Scanning and running

Generally the QR code scanner must support binary data. Otherwise the applications will not be able to run and most likely SIGSEGV.

Computer

zbar can be used to scan the qr code with the webcam:

zbarcam --raw >qr
chmod +x qr
./qr

or from an image:

zbarimg --raw image.png >qr
chmod +x qr
./qr

Smartphone

Use BinaryEye to scan the qr code and save it. Transfer the file to a computer and run it there.

Building

Each directory contains a Makefile which will build the binary and the qr code. So simply running make in a directory will build it. This repository contains a nix development environment with all the tools. Just run the following if you have support for flakes enabled to enter it.

nix develop

This command assumes that experimental-features = nix-command flakes in your nix.conf.
