About

The version is bumped automatically based on the commits.

The commits should follow the rules of the committer to be parsed correctly.

It is possible to specify a prerelease (alpha, beta, release candidate) version.

The version can also be manually bumped.

The version format follows semantic versioning.

This means MAJOR.MINOR.PATCH

Increment	Description	Conventional commit map
`MAJOR`	Breaking changes introduced	`BREAKING CHANGE`
`MINOR`	New features	`feat`
`PATCH`	Fixes	`fix` + everything else

Prereleases are supported following python's PEP 0440

The scheme of this format is

[N!]N(.N)*[{a|b|rc}N][.postN][.devN]

Some examples:

0.9.0
0.9.1
0.9.2
0.9.10
0.9.11
1.0.0a0  # alpha
1.0.0a1
1.0.0b0  # beta
1.0.0rc0 # release candidate
1.0.0rc1
1.0.0
1.0.1
1.1.0
2.0.0
2.0.1a

post releases are not supported yet.

`--files-only`

Bumps the version in the files defined in version_files without creating a commit and tag on the git repository,

cz bump --files-only

`--changelog`

Generate a changelog along with the new version and tag when bumping.

cz bump --changelog

`--check-consistency`

Check whether the versions defined in version_files and the version in commitizen configuration are consistent before bumping version.

cz bump --check-consistency

For example, if we have pyproject.toml

[tool.commitizen]
version = "1.21.0"
version_files = [
    "src/__version__.py",
    "setup.py",
]

src/__version__.py,

__version__ = "1.21.0"

and setup.py.

...
    version="1.0.5"
...

If --check-consistency is used, commitizen will check whether the current version in pyproject.toml exists in all version_files and find out it does not exist in setup.py and fails. However, it will still update pyproject.toml and src/__version__.py.

To fix it, you'll first git checkout . to reset to the status before trying to bump and update the version in setup.py to 1.21.0

`--local-version`

Bump the local portion of the version.

cz bump --local-version

For example, if we have pyproject.toml

[tool.commitizen]
version = "5.3.5+0.1.0"

If --local-version is used, it will bump only the local version 0.1.0 and keep the public version 5.3.5 intact, bumping to the version 5.3.5+0.2.0.

`--annotated-tag`

If --annotated-tag is used, commitizen will create annotated tags. Also available via configuration, in pyproject.toml or .cz.toml.

`--changelog-to-stdout`

If --changelog-to-stdout is used, the incremental changelog generated by the bump will be sent to the stdout, and any other message generated by the bump will be sent to stderr.

If --changelog is not used with this command, it is still smart enough to understand that the user wants to create a changelog. It is recommened to be explicit and use --changelog (or the setting update_changelog_on_bump).

This command is useful to "transport" the newly created changelog. It can be sent to an auditing system, or to create a Github Release.

Example:

cz bump --changelog --changelog-to-stdout > body.md

`--retry`

If you use tools like pre-commit, add this flag. It will retry the commit if it fails the 1st time.

Useful to combine with code formatters, like Prettier.

`--major-version-zero`

A project in its initial development should have a major version zero, and even breaking changes should not bump that major version from zero. This command ensures that behavior.

If --major-version-zero is used for projects that have a version number greater than zero it fails. If used together with a manual version the command also fails.

We recommend setting major_version_zero = true in your configuration file while a project is in its initial development. Remove that configuration using a breaking-change commit to bump your project’s major version to v1.0.0 once your project has reached maturity.

Avoid raising errors

Some situations from commitizen rise an exit code different than 0. If the error code is different than 0, any CI or script running commitizen might be interrupted.

If you have special use case, where you don't want one of this error codes to be raised, you can tell commitizen to not raise them.

Recommended use case

At the moment, we've identified that the most common error code to skip is

Error name	Exit code
NoneIncrementExit	21

There are some situations where you don't want to get an error code when some commits do not match your rules, you just want those commits to be skipped.

cz -nr 21 bump

Easy way

Check which error code was raised by commitizen by running in the terminal

echo $?

The output should be an integer like this

And then you can tell commitizen to ignore it:

cz --no-raise 3

You can tell commitizen to skip more than one if needed:

cz --no-raise 3,4,5

Longer way

Check the list of exit_codes and understand which one you have to skip and why.

Remember to document somewhere this, because you'll forget.

For example if the system raises a NoneIncrementExit error, you look it up on the list and then you can use the exit code:

cz -nr 21 bump

Configuration

`tag_format`

It is used to read the format from the git tags, and also to generate the tags.

Commitizen supports 2 types of formats, a simple and a more complex.

cz bump --tag-format="v$version"

cz bump --tag-format="v$minor.$major.$patch$prerelease.$devrelease"

In your pyproject.toml or .cz.toml

[tool.commitizen]
tag_format = "v$major.$minor.$patch$prerelease"

The variables must be preceded by a $ sign.

Supported variables:

Variable	Description
`$version`	full generated version
`$major`	MAJOR increment
`$minor`	MINOR increment
`$patch`	PATCH increment
`$prerelease`	Prerelease (alpha, beta, release candidate)
`$devrelease`	Development release

`version_files` *

It is used to identify the files which should be updated with the new version. It is also possible to provide a pattern for each file, separated by colons (:).

Commitizen will update it's configuration file automatically (pyproject.toml, .cz) when bumping, regarding if the file is present or not in version_files.

* Renamed from files to version_files.

Some examples

pyproject.toml or .cz.toml

[tool.commitizen]
version_files = [
    "src/__version__.py",
    "setup.py:version"
]

In the example above, we can see the reference "setup.py:version". This means that it will find a file setup.py and will only make a change in a line containing the version substring.

`bump_message`

Template used to specify the commit message generated when bumping.

defaults to: bump: version $current_version → $new_version

Variable	Description
`$current_version`	the version existing before bumping
`$new_version`	version generated after bumping

Some examples

pyproject.toml or .cz.toml

[tool.commitizen]
bump_message = "release $current_version → $new_version [skip-ci]"

`update_changelog_on_bump`

When set to true the changelog is always updated incrementally when running cz bump, so the user does not have to provide the --changelog flag every time.

defaults to: false

[tool.commitizen]
update_changelog_on_bump = true

`annotated_tag`

When set to true commitizen will create annotated tags.

[tool.commitizen]
annotated_tag = true

`gpg_sign`

When set to true commitizen will create gpg signed tags.

[tool.commitizen]
gpg_sign = true

`major_version_zero`

When set to true commitizen will keep the major version at zero. Useful during the initial development stage of your project.

Defaults to: false

[tool.commitizen]
major_version_zero = true
