Language Server Protocol support

[gnull]

Hey!

I see that texpresso supports multiple different editors via ad-hoc plugins made separately for each one. Would it make sense to unify the interface and provide texpresso as an LSP?

This way, it would trivially work with many different editors with no need to add support one-by-one. And the LSP interface seems sufficient for texpresso's functionality.

Hi,

The existing protocol does the job quite well, and it allows for cheap experimentation with Vim/Emacs. It would not make sense to remove it in my opinion, but adding LSP as an alternative protocol could be a good idea. I don't have the time to do this, but it would be welcome as a contribution.

However, I am thinking that adding support for TeXpresso to an existing LSP server, likely https://github.com/latex-lsp/texlab, is maybe the way to go. TeXpresso can only provide a subset of the features expected from an LSP server.
A dedicated LSP server like TeXlab can make better decision about what features to expose, and when to use TeXpresso and when to use other sources of information.
