cloudmacs VS lsp-mode

Things to note: - This is a very self-hosted type of method. You can store your notes in the cloud of course, but there's no "online Emacs" (whelp, nevermind, I stand corrected). - This is a very text-based environment. There are images and whatnot, but Emacs is fundamentally a bunch of text. This is a powerful thing, don't think of it as a downside. Text is the universal interface. - This is going to be a learning experience, both about a new tool and about yourself. You should walk away from Emacs with philosophical questions and a desire to convert the nonbelievers. - You will never feel comfortable using a normal computer again once you experience the pure bliss of a computing environment made just for you. - Do youself a favor and start with David Wilson's Emacs From Scratch series. If you follow that series all the way through, and make your own choices instead of just copying him, you'll be hooked by the end of it. DO NOT try to use Emacs raw and uncustomized, and shame anyone who tells you that you should. - You should look into keybindings, ergonomics, and human physiology (especially about hands). Regular computer stuff with a regular keyboard is hell on your hands, and Emacs will make it worse if you let it force it's arcane keybinds on you. Just define your own keybinds that work for you. Bonus points if you end up with a layered split vertical ortholinear concave thumb-cluster keyboard (I aint there yet because money, but I will eventually build my own custom keyboard).

If the goal is to have org mode running in a browser (even without wasm), then you could look at something like this: https://beepb00p.xyz/cloudmacs.html

In that last point there is Cloudmacs, which essentially runs spacemacs I'm docker and accessible via ssh within a browser.

Just kidding, you could try Cloudmacs. No idea how well it works with newer Emacs.

Maybe https://github.com/karlicoss/cloudmacs is what you're looking for?

Interesting side thought, there's also a Docker container for a browser-usable emacs that works by using gotty to render a tty (and the emacs running on it) in a webpage. So you could in theory have a container with both that and OCaml+opam, which would let you tuareg-mode, merlin, and the OCaml interactive mode within this browser-based emacs.

This reminds me of cloudmacs

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?
