Or even like this so it is more traditionally pipe’y:
defmodule PipeMapInto do
defmacro pipe_map_into(val_ast, applicitives_ast) when is_list(applicitives_ast) do
do_pipe_map_into(val_ast, applicitives_ast)
end
defp do_pipe_map_into(val_ast, []), do: []
defp do_pipe_map_into(val_ast, [applicitive_ast | rest_asts]) do
[ quote do
unquote(val_ast) |> unquote(applicitive_ast)
end
| do_pipe_map_into(val_ast, rest_asts)
]
end
end
And used like:
iex> import PipeMapInto
PipeMapInto
iex> 2 |> pipe_map_into([
...> add(2),
...> add(5),
...> mul(10),
...> ])
[4, 7, 20]
Side Note: I’m noticing a lot of replies to old posts that have no replies, just trying to answer old posts or so?
