qr
Creates a QR code from STDIN
Description
qr is an optional builtin which generates a PNG format image based on the input from STDIN. qr must be run as a method.
Usage
<stdin> -> qr -> <stdout>
Examples
Write the PNG to disk
» out "Hello, World!" -> qr -> > qr.png
Display PNG in the terminal
» out "Hello, World!" -> qr -> open-image
Detail
qr sets stdout's data-type to be "image", which is defined in with the open-image optional builtin. So if you have that disabled then you may have to cast the output in some circumstances.
