Hi!
I am working with the gap3 devs on introspection with ?? I gather
that one approach is to implement _sage_src_ to return a string
representation of the code.
Any idea why the first example below gives a "source file open
failed", whereas the second works? Where is the code in charge of
this?
sage: class blah(SageObject):
....: def _sage_src_(self):
....: return 'f\n r\n r\n'
....:
sage: x = blah()
sage: x??
Type: blah
Base Class: <class '__main__.blah'>
String Form: <class '__main__.blah'>
Namespace: Interactive
File:
/opt/sage/local/lib/python2.6/site-packages/IPython/FakeModule.py
Docstring [source file open failed]:
x.__init__(...) initializes x; see x.__class__.__doc__ for signature
sage: class blah(SageObject):
....: def _sage_src_(self):
....: return 'coucou\nr\n'
....:
sage: x = blah()
sage: x??
Type: blah
Base Class: <class '__main__.blah'>
String Form: <class '__main__.blah'>
Namespace: Interactive
File:
/opt/sage/local/lib/python2.6/site-packages/IPython/FakeModule.py
Source:
coucou
r
Thanks!
Nicolas
