Pylex

Fast and simple regex matcher.

Why

I made this fast and usefull script for my language processors class.

How-to

> python pylex.py input.in

input.in

This must be a file containing a list of regexs and a list of test, formatted like this:

^0[0-9]*
[0-9]*0$
%%
0
00
001
1
2
012
210

output

Output is standard console output:

^0[0-9]*             0           [PASS] 
^0[0-9]*             00          [PASS] 
^0[0-9]*             001         [PASS] 
^0[0-9]*             1           [FAIL] 
^0[0-9]*             2           [FAIL]
