Clack - Web Application Environment for Common Lisp

Clack is a web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack. Your awesome framework should base on this.

Usage

(defpackage simple-app  
  (:use :cl  
        :clack))  
(in-package :simple-app)  
 
(defvar *handler*  
    (clackup  
      #'(lambda (env)  
          '(200 (:content-type "text/plain") ("Hello, Clack!"))))) 

Now access http://localhost:5000/ and Clack should show you "Hello, Clack!".

To stop the server, execute (clack:stop *handler*).

Installation

Clack is available on Quicklisp.

(ql:quickload :clack)
