Python allows programmers to pass additional arguments to functions via comments.
Now armed with this knowledge head out and spread it to all code bases.
Feel free to use the code I wrote in your projects.
# First we have to import comment_arguments from arglib
# Sadly arglib is not yet a standard library.
from arglib import comment_arguments
def add(*args, **kwargs):
c_args, c_kwargs = comment_arguments()
return sum([int(i) for i in args + c_args])
# Go ahead and change the comments.
# See how they are used as arguments.
result = add() # 1, 2
print(result)
# comment arguments can be combined with normal function arguments
result = add(1, 2) # 3, 4
print(result)
Choosing lib as the name for my module was a bit devious.
I did it because I thought if I am creating something cursed why not go all the way?
Regarding misinformation:
I thought simply posting this in programmer humor was enough.
Anyways, the techniques shown here are not yet regarded best practice.
Decide carefully if you want to apply the shown concepts in your own code bases.
The add() function (that is available in the source code) basically uses some built in debugging tools to find out where in the code the function is called, and then parses the comment from the file and uses it for adding stuff.
I’ve never tried (becuse why would you…) but something similar can probably be built in any interpreted language
This specific use case? To make a meme, mainly ¯\(ツ)/¯
As for the components:
Parsing comments have been used for stuff like type hints / formatting / linting, tho generally not at run time (afaik).
The tooling for finding out where something is called from can be used to give a better understanding of where things go wrong when an exception happens or similar, to add to logs.
I would say that in general you don’t need either functionality except for certain edge-usecases
We actually use method comments for user documentation as well. Only on specific business methods, but it's nice to have a good comment for the dev and a tooltip for the user at the same time.
