==========
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
```
