I think this is about to make IPython find the proper docstring of properties
without modifying existing code.

Won't work for properties, as z.prop.__doc__ is in fact z._prop.__doc__, so
future assignment to prop qil lose the docstring.

This function wil do the job, not roughly tested but seems ok, call it at any
moment (startup ?) in the IPython shell.
def make_pinfo() :
"""replace the standard magic_pinfo of itpython
This one will insert __class__. before the last element
if it is a property."""
if not hasattr(__IPYTHON__, 'old_pinfo') :
__IPYTHON__._old_pinfo = __IPYTHON__.magic_pinfo
def new_pinfo(obj) :
"""obj param is the string typed in the interpreter, ie a.b.c
it will be evaluated in magic_pinfo"""
path = obj.split('.')
if len(path) == 1 :
return __IPYTHON__._old_pinfo(obj)
else :
new_eval_string = '.'.join(path[:-1])
# get the last attribute by the mean of the __class__ of its
owner
target = __IPYTHON__.user_ns[path[0]] # user_ns is the
globals of the interpreter
for attr in path[1:-1] :
target=getattr(target, attr)
target = getattr(target.__class__, path[-1], None)
if isinstance(target, property) :
new_eval_string += '.__class__'
return __IPYTHON__._old_pinfo(new_eval_string + '.' +
path[-1])
__IPYTHON__.magic_pinfo = new_pinfo
Hope this help.
regards.
