NEW HOME, NEW NAME

In March 2012 clj-processing project changed its home and name to Quil. You can find the new project here:

      https://github.com/quil/quil

This repository is no longer developed or maintained.

Processing for Clojure

This lib is a wrapper for the Processing project. Mixture of Clojure and Processing enables you to do live-coding and experiment easily.

Most of the function are covered; some have a slightly different name than in Java (partly because Clojure is confused by methods of the same arity but different argument types). Most of the constants are accessible.

How To Use It?

NOTE: project is currently going through some cleanups when it comes to lein/maven compatibility. Untill that's finished, you pretty much have to setup your project manually.

If you use mave or leiningn, just add the following to your project.clj:

    [processing-core/processsing.core "0.1.0"]

Manual Setup

Add Processing's core.jar to your classpath along with clj-processing jar and you're ready to go.

To use the OpenGL features, you also have to add gluegen-rt.jar, jogl.jar and opengl.jar from the $PROCESSING_DIR/libraries/opengl/library. You also need to pass the argument:

     -Djava.library.path=`$PROCESSING_DIR/libraries/opengl/library

to the JVM.

Then, create a JAR by running ant and also add the resulting file to your CLASSPATH.

Examples

The examples directory contains a simple script to get you going.

COMMON ISSUES

clj-procesing may not work if you're using add-classpath to put the Processing jars into your CLASSPATH. Please, use a "proper" way to set up your CLASSPATH (eg. with a special script like the clj on Clojure Wiki)

If your're using Clojure's proxy macro, you'll have to define the mouse handling methods to take one argument (which is just an instance of java.awt.event.MouseEvent class) and get all needed information (like mouse position etc) from that object. Also, accessing instance fields of the PApplet class from within proxy doesn't work.
