ANN: loli: a minimal web dev DSL

loli is a DSL built on hack. It allows you to easily define routes, build your custom template backends through a simple Template interface, and integrate with other hack middleware.

• driver

  The simplest app looks like this

  import Network.Loli
  import Hack.Handler.Happstack
  
  main = run . loli - get "/" (text "loli power")
  

• route

  get "/hello" - do
    text "hello"
  

  will route "/hello" to a controller that outputs hello.

• middleware

  using a middleware is just as declaring

  middleware lambda
  

• template

  the template interface is

  class Template a where
    interpolate :: a -> String -> Context -> IO String
  

  Context is just [(String, String)]

  After implementing your own template engine, you can use

  output - your-engine-constructor "template-name"
  

• demo

  I put the source of a dummy paste app on itself:

loli is on hackage, lolipaste is in loli repo on github:

happy hacking
