Regular Expressions Module Project (

This project aims to create a simple and easy to use all-in-one Netbeans plugin for helping developers in all aspects of working with regular expressions in NetBeans, including learning, building, testing, debugging, visualizing, profiling, analysing, organizing, searching and sharing regular expressions.
