LanguageProject Introduction
Summary
Pyre-check is a powerful open-source static analysis tool for Python, designed to provide rapid type checking and enhance code quality in large codebases.
Problem Solved
Dynamically typed languages like Python can have runtime errors due to type mismatches. Pyre-check helps catch these errors during development, before code is executed, reducing bugs and facilitating safer refactoring.
Core Features
Fast Incremental Checking
Analyzes code changes quickly, providing rapid feedback in editors and CI.
IDE Integration
Seamlessly integrates with popular IDEs like VS Code and PyCharm for real-time type diagnostics.
Support for Type Stubs (.pyi)
Leverages type stubs for third-party libraries, enabling checking of code that interacts with dynamically typed dependencies.
