    (require 'yasnippet) ;; not yasnippet-bundle
    (yas/initialize)
    (yas/load-directory "~/.emacs.d/yasnippet/snippets")
   
    ;; scala-mode
    (add-to-list 'load-path "~/.emacs.d/scala-mode")
    (require 'scala-mode-auto) ;; 编辑.scala文件时自动启动scala mode
   
    ;; scala yasnippet
    (setq yas/my-directory "~/.emacs.d/scala-mode/contrib/yasnippet/snippets")
    (yas/load-directory yas/my-directory)
    (add-hook 'scala-mode-hook
                '(lambda ()
                   (yas/minor-mode-on)
                   ))
                  
    ;; scala-ensime
    (add-to-list 'load-path "~/.emacs.d/ensime/elisp")
