source code folding

source code folding

[Petro Khoroshyy]

Hi all.
I can fold source code block using TAB key on begin_src block. Is there
a shortcut to do it within source code block, without navigation to
begin_src line?
Thanks.
Petro.

I'm not sure there's such a short cut, but you can define one for yourself.

A simple function (without any sort of error checking) like the one
below can be bound to a key-binding of your choice.

------------------------------------------------------------------------
(defun my/collapse-src-block ()
  "Collapses a source block when called from inside a block."
  (interactive)
  (org-babel-goto-src-block-head)
  (org-cycle))
------------------------------------------------------------------------

Hope that helps,
Puneeth

org-narrow-to-block should do it when modified slightly:

#+begin_src emacs-lisp
(defun my-org-toggle-current-block ()
  "Un-/Collapses a block when called from inside a block."
  (interactive)
    (let* ((case-fold-search t)
	   (blockp (org-between-regexps-p "^[ \t]*#\\+begin_.*"
					 "^[ \t]*#\\+end_.*")))
    (if (not blockp) 
	(message "Not in a block")
      (goto-char (car blockp))
      (org-cycle))))
#+end_src

Thanks all.
This is exactly what I need.

Hi Petro,

Such functionality is not provided by default, but the
`org-hide-block-toggle' command does perform this action, and you could
assign it a keybinding in your personal config to make it easy to call.

Best,
