isage-pypi-publisher 0.2.1.0

Python bytecode compiler and PyPI publishing toolkit for monorepos

sage-pypi-publisher

A tiny toolkit to compile Python packages to bytecode, build wheels, and publish to PyPI/TestPyPI. Extracted from SAGE's internal sage-dev tooling and made standalone.

Features

• Copy a package tree and compile .py → .pyc (keeps __init__.py and _version.py).
• Auto-adjust pyproject.toml / MANIFEST.in to include compiled artifacts and binary extensions.
• Build wheels with python -m build.
• 🚀 NEW: Smart --for-pypi mode - one command for perfect PyPI publishing!
• NEW: Universal wheel support - one wheel works on all Python 3.x versions!
• NEW: Source distribution (sdist) support - users can install from source on any version
• Upload via twine (with --dry-run by default).
• Simple Typer-based CLI.

Solving the Multi-Version Problem

Problem: Your package declares support for Python 3.8-3.12, but you only upload a wheel for Python 3.11. Users on other versions can't install it!

Solution: sage-pypi-publisher now uses Smart Mode by default 🎯

# That's it! No extra flags needed - smart mode is automatic
sage-pypi-publisher build . --upload --no-dry-run

What happens automatically:

• ✅ Pure Python packages: Builds universal wheel (py3-none-any) that works on ALL Python 3.x versions!
• ✅ Packages with C extensions: Builds for current Python + provides source code for others
• ✅ Always includes source distribution (sdist) as fallback
• ✅ No need to build wheels for each Python version separately!

Why this works:

• Universal wheel (py3-none-any): One file works on Python 3.8, 3.9, 3.10, 3.11, 3.12, and future versions!
• Source distribution: If universal wheel doesn't work, users can compile from source
• Zero configuration: Works perfectly out of the box!

Installation

pip install .
# or
pip install sage-pypi-publisher

CLI

Quick Start

🎯 Simplest Usage (Smart Mode - Default!)

# Just build - automatically chooses best strategy!
sage-pypi-publisher build .

# Build and upload to TestPyPI
sage-pypi-publisher build . --upload -r testpypi

# Build and upload to PyPI (production)
sage-pypi-publisher build . --upload --no-dry-run -r pypi

What Smart Mode Does (Automatically):

• 🔍 Detects if your package is pure Python or has C extensions
• 📦 Pure Python → builds universal wheel (works on ALL Python 3.x!)
• 🔧 C extensions → builds for current Python version
• 📚 Always includes source distribution (sdist)
• ✅ Perfect for packages declaring Python 3.8+ support!

Manual Control (Advanced):

# Disable smart mode (old behavior - current Python only)
sage-pypi-publisher build . --no-for-pypi

# Force universal wheel
sage-pypi-publisher build . --universal

# Force specific mode
sage-pypi-publisher build . --mode public

All Commands

sage-pypi-publisher --help

# 🎯 Simplest: Build with smart mode (default!)
sage-pypi-publisher build .

# Build and upload to PyPI
sage-pypi-publisher build . --upload --no-dry-run

# Compile only (bytecode mode by default)
sage-pypi-publisher compile /path/to/pkg -o /tmp/out

# Compile in public mode (keep source)
sage-pypi-publisher compile /path/to/pkg -o /tmp/out --mode public

# Disable smart mode (old behavior)
sage-pypi-publisher build /path/to/pkg --no-for-pypi

# Force universal wheel (manual override)
sage-pypi-publisher build /path/to/pkg --universal

# Force manylinux build for C/C++ extensions
sage-pypi-publisher build /path/to/pkg --force-manylinux

# Upload an existing wheel
sage-pypi-publisher upload dist/yourpkg-0.1.0-py3-none-any.whl -r pypi --no-dry-run

Build Modes

• --mode private (default): Compile to .pyc bytecode (保密模式 - protects source code)
• --mode public: Keep .py source files (公开模式 - open source)
• Aliases: bytecode = private, source = public

Python API

Basic Usage

fromPyPI Publishing Options

**Smart Mode (Default) 🎯**
- **Enabled automatically** - no flags needed!
- Pure Python → universal wheel + sdist
- C extensions → current Python wheel + sdist
- Use `--no-for-pypi` to disable

**Manual Override:**
- **`--universal`**: Force universal wheel (py3-none-any) - only works for pure Python packages
- **`--sdist`**: Add source distribution (.tar.gz)
- **`--no-for-pypi`**: Disable smart mode, build for current Python only

**Why NOT build wheels for each Python version?**

You might wonder: "Why not build cp38, cp39, cp310, cp311, cp312 wheels separately?"

**Technical limitation**: To build a wheel for Python 3.10, you need Python 3.10 installed and running. You can't build a true Python 3.10 wheel from Python 3.11 environment.

**Better solution**: 
- Pure Python packages → Use universal wheel (py3-none-any) - ONE wheel for ALL versions!
- C extensions → Provide source distribution (sdist) so users can compile for their Python version
- For production C extensions with multiple versions → Use `cibuildwheel` in CI/CD
wheeUniversal Wheel (Recommended for Pure Python)
```python
from pathlib import Path
from pypi_publisher.compiler import BytecodeCompiler

# For pure Python packages
compiler = BytecodeCompiler(Path("/path/to/pkg"), mode="public")
compiled = compiler.compile_package()

# Build universal wheel (works on ALL Python 3.x)
universal_wheel = compiler.build_universal_wheel(compiled)

# Build source distribution
sdist = compiler.build_sdist(compiled)

# Upload both
for artifact in [universal_wheel, sdist]:
    compiler.upload_wheel(artiface_package()

# Build source distribution
sdist = compiler.build_sdist(compiled)
compiler.upload_wheel(sdist, repository="pypi", dry_run=False)

Git Hooks

sage-pypi-publisher provides intelligent git hooks to simplify version management and PyPI publishing.

Installation

sage-pypi-publisher install-hooks .

Features

• Auto-detection: Detects version changes in pyproject.toml on push.
• Interactive Update: Prompts to update version if forgotten.
• Auto-Publish: Builds and uploads to PyPI automatically upon confirmation.
• Smart Build: Detects C/C++ extensions for manylinux wheels.

Notes

• Requires python -m build and twine available.
• No backward compatibility with sage-dev CLI; PyPI commands have been removed from SAGE.
• Designed to be monorepo-friendly but works with any package path that contains pyproject.toml.
