[choieastsea]

Overview

This pull request introduces and configures Ruff (Python linter and formatter) for the project. The primary goal is to automate code styling and linting to improve overall code quality, consistency, and developer productivity.

You can check your codes by uv run ruff check, or fix with --fix option.

Key Changes

The Ruff configuration has been added to pyproject.toml with the following key settings:

1. Formatter Configuration ([tool.ruff.format])

• Line Length: A maximum line length of 79 characters is enforced.
• Quote Style: Standardizes string literals to use double quotes (").
• Indentation: Enforces the use of spaces for indentation.
• Docstring Formatting: Code examples within docstrings will now be automatically formatted.

2. Linter Configuration ([tool.ruff.lint])

• Enabled Rules (select): The linter is configured to check for:
  • C: Code complexity (from flake8-comprehensions, mccabe)
  • E: Style guide violations (from pycodestyle)
  • F: Logical errors (from Pyflakes)
  • S: Potential security issues (from flake8-bandit)
  • U: Modern Python syntax suggestions (from pyupgrade)
  • I: Import sorting issues (from isort)
• Ignored Rules (ignore):
  • C901: Ignores "function too complex" warnings, which can be addressed in future refactoring.
  • E501: Ignores "line too long" warnings, as this is handled automatically by the formatter.
• isort Configuration:
  • Adds 2 blank lines after the main import block for better separation.
• pydocstyle Configuration:
  • Enforces the Google style convention for all docstrings.
