An Elixir macro for easily piping arguments at any position.

## Usage

```elixir

import PipeHere

```

The `pipe_here` macro lets you specify the argument position

while piping values by using the `_` placeholder.

For example:

```elixir

pipe_here( 2 |> x(1, _, 3) )

# expands to

x(1, 2, 3)

```

The `pipe_here` macro can also be used at the end of a pipe:

```elixir

2 |> x(1, _, 3) |> pipe_here

```

Note that while you can do stuff like:

```elixir

a |> b(1, _) |> c |> d.(2, _, 3) |> pipe_here

```

every member of the pipe can at most have just one `_` placeholder.

## Installation

[Available in Hex](https://hex.pm/packages/pipe_here), the package can be installed as:

  1. Add pipe_here to your list of dependencies in `mix.exs`:

```elixir

def deps do

  [{:pipe_here, "~> 1.0.0"}]

end

```
