Suppose I have a function in module X that calls eval e.g,
X.py
_______
Def foo(bar):
Eval(bar)
_______
Now eval will be called using the default eval(bar,globals(),locals())
and globals will pull in anything in module X.
Now I have module Y that calls bar like so
Y.py
________
from x import *
def biz():
print "Im a silly example!"
Foo("biz()")
_______
Python will complain that it cannot find biz because it's not the X
module.
My question - is there any way to a) get a listing of active namespaes
search ALL active namespaces for a particular variable b) get the
namespace of the caller withing passing it in (here, Y) c) do anything
else to get biz without passing foo("biz()",locals(),globals()) or
hacking biz into the __builtin__ namespace(don't know if it's even
possible, but it defeats the purpose of what I'm trying to do) ? I
realize this is here for a reason, but I'm working on something that's
kind of a hack already
Thanks

More gratuitous context. Long story I'm trying to write a hack for a
concise way of adding arbitrary methods to objects for JPA/JQuery like
chaning eg.
def foo(self):
class wrap:
def __init__(self, obj, globalz=globals(),localz= locals()):
self.obj = obj
self.localz = localz;
self.globalz = globalz;
def __callback__(self, *args, **kw):
newargs = [self.obj];
newargs.extend(args);
print locals
ret = eval(self.name, self.globalz, self.localz)
(*newargs,**kw);
return wrap(ret);
def __getattr__(self,name):
if hasattr(self.obj,name):
return getattr(self.obj,name);
self.name = name;
return self.__callback__;
