I am trying write a script that runs when a PostScript file is generated by a DTP app (Quark or InDesign) into a watched folder.
The issue is that, if the PS file is large, the folder action will initiate the script before the PS file has completely generated and unless the Finder is asked to update the watched folder, it shows the same file size regardless of the interval.
Also because of the Finder updating issue, the user can be fooled into prematurely initiating the script manually if they see a .ps file in their Finder window even though generation has not yet finished.
Another issue, perhaps compounding all of this, is that the users work from a server partition to the HD and there can be server slow-downs at various times through the day.
Unless someone has a better idea for a workaround, what I would like to do is have the script reference the PS file size at different time intervals and then compare the intervals and, if the file sizes are different, repeat until they are the same size with a timeout.
Here’s an example of one of the scripts I’ve come up with so far. I don’t think the syntax is entirely correct.
Any help would be greatly appreciated.
tell application "Finder"
set Counter to 0
repeat
delay 2
repeat 5 times
update (get items of folder psFolder)
end repeat
set XpsFiles to ((items of folder psFolder) whose name extension is ("ps" as list))
set XselectionList to {(XpsFiles as list)}
set XselectedCount to count items in XselectionList
set XpsFile to ((first item of folder psFolder) whose name extension is ("ps"))
get physical size of XpsFile
delay 2
repeat 5 times
update (get items of folder psFolder)
end repeat
set YpsFiles to ((items of folder psFolder) whose name extension is ("ps" as list))
set YselectionList to {(YpsFiles as list)}
set YselectedCount to count items in YselectionList
set YpsFile to ((first item of psFolder) whose name extension is ("ps"))
get physical size of YpsFile
if physical size of XpsFile is not equal to physical size of YpsFile then
with timeout of 120 seconds
repeat until (physical size of XpsFile is equal to physical size of YpsFile) is false
end repeat
end timeout
if physical size of XpsFile is equal to physical size of YpsFile then
set Counter to Counter + 1
if Counter is 2 then
end if
end if
end if
end repeat
end tell
