🗞 Publicator

A better poetry publish experience.

PyPI - Python Version PyPI PyPI - Downloads PyPI - License Application Test Suite Libraries.io dependency status for latest release

While Poetry finally brings us a sane solution for publishing and maintaining Python packages, many developers crave for a more enhanced and safer user experience. Publicator aims to offer a convenient method for publishing your everyday libraries.

Publicator has been inspired by Sindre Sorhus' excellent np package for Node.js ecosystem and graciously funded by Futurice Spice Program.

Features

  • Ensures you are publishing from your release branch (main and master by default)
  • Ensures the working directory is clean and latest changes are pulled
  • Reinstalls dependencies to ensure your project works with the latest dependency tree
  • Ensures your Python version is supported by the project and its dependencies
  • Runs the tests with custom test script
  • Bumps the version in pyproject.toml and creates a Git tag based on it
  • Publishes the new version to Python Package Index or custom repository
  • Pushes commits and tags (newly & previously created) to your Git server
  • If the project is hosted on GitHub opens a prefilled GitHub Releases draft after publishing
  • Fully configurable via command-line arguments or the pyproject.toml file
  • See what will be executed with preview mode, without pushing or publishing anything remotely

Prerequisites

  • Python 3.8 or later
  • Poetry 1.1 or later
  • Git 2.11 or later

Install

Install or run directly using pipx, which manages an isolated virtual environment for you.

pipx install publicator
pipx run publicator <version>

Alternatively, add it as dependency to your Poetry project.

poetry add --dev publicator
poetry run publicator <version>

Usage

Publicator takes one command-line argument indicating the suitable version bump. It follows semantic versioning rules accurately.

# Release a new patch version (e.g. 1.0.0 -> 1.0.1)
publicator patch

# Release a new minor version (e.g. 1.0.1 -> 1.1.0)
publicator minor

# Release a new major version (e.g. 1.1.0 -> 2.0.0)
publicator major

Run publicator --help to see the full list of supported options:

Configuration

Publicator follows the pleasantly Pythonic way of specifying the configuration within pyproject.toml file. Below are the default configuration values.

[tool.publicator]
any-branch    = false
clean         = true
publish       = true
push          = true
release-draft = true
tag           = true
template      = "release: %s"

Values passed as command-line arguments take precedence over configuration file values.

Configuration enables for more granular usage. For example, in CI/CD pipelines you might want to disable publishing the package to registry or disable creating Git tags depending on your use case.

Preview Mode (Dry-Run)

If you'd rather skip on everything and check what would be executed, you can activate a preview mode via environment variable like so:

PUBLICATOR_PREVIEW=true publicator <version>

Shell Completion

Publicator stands on the shoulders of Typer, which is a robust CLI library for Python. You can generate TAB completions for common shells such as Bash, ZSH, Fish, and Powershell.

publicator --install-completion <shell>
