The zsh equivalent to Bash's "complete -W" to complete a command using only a list of words

The zsh equivalent to Bash's "complete -W" to complete a command using only a list of words

Hi all,

I am looking for the zsh equivalent of this bash command to complete a
command using a list of words:

            complete -W "$(cat ${__themes_dir}/list-of-themes.txt)" "Theme"

In bash, I can do Theme[space][tab] and it will give me completions only
from the designated words / options / strings.

How can I achieve that using zsh? I want a shell command/built-in for this
- not #compdef / etc.

My Googling/DuckDuckGoing failed me on this.

Regards,

Assuming you have the completion system already loaded, the following is
a fairly standard way of doing it.  The "_wanted" business makes it fit
in with the standard conventions.

pws


_Theme() {
  local expl
  local -a themes
  themes=($(<${__themes_dir}/list-of-themes.txt))
  _wanted tests expl -a themes
}
compdef _Theme Theme

In addition to that I was told on IRC that I can do this:

    compdef "_values $description $val1 $val2 $val3 $val4..." Theme

Where $description is a short description and $val1 $val2 are the values.

Thanks again.

Yes, it does work... you learn something new every day.

} Yes, it does work... you learn something new every day.

And of course to literally satisfy the "I want a shell command/built-in
for this" request, there's always the venerable

    compctl -X $description -k "($val1 $val2 $val3 $val4...)" Theme

That's vulnerable to shell injection.

You need either to change "" to '' or to change «$foo» to «${(q)foo}»,
depending on whether you intend the variables to be interpolated at the
time you run compdef or at the time you invoke the completion.

Cheers,

Daniel
(I realize you might have intended those variables as metasyntax...)
