how to export red colored TeX to latex

how to export red colored TeX to latex

[Uwe Brauer]

Hi

I want to obtain a latex file that contains

\textcolor{red}{$\delta \phi = \frac{2 m}{R}$}


However when I add 
\textcolor{red}{$\delta \phi = \frac{2 m}{R}$}

To an org file and export it as Latex, the construct ends up like this


\textcolor{red}\{\(\delta \phi = \frac{2 m}{R}\)\}

Which is wrong.

Any ideas how to obtain the correctly exported expression?

Thanks

Uwe Brauer

maybe @@latex:\textcolor{red}{$\delta \phi = \frac{2 m}{R}$}@@ will do.

Thanks! That worked!

Not exactly related, but if it helps, I have defined this custom link
for colored text segments:

(NB: I apply two colors for `:face', because normally I use two themes,
one clear for the day and another dark for the night hours: when my dark
theme is active, apply a background color. But you can simplify that part to
your liking):

(org-link-set-parameters "color"
			  ;; :display 'full
			   :face (lambda (path) (when path
						  (if (string= (face-attribute 'default :background) "#282c34")
						      `(:foreground ,path :background "#F5f5f5")
						    `(:foreground ,path))))
			   :export (lambda (path desc format)
				     (cond
				      ((eq format 'latex)
				       (concat
					"\\textcolor{"
					path
					"}{" desc "}"))
				      ((eq format 'html)
				       (format "<span
                                       style=\"color:%s;\">%s</span>"
                                       path desc)))))

The link would then look like this, adapting John's solution using a
LaTeX export snippet:

[[color:red][@@latex:$\delta \phi = \frac{2 m}{R}$@@]]

Thanks, right now, I don't need links but it is good to know that there is a way to use them.

It's just a way of using links to produce different strings, depending
on the export format (LaTeX, HTML...). I use them quite a bit for text
segments as \foreignlanguage{}{}, \textcolor{}{}, etc. Anyway, that
specific link does not have any associated link action.

Very nice Juan!  I would find this use of links quite useful.

Hi Eric,

Thank you. Yes, org-link-set-parameters is quite productive, and
addictive in occasions! :-): I also have link types defined for somewhat
extravagant things, such as linking videos and music from the dlna
server of my raspberry...

Anyway, for format chunks of text in export I think
org-link-set-parameters is a good alternative to macros.

Best regards,

Juan Manuel

I also have a few links defined (used to have one for citing but no
longer needed) but macros seem to be my first port-of-call and maybe
shouldn't be!
