Org-mode with multiple major modes

Org-mode with multiple major modes

[Julien Barnier]

Hi to all,

And first of all, thanks for this stunning tool.

My problem is that I'd like to use org-mode in conjunction with
noweb-mode, which is used to distinguish code chunks and doc chunks in
my file, using two different major modes for each one (with org-mode
used for doc chunks).

It works great, except that when I move from a code chunk to a doc
chunk, org-mode seems to apply its startup options, and specially the
org-startup-folded one. So if I fold or unfold some sections in my
doc chunks, they are all folded or unfolded (depending on the
org-startup-folded value) when I move from a code chunk to a doc
chunk.

Do you have any idea on how to solve this minor point ?

Thanks in advance for any help,

Hi Julien,

Would this solve your problem?

  http://mmm-mode.sourceforge.net/

"MMM Mode is an emacs add-on package providing a minor mode that
allows Multiple Major Modes to coexist in one buffer."

In fact, I already have my two major modes coexisting in the same
buffer thanks to noweb-mode. What I am looking for is a way to
disable the org-startup-folded call when I move from a code chunk (in
another mode) to a doc chunk (in org-mode).

I don't think mmm-mode would solve the problem.

Thanks for your help,

(setq org-startup-folded nil)

Hi,

> (setq org-startup-folded nil)

Thanks for your answer, but it doesn't do what I wish. If I have some
part of my file folded and others not, with org-startup-folded set to
nil, when I move from a code chunk to a doc chunk, everything is
unfolded.

What I'd like is a way to disable this feature, or to enable it only
when I open the file, not when I switch from another mode to org-mode
in the same buffer.

But maybe it is a bit complicated for a minor issue.

Thanks again,

This is a different issue, and happens because is because outline-mode
pushes a `show-all' onto `change-major-mode-hook'.  Normally, this is
a good thing, of course, but not in your case.  So you need to
do something like

(add-hook 'org-mode-hook
    (lambda () (remove-hooK 'change-major-mode-hook 'show-all)))

However, written like this it will *always* be removed, so you need to
program it a bit more complex, with a test that the current buffer is
this is a noweb buffer or somwthing similar.

Hope this helps.
