Ответ @garyjohn правильный.
и позвольте мне добавить пример того, как запустить несколько компиляции на Coffeescript:
# add these lines to your .vimrc file (~/.vimrc in my pc)
autocmd BufWritePost,FileWritePost *.coffee :silent !coffee --compile --join appstore/static/javascripts/angular/controllers.js file1.coffee file2.coffee
autocmd BufWritePost,FileWritePost *.coffee :silent !coffee --compile appstore/static/javascripts/angular/app.coffee appstore/static/javascripts/angular/directives.coffee appstore/static/javascripts/angular/filters.coffee appstore/static/javascripts/angular/services.coffee
