very naïve solution:
def mixin(obj):
def someFunc(self, ...)
# code here
def someOtherFunc(self, ...)
# code here
cls = obj.__class__
cls.someFunc = someFunc
cls.someOtherFunc = someOtherFunc
Just a bit less nïave solution:
def mixin(func):
func._mixin = True
return func
def mixable(func):
return getattr(attr, '_mixin', False):
class Mixin(object):
@mixin
def someFunc(self, ...):
# code here
@mixin
def someOtherFunc(self, ...)
# code here
def mix(cls, mixincls):
for name in dir(mixincls):
attr = getattr(mixincls, name)
if callable(attr) and mixable(attr):
setattr(cls, name, attr)
Of course, one can do much better...
