What's this?

This program generates QR codes in ASCII art or Sixel 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
Usage: qrc [OPTIONS] [TEXT]

Options:
  -h, --help
    Show this help message
  -i, --invert
    Invert color

Text examples:
  http://www.example.jp/
  MAILTO:[email protected]
  WIFI:S:myssid;T:WPA;P:pass123;;
$ 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.

No arm64 binary

It would be great if there was a precompiled binary for arm64 on linux. Bonus points for silicon Mac.

awesome tool, but could the dependence code.google.com/p/rsc/qr change to github one

awesome tool, but could the dependence code.google.com/p/rsc/qr change to github repo.
https://github.com/SKatiyar/qr for example, btw are there official one?

Why move ? Check this out http://google-opensource.blogspot.com/2015/03/farewell-to-google-code.html
