A new version for jdk11 use, does not require an installed
vanilla processing, however if installed you can use processing-ide to download libraries. Configuration file is incompatible with that of previous version of JRubyArt (and you should move or rename old
config.yml to keep it). This version will run with a default configuration file but you won't be able to use processing libraries, until you match configuration to your setup.
A suitable version of ruby (MRI
ruby 2.3+ or
jruby-188.8.131.52) to download gem.
open-jdk11.03+ currently FX2D is not included.
You can if you wish leave configuration to the
new autoconfig tool (delete or rename existing config to do this). The config file is
config.yml in the
~/.jruby_art folder, the autoconfig gets run on
k9 --install expected to just work.

Install Steps (assumes you have requirements above)
gem install jruby_art --pre k9 --install # installs jruby-complete-184.108.40.206 and downloads and installs samples to ~/k9_samples cd ~/k9_samples/contributed k9 --run jwishy.rb # if you have jruby-220.127.116.11 installed or config `JRUBY: false` # to use jruby-complete set `JRUBY: false` in config
Create sketches from built in templates
k9 --create fred 200 200 # basic sketch fred.rb k9 --create fred 200 200 p2d # basic P2D sketch fred.rb
To create either a
class wrapped sketch or
emacs sketch set
template: class or
template: emacs in config.yml
def setup sketch_title 'My Sketch' end def draw background 0 fill 200 ellipse width / 2, height / 2, 300, 200 end def settings size 400, 300 end
be prepared to
KILL the odd java process (ie when sketch does not exit cleanly)
k9 --watch sketch.rb # NB: doesn't work with FX2D render mode
Open pry console on sketch
k9 --live sketch.rb # pry is bound to Processing.app # needs `jruby -S gem install pry`
Worked Examples and, The-Nature-of-Code-Examples-for-JRubyArt feel free to add your own, especially ruby-2.2+ syntax now we can. These can now be downloaded using
k9 --install please move existing
k9_samples if you wish to keep them.
