Hack: a sexy Haskell Webserver Interface

Hack is a lazy port of Rack: the ruby webserver interface.

What does a hack app look like

module Main where

import Hack
import Hack.Handler.Kibro

hello :: Application
hello = \env -> return $ Response 
    { status  = 200
    , headers = [ ("Content-Type", "text/plain") ]
    , body    = "Hello World"
    }

main = run hello

1 minute tutorial

Install Hack

cabal install hack

Install Kibro (the only handler at the moment)

cabal install kibro

Install lighttpd 1.4.19 (used by kibro)

wget http://www.lighttpd.net/download/lighttpd-1.4.19.tar.gz
tar zxfv lighttpd-1.4.19.tar.gz
cd lighttpd-1.4.19
./configure --prefix=$HOME
make
make install

Create a new Kibro project

kibro new hello-world

Test if Kibro works

cd hello-world
kibro start

Create our hack app

put the following code in src/Main.hs

module Main where

import Hack
import Hack.Handler.Kibro

hello :: Application
hello = \env -> return $ Response 
    { status  = 200
    , headers = [ ("Content-Type", "text/plain") ]
    , body    = "Hello World"
    }

main = run hello

restart kibro

kibro restart
