completion for dotdirs/symlinks to directories

[Eric.D.Friedman]

Hello,

My .zshrc currently uses the following set for completing "cd" and friends:

# cd/pushd only directories or symbolic links to directories
compctl -g '*(-/)' cd chdir dirs pushd
# skips CVS when changing directories
# compctl -g '*~(*/)#CVS(/)' cd
compctl -g '*(-/)' -g '*~(*/)#CVS(/)' cd chdir dirs pushd

My goal is to be able to skip past CVS directories when completing a path
and to have only directories and symlinks to directories be legal completion
targets.

Currently there are two problems:

(1) I can't get completions for directories that start with a "."  ; and

(2) symlinks to directories do not work.

I'm using zsh-4.0.2 on solaris.

I tried putting "D" in the first completion rule [ as in -g "$(D-/)" ] but
that didn't work out.

Can anyone set me straight?

Thanks,
Eric

Doesn't the second uncommented one replace the first one?

'-', as you noticed.

Thanks -- I see too many reports where that basic info isn't included.
It's not needed in this case, but better to have five words too many
than to miss a vital clue.  :^)

$(...) is command substitution -- the POSIX form of `...`, with
different rules on escaping metacharacters.

How about:
 compctl -g '*~CVS(D-/)' cd chdir dirs pushd

Anything except CVS, and then modifier flags.
Works here (4.0.2/OpenBSD).

I finally got around to actually using this properly for myself, and
very quickly found a flaw.  When excluding, it only matches _exactly_
the path "CVS" in the current directory.  If you have a larger CVS tree,
then CVS entries in that can be matched.

Try:
 compctl -g '*~(*/)#CVS(D-/)' cd chdir dirs pushd 

Which excludes: zero-or-more sequences of "*/", followed by "CVS".

Stunning how quickly the flaw in the original becomes noticeable when
you're migrating to a new CVS server and only have one project, nested
deeply, checked out.  ;^)  Now, three tabs and I'm there.
