diagrams-qrcode

This library is able to draw diagrams of QR codes using the diagrams library. In order to create the QR code itself, you may use either the haskell-qrencode library or qrcode library, both are supported. In order to draw and save the diagram to a file, we suggest using either the diagrams-svg library (pure Haskell, fast, SVG output only) or the diagrams-cairo library (requires Cairo, supports many different output targets, including SVG, PNG, PDF, PS and directly onto a GUI).

For example:

$ cabal install diagrams-qrcode haskell-qrencode diagrams-svg diagrams
$ cd examples/
$ echo 'https://github.com/meteficha/diagrams-qrcode/' | \
  runhaskell using-haskell-qrencode.hs > qrcode.svg
$ xdg-open qrcode.svg
