//pytho/entrypoints:py_console_script_binary

This rule is to make it easier to generate console_script entry points as per Python specification.

Generate a py_binary target for a particular console_script entry_point from a PyPI package, e.g. for creating an executable pylint target use:

load("@rules_python//python/entry_points:py_console_script_binary.bzl", "py_console_script_binary")

py_console_script_binary(
    name = "pylint",
    pkg = "@pip//pylint",
)

Or for more advanced setups you can also specify extra dependencies and the exact script name you want to call. It is useful for tools like flake8, pylint, pytest, which have plugin discovery methods and discover dependencies from the PyPI packages available in the PYTHONPATH.

load("@rules_python//python/entry_points:py_console_script_binary.bzl", "py_console_script_binary")

py_console_script_binary(
    name = "pylint_with_deps",
    pkg = "@pip//pylint",
    # Because `pylint` has multiple console_scripts available, we have to
    # specify which we want if the name of the target name 'pylint_with_deps'
    # cannot be used to guess the entry_point script.
    script = "pylint",
    deps = [
        # One can add extra dependencies to the entry point.
        # This specifically allows us to add plugins to pylint.
        "@pip//pylint_print",
    ],
)

A specific Python version can be forced by using the generated version-aware wrappers, e.g. to force Python 3.9:

load("@python_versions//3.9:defs.bzl", "py_console_script_binary")

py_console_script_binary(
    name = "yamllint",
    pkg = "@pip//yamllint",
)

Alternatively, the py_console_script_binary.binary_rule arg can be passed the version-bound py_binary symbol, or any other py_binary-compatible rule of your choosing:

load("@python_versions//3.9:defs.bzl", "py_binary")
load("@rules_python//python/entry_points:py_console_script_binary.bzl", "py_console_script_binary")

py_console_script_binary(
    name = "yamllint",
    pkg = "@pip//yamllint:pkg",
    binary_rule = py_binary,
)

Creates an executable (a non-test binary) for console_script entry points.

py_console_script_binary

Generate a py_binary for a console_script entry_point.

PARAMETERS

Name	Description	Default Value
name	str, The name of the resulting target.	none
pkg	target, the package for which to generate the script.	none
entry_points_txt	optional target, the entry_points.txt file to parse for available console_script values. It may be a single file, or a group of files, but must contain a file named entry_points.txt. If not specified, defaults to the dist_info target in the same package as the pkg Label.	None
script	str, The console script name that the py_binary is going to be generated for. Defaults to the normalized name attribute.	None
binary_rule	callable, The rule/macro to use to instantiate the target. It's expected to behave like py_binary. Defaults to @rules_python//python:py_binary.bzl#py_binary.	<function py_binary>
kwargs	Extra parameters forwarded to binary_rule.	none
