A small command line tool to bump tracked versions in your repository.

It is designed to integrate well with your CI/CD pipeline. Simply install and run bumpit as part of your pipeline. Let the robots do the boring work!

You can download and install bumpit from PyPI by running:

pip install bumpit

There are two ways to use bumpit

1. through the command line, or
2. through your python code

At a high level, you need to

1. setup the configuration file .bumpconfig.yaml in your target folder.
2. run bumpit or use in the code

Usage: bumpit [OPTIONS]

Options:
  -c, --config PATH  (optional) configuration settings. Defaults to
                     `.bumpit.yaml`
  -p, --part TEXT    (optional) strategy part override. Defaults to
                     `strategy.part` from the config file.
  -v, --value TEXT   (optional) part value override. Any part can be overrode
                     by this value as long as the value is valid.
  -d, --dry-run      (optional) run the tool in dry run mode. Defaults to
                     false.
  --help             Show this message and exit.

Just do from bumpit.core.bumpit import run in your code.

Check out the bumpit cli code for concrete example.

bumpit relies heavily on a configuration file to capture runtime context of bumpit. This config file is named .bumpconfig.yaml by default. You can override this using the --config option in the command line.

The config file looks like:

current_version: "201910.1.0"
base_branch: "master"
strategy:
  name: "calver"
  part: "minor"
  version_format: "YYYYMM.MINOR.MICRO"
commit:
  author: "Jane Doe <jane@doe.com>"
tag:
  apply: True
  format: "{version}"
auto_remote_push: True  # or False
tracked_files:
- setup.py

where:

• current_version - the current version of your files. It needs to be wrapped in quotes to force parsing to be string (e.g. avoid calver current_version to be parsed as float)
• base_branch - The name of base branch in the repository. Default value is master if it is not specified.
• strategy - strategy section
  • name - supported values: semver, calver
  • part - the target part to update when bumpit runs. Please refer to the description below for strategy specific values.
  • version_format - the format of the version. This only applies for calver
• commit - commit section
  • author - string value using the standard git author format A U Thor <author@example.com>
• tag - tag section
  • apply - bool value to instruct the tool to tag the repository after the version update
  • format - format of the tag. Some people prefer to add prefix to their tag versions (e.g. release/1.0.1). As long as the {version} is present, then it is a valid tag_format
• auto_remote_push - bool flag that guards whether to push commit and/or tag changes to remote repository. It should never be wrapped in quotes so that it will be properly parsed as a bool
• tracked_files - a list of relative filenames to update version to. If the current_version is not found, the tool simply skips this file

• Collision of versions is handled outside of bumpit. Other tools such as a good version control system fits better in solving this problem.

Check out the following repositories for examples:

• CalVer example
• SemVer example
• bumpit - yep! bumpit uses bumpit.

The tool currently supports the following versioning strategies

• Semantic Version
• Calendar Version

bumpit fully supports strict semver specification defined in semver.org. It validates the right format using the semver.org proposed format.

Here is an example of a configuration file for semver.

Important notes on configuration:

• strategy.name must be semver
• strategy.part supported values are major, minor, patch
• startegy.version_format does not apply to semver. It is completely ignored in the code. It is safe (and better) to not include this section for semver use case to avoid confusing the user.

Any semver part can be updated by giving bumpit a specific value to update the part to. This can be done through:

• command line by using the --part and --value cli options, or
• program by providing the target_part and force_value in bumpit#run method

Due to the free form nature of the pre_release and build_metadata parts, they can only be updated through the force method described above.

However, the biggest gain from using bumpit is to let the tool auto update your versions for you.

Out of the box, bumpit can auto update the major, minor, and the patch parts of semver. To accomplish this, specify the target part in the config file strategy.part section.

bumpit supports calver specification defined in calver.org and covers use cases described in the specification website.

Here is an example of a configuration file for calver.

Important notes on configuration:

• strategy.name must be calver
• strategy.part supported values are auto, date, major, minor, micro
• startegy.version_format combination of calver parts. Note that bumpit does check that only one representation of part is present in the format. For example, you cannot have MM and 0M in the same token because they both refer to month.

See calver scheme for supported formats.

Any calver part can be updated by giving bumpit a specific value to update the part to. This can be done through:

• command line by using the --part and --value cli options, or
• program by providing the target_part and force_value in bumpit#run method

Due to the free form nature of the modifier, this can only be updated through the force method described above.

However, the biggest gain from using bumpit is to let the tool auto update your versions for you.

Out of the box, bumpit can auto update the auto, date, major, minor, and the micro parts of calver. To accomplish this, specify the target part in the config file strategy.part section. This is also the order of precedence when updating the parts. Updating the higher precedent part resets the lower precedent parts. For example, if the date is update, then all major, minor, micro, modifier will be reset to their respective default values.

Reset values:

• major resets to 0
• minor resets to 0
• micro resets to 0
• modifier resets to an empty string ""

Code and documentation improvements are all welcome. You can also file bug reports or feature suggestions.

The feature set is meant to handle different versioning strategies. Currently, the strategies I know are applied in the wild are implemented, but it is by no means complete!

To publish bumpit, run the following

git checkout master
git pull
bumpit
python setup.py bdist_wheel sdist
twine upload dist/*
