AppleScript每隔几分钟读取一次数据

我运行一个屏幕，在菜单栏上显示一些数据

变量取自“~/Desktop/\u MyData.plist”

但是，当_MyData.plist上的数据发生更改时，一切正常

如何使脚本获取新数据？我想我们不能期望AppleScript检测到文件更改，然后运行脚本，但是有没有办法在空闲时获取plist数据并保持整个脚本的运行

以下是仅获取数据的部分：

property theAccountNumberFromPlist : ""
property SNNumber : ""
property appName : ""
property devicesID : ""
property domainEMAIL : ""
property fullEmail : ""
property purchaseDate : ""
property thename : ""
property theList : ""

set the plistfile_path to "~/Desktop/_MyData.plist.plist"
tell application "System Events"
    set p_list to property list file (plistfile_path)
    -- read the plist data

set theAccountNumberFromPlist to value of property list item "AccountNumber" of p_list as text
set SNNumber to value of property list item "SNNUMBER" of p_list as text
set appName to value of property list item "appName" of p_list as text
set devicesID to value of property list item "devicesID" of p_list as text
set domainEMAIL to value of property list item "domainEMAIL" of p_list as text
set fullEmail to value of property list item "fullEmail" of p_list as text
set purchaseDate to value of property list item "purchaseDate" of p_list as text
set thename to value of property list item "thename" of p_list as text

结束语

以下是整个脚本：

使用空闲处理程序

on idle
-- do your stuff
return 5 -- idle handler will be executed again in 5 seconds.
end 

因此，您需要将脚本另存为应用程序。以下是：

保持打开应用程序的空闲和退出处理程序

默认情况下，接收运行或打开命令的脚本应用程序 处理单个命令，然后退出。相比之下，一家银行则保持营业 脚本应用程序（另存为“在脚本编辑器中保持打开状态”）保持不变 启动后打开

保持打开的脚本应用程序之所以有用，有以下几个原因：

• 保持打开脚本应用程序可以在中接收和处理其他命令 添加到运行和打开。这允许您使用脚本应用程序 作为脚本服务器，在运行时提供 可由任何其他脚本调用的处理程序

• 保持打开脚本应用程序可以执行定期操作，即使在 后台，只要脚本应用程序正在运行

两个特定的处理程序经常保持打开脚本应用程序 提供一个空闲处理程序和一个退出处理程序

空闲处理程序

如果保持打开脚本应用程序包含空闲处理程序， AppleScript通过以下方式发送脚本应用程序周期性空闲命令： 默认情况下，每30秒允许它在以下情况下执行后台任务 它不执行其他操作

如果空闲处理程序返回正数，则该数字将成为 调用处理程序的速率（秒）。如果处理程序 返回一个非数值，速率不变。您可以返回0 以保持30秒的默认延迟

例如，当保存为“保持打开”应用程序时，以下 脚本每5秒蜂鸣一次：

空闲时
嘟嘟声
返回5
结束空闲

处理程序返回的结果只是最后一条语句的结果，即使它没有显式地包含return一词
