Processing.js 1.4.8 released!

It's been a few weeks and PRocessing.js got a few PRs merge in, so it's time for a new release: say hello to 1.4.8! This version has some fixes to PVector's rotate, support for randomGaussian(), and several unit tests to make sure those fixes pass muster. You can download the new version of Processing.js over on the download section, and let us know what's still missing!

Want to help out?

We're also happy to get help in the form of pull requests to add functionality to Pjs, or to simply fix small errors that were found. You don't have to be a code wizard to contribute: if you simply know of a function or a constant that's missing, feel free to fork the code, patch what you think needs patching, and file a Pull Request so that we can merge your improvement in! Don't know where to start? Drop into our IRC channel, #processingjs on irc.mozilla.org, and we'll be happy to help you get the most out improving Processing.js!

About Processing.js

Processing.js is the sister project of the popular Processing visual programming language, designed for the web. Processing.js makes your data visualizations, digital art, interactive animations, educational graphs, video games, etc. work using web standards and without any plug-ins. You write code using the Processing language, include it in your web page, and Processing.js does the rest. It's not magic, but almost.

Originally developed by Ben Fry and Casey Reas, Processing started as an open source programming language based on Java to help the electronic arts and visual design communities learn the basics of computer programming in a visual context. Processing.js takes this to the next level, allowing Processing code to be run by any HTML5 compatible browser, including current versions of Firefox, Safari, Chrome, Opera, and Internet Explorer. Processing.js brings the best of visual programming to the web, both for Processing and web developers.

Everything you need to work with Processing.js is here. You can download the most recent version of Processing.js, read Quick Start Guides for Processing Developers or JavaScript Developers, learn about the Processing language and Processing.js render modes, consult the Reference, and of course view many existing demos that use Processing.js. You can also get involved with the Processing and Processing.js communities, both of which are active and and looking for new users and developers.

Whether you're an advanced Processing developer or completely new, whether you're a pro with web technologies or just getting started, Processing.js bridges the gap between these two powerful technologies.
