README

FitEx Build Status Hex.pm package version

FitEx is a little Macro-Module which provides a alternative way for function definitions. If you need an anonymous functions which takes a single argument like this:

fn param -> param + 1 end

you can use the short version:

f it + 1

I know, I know... You could use &(&1+1). That's right, but maybe the provided syntax is a little bit more readable. And anyway, I more or less created this to try out macros, inspired by the Kotlin lambda syntax: http://kotlinlang.org/docs/reference/lambdas.html

Installation

Add FitEx as a dependency in your mix.exs file:

  defp deps do
    [
      FitEx: "~> 0.0.1"
    ]
  end

and run mix deps.get.

Usage

By using FitEx you can write one parameter functions with the f macro. The parameter is named 'it'.

defmodule SomeModule do
  use FitEx

  def some_function do
    # One liner
    func = f it + 1

    # or multi line function-body
    func = f do
      it_plus_one = it + 1
      it_plus_one * 2
    end
  end

end
