bumpversion 0.5.2

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}

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 occurences. 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.
