This paper documents our experience using declarative languages to give secondary school students a first taste of Computer Science. The course aims to teach students a bit about programming in Prolog, but also exposes them to important Computer Science concepts, such as unification or searching strategies. Using Haskell's Snap Framework in combination with our own NanoProlog library, we have developed a web application to teach this course

“…The UHC Haskell compiler comes with a JavaScript backend as well, and matching higher-level extensions to its foreign function interface [6]. Like Fay, UHC provides automatic conversion of Haskell values to JavaScript objects, as well as importing arbitrary JavaScript expressions, with some parsing and wildcard expansion.…”

Foreign exchange at low, low rates a lightweight FFI for web-targeting Haskell dialects

We present a novel yet simple foreign function interface, designed for web-targeting Haskell dialects but also applicable to a wider range of high-level target languages. The interface automates marshalling, eliminates boilerplate code, allows increased sanity checking of external data, allows the import of functions as well as arbitrary expressions of JavaScript code, and is implementable as a plain Haskell '98 library without any modification to the Haskell compiler or environment. We give an implementation of this interface for the JavaScripttargeting Haste compiler, and show how the basic implementation can be further optimized with minimal effort to perform on par with Haskell's vanilla foreign function interface, as well as extended to support automatic marshalling of higher-order functions and automatic marshalling of host language exceptions. We also discuss how the interface may be extended beyond the web domain and implemented across a larger range of host environments and target languages.

“…Haste is by no means the only JavaScript-targeting compiler for a purely functional language. In particular, the GHC-based GHCJS [17] and UHC [8] compilers are both capable of compiling standard Haskell into JavaScript; the Fay [10] language was designed from the ground up to target the web space using a subset of Haskell; and there exist solutions for compiling Erlang [13] and Clean [9] to JavaScript as well. While the aforementioned compilers are the ones most interesting for purely functional programming, there exist a wealth of other JavaScript-targeting compilers, for virtually any language.…”

A seamless, client-centric programming model for type safe web applications

We propose a new programming model for web applications which is (1) seamless; one program and one language is used to produce code for both client and server, (2) client-centric; the programmer takes the viewpoint of the client that runs code on the server rather than the other way around, (3) functional and type-safe, and (4) portable; everything is implemented as a Haskell library that implicitly takes care of all networking code. Our aim is to improve the painful and error-prone experience of today's standard development methods, in which clients and servers are coded in different languages and communicate with each other using ad-hoc protocols. We present the design of our library called Haste.App, an example web application that uses it, and discuss the implementation and the compiler technology on which it depends.
