Actually the name is Simionato ;)
I have just released version 2.0, the new thing is an update_wrapper
function similar to the one
in the standard library, but with the ability to preserve the signature
on demand. For instance
def traced(func):
def wrapper(*args, **kw):
print 'calling %s with args %s, %s' % (func, args, kw)
return func(*args, **kw)
return update_wrapper(wrapper, func, create=False)
works exactly as functools.update_wrapper (i.e. copies__doc__,
__module__,etc. from func to wrapper without
preserving the signature), whereas update_wrapper(wrapper, func,
create=True) creates a new wrapper
with the right signature before copying the attributes.
