Jeremy Thurgood <fir...@gmail.com> added the comment: The weird behaviour is caused by newlines being treated as normal whitespace characters and not actually causing _wrap_chunks() to break the line. This means that it builds "lines" of up to 'width' characters which may contain newlines:
>>> text = '''\ ... aaa aaa aaa ... bbb bbb bbb ... ccc ccc ccc ... ddd ddd ddd''' >>> T = TextWrapper(replace_whitespace=False, width=17) >>> T.wrap(text) ['aaa aaa aaa\nbbb', 'bbb bbb\nccc ccc', 'ccc\nddd ddd ddd'] >>> for line in T.wrap(text): print(line) ... aaa aaa aaa bbb bbb bbb ccc ccc ccc ddd ddd ddd There's no clean way to deal with this inside _wrap_chunks() (as Greg implied), so I think we should just document the existing behaviour and recommend the splitlines() workaround. It might be useful to add a wrap_paragraphs() convenience function that does the split/wrap/join, but I don't think that would add enough value to be worth the change. ---------- nosy: +jerith _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue1859> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
