.NET CLI Tab Completion - zsh not evaluating full expression

[gsferreira]

Following the instructions for Tab Completion with Zsh, I realized that the suggestions aren't correct when I'm looking for suggestions inside a command.

Example: dotnet add p suggests pack and publish instead of package.

After digging into it, I realized that the $words variables only capture the last word on the terminal instead of the complete expression.

To fix it, I have updated the snippet to:

# zsh parameter completion for the dotnet CLI

_dotnet_zsh_complete()
{
  local words
  read -Ac words
  local completions=("$(dotnet complete "$words")")

  reply=( "${(ps:\n:)completions}" )
}

compctl -K _dotnet_zsh_complete dotnet

I'm more than happy to open a PR if you agree with the solution.

I'm literally looking at this right now and testing it 😁

@gsferreira Hmmmm that script isn't working for me. it still just displays directories.

[gsferreira]

That is odd.
I have a video here showing it: https://youtu.be/hCsoOVGLCfY

I will get you the versions I'm using later today.

I think its my WSH instance getting dotnet.exe and dotnet confused. I'll load it up in a virtual machine and test. Thanks!

Nope, still not working on an Ubuntu install.

I did find a script that DOES work:

# zsh parameter completion for the dotnet CLI

_dotnet_zsh_complete() 
{
  local completions=("$(dotnet complete "$words")")

  # If the completion list is empty, just continue with filename selection
  if [ -z "$completions" ]
  then
    _arguments '*::arguments: _normal'
    return
  fi

  # This is not a variable assigment, don't remove spaces!
  _values = "${(ps:\n:)completions}"
}
