bump2version

NOTE

This is a maintained fork of the excellent bumpversion project.

Overview

Version-bump your software with a single command!

A small command line tool to simplify releasing software by updating all version strings in your source code by the correct increment. Also creates commits and tags:

• version formats are highly configurable
• works without any VCS, but happily reads tag information from and writes commits and tags to Git and Mercurial if available
• just handles text files, so it's not specific to any programming language
• supports Python 3 and PyPy3

If you want to use Python 2, use pip>=9 and you'll get the last supported version, or pin bump2version<1.

Alternatives

If bump2version does not fully suit your needs, you could take a look at other tools doing similar or related tasks: ALTERNATIVES.md.

Installation

You can download and install the latest version of this software from the Python package index (PyPI) as follows:

pip install --upgrade bump2version

NOTE: pip install bumpversion now installs the latest bump2version!

Usage

NOTE: Throughout this document you can use bumpversion or bump2version interchangeably.

There are two modes of operation: On the command line for single-file operation and using a configuration file (bumpversion.cfg) for more complex multi-file operations.

bump2version [options] part [file]

part

required<br />

The part of the version to increase, e.g. minor.

Valid values include those given in the --serialize / --parse option.

Example bumping 0.5.1 to 0.6.0:

 bump2version --current-version 0.5.1 minor src/VERSION

file

[optional]<br /> default: none

The file that will be modified.

This file is added to the list of files specified in [bumpversion:file:…] sections from the configuration file. If you want to rewrite only files specified on the command line, use --no-configured-files.

Example bumping 1.1.9 to 2.0.0:

 bump2version --current-version 1.1.9 major setup.py

Configuration file

All options can optionally be specified in a config file called .bumpversion.cfg so that once you know how bump2version needs to be configured for one particular software package, you can run it without specifying options later. You should add that file to VCS so others can also bump versions.

Options on the command line take precedence over those from the config file, which take precedence over those derived from the environment and then from the defaults.

Example .bumpversion.cfg:

[bumpversion]
current_version = 0.2.9
commit = True
tag = True

[bumpversion:file:setup.py]

If no .bumpversion.cfg exists, bump2version will also look into setup.cfg for configuration.

Configuration file -- Global configuration

General configuration is grouped in a [bumpversion] section.

current_version

required<br /> default: none

The current version of the software package before bumping.

Also available as --current-version (e.g. bump2version --current-version 0.5.1 patch setup.py)

new_version

[optional]<br /> default: none

The version of the software package after the increment. If not given will be automatically determined.

Also available as --new-version (e.g. to go from 0.5.1 directly to 0.6.1: bump2version --current-version 0.5.1 --new-version 0.6.1 patch setup.py).

tag = (True | False)

[optional]<br /> default: False (Don't create a tag)

Whether to create a tag, that is the new version, prefixed with the character "v". If you are using git, don't forget to git-push with the --tags flag.

Also available on the command line as (--tag | --no-tag).

sign_tags = (True | False)

[optional]<br /> default: False (Don't sign tags)

Whether to sign tags.

Also available on the command line as (--sign-tags | --no-sign-tags).

tag_name =

[optional]<br /> default: v{new_version}

The name of the tag that will be created. Only valid when using --tag / tag = True.

This is templated using the Python Format String Syntax. Available in the template context are current_version and new_version as well as current_[part] and new_[part] (e.g. 'current_major' or 'new_patch'). In addition, all environment variables are exposed, prefixed with $. You can also use the variables now or utcnow to get a current timestamp. Both accept datetime formatting (when used like as in {now:%d.%m.%Y}).

Also available as command-line flag tag-name. Example usage: bump2version --tag-name 'release-{new_version}' patch

In addition, it is also possible to provide a tag message by using --tag-message TAG_MESSAGE. Example usage: bump2version --tag-name 'release-{new_version}' --tag-message "Release {new_version}" patch

• If neither tag message or sign tag is provided, bumpversion uses a lightweight tag in Git. Otherwise, it utilizes an annotated Git tag. You can read more about Git tagging here.

commit = (True | False)

[optional]<br /> default: False (Don't create a commit)

Whether to create a commit using git or Mercurial.

Also available as (--commit | --no-commit).

In many projects it is common to have a pre-commit hook that runs prior to a commit and in case of failure aborts the commit. For some use cases it might be desired that when bumping a version and having commit = True, the pre-commit hook should perform slightly different actions than in regular commits. For example run an extended set of checks only for actual releases of the software. To allow the pre-commit hooks to distinguish a bumpversion commit, the BUMPVERSION_CURRENT_VERSION and BUMPVERSION_NEW_VERSION environment variables are set when executing the commit command.

message =

[optional]<br /> default: Bump version: {current_version} → {new_version}

The commit message to use when creating a commit. Only valid when using --commit / commit = True.

This is templated using the Python Format String Syntax. Available in the template context are current_version and new_version as well as current_[part] and new_[part] (e.g. 'current_major' or 'new_patch'). In addition, all environment variables are exposed, prefixed with $. You can also use the variables now or utcnow to get a current timestamp. Both accept datetime formatting (when used like as in {now:%d.%m.%Y}).

Also available as command-line flag --message. Example usage: bump2version --message '[{now:%Y-%m-%d}] Jenkins Build {$BUILD_NUMBER}: {new_version}' patch)

commit_args =

[optional<br /> default: empty

Extra arguments to pass to commit command. Only valid when using --commit / commit = True.

This is for example useful to add -s to generate Signed-off-by: line in the commit message.

Multiple arguments can be specified on separate lines.

Also available as command-line flag --commit-args, in which case only one argument can be specified.

Configuration file -- Part specific configuration

A version string consists of one or more parts, e.g. the version 1.0.2 has three parts, separated by a dot (.) character. In the default configuration these parts are named major, minor, patch, however you can customize that using the parse/serialize option.

By default all parts are considered numeric, that is their initial value is 0 and they are increased as integers. Also, the value 0 is considered to be optional if it's not needed for serialization, i.e. the version 1.4.0 is equal to 1.4 if {major}.{minor} is given as a serialize value.

For advanced versioning schemes, non-numeric parts may be desirable (e.g. to identify alpha or beta versions to indicate the stage of development, the flavor of the software package or a release name). To do so, you can use a [bumpversion:part:…] section containing the part's name (e.g. a part named release_name is configured in a section called [bumpversion:part:release_name].

The following options are valid inside a part configuration:

values =

default: numeric (i.e. 0, 1, 2, …)

Explicit list of all values that will be iterated when bumping that specific part.

Example:

[bumpversion:part:release_name]
values =
  witty-warthog
  ridiculous-rat
  marvelous-mantis

optional_value =

default: The first entry in values =.

If the value of the part matches this value it is considered optional, i.e. its representation in a --serialize possibility is not required.

Example:

[bumpversion]
current_version = 1.alpha
parse = (?P<num>\d+)(\.(?P<release>.*))?
serialize =
  {num}.{release}
  {num}
