git-cliff is a command-line tool (written in Rust) that provides a highly customizable way to generate changelogs from git history. It supports using custom regular expressions to alter changelogs which are mostly based on conventional commits. With a single configuration file, a wide variety of formats can be applied for a changelog, thanks to the Jinja2/Django-inspired template engine. More information and examples can be found in the GitHub repository.

What's new?

The full changelog can be found here.

Bump version 🆙

git-cliff can calculate the next version based on conventional commits and bump the version for the unreleased changes for you!

--bump: Bumps the version for unreleased changes

For example, if you have 1.0.0 and committed "feat: xyz", git-cliff --bump --unreleased will create a changelog for 1.1.0.

How it works is that for a semantic versioning such as <MAJOR>.<MINOR>.<PATCH>:

• "fix:" -> increments PATCH
• "feat:" -> increments MINOR
• "scope!" (breaking changes) -> increments MAJOR

Better grouping 👥

Now you can group commits by their attributes, i.e. name of the author, email, etc.

For example, to group the commits that belong to Dependabot under "Dependency Updates" in the changelog:

[git]
# regex for parsing and grouping commits
commit_parsers = [
  { field = "author.name", pattern = "dependabot\\[bot\\]", group = "Dependency Updates"},
]

This will result in:

### Dependency Updates

- _(deps)_ Bump regex from 1.9.6 to 1.10.0
- _(deps)_ Bump toml from 0.8.1 to 0.8.2
- _(deps)_ Bump regex from 1.9.5 to 1.9.6

The supported commit attributes (fields) are:

• id
• message
• body
• author.name
• author.email
• committer.email
• committer.name

Glob -> Regex 🧶

[git].tag_pattern was only supporting glob patterns for matching (mostly due to the underlying support of such glob by git2), now it directly supports regular expressions:

[git]
- # glob pattern for matching git tags
+ # regex for matching git tags
- tag_pattern = "v[0-9]*"
+ tag_pattern = "v[0-9].*"

Auto-fix typos ✍️

Here is a git-cliff configuration for automatically fixing the typos in the commit messages before they appear in the changelog:

# regex for preprocessing the commit messages
commit_preprocessors = [
  # Check spelling of the commit with https://github.com/crate-ci/typos
  # If the spelling is incorrect, it will be automatically fixed.
  { pattern = '.*', replace_command = 'typos --write-changes -' },
]

This configuration was added to the git-cliff's repository config (not default) in #316 and runs typos for each commit. There is also a good first issue to improve this.

Emacs support 😈

RustLab 2023 📢

I'm happy to announce that I will be talking about git-cliff at RustLab 2023! 🎉

https://rustlab.it/talks/turning-git-commits-into-changelog-with-git-cliff

In this talk, I will be sharing the story behind git-cliff, implementation details with certain design choices, and most importantly how to work with Git objects using Rust. Also, I will be sharing examples of how to use git-cliff and integrate it with your project.

Additionally, I will be giving tips on creating a successful command-line tool in Rust and publishing it as open source.

• Dates: November 19th -> November 21th
• Location: Florence, Italy
• Tickets: https://rustlab.it/tickets
