Yes, it is. In my previous message I answered Eli. > If that's the case, the "nothing to repeat" error is incorrect: _EXAMPLE_RE > also contains a negative lookahead assertion '(?![ ]*$)' to ensure that the > later '.*$\n?' part never tries to match an empty string. Thank you for explanation. Unlucky the getwidth() method is not smart enough to detect that minimal length of matched string is not 0. We should made either the getwidth() method or the _simple() function (or both) more smart. > A compromise may be to replace > .*$\n? > with > .+$\n? | .*$\n I'm sure similar patterns are used in third-party code. We shouldn't break them, therefore we should fix _simple()/getwidth(). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18647> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
