Eqrcode

Simple QR Code Generator written in Elixir with no other dependencies.

To generate the SVG QR code:

qr_code_content = "your_qr_code_content"

qr_code_content
|> EQRCode.encode()
|> EQRCode.svg()

Options

You can also pass in options into EQRCode.svg():

qr_code_content
|> EQRCode.encode()
|> EQRCode.svg(%{color: "#cc6600", shape: "circle"})

For now, you can specify the color of the QR code in hexadecimal format, or the shape of each individual pixel. We only allow either square or circle for the shape option.

Default options are %{color: "#000", shape: "square"}.

Installation (pending)

If available in Hex, the package can be installed by adding eqrcode to your list of dependencies in mix.exs:

def deps do
  [
    {:eqrcode, "~> 0.1.0"}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/eqrcode.

Credits

We reused most of the code from sunboshan/qrcode to generate the matrix required to render the QR Code. We also reference rqrcode on how to generate SVG from the QR Code matrix.
