Using Bzlmod with Bazel 6

NOTE: bzlmod support is still beta. APIs subject to change.

Add to your MODULE.bazel file:

bazel_dep(name = "rules_python", version = "0.33.0")

pip = use_extension("@rules_python//python/extensions:pip.bzl", "pip")

pip.parse(
    hub_name = "pip",
    python_version = "3.11",
    requirements_lock = "//:requirements_lock.txt",
)

use_repo(pip, "pip")

Using WORKSPACE

Paste this snippet into your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
    name = "rules_python",
    sha256 = "dc6e2756130fafb90273587003659cadd1a2dfef3f6464c227794cdc01ebf70e",
    strip_prefix = "rules_python-0.33.0",
    url = "https://github.com/bazelbuild/rules_python/releases/download/0.33.0/rules_python-0.33.0.tar.gz",
)

load("@rules_python//python:repositories.bzl", "py_repositories")

py_repositories()

Gazelle plugin

Paste this snippet into your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
http_archive(
    name = "rules_python_gazelle_plugin",
    sha256 = "dc6e2756130fafb90273587003659cadd1a2dfef3f6464c227794cdc01ebf70e",
    strip_prefix = "rules_python-0.33.0/gazelle",

# To compile the rules_python gazelle extension from source,
# we must fetch some third-party go dependencies that it uses.

load("@rules_python_gazelle_plugin//:deps.bzl", _py_gazelle_deps = "gazelle_deps")

What's Changed

🎉 0.33.0 of rules_python and the gazelle plugin has just been tagged, notable changes/fixes/additions:

  • gazelle plugin is now using tree-sitter instead of Python to parse python files, which makes it 3 times faster on larger monorepos and it does not require a python interpreter anymore. There is a known issue of the plugin being tricky to cross-compile, so please leave comments there if you are seeing issues.
  • The dependence on the system having a Python interpreter can now be avoided if using a hermetic toolchain. This can be enabled with bootstrap_impl config setting.
  • The MODULE.bazel.lock file is now the same irrespective of the host platform that rules_python is being used on. This required to remove host-platform specific references in @pythons_hub//:interpreters.bzl, so if you want to use a host python in a repository rule context, use @python_{version}_host//:python.
  • The python files can now be compiled to .pyc during the bazel build phase, enable this with @rules_python//python/config_settings:precompile=enabled config setting, more info in the docs.
  • whl_filegroup can now be used to extract files from a whl target. This is useful in cases where one wants to use e.g. numpy headers or similar. The benefit of this is that users don’t need to modify the pip.parse whl distributions and can have better performance (no need to refetch the pip packages when the desired file list changes) and ergonomics through build-time rules.
  • experimental_index_url flag in pip.parse now enables using the whl filenames to derive the target platform config settings, so you can finally get the right wheel for the right target platform. It is best to use this feature together with requirements_by_platform (also added in 0.33.0) to specify requirements files per (os, arch) explicitly. We now also do not ignore yanked packages which mirrors the behaviour of uv more closely. The users have a few config settings that they can use to change the behaviour (preference of universal2 wheels on osx, preference of musllinux and the libc version on linux, disabling sdist). The config settings are documented here.
