Hi @YuraBeznos. Thank you for contributing. 🎉
Can you add a unit test for that?

Should conventional-changelog-conventionalcommits use the default revert message and leave the angular preset as is?

[tommywo]

@stevemao https://github.com/angular/angular.js/blob/master/DEVELOPERS.md#revert now doesn't say the message format is autogenerated, but it uses word SHOULD not MUST, so I personally think default message format should be also parsed in angular preset.

@bcoe, @jbottigliero, @byCedric what's your opinion on this? this might affect how commitlint is working after conventional-changelog/commitlint#821 is merged

[bcoe]

should we just make the regex case-insensitive? thoughts @tommywo?

[byCedric]

@tommywo I don't think this is an issue in Commitlint, it's backwards compatible 😄 (at least, I think it is?) We also keep track of some "ignored commits", like reverts (which is case-insensitive already)

closing in favor of #545
