paiza.ioでelixir その209

概要

paiza.ioでelixirやってみた。
練習問題やってみた。

練習問題

jsonパーサーを書け。

方針

agentを使う。
正規表現を使う。
request.intent.slots.message.valueで、指定する。

サンプルコード

defmodule Json do
	use Agent
	def start_link() do
		Agent.start_link(fn -> 
            ""
		end, name: __MODULE__)
	end
	def set(x) do
		Agent.update(__MODULE__, fn v ->
	        x
		end)
	end
	def get() do
		Agent.get(__MODULE__, fn v ->
			v
		end)
	end
	def get(s) do
		Agent.get(__MODULE__, fn v ->
		    o = String.split(s, ".")
			v = String.replace(v, "\n", "")
			v = String.replace(v, "\t", "")
			v = String.replace(v, " ", "")
			#IO.puts(length(o))
			if length(o) == 5 do
			    #request.intent.slots.message.value
			    reg = Regex.compile!("\"request\":.+intent\":.+slots\":.+message\":.+value\":\"(?<kore>.+)\",\"")
			    #reg = ~r/(?<prefix>.*?)\|(?<main>.*?)\|(?<sufix>.*)/
                #IO.inspect Regex.named_captures(reg, "pre_value|main_value|sufix_value")
                #mat = Regex.named_captures(~r/\"request\":.+intent\":.+slots\":.+message\":.+value\":\"(?<kore>.+)\",\"/, v)
                mat = Regex.named_captures(reg, v)
                ma = mat["kore"]
                m = String.split(ma, "\"")
                Enum.at(m, 0)
            end
            #v
		end)
	end
end
