Connection invalid

Scripting Forums AppleScript | Mac OS X

Hi,

I have been working on a script to rename files in a target folder. Basically I wanted the script to repeat until all files were renamed using two automator apps for replacing text in the filename. The script worked the first couple of times and then when testing it with additional files I suddenly got “FLV_rename got an error: Connection is invalid”. I was wondering if anybody could sheet some light on this or have encountered this problem before?

here is the script:

set targetFolder to ((path to desktop) as string) & "TEST_FOLDER"
set blnAnswer to false
repeat while blnAnswer = false
	tell application "Finder"
		repeat with folderCounter from 1 to count of files in folder targetFolder
			set inputFiles to (name of file folderCounter of folder targetFolder) as string
			set outputFiles to (name of file folderCounter of folder targetFolder) as string
			if inputFiles contains "_01_001_110001_WMV" then
				tell application "WMV_rename"
					open inputFiles
				end tell
			else if inputFiles contains "_01_001_110001_FLV" then
				tell application "FLV_rename"
					open inputFiles
				end tell
			else if outputFiles contains "_od" or outputFiles contains "_640" then
				set blnAnswer to true
			end if
		end repeat
	end tell
end repeat

Also a couple of times this process forced Automator to quit with the following error log (not sure if it is any help)

Hi,

if you’re using AppleScript anyway, I recommend to do the rename tasks also with AppleScript!
Renaming a file in a repeat loop with the form


tell application "Finder"
	repeat with folderCounter from 1 to count of files in folder targetFolder
		set inputFiles to (name of file folderCounter of folder targetFolder) as string
		set outputFiles to (name of file folderCounter of folder targetFolder) as string
		
	end repeat
end tell

can cause an error (and is very slow), because you retrieve the list in each iteration,
and the renaming can change the order of the files.
A better form is


tell application "Finder"
	repeat with oneFile in (get files in folder targetFolder)
		set inputFiles to name of oneFile
		set outputFiles to name of oneFile
		
	end repeat
end tell

the list is only retrieved once

Hi Stefan,

Thank you for the quick reply. You are spot on with your suggestion on a quicker process. I used Automator because the replace text function is so well defined and I thought it would be easier (clearly not)

Admittedly I still get connection error using the “oneFile” method but I will try and work out how to replace text in the file using applescript.

Again thank you.

Jonathan
