CLI QR code generator and reader written in rust
QRrs is a simple, cross-platform, command-line utility written in rust for working with qr codes (what actually follows from the name).
Generate code, than read it qrrs "Something" /tmp/qr.png $qrrs --read /tmp/qr.png Something Print generated code to term qrrs -t "Something" /tmp/qr.png ██████████████████████████████████████████████████████████████ ▄▄▄▄▄ █▄ █▄▄█ ▄▄▄▄▄ ████████ █ █ █▀▄████ █ █ ████████ █▄▄▄█ █ ▄█▀▄█ █▄▄▄█ ████████▄▄▄▄▄▄▄█ ▀ ▀ █▄▄▄▄▄▄▄████████▄███ █▄▄ ▄▀ ▀▄▄▄ █▀▄████████▄ ▀█▀▄▄▀▄▀▀▄█▀▄█ █▄ ▀████████▄█▄██▄▄▄▀▀▀█ ▄▀█ ▀█▄ ████████ ▄▄▄▄▄ █▄▀▄▀ ▄▄▀ ██ █████████ █ █ █▄█▀ ▀▄▄█ ▀▀ ▀████████ █▄▄▄█ ██▀ ▄█▀ ▀ ████████████▄▄▄▄▄▄▄█▄▄▄█▄▄▄▄█▄██▄█████████████████████████████████▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ Show code as text in terminal qrrs --read --terminal /tmp/qr.png ██████████████████████████████████████████████████████████████ ▄▄▄▄▄ █▄ █▄▄█ ▄▄▄▄▄ ████████ █ █ █▀▄████ █ █ ████████ █▄▄▄█ █ ▄█▀▄█ █▄▄▄█ ████████▄▄▄▄▄▄▄█ ▀ ▀ █▄▄▄▄▄▄▄████████▄███ █▄▄ ▄▀ ▀▄▄▄ █▀▄████████▄ ▀█▀▄▄▀▄▀▀▄█▀▄█ █▄ ▀████████▄█▄██▄▄▄▀▀▀█ ▄▀█ ▀█▄ ████████ ▄▄▄▄▄ █▄▀▄▀ ▄▄▀ ██ █████████ █ █ █▄█▀ ▀▄▄█ ▀▀ ▀████████ █▄▄▄█ ██▀ ▄█▀ ▀ ████████████▄▄▄▄▄▄▄█▄▄▄█▄▄▄▄█▄██▄█████████████████████████████████▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ 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.pngqrrs -r /tmp/something.png something
Create code specifying it's margin
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 ] ; } cargo install --git https://github.com/Lenivaya/qrrs.git
