org-auctex VS math-delimiters

org-auctex: Async LaTeX preview support for Org-mode using AucTeX. Mostly deprecated since Org is getting a new async LaTeX preview system.

xenops looks quite interesting, I hadn't seen it before. I do also render my LaTeX maths in org, though with org-auctex instead of the default org-latex-preview (much faster!). The workflow is mostly that I write some maths inline to org, not inside of any source block—much less noise. When I'm done with a particular piece of code, I simply rerender the whole buffer; org-auctex is fast enough so that this doesn't take very long, even in dense org documents. The SVGs are automatically unprettified whenever you are inside them, so editing is seamless.

You can use most of the functionality of that blog post inside of Org. Things like cdlatex even have a special org-cdlatex-mode in order to be as unintrusive as possible, and for fast previews there is org-auctex (from the same author as the above post). Certainly things like autoexpanding snippets and other goodies work without a problem in Org.

Just a note that latex preview support for non-file-associated buffers (including elfeed/shr buffers) is still planned for org-auctex. (Time for Emacs has been really scant this year!)

For smoother latex previews in org you can try org-auctex. It's not done yet but I find it to be a big improvement.

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.
