I would have thought hideshow minor mode is what is desired??
(info "(emacs)Hideshow")
Which however happens to have rather ridiculous keybindings
If you like org-mode style TAB and Shift-TAB here's a hack — barely tried out!!
------------------
;; Add to your init
;; To get Tab and Shift-Tab to behave as in org-mode
(defvar rusi/hs-hide nil "Current state of hideshow for toggling all.")
;;;###autoload
(defun rusi/hs-toggle-all () "Toggle hideshow all."
(interactive)
(setq rusi/hs-hide (not rusi/hs-hide))
(if rusi/hs-hide
(hs-hide-all)
(hs-show-all)))
(add-hook 'hs-minor-mode-hook
(lambda ()
(define-key hs-minor-mode-map (kbd "<backtab>") 'rusi/hs-toggle-all)
(define-key hs-minor-mode-map (kbd "<tab>") 'hs-toggle-hiding)))
(add-hook 'python-mode-hook 'hs-minor-mode)
(add-hook 'c-mode-hook 'hs-minor-mode)
(add-hook 'emacs-lisp-mode-hook 'hs-minor-mode)
;; etc
