Background
=====================================

Ok...the good news is that I wrote a AnyData::FORMAT module called Directory that allows me (for the time being) to access directories and return various file information (path, basename, ext, size, etc) like database results. This work great with the DBI in listing files.

What I'm trying to do
=====================================

Here is my problem. Now that I have successfully returned all the files from a specified folder, I want to do a regex to filter the returned results. SQL::Statement supports a feature called RLIKE that allows for Perl-based regex therefore I'm going that way. Only problem is that I don't know how to create the expression; go figure.

Example
=====================================

I have a list of files like so:

bluff_park_000712-001.jpg
~bluff_park_000712-001.jpg
~bluff_park_000712-001.jpg.caption

This constitutes one complete set of which I have thousands. The first is the full-size image, the second is a thumbnail, and the third is a text file with a caption for the thumbnail.

When I display to my users the flying site location names, "Bluff Park" is what they will see. I need a way to take "Bluff Park", lower case it, replace <space> with <underscore> and add a <tilde> to the front of it...all in the regex (if possible). That is just setup. Then I need to take that and run it against all the entries to have it return only those that begin with that:

Evaluate all filenames for those starting with ~bluff_park

This should return:

~bluff_park_000712-001.jpg
~bluff_park_000712-001.jpg.caption

As for the extension portion, I've got that part figured out.

TIA
