No problem. Let me know if I need to do any other changes I have tested on windows 10 wsl. However the regex bug was in cgywin or some other Unix emulator.

I created an small workflow for testing and got testing for OSx and Ubuntu working. I just need to change the alias for python3 in OSx to be python. And some better ui for merge requests. orionnelson#5. Choco only works 25% of the time on GitHub for some reason.

Hi, thanks again for the PR. I took a look and it contains 2 changes:

1. refactoring (moving code into separate functions) & fixes
2. adding tests and github workflow

Can you split them into 2 PRs please? It would be much easier to review. Also, the PR currently contains slide_extractor.py and slide-extractor.py. I believe this is a mistake and slide-extractor.py should be removed.
