==========

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:

```elixir
fn param -> param + 1 end
```

you can use the short version:

```elixir
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:

```elixir
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'.

```elixir
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
```
