The ruby-processing group exists to collect together projects that support creating and running processing sketches in ruby. It is also designed to hide the inevitably high bus factor of what is an essentially one man band, but I am trying hard to make it otherwise (including evolving the code). You could play your part…
There are two main projects JRubyArt and propane, JRubyArt is the closest to the original ruby-processing and provides a ruby wrapper around the latest vanilla processing, it depends on a vanilla processing install (but can be configured to not require a jruby install). Propane is a configuration free, complete version of ruby-processing (does not require installed vanilla processing) that depends on an installed jruby (is slightly more experimental however since a modified PApplet is required with jdk9+ propane may take over in future). Propane is currently only available for MacOS and linux, and without significant input from Windows users it will remain so.
First degree was BSc hons Biochemistry from University of Surrey, I went on to specialize in xenobiotic metabolism (at first drugs, then industrial chemicals and pesticides). I later studied for a computer science degree with the Open University (BSc hons 2:1 but completed insufficient specific modules to be a named degree), course included some smalltalk but mainly java. Subsequently I dabbled a bit with C++, perl python, and even lisp, but got hooked on ruby, particulary ruby-processing. OS experience Windows-98 up to Windows-XP and mainly linux since 2004 (tried gentoo, fedora, even pardus) now using exclusively Archlinux and Mint (Debian). Since November 2012 I have been sole developer/maintainer of ruby-processing (did update for processing-2.0), and I have since developed JRubyArt and propane (for processing-3.0+) and ensured that jruby-184.108.40.206 (with support from jruby group) continued to work with ruby-processing, and its descendants.
