Re: Helo for defun/macro arguments list in minibuffer when in org-babel src blocks?

[Tim Cross <theophilusx@gmail.com>]

Hi,

when you are editing source blocks are you using org-edit-special, 
normally
bound to C-c ') or are you just editing the source blocks directly 
within the
org buffer?

The functionality you are referring to sounds like eldoc minor 
mode.

If you open a dedicated buffer to edit a file in the same language 
as your
source blocks, do you see the behaviour you want. For example, 
open a file
called test.el and edit some Emacs lisp. If you don't see the 
behaviour your
after, you need to configure emacs-lisp-mode to load eldoc mode. 
Try typing M-x
eldoc-mode <ret> and see if you then get the behaviour your after. 
If you do,
then read up on eldoc-mode and how to enable it.

The environment you get with a dedicated buffer and that you get 
with
org-edit-special should be roughly the same. So the trick is to 
get things
working how you like them using a dedicated *.el buffer and then 
use
org-edit-special whenever you need to edit source blocks. There is 
also another
good reason to use org-edit-special - there are some situations 
where org needs
to add some special escaping characters in source blocks to enable 
things to be
parsed correctly. Using org-edit-special ensures this occurs when 
necessary.
Editing the source blocks directly does not.
