Jeffrey C. Jacobs <[EMAIL PROTECTED]> added the comment: Ah, I see the problem, if ptr is not incremented, then it will keep matching the first expression, (^z*), so it would have to both 'skip' the 'a' and NOT skip the 'a'. Hmm. You're right, Matthew, this is pretty complicated. Now, for your expression, Matthew, r'(z*)|(^q*)|(\w+)', Perl gives:
"",undef,undef undef,undef,"abc" "",undef,undef Meaning it doesn't even bother matching the ^q* since the ^z* matches first. This seems the logical behaviour and fits with the idea that a Zero-Width match would both only match once and NOT consume any characters. An internal flag would just have to be created to tell the 2 find functions whether the current value of ptr would allow for a "No Zero-Width Match" option on second go-around. _______________________________________ Python tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1647489> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
