Elixir Return Helpers

Description

Simple library that adds a piping possibility for easy returning from pipes Documentation https://hexdocs.pm/return_helpers/api-reference.html

Imagine

socket =
  socket
  |> assign(valid: true)
{:noreply, socket}

to write like:

socket
|> assign(valid: true)
|> noreply()

or:

socket |> assign(valid: true) |> noreply()

Looks cleaner ?

Examples

iex> socket = %{}
%{}
iex> socket |> ok()
{:ok, %{}}
iex> socket |> noreply()
{:noreply, %{}}
iex> %{} |> to_tuple(:error, "params") 
{:error, %{}, "params"}
iex> "34" |> between_strings("12", "56")
"123456"
