awesome 脚本中加入天气

将这几天做的lua脚本和入到awesome脚本中。 目前缺点：可以获取天气信息，不过天气是文字形式的！

相关函数

------------------------regex-------------------------
function get_weather(con)
    local s = "<current_conditions>.*<\/forecast_conditions>"
    local i ,j = string.sub(con, string.find(con,s))
    local s = "\"[a-z0-9A-Z%s:%%]*\"" 
    local info
    for word in string.gmatch(i, s) do
            info = tostring(info).."\t"..tostring(word) 
    end
    local i, j = string.gsub(info, "\"","")
    local l = split(i,"\t")
    return l
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

添加控件widget

weather = widget({type = "textbox" })
vicious.register(weather, vicious.widgets.weather,
 function (widget, args)
    local http = require("socket.http")
    local url = "http://www.google.com/ig/api?weather=chengdu"
    local con, ret = http.request(url)
    if con == nil then
        return nil
    else
        local l =   get_weather(con)
        return '<span color="brown">WEATHER:</span><span  color="orange">'..l[2]..' '..l[4]..'°C</span>'
    end
 end
, 3600,"ZUUU")

添加到盘pannel

mywibox_top[s].widgets = {
       {
           mylauncher,
           mytaglist[s],
           mypromptbox[s],
           layout = awful.widget.layout.horizontal.leftright
       },
       mylayoutbox[s],
       mytextclock,
       s == 1 and mysystray or nil,
               spacer,
               uptime,
                   weather,
               spacer,
               weathericon,
       mytasklist[s],
       layout = awful.widget.layout.horizontal.rightleft
   }
