Elixir Prelude

Small set of useful utility functions.

Forked to release on Hex.pm, see: houshuang/elixir-prelude#1

Installation

1. Add elixir_prelude to your list of dependencies in mix.exs:

def deps do
  [{:elixir_prelude, "~> 0.2"}]
end

Usage

The most useful utility is provided by Prelude.Map to work with deeply nested Maps or Structs.

defmodule Data do
  defstruct data: %{}
end

Prelude.Map.deep_put(%Data{}, [:data, :b, :c, :d], 2)
#=> %Data{data: %{b: %{c: %{d: 2}}}}

Prelude.Map.deep_get(%Data{data: %{b: %{c: %{d: 2}}}}, [:data, :b, :c, :d])
#=> 2

Prelude.Map.del_in(%Data{data: %{b: %{c: %{d: 2}}}}, [:data, :b, :c, :d])
#=> %Data{data: %{b: %{c: %{}}}}

Other modules:

• Prelude.Atom
• Prelude.List
• Prelude.String

This package has a set of functions that I extracted from projects I worked on (mainly this). Some are very trivial, others (especially in the Prelude.Map module) are more involved. I am mainly putting it together for my own future reuse, but some of it might be useful to others. I would like to add tests, and I will keep adding functions as they come up. Pull requests or suggestions for new functions, better APIs etc are welcome (tests would be awesome).
