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

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''. And yeah, there seem to be any number of system call solutions. -eric On Nov 1, 12:09 pm, ckundo <cku...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Eric: Why so incredulous?

Thanks, I''ll give those a shot.

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.
