use-package VS lsp-mode

Another way would be to redefine parts of the bind-key macro or its use-package support functions

The package-install call installs use-package that provides a utility of the same name to make it easier to manage packages. It's admittedly a little overkill for this specific config, but it's a cheap investment that sets you up for later success.

Granted, the Doom macro makes your code looks nice and compact. But you can get very close to that just by using do-list and define-key together. Or by using the bind-key.el package, which is included with Use-package.

This strikes me as a contradiction, because if it was well documented you wouldn’t need to look at other people’s configs to see how to use it.

My experience with deps.edn is that every time I start a project and make a deps.edn file, I immediately draw a blank and don’t know how to structure it, so I open ones from other projects to start lifting stuff out of them.

I still don’t know how to reliably configure a project to use nrepl or socket repl without just using an editor plugin. I definitely have no idea how to use those in conjunction with a tool like reveal.

To me, none of that is simple. Simple would be like Emacs’ use-package. With that I know how to add dependencies, specify keybinds, and do initialization and configuration off the top of my head. And it has really nice documentation with tons of examples.

Since you are doing code development, the first things to go for would be setting up your emacs packaging (installing use-package and melpa (use-package's documentation covers this) so you have more packages to choose from (do be careful to not just pick things willy nilly but research them a bit first)) and then setting up lsp-mode. lsp-mode lets you use LSP servers for the specific programming languages you work with in a somewhat unified fashion. You then need to install and setup the LSP servers for the languages you use, and possibly install language specific Emacs packages as support (note, Emacs has builtin functionality for many).

I'm using use-package as my package manager and the package ligature for the ligatures.

I have been crafting my emacs config for about 10 years. I started with vanilla and intentionally stayed away from frameworks. About two years ago I declared config bankruptcy and went down for a rewrite using use-package and straight.

ref: https://github.com/radian-software/straight.el https://github.com/jwiegley/use-package

use-package! is a macro over use-package, and respect its syntax, with a few additions. Useful reference on use-package keywords.

I also tried to the solutions suggested  and , but nothing worked. I moved the (setq lsp-keymap-...) line outside (and before) use-package. I also used :config (define-key lsp-load-map...) in my use-package block. But none of them worked.

Not sure how much this might help, but lsp-mode has lsp-yaml-select-buffer-schema and lsp-yaml-set-buffer-schema commands to pick schema from a list or set from a URI. Checking the source of them might give some hints about how the same could be implemented in eglot?

Beyond that you might as well embrace the suck and install autex with a language server: https://emacs-lsp.github.io/lsp-mode/

Smart completion these days is done primarily through LSP. eglot is fairly minimal but built-in as of 29, also available via GNU Elpa. lsp-mode is another option with more integrations and a bit more fleshed out.

lsp-mode: https://github.com/emacs-lsp/lsp-mode/issues/2080

Are you running emacs-29? It has numerous speed-ups compared to emacs-28 and older versions, many of them coded by Mattias Engdegård, e.g. commit def6fa4246. I have a fresh build of emacs-29 running on Linux and a new mac with an M1 CPU, and it's stupid fast. I don't use the native-comp feature. I rarely notice any hesitation or slowness. I don't use Elpy. I do use lsp mode.

And first of all, I'm trying to understand, how is it connected to https://github.com/emacs-lsp/lsp-mode? I'm sure, that existed lsp implementations already parse source code. Why TreeSitter?
