convenience facilities related to Python functions
Project description
funcname(func)
Returns a string to name func. I use this instead of func.__name__ because several things do not have a .__name__. It tries to use .__name__, but falls back to ..__str__().
@derived_property
Decorator for property functions which must be recomputed if another property is updated.
@derived_from(property_name)
Convenience wrapper of derived_property which names the parent property.
@returns_type(func, basetype)
Basis for decorators to do type checking of function return values. Example:
def returns_bool(func): ''' Decorator for functions which should return Booleans. ''' return returns_type(func, bool) @returns_bool def f(x): return x == 1
This has been used for debugging functions called far from their definitions.
