pj-py

Spawn and ship Python projects from templates.

pip install pj-py
pj-py init my-lib   # create
# ... code, commit, push ...
pj-py ship           # release

Commands

init — create a project

pj-py init my-lib -d "Does one thing well"

Spawns a new GitHub repo from 1iis/py (the reference Python template), clones it locally, renames my_package to your project name, installs dependencies, and makes the initial commit.

from pj_py import init

p = init("my-lib")
# → Project(owner="1iis", repo="my-lib", path=Path("my-lib"))

ship — release a new version

pj-py ship "### Added\n\n- Feature X"
pj-py ship                    # auto-generates boilerplate

Non-interactive, one-call release: bumps the version via fastship, writes the changelog entry, commits and pushes, creates a GitHub release, and uploads to PyPI.

from pj_py import ship

v = ship()                     # patch bump
v = ship("minor")              # minor bump
v = ship("major")              # major bump
# → "0.0.3"

Requires .pypirc configured for PyPI uploads.

Prerequisites

• Python 3.10+
• uv (install)
• git
• GitHub token with repo scope for init — set GITHUB_TOKEN
• .pypirc with PyPI token for ship
• fastship

Architecture

1iis/py    — Language template (hatchling, ruff, uv, fastship)
    ↓
pj-py      — init() + ship() from templates
 ↓
pj         — (future) Language-agnostic wrapper

Design

• Pure library — all UX (colors, progress bars, interactive prompts) lives in a higher-level wrapper
• Raise, don't print — errors are exceptions (PjPyError, AuthError, ShipError)
• Blocking — init() and ship() return only when the project is fully ready
• Single responsibility — knows Python templates and Python packaging. That's it.
• Lean — delegates to fastship for version bumping and PyPI upload, to ghapi for GitHub API, to uv for dependency management
