org-latex-fragments on sections

org-latex-fragments on sections

[Andreas Leha]

Hi, 

I am forwarding a question from stackexchange [1] here, as I am
interested in this myself and I think this a bug.

I just add that the behaviour is not as expected also when the prefixed
command (C-u C-c C-x C-l) is used.

begin_quote

In the following Orgmode file, I can't figure a way to preview only the
latex fragments of section 1.1 (= those contained in sections 1.1.1 and
1.1.2, not those of section 1.2 nor section 2)

#+begin_org
* section 1
** section 1.1
*** section 1.1.1
$\alpha=1$ 
*** section 1.1.2
$\alpha=2$
** section 1.2 
$\alpha=3$

* section 2 
** section 2.1
$\alpha=4$
** section 2.2
$\alpha=5$
#+end_org

unfortunately when my maker is at point

  ** section 1.1

the command org-preview-latex-fragment (C-c C-x C-l) has no effect.

Same question to preview only the latex fragments of (the whole) section
1, it seems that at point

  * section 1 

the command C-c C-x C-l processes ALL latex fragments (section 1 and
section 2) of the tree.

Andreas

I can't reproduce in neither Org 8.2 nor 8.3 using emacs -q.

When I put the cursor on ** section 1.1 and do C-u C-c C-x C-l I get the
desired fragments, i.e. section 1.1.1 and 1.1.2.

I just tried with emacs -Q (which I had not done previously) and can
still reproduce it.

My system info:

GNU Emacs 24.4.50.1 (x86_64-apple-darwin13.3.0, NS appkit-1265.21 Version 10.9.4 (Build 13E28)) of 2014-09-02 on mib106584i.local
Org-mode version 8.3beta (release_8.3beta-902-gd749e8)

Best,
Andreas

I'm on:

GNU Emacs 25.0.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.14.8) of 2015-02-27 on W530

Org-mode version 8.3beta (release_8.3beta-882-gf8731e @ /usr/share/emacs/site-lisp/org/)

And I just updated to latest version of master, and it still works.

This is what I see

Perhaps I misunderstood the issue?

That is strange.

I think you understood correctly.  That is what I'd like to see, as
well.  But I see this

Nothing strange after all.  I just forgot that I still had Nicolas (very
nice) patch about improved latex fragment handling applied.  On the
clean build I see the expected behaviour as well.  Thanks for your
effort in reproducing this.
