Using CEDET and ECB with Emacs
(I tested the following procedure about installing and customizing CEDET for Emacs with GNU Emacs 23 under Ubuntu and Snow Leopard.)


Installation


Install CEDET
Download the source package of CEDET
Unpack to ~/.emacs.d/cedet (or other places)
Compile the package using command
1
emacs -Q -nw -l cedet-build.el -f cedet-build -f save-buffers-kill-terminal
Install external tag systems (optionally required by CEDET)
GNU Global, and/or
exuberent ctags
Install ECB
Download the source package of ECB.
Unpack into ~/.emacs.d/ecb (or any other directory)
Customization


An excellent tutorial about customizing CEDET is here. The author also published his .emacs file which contains a few flaws. Mine based on his is as follows:

;; CEDET(load-file "~/.emacs.d/cedet-1.0pre7/common/cedet.el") (global-ede-mode 'nil)                  ; do NOT use project manager (semantic-load-enable-excessive-code-helpers) (require 'semantic-ia)          ; names completion and display of tags(require 'semantic-gcc)         ; auto locate system include files (semantic-add-system-include "~/3rd-party/boost-1.43.0/include/" 'c++-mode)(semantic-add-system-include "~/3rd-party/protobuf-2.3.0/include" 'c++-mode) (require 'semanticdb)(global-semanticdb-minor-mode 1) (defun my-cedet-hook ()  (local-set-key [(control return)] 'semantic-ia-complete-symbol)  (local-set-key "\C-c?" 'semantic-ia-complete-symbol-menu)  (local-set-key "\C-c>" 'semantic-complete-analyze-inline)  (local-set-key "\C-c=" 'semantic-decoration-include-visit)  (local-set-key "\C-cj" 'semantic-ia-fast-jump)  (local-set-key "\C-cq" 'semantic-ia-show-doc)  (local-set-key "\C-cs" 'semantic-ia-show-summary)  (local-set-key "\C-cp" 'semantic-analyze-proto-impl-toggle)  (local-set-key "\C-c+" 'semantic-tag-folding-show-block)  (local-set-key "\C-c-" 'semantic-tag-folding-fold-block)  (local-set-key "\C-c\C-c+" 'semantic-tag-folding-show-all)  (local-set-key "\C-c\C-c-" 'semantic-tag-folding-fold-all)  )(add-hook 'c-mode-common-hook 'my-cedet-hook) (global-semantic-tag-folding-mode 1) (require 'eassist) ;(concat essist-header-switches ("hh" "cc"))(defun alexott/c-mode-cedet-hook ()  (local-set-key "\C-ct" 'eassist-switch-h-cpp)  (local-set-key "\C-xt" 'eassist-switch-h-cpp)  (local-set-key "\C-ce" 'eassist-list-methods)  (local-set-key "\C-c\C-r" 'semantic-symref)  )(add-hook 'c-mode-common-hook 'alexott/c-mode-cedet-hook) ;; gnu global support(require 'semanticdb-global)(semanticdb-enable-gnu-global-databases 'c-mode)(semanticdb-enable-gnu-global-databases 'c++-mode) ;; ctags(require 'semanticdb-ectag)(semantic-load-enable-primary-exuberent-ctags-support) (global-semantic-idle-tag-highlight-mode 1)

Using CEDET


control return: whatever the symbol you are typing, this hot key automatically complete it for you.
C-c?: another way to complete the symbol you are typing
C-c>: when you typed . or -> after an object name, use this key to show possible public member functions or data members.
C-cj: jump to the definition of the symbol under cursor
C-cs: show a summary about the symbol under cursor
C-cq: show the document of the symbol under cursor
C-c=: visit the header file under cursor
C-cp: toggle between the implementation and a prototype of symbol under cursor
C-ce: when your cursor is in the scope of a class or one of its member function, list all methods in the class
C-cC-r: show references of the symbol under cursor
C-cC-c-: fold all
C-cC-c+: unfold all
C-c-: fold the block under cursor
C-c+: unfold the block under cursor
Using ECB


Once CEDET is installed and customized, we can use ECB. Add the following lines into your .emacs file:

(add-to-list 'load-path "~/.emacs.d/ecb-2.40")(require 'ecb)(require 'ecb-autoloads)

In Emacs, we can use M-x ecb-activate to turn on ECB mode. This page shows how to byte compile ECB to make it runs fast.
