Hi all, I'm going to try to implement a version of Markdown tool[1] in Haskell. The application is rather simple: take a text file with some (simple) mark-up embedded in it and turn it into another text file, this time with XHTML markup. I need some guidelines on how to get started. I'll have to struggle with both the language itself (as I am a newcomer) plus with libraries that I may need. If I to do this in some convenient language, like Python, I'd use a lexer to parse the input, a state machine to build some internal representation and some serializer to write this into XHTML. Which approaches could you suggest for that kind of application in Haskell? I'd especially glad to hear about some "idiomatic" or "native" ways to solve the problem. I've made a quick search and found tools like Parsec, HaXML, Happy and WASH/HTML. Not sure which ones I'll need. [1] - http://daringfireball.net/projects/markdown/ TIA, max.
