Inspired by the ease with which Joe Gregorio put together a framework in Python using some components [1] I'm inspired to create some components of my own so the same thing can be done in Haskell. I'm aiming for creating some thing /really/ simple and I want to start with writing a templating system or a database wrapper. But first, what has been done in this area already already? I'm aware of at least some template like efforts [2]. For the templating system I don't think I want a DSL like approach (ala Lisp with (body (h1 "Foo")) etc. but rather a solution where code and templates are kept separate. Here's a really simple interface. compileTemplate :: Stringable a => a -> Template renderTemplate :: (Show a, Stringable b) => Template -> Map Stringable a -> b Or something along those lines. Compiling the template makes subsequent rendering faster and ByteString adds even more speed. With some templating language like so: <html> <head>...</head> <body> <h1>{{ title }}</h1> </body> </html> 'title' is looked up in the Map when the template is rendered. The other option would be inline Haskell code: <html> <head>...</head> <body> <h1><% postTitle title %></h1> </body> </html> Where 'title' is a record data type. There's also a middle ground like with Django's templates that supports restricted inline code. I guess the restriction is unnecessary in Haskell as we can disallow mutation of values quite easily (?). 1. http://bitworking.org/news/Why_so_many_Python_web_frameworks 2. http://blog.moertel.com/articles/2006/10/18/a-type-based-solution-to-the-str...
