UPDATE: I've updated the script so that it works with OS/X Leopard. See comments for details.The OS X PDF viewer Skim has the ability to automatically refresh files after they have been updated on disk. In Skim version 0.4.1 and below, this was done by polling a file every second to see if it has been changed. In Skim version 0.5 and up, this feature is implemented using kqueue events. This is a much better way of doing things. However, if the file that is open gets deleted and a new file created with the same name, events for that new file will not be received by Skim.
Unfortunately, the script simpdftex that comes with a number of LaTeX distributions (e.g., gwTeX) deletes a PDF before updating it. This means that autorefreshes won't work when regenerating a PDF from its LaTeX source using simpdftex.
So, motivated by the history in a Skim bug report, I've put together a simpdftexnodel script that fixes this problem (based on the 2007/05/07 gwTeX simpdftex). To use this file:
- Place the script somewhere (probably in your PATH).
- chmod the file 0755.
- Make sure that your distillers and TeX program (or at least symlinks to them) exist in the same directory.
- Stop using simpdftex and start using simpdftexnodel.
