Vim/TeXShop integration

I like to edit my LaTeX documents in vim (with the VIM-LaTeX package), but for various reasons, I like to use TeXShop to actually compile and view the document. In TeXShop, make sure that the "Configure for External Editor" button is checked, and then quit it. Once you add the following lines to your ~/.vim/ftplugin/tex.vim file, you just have to hit Cmd-R for the document to automatically open in TeXShop, and compile. You can use everything else just as you would expect. It really works great.

" Run LaTeX through TexShop
function! SRJ_runLatex()
   if &ft != 'tex'
      echo "calling srj_runLatex from a non-tex file"
      return ''
   end

   "write the file
   :w

   let thePath = getcwd() . '/'. expand("%")

   let execString = 'osascript -e "tell app \"TeXShop\"" -e "set theDoc to open ((POSIX file \"'.thePath.'\") as alias)" -e "tell theDoc to latexinteractive" -e "end tell"'
   exec 'silent! !'.execString
   return ''
endfunction
no  <expr> <D-r> SRJ_runLatex()
vn  <expr> <D-r> SRJ_runLatex()
ino <expr> <D-r> SRJ_runLatex()

The <D-r> means that hitting Command-R will save and compile it. You can change it in the syntax of any of the other vim command shortcuts.

EDIT 3/24/2009: To make it compatible with 10.4, since apparently the "open" command does not return the opened document as it does in 10.5, change the osascript line to:

let execString = 'osascript -e "tell app \"TeXShop\"" -e "set theDoc to open ((POSIX file \"'.thePath.'\") as alias)" -e "try" -e "tell theDoc to latexinteractive" -e "on error" -e "set theDoc to front document" -e "tell theDoc to latexinteractive" -e "end try" -e "end tell"'

UPDATE 9/25/2011: I've switched from using TeXShop to Skim. See my new Vim-LaTeX/Skim scripts here
