PiCrate is both a `library` and an `app` that allows you to create [processing][processing] sketches in ruby on the [RaspberryPI][PI] (or 64 bit linux). PiCrate is available as a gem (from [rubygems][rubygems]), it requires [JRuby][jruby] to both install and run. It does not depend on a vanilla processing install ( _cf_ JRubyArt).Tested on raspbian Buster on RaspberryPI3B+ and RaspberryPI4, also works on Manajaro distro (64bit) on RapsberryPI4.
#### Executable ####
PiCrate sketches are executable scripts that (but without the executable permission), that will run directly from jruby.
```bash
jruby my_sketch.rb
```
The gem executable is `picrate`, which can be used to install samples (and to configure [GeanyIDE][geany]) and some processing libraries
#### Library ###
Your PiCrate sketches need to `require` the `picrate` library, and can be run with `jruby`.
* Command line interface (typically using vim as editor)
* Gui interface, sketches can be run from [GeanyIDE][geany]
* Use --dev flag to speed start-up
