PipeHere <a href="https://travis-ci.org/vic/pipe_here"><img src="https://travis-ci.org/vic/pipe_here.svg"></a>
An Elixir macro for easily piping arguments at any position.
Usage
import PipeHere
The pipe_here macro lets you specify the argument position
while piping values by using the _ placeholder.
For example:
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:
2 |> x(1, _, 3) |> pipe_here
Note that while you can do stuff like:
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, the package can be installed as:
- Add pipe_here to your list of dependencies in
mix.exs:
def deps do
[{:pipe_here, "~> 1.0.0"}]
end
Is it any good?
