Command Line Arguments

git-cliff [FLAGS] [OPTIONS] [RANGE]

Flags:

-v, --verbose       Increases the logging verbosity
-i, --init          Writes the default configuration file to cliff.toml
-l, --latest        Processes the commits starting from the latest tag
-u, --unreleased    Processes the commits that do not belong to a tag
-h, --help          Prints help information
-V, --version       Prints version information

Options:

-c, --config <PATH>        Sets the configuration file [env: CONFIG=]  [default: cliff.toml]
-w, --workdir <PATH>       Sets the working directory [env: WORKDIR=]
-r, --repository <PATH>    Sets the git repository [env: REPOSITORY=]
    --commit-path <PATH>   Sets the directory to parse commits from [env: COMMIT_PATH=]
-p, --prepend <PATH>       Prepends entries to the given changelog file [env: PREPEND=]
-o, --output <PATH>        Writes output to the given file [env: OUTPUT=]
-t, --tag <TAG>            Sets the tag for the latest version [env: TAG=]
-b, --body <TEMPLATE>      Sets the template for the changelog body [env: TEMPLATE=]
-s, --strip <PART>         Strips the given parts from the changelog [possible values: header, footer, all]
    --sort <sort>          Sets sorting of the commits inside sections [default: oldest] [possible values: oldest, newest]

Args:

<RANGE>    Sets the commit range to process

Examples

The default configuration file (cliff.toml) can be generated using the --init flag:

# create cliff.toml
git cliff --init

Then simply create a changelog at your projects git root directory:

# same as running `git-cliff --config cliff.toml --repository .`
# same as running `git-cliff --workdir .`
git cliff

Set a tag for the "unreleased" changes:

git cliff --tag 1.0.0

Generate a changelog for a certain part of git history:

# only takes the latest tag into account
# (requires at least 2 tags)
git cliff --latest

# generate changelog for unreleased commits
git cliff --unreleased
git cliff --unreleased --tag 1.0.0

# generate changelog for a specific commit range
git cliff 4c7b043..a440c6e
git cliff 4c7b043..HEAD
git cliff HEAD~2..

Generate a changelog scoped to a specific directory (useful for monorepos):

git cliff --commit-path project1/

Sort the commits inside sections:

# The oldest commit will be on top.
# (default)
git cliff --sort oldest

# The newest commit will be on top.
git cliff --sort newest

Save the changelog file to the specified file:

git cliff --output CHANGELOG.md

Prepend new changes to an existing changelog file:

# 1- changelog header is removed from CHANGELOG.md
# 2- new entries are prepended to CHANGELOG.md without footer part
git cliff --unreleased --tag 1.0.0 --prepend CHANGELOG.md

Set/remove the changelog parts:

git cliff --body $template --strip footer

Also, see the release script of this project which sets the changelog as a message of an annotated tag.

Docker

The easiest way of running git-cliff (in the git root directory with configuration file present) is to use the available tags from Docker Hub:

docker run -t -v "$(pwd)/.git":/app/ orhunp/git-cliff:latest

Or you can use the image from the GitHub Package Registry:

docker run -t -v "$(pwd)/.git":/app/ docker.pkg.github.com/orhun/git-cliff/git-cliff:latest

Also, you can build the image yourself using docker build -t git-cliff . command.

GitHub Action

It is possible to generate changelogs using GitHub Actions via git-cliff-action.

- name: Generate a changelog
  uses: orhun/git-cliff-action@v1
  with:
    config: cliff.toml
    args: --verbose
  env:
    OUTPUT: CHANGELOG.md

See the repository for other examples.

Also, see the continuous deployment workflow of this project which sets the release notes for GitHub releases using this action.

Configuration File

git-cliff configuration file supports TOML (preferred) and YAML formats.

The configuration file is read from $HOME/git-cliff/cliff.toml if the file exists. This location depends on the platform, for example:

on Linux: /home/<user>/.config/git-cliff/cliff.toml
on Windows: C:\Users\<user>\AppData\Roaming\git-cliff\cliff.toml
on macOS: /Users/<user>/Library/Application Support/git-cliff/cliff.toml

See config/cliff.toml for the default configuration values.

changelog

This section contains the configuration options for changelog generation.

[changelog]
header = "Changelog"
body = """
{% for group, commits in commits | group_by(attribute="group") %}
    ### {{ group | upper_first }}
    {% for commit in commits %}
        - {{ commit.message | upper_first }}
    {% endfor %}
{% endfor %}
"""
trim = true
footer = "<!-- generated by git-cliff -->"

header

Header text that will be added to the beginning of the changelog.

body

Body template that represents a single release in the changelog.

See templating for more detail.

trim

If set to true, leading and trailing whitespaces are removed from the body.

It is useful for adding indentation to the template for readability, as shown in the example.

footer

Footer text that will be added to the end of the changelog.

git

This section contains the parsing and git related configuration options.

[git]
conventional_commits = true
commit_parsers = [
    { message = "^feat", group = "Features"},
    { message = "^fix", group = "Bug Fixes"},
    { message = "^doc", group = "Documentation"},
    { message = "^perf", group = "Performance"},
    { message = "^refactor", group = "Refactor"},
    { message = "^style", group = "Styling"},
    { message = "^test", group = "Testing"},
]
filter_commits = false
tag_pattern = "v[0-9]*"
skip_tags = "v0.1.0-beta.1"

conventional_commits

If set to true, parses the commits according to the Conventional Commits specifications.

The Conventional Commits specification is a lightweight convention on top of commit messages. It provides an easy set of rules for creating an explicit commit history; which makes it easier to write automated tools on top of. This convention dovetails with SemVer, by describing the features, fixes, and breaking changes made in commit messages.

The commit message should be structured as follows:

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

e.g. feat(parser): add ability to parse arrays

commit_parsers

An array of commit parsers for determining the commit groups by using regex.

Examples:

{ message = "^feat", group = "Features"}
- Group the commit as "Features" if the commit message (description) starts with "feat".
{ body = ".*security", group = "Security"}
- Group the commit as "Security" if the commit body contains "security".
{ message = ".*deprecated", body = ".*deprecated", group = "Deprecation"}
- Group the commit as "Deprecation" if the commit body and message contains "deprecated".
{ message = "^revert", skip = true}
- Skip processing the commit if the commit message (description) starts with "revert".
{ message = "^doc", group = "Documentation", default_scope = "other"},
- If the commit starts with "doc", group the commit as "Documentation" and set the default scope to "other". (e.g. docs: xyz will be processed as docs(other): xyz)

filter_commits

If set to true, commits that are not matched by commit parsers are filtered out.

tag_pattern

A glob pattern for matching the git tags.

e.g. It processes the same tags as the output of the following git command:

git tag --list 'v[0-9]*'

skip_tags

A regex for skip processing the matched tags.

Templating

A template is a text where variables and expressions get replaced with values when it is rendered.

Context

Context is the model that holds the required data for a template rendering. The JSON format is used in the following examples for the representation of a context.

Conventional Commits

conventional_commits = true

For a conventional commit like this,

<type>[scope]: <description>

[body]

[footer(s)]

following context is generated to use for templating:

{
  "version": "v0.1.0-rc.21",
  "commits": [
    {
      "id": "e795460c9bb7275294d1fa53a9d73258fb51eb10",
      "group": "<type> (overrided by commit_parsers)",
      "scope": "[scope]",
      "message": "<description>",
      "body": "[body]",
      "footers": ["[footer]", "[footer]"],
      "breaking_description": "<description>",
      "breaking": false
    }
  ],
  "commit_id": "a440c6eb26404be4877b7e3ad592bfaa5d4eb210 (release commit)",
  "timestamp": 1625169301,
  "previous": {
    "version": "previous release"
  }
}

Breaking Changes

breaking flag is set to true when the commit has an exclamation mark after the commit type and scope, e.g.:

feat(scope)!: this is a breaking change

Or when the BREAKING CHANGE: footer is defined:

feat: add xyz

BREAKING CHANGE: this is a breaking change

breaking_description is set to the explanation of the breaking change. This description is expected to be present in the BREAKING CHANGE footer. However, if it's not provided, the message is expected to describe the breaking change.

Non-Conventional Commits

conventional_commits = false

If conventional_commits is set to false, then some of the fields are omitted from the context or squashed into the message field:

{
  "version": "v0.1.0-rc.21",
  "commits": [
    {
      "id": "e795460c9bb7275294d1fa53a9d73258fb51eb10",
      "group": "(overrided by commit_parsers)",
      "message": "(whole commit message including description, footers, etc.)"
    }
  ],
  "commit_id": "a440c6eb26404be4877b7e3ad592bfaa5d4eb210 (release commit)",
  "timestamp": 1625169301,
  "previous": {
    "version": "previous release"
  }
}

Syntax

git-cliff uses Tera as the template engine. It has a syntax based on Jinja2 and Django templates.

There are 3 kinds of delimiters and those cannot be changed:

{{ and }} for expressions
{% or {%- and %} or -%} for statements
{# and #} for comments

See the Tera Documentation for more information about control structures, built-ins filters, etc.

Custom built-in filters that git-cliff uses:

upper_first: Converts the first character of a string to uppercase.

Examples

Examples are based on the following Git history:

* df6aef4 (HEAD -> master) feat(cache): use cache while fetching pages
* a9d4050 feat(config): support multiple file formats
* 06412ac (tag: v1.0.1) chore(release): add release script
* e4fd3cf refactor(parser): expose string functions
* ad27b43 (tag: v1.0.0) docs(example)!: add tested usage example
* 9add0d4 fix(args): rename help argument due to conflict
* a140cef feat(parser): add ability to parse arrays
* 81fbc63 docs(project): add README.md
* a78bc36 Initial commit

See examples directory for example configuration files.
