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.

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'?

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 > promotion, stars are hard-coded. 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. Bye, Tassilo -- Chuck Norris sheds his skin twice a year. ^ permalink raw reply [flat|nested] 7+ messages in thread

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?" - Carsten On Mar 17, 2009, at 9:21 AM, Tassilo Horn wrote: > Carsten Dominik <dominik@science.uva.nl> writes: > > Hi Carsten, > >>> I wonder if I cannot make `orgstruct-mode' work the same way.
