I just had the occasion to write a regular expression and test it out, so I thought I would use the Rad Rails Reg Exp view that has been sitting on the bottom of my screen since I started using Rad Rails.
A client is capturing images from a camera plugged into a TV card, using the might xawtv configured to point to the public area of the application.
They need to be identified by their filename, moved elsewhere and logged in the database for future reference.
So it was dead easy to test out a quick regular expression to capture the filename:

Very useful: the little running man validates and highlights the text matched by the regular expression, while the green arrows arrows step you through it (forwards and backwards); and the little red square resets the sequence.
