Re: [Bug-readline] directory_completion_hook interacts with tilde expansion

[Stefan H. Holek · Jarn]

Not so fast!

I have a custom dequoting function that performs backslash-dequoting,  
and I *must* install it as a directory_completion_hook as well, or I'd  
be unable to complete paths like 'funny\ dir/foo'.

The culprit appears to be this: While the filename_dequoting_function  
results are assigned to 'user_dirname', opendir is called with  
'dirname', effectively receiving a still quoted directory name.

The rl_filename_completion_function again:

      if (rl_directory_completion_hook &&  
(*rl_directory_completion_hook) (&dirname))
        {
          free (users_dirname);
          users_dirname = savestring (dirname);
        }
      else if (rl_completion_found_quote &&  
rl_filename_dequoting_function)
        {
          temp = (*rl_filename_dequoting_function) (users_dirname,  
rl_completion_quote_character);
          free (users_dirname);
          users_dirname = temp;
        }
      directory = opendir (dirname); /* <-- STILL QUOTED! */

I fear you are going to tell me it's by design again, but I fail to  
see how this is useful behavior - yet. ;-)

Thanks,
Stefan
