Processing

This is the official source code for the Processing Development Environment (PDE), the “core” and the libraries that are included with the download.

Development of Processing 3 has started, so major changes are underway inside this repository. If you need a stable version of the source, use the tag processing-0227-2.2.1. Do not expect this code to be stable. Major changes include severe things like breaking libraries (due to chaining operations in PVector) or the removal of Applet as the base class for PApplet. Some of these will be sorted out before the release, others are simply being tested or are developments that are in-progress.

If you have found a bug in the Processing software, you can file it here under the “issues” tab. If it relates to the JavaScript version, please use their issue tracker. All Android-related development has moved to its own repository here, so issues with Android Mode, or with the Android version of the core library should be posted there instead.

The issues list has been imported from Google Code, so there are many spurious references amongst them since the numbering changed. Basically, any time you see references to changes made by processing-bugs, it may be somewhat suspect. Over time this will clean itself up as bugs are fixed and new issues are added from within Github. Help speed this process along by helping us!

The processing-web repository contains reference, examples, and the site. (Please use that link to file issues regarding the web site, the examples, or the reference.)

The instructions for building the source are here.

Someday we'll also write code style guidelines, fix all these bugs, throw together hundreds of unit tests, and solve the Israeli-Palestinian conflict.

But in the meantime, I ask for your patience, participation, and patches.
