Didn't want to totally waste my weekend, I wrote a simple AppleScript
for this task. I know not much about AppleScript, so it is for sure
there's much to be improved. I would also appreciate any comments.



This script, when saved as compiled application with no Start up
screen, will be invoked by double clicks. You will be asked asks to
choose the source file, the modified file (i.e., 2 files), and the
folder in which you want the comparison result to be saved. The
default name is diff.tex. It then is passed to TeXShop and opens by

Prerequisite: You need to have latexdiff installed. 

Note: I think the script is quite self-evident. You are welcome to
modify according to your setup.


property diffFile : "diff.tex"
set theFile to (choose file with prompt "Select the source file:")
set sourcePath to quoted form of POSIX path of theFile
set newFile to (choose file with prompt "Select the modefied file:")
set modefiedPath to get quoted form of POSIX path of newFile
set theFolder to (choose folder with prompt "Where to save diff file?")
set targetPath to POSIX path of theFolder
do shell script "/usr/local/bin/latexdiff " & sourcePath & " " &
modefiedPath & ">" & (quoted form of (targetPath & diffFile))

set macPath to POSIX file (targetPath & diffFile)
tell application "TeXShop"
		open macPath
	end try
end tell
