PR Size Watcher

Checks PR for a total number of additions.

If number of additions is greater than errorSize build will fail, and errorMessage will be added as a comment.

If number of additions is greater than warningSize then warningMessage will be added as a comment.

You can optionally specify excludeTitle regex that will skip this validation if PR title matches the regex.

You can optionally specify excludeLabels: it will skip this validation if PR labels contain one of the labels.

To exclude some files from being calculated use optional excludePaths parameter. It takes a "list" of globs (since GitHub actions don't support passing real yaml lists as input parameters, use syntax from the example below).

To use the action put this into your Workflows file:
