[CEDET-devel] Re: [cedet-semantic] auto-showing c/c++ function argument list

[Alex Ott <ott@je...>]

Hello

you can take c-mode-addon package, that can show help for c functions,
extracted from man pages.

Re: [CEDET-devel] A flexible `define-overload'

Hi Eric,

Thanks!

> Please check it in.  Then we can start using it.

I committed these changes in semantic-fw.el and semantic-idle.el

2004-04-20  David Ponce  <david@...>

	* cedet/semantic/semantic-fw.el

	(semantic-make-obsolete-overload)
	(semantic-obsolete-overload): New function.
	(semantic-fetch-overload): Handle obsoleted overloads.
	(semantic--override, semantic--expand-overrides)
	(semantic--overload-body): New functions.
	(define-overload): Use them.
	(semantic-fw-font-lock-keywords): Add
	`semantic-make-obsolete-overload'.

	* cedet/semantic/semantic-idle.el

	(semantic-idle-summary-current-symbol-info): New overload.
	(eldoc-current-symbol-info): Obsoleted by above overload.
	(semantic-idle-summary): Use above new overload.

We can now start to update overload code to use the new features ;-)

Great stuff.  You leave me little choice but to provide no criticisms.

Please check it in.  Then we can start using it.
