Gregory Cooper


I am the developer of FrTime, an extension of Racket with first-class events and behaviors, which allow programs to react to events without the use of callbacks or imperative operations. Instead, the program expresses dataflow relationships between events and behaviors (known generally as signals), and the language keeps their values up-to-date as the environment changes. FrTime is inspired and informed by work on functional reactive programming.

A key design goal in FrTime is to make it feel like Racket, rather than a completely new language. FrTime is distributed with the Racket programming environment. The core ideas have also been adapted to JavaScript, to create Flapjax, a language for interactive Web applications.
