Date format when exporting to LaTeX?

Date format when exporting to LaTeX?

[Richard Hansen]

Hi all,

I recently upgraded from 7.8.03 to current master (actually
release_8.0.3-299-g1d606c0) and now when I export to LaTeX, the following:

   #+DATE: %Y-%m-%d

no longer causes the date to be the current date in ISO 8601 format.  It
now simply prints "%Y-%m-%d".

I tried:

   #+DATE: {{{date(%Y-%m-%d)}}}

but got "Circular macro expansion: date".  I also tried:

   #+BIND: org-export-date-timestamp-format "%Y-%m-%d"

but that did nothing (no confirmation prompt, nothing).

Setting org-export-date-timestamp-format as a file-local variable didn't
work either.

Any hints?

Thanks,
Richard

This also doesn't work for, but I've never used it before.  But it
should be {{{time(.)}}} cf.

This works for me in Org-mode version 8.0.3
(release_8.0.3-309-gabacff).  Is the problem still persistent after
trying from emacs -q or after trying M-x org-reload?


#+BIND: org-export-date-timestamp-format "%Y-%m-%d"
#+DATE: <2013-07-01 Mon>

* test

#+begin_src emacs-lisp
(setq org-export-date-timestamp-format "%B %e, %Y")
(set (make-local-variable 'org-export-allow-bind-keywords) t)
#+end_src

I tried:

   #+DATE: {{{time(%Y-%m-%d)}}}

and that did work.  Thank you!

Unfortunately this does not work quite right with org-mode 7.8.03, so
I'll have to make sure everyone I collaborate with upgrades their
org-mode.  :(

This works for me too, but:

  * I must provide a date.  If I don't have that #+DATE line then the
    LaTeX exporter uses \today, and that ignores
    org-export-date-timestamp-format.  I don't want to have to specify
    a date; I want it to use today's date.  (The {{{time()}}} macro
    works well for this, but I was unaware of its existence until now.)

  * org-export-allow-bind-keywords must be true.  Adding it as a
    file-local variable is not an acceptable solution in my
    circumstance.

    I didn't have to set this variable when I was using 7.8.03 --
    org-mode simply asked me (once) if it was OK to bind the
    variables.  I miss that behavior.

Thanks again for letting me know about {{{time(.)}}}.

There are (hopefully few) incompatibilities between Org 7 and Org 8,
indeed. Be cautious about it.

Unfortunately, re-implementing that behaviour is not trivial. The
internals are just too different.

Yes, I remember we tried to re-implement this behavior.  Nicolas was
kind enough to provide patches per my request, as I think the previous
behavior is better.  If someone can help in this area, I think this
would be nice to fix this "regression".
