IPython0.11, running under Python 3.2.2
magic_rep and magic_loadpy do not set the next input as expected under Python2
The problem is in core/interactiveshell.py set_next_input(self, s) where:
if isinstance(s, str):
s = s.encode(self.stdin_encoding, 'replace')
works fine under Python2; but in Python3 converts str to bytes
self.rl_next_input = s does not work bytes
Removing the encode makes ipython3 work as expected. However I have not tested it
on a case where the encode matters when using python2. Older versions of ipython do not have this encode statement.
Apparently only these 2 magic functions use set_next_input(), and their failure does not trigger any kind of error message.
Thanks for the report - it's already fixed in master: https://github.com/ipython/ipython/blob/master/IPython/core/interactiveshell.py#L1778
