Installing a neovim IDE layer the Nix-way

Hey @4761 , I do not know about LunarVim or NvChad specifically, but I use AstroNvim which I setup with home-manager:

maxbrunet/dotfiles/blob/c68303bd85f087f7a8e108c938eceab5868ed105/home.nix#L70-L74


      
          nvim = {
            # onChange = "nvim --headless -c 'autocmd User PackerComplete quitall' -c 'PackerSync'";
            onChange = "nvim --headless -c 'if exists(\":LuaCacheClear\") | :LuaCacheClear' +quitall";
            source = sources.astronvim;
          };

And AstroNvim supports loading its config from a location other than ~/.config/nvim, ~/.config/astronvim works out-of-the-box:

github.com

maxbrunet/dotfiles/blob/c68303bd85f087f7a8e108c938eceab5868ed105/home.nix#L56-L60


      
          astronvim = {
            # onChange = "nvim --headless -c 'autocmd User PackerComplete quitall' -c 'PackerSync'";
            onChange = "nvim --headless -c 'if exists(\":LuaCacheClear\") | :LuaCacheClear' +quitall";
            source = ./.config/astronvim;
          };

The onChanges work around an issue with the impatient.nvim: Using `mtime.secs` for hash is incompatible with Nix managed configurations · Issue #42 · lewis6991/impatient.nvim · GitHub. You can ignore if your config does not use it (AstroNvim does).

I manage updates with niv, but nix flake could do too:

niv add AstroNvim/AstroNvim --name astronvim --branch v2.11.8
niv update astronvim --branch <tag>

I do not use any fancy feature from home-manager at the moment (e.g. its neovim modules which would be incompatible beyond installing the package), I only use it to link my dotfiles.

Hope that helps
