Relevant Rules

Description

Currently I am using bazel and gazelle to manage a mono repo with multiple python projects.

Some of them using python 3.10 and others are using python 3.11.

When using gazelle with rules_python, I need to manually append python_version=3.11 to generated py_test rule.

For example

# generated by gazelle

py_test(
    name = "test_module_a",
    srcs = ["module-a/tests/test_module_a.py"],
    python_version = "3.11", # manually edit line
    deps = [
        "//module-a/src/module_a"
    ],
)

Describe the solution you'd like

We should have a new directive such as gazelle:python_version to allow user to override python_version attribute in generated py_test and py_binary rules.

Describe alternatives you've considered

Gemini also suggested to use a build_arg to override default generated rules but it doesn't work.
