Comment (by jhpalmieri):
I don't understand the `sage0.py` failure. Does the new IPython have a
different default print representation for some objects? Before the
patches here:
{{{
sage: a = 4
sage: a.gcd
<built-in method gcd of sage.rings.integer.Integer object at 0x480e330>
sage: a.gcd?
Type: builtin_function_or_method
Base Class: <type 'builtin_function_or_method'>
String Form: <built-in method gcd of sage.rings.integer.Integer object
at 0x480e330>
Namespace: Interactive
Definition: a.gcd(self, n)
Docstring:
...
}}}
With the patches:
{{{
sage: a = 4
sage: a.gcd
<function gcd>
sage: a.gcd?
Type: builtin_function_or_method
String Form:<built-in method gcd of sage.rings.integer.Integer object at
0x5b7c5a0>
Definition: a.gcd(self, n)
Docstring:
...
}}}
With the old version, the print rep for `a.gcd` is the same as what's
labeled the "String Form" when you do `a.gcd?`. With the new version, the
print rep has changed but the "String Form" has not. I'm also confused by
this behavior (with the patches):
{{{
sage: a = 4
sage: G = a.gcd
sage: G.__repr__()
'<built-in method gcd of sage.rings.integer.Integer object at 0x4b685a0>'
sage: G
<function gcd>
sage: str(G)
'<built-in method gcd of sage.rings.integer.Integer object at 0x4b685a0>'
}}}
Why isn't `G` printed using its `__repr__` method?
I've tried out some other objects (e.g., matrices and elements of the
Steenrod algebra) and my guess is that the print representations for
methods defined in pyx files are getting changed to `<function ...>`,
while those defined in py files haven't changed. Any ideas why? Looking at
`ipython-0.10.2.p1/src/IPython/UserConfig/ipythonrc`, I see the
configuration option `object_info_string_level 0`, which looks relevant,
but we're not using this style of configuration, right?
