Expose library commands

[andrewdea]

Hello and thank you for this really cool library!

I've tried using this from my python code, but I realized that I needed to expose some of the internal commands.

I made a couple of changes, outlined below. If possible, I would also like to help expand this library so that it can cover other languages besides python.

outline of changes

• create a Rust function code_complexity, that computes the complexity on a string of python code

• expose this function at the level of the python library This way, we can evaluate the complexity on any string of code:

  complexity.main.code_complexity(my_snippet_of_code)

  This is particularly useful in situations where we want to evaluate stand-alone snippets that might not be part of a file-system.

• I thought the Rust function cognitive_complexity was also really useful as a library command, so I exposed it at the python level. Because of Rust's naming rules, it seems it wouldn't allow me to keep that name: it would clash with the module of the same name. So I renamed the function function_complexity file_complexity, which I thought would clarify how it differs from code_complexity. I don't have a strong opinion on the function-names: feel free to propose better ones.

Let me know what you think and if there's any edits you'd like me to make before merging, thanks again!

Hey @andrewdea, thank you for your contribution!

This is a use case I didn't consider, and I find it really useful, so I appreciate these changes.

[rohaquinlop]

Can you please create an issue to relate this PR? And a new issue to discuss the new languages to support them.

[andrewdea]

@rohaquinlop thanks a lot for the comments! I will go through your suggested changes tomorrow. In the meantime I have created issues:

• 45 for this PR

• and #47 for supporting additional languages

[andrewdea]

@rohaquinlop applied the suggested changes, let me know if I'm missing anything 😃

The error at sdist pipeline is related to maturin-action #291, and it seems that can be solved using the ubuntu-22.04 image explicitly as mentioned in the issue

...
    runs-on: ubuntu-22.04
...

@andrewdea We will ignore that error in this PR, there are another pipelines that are failing due to ImportError's

[rohaquinlop]

@andrewdea Can you please modify the CI.yml file and change this line?

...
  sdist:
    runs-on: ubuntu-22.04
    steps:
...

It seems that without that, the unit tests won't run 😢
