Elixir script the shell
– Andi, 2018-10-17
I’m using Elixir as a scripting language for the shell
And it’s that easy …
Write a file, hello.exs
for example.
#!/usr/bin/env elixir
defmodule Greeter do
def hello(name), do: IO.puts "Hello, #{name}!"
end
# Main
Greeter.hello( hd(System.argv() )
Don’t forget to chmod +x hello.exs
and then use the script from
the terminal with
$ ./hello World
Hello, World!
For more complex scenarios you can use Elixir‘s OptionParser and all the sugar that comes with that beautiful language.
