Emacs for browsing c code

Emacs for browsing c code

[Daniel (Youngwhan)]

Hi,

I really like Emacs to edit and browse a c/c++ code with cscope so
far. I have used CEDET and ECB, but they were too complicated and not
for me at this time. So, I decided to use cscope only.

However, one of what I miss features is browsing function names in a
certain window. Source Insight / Eclipse or other tools supports that
when a function name is clicked in a certain window, it jumps to the
position.

I tried to google, but no luck to find it.

Does anybody know that kind of feature is possible in emacs not using
CEDET/ECB to make simple?

Thanks,

Daniel

You should be able to do that using a tags file and speedbar.

I am addicted to cscope as well. I don't know if it is what you're
looking for, but below are my xcscope.el configurations.

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;;
;;; C Mode
;;;

(defun my-c-mode ()
  (interactive)
  (hide-ifdef-mode)
  (c-set-style "bsd")
  (setq
   indent-tabs-mode t
   tab-width 4
   c-basic-offset 4
   c-backslash-max-column fill-column
   c-backslash-column c-backslash-max-column)
  ;; Cscope Bindings
  (define-key c-mode-map (kbd "C-c . i") 'cscope-find-files-including-
file)
  (define-key c-mode-map (kbd "C-c . f") 'cscope-find-called-
functions)
  (define-key c-mode-map (kbd "C-c . c f") 'cscope-find-functions-
calling-this-function)
  (define-key c-mode-map (kbd "C-c . g") 'cscope-find-global-
definition)
  (define-key c-mode-map (kbd "C-c . s") 'cscope-find-this-symbol)
  (define-key c-mode-map (kbd "C-c . t") 'cscope-find-this-text-
string)
  (define-key c-mode-map (kbd "C-c . x") 'cscope-index-files))

(add-hook 'c-mode-hook 'my-c-mode)

;;; xcscope.el

(load "~/elisp/xcscope.el")
(require 'xcscope)

It doesn't provide a separate window for stuff, but I'm happy with "C-
x 0", "C-x 1", "C-x 2", "C-x 3", and "C-x b" so far. I hope it works
for you as well.


Regards.

Thanks Guys,

Speedbar is sort of working for me at this time. :)

Thank you!

In vanilla Emacs, imenu and tags (a tags file) are good ways to navigate to
function etc. definitions.

If you use Icicles, then you can use both of them with completion in various
ways. And you can use imenu across multiple files or buffers (vanilla imenu is
single-buffer).

Thank you for the suggest, Drew.

I will take a look.

Thank you!
