Optional Command Reference: 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.
