lua 获得天气信息

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!

#!/usr/bin/lua5.1
local http = require("socket.http")
------------------------split-------------------------
function get_weather(con)
    local s = "<b>.*<br\/><br\/>"
    local i ,j = string.sub(con, string.find(con,s))
    local i, n = string.gsub(i, "<br\/><br\/><b>","\n")
    local i, j = string.gsub(i, "<br\/>","\t")
    local i, j = string.gsub(i, "<\/b>","")
    local i, j = string.gsub(i, "<b>","")
    local i, j = string.gsub(i, "℃","°C")
    local i, j = string.gsub(i, "～","-")
    --  print(i,n+1)--所有天气
    local list_n = split(i, "\n")
    local list_t = split(list_n[1],"\t")
    return list_t
end

------------------------split-------------------------
function split(string, spt)
    local find_index = 1
    local spt_index = 1
    local spt_arr = {}
    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
        spt_arr[spt_index] = string.sub(string, find_index, find_end - 1)
        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
