Brilliant. These patches are in the recent 3.1.2-zefram version aren't
they? I'll have to compile it.

I think I meant to say "all non-hidden (i.e., starting with ".") 
directories. So it was me being stupid by not reading through what I'd
written before sending it.

Since ./ is only taken into acount once you have typed . and since .. will
always be there, having ./ doesn't really help since you still have to type the
. and the / anyway. So I got rid of this one. Also having '.* ..' as you
suggest is inconvenient when there's only one .xxx subdir since instead of
completing it, zsh asks you whether you want .xxx or ..

So my choice went for:

	compctl -g '*(-/)' + -g '.*(-/)' + -g '..' cd chdir dirs pushd

I should probably add some cdpath handling but I don't use it that much anyway.

I use
compctl -g '*(-/)' + -g '.*(-/)' cd

Which doesn't reproduce the behaviour that you have been describing - it
works fine even when going into the .netscape/ directory.

Another thing:
zsh doesn't complete on ./ and ../, you may have to include those
explicitly with something like

-g '.*(-/) ./ ../'

I cannot reproduce it. compctl -/ cd correctly lists only directories,
with or without . May be, it depends on some options settings; try zsh -f.

I was hoping that these -/ options would fix my problems when I upgraded
to 3.1.2-zefram but that wasn't the case. Using the above compctl for cd
and the 3.1.2-zefram I still get the problems I previously described. If
you can't remember, I shall outline it again:

% compctl -/ cd
% cd
% cd [tab]
 -- Only my directories not beginning with "." are listed which is fine
% cd .[tab]
 -- Only my directories beginning with "." are listed which is fine
% cd .netscape/[tab]
 -- All the *files* and directories in .netscape/ (not starting ".") are
 -- listed! I'd have expected it to complete to "cd .netscape/plugins/"
 -- Also annoying is this behaviour:
% cd ..[tab]
 -- I get a beep! It should complete to "cd ../" as in tcsh.

The new -W option is nice though and seems to work very well. Would be
nice if the -Y compctl option patch was included.

Another problem which I've been having with zsh which wasn't a problem
in 3.0.5 but is in 3.1.2 or 3.1.2-zefram is with a particular bindkey:

Under 3.0.5, I used:
bindkey '^[[161q' up-line-or-search

This meant that if I typed a letter, and then pressed Shift-Up the
history would be searched back for a line starting with what I had typed
and the cursor would be positioned at the end of the line. This worked
in the same way as "history-search-backward" from tcsh and was what I
wanted. Under zsh 3.1.2, I just get a beep when I press Shift-Up.
Instead, I have been using:
bindkey '^[[161q' history-beginning-search-backward
which I don't like as much because it leaves the cursor at the same
position.

I'm sure I'm being stupid, but why on earth would you want
non-directories listed here?  Surely you would only want
directories (named or otherwise) and symbolic links to
directories listed?

Yes.

compctl -/ cd

completes only directories, even beyond the first level.

This is roughly what I use but the annoying thing is that it only works
properly for the first level of directories:

from my home:

cd [tab]
-- all non directories listed - good.
cd .[tab]
-- all hidden directories listed
cd .netscape/[tab]
-- all of the *files* and directories in my .netscape directory listed.

This is one of the main things I miss from tcsh. I'm hoping those recent
patches have sorted this one out but I haven't yet compiled that version
of zsh.

Weird!  When I use that compctl, cd .<TAB> /does/ give me
completions.  Unfortunately cd <TAB> also includes all hidden
files in the completions list.  Why is my behaviour different?

   compctl -g '*(D-/)' cd

is better.  The point of using + is that the non-. filenames are used
if possible, approximating the behaviour of normal filename completion.
Of course, with the recent compctl patches, one should use

compctl -/ cd

What about

   compctl -g '*(-/) .*(-/)' cd

This should work.

also known as

compctl -g '(.*|*)(-/)'

I don't have a comment on the suggestion, just my compctl setting for getting
.<dir>'s to show up:

  # cd/pushd only directories or symbolic links to directories.  If none of those
  # match, resort to shell variables
  compctl -g '*(-/)' + -g '.*(-/)' -v cd pushd rmdir

Completion on cd

[Wessel Dankers]

Hi!

Exploring compctl, I wanted to do completion on cd. So I used the obvious
command:

	compctl -g '*(-/)' cd

which gives me what I want... almost. If I enter:

	cd .<TAB>

I get no completions. OK, I thought, let's try a different approach.

	cdcomp() { setopt local_options null_glob; reply=($1*$2(-/)) }
	compctl -S / -q -K cdcomp cd

Almost right, but still not quite. If I enter:

	cd ^D

(^D does list-choices) I don't get slashes/at-signs behind the names
indicating whether it's a directory or a link. 

The problem is obviously that -g should be passed the current prefix and
suffix. Letting the completion mechanism select the possible entries just
isn't enough. Or would it be an idea to integrate globbing and completion
altogether, so that a * does not expand to all possible files/directories
but to all possible selections in that position. In general, these would
be files, but in other places hostnames, etc. This would be an easy way to
get, say, all hostnames, or perhaps all manpages starting with zsh...

Just an idea.
