# Prevent fill-paragraph from breaking LaTeX displayed equations in Org Mode

In Org Mode fill-paragraph brakes the following paragraph (containing LaTeX displayed equation)

* Some headline
Text text text
$e=mc^2$
text text text.


into

* Some headline
Text text text $e=mc^2$ text text text.


so the Org Mode form (with LaTeX preview) no longer reflects the LaTeX layout.

How can I prevent fill-paragraph from breaking LaTeX displayed equations?

UPDATE (edited on 11.04.2017)

By hacking org-element.el file I've modified org-element-paragraph-separate variable (in place of its definition). Now it includes also the "\\\\\$" regexp, so \[ is recognized as a place when new paragraph begins. The attempt to modify the org-element-paragraph-separate in my init file has failed. Unfortunately this is only a halfway solution: running fill-paragraph with cursor point before \[ does not break the equation, as expected, but when I run fill-paragraph having the cursor after \[ the paragraph changes to * Some headline Text text text \[ e=mc^2$ text text text.

• The examples in (org) LaTeX fragments lists a equation in exactly that inline format and also a longer $$...$$ syntax. The latter isn't modified when I'm calling fill-paragraph in the "Text text text" line. I have no LaTeX environment ready to test the inline $e=mc^2$ formatting – p_wiersig Dec 6 '16 at 23:36
• @p_wiersig $...$ can be compared to equation* environment or better to displaymath so (in LaTeX) there is a new line after $ and $ and the equation is centered. – premopie Dec 7 '16 at 11:12
