Setting up system clipboard with * and + registers?

[volkswagenfeature]

Curious how you all are enabling system clipboard access. I started by installing xclip, then setting the following in my configs:

programs.nixvim.options.clipboard = {
          name = "Testclip";
          copy = {
            "+" = ["xclip"];
            "*" = ["xclip"];
          };
          paste = {
            "+" = ["xclip"];
            "*" = ["xclip"];
          };
          cache_enabled = true;
}

This is basically just what they suggest in :help clipboard. It doesn't work, so I'm curious how you guys have done it.

Hey, it looks like what you want to set is g:clipboard, and not the clipboard option (options are set with :set in vimscript, e.g. options.numbers = true is the same as :set numbers)

You can set this global setting globals.clipboard instead. I'd also suggest adding xclip by adding it to Nixvim's extraPackages: programs.nixvim.extraPackages = [pkgs.xorg.xclip];.

If you want to be able to copy to the system clipboard without specifying the + register, just set the clipboard option (not global!) to unnamedplus:

programs.nixvim.options.clipboard = ["unnamedplus"];.

Hope this helps! Let me know if you need anything else.

Thank you very much for the clarification! You used options in the docs, but I missed globals all the way at the bottom. Is there a way to see where these are defined? I've recently discovered nix repl. Some other flakes list options in nixosConfigurations.[hostname].config.[package] or other similar locations... But I'm unsure how to see what features have been written for the flake so far: nixosConfigurations.hostname.config.nixvim only contains helpers, which contains a lot of stuff, none of which looks like options I can use in my nix file.

There are module docs over on https://pta2002.github.io/nixvim.

I really need to fix those docs up because the auto generation hasn't been working for a few months, so there are a few plugins missing from there.

Still, it's probably enough for what you need!
