zig-zon 0.2.1

a native cpython extension to parse zig object notation strings

Python Zig Zon Parser

A native python extension built with zig to parse zig-object-notation strings into python objects.

On PyPi it is only distributed in source, and built during install. It therefore needs to download the ziglang python package.

Depending on your OS, you may need the python development headers (e.g. python3-dev) installed.

Usage

install from source on pypi:

pip install zig-zon

running:

import zig_zon
parsed = zig_zon.parse('.{.allyourcode = .are_belong_to_us, .asd = 123}')
print(parsed)

or, look at the test file

How it works

The zig build commands produces a python source distribution archive ready for uploading to Pypi. It includes the sources of zig-python-sdist and a custom setup.py that handles the build of the cpython extension.

When you run pip install, the source distribution is downloaded, and since this source distribution depends on the ziglang python package at build time, a zig build command is used to compile the extension.

Developing

as opposed to other solutions for building cpython extensions in zig, i want to develop this using:

zig build

for linking against the local python installation zig-python-sdist runs a python script that imports the cpython headers into zig's build cache, run translate-c on the result and offers a cpython module to import in our zig code. On windows, the extension library is also linked against the python runtime static lib and renamed to a .pyd file for importing.
