paiza.ioでelixir その43

概要

paiza.ioでelixirやってみた。
変数のスコープ調べてみた。

サンプルコード

defmodule Main do
	stack = [] 
	stack = stack ++ [5]
	Enum.map(String.split("9 9 - 9 9 / .", " "), fn s ->
		#IO.puts s
		stack = stack ++ [6]
		IO.inspect stack
	end)
	stack = stack ++ [2]
	IO.inspect stack
end

IO.puts ""

defmodule Main do
	stack = [] 
	stack = stack ++ [5]
	s = String.split("9 9 - 9 9 / .", " ")
	n = length(s) - 1
	#IO.puts n
	#IO.inspect s
	for i <- 0..n do 
		#IO.puts Enum.at(s, i)
		stack = stack ++ [6]
		IO.inspect stack
	end
	stack = stack ++ [2]
	IO.inspect stack
end

実行結果

[5, 6]
[5, 6]
[5, 6]
[5, 6]
[5, 6]
[5, 6]
[5, 6]
[5, 2]

[5, 6]

[5, 6]
[5, 6]
