Does it support AST manipulation?

Absolutely, it provides guidance on inspecting and transforming various Abstract Syntax Tree (AST) node types like Call, NumberLiteral, and StringLiteral.

What are Crystal macros used for?

Crystal macros are used for compile-time metaprogramming, allowing you to generate code dynamically, create DSLs, and perform computations before the program is actually compiled.

Can this skill help with DSL design?

Yes, it specializes in using macro methods and block yielding to create expressive, domain-specific languages within Crystal applications.

How does it handle platform-specific code?

It uses compile-time conditionals and platform flags to generate specific code paths for different operating systems like Windows, Linux, or macOS.

API Development

Automates code generation and builds domain-specific languages (DSLs) using Crystal's powerful compile-time macro system.

About

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.
