math-delimiters VS vertico

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.

It would be great if you add your snippet to the Vertico wiki. Such tweaks can be quite instructive for others who want to achieve the same or similar effects for other completion commands.

If you want completion to be sorted by your "most recent" I suggest you have a look at completion libraries. One example is vertico; when you enable savehist mode, the variable magit-revision-history, containing the branches you visited is persisted between sessions and vertico use that offer completions by most-recently-used, by default.

I think vertico is best alternative recently, really fast on Linux, macOS and Windows.

(use-package modus-themes :vc (:url "https://gitlab.com/protesilaos/modus-themes" :branch "main")) (use-package vertico :vc (:url "https://github.com/minad/vertico" :rev :newest :lisp-dir "extensions/"))

An example relevant to your list would be some changes many people are taking with their completion framework - using package that leverage core emacs functionality rather than replacing it with a complete package that 'overrides' it. Consult, vertico, orderless and associate packages come to mind here. If you do a bit of a search you'll find plenty of info. Here is a video from Prot on the subject, but there are many others as well. I think Prot actually went on to write his own completion system to overlay native emacs functionality as well.

Next you "only" have to remember (elisp) function names. "Completion UIs" like ivy/counsel, icomplete, helm or vertico/consult, give you a nice auto completion list on M-x (choose the one of them, you like the most). Some of those Completion UIs will display existing keybindings and a short documentation for commands, near the auto complete candidates. So you will start to remember more keybindings without "learning sessions", just because invoking functions via keybindings is much faster (more convenient).

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.

I thought that lsp and rtags were different tools to do different things. Regarding lsp, I configured lsp-mode in my init file indeed! Currently I'm using Vertico (plus recommended sub-packages at github repository) and lsp-mode.

Hey! There has already been a horizontico.el. ;)

FYI, selectrum is getting deprecated in favor of vertico. https://github.com/minad/vertico/issues/237
