🐞 bug report

Affected Rule

python/private/local_runtime_repo.bzl

Is this a regression?

No

Description

When using a local toolchain on Windows as per https://rules-python.readthedocs.io/en/latest/toolchains.html#local-toolchain,
the define_local_runtime_toolchain.impl.interpreter_path is not escaping the backward slashes, making bazel fail with invalid escape sequence.

If I set:

local_runtime_repo(
    name = "local_python3",
    on_failure = "fail",
    interpreter_path = "python"
    # or interpreter_path = "C:\\path\\to\\python.exe"
)

I get a

# Generated by python/private/local_runtime_repo.bzl

load()

define_local_runtime_toolchain_impl(
    interpreter_path = "C:\path\to\python.exe" # expected: either "\\" or "/"
)
