Xapian discuss - Feb 2009 - Omega Script

I really like Omega script but I've run into a problem and am not sure 
what is the best way to get around it.

When I return the names of files from a search result I use $field{url} 
which returns \\server\docs\foo.doc

What should I do if I only want foo.doc to be displayed?

I was wondering where in the documentation I should look to find what 
fields are available to use with $field{}

And how hard would it be to create new script index commands like 
$filename and $path.  If extending omega script is easy/"a good idea" 
I'd be happy
to write some documentation once I learn how.

Thanks,

Frank

If you want to do it with the current set of commands, using $transform
might be a good approach. Of course, that might be more difficult if you
have to cater for lots of different path conventions.

Extending OmegaScript is not that hard (add a few lines to query.cc),
but I am not sure that with the current implementation it is a good idea
to try to add a whole bunch of "library functions" to it. Personally,
my
approach to this has been to try to use custom indexing and make do with
(as far as possible) stock omega, but that may be a matter of taste, too.

Kind regards
