【问题描述】：
我正在编写一个 AppleScript 来处理一些 MTS 文件。该脚本递归地遍历顶级文件夹“Volumes:G-Drive:video”的子文件夹。子文件夹排列在年份文件夹中，从 2005 年的名为“2005”的文件夹开始。脚本尝试迭代的第一个文件夹“2005”发生运行时错误。我怀疑这与我处理别名和文本的方式有关，但在这一点上我很难解决如何解决它。运行时的错误是这样的： 无法将 {alias "G-DRIVE:video:", "2005:"} 转换为整数类型。
我不知道在我的代码中，整数类型在哪里发挥作用，从而导致此错误。脚本编辑器并没有将我指向代码中运行时错误的位置，所以我也不知道如何找出是哪一行导致了这种情况。
set folderName to "Volumes:G-Drive:video" as alias
my processFolder("", folderName)
on processFolder(root, folderNameToProcess)
tell application "Finder"
set theItems to every file of folder (root & folderNameToProcess)
repeat with theFile in theItems
set Nm to name of theFile as text
set Ex to name extension of theFile
if Nm does not contain "-c" and Ex is "MTS" then
set NmMinusExt to my remove_extension(Nm)
set logMsg to "Deleting " & Nm
my logThis(logMsg)
tell application "Finder" to delete theFile
end if
end repeat
set theItems to every file of folder (root & folderNameToProcess)
repeat with theFile in theItems
set Nm to name of theFile as text
set Ex to name extension of theFile
--tell (info for theFile) to set {Nm, Ex} to {name, name extension}
if Nm contains "-c" and Ex is "MTS" then
set NmMinusExt to my remove_extension(Nm)
set shortNm to my remove_lastTwoCharacters(NmMinusExt)
set name of theFile to shortNm & ".MTS" as text
set logMsg to "Renaming " & Nm
my logThis(logMsg)
--set lastTwoLetters to characters (((length of Nm) - 2) as number) thru (((length of Nm) - 0) as number) of (Nm as text)
--if lastTwoLetters is "-c" then
--display notification lastTwoLetters
--end if
end if
end repeat
set theFolders to name of folders of folder (root & folderNameToProcess)
repeat with theFolder in theFolders
copy theFolder as string to TheFolderName
display notification "found folder named: " & TheFolderName
set firstChar to (text 1 thru 1 of TheFolderName)
if firstChar is not "." then
--display dialog (folderNameToProcess & TheFolderName & ":")
try
my processFolder(folderNameToProcess, TheFolderName & ":")
on error errStr number errorNumber
display dialog errStr
end try
end if
end repeat
end tell
return
end processFolder
on remove_extension(this_name)
if this_name contains "." then
set this_name to ¬
(the reverse of every character of this_name) as string
set x to the offset of "." in this_name
set this_name to (text (x + 1) thru -1 of this_name)
set this_name to (the reverse of every character of this_name) as string
end if
return this_name
end remove_extension
on remove_lastTwoCharacters(this_name)
set this_name to ¬
(the reverse of every character of this_name) as string
set this_name to (text 3 thru -1 of this_name)
set this_name to (the reverse of every character of this_name) as string
return this_name
end remove_lastTwoCharacters
脚本编辑器的事件窗格产生以下跟踪：
tell application "Finder"
get every file of folder "G-DRIVE:video:"
get every file of folder "G-DRIVE:video:"
get name of every folder of folder "G-DRIVE:video:"
display notification "found folder named: 2005"
end tell
tell application "Script Editor"
display notification "found folder named: 2005"
end tell
tell application "Finder"
get every file of folder {alias "G-DRIVE:video:", "2005:"}
display dialog "Finder got an error: Can’t make {alias \"G-DRIVE:video:\", \"2005:\"} into type integer."
