How do I get the cyclomatic complexity of a file before change?

[ks3057]

Hi! I can see the Modification object returns the cyclomatic complexity of a file changed in a commit. Is there a way to check what it was previously? Basically, I'd like to get a diff of the cyclomatic complexity for comparison.

@ks3057 perhaps you can use this method

pydriller/pydriller/domain/commit.py

Line 436 in 2ad53b0

def _calculate_metrics(self, include_before=False):

with a flag include_before=True?

Hi @ks3057, sorry I haven't replied sooner, I missed this discussion.

Yes you are right, the complexity at file level is only calculated after the change, while the complexity at method level can be calculated before and after. I think we can add the complexity at file level before. What do you think, can you work on a PR?
