To typeset documents I use pdflatex. I edit my tex files using vim and build the pdfs using a makefile. At the end of my make sequence I like to have:
Which on my mac causes preview to open my pdf document.
When I recompile and this command runs, sometimes preview just focuses the already open document, but other times it opens a new window. I haven’t backwards engineered how it decides which to do, but it might be correlated with the amount of change in between. In any case, Preview recently has been crashing when it tries to open the same document in a new window. For small, short-term articles this is not so annoying. But now, writing my t****s, I’m really getting frustrated.
I wrote an applescript to replace the
open command above. First you’ll need to enable applescript for Preview.app. Then you can save the following in preview.scpt.
on run argv set file_name to item 1 of argv try tell application "Preview" activate set open_already to false repeat with this_doc in every document set open_already to open_already or (name of this_doc as string is equal to file_name) if open_already then return "open already" end if end repeat if not open_already then open (do shell script "pwd") & "/" & file_name return "" end if end tell on error errMsg return errMsg end try end run
You can run with:
osascript preview.scpt my.pdf
The rerun to see that no action is taken.
