[置顶]Emacs C++智能提示

Emacs中的C++程序智能提示是个不容易的活。我使用的是auto-completion插件。该插件依赖clang编译器进行代码分析，当然还依赖其他的emacs插件。下面是我的Emacs配置文件。

;;------------------------------------------------------------------------------ ;; auto complete ;;------------------------------------------------------------------------------ ;;(load-file (expand-file-name "/opt/emacs_plugins/c++/auto-complete-1.3.1") ;;(add-to-list 'load-path "/opt") ;;(require 'auto-complete-config) ;;(add-to-list 'ac-dictionary-directories "/opt/ac-dict") ;;(ac-config-default) (add-to-list 'load-path "/opt/emacs_plugins/c++/auto-complete-1.3.1") (require 'auto-complete-config) (add-to-list 'ac-dictionary-directories "/opt/ac-dict") ;;------------------------------------------------------------------------------ ;; yasnippet ;;------------------------------------------------------------------------------ ;;sudo apt-get install yasnippet (add-to-list 'load-path "/opt/emacs_plugins/c++") (add-to-list 'ac-dictionary-directories "/opt/emacs_plugins/c++") (require 'yasnippet-bundle) ;;------------------------------------------------------------------------------ ;; clang for c++ ;;------------------------------------------------------------------------------ (load-file "/opt/emacs_plugins/c++/brianjcj-auto-complete-clang-9db79f4/auto-complete-clang.el") (require 'auto-complete-clang) (setq ac-auto-start nil) (setq ac-quick-help-delay 0.5) (define-key ac-mode-map [(control tab)] 'auto-complete) (defun my-ac-config () (setq ac-clang-flags (split-string "-I/usr/local/gcc-4.6.1/include/c++/4.6.1 -I/usr/src/boost_1_47_0")) (setq-default ac-sources '(ac-source-abbrev ac-source-dictionary ac-source-words-in-same-mode-buffers)) (add-hook 'emacs-lisp-mode-hook 'ac-emacs-lisp-mode-setup) ;;(add-hook 'c-mode-common-hook 'ac-cc-mode-setup) (add-hook 'ruby-mode-hook 'ac-ruby-mode-setup) (add-hook 'css-mode-hook 'ac-css-mode-setup) (add-hook 'auto-complete-mode-hook 'ac-common-setup) (global-auto-complete-mode t)) (defun my-ac-cc-mode-setup () (setq ac-sources (append '(ac-source-clang ac-source-yasnippet) ac-sources))) (add-hook 'c-mode-common-hook 'my-ac-cc-mode-setup) ;; ac-source-gtags (my-ac-config)

需要提示的时候，就按下Ctrl+Tab键。
