Lenses for the Masses: Introducing Goggles
summary
The talk presents Goggles, a Scala macro built on the Monocle optics library that creates a compiler-checked mini-language for constructing, composing and applying lenses/optics. It explains the usability problem with existing optic implementations (either very powerful but hard to learn, or simple but limited) and shows how Goggles uses Scala macros and flexible syntax to offer a concise, familiar interface with informative compiler errors; the talk also discusses the macro implementation details.
