Re: [Orgmode] Re: [org-beamer] \alert
Hi,
i just catched up reading the org list, and I think I can contribute to
this:
Carsten Dominik carsten.domi...@gmail.com writes:
Is there a LaTeX command that can figure out if it is running a beamer

If yes, a possible solution would be to redefine \alert in LaTeX when
not doing BEAMER.
The LaTeX Command \providecommand behaves exactly like \newcommand iff
the command does not already exist, so one (untested) solution would be
\providecommand{\alert}[1]{\emph{#1}}
I think this would be the cleanest way, but keep in mind that the
special beamer parameters are not supported by standard latex
command creation commands.

Hi all
I have been away for a week. Thanks for implementing this. Haven't tried
it yet.

Yes - this is in there now. Let's see if someone complains.

Thanks Tim. Very helpful indeed!
The following org-mode line does the job for me:
#+latex_header: \ifx\alert\undefined\let\alert\textbf\fi
If \alert is not defined, I have =alert= behave as =textbf=.
Alternatively, something like this also works:
#+latex_header: \ifx\alert\undefined\newcommand*{\alert}[1]{\textbf{#1}}\fi
in case one wants more control (e.g. could also change the colour to red).

Very true. I've never thought about this as my presentations are for
presentation only etc. However, it would definitely be nice to have a
more general solution.
Would there be a way to conditionally translate @...@ to alert (if
beamer) or
to emph (if not-beamer), so that we can still easily compile a
document to one
or the other LaTeX back-end, without having to customize
variables in Emacs,
prior to a compilation to the other back-end?
The alist structure doesn't allow for embedded lisp code, as far as I
can tell. It would obviously be easier if this structure could be
evaluated on the fly.
I must admit I do not have clear specifications on how to tell Org
about such
a config...
The only suggestion I can come up with would be to modify this
variable using, for instance, the org-export-later-after-initial-
vars-hook?

Essentially, you can add this functionality yourself:
