Sunroof is a Haskell-hosted Domain Specific Language (DSL) for generating JavaScript.
Sunroof is built on top of the JS-monad, which, like the Haskell IO-monad, allows
access to external resources, but specifically JavaScript
resources. As such, Sunroof is primarily a feature-rich foreign
function API to the browser's JavaScript engine, and all the browser-specific
functionality, including HTML-based rendering, event handling, and
drawing to the HTML5 canvas.
It uses monadic reification, to reify a deep embedding of the JS-monad,
and from this embedding it generates JavaScript.
The Sunroof DSL has the feel of native Haskell, with a simple
Haskell-based type schema to guide the Sunroof programmer.
Furthermore, because it generates code,
Sunroof can offer Haskell-style concurrency patterns, like MVars and Channels.
In combination with a web services package like kansas-comet,
the Sunroof compiler offers a robust platform to build interactive web applications,
giving the ability to interleave Haskell and JavaScript computations
with each other as needed (sunroof-server).
