[BUG] Statix does not start

Field	Description
Plugin	statix
Nixpkgs	nixos-24.11
Home Manager	release-24.11

• I have read the FAQ and my bug is not listed there.

Description

Provided my understanding is correct, the MRE in the next section should be enough to enable the server.
It seems to be enough as it shows in :LspInfo. However an error message appears in the status line

Client statix quit with exit code 2 and signal 0. Check log for errors: /home/<user>/.local/state/nvim/lsp.log

The relevant part of the log reads:

[ERROR][2025-05-07 21:47:33] .../vim/lsp/rpc.lua:770	"rpc"	"/nix/store/pbwgjxamg2l4pvn278k9i99jqbr8nx75-statix-0.5.8/bin/statix"	"stderr"	"statix 0.5.8\n\nAkshay <nerdy@peppe.rs>\n\nLints and suggestions for the Nix programming language\n\nUSAGE:\n    statix <SUBCOMMAND>\n\nOPTIONS:\n    -h, --help       Print help information\n    -V, --version    Print version information\n\nSUBCOMMANDS:\n    check      Lints and suggestions for the nix programming language\n    dump       Dump a sample config to stdout\n    explain    Print detailed explanation for a lint warning\n    fix        Find and fix issues raised by statix-check\n    help       Print this message or the help of the given subcommand(s)\n    list       List all available lints\n    single     Fix exactly one issue at provided position\n"

It seems like statix is being started without any argument. However, this is doesn’t align with what’s configured in lspconfig-servers.json where it’s defined as:

{
  "cmd": ["statix", "check", "--stdin"],
  "desc": "https://github.com/nerdypepper/statix\n\nlints and suggestions for the nix programming language\n    ",
  "name": "statix"
}

From what I can make out, plugins/lsp/language-servers/default.nix#L198-L199 should likely include the cmd attribute from the json file as well.

Minimal, Reproducible Example (MRE)

programs.nixvim = {
  lsp = {
    enable = true;
    servers.statix.enable = true;
  };
}

It looks like you're confusing the similarly named plugins.lsp and lsp modules.

The former (plugins.lsp) is the current/old module, which combines installing nvim-lspconfig and installing/configuring lsp servers.

The latter (lsp) is the new/experimental module, which does not install nvim-lspconfig and only installs/configures lsp servers.

If you're using the latter, you usually also want plugins.lspconfig.enable.

It seems like statix is being started without any argument. However, this is doesn’t align with what’s configured in lspconfig-servers.json where it’s defined as:

Yes, the new module currently ignores configuration from lspconfig-servers.json. Everything in the generated file comes from nvim-lspconfig, so there's no benefit in nixvim setting it when you can just install plugins.lspconfig.

That said, we did previously maintain a handful of custom cmds for the plugins.lsp module; I'm unsure if we wish to continue doing this in the new lsp module:

nixvim/plugins/lsp/lsp-packages.nix

Hi, thank you for your replies.

I am using nixvim’s nixos-24.11 branch.

For what it’s worth, here’s my work-in-progress config: https://github.com/ithinuel/nix-config/blob/nixvimed/nixvim.nix
