Is there a way to do an automatic list-choices after successful completion of directory name?

Is there a way to do an automatic list-choices after successful completion of directory name?

[Nikolai Weibull]

I would like list-choices to be run whenever I have completed a
directory name, e.g.,

  $ cd ~/p<Tab>

completes to

  $ cd ~/projects/

Once completed, I'd like list-choices to be called so that I can see
what directories I have under ~/projects immediately, instead of
having to type another <Tab> right after the first one.

I assume I'll have to write my own completer that I'll bind <Tab> to
that first does a call to _complete somehow, but how do I then tell if
a directory name is what has been completed?

Thanks.

Yes, there is in fact a way to do what you want:

_expand-or-complete-with-list-choices-after-local-directories () {
  zle expand-or-complete
  if [[ $_lastcomp[tags] == ' local-directories ' ]]; then
    zle list-choices
  fi
}
zle -N expand-or-complete-with-list-choices-after-local-directories
_expand-or-complete-with-list-choices-after-local-directories
bindkey "^I" expand-or-complete-with-list-choices-after-local-directories

I'm sure you can come up with a better name for it, but that's what it does...

That technique only works in combination with this (or a similar) zstyle:

    zstyle :completion::complete:cd:: tag-order \
        local-directories path-directories

This fixes that, and also makes it work when completing files:

_expand-or-complete-with-list-choices-after-local-directories () {
  zle expand-or-complete
  if [[ $_lastcomp[tags] == ' '*(directories|files)' ' && $BUFFER[-1]
== '/' ]]; then
    zle list-choices
  fi
}

By the way, why is there a leading and trailing space in $_lastcomp[tags]?

It's a space-separated list, so if it has a leading and trailing space
it can easily be scanned for a specific entry with

	[[ $_lastcomp[tags] = *" entry "* ]]
