Re: [NTG-context] Clickable question/answer numbers

3 Nov 2016

      Dear Otared (and others),

while waiting for Hans reply on the \namedenumerationparameter and
\enumerationparameter, this is the best I could do. Now, only
"Question" is clickable and not the number, but I think I could live
with that if no other solution show up.

Best regards, Mikael

Dear Hans,
This seems to be exactly what I need, but I cannot get it to work.
With the example below nothing comes from those
commands (I just updated my standalone to the latest one). On the
other hand, with text instead of reference it works.
Best regards, Mikael
\defineenumeration[question][
text=Question,
]
\starttext
\startquestion[test]
This question has reference
\namedenumerationparameter{question}{reference} which could also
be achieved via \enumerationparameter{reference}. On the other hand,
\namedenumerationparameter{question}{text}
gives Question as assumed.
\stopquestion
\startquestion[reference=test2]
This question has reference
\namedenumerationparameter{question}{reference} which could also
be achieved via \enumerationparameter{reference}. On the other hand,
\namedenumerationparameter{question}{text}
gives Question as assumed.

Dear Otared,
thank you again. This is somehow a proof that it should work. In my
real document I use the title to name some exercises (after old
exams), and I don't see how that can be combined with your solution.
If someone else reads this: I think the question boils down to the
following:
\startquestion[Q:test]
How can I here automatically get access to to the string "Q:test"?
\stopquestion
it depends what automatically means
\enumerationparameter{reference}
or
\namedenumerationparameter{question}{reference}

Hi Mikael,
A partial solution to the feature we are discussing is contained in the
example below, but somone more aware of ConTeXtish coding might improve it.
It is not satisfactory in that one has to define twice \startquestion and
\StartQuestion, \beginanswer and \BeginAnswer, and more importantly one
cannot generate automatically the references (I tried \getnumber[question]
and such to append to Q:\getnumber[question] for instance, but something
does not work…).
Le me know if you find a satisfactory solution…

Indeed $(a+b)^2 = (a+b)(a+b) = a^2 + ab + ba +b^2 = a^2 + 2ab +b^2$ since

Dear Otared (and list),
thank you for your reply and support.
The links from the answers to the questions work as wanted with my
solution, it is the links from the questions to the answers that do
not.
I guess I need something like
headcommand={\in{Question}[A:###]},
where ### is the reference tag I set. But I don't know what to change
the ### into (or if that would work).
Best regards, Mikael

Hi Mikael,
I had a similar question some time ago, but I wanted to add a sort of
automatic referencing of questions and answers (and interaction going from
questions to answers and back).
If you accept the hurdle of adding manual references, in your case you
can add (for instance…)
\goto{:-)}[Q:test]
to the end of your answer to go back to the respective question. But
when you have several dozens of such references to add manually, it is not a
good idea.
However I could not find a way to code the items (that is the
questions) in such a way that each adds automatically a unique reference,
and so I am interested too in the solution of the problem you mention.
