[FEATURE] Improve neovim support about jayvee HOT 4 OPEN

This sounds like a really nice extension, even though most of it is in projects we have no control over (e.g. vim)? From what I see, for us this would mean:

• Automatically build a standalone language server executable (stretch goal of publishing it as well)
• Provide syntax highlighting. Langium generates TextMate and Monarch grammars, would any of these work? I am unfamiliar with how they relate to treesitter but Monarch is used for VSCode syntax highlighting for example.

Yes, but in case of vim and nvim-lspconfig a plugin can accomplish the same without a noticeable difference. So we are not dependent on our changes getting merged there.

Langium generates TextMate and Monarch grammars, would any of these work?

I found this plugin. It looks into the VSCode extension directory and uses the textmate grammars there to highlight the file in neovim. This means that both VSCode and our extension for it need to be installed in order for syntax highlighting in neovim to work. It's a little janky but it does work.

I think we'd have an okay time setting up a buildstep that exports textmate grammars and the lsp executable on their own. That would free these files up from the VSCode extension. I think that would be a step that would make integration into neovim more elegant, right?

from jayvee.

The problem is that nvim-textmate doesn't support loading the grammar from a specific file. It only supports VSCode extensions. It may be possible to create a hacky solution where vscode doesn't have to be installed, but I can't say how much effort that would be.
