So now that she's eating "real" food again, we took some of the curry we've been making lately to my mother. I was very happy to learn that she enjoyed it. Mind you, we're competing with hospital food, so it's not like the bar is terribly high.


I find the notion of an "off-grid" YouTuber to be... confusing.

God, my tab completion function is a hacky mess:
(defun lambdamoo-tab-complete ()
  "Complete user input using text from the buffer"
  (interactive)
  (when (memq (char-before) '(?  ?\r ?\n ?\t ?\v))
    (user-error "Point must follow non-whitespace character"))
  (let (replace-start
        (replace-end (point))
        replace-text found-pos found-text)
    (save-excursion
      (backward-word)
      (setq replace-start (point)
            replace-text (buffer-substring replace-start replace-end))
      (when (or (null lambdamoo--search-text)
                (not (string-prefix-p lambdamoo--search-text replace-text t)))
        (setq-local lambdamoo--search-text replace-text)
        (set-marker lambdamoo--found-point (point)))
      (goto-char lambdamoo--found-point)
      (unless
          (setq found-pos
                (re-search-backward
                 (concat "\\b" (regexp-quote lambdamoo--search-text))
                 (point-min) t))
        (setq-local lambdamoo--found-point (make-marker))
        (user-error "No match found"))
      (set-marker lambdamoo--found-point found-pos)
      (forward-word)
      (setq found-text (buffer-substring found-pos (point))))
    (delete-region replace-start replace-end)
    (insert found-text)))

@Omar Antolín Actually, looking more closely at it, it might just do the trick.

I love it when I spend hours re-writing code that essentially already exists. ;)

In the end, I wound up just binding tab to dabbrev-expand. 🙃

It might seem like I wasted a bunch of time writing that, but at least I learned a bunch along the way.

Me realizing that festival uses a Lisp dialect:

Oh cool, I can add accessibility features to my Emacs stuff by procedurally generating the code in elisp.


Me realizing that festival's symbols are case sensitive:

Welp, I guess I can just do
(defun festival-saytext (text)
  (format "(SayText %S)" text))
and do the rest of the processing in elisp directly. That's probably all I wanted anyway.



Hey all,

I have a friend who's been trying to get on Mastodon but tells me that it doesn't seem to play well with screen readers. I know there are plenty of people on the fedi who do use screen readers, but I have no experience with them myself, so I can't really direct him.

Can someone who does use a #ScreenReader point me in the direction of some resources that might be useful?

@Brailly615 In another comment it has been said that its about Linux, there I unfortunately can't help. I use Webclients, unfortunately they don't get any Updates anymore or I'd have recommended something. I only use them because I haven't found something better yet that I don't need to install. @Clio09 @C3nC3 @me @MonaApp @pachli

medical, vague ST:SNW spoiler

Was loading stuff onto my Jellyfin server for my mom to watch in the hospital. She liked Star Trek and I thought Strange New Worlds might be a good idea because it's a more fun show than a lot of the other recent Trek shows.

I started watching the first episode to be sure it was working, and realized I'd forgotten the whole thing about what happens with Captain Pike.

...maybe this show isn't the vibe after all...

When a #neurodivergent person tells you about how something is difficult for them, rather than thinking of them as whiny, consider that this probably means they have a certain level of trust in you to drop their mask enough to do so.

Invalidating that struggle is likely also a pretty effective way of eroding that trust.

@Sonikku All too freaking common.

A good boss should reduce or remove barriers that impede their subordinates from doing their job effectively. Shockingly few can actually accomplish this.

elisp question

I just put a call to eval in my code and I feel dirty now.

The context went something like this:

(eval (cons 'concat (my-function arg1 arg2)))

I had initially hoped to use
(concat . (my-function arg1 arg2))

...but this resulted in a call to
(concat my-function arg1 arg2)

Which was not what I expected.

Is there a better way I could've written this?
#emacs #lisp #elisp

Edit: Got my answer. I wanted:

(apply 'concat (my-func arg1 arg2))

Edit 2:
It turns out the code I really wanted was:

(string-join arg2 arg1)

I love reinventing the wheel because I didn't know it was already there.

Edit 3:
Here's the actual code:

(defun lambdamoo-run-text-replacements (str)
  "Perform text replacements on the string"
  (dolist (vals lambdamoo-text-replacements)
    (let* ((from (car vals))
           (to (cdr vals))
           (split (split-string str from)))
      (setq str (string-join split to))))
  str)

Let's see if there's anything else I've reinvented here.

elisp question

@Simon Brooke What I was looking to do was to call concat with the list returned by (my-function arg1 arg2) used as arguments.

As it turns out, all the functionality I was looking for was already supplied by the string-join function. I just didn't know it existed.

in reply to Simon Brooke

elisp question
@Simon Brooke Also, I don't like calling eval unnecessarily, as it can open you up to security vulnerabilities if not done carefully.



I just wrote a bunch of #elisp code like this:
(catch :abort
  ;; do something
  (when condition
    (message "A bad thing happened")
    (throw :abort nil))
  ;; do something else
  )

When the functionality I really wanted was:
(progn
  ;; do something
  (when condition
    (user-error "A bad thing happened"))
  ;; do something else
  )

I knew the former felt sketchy, but I couldn't think of a better way to do it until just now.

One thing I miss in #Lisp coming from #Haskell is the ability to search for functions by their type signature. I hadn't realized how much I relied upon this ability until I lost it.
in reply to Jonathan Lamothe

As a Schemer (and formerly/sometimes still Objective-C), everything is pretty verbose, and my own functions even more so, so I can search by function name knowing the type and parameters. (vector-index vec searchfunc), (draw-rect-with-edge-color rect edge-width color), etc.

There's no excuse for hardcore Lisp functions like (wadsf w q) "wander down stack frames for word query" (fictional but not unlikely).
#lisp

#lisp


#Elisp logic:

All interned symbols can be found in a lookup table. This table is bound to the obarray symbol.

Hang on a minute...

I can only assume that the underlying C code has its own pointer to this table and the obarray symbol is only provided as a convenience for elisp functions that can't see this pointer?
#emacs #lisp

in reply to Jonathan Lamothe

No no, the obarray you see from elisp is the same one used by the reader. Elisp is an old-style Lisp here, and the obarray is a first-class thing: you can make a new one, rebind obarray, etc.

That's the sort of thing people don't do much anymore, but used to do. The documentation covers it reasonably well gnu.org/software/emacs/manual/…
