what are the influences after cancelling \hypersetup in org-mode?

问题

I make pdf in org-mode with my own preamble, but the PDF or tex file generated always appear the information resulting from:

(format "\\hypersetup{\n  pdfkeywords={%s},\n  pdfsubject={%s},\n  pdfcreator={%s}}\n"
(org-export-latex-fontify-headline keywords)
(org-export-latex-fontify-headline description)
(concat "Emacs Org-mode version " org-version))

those cods locate in ~/.emacs.d/org-7.8.11/lisp/org-latex.el

I cancelled it to prevent the useless information appearing at the first page of its PDF-file. However is it OK to delete such codes without any function lost?

what influences will be caused by this action?

Thank you for your help.

回答1:

Ok, I know how it is.

add the code into your preamble :

\usepackage{hyperref}

all are solved.

回答2:

In that same file you mention, (lisp/org-latex.el), it suggests

org-latex-hyperref-template...
Set it to the empty string to ignore the command completely.

So the following should work

(setq org-latex-hyperref-template "")

Alas, I've reading downloaded source code not the same as my current org version, so this didn't work. apropos may be an easy fix, so

M-x apropos RET hyperref RET

leads me to the variable org-latex-with-hyperref, so now I try

(setq org-latex-with-hyperref nil)

This worked for me.
