Start language server for .langium grammar files

[borisbrodski]

I would like to use NeoVim for development. How to manually run language server for .langium grammar files?

(Should be straight forward, but I couldn't find it even after extensive web search)

Hey @borisbrodski,

you would need to extract the main.js from the vscode extension (or build it from scratch) and run the file using node main.js --stdio and connect the stdio with the language client. No idea how that works in NeoVim though. We just use the vscode-languageclient to get the support for VS Code.

Also, does NeoVim support textmate based syntax highlighting? We make heavy use of that to get the syntax highlighting in VS Code.

This works indeed. Thank you very much!

I just needed to fix one line in the code: #1590
