How to auto hide all functions when open a source file

How to auto hide all functions when open a source file

[Ke Lu]

Hi,

I use emacs to edit c/c++/java/php files.
Is there any way to auto hide all functions when I open  a source file.
For example,It hope it looks like
Class XXX {
   var v1 = "a";
   var v2 = "b";

   function f1 ..
   function f2 ..

}
I would like it can automatic be done,not by  hs-hide-block,etc.

Adding this code snippit to your .emacs .

(add-hook 'hs-minor-mode-hook '(lambda () (hs-hide-all)))

will do an auto hs-hide-all when you open a file that uses hs-minor-mode.
However, it will also hide the classes' bodies, as well as any inline code.

There might be a way to stop the hiding of the bodies, but I'm not sure what it is.

   (add-hook 'hs-minor-mode-hook '(lambda () (hs-hide-all)))

The hideshow.el commentary sez:

;; Some languages (e.g., Java) are deeply nested, so the normal behavior
;; of `hs-hide-all' (hiding all but top-level blocks) results in very
;; little information shown, which is not very useful.  You can use the
;; variable `hs-hide-all-non-comment-function' to implement your idea of
;; what is more useful.  For example, the following code shows the next
;; nested level in addition to the top-level:
;;
;;   (defun ttn-hs-hide-level-1 ()
;;     (hs-hide-level 1)
;;     (forward-sexp 1))
;;   (setq hs-hide-all-non-comment-function 'ttn-hs-hide-level-1)

This was suggested a hideshow user; i haven't tested it personally.
