Description

After migrating my home-manager based nixvim configuration to a seperate flake, my filetype configuration is broken. As far as I can tell, the filetype setting files are not added to the runtimepath, despite the option description saying so.

For the example down below, I can see the created file at /nix/store/<hash>-vim-pack-dir/pack/myNeovimPackages/start/nvim-config/after/ftplugin/haskell.lua

I am using and building nixvim on Darwin.

Minimal, Reproducible Example (MRE)

Inside a standalone nixvim configuration:

extraFiles = {
    "after/ftplugin/haskell.lua".text = ''
      vim.bo.tabstop = 2
      vim.bo.shiftwidth = 2
      vim.bo.expandtab = true 
    '';
 };

is this behavior intended?

[MattSturgeon]

is this behavior intended?

No, extraFiles should be on the runtimepath.

However IIRC (neo)vim is kinda weird about how you can source files from the rtp? IIRC they have to be under certain plugin directory names?

If you run :set rtp? in vim, it'll print the full rtp. It may be pretty long.
I'm interested in whether /nix/store/<hash>-vim-pack-dir is in the rtp list... If it is, then I think everything is working fine.

For me I have

• /nix/store/kc0qh09d08krl1m15bhjbs63hiqbikxr-vim-pack-dir
• /nix/store/kc0qh09d08krl1m15bhjbs63hiqbikxr-vim-pack-dir/pack/*/start/*
