I’ve often been annoyed at how creating regular expressions should be a quick process but there’s always some minor problems that seem double (or more) the development time. To solve this problem I made ParserBuilder. It’s a simple program that has one input box where you put the text you want to test your regexp on, one where you put the regexp itself, and an output table that shows the matched groups of the test text and the cool thing is that the parsing is done as you type, so you have instant feedback.
