This example demostrates how to use rules_python and gazelle with bzlmod enabled. Bzlmod, the new external dependency subsystem, does not directly work with repo definitions. Instead, it builds a dependency graph from modules, runs extensions on top of the graph, and defines repos accordingly.

Gazelle is setup with the rules_python extension, so that targets like py_library and py_binary can be automatically created just by running:

$ bazel run //:gazelle update

The are other targets that allow you to update the gazelle dependency management when you update the requirements.in file. See:

bazel run //:gazelle_python_manifest.update

For more information on the behavior of the rules_python gazelle extension, see the README.md file in the /gazelle folder.

This example uses a MODULE.bazel file that configures the bzlmod dependency management. See comments in the MODULE.bazel and BUILD.bazel files for more information.
