math-delimiters VS affe

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.

and another one, from the author of consult/vertico/..., minad, is affe: https://github.com/minad/affe

Why does it not mention affe from u/minad-emacs? https://github.com/minad/affe

If you don't mind, I have a bit of an unrelated question for you: What are your thoughts on Emac's existing multithreading support? For a few weeks now, I'm trying to do something practical with them, and found that they at least enable one thing: accept-process-output can be done without blocking the main thread (I have an small example and I'm preparing a blog post). I'm asking because I stumbled upon this project of yours: https://github.com/minad/affe and thought that it would be easier to implement with threads (with all their limitations). It would require careful coding so that the heavier computations don't block or starve the main thread, but I think it's possible, and would result in smaller and more performant code.

I found [affe.el](https://github.com/minad/affe), but I don't want to add this package if doom supports this kind of feature.

The closest thing you're looking for is affe it just uses completing-read in an async manner. The filtering is also done async so there is no lag. It supports emacs' completion styles, e.g. you can couple it with orderless.

Affe provides an asynchronous fuzzy finder similar to the fzf command-line fuzzy finder, written in pure Elisp. A producer process is started in the background, e.g., find, fd or ripgrep. The output produced by this process is filtered by an external asynchronous Emacs process. The Emacs UI always stays responsive since the work is completely off-loaded to other processes. The results are presented in the minibuffer using Consult, which allows to quickly select from the available items.

You may want to try my Affe, the Asynchronous Fuzzy Finder for Emacs, which works similarly to fzf and is fast, since the file list is generated only once and the filtering is performed in an external process on all files. However there is also no support for flex sorting, only filtering as offered by orderless.
