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

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]
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
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]
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]
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]
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]
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

`tag_message =`

[optional]
default: Bump version: {current_version} → {new_version}

The tag message to use when creating a tag. 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-message. Example usage: bump2version --tag-message 'Release {new_version}' patch

bump2version creates an annotated tag in Git by default. To disable this and create a lightweight tag, you must explicitly set an empty tag_message:

either in the configuration file: tag_message =
or in the command-line: bump2version --tag-message ''

You can read more about Git tagging here.

`commit = (True | False)`

[optional]
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]
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]
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}

[bumpversion:part:release]
optional_value = gamma
values =
  alpha
  beta
  gamma

Here, bump2version release would bump 1.alpha to 1.beta. Executing bump2version release again would bump 1.beta to 1, because release being gamma is configured optional.

You should consider the version of 1 to technically be 1.gamma with the .gamma part not being serialized since it is optional. The {num} entry in the serialize list allows the release part to be hidden. If you only had {num}.{release}, an optional release will always be serialized.

Attempting to bump the release when it is the value of gamma will cause a ValueError as it will think you are trying to exceed the values list of the release part.

`first_value =`

default: The first entry in values =.

When the part is reset, the value will be set to the value specified here.

Example:

[bumpversion]
current_version = 1.alpha1
parse = (?P<num>\d+)(\.(?P<release>.*)(?P<build>\d+))?
serialize =
  {num}.{release}{build}

[bumpversion:part:release]
values =
  alpha
  beta
  gamma

[bumpversion:part:build]
first_value = 1

Here, bump2version release would bump 1.alpha1 to 1.beta1.

Without the first_value = 1 of the build part configured, bump2version release would bump 1.alpha1 to 1.beta0, starting the build at 0.

`independent =`

default: False

When this value is set to True, the part is not reset when other parts are incremented. Its incrementation is independent of the other parts. It is in particular useful when you have a build number in your version that is incremented independently of the actual version.

Example:

[bumpversion]
current_version: 2.1.6-5123
parse = (?P<major>\d+)\.(?P<minor>\d+)\.(?P<patch>\d+)\-(?P<build>\d+)
serialize = {major}.{minor}.{patch}-{build}

[bumpversion:file:VERSION.txt]

[bumpversion:part:build]
independent = True

Here, bump2version build would bump 2.1.6-5123 to 2.1.6-5124. Executingbump2version major would bump 2.1.6-5124 to 3.0.0-5124 without resetting the build number.

Configuration file -- File specific configuration

This configuration is in the section: [bumpversion:file:…] or [bumpversion:glob:…]

Both, file: and glob: are configured the same. Their difference is that file will match file names directly like requirements.txt. While glob also matches multiple files via wildcards like **/pom.xml.

Note: The configuration file format requires each section header to be unique. If you want to process a certain file multiple times, you may append a description between parens to the file keyword: [bumpversion:file (special one):…].

`parse =`

default: (?P<major>\d+)\.(?P<minor>\d+)\.(?P<patch>\d+)

Regular expression (using Python regular expression syntax) on how to find and parse the version string.

Is required to parse all strings produced by serialize =. Named matching groups ("(?P<name>...)") provide values to as the part argument.

Also available as --parse

`serialize =`

default: {major}.{minor}.{patch}

Template specifying how to serialize the version parts back to a version string.

This is templated using the Python Format String Syntax. Available in the template context are parsed values of the named groups specified in parse = as well as all environment variables (prefixed with $).

Can be specified multiple times, bumpversion will try the serialization formats beginning with the first and choose the last one where all values can be represented like this:

serialize =
  {major}.{minor}
  {major}

Given the example above, the new version 1.9 will be serialized as 1.9, but the version 2.0 will be serialized as 2.

Also available as --serialize. Multiple values on the command line are given like --serialize {major}.{minor} --serialize {major}

`search =`

default: {current_version}

Template string how to search for the string to be replaced in the file. Useful if the remotest possibility exists that the current version number might be present multiple times in the file and you mean to only bump one of the occurrences. Can be multiple lines, templated using Python Format String Syntax

`replace =`

default: {new_version}

Template to create the string that will replace the current version number in the file.

Given this requirements.txt:

Django>=1.5.6,<1.6
MyProject==1.5.6

using this .bumpversion.cfg will ensure only the line containing MyProject will be changed:

[bumpversion]
current_version = 1.5.6

[bumpversion:file:requirements.txt]
search = MyProject=={current_version}
replace = MyProject=={new_version}

Can be multiple lines, templated using Python Format String Syntax.

NOTE: (Updated in v1.0.1) It is important to point out that if a custom search pattern is configured, then bump2version will only perform a change if it finds an exact match and will not fallback to the default pattern. This is to prevent accidentally changing strings that match the default pattern when there is a typo in the custom search pattern.

For example, if the string to be replaced includes literal quotes, the search and replace patterns must include them too to match. Given the file version.sh:

  MY_VERSION="1.2.3"

Then the following search and replace patterns (including quotes) would be required:

[bumpversion:file:version.sh]
search = MY_VERSION="{current_version}"
replace = MY_VERSION="{new_version}"

Command-line Options

Most of the configuration values above can also be given as an option on the command-line. Additionally, the following options are available:

--dry-run, -n Don't touch any files, just pretend. Best used with --verbose.

--allow-dirty Normally, bumpversion will abort if the working directory is dirty to protect yourself from releasing unversioned files and/or overwriting unsaved changes. Use this option to override this check.

--no-configured-files Will not update/check files specified in the .bumpversion.cfg. Similar to dry-run, but will also avoid checking the files. Also useful when you want to update just one file with e.g., bump2version --no-configured-files major my-file.txt

--verbose Print useful information to stderr

--list List machine readable information to stdout for consumption by other programs.

Example output:

current_version=0.0.18
new_version=0.0.19

-h, --help Print help and exit

Using bumpversion in a script

If you need to use the version generated by bumpversion in a script you can make use of the --list option, combined with grep and sed.

Say for example that you are using git-flow to manage your project and want to automatically create a release. When you issue git flow release start you already need to know the new version, before applying the change.

The standard way to get it in a bash script is

bump2version --dry-run --list <part> | grep <field name> | sed -r s,"^.*=",,

where part is as usual the part of the version number you are updating. You need to specify --dry-run to avoid bumpversion actually bumping the version number.

For example, if you are updating the minor number and looking for the new version number this becomes

bump2version --dry-run --list minor | grep new_version | sed -r s,"^.*=",,

Using bumpversion to maintain a go.mod file within a Go project

In a module-aware Go project, when you create a major version of your module beyond v1, your module name will need to include the major version # (e.g. github.com/myorg/myproject/v2).

You can use bump2version to maintain the major version # within the go.mod file by using the parse and serialize options, as in this example:

Example .bumpversion.cfg file:

    [bumpversion]
    current_version = 2.0.0
    commit = True

    [bumpversion:file:go.mod]
    parse = (?P<major>\d+)
    serialize = {major}
    search = module github.com/myorg/myproject/v{current_version}
    replace = module github.com/myorg/myproject/v{new_version}

Example go.mod file:

    module github.com/myorg/myproject/v2

    go 1.12

    require (
        ...
    )

Then run this command to create version 3.0.0 of your project:

    bump2version --new-version 3.0.0 major

Your go.mod file now contains this module directive:

    module github.com/myorg/myproject/v3
