Ruby QR code decoder?

Rate this Message:
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 image or b) is it possible to run a java command from ruby? Thanks for any guidance. Cameron *yes, I will be looking into obj-c eventually, but want to prototype asap --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Eric: Why so incredulous? My point is that I'd rather prototype something quickly for user testing before I try learn a completely new language. To anyone else interested: I found out how to execute java using %x| java ...| . I think latency would be an issue in the scenario I'm describing, but I'm going to give it a shot.

Just that in 10 months of asap you could have implemented any of: http://stackoverflow.com/questions/231741/qr-code-2d-barcode-coding-and-decoding-algorithms Nothing personal, just sayin'.

Eric, I think I see the confusion. Check http://www.ruby-forum.com/topic/198410, you'll see that the timestamps are borked (see your reply from 10 months ago). In any event, thanks for the link.

In any event, thanks for the link. There is nothing wrong with the timestamps. They're just European-style DMY.
