgpt-shell :noweb yes <> What does the previous line say verbatim? #+END_SRC Gives us #+RESULTS: : The previous line says "Hola". On a similar note, I was asked if the results from a previous source block could be [[https://indieweb.social/@kickingvegas@sfba.social/110562099134297469][fed to a Swift Chart block]] using [[https://github.com/xenodium/ob-swiftui][ob-swiftui]]. While I'm new to [[https://developer.apple.com/documentation/Charts][Swift Charts]], I do love glueing things via Emacs lisp. I figured I could write a little elisp to generate random data and feed it to a SwiftUI block via =<>=. The result is pretty neat, based on Apple's [[https://developer.apple.com/documentation/charts/linemark][LineMark example]]. #+ATTR_HTML: :width 95% [[file:images/noweb-more-glue-for-your-org-toolbox/data-chart.gif]] #+begin_src org ,#+NAME: data ,#+begin_src emacs-lisp :lexical no (concat (mapconcat (lambda (n) (format "MonthlyHoursOfSunshine(city: \"Seattle\", month: %d, hoursOfSunshine: %d)," n (random 100))) (number-sequence 1 20) "\n") "\n" (mapconcat (lambda (n) (format "MonthlyHoursOfSunshine(city: \"Cupertino\", month: %d, hoursOfSunshine: %d)," n (random 100))) (number-sequence 1 20) "\n")) ,#+end_src ,#+begin_src swiftui :results file :noweb yes import Charts struct MonthlyHoursOfSunshine: Identifiable { var city: String var date: Date var hoursOfSunshine: Double var id = UUID() init(city: String, month: Int, hoursOfSunshine: Double) { let calendar = Calendar.autoupdatingCurrent self.city = city self.date = calendar.date(from: DateComponents(year: 2020, month: month))! self.hoursOfSunshine = hoursOfSunshine } } struct ContentView: View { var data: [MonthlyHoursOfSunshine] = [ <> ] var body: some View { Chart(data) { LineMark( x: .value("Month", $0.date), y: .value("Hours of Sunshine", $0.hoursOfSunshine) ) .foregroundStyle(by: .value("City", $0.city)) } .frame(minWidth: 800, minHeight: 300) .padding() .colorScheme(.dark) } } ,#+end_src #+end_src While I've shown fairly basic usages of noweb, we can accomplish some nifty integrations.

Take a major mode like =emacs-lisp-mode= as an example. To customize its behaviour, one may add a hook function to =emacs-lisp-mode-hook=, or if you're a little lazy while experimenting, you may even use a lambda. #+begin_src emacs-lisp :lexical no (add-hook 'emacs-lisp-mode-hook #'my/emacs-lisp-mode-config) (add-hook 'emacs-lisp-mode-hook (lambda () (message "I woz ere"))) #+end_src =emacs-lisp-mode-hook='s content would subsequently look as follows: #+begin_src emacs-lisp :lexical no '(my/emacs-lisp-mode-config (lambda nil (message "I woz ere")) ert--activate-font-lock-keywords easy-escape-minor-mode lisp-extra-font-lock-global-mode) #+end_src Maybe =my/emacs-lisp-mode-config= didn't work out for us and we'd like to remove it. We can use =remove-hook= for that and evaluate something like: #+begin_src emacs-lisp :lexical no (remove-hook 'emacs-lisp-mode-hook #'my/emacs-lisp-mode-config) #+end_src The lambda can be removed too, but you ought to be careful in using the same lambda body. #+begin_src emacs-lisp :lexical no (remove-hook 'emacs-lisp-mode-hook (lambda () (message "I woz tere"))) #+end_src There are other ways to remove the lambdas, but we're digressing here... We typically have to write these throwaway snippets to undo our experiments. What if we just had a handy helper always available to remove items from sequences /(edit: we do, =remove-hook= is already interactive, see Update 2 below)/? After all, hooks are just lists (sequences). #+ATTR_HTML: :width 70% [[file:images/deleting-from-emacs-sequence-vars/removed-lambda.gif]] While the interactive command can likely be simplified further, I tried to optimize for ergonomic usage. For example, =completing-read= gives us a way narrow down whichever variable we'd like to modify as well as the item we'd like to remove. =seqp= is also handy, as we filter out noise by automatically removing any variable that's not a sequence. #+begin_src emacs-lisp :lexical no (defun ar/remove-from-list-variable () (interactive) (let* ((var (intern (completing-read "From variable: " (let (symbols) (mapatoms (lambda (sym) (when (and (boundp sym) (seqp (symbol-value sym))) (push sym symbols)))) symbols) nil t))) (values (mapcar (lambda (item) (setq item (prin1-to-string item)) (concat (truncate-string-to-width (nth 0 (split-string item "\n")) (window-body-width)) (propertize item 'invisible t))) (symbol-value var))) (index (progn (when (seq-empty-p values) (error "Already empty")) (seq-position values (completing-read "Delete: " values nil t))))) (unless index (error "Eeek.

Sure, we have debuggers and [[https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop][REPLs]] which are super useful, but sometimes you just know that sprinkling your code with a handful of temporary prints/logs will get you enough info to fix an issue. I must confess, my temporary print statements are fairly uninspiring. Sometimes I log the name of the method/function, but I also resort to less creative options like =print("Yay")= or =print("Got here")=. My laziness and lack of creativity knows no boundaries, so if I need multiple unique entries, I often copy, paste, and append numbers to my entries: =print("Yay 2")=, =print("Yay 3")=, =print("Yay 4")=... I know, are you judging yet? So rather than develop the creative muscle, I've decided to lean on laziness and old habits, so let's make old habit more efficient :) I no longer want to copy, paste, and increment my uncreative log statements. Instead, I'll let Emacs do it for me! #+ATTR_HTML: :width 70% [[file:images/sprinkle-me-logs/log-elisp.gif]] There isn't a whole lot to the implementation. It searches the current buffer for other instances of the same logging string and captures the largest counter found. It subsequently prints the same string with the counter incremented.

Don't worry, this isn't really another ChatGPT post.

Not ideal, as it'll require a little more careful maintenance in the future. Emacs being the self-documenting editor that it is, I figured I should be able to extract customizable variables, commands, along with their respective docs, and generate these very same org tables. I had no idea how to go about this, but [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Apropos.html][apropos-variable]] and [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Apropos.html][apropos-command]] surely knew where to fetch the details from. A peek into =apropos.el= quickly got me on my way. Turns out [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Creating-Symbols.html#Definition-of-mapatoms][mapatoms]] is just what I needed. It iterates over [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Creating-Symbols.html][obarray]], Emacs's symbol table. We can use it to extract the symbols we're after. Since we're filtering symbols from =chatgpt-shell=, we can start by including only those whose =symbol-name= match "^chatgpt-shell". Out of all matching, we should only keep custom variables. We can use =custom-variable-p= to check for that. This gives us all relevant variables. We can subsequently get each variable's corresponding docs using =(get symbol 'variable-documentation)= and put it into a list. Now, if we pull our org babel rabbit out of our Emacs magic hat, we can use =:results table= to print the list as an org table. The source block powering this magic trick looks as follows: #+begin_src org ,#+begin_src emacs-lisp :results table :colnames '("Custom variable" "Description") (let ((rows)) (mapatoms (lambda (symbol) (when (and (string-match "^chatgpt-shell" (symbol-name symbol)) (custom-variable-p symbol)) (push `(,symbol ,(car (split-string (or (get (indirect-variable symbol) 'variable-documentation) (get symbol 'variable-documentation) "") "\n"))) rows)))) rows) ,#+end_src #+end_src And just like that... we effortlessly get our elisp docs in an org table, straight from Emacs's symbol table. #+ATTR_HTML: :width 100% [[file:images/generating-elisp-org-docs/docs.gif]] It's worth noting that our snippet used =indirect-variable= to resolve aliases but also limited descriptions to the first line in each docstring. To build a similar table for interactive commands, we can use the following block (also including bindings). #+begin_src org ,#+BEGIN_SRC emacs-lisp :results table :colnames '("Binding" "Command" "Description") (let ((rows)) (mapatoms (lambda (symbol) (when (and (string-match "^chatgpt-shell" (symbol-name symbol)) (commandp symbol)) (push `(,(mapconcat #'help--key-description-fontified (where-is-internal symbol shell-maker-mode-map nil nil (command-remapping symbol)) ", ") ,symbol ,(car (split-string (or (documentation symbol t) "") "\n"))) rows)))) rows) ,#+END_SRC #+end_src #+ATTR_HTML: :width 100% [[file:images/generating-elisp-org-docs/commands.gif]] You see?

Since then, it's turned into a package of sorts, evolving with [[https://github.com/xenodium/chatgpt-shell/issues?q=is%3Aissue+is%3Aclosed+][user feedback]] and [[https://github.com/xenodium/chatgpt-shell/pulls?q=is%3Apr+is%3Aclosed][pull requests]]. ** Now on MELPA While [[https://github.com/xenodium/chatgpt-shell][chatgpt-shell]] is a young package still, it seems useful enough to share more widely. As of today, =chatgpt-shell= is [[https://melpa.org/#/chatgpt-shell][available on MELPA]].

I happen to use Oleh Krehel's [[https://github.com/abo-abo/swiper][ivy]]. ** shell-maker (make your own AI shells) While ChatGPT is a popular service, there are many others sprouting. Some are cloud-based, others local, proprietary, open source... In any case, it'd be great be able to hook on to them without much overhead.

If you've read a handful of my posts, you would have come across either a screenshot or a short clip with some demo. Historically, I've used the macOS's built-in utility invoked via =⌘ + Shift + 5=. It does a fine job for screenshots. For video captures, it's got a couple of small quirks. ** Record window Unlike screenshots, macOS video capture cannot record a specific window. While you can select a region, it's easy to inadvertently include a portion of your wallpaper in the recording. Not a big deal, but I felt posted screencasts could look as clean as their screenshot counterparts if we could record the window alone. Let's compare grabbing a region vs window alone. I know the clean look may be subjective, but see what I mean? #+CAPTION: Capture region (includes wallpaper/background) #+ATTR_HTML: :width 50% [[file:images/recordscreenshot-windows-the-lazy-way/record-bg.gif]] #+CAPTION: Capture window only (ahhh, so clean) #+ATTR_HTML: :width 50% [[file:images/recordscreenshot-windows-the-lazy-way/record.gif]] ** Cancel recording macOS has a handy shortcut (=⌘ + Ctrl + Esc=) to stop recording. If you got your demo right, you're done. If not, you have one more step remaining (right click to delete the blooper). #+ATTR_HTML: :width 40% [[file:images/recordscreenshot-windows-the-lazy-way/delete.png]] Also not a huge deal, but I was hoping for a single shortcut to stop recording _and_ also automatically discard. I haven't found one, but would love to hear if otherwise. ** macosrec enters the chat I wanted more flexibility to build my own recording/screenshotting flows. A command line utility could be quite versatile at that, so I built [[https://github.com/xenodium/macosrec][macosrec]]. =macosrec= enables taking a screenshot or recording a window video entirely from the command line. #+ATTR_HTML: :width 60% [[file:images/recordscreenshot-windows-the-lazy-way/macosrec.gif]] ** elisp glues the world Command line utilities can be invoked in all sorts of ways, but I'm an Emacs nutter so you can see where this is going... I want Emacs key bindings to control the lot. | C-c _ | Take screenshot of a window | | C-c ( | Start recording window | | C-c ) | Stop recording window | | C-c 8 | Abort recording | Integrating command line utilities into Emacs and making them quickly accessible seems to have become a full-time hobby of mine. I kid, but it's become a pretty painless process for me. I built [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]] for that. If you've never heard of [[https://en.wikipedia.org/wiki/DWIM][DWIM]], it stands for "Do what I mean". To give you an idea of the kinds of things I'm using DWIM commands for, check the following out: - dwim-shell-commands-audio-to-mp3 - dwim-shell-commands-bin-plist-to-xml - dwim-shell-commands-clipboard-to-qr - dwim-shell-commands-drop-video-audio - dwim-shell-commands-files-combined-size - dwim-shell-commands-git-clone-clipboard-url - dwim-shell-commands-git-clone-clipboard-url-to-downloads - dwim-shell-commands-image-to-grayscale - dwim-shell-commands-image-to-icns - dwim-shell-commands-image-to-jpg - dwim-shell-commands-image-to-png - dwim-shell-commands-pdf-password-protect - dwim-shell-commands-reorient-image - dwim-shell-commands-resize-gif - dwim-shell-commands-resize-image - dwim-shell-commands-resize-video - dwim-shell-commands-speed-up-gif - dwim-shell-commands-speed-up-video - dwim-shell-commands-unzip - dwim-shell-commands-video-to-gif - dwim-shell-commands-video-to-optimized-gif - dwim-shell-commands-video-to-webp If it ever took you a little while to find the right command incantation to get things right, only to forget all about it next time you need it ([[https://xenodium.com/emacs-ffmpeg-and-macos-alias-commands][I'm looking at you ffmpeg]]), =dwim-shell-command= can help you easily save things for posterity and make them easily accessible in the future. Since we're talking ffmpeg, here's all it takes to have gif conversion handy: #+begin_src emacs-lisp :lexical no (defun dwim-shell-commands-video-to-gif () "Convert all marked videos to gif(s)." (interactive) (dwim-shell-command-on-marked-files "Convert to gif" "ffmpeg -loglevel quiet -stats -y -i '<>' -pix_fmt rgb24 -r 15 '<>.gif'" :utils "ffmpeg")) #+end_src There's no way I'll remember the ffmpeg command, but I can always fuzzy search my trusty commands with something like ="to gif"= and apply to either the current buffer file or any selected [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Dired.html][dired]] files. #+ATTR_HTML: :width 60% [[file:images/recordscreenshot-windows-the-lazy-way/to-gif.png]] So where am I going with this? I wrote DWIM shell commands for the bindings I previously described: | C-c _ | =dwim-shell-commands-macos-screenshot-window= | | C-c ( | =dwim-shell-commands-macos-start-recording-window= | | C-c ) | =dwim-shell-commands-macos-end-recording-window= | | C-c 8 | =dwim-shell-commands-macos-abort-recording-window= | Out of all of commands, =dwim-shell-commands-macos-start-recording-window= is likely the most interesting one. #+begin_src emacs-lisp :lexical no (defun dwim-shell-commands-macos-start-recording-window () "Select and start recording a macOS window." (interactive) (let* ((window (dwim-shell-commands--macos-select-window)) (path (dwim-shell-commands--generate-path "~/Desktop" (car window) ".mov")) (buffer-file-name path) ;; override so <> picks it up (inhibit-message t)) (dwim-shell-command-on-marked-files "Start recording a macOS window."

The nifty part is that when it's done recording (and saving the .mov file), it automatically creates multiple variants. For starters, it creates x1.5 and x2 .mov videos, but it also generates their .gif counterparts. #+ATTR_HTML: :width 60% [[file:images/recordscreenshot-windows-the-lazy-way/bunch.png]] Let's recap here for a sec. You start recording a window video with =C-c (=, end with =C-c )=, and automagically have all these generated files waiting for you. You can subsequently inspect any of the video candidates and pick the most appropriate variant. Discard whatever else you don't need. The output bundle is tailored to my needs. Maybe you want to invoke [[https://www.lcdf.org/gifsicle/][gifsycle]] for more optimized versions? Or maybe you want automatic webp generation via =ffmpeg=? DWIM does that I mean, so you likely have other plans... =dwim-shell-commands-macos-start-recording-window= and all other DWIM commands are now included in [[https://github.com/xenodium/dwim-shell-command/blob/main/dwim-shell-commands.el][dwim-shell-commands.el]], which ships optionally as part of [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]]. [[https://github.com/xenodium/macosrec][macosrec]] is also on GitHub, but if you want to be on your way, you can install via: #+begin_src sh brew tap xenodium/macosrec brew install macosrec #+end_src This is my way to record and screenshot windows the lazy way. How would you tweak to make it yours? * [2023-04-20 Thu] ob-swiftui updates :PROPERTIES: :CUSTOM_ID: ob-swiftui-updates :END: While [[https://indieweb.social/@xenodium/110227186721704189][experimenting with delegating Markdown]] blocks to [[https://orgmode.org/worg/org-contrib/babel/][Org babel]] in Emacs [[https://github.com/xenodium/chatgpt-shell][chatgpt-shell]], I resurrected [[https://github.com/xenodium/ob-swiftui][ob-swiftui]]. A package I had written to execute and render SwiftUI blocks in org babel. [[https://github.com/xenodium/ob-swiftui][ob-swiftui]] has two modes of rendering SwiftUI blocks: =:results window=, which runs outside of Emacs in a native window and =:results file=, which renders and saves to a file. The latter can be viewed directly from Emacs. =:results file= was a little clunky. That is, it hardcoded dimensions I had to manually modify if the canvas wasn't big enough. It was also a little slow. The clunkyness really came through with my chatgpt-shell experiments, so I took a closer look and made a few changes to remove hardcoding and speeds things up. The results ain't too shabby. #+ATTR_HTML: :width 80% [[file:images/ob-swiftui-updates/file-render.gif]] Another tiny improvement is that if you'd like to compose a more complex layout made of multiple custom views, =ob-swiftui= now looks for a =ContentView= as that root view by default. Specifying another root view was already possible but it had to be explicitly requested via =:view= param. You can now omit the =:view= param if you name the root view =ContentView=: #+begin_src org ,#+begin_src swiftui struct ContentView: View { var body: some View { TopView() BottomView() } } struct TopView: View { var body: some View { Text("Top text") } } struct BottomView: View { var body: some View { Text("Bottom text") } } ,#+end_src #+end_src The improvements have been pushed to [[https://github.com/xenodium/ob-swiftui][ob-swiftui]] and will soon be picked up on [[https://melpa.org/#/ob-swiftui][melpa]].

However, I found it complements my shell ([[https://www.masteringemacs.org/article/complete-guide-mastering-eshell][eshell]]) quite well. While I was sceptical at first, once I hid the mode line in my shell I never looked back. I just didn't miss it. I also love the uncluttered clean vibe.

I was fairly new to both [[https://openai.com/blog/chatgpt][ChatGPT]] and building anything on top of [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Shell-Prompts.html][comint]]. It was a fun exercise, which also generated some interest. As mentioned in the previous post, I took inspiration in other Emacs packages (primarily [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Lisp-Interaction.html][ielm]]) to figure out what I needed from comint. Soon, I got ChatGPT working. #+ATTR_HTML: :width 80% [[file:images/a-shell-maker/streamer.gif]] As I was looking at [[https://openai.com][OpenAI]] API docs, I learned about DALL-E: "an AI system that can create realistic images and art from a description in natural language." Like ChatGPT, they also offered an API to DALL-E, so I figured I may as well try to write a shell for that too... and I did. #+ATTR_HTML: :width 60% [[file:images/a-shell-maker/dalle.gif]] There was quite a bit of code duplication between the two Emacs shells I had just written. At the same time, I started hearing from folks about integrating other tools, some cloud-based, some local, proprietary, open source.. There's [[https://about.sourcegraph.com/cody][Cody]], [[https://github.com/invoke-ai/InvokeAI][invoke-ai]], [[https://github.com/ggerganov/llama.cpp][llama.cpp]], [[https://github.com/antimatter15/alpaca.cpp][alpaca.cpp]], and the list continues to grow. With that in mind, I set out to reduce the code duplication and consolidate into a reusable package.

I had been meaning to give [[https://openai.com/blog/chatgpt][ChatGPT]] a good try, preferably from Emacs. As an [[https://www.gnu.org/software/emacs/manual/html_mono/eshell.html][eshell]] fan, ChatGPT seemed like the perfect fit for a shell interface of sorts. With that in mind, I set out to wire ChatGPT with Emacs's general command interpreter ([[https://www.gnu.org/software/emacs/manual/html_node/emacs/Shell-Prompts.html][comint]]). I had no previous experience building anything comint-related, so I figured I could just take a peek at an existing comint-derived mode to achieve a similar purpose. =inferior-emacs-lisp-mode= ([[https://www.gnu.org/software/emacs/manual/html_node/emacs/Lisp-Interaction.html][ielm]]) seemed to fit the bill just fine, so I borrowed quite a bit to assemble a basic shell experience. From then on, it was mostly about sending each request over to the ChatGPT API to get a response. For now, I'm relying on [[https://curl.se/docs/manpage.html][curl]] to make each request. The invocation is fairly straightforward: #+begin_src sh curl "https://api.openai.com/v1/chat/completions" \ -H "Authorization: Bearer YOUR_OPENAI_KEY" \ -H "Content-Type: application/json" \ -d "{ \"model\": \"gpt-3.5-turbo\", \"messages\": [{\"role\": \"user\", \"content\": \"YOUR PROMPT\"}] }" #+end_src There are two bits of information needed in each request. The API key, which you must get from [[https://openai.com/][OpenAI]], and the prompt text itself (i.e. whatever you want ChatGPT to help you with). The results are not too shabby. #+ATTR_HTML: :width 80% [[file:images/a-chatgpt-emacs-shell/chatgpt.gif]] I've uploaded the code to GitHub as a tiny [[https://github.com/xenodium/chatgpt-shell][chatgpt-shell]] package.

If you're looking for ways to present from Emacs itself, David's post is well worth a look. org-present's spartan but effective approach resonated with me. David's touches bring the wonderfully stylish icing to the cake. I personally liked his practice of collapsing slide subheadings by default. This lead me to think about slide navigation in general... There were two things I wanted to achieve: 1. Easily jump between areas of interest. Subheadings, links, and code blocks would be a good start. 2. Collapse all but the current top-level heading within the slide, as navigation focus changes. A quick search for existing functions led me to =org-next-visible-heading=, =org-next-link=, and =org-next-block=. While these make it easy to jump through jump between headings, links, org block on their own, I wanted to jump to whichever one of these is next (similar a web browser's tab behaviour). In a way, [[https://en.wikipedia.org/wiki/DWIM][DWIM]] style. I wrapped the existing functions to enable returning positions. This gave me =ar/rg-next-visible-heading-pos=, =ar/rg-next-link-pos=, and =ar/rg-next-block-pos= respectively. Now that I can find out the next location of either of these items, I can subsequently glue the navigation logic in a function like =ar/org-present-next-item=. To restore balance to the galaxy, I also added =ar/org-present-previous-item=. #+begin_src emacs-lisp :lexical no (defun ar/org-present-next-item (&optional backward) "Present and reveal next item."

This is specially useful for SwiftUI. I didn't bother too much with inserting symbols themselves since I hadn't figured out a way to render them for all buffers. That's now changed. Christian Tietze and Alan Third both have useful posts in this space: - [[http://idiocy.org/emacs-fonts-and-fontsets.html][Emacs, fonts and fontsets]] - [[https://christiantietze.de/posts/2023/01/use-sf-pro-for-sf-symbols-everywhere-in-emacs/][Use San Francisco Font for SF Symbols Everywhere in Emacs]] I'm currently using the following to render SF symbols in all buffers (macOS only): #+begin_src emacs-lisp :lexical no ;; Enable rendering SF symbols on macOS.

Once I find a symbol I'm happy with, I copy its name and paste it into my Swift source. This works fairly well. With Christian Tietze recently posting [[https://christiantietze.de/posts/2022/12/sf-symbols-emacs-tab-numbers/][how he rendered SF Symbols in Emacs]], I figured there may be a way to shift the above workflow to rely on Emacs completion instead. While I initially went down a rabbit hole to programmatically extract SF symbols (via something like [[https://github.com/SFSafeSymbols/SFSafeSymbols][SFSafeSymbols]]), I took a step back to rethink the strategy. From the [[https://developer.apple.com/sf-symbols/][SF Symbols app]], one can select multiple symbols and copy/paste either the symbols themselves or their respective names. The catch is you can only copy disjointed data. That is, you can copy the symbols or their names, but not both in one go. Let's take a look at what the disjointed data looks like. I've pasted both under separate sections in an Emacs buffer. #+ATTR_HTML: :width 60% :height 60% [[file:images/emacs-macro-me-some-sf-symbols/disjointed.png]] If I could rejoin these two sets, I would have a lookup table I could easily invoke from Emacs. There are roughly 4500 symbols, so copying, pasting, along with text manipulation isn't manually feasible. Lucky for us, an Emacs [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Keyboard-Macros.html][keyboard macro]] is the perfect hammer for this nail. You can see the macro in action below. #+ATTR_HTML: :width 60% :height 60% [[file:images/emacs-macro-me-some-sf-symbols/mini-macro_x1.6.webp]] This looks fairly magical (and it is), but when you break it down into its building blocks, it's nothing more than recording your keystrokes and replaying them.

We are now at a strategic location where we can replay the above commands. To start/end recording and executing keyboard macros, use: - C-x ( :: [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Basic-Keyboard-Macro.html][kmacro-start-macro]] - C-x ) :: [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Basic-Keyboard-Macro.html][kmacro-end-macro]] - C-x e :: [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Basic-Keyboard-Macro.html][kmacro-end-and-call-macro]] runs your macro.

While Tree-sitter can enable faster and more reliable syntax-highlighting in our beloved text editor, it can also power smarter tools. It does so by exposing a semantic snapshot of our source code using a syntax tree. Let's see how we can use Tree-sitter to realise our original yasnippet vision. We'll start with the same struct snippet we used back in 2020.

It's pretty handy for opening files using an external app (ie. not Emacs) other than the default macOS one. =dwim-shell-commands-macos-open-with= and =dwim-shell-commands-open-externally= are typically enough for me to handle opening files outside of Emacs. But every now and then I'd like to change the default macOS app associated with specific file types. Now this isn't particularly challenging in macOS, but it does require a little navigating to get to the right place to change this default setting. Back in March 2020, I [[https://twitter.com/xenodium/status/1242879439932923909][tweeted]] about [[https://github.com/moretension/duti][duti]]: a command-line utility capable of setting default applications for various document types on macOS.

I've been revisiting lots of my command-line usages (specially those that never stuck) and making them more accessible from Emacs via [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]]. I seldom change default apps on macOS, so my brain forgets about =duti= itself, let alone its arguments, order, etc. But with a dwim shell command like =dwim-shell-commands-macos-set-default-app=, I can easily invoke the command via [[https://github.com/abo-abo/swiper][swiper]]'s =counsel-M-x= fuzzy terms: /"dwim set"/. #+ATTR_HTML: :width 95% :height 95% [[file:images/hey-emacs-change-the-default-macos-app-for/set-default_x1.3.webp]] As an added bonus, I get to reuse =dwim-shell-commands--macos-apps= from "open with" to quickly pick the new default app, making the whole experience pretty snappy. #+begin_src emacs-lisp :lexical no (defun dwim-shell-commands-macos-set-default-app () "Set default app for file(s)."

I wanted to know where the photo was taken, which got me interested in extracting [[https://en.wikipedia.org/wiki/Exif][Exif]] metadata. Luckily the [[https://exiftool.org/][exiftool]] command line utility does the heavy lifting when it comes to extracting metadata. Since I want it quickly accessible from Emacs (in either dired or current buffer), a tiny elisp snippet would give me just that (via [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]]). #+ATTR_HTML: :width 95% :height 95% [[file:images/hey-emacs-where-did-i-take-that-photo/dwim-exif_x1.3.webp]] #+begin_src emacs-lisp :lexical no (defun dwim-shell-commands-image-exif-metadata () "View EXIF metadata in image(s)."

I've made some small tweaks, but here's the gist of it: #+begin_src emacs-lisp :lexical no (defun dwim-shell-commands-feh-marked-files () "View all marked files with feh." (interactive) (dwim-shell-command-on-marked-files "View with feh" "feh --auto-zoom --scale-down '<<*>>'" :silent-success t :utils "feh")) (defun dwim-shell-commands-dragon-marked-files () "Share all marked files with dragon."

Are there new magical command-line utilities out there I don't know about? In this instance, I got to learn about [[https://feh.finalrewind.org/][feh]] and [[https://github.com/mwh/dragon][dragon]]. [[https://feh.finalrewind.org/][feh]] is a no-frills image viewer for console users while [[https://github.com/mwh/dragon][dragon]] is a simple drag-and-drop source/sink for X or Wayland. Both utilities are great uses of =dwim-shell-command=, enabling a seamless transition from Emacs to the /outside world/. These days I'm rarely on a linux box, so I was keen to ensure macOS had these cases covered. [[https://en.wikipedia.org/wiki/Preview_(macOS)][Preview]] is a solid macOS equivalent to [[https://feh.finalrewind.org/][feh]]. =Preview= is already macOS's default image viewer. A simple =open '<>'= would do the job, but if we'd like to make this command more portable, we can accomodate as follows: #+begin_src emacs-lisp (defun dwim-shell-commands-open-externally () "Open file(s) externally." (interactive) (dwim-shell-command-on-marked-files "Open externally" (if (eq system-type 'darwin) "open '<>'" "xdg-open '<>'") :silent-success t :utils "open")) #+end_src Special mention goes to Bozhidar Batsov's [[https://github.com/bbatsov/crux][crux]] which achieves similar functionality via =crux-open-with=. [[https://github.com/bbatsov/crux][crux]] provides a bunch of other useful functions. Some of my favourites being =crux-duplicate-current-line-or-region=, =crux-transpose-windows=, =crux-delete-file-and-buffer=, and =crux-rename-buffer-and-file=, but I digress. Moving on to a [[https://github.com/mwh/dragon][dragon]] equivalent on macOS, I thought I had it covered via [[https://github.com/kaz-yos/reveal-in-osx-finder][reveal-in-osx-finder]] or [[https://github.com/jcs-elpa/reveal-in-folder][reveal-in-folder]]. Turns out, neither of these reveal multiple [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Dired.html][dired]]-selected files within [[https://en.wikipedia.org/wiki/Finder_(software)][Finder]]. At first, I thought this could be easily achieved by passing additional flags/params to macOS's =open= command, but it doesn't seem to be the case. Having said that, this [[https://stackoverflow.com/questions/7652928/launch-finder-window-with-specific-files-selected][Stack Overflow post]], has a solution in Objective-C, which is where things got a little more interesting. You see, back in July I [[https://xenodium.com/emacs-dwim-shell-command-multi-language/][added multi-language support]] to [[https://xenodium.com/emacs-dwim-shell-command-multi-language/][dwim-shell-command]] and while it highlighted language flexibility, I hadn't yet taken advantage of this feature myself. That is, until today. The Objective-C snippet from the Stack Overflow post can be written as a Swift one-liner. Ok I lie.

I wanted to forward the menu to others but figured I should probably send it as a single file. ImageMagick's [[https://imagemagick.org/script/convert.php][convert]] command-line utility works great for this purpose. Feed it some images and it creates a pdf for you: #+begin_src sh convert image1.png image2.png image3.png combined.pdf #+end_src Using =convert= for this purpose was pretty straightforward. I'm sure I'll use it again in a similar context, but what if I can make future usage more seamless? In the past, I would just make a note of usage and revisit when needed. Though this works well enough, it often requires some amount of manual work (looking things up, tweaking command, etc) if you happen to forget the command syntax. I wanted common one-liners (or [[https://xenodium.com/png-to-icns-emacs-dwim-style/][longer shell scripts]]) to be easily reusable and accessible from Emacs. Turns out, the [[https://github.com/xenodium/dwim-shell-command][dwim-shell-command]] experiment is working fairly well for this purpose. In addition to providing template expansion, it generally [[https://xenodium.com/emacs-dwim-shell-command/][tries to do what I mean]] (focus when needed, reveal new files, rename buffers, etc). Here's how I saved the =convert= command instance for future usage: #+begin_src emacs-lisp :lexical no (defun dwim-shell-commands-join-as-pdf () "Join all marked images as a single pdf." (interactive) (dwim-shell-command-on-marked-files "Join as pdf" "convert -verbose '<<*>>' '<>'" :utils "convert")) #+end_src From now on, any time I'd like to join multiple files into a pdf, I can now select them all and invoke =dwim-shell-commands-join-as-pdf=. #+ATTR_HTML: :width 90% :height 90% [[file:images/seamless-command-line-utils/joined_minimal_x1.2.webp]] In the saved command, ='<<*>>'= expands to either [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Dired.html][dired]] selected files or whatever file happens to be open in the current buffer. The buffer file isn't of much help for joining multiple items, but can be handy for other instances (say I want to convert current image to jpeg). Moving on to ='<>'=, we could have just written as =joined.pdf=, but wrapping it ensures the resulting file name is unique. That is, if =joined.pdf= already exists, write =joined(1).pdf= instead. These kinds of command-line integrations are working well for me. Take the webp animation above, it was created by invoking =dwim-shell-commands-video-to-webp= on a =.mov= file. Easy peasy. While I can easily memorize the =convert= command for the pdf instance, I'm hopeless in the webp scenario: #+begin_src sh ffmpeg -i '<>' -vcodec libwebp -filter:v fps=fps=10 -compression_level 3 -lossless 1 -loop 0 -preset default -an -vsync 0 '<>'.webp #+end_src While searching through command line history helps to quickly re-spin previous commands, it requires remembering the actual utility used for any particular action.

I give it a .zip file and it unzips it for me. No flags or arguments to remember (for my typical usages anyway). Most importantly, I've fully internalized the =unzip= command into muscle memory, probably because of its /perfect mnemonic/. But then there's .tar, .tar.gz, .tar.xz, .rar, and a whole world of compression archives, often requiring different tools, flags, etc. and I need to remember those too. Can't remember where I got this "life hack" from, but it suggests something along the lines of... #+begin_center /Once you find a lost item at home, place it in the first spot you looked./ #+end_center Great, I'll find things quickly.

Certainly brings challenges if you can't modify the environment on the remote machine. The severity would depend on how frequently you have to do this. Fortunately for me, it's infrequent. Additionally, if accessing remote machine via [[https://www.gnu.org/software/emacs/manual/html_mono/eshell.html][eshell]], this is a non-issue.

I know. It's a little naughty. Going with it for now. I used to use "extract" (also in comments), which I still like but somehow "unzip" still wins my memory race. [[https://lobste.rs/s/qaimmg/lifehack_for_your_shell#c_73bzze][There's also "x"]] (nice option), which seems to originate from [[https://github.com/sorin-ionescu/prezto][prezto]]. I could consider unzipp, unzip1, or some other variation. Not sure how I missed this, but there's also an [[https://lobste.rs/s/qaimmg/lifehack_for_your_shell#c_ra6sbf][existing alias for atool]]: aunpack. Could be a great alternative. *** Pause before extracting archives Valid [[https://lobste.rs/s/qaimmg/lifehack_for_your_shell#c_73bzze][point]]. In my case, the pause typically happens /before/ I invoke the alias. *** Littering If the archive didn't have a root dir, it can [[https://lobste.rs/s/qaimmg/lifehack_for_your_shell#c_7fsart][litter your current directory]]. Indeed a pain to clean up. For this, we can atool's =--subdir= param to /always create subdirectory when extracting/. *** Alias to retrain [[https://lobste.rs/s/qaimmg/lifehack_for_your_shell#c_yr1jby][Neat trick]]: =alias unzip = “echo ‘use atool’”= to help retrain yourself.

Emacs being hyper-configurable, we can always teach it more things, so it can do exactly what we mean. There are no shortages of buffer searching packages for Emacs. I'm a fan of Oleh Krehel's [[https://github.com/abo-abo/swiper][swiper]], but before that, I often relied on the built-in [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Basic-Isearch.html][isearch]]. Swiper is my default goto mechanism and have it bound to =C-s= (replacing the built-in [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Basic-Isearch.html][isearch-forward]]). Swiper services most needs until I start combining with other tools. Take [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Keyboard-Macros.html][keyboard macros]] and [[https://github.com/magnars/multiple-cursors.el][multiple cursors]]. Both wonderful, but neither can rely on swiper to do their thing. Ok, swiper does, but [[https://xenodium.com/emacs-swiper-and-multiple-cursors/][in a different way]]. Rather than binding =C-s= to swiper, let's write a DWIM function that's aware of macros and multiple cursors. It must switch between swiper, isearch, and [[https://github.com/avkoval/phi-search][phi-search]] depending on what I want (search buffer, define macro, or search multiple cursors). Let's also tweak swiper's behavior a little further and prepopulate its search term with the active region. Oh, and I also would like swiper to wrap around (see [[http://oremacs.com/swiper/][ivy-wrap]]). But only swiper, not other ivy utilities. I know, I'm picky, but that's the whole point of DWIM... so here's my function to search forward that does exactly what ✨I✨ mean: #+begin_src emacs-lisp :lexical no (defun ar/swiper-isearch-dwim () (interactive) ;; Are we using multiple cursors?

Let's write an equivalent to search backwards.

In my case, I really enjoyed reading the entire book. I liked its narrative, mixing _actionable_ and _concrete_ advice with personal stories and experiments. After reading Atomic Habits during the first lockdown, I was excited to try out its actionables, specially tracking to keep me honest. I tried a bunch of iOS apps, but wanted no friction, no tracking, no cloud, no social, no analytics, no account, etc. so eventually [[https://xenodium.com/frictionless-org-habits-on-ios/][built Flat Habits]] ([[https://flathabits.com][flathabits.com]]). Also wanted to own my habit data (as plain text), so I made sure Flat Habits stored its data locally as an org file. I'm an Emacs nutter and can say the strength in habit tracking lies in removing daily friction from the tracking process itself. A quickly accessible mobile app can really help with that. For me, Emacs plays a less important role here. The plain text part is cherry on top (bringing piece of mind around lock-in). In my case, it's been months since I looked at the plain text file itself from an Emacs org buffer. The iOS app, on the other hand, gets daily usage. As for forming lasting habits (the actual goal here)... it's been well over a year since I started running as a regular form of exercise. While reading Atomic Habits really changed how I think of habits, a tracker played a crucial part in the daily grind. I happen to have built a tracker that [[https://xenodium.com/flat-habits-meets-org-agenda/][plays nice with Emacs]]. It's a new year. If you're looking at forming new habits, you may want some inspiration and also practical and concrete guidance. The book Atomic Habits can help with that. You can decide on which apps and how to implement the tracking process later on. Pen and paper is also a viable option and there are plenty of templates you can download. There's a surplus of habit-tracking apps on the app stores. I built yet another one for iOS, modeled after my needs. #+BEGIN_EXPORT html

#+END_EXPORT * [2021-11-28 Sun] Emacs bends again :PROPERTIES: :CUSTOM_ID: emacs-bends-again :END: While adding more rendering capabilities to [[https://plainorg.com][Plain Org]], it soon became apparent some sort of screenshot/snapshot testing was necessary to prevent regressing existing features. That is, we first generate a rendered snapshot from a given org snippet, followed by some visual inspection, right before we go and save the blessed snapshot (often referred to as golden) to our project. Future changes are validated against the golden snapshot to ensure rendering is still behaving as expected. Let's say we'd like to validate table rendering with links, we can write a test as follows: #+begin_src swift func testTableWithLinks() throws { assertSnapshot( matching: OrgMarkupText.make( """ | URL | Org link | |------------------------+-------------| | https://flathabits.com | [[https://flathabits.com][Flat Habits]] | | Regular text | Here too | |------------------------+-------------| """), as: .image(layout: .sizeThatFits)) } #+end_src The corresponding snapshot golden can be seen below. #+ATTR_HTML: :width 50% [[file:images/emacs-bends-again/testTableWithLinks.1.png]] This is all done rather effortlessly thanks to [[https://twitter.com/pointfreeco][Point Free]]'s wonderful [[https://github.com/pointfreeco/swift-snapshot-testing][swift-snapshot-testing]] utilities. So what does any of this have to do with Emacs? You see, as I added more snapshot tests and made modifications to the rendering logic, I needed a quick way to visually inspect and override all goldens. All the main pieces were already there, I just needed some elisp glue to /bend Emacs my way™./ First, I needed to run my Xcode builds from the command line. This is already [[https://developer.apple.com/library/archive/technotes/tn2339/_index.html][supported via xcodebuild]]. Next, I needed a way to parse test execution data to extract failing tests. [[https://twitter.com/davidahouse][David House]]'s [[https://github.com/davidahouse/xcodebuild-to-json][xcodebuild-to-json]] handles this perfectly. What's left? Glue it all up with some elisp. Beware, the following code snippet is packed with assumptions about my project, it's messy, surely has bugs, can be optimized, etc. But the important point here is that Emacs is such an amazing malleable power tool. Throw some elisp at it and you can to bend it to your liking. After all, it's _your_ editor. And so here we are, I can now run snapshot tests from Emacs using my hacked up ~plainorg-snapshot-test-all~ function and quickly override (or ignore) all newly generated snapshots by merely pressing y/n keys. Oh, and our beloved web browser was also invited to the party. Press "d" to open two browser tabs if you'd like to take a closer look (not demoed below).

I use [[https://orgmode.org/worg/org-contrib/babel/intro.html][org babel]] too. Oh and [[https://orgmode.org/manual/Tracking-your-habits.html][org habits]]. My never-ending list of TODOs is also powered by org. I manage all of this from Emacs and peek at TODOs using [[https://orgmode.org/manual/Agenda-Views.html][org agenda]]. This all works really well while I'm sitting in front of my laptop running Emacs. But then I'm away from my laptop... and I need to quickly record habits on the go. I need it to be low-friction. Ssh'ing to an Emacs instance from a smartphone isn't an option. I'm an iPhone user, so whatever the solution, it should play nice with Emacs and org mode. I built [[https://flathabits.com][Flat Habits]] for habit tracking and I'm fairly happy with the result.

This is handy for the few times I want to transition from Emacs to Finder for file management. I say few times since Emacs's directory editor, [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Dired.html][dired]], is just awesome. I've written about dired customizations [[https://xenodium.com/showhide-emacs-dired-details-in-style/][here]] and [[https://xenodium.com/showhide-emacs-dired-details-in-style/][here]], but since dired is /just another buffer,/ you can apply your Emacs magic like multiple cursors to [[https://xenodium.com/batch-renaming-with-counsel-find-dired-and-wdired/][batch rename files in an editable dired buffer]]. To transition from macOS Finder to Emacs, Christian offers an Emacs interactive command that fetches Finder's location and opens a dired buffer via AppleScript. On a similar note, I learned from redditor [[https://www.reddit.com/user/pndc/][u/pndc]] that [[https://www.reddit.com/r/emacs/comments/ohgz0s/open_macos_finder_windows_path_in_dired/h4p8a8f?utm_source=share&utm_medium=web2x&context=3][Finder's proxy icons can be dragged over to Emacs]], which handily drops ya into a dired buffer. With these two solutions in mind, I looked into a third one to offer a context menu option in Finder to show the file in Emacs. This turned out to be fairly easy using Automator, which I've rarely used. #+ATTR_HTML: :width 50% :height 50% [[file:images/show-in-finder--show-in-emacs/show_in_emacs.gif]] I created a flow that runs a shell script to "Show in Emacs", revealing the selected file or folder in an dired buffer. This is similar to Christian's solution, but invoked from Finder itself. The flow also uses /dired-goto-file/ which moves the point (cursor) to the file listed under dired. #+ATTR_HTML: :width 98% :height 98% [[file:images/show-in-finder--show-in-emacs/show_in_emacs.png]] #+begin_src sh current_dir=$(dirname "$1") osascript -e 'tell application "Emacs" to activate' path/to/emacsclient --eval "(progn (dired \"$current_dir\") (dired-goto-file \"$1\"))" #+end_src As a bonus, I added an "Open in Emacs" option, which does as it says on the tin. Rather than show the file listed in a dired buffer, it gets Emacs to open it in your favorite major mode. This option is not technically needed since Finder already provides an "Open With" context menu, but it does remove a few click here and there. #+ATTR_HTML: :width 98% :height 98% [[file:images/show-in-finder--show-in-emacs/open_in_emacs.png]] #+begin_src sh osascript -e 'tell application "Emacs" to activate' /Users/alvaro/homebrew/bin/emacsclient --eval "(find-file \"$1\")" #+end_src On a side note, Emacs defaults to creating new frames when opening files via "Open With" menu (or "open -a Emacs foo.txt").

The author highlights Emacs's ability to apply additional logic when replacing text during a search-and-replace session. It does so by leveraging elisp expressions. Coincidentally, a redditor recently asked [[https://www.reddit.com/r/emacs/comments/o878am/what_is_the_simplest_way_to_apply_a_math_formula/][What is the simplest way to apply a math formula to all numbers in a buffer/region?]] Some of the answers also point to /search and replace/ leveraging elisp expressions. While I rarely need to apply additional logic when replacing matches, it's nice to know we have options available in our Emacs toolbox. This prompted me to check out [[https://github.com/emacs-mirror/emacs/blob/b8f9e58ef72402e69a1f0960816184d52e5d2d29/lisp/replace.el#L709][replace-regexp]]'s documentation (via M-x [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Name-Help.html][describe-function]] or my favorite M-x [[https://github.com/Wilfred/helpful][helpful-callable]]). There's lots in there. Go check its docs out. You may be pleasantly surprised by all the features packed under this humble function. For instance, \& expands to the current match. Similarly, \#& expands to the current match, fed through [[https://www.gnu.org/software/emacs/manual/html_node/elisp/String-Conversion.html][string-to-number]]. But what if you'd like to feed the match to another function? You can use \, to signal evaluation of an elisp expression. In other words, you could multiply by 3 using \,(* 3 \#&) or inserting whether a number is odd or even with something like \,(if (oddp \#&) "(odd)" "(even)"). Take the following text: #+begin_example 1 2 3 4 5 6 #+end_example We can label each value "(odd)" or "(even)" as well as multiply by 3, by invoking /replace-regexp/ as follows: #+begin_quote M-x replace-regexp #+end_quote [PCRE] Replace regex: #+begin_quote [-0-9.]+ #+end_quote Replace regex [-0-9.]+: #+begin_quote \& \,(if (oddp \#&) "(odd)" "(even)") x 3 = \,(* 3 \#&) #+end_quote #+begin_example 1 (odd) x 3 = 3 2 (even) x 3 = 6 3 (odd) x 3 = 9 4 (even) x 3 = 12 5 (odd) x 3 = 15 6 (even) x 3 = 18 #+end_example It's worth noting that /replace-regexp/'s cousin [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Query-Replace.html][query-replace-regexp]] also handles all this wonderful magic.

Fast-forward to June 2021 and Scott Nicholes [[https://github.com/zweifisch/ob-swift/issues/4#issuecomment-858196354][reminded me there's still interest]] in org babel SwiftUI support. ob-swift [[https://github.com/zweifisch/ob-swift/commits/master][seems a little inactive]], but no worries there. The package offers great general-purpose Swift support. On the other hand, SwiftUI previews can likely live as a single-purpose package all on its own... and so I set off to bundle the rendering functionality into a new [[https://github.com/xenodium/ob-swiftui][ob-swiftui]] package. Luckily, org babel's documentation has a straightforward section to help you [[https://orgmode.org/worg/org-contrib/babel/languages/index.html][develop support for new babel languages]]. They simplified things by offering [[https://code.orgmode.org/bzg/worg/raw/master/org-contrib/babel/ob-template.el][template.el]], which serves as the foundation for your language implementation. For the most part, it's a matter of searching, replacing strings, and removing the bits you don't need. The elisp core of ob-swiftui is fairly simple. It expands the org block body, inserts the expanded body into a temporary buffer, and finally feeds the code to the Swift toolchain for execution. #+begin_src emacs-lisp (defun org-babel-execute:swiftui (body params) "Execute a block of SwiftUI code in BODY with org-babel header PARAMS. This function is called by `org-babel-execute-src-block'" (message "executing SwiftUI source code block") (with-temp-buffer (insert (ob-swiftui--expand-body body params)) (shell-command-on-region (point-min) (point-max) "swift -" nil 't) (buffer-string))) #+end_src The expansion in /ob-swiftui--expand-body/ is a little more interesting. It decorates the block's body, so it can become a fully functional and stand-alone SwiftUI macOS app. If you're familiar with Swift and SwiftUI, the code should be fairly self-explanatory. From an org babel's perspective, the expanded code is executed whenever we press /C-c C-c/ (or M-x [[https://orgmode.org/manual/The-Very-Busy-C_002dc-C_002dc-Key.html#The-Very-Busy-C_002dc-C_002dc-Key][org-ctrl-c-ctrl-c]]) within the block itself. It's worthing mentioning that our new implementation supports two babel [[https://www.orgmode.org/worg/org-contrib/babel/header-args.html][header arguments]] (results and view). Both extracted from params using [[https://github.com/emacs-mirror/emacs/blob/3af9e84ff59811734dcbb5d55e04e1fdb7051e77/lisp/emacs-lisp/map.el#L106][map-elt]] and replaced in the expanded Swift code to enable/disable snapshotting or explicitly setting a SwiftUI root view. #+begin_src emacs-lisp (defun ob-swiftui--expand-body (body params) "Expand BODY according to PARAMS and PROCESSED-PARAMS, return the expanded body."

He writes about [[https://blog.vivekhaldar.com/post/3996068979/the-levels-of-emacs-proficiency][the levels of Emacs proficiency]]. All 6 levels are insightful in their own right, but for the sake of this post, let's quote an extract from level /4. Shell inside Emacs/: #+begin_quote "And then, you learned about it: M-x shell. It was all just text. Why did you need another application for it? Why should only the shell prompt be editable? Why can’t I move my cursor up a few lines to where the last command spewed out its results? All these problems simply disappear when your shell (or shells) simply becomes another Emacs buffer, upon which all of the text manipulation power of Emacs can be brought to bear." #+end_quote In other words, we aren't merely removing shell restrictions, but opening up possibilities...

Don't think I remember what the command itself was, but what's important here is that [[https://en.wikipedia.org/wiki/DWIM][DWIM]] stands for [[https://en.wikipedia.org/wiki/DWIM][do what I mean]]. I love DWIM interactive commands. They enable commands to be smarter and thus pack more functionality, without incurring the typical cognitive overhead associated with remembering multiple commands (or key bindings). The Emacs manual does a great job describing DWIM for the [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Comment-Commands.html][comment-dwim]] command: #+begin_src The word “dwim” is an acronym for “Do What I Mean”; it indicates that this command can be used for many different jobs relating to comments, depending on the situation where you use it. #+end_src It's really great to find built-in DWIM-powered Emacs commands. Third-party packages often include them too. I typically gravitate towards these commands and bind them in my Emacs config. Examples being upcase-dwim, downcase-dwim, or mc/mark-all-dwim. But what if the DWIM command doesn't exist or the author has written a command for what /they/ mean? This is your editor, so you can make it do what /you/ mean. Take for example, [[https://orgmode.org/manual/Handling-Links.html][org-insert-link]], bound to /C-c C-l/ by default. It's handy for inserting [[https://orgmode.org/guide/Hyperlinks.html][org mode links]]. I used it so frequently that I quickly internalized its key binding. Having said that, I often found myself doing some lightweight preprocessing prior to invoking /org-insert-link/. What if I can /make org-insert-link do what I mean/? ** What do I mean? *** Use URLs when in clipboard If the URL is already in the clipboard, don't ask me for it. Just use it. *** Use the region too If I have a region selected and there's a URL in the clipboard, just sort it out without user interaction. #+ATTR_HTML: :width 50% :height 50% [[file:images/emacs-dwim-do-what-i-mean/link-this-text.gif]] *** Automatically fetch titles Automatically fetch URL titles from their HTML tag, but ask me for tweaks before insertion. #+ATTR_HTML: :width 50% :height 50% [[file:images/emacs-dwim-do-what-i-mean/do-what-i-mean.gif]] *** Fallback to org-insert-link If my DWIM rules don't apply, fall back to using good ol' [[https://orgmode.org/manual/Handling-Links.html][org-insert-link]].

I use it to dissect these wonderful references more effectively. You see, I wrote this command [[https://xenodium.com/get-emacs-to-gather-links-in-posts/][back in 2015]]. We can likely revisit and improve. The [[https://github.com/zweifisch/enlive][enlive]] package continues to do a fine job [[https://github.com/zweifisch/enlive/blob/604a8ca272b6889f114e2b5a13adb5b1dc4bae86/enlive.el#L39][fetching]], parsing, and [[https://github.com/zweifisch/enlive/blob/604a8ca272b6889f114e2b5a13adb5b1dc4bae86/enlive.el#L142][querying]] HTML. Let's improve my code instead... we can shed a few redundant bits and maybe use [[https://xenodium.com/modern-elisp-libraries/][newer libraries and features]]. Most importantly, let's improve the user experience by sanitizing and filtering URLs a little better. We start by writing a function that looks for a URL in the clipboard and subsequently fetches, parses, and extracts all links found in the target page. #+begin_src emacs-lisp (require 'enlive) (require 'seq) (defun ar/scrape-links-from-clipboard-url () "Scrape links from clipboard URL and return as a list. Fails if no URL in clipboard." (unless (string-prefix-p "http" (current-kill 0)) (user-error "no URL in clipboard")) (thread-last (enlive-query-all (enlive-fetch (current-kill 0)) [a]) (mapcar (lambda (element) (string-remove-suffix "/" (enlive-attr element 'href)))) (seq-filter (lambda (link) (string-prefix-p "http" link))) (seq-uniq) (seq-sort (lambda (l1 l2) (string-lessp (replace-regexp-in-string "^http\\(s\\)*://" "" l1) (replace-regexp-in-string "^http\\(s\\)*://" "" l2)))))) #+end_src Let's chat /(current-kill 0)/ for a sec. No improvement from my previous usage, but let's just say building interactive commands that work with your current clipboard (or [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Kill-Ring.html][kill ring]] in Emacs terminology) is super handy (see [[https://xenodium.com/emacs-clone-git-repo-from-clipboard/][clone git repo from clipboard]]). Moving on to sanitizing and filtering URLs... Links often have trailing slashes. Let's flush them. [[https://github.com/emacs-mirror/emacs/blob/3af9e84ff59811734dcbb5d55e04e1fdb7051e77/lisp/emacs-lisp/subr-x.el#L261][string-remove-suffix]] to the rescue. This and other handy string-manipulating functions are built into Emacs since 24.4 as part of [[https://github.com/emacs-mirror/emacs/blob/master/lisp/emacs-lisp/subr-x.el][subr-x.el]]. Next, we can keep http(s) links and ditch everything else. The end-goal is to extract links posted by users, so these are typically fully qualified external URLs. [[https://github.com/emacs-mirror/emacs/blob/3af9e84ff59811734dcbb5d55e04e1fdb7051e77/lisp/emacs-lisp/seq.el][seq-filter]] steps up to the task, included in Emacs since 25.1 as part of the [[https://github.com/emacs-mirror/emacs/blob/master/lisp/emacs-lisp/seq.el][seq.el family]]. We remove duplicate links using [[https://github.com/emacs-mirror/emacs/blob/3af9e84ff59811734dcbb5d55e04e1fdb7051e77/lisp/emacs-lisp/seq.el#L431][seq-uniq]] and sort them via [[https://github.com/emacs-mirror/emacs/blob/3af9e84ff59811734dcbb5d55e04e1fdb7051e77/lisp/emacs-lisp/seq.el#L255][seq-sort]]. All part of the same package. When sorting, we could straight up use /seq-sort/ and /string-lessp/ and nothing else, but it would separate http and https links. Let's not do that, so we drop /http(s)/ prior to comparing strings in /seq-sort/'s predicate. [[https://github.com/emacs-mirror/emacs/blob/3af9e84ff59811734dcbb5d55e04e1fdb7051e77/lisp/subr.el#L4468][replace-regexp-in-string]] does the job here, but if you'd like to skip regular expressions, [[https://github.com/emacs-mirror/emacs/blob/3af9e84ff59811734dcbb5d55e04e1fdb7051e77/lisp/emacs-lisp/subr-x.el#L255][string-remove-prefix]] works just as well. Yay, sorting no longer cares about http vs https: #+begin_src https://andymatuschak.org http://antirez.com https://apenwarr.ca/log ... #+end_src With all that in mind, let's flatten list processing using [[https://github.com/emacs-mirror/emacs/blob/3af9e84ff59811734dcbb5d55e04e1fdb7051e77/lisp/emacs-lisp/subr-x.el#L69][thread-last]]. This isn't strictly necessary, but since this is the 2021 edition, we'll throw in this macro added to Emacs in 2016 as part of 25.1. Arthur Malabarba has a [[https://endlessparentheses.com/new-in-emacs-25-1-more-flow-control-macros.html][great post on thread-last]].

The catalyst: reading James Clear's wonderful [[https://jamesclear.com/atomic-habits][Atomic Habits]] (along with plenty of lock-down inspiration). As much as I live in Emacs and org mode, it just wasn't practical enough to rely on my laptop for tracking habits.

I've been using the app every day with success. The habits seem to be sticking, but equally important, it's been really fun to join the fabulous world of Emacs/Org with iOS/SwiftUI.

That's all fine, but what I'd really like is a quick way to toggle between my preferred two choices: /Standard/ and /270°/. Unsurprisingly, I'd also like to invoke it as an interactive command via Emacs's /M-x/ (see [[http://xenodium.com/emacs-connect-my-bluetooth-speaker/index.html][Emacs: connect my Bluetooth speaker]]).

No biggie, but why go through the same steps every time? We can do better. We have a hyper malleable editor, so let's get it to grab the URL from clipboard and do its thing. /shell-command/ or /async-shell-command/ can help in this space, but require additional work: change location, re-type command, what if directory already exists...

Jacob Rus's [[http://www.hcs.harvard.edu/~jrus/site/cocoa-text.html][Customizing the Cocoa Text System]] offers a more in-depth picture and also shows how to customize global macOS keybindings (via DefaultKeyBinding.dict). In addition to moving Emacs [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Point.html][point]] (cursor) up/down using C-p/C-n, I've internalized the same bindings to select an option from a list. Good Emacs examples of these are [[https://company-mode.github.io/][company mode]] and [[https://github.com/abo-abo/swiper][ivy]]. Vertical cursor movement using Emacs bindings works well in most macOS apps, including forms and text boxes in web pages. However, selecting from a completion list doesn't quite work as expected.

It's been roughly a week since I started using the Karabiner remapping, and I've yet to find a case where a web page (or any other macOS app) did not respond to c-p and c-n to move selection from a list. #+ATTR_HTML: :width 75% :height 75% [[file:images/improved-ctrl-p-ctrl-n-macos-movement/bindings-fixed.gif]] My ~/.config/karabiner/karabiner.json configuration is as follows: #+begin_src json { "global": { "check_for_updates_on_startup": true, "show_in_menu_bar": true, "show_profile_name_in_menu_bar": false }, "profiles": [ { "complex_modifications": { "parameters": { "basic.simultaneous_threshold_milliseconds": 50, "basic.to_delayed_action_delay_milliseconds": 500, "basic.to_if_alone_timeout_milliseconds": 1000, "basic.to_if_held_down_threshold_milliseconds": 500, "mouse_motion_to_scroll.speed": 100 }, "rules": [ { "description": "Ctrl+p/Ctrl+n to arrow up/down", "manipulators": [ { "from": { "key_code": "p", "modifiers": { "mandatory": [ "control" ] } }, "to": [ { "key_code": "up_arrow" } ], "conditions": [ { "type": "frontmost_application_unless", "bundle_identifiers": [ "^org\\.gnu\\.Emacs" ] } ], "type": "basic" }, { "from": { "key_code": "n", "modifiers": { "mandatory": [ "control" ] } }, "to": [ { "key_code": "down_arrow" } ], "conditions": [ { "type": "frontmost_application_unless", "bundle_identifiers": [ "^org\\.gnu\\.Emacs" ] } ], "type": "basic" } ] } ] }, "devices": [], "fn_function_keys": [], "name": "Default profile", "parameters": { "delay_milliseconds_before_open_device": 1000 }, "selected": true, "simple_modifications": [], "virtual_hid_keyboard": { "country_code": 0, "mouse_key_xy_scale": 100 } } ] } #+end_src ** Bonus (C-g to exit) Pressing Esc often dismisses or cancels macOS windows, menus, etc. This is also the case for web pages.

It can be easily integrated into other tools for rapid experimentation. Being a SwiftUI noob, I could use some SwiftUI integration with my editor of choice. With some elisp glue and a small patch, Chris's snippet can be used to generate SwiftUI inline previews using Emacs org babel. This is particularly handy for playing around with SwiftUI layouts. We can piggyback ride off zweifisch's [[https://github.com/zweifisch/ob-swift][ob-swift]] by advicing /org-babel-execute:swift/ to inject the org source block into the bootstrapping snippet. We also add a hook to /org-babel-after-execute-hook/ to automatically refresh the inline preview. If you're a [[https://github.com/jwiegley/use-package][use-package]] user, the following snippet should make things fairly self-contained (if you have [[https://melpa.org/][melpa]] set up already). #+begin_src emacs-lisp (use-package org :hook ((org-mode . org-display-inline-images)) :config (use-package ob :config (use-package ob-swift :ensure t :config (org-babel-do-load-languages 'org-babel-load-languages (append org-babel-load-languages '((swift . t)))) (defun ar/org-refresh-inline-images () (when org-inline-image-overlays (org-redisplay-inline-images))) ;; Automatically refresh inline images.

We introduced the /:swiftui/ header param to switch between inline static /preview/ and /interactive/ mode. To try out an inline /preview/, create a new org file (eg. swiftui.org) and a source block like: #+begin_src org :exports src ,#+begin_src swift :results file :swiftui preview VStack(spacing: 10) { HStack(spacing: 10) { Rectangle().fill(Color.yellow) Rectangle().fill(Color.green) } Rectangle().fill(Color.blue) HStack(spacing: 10) { Rectangle().fill(Color.green) Rectangle().fill(Color.yellow) } } .frame(maxWidth: .infinity, maxHeight: .infinity) ,#+end_src #+end_src #+begin_src org :exports src ,#+results: #+end_src [[file:images/swiftui-layout-previews-using-emacs-org-blocks/vstack.jpg]] Place the cursor anywhere inside the source block (#+begin_src/#+end_src) and press C-c C-c (or M-x org-ctrl-c-ctrl-c). To run interactively, change the /:swiftui/ param to /interactive/ and press C-c C-c (or M-x org-ctrl-c-ctrl-c). When running interactively, press "q" (without ⌘) to quit the Swift app. comments on [[https://twitter.com/xenodium/status/1194224168709083137][twitter]]. ** Update - Tweaked the snippet to make it more self-contained and made the steps more reproducible. Need to work out how to package things to make them more accessible. May be best to contribute as a patch to [[https://github.com/zweifisch/ob-swift][ob-swift]] and we can avoid the icky /advice-add/. - Thanks to Chris Eidhof for PNG support (instead of TIFF).

In Mike Zamansky's [[https://cestlaz.github.io/post/using-emacs-72-customizing-elfeed/][Using Emacs 72 - Customizing Elfeed]] video, he highlights a desire to open elfeed entries in the background. That is, open the current rss entry (or selected entries) without shifting focus from Emacs to your browser. This behaviour is somewhat analogous to ⌘-clicking/ctrl-clicking on multiple links in the browser without losing focus. I've been wanting elfeed to open links in the background for some time. Zamansky's post was a great nudge to look into it. He points to the relevant [[https://github.com/skeeto/elfeed/blob/58ab1f8bcc3014206db42a7a26f3120ba5de4ca6/elfeed-search.el#L783][elfeed-search-browse-url]] function, re-implemented to suit his needs. In a similar spirit, I wrote a function to open the current rss entry (or selected entries) in the background. I'm running macOS, so I took a look at [[https://github.com/emacs-mirror/emacs/blob/d714aa753b744c903d149a1f6c69262d958c313e/lisp/net/browse-url.el#L1018 I ][browse-url-default-macosx-browser]] to get an idea of how URLs are opened. Simple. It let's macOS handle it via the "open" command, invoked through /start process/. Looking at open's command-line options, we find /--background/ which "does not bring the application to the foreground." #+begin_src emacs-lisp open --background http://xenodium.com #+end_src "b" is already bound to /elfeed-search-browse-url/, so in our snippet we'll bind "B" to our new background function, giving us some flexibility: #+begin_src emacs-lisp (use-package elfeed :ensure t :bind (:map elfeed-search-mode-map ("B" . ar/elfeed-search-browse-background-url)) :config (defun ar/elfeed-search-browse-background-url () "Open current `elfeed' entry (or region entries) in browser without losing focus."

About a week ago, I built and installed its [[https://github.com/djcb/mu/releases/tag/1.3.10][pre-release version (1.3.10)]] and noted [[http://xenodium.com/building-mumu4e-on-macos/][build steps on macOS]]. It's been working great for me. Today, I updated to 1.4. I was keen to try the new release out. I had been experiencing a short delay immediately after syncing/indexing mail. An initial investigation pointed to contact syncing, but I didn't dig further. The 1.4 release notes had a promising entry: #+begin_quote In many cases, `mu4e' used to receive /all/ contacts after each indexing operation; this was slow for some users, so we have updated this to /only/ get the contacts that have changed since the last round. #+end_quote After upgrading. The delay is gone for me \o/ *Note*: there are a few config tweaks needed for the 1.4 upgrade, but these are well-documented in the [[https://github.com/djcb/mu/releases/tag/1.4][release notes]]. For me, it primarily consisted of: - Swapping elisp /mu4e-maildir/ var for /mu init --maildir path/to/local/IMAP/. - Swapping elisp /mu4e-user-mail-address-list/ for /mu init --my-address address1@domain.com --my-address address2@domain.com/. - Disabling /mu4e-maildirs-extension/ (not yet compatible with mu 1.4). No issues here, since I hardly ever look at the /mu4e-main/ buffer.

Turns out, you can prepend the search query with additional switches using the "--" separator. The switches are usually utility-specific, but if we wanted to keep results from file names matching a glob, we can prepend the ripgrep query with something like /"--glob Make* --"/ or the shorter version /"-g Make* --"/. rg: -g Make* -- install #+ATTR_HTML: :width 75% :height 75% [[file:images/enhanced-emacs-searching-with-counsel-switches/counsel-rg-switch.gif]] * [2019-11-10 Sun] Emacs org block company completion :PROPERTIES: :CUSTOM_ID: emacs-org-block-company-completion :END: UPDATE: This is now available [[https://melpa.org/#/company-org-block][on melpa]]. Back in 2015, I bound the "<" key to a hydra for quickly inserting org blocks. The idea came from Oleg's post on [[https://oremacs.com/2015/03/07/hydra-org-templates/][org-mode block templates in Hydra]]. The suggested binding settled in my muscle memory without much effort. Fast forward to Febrary 2019. I replaced the hydra with /[[https://orgmode.org/manual/Easy-templates.html][org-insert-structure-template]]/ when /org-try-structure-completion/ was removed from org mode. No biggie, as I kept the same binding to "<" and hardly noticed the change. Since my primary use-case for easy templates is inserting [[https://orgmode.org/manual/Working-with-source-code.html][source blocks]], I was keen to expedite choosing the source language as well as inserting the source block itself. Writing a small [[https://company-mode.github.io/][company mode]] completion backend fits my primary use-case pretty well. #+ATTR_HTML: :width 50% :height 50% [[file:images/emacs-org-block-company-completion/company-org-block.gif]] The company backend looks as follow (*Warning:* [[https://twitter.com/tpanum/status/1197772426072997888][Snippet needs Org v9.2]]).

Invoking /M-n/ in /shell-command/'s prompt is handy for quickly getting the current buffer's file name. This works great for one-off shell commands like /"chmod +x script.sh"/ or /"tidy -xml -i -m data.xml"/. Unfortunately, these commands aren't easily reusable from /shell-command/'s minibuffer history, since it'll keep hardcoded file names. There's likely existing built-in functionality or a more elaborate package for this, but advising /read-shell-command/ enables us to write more reusable commands like /"chmod +x $f"/ or /"tidy -xml -i -m $f"./ We merely replace /$f/ with /(buffer-file-name)/, and let everything else continue as usual. #+ATTR_HTML: :width 50% :height 50% [[file:images/more-reusable-emacs-shell-command-history/expanded-shell-command.png]] #+begin_src emacs-lisp (defun ar/adviced-read-shell-command (orig-fun &rest r) "Advice around `read-shell-command' to replace $f with buffer file name."

You can subsequently use all your favorite file-editing tricks to rename files (amongst other things). You can see it in action at the end of [[http://emacsrocks.com/e16.html][Emacs Rocks episode 16]]. When combining [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Dired-and-Find.html][find-dired]] with wdired, one can easily find matching files and quickly batch rename them using something like [[https://github.com/magnars/multiple-cursors.el][multiple cursors]] or [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Keyboard-Macros.html][keyboard macros]]. I've been a fan of the /find-dired/ -> /dired-toggle-read-only/ -> /mc/mark-all-like-this/ workflow for quite some time, but I always wished I could adjust /find-dired/ queries a little quicker by getting immediate feedback. Completion frontends like [[https://github.com/abo-abo/swiper][ivy]] and [[https://github.com/emacs-helm/helm][helm]] are perfect for getting this kind of immediate feedback. Peeking into ivy's [[https://github.com/abo-abo/swiper/blob/master/counsel.el][counsel source]], I borrowed some ideas to glue counsel-style narrowing on a find command, which I can easily translate to a writeable dired buffer for all that joyful-mutiple-cursor-editing experience. #+ATTR_HTML: :width 50% :height 50% [[file:images/batch-renaming-with-counsel-find-dired-and-wdired/counsel-find.gif]] The code for /ar/counsel-find/ is a little rough but can be found at [[https://github.com/xenodium/dotsies/blob/master/emacs/ar/ar-counsel-find.el][here]]. * [2019-04-26 Fri] VPS bookmarks :PROPERTIES: :CUSTOM_ID: vps-bookmarks :END: - [[https://www.scaleway.com][Scaleway: Scalable Cloud Platform Designed for Developers]]. - [[https://www.vultr.com][Vultr]]. * [2019-04-22 Mon] Svelte bookmarks :PROPERTIES: :CUSTOM_ID: svelte-bookmarks :END: - [[https://svelte.dev/blog/svelte-3-rethinking-reactivity][Svelte 3: Rethinking reactivity]]. - [[https://svelte.dev/blog/write-less-code][Write less code (metric you're not paying attention to)]]. * [2019-04-16 Tue] Mark region, indent, restore location :PROPERTIES: :CUSTOM_ID: mark-region-indent-restore-location :END: When I'm not using an automatic code formatter (ie. clang-format, gofmt, etc.), I often find myself using Emacs region marking commands like /mark-defun/, /er/expand-region/, and /mark-whole-buffer/ prior to pressing , which is bound to /indent-for-tab-command/. This is all working as expected: the selection gets indented and the point is left in the current location. Say we have the following snippet we'd like to indent. [[file:images/mark-region-indent-restore-location/before.png]] Mark region with C-M-h (mark-defun) [[file:images/mark-region-indent-restore-location/selection.png]] Indent with (indent-for-tab-command) [[file:images/mark-region-indent-restore-location/basic-indent.png]] We're done. The selected function is now indented as expected. But... I always wished the point returned to the location prior to initiating the region-marking command, in this case /mark-defun/. In short, I wish the point had ended in the following location. [[file:images/mark-region-indent-restore-location/smart-indent.png]] I'm not aware of an existing package that helps with this, so here's a tiny minor mode (divert-mode) to help with restoring point location after indenting a region.

Now let's wire up two org source blocks to fetch the data and subsequently plot using gnuplot. It's pretty neat. You can take the output from one source block and use it as input to another. We use curl to fetch data from fitbit's API and pipe through [[https://stedolan.github.io/jq/][jq]] and sed to massage the output format into two columns. *Note:* Before using gnuplot in org babel, you'll need to install the gnuplot package and add to babel languages. #+BEGIN_SRC emacs-lisp (use-package gnuplot :ensure t) (use-package ob :config (org-babel-do-load-languages 'org-babel-load-languages '((gnuplot . t)))) #+END_SRC #+NAME: weight-data #+BEGIN_SRC sh :results table curl -s -H "Authorization: Bearer TOKEN" https://api.fitbit.com/1/user/USER_ID/body/weight/date/2018-06-09/2018-07-11.json | jq '.[][] | "\(.dateTime) \(.value)"' | sed 's/"//g' #+END_SRC #+RESULTS: weight-data | 2018-06-09 | 65.753 | | 2018-06-10 | 65.762 | | 2018-06-11 | 65.771 | | 2018-06-12 | 65.78 | | 2018-06-13 | 65.789 | | 2018-06-14 | 65.798 | | 2018-06-15 | 65.807 | | 2018-06-16 | 65.816 | | 2018-06-17 | 65.825 | | 2018-06-18 | 65.85 | | 2018-06-19 | 65.96 | | 2018-06-20 | 64.1 | | 2018-06-21 | 65.64 | | 2018-06-22 | 65.47 | | 2018-06-23 | 65.515 | | 2018-06-24 | 65.56 | | 2018-06-25 | 65.605 | | 2018-06-26 | 65.65 | | 2018-06-27 | 65.18 | | 2018-06-28 | 64.49 | | 2018-06-29 | 64.49 | | 2018-06-30 | 64.41 | | 2018-07-01 | 64.33 | | 2018-07-02 | 64.25 | | 2018-07-03 | 64.17 | | 2018-07-04 | 64.55 | | 2018-07-05 | 64.39 | | 2018-07-06 | 64.33 | | 2018-07-07 | 65.06 | | 2018-07-08 | 63.28 | | 2018-07-09 | 63.4 | | 2018-07-10 | 64.22 | | 2018-07-11 | 63.95 | Now feed the two column data to gnuplot. #+BEGIN_SRC gnuplot :var data=weight-data :exports code :file images/fitbit-api-org-babel-and-gnuplot/weight.png reset set title "My recent weight" set xdata time set timefmt '%Y-%m-%d' set format x "%d/%m/%y" set term png set xrange ['2018-06-09':'2018-07-11'] plot data u 1:2 with linespoints title 'Weight in Kg' #+END_SRC #+RESULTS: #+ATTR_HTML: :width 75% :height 75% [[file:images/fitbit-api-org-babel-and-gnuplot/weight.png]] Fetching data and plotting through org babel and gnuplot is pretty sweet.

I have a few workflows using Emacs's [[https://github.com/emacs-helm/helm][Helm]] framework. There are great productivity boosters like [[https://www.alfredapp.com/][Alfred]] and [[https://qsapp.com/][Quicksilver]] for macOS, with batteries included. If you're a tinkerer, you'd enjoy the powerful [[http://hammerspoon.org/][Hammerspoon]]. Like elisp gluing all things Emacs, Hammerspoon uses Lua to glue all things macOS. You can build your own narrowing utilities using [[http://www.hammerspoon.org/docs/hs.chooser.html][chooser]] and a little Lua. #+BEGIN_SRC local chooser = hs.chooser.new(function(choice) hs.alert.show(choice['text']) end) chooser:choices({ { ["text"] = "Alfred\n", ["subText"] = "macOS only\n", }, { ["text"] = "Quicksilver\n", ["subText"] = "macOS only\n", }, { ["text"] = "Hammerspoon\n", ["subText"] = "macOS only\n", }, { ["text"] = "Emacs\n", ["subText"] = "is everywhere :)\n", }, }) chooser:show() #+END_SRC #+ATTR_HTML: :width 75% :height 75% [[file:images/emacs-utilities-for-your-os/chooser.png]] Howard Abrams's post on [[http://howardism.org/Technical/Emacs/capturing-content.html][Capturing Content for Emacs]] inspired me to look at gluing Emacs and macOS to launch my own cross-platform narrowing utilities. I've also taken this opportunity to look at Oleh Krehel's wonderful completion package: [[https://github.com/abo-abo/swiper][Ivy]]. We can use it to build a macOS narrowing utility. Ivy is remarkably easy to use. Turns out, [[http://oremacs.com/swiper/#api][ivy-read]] is all you need. A simple Emacs completion can be accomplished with little elisp. #+BEGIN_SRC emacs-lisp (ivy-read "Hello ivy: " '("One " "Two " "Three " "Four ")) #+END_SRC #+ATTR_HTML: :width 50% :height 50% [[file:images/emacs-utilities-for-your-os/simple_ivy.png]] Pretty nifty. Let's make this completion more accessible from the rest of the OS. To do so, we create a separate Emacs frame and make it pretty. We also want it to interact with the OS. We'll use /ivy-read/'s /:action/ to invoke a tiny bit of AppleScript. Oh and we'll also use some funny quotes to tease ourselves about our beloved editor. #+BEGIN_SRC emacs-lisp (with-current-buffer (get-buffer-create "*modal-ivy*") (let ((frame (make-frame '((auto-raise . t) (background-color .

I wrote a utility to extract all links from [[https://raw.githubusercontent.com/xenodium/xenodium.github.io/master/index.org][this page's org file]] and make them easily searchable from anywhere on macOS by invoking *⌥-W*. The keys are bound using Lua, Hammerspoon, and emacsclient. This works well on macOS, but there are alternatives for other operating systems. #+BEGIN_SRC hs.execute("emacsclient -ne \""..elisp.."\" -s /tmp/emacs*/server") #+END_SRC Here's the resulting utility in action: #+ATTR_HTML: :width 100% :height 100% [[file:images/emacs-utilities-for-your-os/ivy_links.gif]] These integrations look promising.

That’s Good]], I was encouraged to expand my emotional vocabulary. As a [[https://github.com/emacs-mirror/emacs/blob/master/lisp/play/zone.el][zone.el]] fan (checkout [[https://github.com/wasamasa/zone-nyan][nyan]], [[https://github.com/kawabata/zone-sl][sl]], and [[https://github.com/kawabata/zone-rainbow][rainbow]]), I looked into writing a zone [[https://github.com/emacs-mirror/emacs/blob/master/lisp/play/zone.el#L52][program]]. When /zone-when-idle/ is set, zone acts as a screensaver of sorts. We can use this to display random emotional vocab whenever Emacs is idle for a period of time. Let's get to it... Zone keeps a list of programs to choose from when kicked off. Below is a basic /zone-hello/ program, along with an interactive command for previewing. Not much to these. The tiny program prepares the screen for zoning and inserts text while no input is pending. #+BEGIN_SRC emacs-lisp (defun zone-hello () (delete-other-windows) (setq mode-line-format nil) (zone-fill-out-screen (window-width) (window-height)) (delete-region (point-min) (point-max)) (goto-char (point-min)) (while (not (input-pending-p)) (insert "hello zone\n") (zone-park/sit-for (point-min) 0.2))) (defun zone-hello-preview () (interactive) (let ((zone-programs [zone-hello])) (zone))) #+END_SRC Here's what /zone-hello/ looks like: #+ATTR_HTML: :width 75% :height 75% [[file:images/emacs-and-emotional-vocab/minimal-zone.gif]] Back to improving our emotional vocabulary, we'll need a dictionary for our goal.

We can use [[http://wordnet.princeton.edu/][WordNet]] to define them while offline. These two sources will do for now.

Saving the [[http://www.theguardian.com/lifeandstyle/wordofmouth/2011/feb/10/how-cook-perfect-chocolate-fondants][The Guardian's recipe]]: ** Ingredients (2 servings) - 60g unsalted butter, cut into dice, plus extra to grease - 1 tbsp cocoa powder - 60g dark chocolate, broken into pieces - 1 egg and 1 egg yolk - 60g caster sugar - 1 tbsp plain flour ** Preparation 1. Pre-heat the oven to 200C if cooking immediately, and put a baking tray on the middle shelf. Butter the inside of 2 small ramekins or pudding moulds, and then put the cocoa in one and turn it to coat the inside, holding it over the second mould to catch any that escapes. Do the same with the other mould. 2. Put the butter and chocolate into a heatproof bowl set over, but not touching, a pan of simmering water and stir occasionally until melted. Allow to cool slightly. 3. Vigorously whisk together the egg, yolk, sugar and a pinch of salt until pale and fluffy. Gently fold in the melted chocolate and butter, and then the flour. Spoon into the prepared moulds, stopping just shy of the top – at this point the mixture can be refrigerated until needed, or even frozen, as the puddings will not wait around once cooked. 4. Put on to a hot baking tray and cook for 12 minutes (14 if from cold, 16 if frozen) until the tops are set and coming away from the sides of the moulds. Leave to rest for 30 seconds and then serve in the ramekins or turn out on to plates if you're feeling confident – they're great with clotted cream or plain ice cream. * [2016-01-20 Wed] Parenting bookmarks :PROPERTIES: :CUSTOM_ID: parenting-bookmarks :END: :MODIFIED: [2021-07-03 Sat] :END: - [[http://www.janetlansbury.com/2018/07/a-toddlers-do-it-myself-attitude-ends-in-tantrums/][A Toddler's Do-It-Myself Attitude Ends In Tantrums - Janet Lansbury]]. - [[https://news.ycombinator.com/item?id=17023693][Ask HN: Any good collaboratively built documentation on good parenting?

It's a wonderful source of Emacs tips. Having just finished the ebook on my Kindle, I was keen to go back and fish out some of that newly found wisdom. My immediate reaction was to figure out a way to make the ebook searchable from Emacs. The ebook is available in epub and pdf format. Though Emacs's docview is super handy for viewing pdf's, searching didn't feel as comfortable as searching in org mode. The epub, on the other hand, proved useful. [[http://pandoc.org][Pandoc]] can easily convert from epub to org. #+BEGIN_SRC sh pandoc --from=epub --to=org mastering-emacs.epub > mastering-emacs.org #+END_SRC After a some tidying (mostly removing BEGIN_HTML/END_HTML blocks and adding TITLE/AUTHOR), the resulting org file is surprisingly clean and easy to search/navigate.
