Re: Groff macro to make .UR and .UE links clickable in PDF?

> This is my output (diff to your output follows):

Thank you, Jan Stary. I am a bit confused because the intermediate
output you sent doesn't have any PDF hypertext information in it.

When I use 'gropdf' to parse it, the links aren't clickable. Same when
I paste it into https://rawgit.com/Alhadis/Roff.js/web-demo/index.html.

What output do you get from 'groff -V -mdoc -Tpdf'? For me, I see
'troff -mdoc -Tpdf | gropdf'. Also, what's your version of gropdf?

    $ gropdf --version
    GNU gropdf (groff) version 1.22.4

I had expected your intermediate output using groff -Z to include
"x X pdf: mark...", but it didn't. (See an example below). So, the
mystery deepens: is groff adding in hypertext in the postprocessor
stage? How?

--b9

P.S. Here's an example of groff intermediate output that gropdf and
Roff.js correctly turn into hyperlinks.
