named_arguments

Named arguments in Elixir

This package abuses macros to use keyword lists and maps to mimic named arguments in Elixir.

Installation:

{:named_arguments, "~> 0.1.0"}

The usage is very simple:

defmodule Analyzer do
  use NamedArguments

  def query(opts \\ [aggregate: :sum, range: "1h"]) do
    IO.puts "running query with #{opts[:aggregate]} over range #{opts[:range]}"
  end
end

Analyzer.query()
# running query with sum over range 1h

Analyzer.query(aggregate: :avg)
# running query with avg over range 1h

While the above example shows Keyword list example, this works fine with maps as well.

You can check the test for more examples.
