lintro 0.37.7

A unified CLI tool for code formatting, linting, and quality assurance

Lintro

A comprehensive CLI tool that unifies various code formatting, linting, and quality assurance tools under a single command-line interface.

🚀 Quick Start

pip install lintro          # Install
lintro check .              # Find issues
lintro format .             # Fix issues
lintro check --output-format grid   # Beautiful output

✨ Why Lintro?

• 🎯 Unified Interface - One command for all your linting and formatting tools
• 📊 Consistent Output - Beautiful, standardized output formats across all tools
• 🔧 Auto-fixing - Automatically fix issues where possible
• 🐳 Docker Ready - Run in isolated containers for consistent environments
• 📈 Rich Reporting - Multiple formats: grid, JSON, HTML, CSV, Markdown
• ⚡ Fast - Optimized parallel execution

🔌 Works With Your Existing Configs

Lintro respects your native tool configurations. If you have a .prettierrc, pyproject.toml [tool.ruff], or .yamllint, Lintro uses them automatically - no migration required.

• Native configs are detected - Your existing .prettierrc, .eslintrc, etc. work as-is
• Enforce settings override consistently - Set line_length: 88 once, applied everywhere
• Fallback defaults when needed - Tools without native configs use sensible defaults

See the Configuration Guide for details on the 4-tier config system.
