• Aspect Weaving Example from My Project

Using aspectlib, Aspect, & weave

You can directly apply the @Aspect decorator to your my_decorator decorator to avoid creating an instance of Aspect. Here's how you can achieve that:

from aspectlib import Aspect, weave

# Your decorator
@Aspect
def my_decorator(func):
    def wrapper(*args, **kwargs):
        print("Decorator: Before function execution")
        result = func(*args, **kwargs)
        print("Decorator: After function execution")
        return result
    return wrapper

# Function from another script
def function_to_weave():
    print("Function: Inside the function")

# Weave the decorator onto the function
weave(my_decorator, function_to_weave)

# Call the woven function
function_to_weave()

In this example, we've applied the @Aspect decorator directly to my_decorator. Then, we use the weave function to apply the woven my_decorator onto the function_to_weave. This approach simplifies the code by avoiding the need to instantiate an Aspect object explicitly.

The walkthrough of the code remains similar, with the main difference being the direct application of @Aspect to the decorator.

Using weave Library

To achieve weaving a decorator aspect onto an existing function using weave, you can follow this example:

import weave

# Your decorator
def my_decorator(func):
    def wrapper(*args, **kwargs):
        print("Decorator: Before function execution")
        result = func(*args, **kwargs)
        print("Decorator: After function execution")
        return result
    return wrapper

# Function from another script
def function_to_weave():
    print("Function: Inside the function")

# Weave the decorator onto the function
weave.function_decorator(function_to_weave, my_decorator)

# Call the woven function
function_to_weave()

In this example, weave.function_decorator from the weave module is used to apply the my_decorator onto the function_to_weave after the fact. The output of the code will include the behavior of the decorator around the function's execution.

Keep in mind that weave is not a standard Python library and might require additional setup or installation depending on your environment. Walkthrough of the code is similar to the previous explanation.
