bumpversion 0.4.0

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

• not specific to any programming language, just handles text files.

Screencast

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

bumpversion [options] part [file [file ...]]

Config file .bumpversion.cfg

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
files = setup.py
commit = True
tag = True

Options

part

Part of the version to increase.

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

Example bumping to 0.6.0:

bumpversion --current-version 0.5.1 minor setup.py

Example bumping to 2.0.0:

bumpversion --current-version 1.1.9 major setup.py

[file [file ...]] / files =

default: empty

The files where to search and replace version strings

Command line example:

bumpversion patch setup.py src/VERSION.txt

Config file example:

[bumpversion]
files = setup.py src/VERSION.txt

--current-version / current_version =

no default value

The current version of the software package.

Example:

bumpversion --current-version 0.5.1 patch setup.py

--new-version / new_version =

no default value

The version of the software after the increment

Example (Go from 0.5.1 directly to 0.6.1):

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

--parse / 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.

--serialize / 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.

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

Multiple values on the command line are given like --serialize {major}.{minor} --serialize {major}, the configuration file uses multiple lines:

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

(--tag | --no-tag) / tag = (True | False)

default: 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.

--tag-name / 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}).

Example:

bumpversion --message 'Jenkins Build {$BUILD_NUMBER}: {new_version}' patch

(--commit | --no-commit) / commit = (True | False)

default: Don’t create a commit

Whether to create a commit

--message / 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}).

Example:

bumpversion --message '[{now:%Y-%m-%d}] Jenkins Build {$BUILD_NUMBER}: {new_version}' patch

--dry-run, -n

Don’t touch any files, just pretend. Best used with ‘–verbose’.

--verbose

Print useful information to stderr

-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

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
