dectools 0.1.0

DecTools provides a library of tools for creating Python decorators. It unifies usage between class decorators, decorators requiring arguments, and simple decorators. It also provides correct names, doc, and function signatures for decorated functions. Typical usage often looks like this:

@make_call_once
def register_callback(function):
      gui.callback_create(function.__name__, function)

@make_call_before
def require_login(function, args, kwargs, page_name):
     while not current_user_id():
        ...

@register
@require_login("Summary of Items")
def view_summary():
    ...

This release has @make_call_(once/before/after/instead). It also has commonly used decorators in this release, including:

• @pre, @post for pre and post condition processing

• @log() for logging function calls

• @invariant, a class decorator, for contract programming
