bumpversion 0.5.0

Version-bump your software with a single command!

Latest Version: 0.5.1

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

Installation

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

pip install --upgrade bumpversion

Usage

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

bumpversion [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:

bumpversion --current-version 0.5.1 minor src/VERSION
[file]

default: none (optional)

The file that will be modified.

If not given, the list of [bumpversion:file:…] sections from the configuration file will be used. If no files are mentioned on the configuration file either, are no files will be modified.

Example bumping 1.1.9 to 2.0.0:

bumpversion --current-version 1.1.9 major setup.py

Configuration

All options can optionally be specified in a config file called .bumpversion.cfg so that once you know how bumpversion 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]

Global configuration

General configuration is grouped in a [bumpversion] section.

current_version =

no default value (required)

The current version of the software package before bumping.

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

new_version =

no default value (optional)

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: bumpversion --current-version 0.5.1 --new-version 0.6.1 patch setup.py).

tag = (True | False)

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).

tag_name =

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 all environment variables (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 --tag-name (e.g. bumpversion --message 'Jenkins Build {$BUILD_NUMBER}: {new_version}' patch).

commit = (True | False)

default: False (Don’t create a commit)

Whether to create a commit using git or Mercurial.

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

message =

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 all environment variables (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 --message (e.g.: bumpversion --message '[{now:%Y-%m-%d}] Jenkins Build {$BUILD_NUMBER}: {new_version}' patch)

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 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. it’s 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, bumpversion release would bump 1.alpha to 1.beta. Executing bumpversion release again would bump 1.beta to 1, because release being gamma is configured optional.

first_value =

default: The first entry in values =.

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

File specific configuration

[bumpversion:file:…]

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 it 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}

Options

Most of the configuration values above can also be given as an option. 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.
--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

Development

Development of this happens on GitHub, patches including tests, documentation are very welcome, as well as bug reports! Also please open an issue if this tool does not support every aspect of bumping versions in your development workflow, as it is intended to be very versatile.

Changes

unreleased

v0.5.0

This is a major one, containing two larger features, that require some changes in the configuration format. This release is fully backwards compatible to v0.4.1, however deprecates two uses that will be removed in a future version.

  • New feature: Part specific configuration
  • New feature: File specific configuration
  • New feature: parse option can now span multiple line (allows to comment complex regular expressions. See re.VERBOSE in the Python documentation for details, this testcase as an example.)
  • New feature: --allow-dirty (#42).
  • Fix: Save the files in binary mode to avoid mutating newlines (thanks @jaraco #45).
  • License: bumpversion is now licensed under the MIT License (#47)
  • Deprecate multiple files on the command line (use a configuration file instead, or invoke bumpversion multiple times)
  • Deprecate ‘files =’ configuration (use file specific configuration instead)

v0.4.1

  • Add –list option (#39)
  • Use temporary files for handing over commit/tag messages to git/hg (#36)
  • Fix: don’t encode stdout as utf-8 on py3 (#40)
  • Fix: logging of content of config file was wrong

v0.4.0

  • Add –verbose option (#21 #30)
  • Allow option –serialize multiple times

v0.3.8

  • Fix: –parse/–serialize didn’t work from cfg (#34)

v0.3.7

  • Don’t fail if git or hg is not installed (thanks @keimlink)
  • “files” option is now optional (#16)
  • Fix bug related to dirty work dir (#28)

v0.3.6

  • Fix –tag default (thanks @keimlink)

v0.3.5

  • add {now} and {utcnow} to context
  • use correct file encoding writing to config file. NOTE: If you are using Python2 and want to use UTF-8 encoded characters in your config file, you need to update ConfigParser like using ‘pip install -U configparser’
  • leave current_version in config even if available from vcs tags (was confusing)
  • print own version number in usage
  • allow bumping parts that contain non-numerics
  • various fixes regarding file encoding

v0.3.4

  • bugfix: tag_name and message in .bumpversion.cfg didn’t have an effect (#9)

v0.3.3

  • add –tag-name option
  • now works on Python 3.2, 3.3 and PyPy

v0.3.2

  • bugfix: Read only tags from git describe that look like versions

v0.3.1

  • bugfix: --help in git workdir raising AssertionError
  • bugfix: fail earlier if one of files does not exist
  • bugfix: commit = True / tag = True in .bumpversion.cfg had no effect

v0.3.0

  • BREAKING CHANGE The --bump argument was removed, this is now the first positional argument. If you used bumpversion --bump major before, you can use bumpversion major now. If you used bumpversion without arguments before, you now need to specify the part (previous default was patch) as in bumpversion patch).

v0.2.2

  • add –no-commit, –no-tag

v0.2.1

  • If available, use git to learn about current version

v0.2.0
