Semantic & Autocomplete Usage

Semantic & Autocomplete Usage

[Les Harris]

Does anyone have any experience using AutoComplete.el
(http://www.emacswiki.org/emacs/AutoComplete) with semantic
as a source?

I am also using Auto-Complete-Extension.el 
(http://www.emacswiki.org/cgi-bin/emacs/auto-complete-extension.el)
which provides among other things ac-source-semantic.

My configuration in .emacs:

(require 'auto-complete)
(require 'auto-complete-extension) ; Provides ac-source-semantic
(global-auto-complete-mode t)

(define-key ac-complete-mode-map "\C-\M-n" 'ac-next)
(define-key ac-complete-mode-map "\C-\M-p" 'ac-previous)
(define-key ac-complete-mode-map "\t" 'ac-expand)
(define-key ac-complete-mode-map "\r" 'ac-complete)

<snip>

(add-hook 'c-mode-common-hook '(lambda ()
	(c-toggle-auto-state 1)
	(linum-mode)
	(set (make-local-variable 'ac-sources) 
                                  (append '(ac-source-semantic)))
;	(set (make-local-variable 'ac-candidate-function) (append
	'ac-semantic-candidate))
))

It apparently does nothing :)  When I uncomment the
ac-candidate-function line I get a syntax error:

Error in post-command-hook: (wrong-number-of-arguments (lambda (prefix) 
(if (memq major-mode (quote (c-mode c++-mode jde-mode java-mode)))
(prog1 (mapcar (quote semantic-tag-name) (ignore-errors (or
 (semantic-ia-get-completions (semantic-analyze-current-context) 
(point)) (senator-find-tag-for-completion 
(regexp-quote prefix)))))))) 0)

Which is from auto-complete-extension.el. Doesn't inspire confidence.

If I try running something like semantic-analyze-possible-completions on
the following:
pMyObject->
It will correctly list the members of that struct so I am confidant
semantic itself is working correctly.

So I'm stuck.  Anyone help at all would be very appreciated.

Thanks!

I wonder if this might work better.

(add-hook 'c-mode-common-hook '(lambda ()
	(c-toggle-auto-state 1)
 	(linum-mode)
 	(make-local-variable 'ac-sources)
        (setq ac-sources '(ac-source-semantic ;and optionally 
;ac-source-abbrev ac-source-words-in-buffer
))
                           

This looks more like a successful auto-complete setup I have, though for 
a different mode and with my own homegrown set of keywords.

Ps I contacted the developer of the auto-complete-extension package and 
he thinks the semantic functions do not work well, so that might be your 
problem.

You really went above and beyond the call of duty! I notice the semantic
functions in that package have since been removed.  The other listing
provided on the wiki also appears not to function.

So in the mean time I guess I will simply try to implement a functioning
ac-semantic-source.  I notice in the development version of AutoComplete
the author has semantic support in the todo section so if all else fails
I suspect time will fix this issue for me one way or the other.

Thank you for all your help!
