Death to boilerplate with Scala meta
summary
Scala.meta macros are used to eliminate repetitive boilerplate by generating concrete Scala code with quasiquotes for building and pattern‑matching ASTs. They can create companion objects, implicit helpers, and methods with varying arities (for example a Show/string representation for case classes); macros must live in a separate compilation unit, require sbt clean && compile to see generated code, and currently work on Scala 2.11 and 2.12 — demonstrated in the Hamster project.
