Crystal Macros & Metaprogramming
Automates code generation and builds domain-specific languages (DSLs) using Crystal's powerful compile-time macro system.
This skill empowers developers to leverage Crystal's unique compile-time execution capabilities to eliminate boilerplate and build sophisticated abstractions. It provides deep expertise in manipulating Abstract Syntax Trees (AST), implementing type-safe configurations, and creating custom DSLs that execute during compilation. Whether you are generating serialization logic, building ORM-like features, or handling platform-specific code, this skill ensures your macros are efficient, readable, and maintainable.
