Zig PyPI distribution

This repository contains the script used to repackage the releases of the Zig programming language as Python binary wheels. This document is intended for maintainers; see the package README for rationale and usage instructions.

The repackaged artifacts are published as the ziglang PyPI package.

Preparation

The script requires Python 3.5 or later.

Install the dependencies:

pip install wheel twine libarchive-c

The libarchive-c Python library requires the native libarchive library to be available.

Building wheels

Run the repackaging script:

python make_wheels.py --help
usage: make_wheels.py [-h] [--version VERSION] [--suffix SUFFIX] [--outdir OUTDIR]
                                                  [--platform {x86_64-windows,x86_64-macos,aarch64-macos,i386-linux,x86-linux,x86_64-linux,aarch64-linux,armv7a-linux}]

Repackage official Zig downloads as Python wheels

options:
  -h, --help            show this help message and exit
  --version VERSION     version to package, use `latest` for latest release, `master` for nightly build
  --suffix SUFFIX       wheel version suffix
  --outdir OUTDIR       target directory
  --platform {x86_64-windows,x86_64-macos,aarch64-macos,i386-linux,x86-linux,x86_64-linux,aarch64-linux,armv7a-linux}
                        platform to build for, can be repeated

This command will download the Zig release archives for every supported platform and convert them to binary wheels, which are placed under dist/. The Zig version and platforms can be passed as arguments.

The process of converting release archives to binary wheels is deterministic, and the output of the script should be bit-for-bit identical regardless of the environment and platform it runs under. To this end, it prints the SHA256 hashes of inputs and outputs; the hashes of the inputs will match the ones on the Zig downloads page, and the hashes of the outputs will match the ones on the PyPI downloads page.

Uploading wheels

Run the publishing utility:

twine dist/*

This command will upload the binary wheels built in the previous step to PyPI.
