JSSupported

JavaScript / ECMAScript

Browser-native RegExp. Default if you don't pick.

PYSupported

Python (re)

CPython stdlib `re`. Unicode-aware `\w` and `\d` by default.

GOSupported

Go (RE2)

Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic
^(feat|fix|docs|style|refactor|perf|test|build|ci|chore|revert)(\([a-z0-9\-]+\))?(!)?:\s.+   (flags: i)

Raw source: ^(feat|fix|docs|style|refactor|perf|test|build|ci|chore|revert)(\([a-z0-9\-]+\))?(!)?:\s.+

How it works

The first group captures the commit type from the allowed list. (\([a-z0-9\-]+\))? optionally captures a scope in parentheses. (!)? captures a breaking change marker. :\s requires a colon and space before the description. The i flag makes types case-insensitive.
