Indeed. If only it weren't stuck with a slow js interpreter.

yes, chrome on iOS is unsable because of this. I'd love to use Chrome more, but even lightweight js sites are tediously slow on chrome/ios

Not just the javascript either, Chrome becomes horrendously slow with week wifi signals where Safari is fine. For some reason only Apple apps can do the 3G/LTE/Wifi request pooling magic that they added in iOS 6.

I'm using a zsh function with similar functionality for exactly the same purpose: qrdisplay () { qrencode -o - "$1" | display }

"$*" is probably more likely what you want, and throwing in an extra "--" prevents it from choking on arguments that start with a dash.

you're right, but since I only ever used it for urls I never had noticed these problems

I saw this, thought "yeah right, gonna be more of a pain than depicted, why bother", downloaded & installed it anyway because I've got a stupid fondness for the idea (if not the awkward reality) of QR codes ... and not 2 hours later was using it for real. Dang handy, nicely implemented.

Thanks!

Only quibble is: how big a code can this viably render? tried something not particularly large for fun and just got a big "PNG" icon instead.

Unusable?! I've been using Chrome on my iPhone 4 for the past week and I haven't noticed a significant difference.

Thanks a lot! It's feedback like this that keeps me releasing this stuff for free :P

In terms of size: I think QR codes go up to 1024 bytes; anything larger and perhaps the Google Chart Image API would return an error, so you'd be quicklooking an empty file with a '.png' suffix, hence the generic PNG icon.

The next evolution of this script is to store larger text strings in a pastebin and then just display a QR code for the URL to that.

Chrome for iOS does this job beautifully :)

I jailbroke my phone and installed the Nitrous addon to give all apps access to the Nitro engine. Though, i'll admit it's not an option for everyone.
