SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers understand and utilize Cangjie language's advanced features for metaprogramming, including how to control integer overflow behavior and dynamically inspect and manipulate code elements at runtime.

Core Features & Use Cases

  • Integer Overflow Control: Manage arithmetic overflow with @OverflowThrowing, @OverflowWrapping, and @OverflowSaturating annotations.
  • Custom Annotations: Define and apply custom annotations to classes, members, and parameters using @Annotation.
  • Runtime Reflection: Inspect types, variables, properties, and functions using the TypeInfo class for dynamic code analysis and manipulation.
  • Use Case: Debugging complex arithmetic operations by precisely controlling overflow behavior, or building a plugin system that discovers and utilizes custom annotations at runtime.

Quick Start

Show me how to use the @OverflowThrowing annotation on a function that performs addition.
