Elixir AST Transformation for Cleaner Code

Writing powerful domain-specific languages in Elixir often leads to complex macros and excessive code generation. By understanding how to directly manipulate the Abstract Syntax Tree, you can write cleaner, more maintainable code that performs beautifully. This text-based course guides you through the mechanics of AST traversal, enabling you to optimize your Elixir applications from the inside out. You will transition from writing basic macros to confidently walking and rewriting AST structures for custom HTML DSLs. By mastering these core compilation concepts, you will significantly reduce generated code size while keeping your codebase readable and elegant. What you'll learn: - Understand the foundational structure of the Elixir Abstract Syntax Tree - Traverse and inspect AST nodes using pattern matching and recursion - Build custom HTML DSLs with minimal macro overhead - Apply AST transformation techniques to optimize code generation - Implement modern Elixir development practices including proper type specs - Debug complex macro expansions using built-in compilation tools This course begins with essential terminology, explaining exactly how Elixir represents code as data before moving into hands-on AST manipulation. You will progress from basic quote and unquote operations to building a fully functional, lightweight HTML DSL. This course is designed for intermediate Elixir developers who want to deepen their understanding of metaprogramming, with no prior compiler or AST experience required. Start mastering Elixir metaprogramming today to write cleaner, more efficient DSLs.
