bug: Neovim plugins are built but not linked into config

[4jamesccraven]

Are you following the right branch?

• [X] My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

• [X] I have searched the existing issues

Issue description

After the latest update to my config, my plugins are built but are no longer sourced into my init.lua as before. Previously the file symlinked to $HOME/.config/nvim/init.lua generated by programs.neovim.extraLuaConfig would contain a line that would source the config generated to init.vim inside /nix/store. This is no longer the case. Additionally, a .drv file was found for the init.vim that should be generated, but on inspecting the intended output with nix derivation show, I found that it was not generated. All of the plugins were built into the store, but for whatever reason the file (which was in the text body of the derivation file) was not built and was not linked into init.lua. I have attached my neovim.nix as well the flake.lock file that shows the exact builds of home-manager and nixpkgs that causes this issue.

I ran into this issue. After some investigation and talking to a friend I believe this is not a home-manager issue, but actually because of a nixpkgs neovim update, I believe this is the offending commit: https://github.com/NixOS/nixpkgs/commit/2f4291af950f6edbcf2d80610c27380e5112f426 but I was not able to confirm it yet.

@rafaelrc7 I tried with that version, but that doesn't seem to be the commit that introduced it. After some testing it seems this commit introduced the issue https://github.com/NixOS/nixpkgs/commit/12dafac23cc3d9998cc5a4ce3485bad1bbba3ae9. I was able to change my flake to point at the parent commit of the problem version to fix my local environment:

 nixpkgs.url = "github:nixos/nixpkgs/11cf80ae321c35132c1aff950f026e9783f06fec";

[SRachamim]

Seems like the config attribute of every neovim.plugins item is ignored.

[euank]

I think this PR fixes this issue: https://github.com/nix-community/home-manager/pull/5976

Testing it locally, it works for me at least!

[svrana]

Seems like the config attribute of every neovim.plugins item is ignored.

All of my type=lua plugin.config attributes seem to make it over to init.lua, but the type=viml ones are lost completely.

[teto]

the change comes indeed fron the nixpkgs change. Behavor of makeNeovimConfig has changed a bit. Can anyone confirm https://github.com/nix-community/home-manager/pull/5976 fixes their issues ? If yes I can merge.

[tmiller]

@teto It worked for me.
