emacs 自带的代码补全配置

网上找的，花了好长时间，发觉网上大部分是用cedet的，自带的这个介绍的很少。。。

在.emacs中设置如下

;;设置检索范围
(setq semanticdb-project-roots
(list
(expand-file-name "/")));;可以设置为项目的顶级目录


;;绑定按键,ctr+tab,以下三种,任意选择一个,我喜欢第二个
;;(global-set-key [(control tab)] 'senator-complete-symbol);
(global-set-key [(control tab)] ' senator-completion-menu-popup)
;; (global-set-key [(control tab)] 'semantic-ia-complete-symbol-menu)




(global-set-key [(meta ?/)] 'hippie-expand)


(setq hippie-expand-try-functions-list
      '(try-expand-dabbrev
 try-expand-dabbrev-visible
 try-expand-dabbrev-all-buffers
 try-expand-dabbrev-from-kill
 try-complete-file-name-partially
 try-complete-file-name
 try-expand-all-abbrevs
 try-expand-list
 try-expand-line
 try-complete-lisp-symbol-partially
 try-complete-lisp-symbol))
