rules_ty

Bazel rules for ty, the fast Python type checker by Astral.

Similar to rules_mypy but targeting ty, Bazel 9+, and fixing known pain points:

• No types mapping — rely on gazelle instead
• No per-target cache propagation — ty is fast enough
• No python_version parameter — inferred from the Python toolchain
• Works with any rules_python configuration — no venvs_site_packages requirement

Status

Under development — design phase. No usable rules yet.

• Project kick-off and architectural decisions (#1)
• PoC: validate ty's module resolution in a Bazel sandbox (#2)
• Sphinx / readthedocs documentation (#3)
