How can test I regular expressions using multiple RE engines? [closed]

Answer 1

In the standard Python installation there is a "Tools/scripts" directory containing redemo.py.

This creates an interactive Tkinter window in which you can experiment with regexs.

Answer 2

RegexBuddy

Answer 3

Rubular is free, easy to use and looks nice.

Answer 4

I use the excellent and free Rad Software Regular Expression Designer.

If you just want to write a regular expression, have a little help with the syntax and test the RE's matching and replacing then this fairly light-footprint tool is ideal.

Answer 5

I agree on RegExBuddy, but if you want free or when I'm working somewhere and not on my own system RegExr is a great online (Flash) tool that has lots of pre-built regex segments to work with and does real-time pattern matching for your testing.

Answer 6

I'll add to the vote of Reggy for the Mac, gonna try out some of the other ones that Joseph suggested and upvote that post tomorrow when my limit gets reset.
