feat: add release-drafter.yml

[shenxianpeng]

Here, we used the default configuration in git cpp-linter/.github/release-drafter.yml. However, it can be overwritten if needed.

I don't fully understand how the config works. In order to use categories, I think we need to create a few labels (for each cpp-linter repo). Then add the right label to certain PRs so release-drafter will categorize them accordingly.

Maybe I'm misunderstanding this entirely.

According to the release-drafter docs, the resolved version defaults to a patch bump. To make it bump a minor or major version, we need to add new labels named "major" and "minor".

Then apply the label "minor" to any PR that would imply a minor version bump (as I did for the cpp-linter/cpp-linter#51 PR). The "major" label should only be used for PRs that implement breaking changes.

We need to add major, minor, and patch labels for all repos for the auto-suggest version feature. we can maintain all labels here https://github.com/organizations/cpp-linter/settings/repository-defaults

The above link to the setting is only applies to new repo. for the existing repo we need to add related labels manually 😢

[shenxianpeng]

I think it's ready for review. let's see how it works 😃

If this repo works as we expect, I will make the same changes to other repos later.

It worked! A release for v2.7.7 was just drafted.

[shenxianpeng]

Yeah, it seems will draft for each merge. Anyway, we can decide whether we need to publish it or not.

I think this also means no more quick commits to default branches. Seems release-drafter will only work for PR merges?

[shenxianpeng]

I think this also means no more quick commits to default branches.

Yes. Right now it works for any new changes made on the main branch

[2bndy5]

I mean only for PRs, not for a direct commit to the main branch. right?

[shenxianpeng]

Oh yes, I think so.
