how to use built in cedet in emacs 23.3?

Question

I am using emacs 23.3

I heard that emacs 23.3 include cedet by default

but how can I use them? how should I change my ".emacs" file for ..

1. function parameter hint (when I type "malloc(" then parameter hint arise somewhere)
2. auto complete menu (when there are variable "qwer", "qwert", and "qwerty" and when I type "qwe" then those 3 selectable hint arise somewhere)

when I edit c or cpp file?

(and.. any suggestion for cedet feature?)

Answer 1

Are you asking as someone using an old CEDET distribution, or someone new to CEDET? I'll assume the later.

First, you need to enable semantic with this in your .emacs:

(semantic-mode 1)

next, if your project is particularly large (more than 1 directory full of files) you will need to enable EDE.

(global-ede-mode 1)

and figure out what kind of project to use. Your project might be auto-detected if it is one of the common ones, otherwise you should create one of type ede-cpp-root to just wrap that directory, or try enabling the generic project types that use a Makefile, scons or cmap, or with:

(ede-enable-generic-projects)

Generic projects can sometimes get in the way, so they are disabled by default.

You would then need to enable the idle summary mode:

(global-semantic-idle-summary-mode 1)

Look in the Development menu for other options.
