This is a fantastic little Python GUI using Tkinter, for testing your regular expressions in Python. You first paste or write in some text, then you doodle some regular expressions to see the outcome. What I do miss is exporting of actual code. Usually when I write my regular expression I fire up the interactive shell from which I can copy code when I'm happy with it. Like this:
>>> import re >>> e=re.compile(r'\?q=(.*?)&', re.I) >>> print e.findall("http://www.google.com.br/search?q=paper+plane&hl=pt-BR") ['paper+plane']
From silly code like that I can actually copy and paste the actual syntax. Ah well, I still like this Recon thing.
