Abstract

En 中文
Functional reactive programming (FRP) is a programming paradigm for implementing reactive systems, i.e. programs that continuously interact with their environments. While FRP allows for a functional, high-level programming style, FRP programs are prone to undesirable operational behaviours such as space leaks. To ensure favourable operational properties of FRP programs, modal type systems have been introduced, which among other things make it impossible to write FRP programs with implicit space leaks. In a recent development, several modal FRP languages have been introduced that are able to accommodate asynchronous events and behaviours motivated by the goal to use such languages for GUI programming. This paper explores the suitability of one such asynchronous modal FRP language called Async Rattus for GUI programming in practice. To this end, we have implemented a mild extension of the Async Rattus language and used it to implement a small GUI framework. We demonstrate the language and its GUI framework by a number of case studies.
