Hi,
I'm trying to define a new emphasis that would work like org-code (=) except
that it would export to \textsf instead of \texttt in LaTeX.
I tried several combinations using org-emphasis-alist and
org-export-latex-emphasis-alist, but I must admit that I'm lost amongst all
parameters controlling how the emphasis is processed:
- org-emphasis-alist defines a 'verbatim' optional parameter
- org-export-latex-emphasis-alist defines a protected (t/nil) parameter
- special format string like \\verb or \\protectedtexttt may also be used
Here are tests I've made (using the option ^:nil) with this reference string
=look_at:my~ti ny\reference^string=:
| verbatim | protected | format string | Resulting LaTeX code | Comment |
|----------+-----------+-------------------+---------------------------------------------------------------------------------------+-----------------------------|
| no | nil | \\textsf{%s} | look\_{}at:my\~{}ti ny\reference\^{}string | OK except for the backslash |
| no | t | \\textsf{%s} | look_at:my~ti ny\reference^string | NOT OK |
| yes | nil | \\textsf{%s} | look_at:my~ti ny\reference^string | NOT OK |
| yes | t | \\textsf{%s} | look_at:my~ti ny\reference^string | NOT OK |
| yes | nil | \\protectedtexttt | look\_at:my\textasciitilde\{}ti ny\textbackslash\{}reference\textasciicircum\{}string | NOT OK |
| yes | t | \\protectedtexttt | look\_at:my\textasciitilde{}ti ny\textbackslash{}reference\textasciicircum{}string | OK |
I would like to get the exact same output as == gives (no interpretation of
the chars I write) except that I'd like to use \textsf instead of \texttt but
I can't find the right combination for the parameters (verbatim, protected) to
achieve this goal.
Any help or comment is welcome.
Thanks a lot.
Francesco

If that's related to export, you can tweak the export of verbatim
(=text=) output.
For example, in the new exporter (if you use development Org, you can
(require 'org-export) and just call M-x org-export-dispatch), it just
means to change \texttt into \textsf through verbatim filters (list of
function applied to the output of each verbatim object).
It's a way to have the last words over export engine.
Here is the code:
#+begin_src emacs-lisp
(defun my-latex-verbatim-filter (text backend info)
"In `e-latex' backend, change \"texttt\" into \"textsf\"."
;; No change for other backends.
(if (not (eq backend 'e-latex)) text
(replace-regexp-in-string "\\`\\\\texttt" "\\\\textsf" text)))
(add-to-list 'org-export-filter-verbatim-functions 'my-latex-verbatim-filter)
#+end_src
If you call `org-export-dispatch' on a buffer containing:
=look_at:my~ti ny\reference^string=
you will get:
\textsf{look\_at:my\textasciitilde{}ti ny\textbackslash{}reference\textasciicircum{}string}

OK. Understood.

My goal is, in fact, to keep the default behavior of the '=' marker and redefine
the behavior of the '~' marker.
I'd like '~' to behave exactly the same way = does but using \textsf instead of
\texttt. Is it possible?
Thanks,
Francesco

Certainly. Even if we hard code syntax, the user always has the final
word on the produced text.
For now, the easiest way is to customize `org-e-latex-text-markup-alist'
and associate `protectedtexttt' to `code' value.
Then, since you want to change "texttt" into "textsf" in `code' objects
(~text~), add your filter to the right place (and remove the previous
one):
#+begin_src emacs-lisp
(add-to-list 'org-export-filter-code-functions 'my-latex-verbatim-filter)
#+end_src
In a few days, it will be also possible to write a function like the
following (which basically means "treat code as verbatim, but use textsf
instead of texttt"):
#+begin_src emacs-lisp
(defun my-latex-code-handler (code contents info)
"Handle `code' objects in LaTeX back-end."
(replace-regexp-in-string
"\\`\\\\texttt" "\\\\textsf"
(org-e-latex-verbatim code contents info)))
#+end_src
And tell the export engine to treat `code' objects with your function
instead of the default one.
