MixInstallExamples

A collection of simple Elixir scripts that are using Mix.install/2. (Requires Elixir v1.12+)

Example

Let's run the example benchee.exs script of the excellent Benchee benchmarking library.

$ git clone https://github.com/wojtekmach/mix_install_examples.git
$ cd mix_install_examples
$ cat benchee.exs
Mix.install([
  {:benchee, "~> 1.0"}
])

list = Enum.to_list(1..10_000)
map_fun = fn i -> [i, i * i] end

Benchee.run(
  %{
    "flat_map" => fn -> Enum.flat_map(list, map_fun) end,
    "map.flatten" => fn -> list |> Enum.map(map_fun) |> List.flatten() end
  },
  time: 10,
  memory_time: 2
)
