A Fast Alternative to Pylint R0801

Описание и применение

Arid – быстрый инструмент для обнаружения дублирования кода в Python, заменяющий Pylint R0801 и ускоряющий CI.

Задача

Duplicate code detection (Pylint R0801) is slow and adds unnecessary overhead when only that check is needed.

Результат

Arid is 191–250× faster than Pylint for duplicate-code detection, enabling fast local feedback and structured CI reporting without the overhead of a full linter.

Рабочий процесс

• 1. Install Ruff and Arid (e.g., via uv or pip).
• 2. Run Ruff for general linting: ruff check .
• 3. Run Arid for duplicate detection: arid . or use the GitHub Action sponge-b0b/[email protected].
• 4. Configure Arid to ignore comments, docstrings, imports, or function signatures if desired.
• 5. In CI, use Arid’s SARIF or JSON output for automated analysis and baseline management.
• 6. For mature codebases, record existing duplicates as baseline and enforce only new duplicates.

Доказательства

Running serially, the results were: Requests — 191.19x faster, Pydantic — 219.06x faster, Polaris — 249.68x faster
