pylint-plugin-utils

What it is and what it does

pylint-plugin-utils is a toolkit for developers building custom Pylint plugins. Rather than being a plugin itself, it provides reusable utilities and helpers that abstract away common patterns and boilerplate needed when extending Pylint's linting capabilities. The package is used as a foundation by established plugins like pylint-django and pylint-celery, making it a reference implementation for plugin development patterns.

The package requires Pylint as its sole runtime dependency and supports Python 3.9 through 3.13. It is actively maintained and marked production-stable, with a long history dating back to 2013. Installation is straightforward with no compiled dependencies or system-level requirements.

Use it for:

• Building a custom Pylint plugin to enforce domain-specific linting rules in your codebase
• Extending Pylint with framework-specific checks (similar to how pylint-django adds Django support)
• Reducing boilerplate when writing multiple related Pylint plugins
• Learning Pylint plugin architecture by studying an established utilities library

Provides utilities and helper functions for building Pylint plugins, abstracting common patterns used by plugins like pylint-django and pylint-celery.

Yes, if you are writing a Pylint plugin. It is actively maintained, has no known vulnerabilities, and provides a stable foundation used by established plugins. The GPL v2+ license requires your plugin code to be GPL-compatible. If you are only using Pylint as an end user, you do not need this package directly.

Quickstart

pip install pylint-plugin-utils

from pylint_plugin_utils import BaseChecker
# Use utilities in your custom plugin implementation

Requires Pylint to be installed; intended for plugin developers, not end-user linting.

Verify before relying

• What specific utilities and helper functions are included in the API surface
• Whether this package provides base classes, decorators, or other plugin patterns
• Compatibility guarantees with different Pylint versions
