LSP support

[MohrJonas]

Have you considered adding LSP support to babi? I was playing around a bit, trying to add it myself, but I'm no Python expert and I don't really understand the source code.

As far as I understand it, the main steps would be:

• [ ] Starting the correct language server when opening a file
  • [ ] Getting the file's language
  • [ ] Checking if a language server for that language is installed, if so start and connect to it
• [ ] When an edit occurs, let the language server know
• [ ] Watch for server messages about errors and warnings and show them to the user
• [ ] Watch for server messages about autocompletion and show them to the user
• [ ] When hovering the cursor over a symbol
  • [ ] Show information about that symbol provided by the language server
  • [ ] When a key is pressed, go to the definition
  • [ ] When a key is pressed, go to the implementation

There are already some LSP client implementations in Python, so there would be no need to start from scratch:

• pylspclient
• sansio-lsp-client

This of course is only a rough overview and by no means complete, but it would still be a huge step for babi Source

If you don't have the time / interest to implement LSP support, I'd of course be willing to do it myself and merge it into babe, but I would need some hints and pinpointing, regarding the already existing source code and how it works. Cheers

it's an absolute ton of work that I'm not interested in -- if you want to work on it by all means
