How ignore PATH with `source` completion

Question

I can't find any 'detailed enough' documentation about zstyle, and I'm surprised that no one faced this problem before:

here is what I get with tab completion:

source l<TAB>
l2ping*                  lefty*                   libwmf-fontmap*          locate*                  lpq.cups

this is certainly/obviously the executable files of my $PATH. However, I would like to use source with a local file, but I can't understand how to change it.

Basically, the command file is completed as I expect, so I'd like to tell zstyle to use the same rules.

I guess that I could adapt :completion:*:killall:* 'ps -u $USER -o cmd h', to do the job, but this would be quite ugly and I'm looking for a zstyle-builtin option.

I thought that I could adapt something like ':completion:*:cd:*' ignore-parents parent pwd to source, but the completion result never changes ...

Answer 1

As of zsh 4.3.10, source is completed by _source which doesn't look up any zstyle. It might be possible to set a style used by _files, but that would be hackish, even by zsh standards.

I suggest that you rewrite the _source function to your liking, it's not very long. Something like:

_my_source () {
  if [[ CURRENT -ge 3 ]]; then
    compset -n 2
    _normal
  elif [[ $service = . ]]; then
      _files -W path
  else
    _files
  fi
}
compdef _my_source source
