* Python
|
|
|
|
Using the Microsoft language server as it's the best afaik. It's weird because it doesn't lookup the path to itself via PATH but has to be statically set.

* C/C++
|
|

This just requires hooking lsp onto ~c-mode~ and ~c++-mode~.

|

* Haskell
|
|
|
|
Enable ~haskell-mode~, and ~lsp-haskell~
|
|

#+BEGIN_SRC emacs-lisp

(use-package haskell-mode
|

:straight t

Disable the ~haskell-stack-ghc~ flycheck checker, it's not used when lsp starts, but it does get loaded just before it. Loading and unloading it is slow and causes Emacs to freeze for a few seconds, so just disable it.
