Clack - Web Application Environment for Common Lisp

Build Status Coverage Status Quicklisp dist

Clack is a web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack.

Usage

(defvar *handler*
    (clack:clackup
      (lambda (env)
        (declare (ignore env))
        '(200 (:content-type "text/plain") ("Hello, Clack!")))))

Open your web browser and go to http://localhost:5000/. You should get "Hello, Clack!".

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

Command-line interface

Clack provides a script to start a web server. It's useful when you deploy to production environment.

NOTE: Install Roswell before as it depends on it.

When you execute ros install clack, it copies clackup script to $HOME/.roswell/bin. Make sure the path is in your shell $PATH.

$ ros install clack
$ which clackup
/Users/nitro_idiot/.roswell/bin/clackup

$ cat <<EOF >> app.lisp
(lambda (env)
  (declare (ignore env))
  '(200 (:content-type "text/plain") ("Hello, Clack!")))
EOF
$ clackup app.lisp
Hunchentoot server is started.
Listening on localhost:5000.

Installation

(ql:quickload :clack)

# Clack - Web Application Environment for Common Lisp

[![Build Status](https://travis-ci.org/fukamachi/clack.svg?branch=master)](https://travis-ci.org/fukamachi/clack)
[![Coverage Status](https://coveralls.io/repos/fukamachi/clack/badge.svg?branch=master)](https://coveralls.io/r/fukamachi/clack) [![Quicklisp dist](http://quickdocs.org/badge/clack.svg)](http://quickdocs.org/clack/)

Clack is a web application environment for Common Lisp inspired by Python’s WSGI and Ruby’s Rack.

## Usage

“‘common-lisp
(defvar *handler*
(clack:clackup
(lambda (env)
(declare (ignore env))
’(200 (:content-type "text/plain") ("Hello, Clack!")))))
“‘

Open your web browser and go to [http://localhost:5000/](http://localhost:5000/). You should get "Hello, Clack!".

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

## Command-line interface

Clack provides a script to start a web server. It’s useful when you deploy to production environment.

NOTE: Install [Roswell](https://github.com/snmsts/roswell) before as it depends on it.

When you execute ‘ros install clack‘, it copies ‘clackup‘ script to ‘$HOME/.roswell/bin‘. Make sure the path is in your shell ‘$PATH‘.

$ ros install clack
$ which clackup
/Users/nitro_idiot/.roswell/bin/clackup

$ cat <<EOF >> app.lisp
(lambda (env)
(declare (ignore env))
’(200 (:content-type "text/plain") ("Hello, Clack!")))
EOF
$ clackup app.lisp
Hunchentoot server is started.
Listening on localhost:5000.

## Installation

“‘common-lisp
(ql:quickload :clack)
“‘
