refactor: have bzlmod pass platforms to python_register_toolchains (#2884) This is to facilitate eventually allowing overrides to add additional platforms. Instead of the PLATFORMS global being used, the python bzlmod extension passing the mapping directly to python_register_toolchains, then receives back the subset of platforms that had repos defined. That subset is then later used when (re)constructing the list of repo names for the toolchains.
This repository is the home of the core Python rules -- py_library, py_binary, py_test, py_proto_library, and related symbols that provide the basis for Python support in Bazel. It also contains package installation rules for integrating with PyPI and other indices.
Documentation for rules_python is at https://rules-python.readthedocs.io and in the Bazel Build Encyclopedia.
Examples live in the examples directory.
The core rules are stable. Their implementation is subject to Bazel's backward compatibility policy. This repository aims to follow semantic versioning.
The Bazel community maintains this repository. Neither Google nor the Bazel team provides support for the code. However, this repository is part of the test suite used to vet new Bazel releases. See How to contribute page for information on our development workflow.
