Lazy load plugins using lz.n

[arunoruto]

I am following issue #421, which covers possible solutions for lazy-loading plugins in nixvim so that neovim can become a bit snappier. Recently, @GaetanLepage recommended lz.n, which is a sleek solution to the problem. It only does lazy loading, but supposedly, it is doing it well! And if nixvim is used, we do not need the plugin manager aspect of lazy.vim.

I wanted to see if someone is using it so we can share our config and experiences! My current config of lz.n is here. I tried to load nvim-cmp only when insert mode is entered here. Somehow, I am not sure I am doing it right, since vim-startuptime still shows nvim-cmp and other plugins I tried lazy-loading in the resulting profile, but should be only loaded, if a certain command is executed!

I haven't looked for a while, but I think that version of lazy loading doesn't override the runtimepath (like lazy.nvim does).

Instead it just focuses on not calling setup until necessary.

If my above understanding is correct, this means you will see all plugins as loaded, they just won't have been "set up" yet.

I'm not aware of any examples using nixvim and lz.n, but I think a good first step would be to have a nixvim module similar to our lazy.nvim and packer modules.

Thanks for the clarification! I thought loading and setting up a plugin were tied together, but it's a nice thing they can be split! But if I am correct, I have not seen a performance difference (startup time), so I thought I did something wrong...

I guess lz.n would first have to be awalable in nixpkgs under vimPlugins? I have never packaged something for nixpkgs, but maybe this would be a good first try :)
