[__Nebula__](https://hex.pm/packages/nebula) is a small library for colored ([ANSI](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors)) output in Erlang/Elixir. It's can be useful when you need to create user-friendly command-line application.

### Installation

Just add `{nebula, "0.1.1"}` to your rebar.config file and run following command:

```

➜ ~ make compile

```

or if you want to use this package with `Elixir` add `{:nebula, "~> 0.1.1"}` to your `mix.exs` and run following command:

```

➜ ~ mix deps.get

```

### Usage

Using with Erlang:

```erlang

update_something() ->

  %% ...

  %% ...

  nebula:print(green, "Something has been updated successfully!").

```

Using with LFE (Lisp Flavoured Erlang):

```lfe

(defun update_something ()

    (nebula:print :GREEN "Something has been updated successfully!"))

```

Using with Elixir:

```elixir

def update_something do

  # ...

  # ...

  :nebula.print(:green, "Something has been updated successfully!")

end

```
