[OS X TeX] Applescript fot BBEit+TeXShop+pdfsync

[Claus Gerhardt]

Below is an Applescript for people using BBEdit as editor. The tex file 
has to be a TeXShop file, but it can be opened, saved and edited in 
BBEdit.

The script runs pdflatex - or a shell script of your choice - and 
catches any latex errors for BBEdit. If there are no errors, then it 
tells TeXShop  to open resp. refresh the tex file, tpyesetting it 
again, and putting the cursor in the same line as it was in BBEdit. 
That way you can use pdfsync. If you don't want pdfsync, then the 
typesetting part in TeXShop can be commented, or you can use an altered 
  copy of the script.

When I tested the script, TeXShop's preferences weren't set for 
external editor - only the preview update was checked.

My TeX-Scripts-BBEdit should be installed.
