latex wrap

[hello world]

[-- Attachment #1.1: Type: text/plain, Size: 439 bytes --]

Hi all,

having only used latex before: is there a way to prevent
emacs/org-mode---upon pressing M-q---to wrap a paragraph

bla bla
\begin{equation}
1+1=2
\end{equation}

into

bla bla \begin{equation} 1+1=2 \end{equation}

Can I make org-mode more aware of latex constructs? A different font-face
would also be really nice! I just like the M-q command. It's like the C-j of
Pine.
(I know, there's auto-fill-mode in emacs).

cheers,
josef

Why would you press M-q in such a location?

Turn on both org-export-with-LaTeX-fragments and
org-highlight-latex-fragments-and-specials

Because using org-mode as a note-taking program you may fiddle around on a
paragraph and when done press M-q to reformat it nicely on the screen. (At least
with auctex) it is nice that M-q is respecting also long \cite lists or %
comments which can help to increase readability of the tex-document.

that's great! thank you.

This behaviour is also bothering me. The example may not illustrate the problem
explicitly enough. Here is a more elaborate one:

I often find myself writing a paragraph that includes an equation like in this
example:

-----------------------------------------------------------------------
Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam
nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat,
sed diam voluptua. At vero eos et accusam et justo duo dolores et ea
rebum.
\[
a^2 + b^ = c^2
\]
Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum
dolor sit amet. Lorem ipsum dolor sit amet, consetetur sadipscing
elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore
magna aliquyam erat, sed diam voluptua. At vero eos et accusam et
justo duo dolores et ea rebum.
-----------------------------------------------------------------------

When writing such a paragraph you need to use M-q. In AUCTeX this is no problem.
You easily get the above paragraph using M-q. In org-mode, however, you get this:

-----------------------------------------------------------------------
Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam
nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat,
sed diam voluptua. At vero eos et accusam et justo duo dolores et ea
rebum.  \[ a^2 + b^ = c^2 \] Stet clita kasd gubergren, no sea
takimata sanctus est Lorem ipsum dolor sit amet. Lorem ipsum dolor sit
amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor
invidunt ut labore et dolore magna aliquyam erat, sed diam
voluptua. At vero eos et accusam et justo duo dolores et ea rebum.
-----------------------------------------------------------------------

This is quite confusing. A possible workaround to this problem is to insert
newlines around the equation like this:

-----------------------------------------------------------------------
Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam
nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat,
sed diam voluptua. At vero eos et accusam et justo duo dolores et ea
rebum.

\[
a^2 + b^ = c^2
\]

Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum
dolor sit amet. Lorem ipsum dolor sit amet, consetetur sadipscing
elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore
magna aliquyam erat, sed diam voluptua. At vero eos et accusam et
justo duo dolores et ea rebum.
-----------------------------------------------------------------------+

However, the equation is then put into a new paragraph which is not intended
here: The resulting PDF contains additional spacing around the equations. The
intention that this should be a single paragraph is not achieved.

It would be very nice to have the same behaviour in this setting as AUCTeX.

Cheers,
Patrick

Nice idea. This kind of works. Unfortunately, if the paragraph is indented the
hashes still have to be at column zero:

-------------------------------------------------------------------------
      Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed
      diam nonumy eirmod tempor invidunt ut labore et dolore magna
      aliquyam erat, sed diam voluptua. At vero eos et accusam et
      justo duo dolores et ea rebum.
#
      \[
      a^2 + b^ = c^2
      \]
#
      Stet clita kasd gubergren, no sea takimata sanctus est Lorem
      ipsum dolor sit amet. Lorem ipsum dolor sit amet, consetetur
      sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut
      labore et dolore magna aliquyam erat, sed diam voluptua. At vero
      eos et accusam et justo duo dolores et ea rebum.
-------------------------------------------------------------------------

This is still OK and for the upper part of the paragraph M-q works well.
However, hitting M-q in the lower part yields:

-------------------------------------------------------------------------
      Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed
      diam nonumy eirmod tempor invidunt ut labore et dolore magna
      aliquyam erat, sed diam voluptua. At vero eos et accusam et
      justo duo dolores et ea rebum.
#
      \[
      a^2 + b^ = c^2
      \]
# Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum
      dolor sit amet. Lorem ipsum dolor sit amet, consetetur
      sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut
      labore et dolore magna aliquyam erat, sed diam voluptua. At vero
      eos et accusam et justo duo dolores et ea rebum.
-------------------------------------------------------------------------

This is a problem itself. Text sneaking into a comment line upon hitting M-q is
not an expected behaviour -- at least not for me.

So the only acceptable workaround I know is to insert blank lines before using
M-q and to remove them afterwards.

Cheers,
Patrick

As I said,

the only fix is then rewriting the paragraph and wrapping code.
I have put it on my list, but this is not going to happen soon.

Hi Patrick,

unfortunately, I don't have a good solution for this, the filling
code in Emacs remains a mystery for me.  I am closing this task for now.

Hi Patrick,

I use filladapt.

I just tried your example and it works.  It also works if you indent
the comment lines to the same depth as the text.

See the thread, "Comments in org-mode" and this:

  http://article.gmane.org/gmane.emacs.orgmode/13312

Let us know if it doesn't work for you.

I guess Samuel is right, filladapt really is the solution here..
