cmp autocompletion, how to trigger?

[tbaumann]

nvim-cmp seems to have different out of the box experience. The upstream docu seems to suggest that it will just work when enabled.
But with nixvim apparently nothing works out of the box at least. I get no autocomplete box.

I tried these settings, one by one but that doesn't seem to help either

      nvim-cmp.mapping = {
        "<C-Space>" = "cmp.mapping.complete()";
        "<C-d>" = "cmp.mapping.scroll_docs(-4)";
        "<C-e>" = "cmp.mapping.close()";
        "<C-f>" = "cmp.mapping.scroll_docs(4)";
        "<CR>" = "cmp.mapping.confirm({ select = true })";
        "<S-Tab>" = {
          action = "cmp.mapping.select_prev_item()";
          modes = [
            "i"
            "s"
          ];
        };
        "<Tab>" = {
          action = "cmp.mapping.select_next_item()";
          modes = [
            "i"
            "s"
          ];
        };
      };
      nvim-cmp.completion.autocomplete = [ "TextChanged" ];

Hitting Control+Space should have at least make it pop up, but again nothing.

I'm feeling a bit dumb. I have loads of sources configured. And those which make sense for the file-type show up when I type :CmpStatus

My cmp sources

      cmp-calc.enable = true;
      cmp-clippy.enable = true;
      cmp-cmdline.enable = true;
      cmp-fuzzy-buffer.enable = true;
      cmp-fuzzy-path.enable = true;
      cmp-vim-lsp.enable = true;
      cmp-nvim-lsp.enable = true;
      cmp-path.enable = true;
      copilot-cmp.enable = true;
      copilot-lua.enable = true;
      copilot-lua.panel.enabled = false;
      copilot-lua.suggestion.enabled = false;

This is not how you should set up your sources. Instead, you should list them in plugins.nvim-cmp.sources.
Here is an example: https://github.com/GaetanLepage/dotfiles/blob/ac9da05c94268437f6cdc23c4cf0a48a74c11c70/home/modules/tui/neovim/completion.nix#L46-L57

[GaetanLepage]

This is enough: you don't need to manually enable the sources (copilot-lua.enable = true;), this will be done automatically.

[tbaumann]

Thanks, I will play around with that template. I see some nice patterns there.

But wow, a lot more complex than I would have assumed. I would have really expected that cmp sources somehow auto-register :D

[GaetanLepage]

It's kind of the other way around: you tell what sources you want and we (nixvim) automatically enable the relevant plugin.

1. The mapping option you use there - its not longer exists in the docs.
2. The same about sources.

What am I missing here?

It's life with nixvim. I think I will stop using it for now and wait until the dust settled.

It breaks every two weeks. I can't live like that.

It was renamed to be under cmp.settings.mapping and cmp.settings.sources. Has been working fine for me for a long time https://github.com/khaneliman/khanelivim/blob/f77a4bae597efc7c907021bb83b545bba1a61af7/packages/khanelivim/plugins/cmp.nix#L26

If you ever run into breaking changes that don't come with adequate instructions for migrating or have a built-in migration alias please report that as a bug.

While we can't do it in every case, we strive to make any refactoring change as painless as possible. This is just the reality of main being both our dev-branch and the branch that tracks nixos-unstable.

Incidentally, nixos-unstable also often refactor things to add support for new features or allow more "freeform" or "structured config" definitions.

Unfortunately our docs aren't smart enough to pick up on aliases/renames, so links to the old option names will just 404, but building an outdated config should still work and should print warnings stating exactly what has changed.

I still do not see it in the docs. Here is a screenshot:

That's only the nested options that have children.

And now I feel stupid :-)

Thank you for your answer.
