wrapt
A Python module for decorators, wrappers and monkey patching.
Overview
The aim of the wrapt module is to provide a transparent object proxy for Python, which can be used as the basis for the construction of function wrappers and decorator functions.
The wrapt module focuses very much on correctness.
It therefore goes way beyond existing mechanisms such as
functools.wraps() to ensure that decorators preserve
introspectability, signatures, type checking abilities etc. The
decorators that can be constructed using this module will work in far
more scenarios than typical decorators and provide more predictable and
consistent behaviour.
To ensure that the overhead is as minimal as possible, a C extension module is used for performance critical components. An automatic fallback to a pure Python implementation is also provided where a target system does not have a compiler to allow the C extension to be compiled.
