Writing nix code

Help
1

Writing Nix code is a hassle, with all these available options and stuff, I use neovim as my code editor and I would like to know if there’s any LSP not just for formatting or for the Nix language basics but also for suggesting available options and stuff

nixd provides support for options, eval errors, etc. This is probably what you are looking for:

Both nixd and nil support completion for NixOS options (nixd also supports Home Manager!), but also error checks, lints, code refactor commands and all the stuff regular programming language tooling have whereas devenv lsp seems to be only intended to provide completions for Devenv’s own module system.

nil doesn’t work for me so that’s why I was looking for some alternatives, and this is what I had to settle with for now:

local lspconfig = require("lspconfig")
lspconfig.nixd.setup {}
-- other stuff
    if server == "nil_ls" then
        lspconfig.nil_ls.setup({
            settings = {
                ['nil'] = {
                    formatting = {
                        command = { "nixfmt" }, -- nixfmt available on nixpkgs and this is what I use for formatting
                    },
                },
            },
        })
