dynamic globbing for cdpath?

dynamic globbing for cdpath?

[Eric D. Friedman]

Is it possible to have an entry in cdpath that contains a shell
globbing pattern that gets reevaulated when I press cd <TAB> ?

Suppose that I have this structure

mkdir -p $HOME/{foo,bar,baz}/branches/

Under those branch directories, there are several distinct subdirs

I'd like to have the branches dirs on my cdpath so that I can cd into
any of the subdirs.

cdpath=($HOME/*/branches)

The issue is that "foo,bar,baz" might grow/shrink to contain new
entries and I'd rather not have to reset cdpath to re-glob.

Is there something I can put into cdpath that will get reevaluated
when I do a cd <TAB>?

You're really asking two almost-unrelated questions here.

The cdpath value might be used by completion, but where it really
matters is when you type "cd somewhere<RETURN>" without completing
first.  No, it's not possible to introduce a glob into that.

What's your objection to resetting cdpath?  You could do it in your
precmd function, for example, so you never have to notice it.

As for the completion-related part of your question, you can use
the fake-files style.  Although the name of the style implies that
the files might not really be there, you can populate the value
with actual files if you want to.  Start with something like this:

zstyle -e ':completion:*' fake-files \
	'reply=($HOME/*/branches); reply=(:"${(@)reply#$HOME/}")' 

Then tweak to suit your preferred behavior.
