syntax highlighting of inline LaTeX fragments

syntax highlighting of inline LaTeX fragments

[Ilya Shlyakhter]

dear org-moders,
is it possible to syntax-highlight inline LaTeX fragments,
such as $V$ or \cite{smith2012generating} ?
I know you can highlight LaTeX code blocks, but I'm looking specifically 
for highlighting of inline fragments.
thanks for help,
ilya

Also interested in if this is possible and what do you use to highlight
LaTeX code blocks.

I would also like this.

I may have to try out mmm-mode.

One solution is to use M-x latex-mode, then M-x orgstruct-mode, but headlines lose their syntax highlighting.

There is also a blob from [[http://stackoverflow.com/a/25048304/2533127][org-mode buffer latex syntax highlighting - Stack Overflow]], but I've so far only improved it to the following state:

#+BEGIN_SRC emacs-lisp
(font-lock-add-keywords
 'org-mode
 `(("\\$.+?\\$" . font-lock-keyword-face)
   ("\\$\\$.+\\$\\$" . font-lock-keyword-face)
   (,(concat "\\\\" "\\["       ; \[
             "\\("              ; \(
             "." "\\|" "\n"     ; .|\n
             "\\)" "*"          ; \)*
             "\\\\" "\\]")      ; \]
    . font-lock-keyword-face)))
#+END_SRC

So I now get some syntax highlighting on articles written in org like

#+BEGIN_SRC org
$$ W_{net} = \Delta KE. $$

On the other hand, the $i^{th}$ contribution to the work due to the $i^{th}$ force is /always/ 

\[
W_i = \int_{\textbf{a}}^{\textbf{b}} 
      \textbf{F}_i \cdot d\textbf{r}. 
\]
#+END_SRC

It's a little broken, for instance it doesn't react to changes in the buffer.

The variable `org-highlight-latex-and-related' should allow you to
highlight inline math.  For citations, one solution would be something
like [[cite:smith2012generatin][Smith (2012)]].

Hope it helps,
Rasmus

When in doubt, do it!

Thank you.

Takes care of all,
- $..$
- $$..$$ (w/ newlines)
- \(..\)
- \[..\] (w/ newlines)
- \begin{equation}..\end{equation} (w/ newlines)
