Andrew Barnert added the comment: One last thing, a quick & dirty solution that works today, if you don't mind accessing private internals of stdlib classes, and don't mind giving up the performance of _io for _pyio, and don't need a solution for binary files:
class MyTextIOWrapper(_pyio.TextIOWrapper): def readrecord(self, sep): readnl, self._readnl = self._readnl, sep try: return self.readline() finally: self._readnl = readnl Or, if you prefer: class MyTextIOWrapper(_pyio.TextIOWrapper): def __init__(self, *args, separator, **kwargs): super().__init__(*args, **kwargs) self._readnl = separator For binary files, there's no solution quite as simple; you need to write your own readline method by copying and pasting the one from _pyio.RawIOBase, and the modifications to use an arbitrary separator aren't quite as trivial as they look at first (at least if you want multi-byte separators). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue1152248> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
