A regex tool -- A Python GUI for creating, testing and debugging regular expressions for the Python programming language. Kodos utilizes the pyqt library for it's interface. Screenshots available on project homepage.
This one is far more user & developer friendly then visual-regexp and redet. Great job. The best open source for regex development.
Over the months, Kodos is the only tools that comes to my mind when working on regexp. I saved me huge amounts of time
Use it all the time.
