GPU project providing WebGPU access across as wide of the Python ecosystem as possible: - gpu-api: Pure Python unified API abstraction - gpu-dawn: Dawn (Google) backend for native platforms - gpu-wgpu: wgpu-native (Rust) backend for native platforms - gpu-pyodide: Dawn Emscripten backend for browser/Pyodide - gpu-canvas: Windowing system integration - gpu-wesl: WESL for extended WGSL support Platform support: Linux/Windows/macOS (x64/ARM64), Pyodide/WASM Python versions: 3.10-3.14 including free-threaded builds Includes: - Package skeletons with nanobind/scikit-build-core setup - CI/CD workflows for wheel building and testing - Development tooling (uv, ruff, basedpyright, duties.py) - Environment setup scripts and prerequisites documentation - CLAUDE.md with development workflow instructions
- test.yml: Build native wheels within each test job for the specific Python version being tested (native wheels are ABI-specific) - Remove build-frontend = "build[uv]" from cibuildwheel configs (requires pre-installed uv in containers which adds complexity) - Add periods to docstrings in C++ source so generated stubs pass linting
- Use macos-15-intel (Intel) for x86_64 builds instead of cross-compiling on ARM64
- Revert CMake cross-compile detection (not needed with native runners)
- Use string format for repair-wheel-command to fix {package} expansion
- Fix gpu-pyodide cibuildwheel config (build selector goes in global section)
- Remove build_dawn_pyodide job (gpu-pyodide handles Pyodide builds)
- Upgrade cibuildwheel from v2.22 to v3.3.1 for {package} placeholder support
- Remove unused pyodide config from gpu-dawn/pyproject.toml
- Update dev dependency to cibuildwheel>=3.3.1 (Python 3.11+)
- Build sdists first, then build wheels from those sdists - Add platform-specific repair-wheel-command configs: - Linux: auditwheel repair - macOS: delocate-wheel - Windows: delvewheel repair (with before-build pip install) - Set macOS deployment targets: 10.15 for x86_64, 11.0 for arm64 - Consolidate workflow from 11 jobs to 7 jobs
