Separate cdpath elements in path-directories completion

Separate cdpath elements in path-directories completion

[Sebastian Stark]

I have several directories in $cdpath.

In tab completion on cd I have configured "local directory" to show up 
first and then "directory in cdpath". That is almost perfect.

Is it possible to show a separate completion section for each element in 
$cdpath? Looking at the code of _cd I can see that this is happening 
(excerpt):

   tmpcdpath=(${${(@)cdpath:#.}:#$PWD})
   alt=( 'path-directories:directory in cdpath:_path_files -W tmpcdpath -/' )

So I guess it could be done by having my own copy of _cd that changes 
this part of the code.

But perhaps there is a less invasive method I haven't discovered?

You would have to arrange that each directory's name becomes a tag
(the "path-directories:" part in the alt= assignment) and call
"_path_files -W" separately for each directory.  There's no existing
shortcut for this.

Thanks for showing me the right direction. I ended up with the 
following, in case somebody wants that feature too. I can control the 
behaviour by adding

   "zstyle ':completion:*:directories' cdpath-sections true"

to my config.
