Pyreb is a wxPython GUI to the re python module; it will speed up the development of Python regular expression (similar to PCRE).The GUI is simple and features 3 parts: 1) A text box where the text to be analyzed is displayed 2) A text box where the regular expression to be applied is displayed 3) A tree control where the results are displayed
When one of the two textboxes change the regex is compiled and applied. Errors in the regex are shown in a statusbar.
Pyreb ships with a simple XMLRPC server that can be used to control pyreb from an external application.
Pyreb is somewhat similar to Activestate RX Toolkit (part of Komodo IDE), but is a completely different project.
