Representing user interfaces as effects in the capability-passing style gives a simple framework for creating UIs. In this talk I'll explain how capability-passing works and use it to implement a simple terminal user interface library. We'll then discuss what general principles we can take from this, that can apply to any problem.

Scala Native is great! It creates small and fast binaries, and can access all operating systems features. This workshop will introduce working with Scala Native by building a terminal based application. We'll learn how to setup and build Native code, call into with system libraries, and use the archaic but powerful features of the terminal.
