QR Code Generator for lbstanza

This repository contains a stanza wrapper around the nayuki/QR-Code-generator project. This allows for a user to create a QR code representation of any passed string.

Example:

defpackage SomeTest :
  import core
  import QRCode/QRCode
  import QRCode/Encoder


def main () :
  val encoder = QRCodeEncoder(ECC_LOW, MASK_AUTO)
  val qr = encode-text(encoder, "http://lbstanza.org")
  println("%~" % [qr])

Note that I haven't been able to photograph the console output with my iphone and get the link yet. This library also contains a tool for generating a PNG image of the QR Code using lbstanza-cairo.

Build

$> git submodule update --init
$> sudo apt install build-essentials libcairo2-dev
$> make

Cairo is needed to generate the PNG image of the QR code.

Run Tests

$> make tests
stanza build
stanza build qrcode-tests
QRCODE_SHARED_LIB="./QRCode.so" ./qrcode-tests
[Test 1] gen-text-qrcode
