Semversioner

The easiest way to manage semantic versioning in your project and generate CHANGELOG.md file automatically.

Semversioner will provide the tooling to automate semver release process for libraries, docker images, etc.

This project was inspired by the way AWS manages their versioning for AWS-cli.

Semantic Versioning

The semantic versioning spec involves several possible variations, but to simplify, in Semversioner we are using the three-part version number:

<major>.<minor>.<patch>

Constructed with the following guidelines:

Breaking backward compatibility or major features bumps the major (and resets the minor and patch).
New additions without breaking backward compatibility bumps the minor (and resets the patch).
Bug fixes and misc changes bumps the patch.

An example would be 1.0.0

How it works

At any given time, the .semversioner/ directory looks like:

.semversioner
└── next-release
    ├── minor-20181227010225.json
    └── major-20181228010225.json
├── 1.1.0.json
├── 1.1.1.json
├── 1.1.2.json

The release process takes everything in next-release and aggregates them all together in a single JSON file for that release (e.g 1.12.0.json). This JSON file is a list of all the individual JSON files from next-release.

Install

$ pip install semversioner

Usage

Bumping the version

In your local environment your will use the CLI to create the different changeset files that will be committed with your code. For example:

$ semversioner add-change --type patch --description "Fix security vulnerability with authentication."

Then, in your CI/CD tool you will need to release (generating automatically version number) and creating the the changelog file.

$ semversioner release

Generating Changelog

As a part of your CI/CD workflow, you will be able to generate the changelog file with all changes.

$ semversioner changelog > CHANGELOG.md

You can customize the changelog by creating a template and passing it as parameter to the command. For example:

$ semversioner changelog --template .semversioner/config/template.j2

The template is using Jinja2, a templating language for Python. For example:

# Changelog
{% for release in releases %}

## {{ release.version }}

{% for change in release.changes %}
- {{ change.type }}: {{ change.description }}
{% endfor %}
{% endfor %}

You can filter the changelog by only showing changes for a specific version:

$ semversioner changelog --version "1.0.0"

Alternatively, you can use the following command to filter changes by the last released version:

$ semversioner changelog --version $(semversioner current-version)

Getting next version

As part of the CI/CD workflow, sometimes you want to release dev, rc, or other pre-release packages. For this purpose, the next-version command can be issued, to compute the next version based on the current change set. This will not change any files on disk, and they are as such preserved for any future release.

$ semversioner next-version
