How to detect a Raspberry Pi button press in Processing?

Hi folks!

Here’s my situation: I have a RPi 1 B+, successfully running Processing thanks to this resource: http://scruss.com/blog/2014/01/07/processing-2-1-oracle-java-raspberry-pi-serial-arduino-☺/

I’ve gotten Processing to recognize the Pi’s Serial Input thanks to this: http://www.raspberrypi-spy.co.uk/2013/12/free-your-raspberry-pi-serial-port/

I’ve used Adafruit’s Retro Gaming Controls tutorial to connect buttons (I only need two, simple buttons) directly to the Pi: https://learn.adafruit.com/retro-gaming-with-raspberry-pi/buttons

Finally, I’ve connected a button and confirmed that the RPi is seeing the button press using this simple Python script from O’Reilly: http://razzpisampler.oreilly.com/ch07.html

The remaining problem, then, is that Processing can’t see any button input.

As mentioned elsewhere, Gohai has brought up the idea of RPi support, including GPIO recognition -- which would be exactly what I need, too bad I can’t wait: http://forum.processing.org/two/discussion/9658/gsoc-2015-proposal-raspberry-pi-and-armv7hf-support

So, is the only way to do this NOW by using an Arduino to handle the buttons and pass that back to Processing? And if so, can someone point me in the right direction to do so?

Sorry for all the links; I’m not trying to promote them, I just thought it would help if people could see where I was coming from. THANK YOU!

Apparently Processing was available for RPi later that year: https://www.raspberrypi.org/blog/now-available-for-download-processing/

I haven’t actually used it yet, but in case anyone else comes across this question I wanted to put it out there!

@sca610 You don't need Arduino or those outdated tutorials, just have a look at https://github.com/processing/processing/wiki/Raspberry-Pi and use the latest P5 version

@gohai -- thanks for the link, a full Raspbian image with Processing pre-installed sounds handy.
