I'm getting back into my setup after dualbooting and not touching it for a while. Flakes, home-manager, all that jazz. I was in the middle of messing around with my neovim config, bouncing between nixvim and nixneovim. Can't really remember why I was landing on nixneovim, but I think it had to do with having more 1-to-1 vim options through nix and more available plugins.
Part of this post is just to see what everyone's using, but I also can't copy to the system clipboard for the life of me! No ctrl-shift-v or anything. Oddly enough, ctrl-click-drag will copy a cut-off box of text. In nixneovim there's an option for clipboard, but that's just a string like 'unnamed' or 'unnamedplus', straight from the vim options. Nixvim has the option abstracted in a way that has the register and a provider for the functionality like wl-copy. I don't remember it not working with nixneovim before. That was months ago, though. Hoping someone would have an insight as I've been too deep in the weeds.
Edit: sooooo I just needed xclip in home.packages. I had tried installing it in a nix shell, but maybe that wasn't the right way to test. Doesn't seem to work with wl-clipboard, but I think neovim looks for xclip by default and nixneovim doesn't seem to have a way to give a different provider.
But still, how's everyone doing their neovim shenanigans?
Nixvim is great too. Nixneovim was originally forked from it, apparently. And now that I've been thinking about it, I'm pretty sure the reason I ended up using nixneovim was indeed the way it handles direct vim options, and maybe less need for extraConfig? I've slowly been configuring more as well and didn't want to be confused learning vim config and having to figure out how to convey that in nix.
So that's a thought if you find yourself having the same trouble! It's not just a lot of config, but layers and layers and layers lol. Looking at you, lua in string literals.
