Aspect-Oriented Programming toolkit.
Project description
aspectlib is an aspect-oriented programming, monkey-patch and decorators library. It is useful when changing behavior in existing code is desired.
Documentation
Docs are hosted at readthedocs.org: python-aspectlib docs.
Implementation status
Weaving functions, methods, instances and classes is completed.
Pending:
Whole-module weaving
Concerns (see docs/todo.rst)
If aspectlib.weave doesn’t work for your scenario please report a bug !
Requirements
- OS:
Any
- Runtime:
Python 2.6, 2.7, 3.3, 3.4 or PyPy
Python 3.2, 3.1 and 3.0 are NOT supported (some objects are too crippled).
Changelog
Version 0.8.1
Use simpler import for the py3support.
Version 0.8.0
Change aspectlib.debug.log to use aspectlib.Aspect and work as expected with coroutines or generators.
Fixed aspectlib.debug.log to work on Python 3.4.
Remove the undocumented aspectlib.Yield advice. It was only usable when decorating generators.
Version 0.7.0
Add support for decorating generators and coroutines in aspectlib.Aspect.
Made aspectlib raise better exceptions.
Version 0.6.1
Fix checks inside aspectlib.debug.log that would inadvertently call __bool__/__nonzero.
Version 0.6.0
Don’t include __getattribute__ in ALL_METHODS - it’s too dangerous dangerous dangerous dangerous dangerous dangerous … ;)
Do a more reliable check for old-style classes in debug.log
When weaving a class don’t weave attributes that are callable but are not actually routines (functions, methods etc)
Version 0.5.0
Changed aspectlib.debug.log:
Renamed arguments to call_args.
Renamed arguments_repr to call_args_repr.
Added call option.
Fixed issue with logging from old-style methods (object name was a generic “instance”).
Fixed issues with weaving some types of builtin methods.
Allow to apply multiple aspects at the same time.
Validate string targets before weaving. aspectlib.weave('mod.invalid name', aspect) now gives a clear error (invalid name is not a valid identifier)
Various documentation improvements and examples.
Version 0.4.1
Remove junk from 0.4.0’s source distribution.
Version 0.4.0
Changed aspectlib.weave:
Replaced only_methods, skip_methods, skip_magicmethods options with methods.
Renamed on_init option to lazy.
Added aliases option.
Replaced skip_subclasses option with subclasses.
Fixed weaving methods from a string target.
