From 4faf1c4ff7471590907b9aa9287c9eaef77c14f8 Mon Sep 17 00:00:00 2001 From: Neroued Date: Tue, 17 Mar 2026 00:19:44 +0800 Subject: [PATCH 01/28] feat: add Python bindings, CI/CD pipeline, and cross-platform wheel builds - pybind11 bindings exposing Rgb, VectorizerConfig, VectorizerResult, vectorize() - Full docstrings and type stubs (_core.pyi) for IDE support - VectorizerResult.save() convenience method - scikit-build-core + setuptools-scm for packaging and dynamic versioning - GitHub Actions CI: C++ builds (Linux/macOS/Windows), Python tests (3.10-3.13), clang-format check on PRs - cibuildwheel: Linux x86_64/aarch64, macOS x86_64/arm64, Windows AMD64 - Staged publishing: TestPyPI for pre-releases, PyPI for stable tags - 22 pytest cases covering all public API surface
