Writing DSL for DSL: Catch Code as It’s Born with TracePoint

JA

Let’s dive into an unconventional use of Ruby’s TracePoint API, not for performance profiling, but for runtime introspection in metaprogramming-heavy Ruby code.

We’ll focus on real-world use case of writing DSLs for use with existing DSLs, exploring how TracePoint enables us to untangle messy results of metaprogramming techniques and do things like dynamic linking logic to DSL-generated methods.

Expect a blend of advanced Ruby techniques, practical insights, and a fresh perspective on a lesser-known Ruby API.
