Vim and TiAlloy: automatically open view and styles when opening controller (plus other styling)

.vimrc

function OpenAlloy()
  let s:view=substitute(expand('%:r'),"controllers","views","").".jade" 
  let s:style=substitute(expand('%:r'),"controllers","styles","").".tss" 
  exec '80vsp' s:style 
  set filetype=javascript
  exec 'sp' s:view
  set filetype=jade
endfunction

if has('autocmd')
  au BufRead *.tss set filetype=javascript
  au BufRead */controllers/*.js call OpenAlloy()
  au BufRead *.jmk set filetype=javascript
endif

Updated so it works with widget controllers.
I'm using jade views. Change line 2 for xml...

Insert this between line 11 and 12 if you need it to open tabs for you:

   au BufAdd */controllers/*.js tabnew

I usually just open tabs from ctrl+p when opening controllers.
