wasmpy-build 0.3.1

WebAssembly build tool for CPython C extensions

wasmpy-build

This tool can compile CPython C extension files, such as the ones created by Cython, to WebAssembly so that the extensions are platform independent.

This project contains modified CPython header files as well as a build script to ease the creation of .wasm extension files.

Currently this project only supports CPython 3.8, 3.9, 3.10 and 3.11 but I'm hoping to add support for older and future versions.

The project will automatically download wasi-sdk on first use.
