Thank you Hans!

This is good news. Your work is very much appreciated. I am looking
forward to the next beta.

Dear all,

This is a long standing feature request reported multiple times by
myself and others with MWEs in
https://www.mail-archive.com/ntg-context@ntg.nl/msg79620.html and
https://www.mail-archive.com/ntg-context@ntg.nl/msg79727.html.

Another MWE in which the link is non-functional:

\setupexternalfigures[location={local,global,default}]
\setupinteraction[state=start, focus=standard]
\starttext
\about[figure].
\page
\placefigure[][figure]{Figure}{\externalfigure[cow.pdf]}
\stoptext

Please, Hans, I kindly ask you to reconsider. I am aware of your
opinion and reasoning about this issue. But I believe that for many of
us users, today's PDFs need to be both, interactive *and* printable.

If there is any way I can help or motivate you, then please tell me ;-)

Kind regards,

Christoph

The best way to motivate Hans to implement something you need, is by
implementing it yourself and sending him updated core files.
Works for me every time ;-)

Re: Reference links with focus=standard option

[Lawrence Bell]

Dear Christoph,

I take it from your reply that fixing this problem with interactivity
would likely cause some trouble with the printability? And therefore,
it's staying as it is to prioritize printability? That's understandable,
but a bit frustrating, since I still don't have any clue what the actual
problem is. Could you possibly explain in some more detail or point me
to a relevant thread?

Kind regards,

Lawrence

Reference links with focus=standard option

[Lawrence Bell]

[-- Attachment #1.1: Type: text/plain, Size: 1571 bytes --]

Hi mailing list,

I'm having some trouble with (interactive) references. I had a quick
search of the mailing list and couldn't find any talk about this kind of
issue, so I'm asking now. Hoping you could help me out.

Consider the following example document.

\setupinteraction
  [
    state=start,
    % focus=standard,
  ]

\starttext
\startchapter[title=Some Title, reference=pt:ref]

Lorem ipsum dolor sit amet, \periods

\startplaceformula[reference=eq:ref]
  \startformula
    c^2 = a^2 + b^2.
  \stopformula
\stopplaceformula

Lorem ipsum dolor sit amet, \periods

\startitemize[r]
  \startitem[it:ref]
    Lorem ipsum dolor sit amet, \periods
  \stopitem
\stopitemize

And now we can refer to formula~\in[eq:ref], chapter~\in[pt:ref], and
item~\in[it:ref].

\page

And now we can refer to formula~\in[eq:ref], chapter~\in[pt:ref], and
item~\in[it:ref].

\stopchapter
\stoptext

All is well with the default setting for focus. I don't like that with
most (?) PDF viewers the default setting changes the zoom level, so I
usually turn on \setupinteraction[focus=standard] instead. But this
seems to break (some of) the interactive links. The links to the the
chapter and item still work, but the links to the formula are broken.

As an experiment, I just tried this with a couple different viewers
(Firefox, Evince, Okular, Xpdf, Qpdfview) and (putting
\setupinteraction[focus=standard] back in) the link is indeed broken on
all of them, /except/ for Qpdfview which still seems to understand it.

What's going on here?

Thanks in advance, Lawrence

Hi Lawrence,

it seems that something is broken when ConTeXt generates the
destinations for these links.

qpdfview complains after having clicking the link:

    "Error: failed to look up (eq:ref)"
    "Error: failed to look up (eq:ref)"

> What's going on here?

I generated an uncompressed PDF document from your source:
http://pdf.ousia.tk/focus-standard.pdf.

The issue seems to be in the name tree node dictionary:

    35 0 obj
    <<
      /Limits [ (#1) (pt:ref) ]
      /Names [ (#1) 15 0 R (#2) 19 0 R (#3) 20 0 R (it:ref) 20 0 R
          (pt:ref) 15 0 R ]
    >>
    endobj

(eq:ref) seems to be missing there. But I have to investigate the issue
further to get a more accurate report.

I hope it helps,

Pablo

Lawrence,

all I got is that floats have problems with named destinations (the ones
you get with \setupinteraction[focus=standard]).

    \setupexternalfigures[location=default]
    \setupinteraction
      [state=start, focus=standard]

    \starttext

    \startplacechemical[reference=ch:ref]
      \startchemicalformula
         \chemical{(C_2H_5)_2Zn}{DEZ}
    \stopchemicalformula
    \stopplacechemical

    \placefigure[here][fl:ref]{Cow}{\externalfigure[cow]}

    formula \in[ch:ref]

    figure \in[fl:ref]
    \stoptext

Sorry, but I’m afraid that I don’t know exactly what misbehaves here. I
hope Hans can fix it.

Re: Reference links with focus=standard option

Pablo,

Thanks very much for your replies. It's reassuring to see (it seems)
that I've not overlooked some extra option that magically does the job
:) Worst case scenario I'll hack something together, or just settle for
the default focus functionality, which is not the end of the world. Just
feel like there should be a better/more elegant way.
