macvim-skim-install.sh is my install script for using MacVim.app with Skim.app. The agpy wiki page has instructions that are probably more clear; I don't really like the colorscheme / layout of this blog. You can use synctex to make an editor and viewer work together, but it is far from easy and far harder than it should be. Forward-search is pretty easy, but the latex-suite \ls only works intermittently and is not easily customizable. I had to do the following: For VIM->Skim.app (Skim.app is necessary for any of this to work), add these commands to .vimrc:

" Activate skimmap ,v :w<CR>:silent !/Applications/Skim.app/Contents/SharedSupport/displayline -r <C-r>=line('.')<CR> %<.pdf %<CR><CR>map ,p :w<CR>:silent !pdflatex -synctex=1 --interaction=nonstopmode %:p <CR>:silent !/Applications/Skim.app/Contents/SharedSupport/displayline -r <C-r>=line('.')<CR> %<.pdf %<CR><CR>map ,m :w<CR>:silent !make <CR>:silent !/Applications/Skim.app/Contents/SharedSupport/displayline -r <C-r>=line('.')<CR> %<.pdf %<CR><CR>" Reactivate VIMmap ,r :w<CR>:silent !/Applications/Skim.app/Contents/SharedSupport/displayline -r <C-r>=line('.')<CR> %<.pdf %<CR>:silent !osascript -e "tell application \"MacVim\" to activate" <CR><CR>map ,t :w<CR>:silent !pdflatex -synctex=1 --interaction=nonstopmode %:p <CR>:silent !/Applications/Skim.app/Contents/SharedSupport/displayline -r <C-r>=line('.')<CR> %<.pdf %<CR>:silent !osascript -e "tell application \"MacVim\" to activate" <CR><CR>

The ,m command will reload the file and put your cursor where the text is. ,t will return VIM to the front afterwards. Going the other way (reverse-search / inverse-search) was MUCH more challenging. The code that does this is on agpy. Reproduced here for posterity (I hope to update the agpy version to deal with tabs). [A few hours later, I HAVE replaced the code. Below are the old applescript version, then the new, vim-based version #!/bin/bashfile="$1"line="$2"[ "${file:0:1}" == "/" ] || file="${PWD}/$file"# Use Applescript to activate VIM, find file, and load it# the 'delay' command is needed to prevent command/control/shift from sticking when this# is activated (e.g., from Skim, where the command is command-shift-click)## key code 53 is "escape" to escape to command mode in VIMexec osascript \-e "delay 0.2" \-e "tell application \"MacVim\" to activate" \-e "tell application \"System Events\"" \-e "  tell process \"MacVim\"" \-e "    key code 53 "\-e "    keystroke \":set hidden\" & return " \-e "    keystroke \":if bufexists(bufname('$file'))\" & return " \-e "    keystroke \":exe \\\":buffer \\\" . bufnr(bufname('$file'))\"  & return " \-e "    keystroke \":else \" & return " \-e "    keystroke \":echo \\\"Could not load file\\\" \" & return " \-e "    keystroke \":endif\" & return " \-e "    keystroke \":$line\" & return " \-e "  end tell" \-e "end tell" New code: download link A

Save that as an executable in your default path (e.g., /usr/local/bin/macvim-load-line) and open Skim.app, go to Preferences:Sync and make the command look like this:

You need to have mvim on your path. mvim comes with MacVim.app, but is NOT installed by default. Install it by doing something like: `` cp /Users/adam/Downloads/MacVim-7_3-53/mvim /usr/local/bin/mvim `` You'll also need to install WhichTab.vim in your ~/.vim/plugins/ directory. It's available here (download link B). Here's the source:
