Re: Zsh autocompletion with no access to a parent directory

Hi all,

I have recently switched from bash to zsh and I am loving it. However,
there are still issues I didn't experience with bash. One of them is
the fact that tabcompletion was not able to cross unreadable parent
directories. With the solution proposed in this thread, this now works
more or less, but not completely... The problem seems to be related to
the use of ~user to access the homedirectory of 'user'.

A minimal example:
  testuser@dirac:~$ ls -ld Desktop/
  drwx--x--x 3 testuser testuser 4096 2010-06-25 09:33 Desktop/

  testuser@dirac:~$ ls -ld Desktop/work/
  drwxr-xr-x 2 testuser testuser 4096 2010-06-25 09:33 Desktop/work/

  testuser@dirac:~$ find Desktop/

If I do (with accept-exact-dirs set to true):

  yves@dirac ~$ ls ~testuser/Desktop/work/<tab><tab>

nothing happens.

However, using the full path name:

  dirac ~$ ls /home/testuser/Desktop/work/<tab><tab>
  dirac ~$ ls /home/testuser/Desktop/work/file
  - files -
  file1  file2  file3  file4

So now it works. What could be going on here, and is there a way to
make the form with ~ work as well? Thanks!

You can try telling completion to accept any directory that it knows exists
without trying to expand the path:

zstyle ':completion:*' accept-exact-dirs true

I'm not sure if this will help in the case you're describing, however,
since it looks like it might not be able to tell if the directory exists.
You'll need zsh 4.3.
