Breaking versions in cz bump #1360

Hello 👋

The conventional commit message format allows for different ways of specifying breaking changes:

3. BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with MAJOR in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type.

However, I can't figure out how to use this in cz bump. It looks like I can use only the type to drive the version number changes. Example pyproject.toml config:

[tool.commitizen]
name = "cz_custom"
tag_format = "$version"
version_scheme = "semver2"
version_provider = "poetry"
update_changelog_on_bump = true

[tool.commitizen.custom]
message_template = "{{change_type}}{% if scope %}({{scope}})){% endif %}{% if breaking %}!{% endif %}: {{description}}{% if body %}\n\n{{body}}{% endif %}"
schema_pattern = "(feat|fix|build|chore|ci|docs|style|refactor|perf|test)(\\([^:]+\\))?(!)?:(\\s.*)"
bump_pattern = "^(feat|fix|style|refactor|perf)(:?\\([^:]+\\))?(!)?"
bump_map = {"!" = "MAJOR", "feat" = "MINOR", "fix" = "PATCH", "style" = "PATCH", "refactor" = "PATCH", "perf" = "PATCH"}

As far as I can tell, bump_map read only the first match. So even if I specify feat!, it doesn't pick it up. The same goes for the BREAKING CHANGE footer.

Is this way of specifying breaking changes even supported or would I have to diverge from the standard and use a breaking kind of type instead?

I read through the entire documentation, searched existing issues and discussions and was not able to find any answers.

Thank you.
