[BUG] Latex exporter should consider export settings [9.6.15 (release_9.6.15 @ /usr/share/emacs/29.3/lisp/org/)]

[Antero Mejr]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     https://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org mailing list.
------------------------------------------------------------------------

When exporting a latex document using `org-latex-export-to-latex`, a
\hypersetup section is added that contains the author name and title,
even though the variables `org-export-with-title` and
`org-export-with-author` are nil.

The \title{} section is also populated when `org-export-with-title` is
nil.

I think the latex exporter should work like the HTML exporter, and
respect the `org-export-with-*` settings to suppress the export of those
commands.

In this case, we should also eliminate the \maketitle right?

That seems to work, thanks. I attached a patch that handles
org-export-with-creator too.

It would be good if these fixes were also ported over to org-beamer,
since the same problem happens there.

[Pedro Andres Aranda Gutierrez]

Hi,

Thanks a lot. I would like a couple of days to look at the creator part specifically and adding this in to ox-Beamer. Or maybe even factoring out.

FTMB, let’s wait for Ihor’s reaction to this and discuss the pdfcreator part. 

The semantics behind is different. I happens to be the program that created the PDF.
Could you please expand on why you want to block that too?

Best, /PA

When publishing documents anonymously, as much metadata as possible
should be removed/removable. Also, it is misleading to have such a
setting if some exporters ignore it.

Re: [BUG] Latex exporter should consider export settings [9.6.15 (release_9.6.15 @ /usr/share/emacs/29.3/lisp/org/)]

[Pedro Andres Aranda Gutierrez]

Agree, but pdfcreator refers to a program, and thus it has nothing to do with exporting neither title nor author.

If you need this, you can always set the hypersetup in your eMacs configuration to fit your needs. BTW, this is what I needed to do once (in the very many presentations I have produced in the last 10 years).

I fear we go beyond the purpose of the org-export-with-* if we follow the path you suggest. 
@Ihor: WDYT?
