Bump My Version

image image image codecov GitHub Actions

NOTE

This is a maintained refactor of the bump2version fork of the excellent bumpversion project. The main goals of this refactor were:

  • Add support for pyproject.toml configuration files.
  • Convert to click for and rich for the CLI interface
  • Add better configuration validation using Pydantic
  • Make the code and tests easier to read and maintain

Overview

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 and optionally commit and tag the changes.

  • version formats are highly configurable
  • works without any source code manager, 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
  • supports Python 3.8+ and PyPy3.

Future Direction

  • Make it easier to get the current version
  • Switch having both the version part and files to change as arguments on the command line.
  • Make the version part argument truly optional when --new-version is specified
  • Allow for multiple tags, including one that moves for having a v2 that always points to the latest version of version 2. For example
  • Better UI with Rich

Installation

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

pip install --upgrade bump-my-version

Changelog

Please find the changelog here: CHANGELOG.md

Usage for version incrementing

NOTE:

Throughout this document, you can use bumpversion or bump-my-version interchangeably.

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

WARNING:

The invocation of bump-my-version changed in version 0.6.0. It split functionality into sub-commands. It remains backward-compatible with previous versions. Previous usage is discouraged and may be removed in a 1.0 release.

bump-my-version bump [options] [part] [file]

part

required

The part of the version to increase, e.g. minor.

Valid values include the named groups defined in the parse configuration.

Example bumping 0.5.1 to 0.6.0:

bump-my-version bump --current-version 0.5.1 minor

file

[optional]
default: none

Additional files to modify.

These files are added to the list of files specified in your configuration file. If you want to rewrite only files specified on the command line, also use --no-configured-files.

Example bumping 1.1.9 to 2.0.0:

bump-my-version bump --current-version 1.1.9 major setup.py

Configuration file

bump-my-version looks in four places for the configuration file to parse (in order of precedence):

  1. --config-file <FILE> (command line argument)
  2. BUMPVERSION_CONFIG_FILE=file (environment variable)
  3. .bumpversion.cfg (legacy)
  4. .bumpversion.toml
  5. setup.cfg (legacy)
  6. pyproject.toml

.toml files are recommended due to their type handling. We will likely drop support for ini-style formats in the future due to issues with formatting and parsing. You should add your configuration file to your source code management system.

By using a configuration file, you no longer need to specify those options on the command line. The configuration file also allows greater flexibility in specifying how files are modified.

Command-line Options

Most of the configuration values above can also be given as an option on the command line. Additionally, the following options are available:

--dry-run, -n Don't touch any files, just pretend. Best used with --verbose.

--no-configured-files Will not update/check files specified in the configuration file.

Similar to dry-run, but will also avoid checking the files. Also useful when you want to update just one file with e.g., bump-my-version --no-configured-files major my-file.txt

--verbose, -v Print useful information to stderr. If specified more than once, it will output more information.

--list DEPRECATED. Use bump-my-version show instead. 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 show subcommand.

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 need to know the new version before applying the change.

The standard way to get it in a bash script is

bump-my-version show new_version --increment <part>

where part is the part of the version number you are updating.

For example, if you are updating the minor number and looking for the new version number, this becomes:

$ bump-my-version show new_version --increment minor
1.1.0
