completion and .files

completion and .files

[Nikita Borisov]

Whenever I create a complection that uses the -g option of compctl, I
lose the ability to handle .files the way I want, which is simply to say
the same way that zsh handles them normally.

Here's an example - compctl rule for cd.  I start out with the
following:

Attempt #1:
compctl -g '*(-/x)' cd

Now "cd <TAB>" gives me the proper completions for all the directories.
However, "cd .foo<TAB>" gives me an empty completion list, because no
.files match the -g pattern that I give.

Attempt #2:
compctl -g '*(-/x)' -x 'S[.]' -g '.*(-/x)' -- cd 

This fixes the original problem, but "cd ~/.foo<TAB>" fails once again.

Attempt #3:

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

This at least gets all the .directories; however 'cd <TAB>' lists all
my .directories as well.

What I'm basically looking for is to get at all the files that zsh would
have listed had I not used a compctl rule, and filter out any that are
not directories.

How about

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

i.e., try normal globbing first, and if that fails, try again allowing
dot files.

I'd like to implement the ability to do this directly.  I'd like some
way for completion functions to reinvoke the compctl mechanism to
provide it with an array of completions using a normal compctl recipe,
so it could implement more extravagant conditional completions and do
tweaks that a plain compctl can't.  Is this a good idea?

Why don't you use `*(D-/x)' pattern?  The `d' means to include all the
dots except `.' and `..'.  I use:

compctl -g *(D-/) cd

in my .zshrc.
