math-delimiters VS marginalia

math-delimiters. Provides a nice command to insert LaTeX math delimiters and to toggle between inline and display versions of them.

(use-package math-delimiters :vc (:url "https://github.com/oantolin/math-delimiters" :rev :newest))

I use the math-delimiters package for this. It has a command you bind to $. Pressing it once inserts \(\) and leves point in the middle. Pressing it a second time changes those to \[\]. If you had an active region at the time, it will wrap that region in the delimiters. If you press $ after the closing delimiter it will switch to the other kind of delimiter and will take care of tucking punctuation in or out. I use it both in Org and LaTeX buffers.

In terms of LaTeX entry, I make heavy use of CDLaTeX (config), math-delimiters, latex-change-env (expository blog post here), as well as aas (config) (as well as many macros, of course!). I also have a few interesting-ish functions that e.g. automatically insert dollars around single characters, so that writing long documents is more ergonomic; I've written about these things a little bit here (this also showcases the preview feature of AUCTeX, which I quite like), and here.

One more excellent tool for text input is /u/oantolin's math-delimiters package; it can be used to toggle from inline to display math (which is a feature that I've found myself using quite often while editing).

You may be interested in my math-delimiters package. It defines a command math-delimiters-insert which you should bind to $. That single command is all you need to insert math delimiters, toggle them between inline and display math, and wrap an active region in math delimiters. Thanks to a recent addition by u/slinchisl it even handles moving ending punctuation in and out of the delimiters when toggling between inline and display math.

Check out marginalia[1]. Whenever you press M-x, it will pop up a buffer showing all the commands (with most recent ones on top) along with their keybindings and a brief description of what they do.

Embark[2] is also cool. It will show all the possible commands relevant to where the cursor is at that moment. I bind it to C-c a.

Then there is Marginalia which is IMO essential

marginalia. Informative annotations for minibuffer completion candidates, co-written with u/minad-emacs.

Wow, interesting that my response is getting down voted. It seems not enough that I give away my work for free. Nevertheless I appreciate support from the community, as other Emacs package developers. The support is actually helpful. To clarify, publishing my configuration would translate into quite a bit of work, requiring separation of private and public bits.

marginalia for extra info in the minibuffer

There seems to be some problem with straight not correctly installing or updating compat. See these issues on Marginalia and Embark where straight seems to not install Compat.

Note that I contribute to Emacs core itself from time to time but the process is discussion-heavy and thus time consuming. If you are familiar with the completing-read API, you may know the annotation-function of completion tables. The name already tells that this function just adds annotations to the completion candidates. The Marginalia package (written by /u/oantolin and me) provides such annotations. A similar function is the group-function, which groups candidates in subsets and adds titles above the subsets. I wrote the patch which added this feature to Emacs. It is now supported by default completion, Icomplete, Vertico and maybe other UIs. The initial implementation was done in the earlier Selectrum package, and a little later in Vertico.

At the end of the year, I am happy to announce the stable Vertico 1.0 and Marginalia 1.0 releases. Vertico is a minimalist, yet flexible and responsive vertical completion UI. Marginalia provides helpful annotations for many completion contexts. Both packages have been solid for a while but I rather let things mature slowly. These releases finally put the stamp "stable" on these two packages. I expect the other members of the package suite to follow soon after. Both packages have been updated recently to support the newest Emacs 29 features. They are compatible with Emacs 27, 28 and the upcoming 29.

I) I started out trying to implement this using marginalia, like the consult commands, but quickly concluded that this wasn't the way to go here... please correct me if I'm wrong and there is more from these packages I could make use of. I also try to make use of as much of the citar codebase as possible, but have found it difficult so far: a lot seems too specific for bibliographic entries.

I can't find anything that seems to discuss them in detail, but Marginalia is a package that applies them widely in completion. And here is a simple example for customized file completion.
