Support labeling based on size of change

[dfandrich]

I would like to add a label in certain cases based on files changed, but only if the commit changes fewer than N files in total. Anything more than N and the change is likely a global refactor and adding the specific label won't add any value.

hi @dfandrich, thank you for the report, we will take a look at it.

Mentioned in vmware-tanzu/vm-operator#50 (review) (this was not added automatically for some reason)

@panticmilos and @MaksimZhukov I'm working on a PR for this in my personal fork right now but I currently have a breaking change with the way the config is written. I basically put the existing config under a top level section name labels and added a new optional section called sizes.

Obviously there are other options for handling this:

• a separate config file in the .github dir
• an additional optional input to the action
• some code to check if there is a labels top level item in the config and if not, fall back to the previous parsing

Do you guys have a preference?

So I just noticed there is a v5 WIP with breaking changes in it so maybe I'll just work off of that branch

Any chance we can get some traction on this @MaksimZhukov ? 🙏

I've been using this Labeler Action alongside https://github.com/pascalgn/size-label-action with good success.

It'd be nice to just use one Action instead of two, since there's already a PR open in this repo for the same functionality...

I just tacked https://github.com/pascalgn/size-label-action as the next step in the labeler workflow. It's instant so there's basically no cost to having two steps in the labeler job.
