pylint

skip

Don't use Pylint when running ./pants lint

args

Arguments to pass directly to Pylint, e.g. --pylint-args="--ignore=foo.py,bar.py --disable=C0330,W0311"

version

Requirement string for the tool.

extra_requirements

Any additional requirement strings to use with the tool. This is useful if the tool allows you to install plugins or if you need to constrain a dependency to a certain version.

lockfile

Path to a lockfile used for installing the tool.

Set to the string <default> to use a lockfile provided by Pants, so long as you have not changed the --version and --extra-requirements options, and the tool's interpreter constraints are compatible with the default. Pants will error or warn if the lockfile is not compatible (controlled by [python-setup].invalid_lockfile_behavior). See https://github.com/pantsbuild/pants/blob/release_2.7.1rc1/src/python/pants/backend/python/lint/pylint/lockfile.txt for the default lockfile contents.

Set to the string <none> to opt out of using a lockfile. We do not recommend this, though, as lockfiles are essential for reproducible builds.

To use a custom lockfile, set this option to a file path relative to the build root, then run ./pants generate-lockfiles --resolve=pylint.

Lockfile generation currently does not wire up the [python-repos] options. If lockfile generation fails, you can manually generate a lockfile, such as by using pip-compile or pip freeze. Set this option to the path to your manually generated lockfile. When manually maintaining lockfiles, set [python-setup].invalid_lockfile_behavior = 'ignore'.

console_script

The console script for the tool. Using this option is generally preferable to (and mutually exclusive with) specifying an --entry-point since console script names have a higher expectation of staying stable across releases of the tool. Usually, you will not want to change this from the default.

entry_point

The entry point for the tool. Generally you only want to use this option if the tool does not offer a --console-script (which this option is mutually exclusive with). Usually, you will not want to change this from the default.

config

Path to a config file understood by Pylint (http://pylint.pycqa.org/en/latest/user_guide/run.html#command-line-options).

Setting this option will disable [pylint].config_discovery. Use this option if the config is located in a non-standard location.

config_discovery

If true, Pants will include any relevant config files during runs (.pylintrc, pylintrc, pyproject.toml, and setup.cfg).

Use [pylint].config instead if your config is in a non-standard location.

source_plugins

An optional list of python_library target addresses to load first-party plugins.

You must set the plugin's parent directory as a source root. For example, if your plugin is at build-support/pylint/custom_plugin.py, add 'build-support/pylint' to [source].root_patterns in pants.toml. This is necessary for Pants to know how to tell Pylint to discover your plugin. See Source roots

You must also set load-plugins=$module_name in your Pylint config file.

While your plugin's code can depend on other first-party code and third-party requirements, all first-party dependencies of the plugin must live in the same directory or a subdirectory.

To instead load third-party plugins, set the option [pylint].extra_requirements and set the load-plugins option in your Pylint config.
