示例1: magic_deco
def magic_deco(arg):
call = lambda f, *a, **k: f(*a, **k)
# Find get_ipython() in the caller's namespace
caller = sys._getframe(1)
for ns in ['f_locals', 'f_globals', 'f_builtins']:
get_ipython = getattr(caller, ns).get('get_ipython')
if get_ipython is not None:
break
else:
raise NameError('Decorator can only run in context where '
'`get_ipython` exists')
ip = get_ipython()
if callable(arg):
# "Naked" decorator call (just @foo, no args)
func = arg
name = func.func_name
ip.register_magic_function(func, magic_kind, name)
retval = decorator(call, func)
elif isinstance(arg, basestring):
# Decorator called with arguments (@foo('bar'))
name = arg
def mark(func, *a, **kw):
ip.register_magic_function(func, magic_kind, name)
return decorator(call, func)
retval = mark
else:
raise TypeError("Decorator can only be called with "
"string or function")
return retval示例2: apply_wrapper
def apply_wrapper(wrapper,func):
"""Apply a wrapper to a function for decoration.
This mixes Michele Simionato's decorator tool with nose's make_decorator,
to apply a wrapper in a decorator so that all nose attributes, as well as
function signature and other properties, survive the decoration cleanly.
This will ensure that wrapped functions can still be well introspected via
IPython, for example.
"""
import nose.tools
return decorator(wrapper,nose.tools.make_decorator(func)(wrapper))示例3: mark
def mark(func, *a, **kw):
ip.register_magic_function(func, magic_kind, name)
return decorator(call, func)
