standard-commit

Conventional commit parsing, validation, and formatting.

Implements the Conventional Commits specification as a pure library — no I/O, no git operations, no terminal output.

Entry points

• parse — parse a commit message into a ConventionalCommit
• lint — validate a message against a LintConfig
• format — render a ConventionalCommit back to a string

Example

use standard_commit::{parse, format, lint, LintConfig};

let commit = parse("feat(auth): add OAuth2 PKCE flow").unwrap();
assert_eq!(commit.r#type, "feat");
assert_eq!(commit.scope.as_deref(), Some("auth"));

// Round-trip: format back to string
assert_eq!(format(&commit), "feat(auth): add OAuth2 PKCE flow");

// Lint with default rules
let errors = lint("feat: add login", &LintConfig::default());
assert!(errors.is_empty());

Part of git-std

This crate is one of four libraries powering git-std, a single binary for conventional commits, versioning, changelog, and git hooks.
