[bug] Asterisks in source and example blocks interpreted as headings

[bug] Asterisks in source and example blocks interpreted as headings

[Jason Dunsmore]

Hello,

I noticed that lines with leading asterisks inside of source and example
blocks are interpreted as headings:

--8<---------------cut here---------------start------------->8---
* Heading 1

#+begin_example
foo
* bar
blah
#+end_example

* Heading 2
--8<---------------cut here---------------end--------------->8---

If you put the point on "Heading 1" and hit TAB, you'll see the
following:

--8<---------------cut here---------------start------------->8---
* Heading 1...
* bar
blah
#+end_example

* Heading 2
--8<---------------cut here---------------end--------------->8---

I'm using GNU Emacs 23.2.1 and Org-mode version 7.7
(release_7.7.97.g9d5c5)

Regards,
Jason

Subject: [PATCH] org.el: Fix bug about headlines in blocks.

* org.el (org-cycle): Use `org-at-heading-p'.
(org-heading-forbidden-blocks): Variable alias to
`org-list-forbidden-blocks'.
(org-on-heading-p, org-at-heading-p): only perform the check
when we are in allowed blocks, otherwise just return nil.

Thanks to Jason Dunsmor for pointing at this.

Hm, I'm still seeing the same issue with both source and example blocks.

Yes -- my patch only took care of not allowing *manually* folding
headlines in selected environments.  But those headlines were still
folded when finding an org file with "#+STARTUP: fold" in it.

In the meantime, is it okay for you to TAB and have the commas
automatically added, as Sébastien suggested?

This requires

(setq org-src-tab-acts-natively t)

- Caraten

Sure, that works.  I've turned on `org-src-tab-acts-natively' as Carsten
suggested.  I also re-enabled `org-edit-src-content-indentation', which
was previously set to 0.

Hi,

AFAIK that is exactly the case, for which the "," rule is for.
Just put a "," in front of the offending line and everything will be fine.
On export the "," is removed.

best regards,
Daniel

Using org-edit-special bound to C-c ' to edit the contents of source or
example blocks will inserted the leading ","s automatically when they
are required.

Or TAB'ing inside the code block in the source Org buffer.

Best regards,
  Seb

PS- I (almost) never use the indirect buffer anymore, thanks to native
    highlighting.
