This program is a tool for creating and working with regular expressions. You can type your regexps in and see them match the data real time, as well as see a list of all the matches found by the pattern. You can use this to help develop efficient and working regular expressions for your programs without having to spend lots of extra time debugging the expressions from inside a program. Updated Version: Added ability to save expressions and recall them later. Also added the ability to turn off live matching to prevent slowdowns with very large patterns or data.
