Removing the date in a subtree export using the new exporter

Removing the date in a subtree export using the new exporter

[Alan Schmitt]

Hello,

I'm using the new exporter to create a pdf (through latex) of a subtree
of a huge file, and I want to remove some default information. I found
out a way to do it, but I'm not sure it's the right way. Here it is.

#+BEGIN_SRC org
:PROPERTIES:
:EXPORT_TITLE: Foo bar
:EXPORT_OPTIONS: toc:nil author:nil
:EXPORT_DATE: ~
:END:
#+END_SRC

The part about which I'm not sure is how to remove the date. I tried
putting nothing instead of the '~' but it does not work. Maybe there
could be an option for it?

Indeed, there could be a "date:nil" option. I'll add it later. Thanks
for suggesting it.

I wanted to fix this and saw that you already did. However it seems that
LaTeX still adds a date when a "\maketitle" happens with no date
specified. This small patch should fix this.

(Please let me know if it's not the good format to send the patch.)

It's better if you can provide a changelog entry and send it with "git
format-patch". Also, if you did not sign FSF papers, you will have to
add "TINYCHANGE" at the end of the change log.

Thank you.

I'll do this when I get back near a computer.

Also, about the FSF papers, is there a link for this procedure?

Thanks,

Alan

Great.

Certainly: http://orgmode.org/worg/org-contribute.html (in particular
the second section, but the whole page in interesting).

It basically boils down to sending a text form to assign@gnu.org.

Attached. With another question: should the patch be sent to the list,
or just to you (or any other process)?

I'll look into it.

Applied (with a slight twist). Thank you.

I've added you to the list of contributors without FSF assignment. Tell
me once you have signed them.

Please send any patch to the list.

Yes -- please do so.  Not only this is useful so that anyone
can review/test/comment the patch, but patches sent on the list
are stored on the patchwork:

  http://patchwork.newartisans.com/project/org-mode/list/

This helps not forgetting those we cannot process immediately.

Thanks for your contribution!
