paiza.ioでelixir その65

概要

paiza.ioでelixirやってみた。
Process調べてみた。

サンプルコード

pid = spawn fn -> 
	IO.puts 5 * 7 
end
self
|> IO.inspect
Process.alive? pid
|> IO.inspect
Process.alive? self
|> IO.inspect
Process.info self
|> IO.inspect

defmodule ProcessTest do
	def do_receive do
		receive do
			{:key, msg} -> 
				"match " <> msg
			{:other, msg} -> 
				"not match" <> msg
		after
			1_000 -> 
				"after 1sec"
		end
	end
end

send self, {:key, "value"}
|> IO.inspect
send self, {:other, "other"}
|> IO.inspect
:erlang.process_info(self(), :message_queue_len)
|> IO.inspect
IO.puts ProcessTest.do_receive
:erlang.process_info(self(), :message_queue_len)
|> IO.inspect

IO.puts ProcessTest.do_receive
:erlang.process_info(self(), :message_queue_len)
|> IO.inspect

IO.puts ProcessTest.do_receive

実行結果
