Hi all,
I am exporting a document containing dates like this inactive one
[2011-10-17 Mo].
I do not want to change the displaying of dates in org mode (as that
breaks indentation and point movement). But I'd like this to be
exported as "Mo, 17.10.2011". How do I do that?
I found
,----
| org-e-latex-inactive-timestamp-format is a variable defined in `org-e-latex.el'.
| Its value is "\\textit{%s}"
`----
but I have no idea what to change that to or whether that is the correct
place to achieve the different data format at all.
Side note:
Ideally, in my opinion, the LaTeX-exporter would honor the
"#+LANGUAGE: XX"
setting and change the babel-settings accordingly and offer the option
to format the date/time-stamps differently for different languages.
Regards,
Andreas

Since you want to change contents, and not only markup, this isn't the
correct place.
You can either add a filter in `org-export-filter-timestamp-functions',
or implement your own function to handle timestamp objects. If you
choose the latter, you can install the function in
`org-e-latex-translate-alist' to overwrite current latex exporter
behaviour, or use `org-export-define-derived-backend' to implement your
own back-end.
Assuming you want to overwrite current behaviour, something along the
lines of the following (untested) should do the work:
#+begin_src emacs-lisp
(defun my-e-latex-timestamp (timestamp contents info)
(let ((value (org-translate-time (org-element-property :value timestamp))))
(setq value
(replace-regexp-in-string
org-ts-regexp1
(lambda (text)
(concat (save-match-data (org-trim (match-string 5 value))) ", "
(substring text 0 (1- (match-beginning 5)))
(substring text (match-end 5))))
value))
(case (org-element-property :type timestamp)
((active active-range) (format org-e-latex-active-timestamp-format value))
((inactive inactive-range)
(format org-e-latex-inactive-timestamp-format value))
(otherwise (format org-e-latex-diary-timestamp-format value)))))
(add-to-list 'org-e-latex-translate-alist 'my-e-latex-timestamp)
#+end_src
> Side note:

That seems reasonable. Is there any translation table between language
symbols and Babel options?

I won't bother doing this, but export engine internals probably permit
it.

Thanks a lot for that elaborate response. It got me where I wanted to be!

The following patch should add the language option according to LANGUAGE
keywords if babel package is explicitly loaded in preamble.
Is it what you had in mind? I'm a bit reluctant to load babel package if
not present.

I think this will be a great addition!

At first sight, I had no particular opinion about whether it's better to load
or not Babel by default.
After thinking about it, I think you're right NOT loading it by default. Babel
plays with cat codes for `:' among others, and can conflict with isodate IIRC.
Hence, better let the user decide to really include it or not.
Best regards,
Seb

Albeit a very limited one: guessed language in only added when babel
package is loaded _and_ it is different from the one set by the user.
If there is no objection, I'll push a slightly refactored version of
that patch.

I just made some quick test of your patch and it works great! So I
completely agree.

I do not mind. I can have '#+LATEX_HEADER: \usepackage[en]{babel}' in
all my .org files by default and have the exporter override the language
setting based on the '#+LANGUAGE:' tag.

Pleas do so. And a big thanks for that addition!

I've pushed the patch. Thanks for the language list.
Note that LANGUAGE doesn't override Babel package's options, but append
another language to them if not already specified.
Hence,
#+LATEX_HEADER: \usepackage[english]{babel}
#+LANGUAGE: fr
will produce
\usepackage[frenchb,english]{babel}
Should it replace previous language instead?

That's wrong a the main language is the latest loaded (here: english).
> Should it replace previous language instead?
I would think so, or at least suffixed, instead of being prefixed.
Of course, this is related to the question: do we allow or want multiple
languages in one document? If the answer is yes in LaTeX, how do we do in Org,
and for the HTML export (for which the value of #+LANGUAGE is also used).
Honestly, I don't care that much about one or the other, as I don't have to
type documents with multiple languages inside them. Or, if I would, I would
accept to insert LaTeX code inside my Org file to fix whatever needs to!
Best regards,
Seb

Good point.

From now, it will be suffixed.

This is unrelated to HTML. Each back-end handles #+LANGUAGE: keyword as
needed, if at all. There's no global specification about that keyword.
Moreover, it's simpler to implement that way. So, if there is no
drawback with having two languages, let's keep it simple.
