# PipeHere 
[](https://twitter.com/vborja)
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
```
