A Python module for decorators, wrappers and monkey patching.
|
||
|
|
|
||
|
|
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.
