Regular Expression Debugger

Sample Image - RegExTracer.gif

What is this?

This is a regular expression debugger. You can use it to write regular expressions easier and faster.

Why one more application?

Once I had a need to debug .NET regular expressions. I was not able to find an Rx Toolkit installation, was not able to download Regulator ( was inaccessible), Regex Builder was still in beta state, and crashed on my inputs. So I had the only way to write my own utility. Later it was improved.

nice work!
I tried to recompile the source code, but it doesn't work since the current nabu subversion version is missing some files.

Any clues?
