I'm not very familiar with crystal in general.
I tried to refactor the logic and put it into src/run_macros/ but no luck.
Also, all the tests pass, but I believe I should have added one.
Any tips on how to improve it?
Thanks

This is great! Thanks for taking this on. Just a small change to user Crystal's built-in version comparison https://crystal-lang.org/api/1.14.0/Crystal/Macros.html#compare_versions(v1:StringLiteral,v2:StringLiteral):NumberLiteral-instance-method then I think we should be good.

Thanks so much for doing this. Those CI failures are unrelated and I'll fix those later. This looks good! 👍
