Does it support conditional compilation?

Absolutely. It covers using the flag? macro to compile different code paths based on target platform, environment variables, or custom feature flags.

Can I use it to automate serialization?

Yes, one of its primary use cases is generating methods for JSON, YAML, or database serialization based on class instance variables at compile time.

Can this skill help build a custom DSL?

Yes, it provides patterns for using macro methods and blocks to build expressive, domain-specific languages within your Crystal applications.

What are Crystal macros used for?

Crystal macros are used for metaprogramming—writing code that generates more code at compile time. This is ideal for reducing boilerplate, creating DSLs, and performing compile-time checks.

How does it handle AST manipulation?

The skill provides guidance on receiving AST nodes as arguments, inspecting their types, and transforming them into valid Crystal code before the final binary is built.

開発者ツール

Implements advanced compile-time metaprogramming in Crystal for automated code generation and custom DSL creation.

概要

The Crystal Macros skill empowers Claude Code to master the Crystal language's powerful compile-time execution system. It provides comprehensive patterns for building domain-specific languages (DSLs), reducing boilerplate through automated method generation, and performing complex Abstract Syntax Tree (AST) manipulations. By leveraging this skill, developers can implement type-safe abstractions, compile-time validations, and sophisticated introspection tools that execute during the compilation phase, resulting in more performant and maintainable codebases.
