pylint
The Pylint linter for Python code (https://www.pylint.org/).
Backend: pants.backend.python.lint.pylint
Config section: [pylint]
Basic options
False
If true, don't use Pylint when running ./pants lint
.
[]
Arguments to pass directly to Pylint, e.g. --pylint-args='--ignore=foo.py,bar.py --disable=C0330,W0311'
.
True
If true, export a virtual environment with Pylint when running ./pants export
.
This can be useful, for example, with IDE integrations to point your editor to the tool's binary.
Advanced options
pylint>=2.13.0,<2.15
Requirement string for the tool.
extra_requirements
extra_requirements
--pylint-extra-requirements="['<str>', '<str>', ...]"
PANTS_PYLINT_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.
<default>
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].invalid_lockfile_behavior
). See https://github.com/pantsbuild/pants/blob/release_2.14.2rc2/src/python/pants/backend/python/lint/pylint/pylint.lock 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 and supply-chain security.
To use a custom lockfile, set this option to a file path relative to the build root, then run ./pants generate-lockfiles --resolve=pylint
.
Alternatively, you can set this option to the path to a custom lockfile using pip's requirements.txt-style, ideally with --hash
. Set [python].invalid_lockfile_behavior = 'ignore'
so that Pants does not complain about missing lockfile headers.
pylint
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.
None
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.
None
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.
True
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
source_plugins
--pylint-source-plugins="[<target_option>, <target_option>, ...]"
PANTS_PYLINT_SOURCE_PLUGINS
[]
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 [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.
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.
