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
},
