NAME

qr - script to create QR codes at the command line

SYNOPSIS

qr [--help] [--factory=FACTORY] [--optimize=OPTIMIZE] [data]

DESCRIPTION

This script uses the python qrcode module. It can take data from stdin or from the commandline and generate a QR code. Normally it will output the QR code as ascii art to the terminal. If the output is piped to a file, it will output the image (default type of PNG).

OPTIONS

 -h, --help

Show a help message.

 --factory=FACTORY

Full python path to the image factory class to create the image with. You can use the following shortcuts to the built-in image factory classes: pil (default), pymaging, svg, svg-fragment, svg-path.

 --optimize=OPTIMIZE

Optimize the data by looking for chunks of at least this many characters that could use a more efficient encoding method. Use 0 to turn off chunk optimization.

 data

The data from which the QR code will be generated.
