1.10.9: Skip empty files in diff

Sometimes empty files are committed.

1.10.8: Skip binary files

Binary files cannot be parsed so we can skip those.

1.10.7: On new files last group is optional

In a git diff when a new file is added only new lines are reported.
So preg_match should consider last group optional.

1.10.6: Clearer error messages

We didn't know what went wrong :worried:

1.10.5: Skip similarity index 100%

We didn't take into account files that only were renamed, this gave a empty diff.
Also if you forget to add a newline at the end of a file, github gives an error line start with a \ so we need to skip those as well.

1.10.4: Just place comment instead of denying PR

When request changes, the pull request stays blocked until bot approves which never happens.
So by just placing it as comment we prevent a pull request getting stuck.

1.10.3: Remove commit hash

Somehow a pull request doesn't give latest commit but merge commit hash instead? By leaving empty review should work.

1.10.2

Testing CodeSniffer #1

1.10.1: Add curl check

Make sure response is succesful.

1.10.0: Let code sniffer do a review

Github API changes forces us to place comments on pull request instead of commits which we did previously.
So converted code sniffer to place a review when it fails and place comments on Pull Request lines when they are inside the diff otherwise we just place it in main comment.
