ADVbumpversion

This Fork

This is a fork (ADVbumpversion) of a fork (bump2version).

The excellent original project that can be found here: https://github.com/peritus/bumpversion. Unfortunately it seems like development has been stuck for some time and no activity has been seen from the author.

Christian Verkerk has made some Pull Request merges and this project (renamed bump2version) can be found here: https://github.com/c4urself/bump2version.

I have merged other Push Requests, in particular the ability to have more than one rule for a file, in a new project ADVbumpversion. The major differences are:

  • It is possible to have more than one set of rules (parse, serialize, search and replace) for the

same file

  • Some parts of the version can be independent of the others: They are not incremented with the other parts. It is in

particular useful when you have a build number that is incremented independently of the version

  • Several examples of usage
  • More testing cases

Look at CHANGELOG.rst to see all the changes.

Note: For compatibility, this project declares advbumpversion, bump2version and bumpversion. They are identical. The remaining of this document uses bumpversion in command-line examples.

Introduction

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

Installation

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

pip install --upgrade advbumpversion

Usage

Note: I have compiled several usage examples in EXAMPLES.rst.

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]

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

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).

sign_tags = (True | False)

default: False (Don't sign tags)

Whether to sign tags.

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

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).

tag_message =

default: Bump version: {current_version} -> {new_version}

The annotation 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-message.

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.

``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.

File specific configuration

[bumpversion:file:…:…]

Note: If you want to specify different options (parse, ...) for the same file, you can have several sections for the same file. To distinguish these sections, append : and an identifier (its value has no importance) after the file name:

[bumpversion:file.txt:0]
parse = ...

[bumpversion:file.txt:1]
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.

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}

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 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.

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

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

bumpversion --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

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

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.

How to release bumpversion itself

Execute the following commands:

git checkout master
git pull
make test
bumpversion release
python setup.py sdist bdist_wheel upload
bumpversion --no-tag patch
git push origin master --tags
