Automator中的持久变量存储

Question

是否可以在自动机工作流程中存储持久值（特别是服务流程）？似乎常规自动机变量are not persistant并尝试使用applescript chunk which has a property（通常是持久的）并不会实际上在Applescript中保留该属性（在测试中有效，但是当您运行服务时价值不会持续）。有什么想法吗？

您可以使用脚本对象将数据存储在不受影响的地方。

on run
    -- Path of script which holds data
    set thePath to (path to desktop as text) & "myData.scpt"
    --set thePath to (path to preferences as text) & "myData.scpt" -- better

    script theData
        property xxx : missing value
    end script

    try
        set theData to load script file thePath
    on error
        -- On first run, set the initial value of the variable
        set theData's xxx to 5
    end try

    -- change the value of the variable
    set theData's xxx to (theData's xxx) + 1

    -- save your changes
    store script theData in file thePath replacing yes
    return theData's xxx
end run
