@Soupstraw I hope I'm not spamming by asking this again but it was left unclear to me, whether this PR should also rename init.vim to something else to avoid the conflicting configs error?

E5422: Conflicting configs: "/home/kk/.config/nvim/init.lua" "/home/kk/.config/nvim/init.vim"

(I asked this on the first PR as well, but I'm not sure if it was left unnoticed.)

[Soupstraw]

I don't mind renaming, but I'm having a hard time trying to come up with a name. nix.vim sounds like it's configuring nix not neovim.

[Soupstraw]

Or we can get this merged and then open an issue for the renaming. The bug makes neovim unusable for the time being, so the sooner we get this merged the better.

I tested it with my older config and it worked without having to make any changes to the config.

[kiviktnm]

Yeah, that's true. I am quite inexperienced and I don't know what the best practices are so you're probably right. I just thought it might be easier to fix now as well by renaming it to something like config.vim or nvim.vim.

could you rename init.vim to init-home-manager.vim (that's how the lua initrc used to be called) ? it's mandatory to have a different name there my bad. Would be nice to test the whole behaviour. For instance modify this test https://github.com/nix-community/home-manager/blob/master/tests/modules/programs/neovim/plugin-config.nix to check for the presence of the different init files and their content.

fix the format and I merge ty !
