Scalixir

Scala syntax in Elixir!

On the left hand side Scalixir On the righthand Elixir equivalent

Features

• { and } instead of do and end - No more tedious block separators!
• ( and ) instead of { and } for tuples. Just because. And also for easier implementation of the feature above
• Single line defs declarations with =

Incoming features

• Lambda expressions { _ * 2 }
  • No more Enum.map fn a -> a * 2 end. Now its time for Enum.map {_ * 2}
  • Imagine a world where |> (&(&1 * &2)).() becomes |> {_ * _}.()

Instalation

Install Scalixir globally with

mix archive.install https://github.com/wende/scalixir/releases/download/v0.1/scalixir-0.0.1.ez

Then add it yo your project by adding these two lines to your Mix.exs file

def project do
    [app: :my_app,
     ...
     compilers: [:scalixir, :yecc, :leex, :erlang, :elixir, :app],
     elixirc_paths: ["lib", ".sex"]
    ]
  end

Now you can create *.sex files anywhere in your project and have fun with Scalixir

Example file

# Brackets instead of do/end blocks
defmodule MyModule {
  def somefunction(a, b \\ 10)
  def somefunction(a, b){
    case File.read("somefile"){
      # Parenthesis for tuples
      (:ok, content) -> content
      _ -> :not_ok
    }
  }
  def somefunction(a, 5){
    # Nothing yet here. But it will look like Enum.map a, { _ * 5 }
    Enum.map(a, fn b -> b * 5 end)
  }

  defmacro something(a, b){
    IO.puts "hey"
  }

  defmacrop deffun(){
    quote{
      def yo(){
        :yo
      }
    }
  }

  # Single line defs declarations with `=`
  defp two() = 2
}
