  2. Add Pandex to mix.exs as follows:

    defmodule YourApp.Mixfile do
      defp deps do
        [
          {:pandex, "~> 0.1.1"}
        ]
      end
    end
  3. Run mix deps.get to install Pandex.

  4. Add Pandex your application block in mix.exs

    defmodule YourApp.Mixfile do
      use Mix.Project
    
      def application do
        [applications: [:logger, :pandex]]
      end
    end

Usage

Pandex follows the syntax of <format from>_to_<format to> <string>

Using with your app

defmodule YourApp do
  import Pandex

  def convert(string)  do
    {:ok, output} = markdown_to_html string
    IO.puts output
  end
end

You can also give a file as an input. The output will however be a string.

defmodule YourApp do
  import Pandex

  def convert(file)  do
    {:ok, output} = markdown_file_to_html file
    IO.puts output
  end
end
