Look, this even works when you’re offline :)

   qrencode -o - -l L -s 10 -- "$(xsel)" | display

I'm using a zsh function with similar functionality for exactly the same purpose:

    qrdisplay () {
	qrencode -o - "$1" | display
    }

Just keep in mind that Google's QR Code (Infographic) API has been deprecated.

Yeah, I was about to add that too. Sad, but fun to play with until it is gone ;)

You can do it locally with qrencode[1], which is available via MacPorts and Homebrew. It would probably simplify the script, too (especially if converted to bash).

On an X11 environment, I can select some text and get the same results on the command line with something like:

    xsel | qrencode -o - | feh -FZ

None of these commands are standard on any distribution, but you can easily install them or use alternatives. You can also make this an alias, hotkey, etc.

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

I created a bookmarklet that does the same thing for any website you're browsing. Makes it easy to transfer from PC to phone, assuming the phone can read QR codes. http://keyboardp.tumblr.com/post/38976790879/send-webpage-fr...

This is excellent – I find this more useful than the parent article.

I use Chrome to Phone with my android phone. One click on a button sends the current url to my browser, or I can select any text, right click it and send it to my phone where it is then available on my clipboard to paste wherever. It also keeps a history of all this on my phone so I can recall what I sent last week. That feature alone is why I'll probably never own an iPhone. Edit: Still a cool extension you've got t…

Chrome for iOS does this job beautifully :)

Would be even more useful if it could QR-ify any currently select text. I was just thinking of doing that myself.

I read through the comments, expecting to see a JS version of this, but I didn't find one so I made it:

  javascript:(function(){ var i = new Image();i.src = 'http://chart.apis.google.com/chart?cht=qr&chs=300x300&chl='+ encodeURIComponent(getSelection());i.onclick=function(){i.parentNode.removeChild(i)};i.setAttribute('style', 'position:fixed;top:50%;left:50%;margin:-150px 0 0 -150px;box-shadow:0 0 20px rgba(0,0,0,0.2)');document.body.appendChild(i)})();

Create a new bookmark, name it "QR Selection" and add the above code as the URL. Only tested in Chrome.

Edit: Added missing apostrophe.

Cool, I like it and would use it daily. I sometimes use dropbox like a pastebin for same thing. QR Code transfer is probably patent encumbered (like well almost everything). Nokia has app to do this but in reverse. Look at photo gallery on phone in their app. When you find picture you want to see, open browser on desktop and see QR code. Point camera at screen and the QR code in browser is replaced by image from phon…

According to Wikipedia, QR code is free of any license. http://en.wikipedia.org/wiki/QR_code

you can still patent applications of it.
