I'd like to use be able to decode QR codes that people submit to my
rails app. I'm using phonegap for iPhone, so I need to create a work-
around for a native QR code reader. The best I can come up with is
having someone take a picture of the code and submit it, then have
ruby parse it.*
I've searched this forum and online, and all I can find is the zxing
library for Java. Question is:
a) is there a rails plugin or a ruby gem that can decode a qr code
or b) is it possible to run a java command from ruby?
Thanks for any guidance.
*yes, I will be looking into obj-c eventually, but want to prototype
