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

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 and dev releases are not supported yet.

Usage

$ cz bump --help
usage: cz bump [-h] [--dry-run] [--files-only] [--changelog] [--no-verify]
               [--yes] [--tag-format TAG_FORMAT] [--bump-message BUMP_MESSAGE]
               [--prerelease {alpha,beta,rc}]
               [--increment {MAJOR,MINOR,PATCH}] [--check-consistency]

optional arguments:
  -h, --help            show this help message and exit
  --dry-run             show output to stdout, no commit, no modified files
  --files-only          bump version in the files from the config
  --changelog, -ch      generate the changelog for the newest version
  --no-verify           this option bypasses the pre-commit and commit-msg
                        hooks
  --yes                 accept automatically questions done
  --tag-format TAG_FORMAT
                        the format used to tag the commit and read it, use it
                        in existing projects, wrap around simple quotes
  --bump-message BUMP_MESSAGE
                        template used to create the release commit, useful
                        when working with CI
  --prerelease {alpha,beta,rc}, -pr {alpha,beta,rc}
                        choose type of prerelease
  --increment {MAJOR,MINOR,PATCH}
                        manually specify the desired increment
  --check-consistency, -cc
                        check consistency among versions defined in commitizen
                        configuration and version_files

--changelog

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

--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,

and setup.py.

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

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"

In your pyproject.toml or .cz.toml

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

The variables must be preceded by a $ sign.

Supported variables:

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

Some examples

pyproject.toml or .cz.toml

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