internal link page numbers?

internal link page numbers?

Help?
 
I am writing markdown source in order to produce HTML output and PDF (via 
LaTeX) output.

I have two questions about internal links:

1. My internal links are being rendered, in PDF, as hyperlinks that are 
useful when viewing the PDF on a screen.   How can I have such links be 
rendered in a way that includes a page number, suitable for printed forms 
of the PDF?   (Of course, I hope the on-line PDF still has a clickable 
hyperlink.)

2. Is there a way to write a link to an internal section, such that the 
link text is *automatically* taken from the section name?   For example, if 
I have a section:

Appendix: The GNU General Public License 3.0 {#gnu-license}
============================================

then is there a way to write a link mentioning just "#gnu-license", and 
having the title of the appendix filled in automatically?

Thanks,
-t

You can use raw LaTeX \label{..}, \pageref{..} for this.
But there's no way to do it in native pandoc; pandoc doesn't
have a concept of pages, since only page-layout software can
know what page it's on.

You can just write

    [Appendix: The GNU General Public License 3.0]

and you'll get an automatic link with the title.

Thank you.  To get printed page numbers on references
I adopted this workaround:

In a custom LaTeX template I defined a macro PG,
after package hyperref is loaded:

\usepackage{hyperref}
\newcommand{\PG}[1]{\mbox{(p. \pageref{#1})}}

Thus I can write a link this way:

[copyright and licensing terms \PG{copyright}](#copyright)

which is not ideal but will do.

On the other issue, you suggest writing:

[Appendix: The GNU General Public License 3.0]

That's the opposite of what I am wishing for.  Supposing
a section header like this:

Appendix: Copyright and Licensing Information {#copyright .unnumbered}
=============================================

I wish I could write a link like this:

     [](#copyright)

And have the text "Appendix: Copyright ... Information" supplied
automagically.

That way, if I alter the section header, all such links
to the section stay in sync.

[John MacFarlane]

The shortcut you suggest isn't really in the spirit of
Markdown, which prioritizes source readability over
easy writeability.
