Macros for Mortals

Presentation

Since their introduction in 2.10, Macros have veritably taken Scala by storm. They pop up everywhere, often providing elegant syntax extensions for Scala libraries – note the prevalence of “sql” string interpolation macros, for example.

Many developers, however, are scared and confused by Macros – rightly so. Many examples of Macros require deep knowledge of the Scala AST, internals and oddities. But hope exists: newer features like quasiquotes make it ridiculously easy to write powerful Macros with code templating.

In this talk, we’ll demystify just how Macros work and are constructed, walking through many of the different “types” of Macros that Scala supports. A final focus will be given to the use of the newer Quasiquotes and Annotations features as a way of quickly constructing powerful new code features in your own Scala code.
