lsp-mode VS tide

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.

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).

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?

How does it compare with Tide? https://github.com/ananthakumaran/tide

I got to try my hands on Typescript in Emacs using tide, and I loved the autocompletion enabled by type-inference. But even besides type-inference, there's even the autocompletion for previously defined local variables that exists in other language tools including anaconda for python, which I don't see in my setup of SLIME/emacs.

You should try tide for TypeScript projects.

off topic: I've found tide-mode[0] to be pretty good to use with typescript on Emacs

Is there a way to autogen doxygen doc for C/C++? At least templates with the parameters types and return type? I do this with tide in Emacs with Typescript for example and it's pretty useful.

Anyone got any experience with this package? I have got it running but the default key binding to jump to a definition is not working at all. Stated here (https://github.com/ananthakumaran/tide) M-. should work but that seems to be already bound to something else.

Then I started with TypeScript and I was both amazed and saddened by it. For regular TS files, .ts it was amazing. The spacemacs typescript-mode was even better than rjsx-mode, all the types are shown perfectly in the bottom bar, autocomplete, auto-import... Everything. And thanks to tide. The sad part is: there is no tsx-mode, to write our .tsx files, we have to use web-mode. Don't get me wrong, this is a great mode, but React + Typescript were not the goals back then.
