REnum

Extensions for and aliases Enumerable modules inspired by Ruby and Rails.ActiveSupport. It also provides full support for native functions through metaprogramming.

Installation

def deps do
  [
    {:r_enum, "~> 0.1.0"}
  ]
end

Usage

# Many useful functions.
iex> REnum.compact([1, nil, 2, 3])
[1, 2, 3]
iex> REnum.tally(~w(a c d b c a))
%{"a" => 2, "c" => 2, "d" => 1, "b" => 1}
iex> |> REnum.grep(["foo", "bar", "car", "moo"], ~r/ar/)
["bar", "car"]
iex> REnum.reverse_each([1, 2, 3], &IO.inspect(&1))
# 3
# 2
# 1
[1, 2, 3]
# Aliases.
iex> REnum.select([1, 2, 3], fn x -> rem(x, 2) == 0 end) == Enum.filter([1, 2, 3], fn x -> rem(x, 2) == 0 end)
true
# Can use Elixir's Enum functions too.
iex> REnum.find([2, 3, 4], fn x -> rem(x, 2) == 1 end)
3
iex> REnum.sort([3, 2, 1])
[1, 2, 3]
