paiza.ioでelixir その66

概要

paiza.ioでelixirやってみた。
Scheduler調べてみた。

サンプルコード

defmodule FibSolver do
	def fib(scheduler) do
		send scheduler, {:ready, self()}
		receive do
			{:fib, n, client} ->
			    IO.puts "ok1"
				send client, {:answer, n, fib_calc(n), self()}
				fib(scheduler)
			{:shutdown} ->
			    IO.puts "ok3"
				exit(0)
		end
	end
	defp fib_calc(0), do: 1
	defp fib_calc(1), do: 1
	defp fib_calc(n), do: fib_calc(n - 1) + fib_calc(n - 2)
end

Enum.each 1..3, fn n ->
    IO.puts n
end
(1..3)
|> Enum.map(fn(n) ->
    IO.puts n
end)
spawn(FibSolver, :fib, [self()])
receive do
	{:ready, pid} ->
        IO.puts "ok0"
        send pid, {:fib, 9, self()}
	#{:answer, number, result, _pid} ->
    #    IO.puts "ok1"
end
receive do
	#{:ready, pid} ->
    #    IO.puts "ok0"
    #    send pid, {:fib, 9, self()}
	{:answer, number, result, _pid} ->
        IO.puts "ok2"
        IO.puts result
        send _pid, {:shutdown}
end
