Hi everyone,
Is there a way for users to easily replace the leading stars with
another symbol? In particular, I want to replace the '*' with '#' so
that I use org mode to write pseduocode for R in outline form -- R
uses # to designate comments and this would ensure that the headers
wouldn't be read as code. I don't know emacs lisp (beyond cutting and
pasting to a .emacs file), but would be happy to dive in. Thanks!

I guess you want to use `orgstruct-mode' in R files, right? I also had
the idea to do that, but till now I failed. As a workaround I use
`outline-minor-mode' and set the `outline-regexp' to <comment-character
of the language><one-or-many-stars>.
Here's the code from my .emacs.
--8<---------------cut here---------------start------------->8---
(defun th-outline-regexp ()
"Calculate the outline regexp for the current mode."
(let ((comment-starter (replace-regexp-in-string
"[[:space:]]+" "" comment-start)))
(when (string= comment-start ";")
(setq comment-starter ";;"))
(concat "^" comment-starter "\\*+")))
(defun th-outline-minor-mode-init ()
(interactive)
(setq outline-regexp (th-outline-regexp)))
(add-hook 'outline-minor-mode-hook
'th-outline-minor-mode-init)
--8<---------------cut here---------------end--------------->8---
I wonder if I cannot make `orgstruct-mode' work the same way. I've
always thought that it uses `outline-regexp' for the cycling and stuff,
but maybe I'm wrong. What's the correct regexp that's used for
`org-cycle'? `org-complex-heading-regexp'?
Bye,

Hi Tassilo,
Thanks for the suggestion -- your code worked great when I loaded it
on its own, but seems to be in conflict with something else in my
.emacs file, so I'll have to tinker with it a little bit. This seems
like an okay temporary solution, but I may look into orgstruct proper
when I have some free time.
Best,

org-cycle does use outline-regexp, so this will work fine. However,
for much other functionality, including demotion and promotion,
stars are hard-coded.

Hm, it does work with "M-x org-cycle" (then it toggles between FOLDED
and CHILDREN, but not SUBTREE), but with TAB nothing happens.
,----
| <tab> runs the command orgstruct-hijacker-command-102, which is an interactive
| Lisp function.
|
| It is bound to <tab>.
|
| (orgstruct-hijacker-command-102 arg)
|
| In Structure, run `org-cycle'.
| Outside of structure, run the binding of `[(tab)]' or ` '.
`----
Here's the test file:
--8<---------------cut here---------------start------------->8---
;;* Heading 1
(setq foo 1)
;;** SubHeading 1.1
(+ 1 1) ;; test
;;** SubHeading 1.2
(defun foo () nil)
;;* Heading 2
(defun bar () nil)
;;** SubHeading 2.1
(+ 7 7)
--8<---------------cut here---------------end--------------->8---
When I hit C-c C-c which should allow setting tags, it tells me
org-ctrl-c-ctrl-c: C-c C-c can do nothing useful at this location.
although I'm on a headline and the value of outline regexp is:
,----
| outline-regexp is a variable defined in `outline.el'.
| Its value is ";;[*]+ "
| Local in buffer test.el; global value is "[*\f]+"
`----
The only thing that comes into my mind is that those hijacker commands
use a hardcoded outline-regexp or an earlier value of outline-regexp.
Yeah, that seems to be the case. When I use only stars, the key
bindings work.
Carsten, could you change that, so that the hijackers use the current
value of outline-regexp?
> However, for much other functionality, including demotion and

Cycling would be more than enough for me. I just want to have a good
structure in my code files where I can easily toggle the visibility.
Basically, `outline-minor-mode' does what I want, but org cycling is
still better.

Hi Tassilo,
you are right, it does not work with orgstruct-mode, because that sets
local variables like in Org-mode for the duration of the command.
I think the best solution in this case, where you want to do mainly
visibility cycling in an arbitrary mode is using outline-minor-mode and
bind org-cycle to some convenient command.
There is a FAQ which describes a setup for this,
"Can I get the visibility-cycling features in outline-mode and outline-
minor-mode?"

Ok, then I'll stay with this approach.
