This program generates QR codes in ANSI colors, Sixel or Unicode Block Elements format for text terminals, e.g., console, xterm (with -ti 340 option to enable Sixel), mlterm, Windows command prompt and so on.

Use case

You can transfer data to smartphones with a QR code reader application from your terminal.

Usage

qrc program takes a text from command-line argument or standard input (if no command-line argument) and encodes it to a QR code.

$ qrc --help
...
$ qrc https://fumiyas.github.io/
...
$ qrc 'WIFI:S:Our-ssid;T:WPA;P:secret;;'
...

You can get a QR code in Sixel graphics if the standard output is a terminal and it supports Sixel.
