Save it into another file

qrrs --read --terminal /tmp/qr.png /tmp/qr1.png

Almost the same result will be without terminal flag, but now instead of QrCode printed in terminal we will see text from it.

qrrs --read /tmp/qr.png /tmp/qr1.png

Create code using pipeline

Use "-" to signalize passing data via stdin.

$ echo "something" | qrrs - /tmp/something.png
$ qrrs -r /tmp/something.png
something

Invert colors

Create code specifying it's margin

Install

Nix

nix run github:Lenivaya/qrrs -- "your input"

Using last version through overlay in nixos config

Add this repository as an input to your flake:

nixpkgs.url = "nixpkgs/nixpkgs-unstable";
qrrs = {
  url = "github:lenivaya/qrrs";
  inputs.nixpkgs.follows = "nixpkgs";
};

Then use the overlay somewhere in your config:

{inputs, pkgs, ...}: {
  nixpkgs.overlays = [inputs.qrrs.overlays.default];
  environment.systemPackages = with pkgs; [qrrs];
}

NetBSD

pkgin install qrrs

From crates.io

cargo install qrrs

From github

cargo install --git https://github.com/Lenivaya/qrrs.git
