	local list_n = split(i, "\n")
	local list_t = split(list_n[1],"\t")
	return list_t

	while true do
		local find_end = string.find(string, spt, find_index)
		if not find_end then
			spt_arr[spt_index] = string.sub(string, find_index, string.len(string))
			break
		end

		find_index = find_end + string.len(spt)
		spt_index = spt_index + 1
	end
	return spt_arr
end

------------------------main-------------------------
function main()
	local url = "http://qq.ip138.com/weather/sichuan/chengdu.wml"
	local con, ret = http.request(url)
	if con == nil then
		print ("nil")
	else
	--	print (con)
		local list_t = 	get_weather(con)
		print ('今天天气:',list_t[1],list_t[2],list_t[3],list_t[4])
	end
end

main()

其实开始是想做在awesome statbar显示天气的(字体图标的那种),现在终端获得天气已经写好!

明天再着手搞字体的转换问题!
