The Pylint linter for Python code (https://www.pylint.org/).
Don't use Pylint when running
Arguments to pass directly to Pylint, e.g.
Requirement string for the tool.
--pylint-extra-requirements="['<str>', '<str>', ...]"
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.
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
--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].invalid_lockfile_behavior). See https://github.com/pantsbuild/pants/blob/release_2.10.1rc1/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].invalid_lockfile_behavior = 'ignore'.
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.
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.
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.
If true, Pants will include any relevant config files during runs (
[pylint].config instead if your config is in a non-standard location.
--pylint-source-plugins="[<target_option>, <target_option>, ...]"
An optional list of
python_sources 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
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.
Tip: it's often helpful to define a dedicated 'resolve' via
[python].resolves for your Pylint plugins such as 'pylint-plugins' so that the third-party requirements used by your plugin, like
pylint, do not mix with the rest of your project. Read that option's help message for more info on resolves.
