Raspbian Buster installs OpenJDK11 (hard float) and that is just fine, if you have more that one version of java installed you could use `update-alternatives` tool to manage their use. NB: Will not work with OpenJDK-8.
__Then install JRuby see__ [jruby][jruby].
```bash
jgem install picrate
```
__For a first install:-__
```bash
picrate --install # no args, install samples and geany config
# or
picrate -i Samples # to omit geany config
```
This installs example sketches in `~/sample_sketches` and ties them into a `geany` project `picrate.geany`. It should also be possible to run sketches from the `geany` ide.
__Install processing libraries__
```bash
picrate -i Sound
picrate -i video # install beta verion of vanilla video for now
```
To create a template sketch from the command line:-
```bash
picrate -c my_sketch 600 400
```
creates file my_sketch.rb
```ruby
#!/usr/bin/env jruby
# frozen_string_literal: false
require 'picrate'
class MySketch < Processing::App
def settings
size 200, 200
end
def setup
sketch_title 'My Sketch'
end
def draw
end
end
MySketch.new
```
Edit in `vim` (at command line) or `geany` (gui), you may need to install `vim`
```bash
vim my_sketch.rb
:!jruby % # from vim runs the sketch
```
To run sketches from command line:-
```bash
jruby my_sketch.rb
```
Or even `chmod +x my_sketch.rb` to make an executable script.
See [editors][geany] geany, for how to run sketches from a gui.
