Commitlint: [FeatureReq] Easy Circle CI setup

[MathiasKandelborg]

It would be great to install a circle-ci package or use an orb to quickly get started.

There's an ENV variable called CIRCLE_COMPARE_URL which can be used to:

1. Find the last successful build
   1.1. If any, get that commit sha
   1.2. If none, fall back to master branch
2. Define range from current commit sha to commit from 1

Although it might be “better” if we could find the default branch at 1.2, this is something we can build too for commitlint.

Thanks for the request. I might be interested too because the place where I work at is considering switching to CircleCI. If I finish some other issues, I'll be available to help get this feature of the ground!

I see that commitlint is using CircleCI now itself. So an easy integration would be appropriate 😉

If you're using pipelines in CircleCI, I believe the following would work:

npx commitlint --from << pipeline.git.base_revision >> --to << pipeline.git.revision >>
