Hmm, I wonder if that diagnostic message (or logic around it) is frotzing the
package's internal state.

Weird.

"groff-man-pages.pdf" mostly has working `MT` hyperlinks in PDF.

But not in the "Authors" sections of groff_tmac(5) and groff(7).

Why?

Milestone reached: hyperlinked man(7) documents in PDF

[G. Branden Robinson]

Hi folks,

In a frenzy of activity over the past few days Deri and I have landed
everything necessary to bring full hyperlink support to man(7) documents
in PDF.

* The MT/ME macros hyperlink email addresses.
* The UR/UE macros hyperlink general URLs.
* The MR macro produces "man:foo(1)"-style hyperlinks.

This should have been easier than it was, but I'll save my gripes about
why it wasn't for a postmortem at another time.  :)

Further, Deri's "groff man pages book" is now the "official"
groff-man-pages.pdf document.  It adds a spare but attractive cover page
and, importantly, "internalizes" the man page hyperlinks when the
document itself provides the page in question.  "External" man pages
remain in "man:foo(1)" form.

I've successfully tested these features in Evince and xpdf.  Okular is
giving me problems as I reported to this list earlier today.

As always, you can check out the latest version of this and other groff
documents in a Dropbox folder.

https://www.dropbox.com/sh/17ftu3z31couf07/AAC_9kq0ZA-Ra2ZhmZFWlLuva?dl=0

I'd appreciate feedback and particularly any report of bugs that you may
spot.

What next?
==

mdoc(7) needs feature parity via its `Mt`, `Lk`, and `Xr`.  I'm already
working toward that, as recent commits will suggest.  Then we can say
that we have full PDF hyperlink support for _man pages_.

In man(7), it sure would be nice if we could turn paragraph tags into
hyperlinked text (this already works for `MR`, but not `MT` and `UR`).
I'm working on that, too.

Regards,
Branden

[bug #65232] Russian hyphenation is not working

[G. Branden Robinson]

Update of bug#65232 (group groff):

  Status:None => Need Info  

___

Follow-up Comment #1:

Hi Robin,

[comment #0 original submission:]
> I cannot get Russian hyphenation to work on a HEAD build of Groff. As far as
I understand, it should be enough to -mru.

It should.

> It should even enable hyphenation mode 8 by default.

That is _not_ my understanding.  The automated test assumes that loading the
"ru" package will set the hyphenation mode to 1 or 2.


$ grep -A2 mru tmac/tests/localization-works.sh 
output=$(printf "%s\n" "$input" | "$groff" -Tascii -P-cbou -mru 2>&1)
echo 'checking raw troff with -mru' >&2
echo "$output" | grep -Fqx '.hy=1' || wail

--
output=$(printf "%s\n" "$input" | "$groff" -Tascii -P-cbou -me -mru 2>&1)
echo 'checking -me with -mru' >&2
echo "$output" | grep -Fqx '.hy=2' || wail

--
output=$(printf "%s\n" "$input" | "$groff" -Tascii -P-cbou -ms -mru 2>&1)
echo 'checking -ms with -mru' >&2
echo "$output" | grep -Fqx '.hy=2' || wail

--
output=$(printf "%s\n" "$input" | "$groff" -Tascii -P-cbou -rcR=0 -man -mru
2>&1)
echo 'checking -man with -rcR=0 -mru' >&2
echo "$output" | grep -Fqx '.hy=2' || wail

--
output=$(printf "%s\n" "$input" | "$groff" -Tascii -P-cbou -rcR=1 -man -mru
2>&1)
echo 'checking -man with -rcR=1 -mru' >&2
echo "$output" | grep -Fqx '.hy=1' || wail


And indeed that's what "ru.tmac" sets up.


.\" Set up hyphenation.
.
.\" Russian hyphenation (\lefthyphenmin=2, \righthyphenmin=2)
.nr \*[locale]*hyphenation-mode-base 1
.nr \*[locale]*hyphenation-mode-trap 2


But we don't have in this automated test any Russian language text that we
check for correct hyphenation.  None was available.  If you can supply some,
that would be helpful.

> Still, I try to set HY and .hy manually without any success.
> 
> My source file UTF-8, converted to KOI8 using iconv, but I also included the
preconverted KOI8 file in case you don't have a working iconv. btw. that's a
very useful hack, as it preserves misc. codepoints as unicode character
escapes.
> 
> You have to install LiberationSerif, for instance using install-fonts.sh.
> 
> The command line to build the example used is:
> 

> iconv -f UTF-8 -t KOI8-R --unicode-subst='\[u%04X]' hyphen-utf8.ms | groff
-Tpdf -ms -mru >hyphen-koi8.pdf


Here's a thread from last March when we were first landing this change.

https://lists.gnu.org/archive/html/groff/2023-03/msg00100.html

You might compare your results with those we were getting at the time.

Regards,
Branden

I cannot get Russian hyphenation to work on a HEAD build of Groff. As far as I
understand, it should be enough to -mru. It should even enable hyphenation
mode 8 by default.

Still, I try to set HY and .hy manually without any success.

My source file UTF-8, converted to KOI8 using iconv, but I also included the
preconverted KOI8 file in case you don't have a working iconv. btw. that's a
very useful hack, as it preserves misc. codepoints as unicode character
escapes.

You have to install LiberationSerif, for instance using install-fonts.sh.

The command line to build the example used is:


iconv -f UTF-8 -t KOI8-R --unicode-subst='\[u%04X]' hyphen-utf8.ms | groff
-Tpdf -ms -mru >hyphen-koi8.pdf

PDF hyperlinks working in Evice and xpdf but not Okular

[G. Branden Robinson]

Thanks to Deri's recent pushes to the master branch in Git, we have PDF
hyperlinks in groff documents, including man(7) pages, and they're
beautiful.

However...I find that while the link text gets appropriately colored
when viewing gropdf(1)-generated PDFs in both Evince and Okular (which I
have handy), only in Evince do the links _work_.  I can click on them
and they do the right things.

xpdf also seems to work fine.

Does anyone know what's going on?  Is this an Okular bug, or some deeply
buried configuration knob in it that I need to twist?

Figured I'd ask here before I go hat-in-hand to KDE support channels,
with which I have no experience.

Regards,
Branden

I'm aware of it.  :)

The better way would be a resolution of Savannah #64134.[1]

You have have noticed that I've been giving fresh attention to how groff
man(7) handles the diversions it creates.

I've kept the "bad" page structure intact to make it really easy to tell
when I've solved the nested diversion problem.  My working copy has had
some "solutions", but they throw off line adjustment and look ugly.  I
think at this point it's simply a matter of whacking away at the problem
with careful attention to environmental issues.  I feel close.  If I get
unbearably stuck, I'll change the page to avoid the warnings.

Thank you for landing the changes that bring hyperlinks to life in
man(7) for PDF!  That was the immediate cause of me digging into the
aforementioned ticket.

Regards,
Branden

[groff] 03/05: Changes to satisfy bug #65231.

[Deri James]

deri pushed a commit to branch master
in repository groff.

commit 3e5f09d1b3a9df072cd2a67b648925049a655e82
Author: Deri James 
AuthorDate: Tue Jan 30 17:14:08 2024 +

Changes to satisfy bug #65231.

Alter build of groff-man-pages.pdf to use the new pdfmom,
so that all forward references (i.e. reference to groff_font(5)
in addftinfo(1) page) are handled properly. Also pass bookmark
names as text strings.

* doc/doc.am: Use pdfmom.
* tmac/an.tmac: Pass parameters to .pdfbookmark as a string.

To bring it more into line with the LinuxManBook.pdf add clickable links to
navigate between separate man entries in the volume, and add a front cover.
Also introduce the new pdfmom which can now work with all other macros, not
just mom, it's been waiting in the wings since the code freeze last year. It
also requires 3 lines change in an.tmac.

This causes a warning when viewing groff_out(5), because it has a nested .UR 
within a .TP. Replacing:-

.TP
.UR https://\:github.com/\:Alhadis/\:Roff\:.js/
.I Roff.js
.UE
is a viewer for intermediate output written in JavaScript.

With this:-

.P
.UR https://\:github.com/\:Alhadis/\:Roff\:.js/
.I Roff.js
.UE
.TP
\&
\v'-1.4v'is a viewer for intermediate output written in JavaScript.

Seems to work, in this instance, but perhaps there is a better way.

Cheers 

Deri
