. We dene HTML as an embedded domain specic language in Haskell. To this end, we have designed and implemented a combinator library which provides the means to create and modify HTML elements. Haskell's type classes are employed to enforce well-formed HTML to a large degree. Haskell can then be used as a meta language to map structured documents to HTML, to dene conditional content, to extract information from the documents, or to dene entire web sites. We introduce container-passing style as a programming convention for the library. We also pinpoint some shortcomings of Haskell's type system that make the task of this library's implementor tedious. Key words: embedded domain specic language, HTML, functional programming, type classes 1 Introduction Programming one web page in isolation is not hard. Programming an entire web site can be a nightmare. While simple HTML editors help with the rst task [23, 9], full blown web authoring systems are required for the other ta...
