I've been successfully using pdfmark to generate PDFs with bookmarks for some
time now, no problem. Now I'm trying to make my cross-references into actual
PDF links, and that's where I'm running into trouble. Part of the problem, I
suppose, is the part of the pdfmark documentation I need has not been written.
:-) The other part is that I'm trying to graft this feature into an existing
process, so I can't just rip it out and start over with pdfroff.
My current cross-reference generation consists of a macro XRT to define a
target based on the text and page of a heading immediately preceding:
.de XRT
.if \\n[TocGen] \{\
. tm XREF: xref:\\$1:txt \\*[xref:HDtxt]
. tm XREF: xref:\\$1:pg \\*[xref:HDpg]
.\}
.ie '\\*[.T]'html' .TAG \\$1
.el .pdfhref M -N \\$1
..
The strings "xref:HDtxt" and "xref:HDpg" are defined by the heading macro. The
argument to XRT was essentially a named destination tag to begin with.
Here's my big problem: the aux-file is full of entries like:
grohtml-info:page 170 353411 517000 355611 530398 540000 1 1
./somefile.ms
And I don't see anywhere in pdfmark.tmac where it outputs this particular
string. I'm guessing this is a hotspot definition, but the string
"grohtml-info" doesn't appear anywhere in pdfmark.tmac. I've looked at the
pdfroff script but it's not helping much.
What I need is a more generalized setup and some output I understand, then I
could perhaps pipe it back in and go from there.
