Crate git_conventional[][src]

Expand description

A parser library for the Conventional Commit specification.


use indoc::indoc;

let message = indoc!("
    docs(example)!: add tested usage example

    This example is tested using Rust's doctest capabilities. Having this
    example helps people understand how to use the parser.

    BREAKING CHANGE: Going from nothing to something, meaning anyone doing
    nothing before suddenly has something to do. That sounds like a change
    in your break.

    Co-Authored-By: Lisa Simpson <lisa@simpsons.fam>
    Closes #12

let commit = git_conventional::Commit::parse(message).unwrap();

// You can access all components of the subject.
assert_eq!(commit.type_(), git_conventional::Type::DOCS);
assert_eq!(commit.scope().unwrap(), "example");
assert_eq!(commit.description(), "add tested usage example");

// And the free-form commit body.
assert!(commit.body().unwrap().contains("helps people understand"));

// If a commit is marked with a bang (`!`) OR has a footer with the key
// "BREAKING CHANGE", it is considered a "breaking" commit.

// You can access each footer individually.
assert!(commit.footers()[0].value().contains("That sounds like a change"));

// Footers provide access to their token and value.
assert_eq!(commit.footers()[1].token(), "Co-Authored-By");
assert_eq!(commit.footers()[1].value(), "Lisa Simpson <lisa@simpsons.fam>");

// Two types of separators are supported, regular ": ", and " #":
assert_eq!(commit.footers()[2].separator(), " #");
assert_eq!(commit.footers()[2].value(), "12");
