GUI Regex Tester - Inori - 01-22-2016
I'm trying to familiarize myself with the Tkinter and ttk libraries, so I built a simple regex tester with them. Cool bonus feature of a button that opens the docpage on regex, too.
Only command line option is a --debug flag to, well, enable debugging.
Tip: use chmod +x regextester.py to run the program as an executeable
Source:
Code:
import re
import ttk
from sys import argv
from Tkinter import *
from webbrowser import open as redir
def popup():
if debug: print 'DEBUG:\tOpening regex doc in default browser'
redir('https://docs.python.org/2/library/re.html',new=2,autoraise=True)
