Question. Autocomplete paths starting with %.

[d...@ucore.info]

Hi,

I'm not subscribed to this list so please make sure to CC me if you
want me to receive the reply.

I'd like to hack some solution based on:
http://www.huyng.com/bashmarks-directory-bookmarks-for-the-shell/

but to be able to use saved bookmarks in other commands (explanation below).

So if I have a bookmark:
webdir=/home/dpc/www

I could do:

$ cp xfile %webd

and that autocomplete to:

$ cp xffile /home/dpc/www

The % signed would be similar to what bash already does for @, ~ and
$. Only this one would be for bookmarks.

I can script in Bash quite well, but I've never did anything that
fancy with completion and I don't know how to plug my function to
handle this. I understand that I should register something (function
named like _bookmarkcomp) to handle filename completion for things
beginning with %.

If you help me with this one I promise to post my solution for benefit
of other bash users.

Regards,
Dawid

Thanks.

However this only registers for foo. What if I wanted to handle % for
everything or even better ... only at places that expect the path? Any
way to force bash to do that?
