Question

I combined org-mode with lisp-mode to achieve beautiful code folding in emacs for lisp code: lisp-orgi-mode.
Basically, I use ‘;’ instead of ‘*’ as the heading character. For comments, I just put a space before the ‘;’, making it ‘ ;’ so it doesn’t count as a heading…

However, doing the same thing with python-mode doesn’t work… Probably because the ‘#’ character used by python comments interferes with org-mode settings…

Anyone been able to combine the functionality successfully ?
I know people have combined python-mode with outline-mode (link), but ouline-mode isn’t as good as org-mode…

Edit: Got it working nicely with outline-magic: python-magic.el

I use hideshow-org (and a small introduction here) for this purpose, and I think it works really, really good.

These are some additional, but useful snippets:

(dolist (hook (list 'c-mode-common-hook
            'emacs-lisp-mode-hook
            'java-mode-hook
            'lisp-mode-hook
            'perl-mode-hook
            'sh-mode-hook))
  (add-hook hook 'my-hideshow-hook))

(defun my-hideshow-hook ()
  "thisandthat."
  (interactive)
  (progn (require 'hideshow-org)
     (global-set-key (kbd "C-c h") 'hs-org/minor-mode)
     (hs-org/minor-mode)))

(defadvice goto-line (after expand-after-goto-line activate compile)
  "hideshow-expand affected block when using goto-line in a collapsed buffer"
  (save-excursion
    (hs-show-block)))
