fastship 0.0.3

Local-first release CLI tools: ship_bump, ship_pypi, ship_release_gh

fastship

Tiny, local-first release tools for modern Python projects.

fastship gives you the same workflow feel as the nbdev nbdev_bump_version, release_pypi, and release_gh commands — but for plain (non-notebook) Python projects.

Install

pip install fastship

Quick start

Create a new project:

ship_new my-project
cd my-project
python -m venv .venv && . .venv/bin/activate
pip install -e .[dev]

This creates a complete project with pyproject.toml, __version__, LICENSE, README, and everything wired for fastship.

Commands

ship_bump

Bump a version part (0=major, 1=minor, 2=patch):

ship_bump --part 2
ship_bump --part 1
ship_bump --part 0

Decrement instead:

ship_bump --part 2 --unbump

ship_pypi

Build + upload to PyPI:

ship_pypi

Upload to a named repository in ~/.pypirc (e.g. testpypi):

ship_pypi --repository testpypi

Quiet mode:

ship_pypi --quiet

ship_release_gh

This is an interactive helper:

1. Creates/updates CHANGELOG.md from closed GitHub issues since your last GitHub release
2. Opens your $EDITOR (defaults to nano) so you can edit the changelog
3. Prompts you to confirm
4. Runs git commit -am release, git push
5. Creates a GitHub release tagged with your current __version__

ship_release_gh

GitHub token setup

ship_release_gh looks for a token in this order:

1. FASTSHIP_TOKEN
2. a ./token file in your repo root
3. GITHUB_TOKEN

The token must have permission to create releases (typically repo scope for classic PATs, or appropriate fine-grained permissions).

Notes

• ship_pypi does not bump your version for you — keep it explicit and boring.
• ship_release_gh requires that your project has a git origin remote pointing at GitHub (or use --repo OWNER/REPO).

Existing projects

To add fastship to an existing project:

1) Put your version in __init__.py

In your package's main __init__.py:

__version__ = "0.0.1"

2) Configure pyproject.toml

[project]
name = "my-project"
dynamic = ["version"]

[tool.setuptools.dynamic]
version = { attr = "my_project.__version__" }

Keep __version__ = "x.y.z" as a simple literal (don't compute it). ship_bump will rewrite this line near the top of the file to keep builds happy.

3) Optional: specify branch

Fastship infers your package name from [project].name (changing - to _). To override the release branch:

[tool.fastship]
branch = "main"  # defaults to current git branch
