Display full completion list when inside attribute set

[koffydrop]

Is your feature request related to a problem? Please describe.

In attribute sets, when triggering completion while writing dot-separated names, with the cursor directly after a dot, nixd lists all possible completion values, Eg. in configuration.nix:

programs.zsh./*cursor*/

The same does not happen when nesting them.

programs = {
  zsh = {
    /*cursor*/
  };
};

no completion items appear until something is typed.

programs = {
  zsh = {
    e/*cursor*/ # suggests enable, enableAutosuggestions etc
  };
};

Describe the solution you'd like

Triggering completion inside an attribute set within whitespace should give the same list as when writing the values with dots.

Describe alternatives you've considered

Not nesting attribute sets, which is less convenient for my preference.

Wow, I was under the impression nixd just isn't capable of this kind of completion in general!

I'll be watching this issue hoping to switch back from nil.

this is pretty much a killer feature and what I think would attract much more attention. Oh and also it behaves the same way when using nvim-cmp as op seems to use helix

I've just done some quick development, and the main issue now is:

programs = {
  zsh = {
    /* | */
#      ^ Assuming the cursor is here,
  };
};

the current AST cannot determine whether it is inside a "comment body", which causes nixd to attempt "completion" within comments, and that is undesirable.

[BWagener]

One could argue that if you were to open autocompletion in a comment body in this way, what you're saying is still the expected behavior.

In that case it would be great to have the same behavior for line comments.

Hi, I have the same "issue" with vscode. I was wondering if there was a configuration, to allow that. Any discovery?

I have a fix for this + couple other improvements here: https://github.com/oandrew/nixd/tree/completion-fixes

diff: https://github.com/nix-community/nixd/compare/main...oandrew:nixd:completion-fixes

• show completions when no text under cursor
• increase number of returned completions to 1000
• remove prefix filtering to let vscode do fuzzy matching i.e. typing networking.net will also suggest useNetworkd.

The comments must be addressed first.

I agree it would allow me to use nixd to its full potential
