Latex export format control - emphasis and radio link

Latex export format control - emphasis and radio link

[Baptiste Fouques]

Hi,

I am using Org for a while, and I actually do like it a lot. I'd like
to extend my usage a bit, but I have some difficulties with export
format.
Basically, my point is about expanding/escaping control sequences in
latex output.

My sample org file is :

#+TITLE:     Org Test
#+AUTHOR:    Baptiste Fouques
#+EMAIL:     bat@m4tp.org
#+DESCRIPTION: org mode link test
#+OPTIONS:   ^:nil

* org-export-latex-emphasis-alist difficutlies

# <<<link_radio>>>

 =link_radio=

 =not_a_link=

* Radio Link format

<<<other_radio_link>>>


EOF-----------------

What I would expect as a Latex export would be :

\section{org-export-latex-emphasis-alist difficutlies}
\label{sec-1}

\label{link_radio}
 \texttt{\hyperref[link_radio]{link\_radio}}
 \texttt{not\_a\_link}

\section{Radio Link format}
\label{sec-2}
\label{other_radio_link}other\_radio\_link

EOF ----------------

But, I naturally get
...
 \texttt{[[link\_radio][link\_radio]]}                             {1}
...
\label{other_radio_link}other_radio_link                     {2}

which does not work at all as {1} is just a no-sense for LaTeX, and
{2} has not escaped the _ in plain text output (also the org header
has #+OPTIONS: ^:nil ).

I can manage to get {1} quite correct, manipulating
org-export-latex-emphasis-alist : ( ... ("=" "\\texttt{%s}" nil) ... )
...
 \texttt{\hyperref[link_radio]{link\_radio}}
...
but then, =not_a_link= became naturally broken ( _ are no more escaped ... )
And I found no such parameter that can be used to manipulate radio
link export format (to get <<<oher_radio_link>>> beeing exported as
\label{other_radio_link}other\_radio\_link .


If you could help me on this issue, I will be able to use Org mode
more widely in my everyday work (and propose it to my co-worker).

Thanks a lot,

Hi Baptiste,

first of all, why don't you just use not-a-lint instead of not_a_link?
Using underscore sort-of asks for problems in this context.

Also, why do you want the links to be in typewriter font?  This is  
unusual.  Maybe instead of modifying org-emph-alist, you'd want to add  
to it and create a new emphasis with is texttt but not verbatim?

Finally,

> <<<other_radio_link>>>

it is indeed a bug that this is not exported with escaped underscores.
I have fixed this issue.

Guess that I am not really looking for problems (I am not this type of
guy ;) ), but where I work, symbol names are defined with underscores
as word separators, and I need a tool that handle it ... And I prefer
facing the the problems when they come (well,  first trying to find
the correct way,  before asking for help).


> Also, why do you want the links to be in typewriter font?
still, it is about symbol names ... so the typewriter font, Then they
are defined once, then any reference should link to the definition ...

It do work, thanks for the advice. Also now I have to handle to prefix
for word that are radio-linked and those who are not ...

Thank you. Got it and confirm that it works.

Have a good Christmas
