在AutoIT中将函数作为参数传递

Question

我有一些具有相同结构的功能(简化):

func moveFiles()  
    local $error = 1  
        For $i = 1 to 100
            updateProgress($i)  
            updateStatus("Processing " & $i & "/100 files")  
            $error *= moveFile($i)  
        Next  
    Return $error  
endFunc  

我想使这个像这样的通用函数:

func doSomething($function)  
    local $error = 1  
        For $i = 1 to 100
            updateProgress($i)  
            updateStatus("Processing " & $i & "/100 files")  

            $error *= $function($i)   ;execute the function that was passed

        Next  
    Return $error  
endFunc

所以我可以这样做:

doSomething($moveFiles)  
doSomething($compareFiles)
doSomething($removeFiles)
...

这是否可以在AutoIt v3中使用,我该怎么办？

挑战者出现了!有趣的问题.您可以通过内置Call​​调用函数名称作为字符串.例如,你有一个名为moveFiles的函数和一个参数,你可以调用该函数:

致电("moveFiles",$ i)

我写了一个例子来证明这一点.这是一种方便的简单方式来执行委托,事件或回调,因为您可能习惯使用其他严格的语言.在示例中,我故意省略错误处理,因为有两种方法可以做到这一点.您可以返回true/false(或1/0)值,也可以将SetError函数与@error宏一起使用.

以下是完整且有效的示例:

func doSomething($function)  
    local $error = 0
    For $i = 1 to 5
        updateProgress($i)  
        updateStatus("Processing " & $i & "/100 files")  

        Call($function, $i)
    Next  
    Return $error  
endFunc

doSomething("moveFiles")
doSomething("compareFiles")
;doSomething("removeFiles")

Func moveFiles($i)
    ConsoleWrite("Moving file " & $i & @CRLF)
EndFunc

Func compareFiles($i)
    ConsoleWrite("Copying file " & $i & @CRLF)
EndFunc

Func updateProgress($i)
    ConsoleWrite("Stage processing at #" & $i & @CRLF)
EndFunc

Func updateStatus($msg)
    ConsoleWrite($msg & @CRLF)
EndFunc

输出:

Stage processing at #1
Processing 1/5 files
Moving file 1
Stage processing at #2
Processing 2/5 files
Moving file 2
Stage processing at #3
Processing 3/5 files
Moving file 3
Stage processing at #4
Processing 4/5 files
Moving file 4
Stage processing at #5
Processing 5/5 files
Moving file 5
Stage processing at #1
Processing 1/5 files
Copying file 1
Stage processing at #2
Processing 2/5 files
Copying file 2
Stage processing at #3
Processing 3/5 files
Copying file 3
Stage processing at #4
Processing 4/5 files
Copying file 4
Stage processing at #5
Processing 5/5 files
