Overview

Oh, no! Not another version bump utility!

version_bumper is a PyPA Version compliant bumper that can bump (increment by 1) any part of the version and supports pyproject.toml's project.version and tool.poetry.version key/value pairs.

What this means is:

• version_bumper fully complies with the version definition in the Python Packaging Authority's (PyPA) (https://www.pypa.io/) Python Packaging User Guide Version specifiers specification (originally PEP440).

• version_bumper manages the version(s) in the pyproject.toml file.

  • Poetry uses the key/value pair tool.poetry.version (expecting this to change when version 2 is released)
  • other tools use the current PyPA standard key/value pair project.version
  • project.version is required to exist.
  • if tool.poetry.version exists, then it will be updated when project.version is updated.
  • if tool.poetry.version does not exist, then version_bumper will NOT create it.

• version_bumper lets you set or bump individual parts of the version as well as setting or getting the full version.

• version_bumper supports input and output in json, text (for bash scripts), or human-readable console.

• version_bumper has a full suite (100% coverage) of tests that serve as both examples and validation.

Usage

Let's demonstrate what version_bumper can do.

➤ version_bumper
usage: Version Bumper [-h] [--config FILE] [--save-config] [--save-config-as FILE] [-v] [--longhelp] [--loglevel {DEBUG,INFO,WARNING,ERROR,CRITICAL}] [--debug] [--quiet] [--logfile LOGFILE]
                      {bump,version,set,get,release} ...
Version Bumper: error: A command argument (set, get, bump, release, version) or an informational option (--help, --longhelp, --version) is required

OK, so we have to give it a command or an informational option. I'll leave the informational options as an exercise for the reader.

Valid help commands are:

➤ version_bumper --help
➤ version_bumper set --help
➤ version_bumper get --help
...

Let's get the version(s):

➤ version_bumper get
project.version: 0.1.1
tool.poetry.version: 0.1.1

and as json:

➤ version_bumper get --json
{"project.version": "0.1.1", "tool.poetry.version": "0.1.1"}

and as text:

➤ version_bumper get --text
0.1.1
0.1.1

For getting the version in a bash script, you probably want to specify which version and get just a single value:

➤ PROJECT_VERSION=$(version_bumper get --text --project)
➤ echo $PROJECT_VERSION
0.1.1

Setting the version(s) in the pyproject is simple:

➤ version_bumper version "1.2.3a4+54321" --json
{"version": "1.2.3a4+54321"}

Setting the prerelease part of the version without change any other part:

➤ version_bumper set a 5 --json
{"version": "1.2.3a5+54321"}

Now let's say we want to bump the pre-release (a5):

➤ version_bumper bump a --json
{"version": "1.2.3a6"}

Notice bumping clears everything to the right, unless you are bumping the epoch:

➤ version_bumper bump epoch
version: 1!1.2.3a6

The set command can optional clear everything to the right:

➤ version_bumper bump dev
version: 1!1.2.3a6.dev1
➤ version_bumper set local "foo0123"
version: 1!1.2.3a6.dev1+foo0123
➤ version_bumper set minor 4
version: 1!1.4.3a6.dev1+foo0123
➤ version_bumper set minor 5 --clear-right
version: 1!1.5.0

Let's set the epoch back to 0:

➤ version_bumper set epoch 0
version: 1.5.0

And now make it a release candidate:

➤ version_bumper bump rc --json
{"version": "1.5.0rc1"}

Finally let's make it the release version:

➤ version_bumper release --json
{"version": "1.5.0"}

Please see the unit tests in tests/ directory for more examples.

Installation

PyPI Installation

pip install version_bumper

Development Installation

Development Prerequisites

• Install the task manager: Task

• Optionally install pyenv-installer

  • Install dependent pythons, example:

    pyenv local 3.11.9 3.12.3

  Note you may need to install some libraries for the pythons to compile cleanly. For example on ubuntu (note I prefer nala over apt):

  sudo nala install tk-dev libbz2-dev libreadline-dev libsqlite3-dev lzma-dev python3-tk libreadline-dev

• Recommended to upgrade pip to latest.

• Optionally install Poetry

• Optionally install Hatch

• Optionally install setuptools

  • Install build

Install the package using your favorite dev tool. Examples:

• git clone [e-mail]:royw/version_bumper.git
• cd version_bumper
• task init
• task build

Note, task init will run git init ., git add the initial project files, and do a git commit. If you are using another VCS, please first edit the init task in the Taskfile.yaml file.

See the Developer README for detailed information on the development environment.
