# Omnipresence

Yet another presence checker for elixir.

## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `omnipresence` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:omnipresence, "~> 0.1.0"}
  ]
end
```

## Usage

```elixir
import Omnipresence

if present?(calculated_value()) do
  IO.puts("I'm present")
else
  IO.puts("I'm blank")
end

if blank?(nil) do
  IO.puts("I'm blank")
end
```

```elixir
raw_value
|> some_function()
|> Stream.map(&Omnipresence.presence/1)
|> Stream.reject(&is_nil/1)
|> Enum.each(fn value ->
  IO.inspect(value)
end)
```
