AppleScript每隔几分钟读取一次数据

标签: applescript handle idle-timer

我运行一个屏幕,在菜单栏上显示一些数据

变量取自"〜/ Desktop / _MyData.plist"

一切正常,但是当_MyData.plist

上的数据发生变化时

如何让脚本获取新数据?我想我们不能指望AppleScript检测文件更改,然后运行脚本,但有没有办法让plist数据处于空闲状态并保持运行整个脚本。

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

以下是整个脚本:

  use AppleScript version "2.4"
use scripting additions
use framework "Foundation"
use framework "AppKit"

property StatusItem : missing value
property selectedMenu : ""
property theDisplay : ""
property defaults : class "NSUserDefaults"
property internalMenuItem : class "NSMenuItem"
property externalMenuItem : class "NSMenuItem"
property newMenu : class "NSMenu"
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
end tell
if not (current application's NSThread's isMainThread()) as boolean then
    display alert "This script must be run from the main thread." buttons {"Cancel"} as critical
    error number -128
end if

on menuNeedsUpdate:(menu)

    my makeMenus()
end menuNeedsUpdate:

on makeMenus()

    newMenu's removeAllItems()

    repeat with i from 1 to number of items in someListInstances
        set this_item to item i of someListInstances
        set thisMenuItem to (current application's NSMenuItem's alloc()'s initWithTitle:this_item action:"someAction:" keyEquivalent:"")

        (newMenu's addItem:thisMenuItem)

        (thisMenuItem's setTarget:me) -- required for enabling the menu item
        if i is equal to 3 then
            (newMenu's addItem:(current application's NSMenuItem's separatorItem)) -- add a seperator
        end if
    end repeat

end makeMenus



on someAction:sender
    --MenuItem 
end someAction:

-- create an NSStatusBar
on makeStatusBar()
    set bar to current application's NSStatusBar's systemStatusBar

    set StatusItem to bar's statusItemWithLength:-1.0

    -- set up the initial NSStatusBars title
    StatusItem's setTitle:(theAccountNumberFromPlist & " " & thename & " " & fullEmail & " " & SNNumber & " " & appName)
    -- set up the initial NSMenu of the statusbar
    set newMenu to current application's NSMenu's alloc()'s initWithTitle:"Custom"

    newMenu's setDelegate:me (*


    *)

    StatusItem's setMenu:newMenu

end makeStatusBar

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。这是essential part from apples docs

  

空闲并退出保持开放式应用程序的处理程序

     

默认情况下,接收运行或打开命令的脚本应用程序   处理该单个命令然后退出。相比之下,保持开放   脚本应用程序(保存为在脚本编辑器中保持打开状态)保留   它启动后打开。

     

保持打开的脚本应用程序可能有用,原因如下:

     
      
  • 保持打开的脚本应用程序可以接收和处理其他命令   除了跑步和开放。这允许您使用脚本应用程序   作为脚本服务器,当它运行时,提供一个集合   可以由任何其他脚本调用的处理程序。

  •   
  • 保持打开的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。

  •   
     

经常保留开放脚本应用程序的两个特定处理程序   提供了一个空闲的处理程序和一个退出处理程序。

     

空闲处理程序

     

如果保持打开的脚本应用程序包含空闲处理程序,   AppleScript定期发送脚本应用程序空闲命令   默认值,每30秒 - 允许它执行后台任务   它没有执行其他操作。

     

如果空闲处理程序返回正数,则该数字成为   调用处理程序的速率(以秒为单位)。如果处理程序   返回非数字值,不更改速率。你可以返回0   保持默认延迟30秒。

     

例如,当保存为保持打开的应用程序时,以下内容   脚本每5秒发出一声哔声:

     

闲置时    哔
   返回5
  结束闲置

     

从处理程序返回的结果只是最后一个语句的结果,即使它没有明确包含单词return。
