a3s-code 4.2.2

A3S Code Python SDK — pure-Python bootstrap that fetches the native wheel from GitHub Releases

a3s-code (Python bootstrap)

pip install a3s-code ships this small pure-Python package. On first import a3s_code it downloads the native extension matching your interpreter and platform from the project's GitHub Releases, verifies the wheel's sha256 against the release manifest, extracts the compiled extension into a per-user cache, and exposes the normal a3s_code API.

Subsequent imports use the cached extension. Cache lives under ~/.cache/a3s-code/<version>/ (or $XDG_CACHE_HOME/a3s-code/<version>/).

Why

PyPI imposes a default 10 GB per-project storage cap. A Rust SDK with ~17 MB native wheels per Python × platform tripped that limit. GitHub Releases is the canonical wheel host; this bootstrap keeps pip install a3s-code working without dragging the native wheels back through PyPI.

Supported platforms

• macOS arm64 (Apple Silicon)
• Linux x86_64 (glibc 2.28+)
• Windows x86_64

CPython 3.10, 3.11, 3.12, 3.13.

Environment overrides

Variable	Effect
A3S_CODE_CACHE_DIR	Cache root (defaults to $XDG_CACHE_HOME/a3s-code or ~/.cache/a3s-code)
A3S_CODE_RELEASES_BASE_URL	Override the release base URL — useful for air-gapped mirrors
A3S_CODE_SKIP_HASH_CHECK	1 skips sha256 verification (do not use in production)

Manual install

If you do not want the bootstrap to phone home, install the native wheel directly:
