How to install w/ language support via nix?

[nathan-at-least]

Hi, I run debian with nix installed.

So far I've been using hx built from source, and I've installed various LSP supports in an ad-hoc manner (without nix), and I'm regretting this. Not because of hg or different language plugins, they're awesome once configured! Instead it is because each LSP server uses various different implementation-specific packaging, so my "fully working hx configuration" is very non-reproducible and will take a lot of effort to set up on other systems. This is exactly the kind of complexity nix is designed to accommodate!

Is there a way I can specify "I want hx along with language support for X, Y, and Z" somehow, then rely on nix to set all that up correctly so that hx --health X succeeds all checks for all the languages I want? I think I'd also be happy with a nix install that simply includes all possible LSP providers for as many languages as is feasible.

The nixos install section doesn't mention anything about language support.

I've skimmed over flake.nix but I don't see anything obviously about LSP support for various languages.

I don't think we're intested in providing something like this officially but you could create a Nix library that maps the languages to the language server binaries and wraps the hx binary in a script that set PATH to include the desired language server binaries in the Nix store.

It does seem like it would be pretty easy to cobble together a nixpkgs package which does nothing except depend on the various language servers that helix uses. However it's also been pretty easy to just add them to a home-manager module and then reference that in my system configuration flake.

I haven't done all of them, but so far they've been incredibly easy to find. Their names are either:

• the string shown in hx --health
• nodePackages_latest. + the string shown in hx --health
