[OS X TeX] PDF syncing from an external editor to TeXShop

[tkiffe]

Howdy y’all,

I am using the following minimal Apple Script to sync from a source file to a PDF file in TeXShop:

set texfile to "/Users/tkiffe/Documents/textests/gentle.tex"
set pdffile to "/Users/tkiffe/Documents/textests/gentle.pdf"
set syncfile to "/Users/tkiffe/Documents/textests/gentle.synctex.gz"
tell application "/Applications/TeX/TeXShop.app"
	try
		sync_to_preview pdffile theIndex 1 theLine 1992 theName texfile
	on error
		display dialog "help"
	end try
end tell

The values of the parameters theIndex, theLine, and theName were obtained through BBEdit and are valid.
When I run the script with gentle.pdf displayed in TeXShop, I get no error messages and nothing happens to the pdf file. I don’t know what the object of the sync_to_preview command should be. I have tried the pdf file, the tex file, and even the synctex.gz file. None of them work. TeXShop’s Applescript dictionary simply states

sync_to_preview: object of the command

which is not very helpful.

Here is a minimal example of an apple script which successfully typesets a file in TeXShop and displays the resulting pdf file

set texfile to "/Users/tkiffe/Documents/textests/gentle.tex"
tell application "/Applications/TeX/TeXShop.app"
	activate
	open texfile
end tell


In this case it is obvious that the object of the open command is the file to open. It is not obvious to me what the object of the sync_to_preview command should be. This applies to all 4 sync commands in TeXShop’s Applescript dictionary. Any help would be greatly appreciated.

TIA,
Tom
