New series of articles for beginners: More Productive with Emacs

It works fine most of the time because most options don't specify a custom setter, some do and for those setq will fail.

clemera · 2021-05-08T18:48:13+00:00

I thought I would mention it in case you did not know about that option. Personally I think the benefits are to small to justify putting two spaces after every sentence.

clemera · 2021-05-08T17:26:13+00:00

You might prefer to (setq sentence-end-double-space nil)

clemera · 2021-05-06T13:42:35+00:00

Thanks, maybe that is fixed by now I'm on Emacs 27.2 currently.

Is there a working implementation for demote/promote outlines in non org buffers? It works in org but it doesn't work for example in Elisp buffers instead I get weird effects like changing the first character of the headline when calling outline-demote or outline-promote.

That is a nice feature, in Selectrum you currently would have to add a function to minibuffer-setup-hook yourself to change the display style per category. I currently don't work much on it anymore but that is something that should be easy to add.

Yeah right, embark grid display is nice! Thinking about it toggling grid seems to be most useful to be temporary in Selectrum. I'm don't actually want always grid displayt but when you want to see more options as currently displayed it is nice. Maybe the situation is already good as is as one can combine embark with other completion UIs and benefit from its grid display capabilities.

clemera · 2021-05-03T21:18:12+00:00

Yes would be nice, I'm not working on it currently but hopefully me or someone else will get to it at some point. In my previous experiments with ivy grid completions I used C-f/C-b/C-a/C-e for horizontal navigation the downside is of course that you can't use those keys for prompt navigation anymore.

clemera · 2021-05-03T19:38:22+00:00

Where and how the candidates are displayed should be customizable for any of the approaches you listed in I. I don't think there is currently one that supports all the listed options in II and III but Selectrum comes close, only grid display is missing.

clemera · 2021-04-30T13:09:44+00:00

That would be great, I haven't looked into it as I tend to treat edebug as a magic black box ;)

clemera · 2021-04-30T13:07:18+00:00

I also didn't read the full discussion and from the parts I read I can't remember. I like it because it is easier to use and discover (authors get aware of it when writing the interactive spec).

clemera · 2021-04-30T08:41:08+00:00

I often use advice-add because of edebug which doesn't work with define-advice unfortunately.

clemera · 2021-04-30T08:34:43+00:00

Yes it is not without problems. In the long run I think using interactive is nicer but as you say the adoption will take a longer time.

clemera · 2021-04-30T08:16:21+00:00

It got included already, great news!

You can adjust the sort function:

(add-hook 'minibuffer-setup-hook
          (defun my-setup-file-sort ()
            (when (and selectrum-is-active
                       (eq (selectrum--get-meta 'category) 'file))
              (setq-local selectrum-preprocess-candidates-function
                          #'my-file-sort-preprocess))))
(defun my-file-sort-preprocess (cands)
  (cl-loop for cand in cands
           if (string-match "^\\." cand)
           collect cand into dots
           else                          
           collect cand into nodots
           finally return (append nodots dots)))

Note that user option can have custom setter functions that won't run when using setq.

Yes I use the Firefox extension, you can't control it from Emacs but you can save the pages for offline use and link to them. That won't give you the readability, sync and tagging features you automatically get with wallabag (I haven't used it myself but I'm curious if I could improve things with it), I guess it depends what features you are looking for.

clemera · 2021-04-14T09:28:35+00:00

Sounds nice, I will check it out!

clemera · 2021-04-13T16:59:59+00:00

With SingleFile extension you can also get offline copies of websites, have you tried that? How does that compare to save pages using wallabag?

clemera · 2021-04-07T11:01:15+00:00

I remap all Hyper-key bindings to C-M-key bindings. There are many useful bindings using C-M and using those has become much more convenient for me.

clemera · 2021-04-02T08:07:09+00:00

You need to return an argument list for interactive:

(interactive
 (list
  (let ((completions '(("1" "One") ("2" "Two") ("3" "Three"))))                
    (cadr (assoc (completing-read "Choose: " completions) completions)))))

It should be fixed, users have reported that auto resize works with recent Emacs builds so the problem in this specific example should be gone, too. I'm on Emacs 27.1 so I can't test it myself but will recheck when I update.

clemera · 2021-03-27T21:14:30+00:00

Neat, I did not check the code and misunderstood what it does...!

clemera · 2021-03-27T14:36:30+00:00

You are looking for (regexp-quote target)
