How to customize the heading definition in org-mode

How to customize the heading definition in org-mode

Hello,

I want to use a lisp file (the .emacs file) in org-mode. This will help me to navigate through sections of the .emacs configuration file.
To do this I will need to customize the heading and change it from '*' to e.g. ';' (or else my .emacs file will fail to load.)

I noticed that in outline-mode there is an option to customize the heading definition.
I looked for an equivalent to this in org-mode but couldn't find a way to customize the heading definition.
Is there a way to do so?

Regards,

Avner Moshkovitz

I do so with the following setup:

I have a minimal init.el file in my ~/.emacs.d directory.
It basically looks like this:

--8<---------------cut here---------------start------------->8---
(require 'cl)

;; Load Path to org and babel
(setq load-path (cons "path/to/elisp/org-latest/lisp" load-path))
(setq load-path (cons "path/to/elisp/org-latest/contrib/lisp" load-path))
(setq load-path (cons "path/to/elisp/org-latest/contrib/babel/lisp" load-path))

;; modules got to be set _before_ org is loaded
(setq org-modules '(org-bbdb org-bibtex org-gnus org-info org-jsinfo 
                    org-irc org-vm org-w3m org-crypt org-learn
                    org-collector org-habit org-depend org-timer))

;; load up Org-mode and Org-babel
(require 'org)
;;(require 'org-babel-init)

;; Load my .emacs
(org-babel-load-file "path/to/emacs.org")
--8<---------------cut here---------------end--------------->8---

That last org-babel-load-file bit actually loads my other settings.
(see http://memnon.sdf-eu.org/emacs.html
     http://memnon.sdf-eu.org/emacs.org for an example)

AFAIK, the * is a fixed part of the org syntax and is not customizable.

Yes, there was a discussion here not so long ago - the result of the
discussion was (and I'm only paraphrasing) "It's true there is no way to
change it, and we're intentionally keeping it that way to prevent
needless complexity in org-mode".

But for this specific need (organizing the Emacs configuration with
org-mode), there is really no need for changing the headline
definition. You instead change your Emacs configuration to 'real' org-mode
files with the actual configuration inside Emacs-lisp src blocks. This is
much more powerful. As Memnon Anon mentioned, you only need a minimal
configuration in your init.el file and the rest can go all in one or more
org files that you load with org-babel-load-file.

I have converted my configuration to an org-mode file a good time ago and I
can tell you it is VERY worth the time invested. You can benefit from all
org-mode features. What org-babel-load-file does is tangling all of the
Emacs-lisp src blocks (only emacs-lisp blocks) to an Emacs lisp file and
then load that file. The org-babel-load-file function is smart enough to
only tangle the org file if something has changed. Therefore the delay
caused by the tangle process only happens when you change something.

A bonus side effect of this tangling process is that you can disable a
whole part of your Emacs configuration easily simple by setting the
'TANGLE' property of a headline containing the source blocks you want to
disable to 'no'.
