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

[Otared Kavian]

Hi Dalyoung,

Yes I see what your problem might had been. Recently ConTeXt creates a fine 
named FILENAME.tuc when one typesets FILENAME.tex. This *.tuc file creates 
difficulties when the typesetting is stopped for some reason or another, 
because then at times it is impossible to typeset again the same file even if 
the error has been fixed.

Maybe we have to ask Hans whether this behavior is intended or not: in any case 
one has to remove that *.tuc file manually in order to typeset again.

Best regards: OK

[Jeong Dal]

Dear Otared,

It is not the problem of your code. 
Strangely, the code you just sent to me is stopped by the same reason during 
the compilation
even though it does not contain the word “myanswer”.
After removing *.tmc file, the error disappear.  
I still don’t know why such an error occurred.

Anyway, I got a nice sample which is very useful.

Thank you.

Dear Dalyoung,

I guess you are typesetting the wrong file, or you have put the last code I 
sent into a file which contains something of the previous codes…
Indeed in the last file I sent (which I am sending again at the end of this 
reply) does not contain the command \myanswer… which appears in your error 
message.

Dear Otared,

Hi,
I run the given  code and got an error message as following.

tex error   > tex error on line 1 in file virtual://block.answer.2: ! 
Undefined control sequence

l.1 \myanswer

Would you please tell me how to avoid such an error?
It seems to me that you don’t have an error.

I am running minimal(beta) in OSX.

Thank you.

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

Hi Wolfgang, Hi Mikael,

Thanks Wolfgang! I didn’t know that \beginBLOCKNAME \endBLOCKNAME cannot be 
used in other macros… There is some mystery in this for me.

Now with 
\doifnotmode{*trialtypesetting}
everything works as expected. 

Since I don’t know whether, nor where on the wiki, this can be wikified, for 
the archives and for other possible users, I copy below the entire example 
which allows to have interactive Questions and Answers. One can also easily add 
a chapter for Hints, if necessary.

Hi Wolfgang,

Thanks for the solution you sent yesterday.
Your solutions solves the problem I was fighting with, but when I try 
to apply it to my real document there is an issue when some questions 
don’t have answers. This prevents the synchronization of Questions and 
Answers if one doesn't issue the commands

\beginanswer
\incrementcounter[answer]
\endanswer

right after a question without an answer. And when the above commands 
are issued, the last Question does not show the link to its 
corresponding Answer.


Below is your modified example where one can see the problem (please 
see the fifth Question in the source below).


Best regards: OK
 begin example-ws.tex

\setupinteraction[state=start]

\newcounter\QuestionCounter
\newcounter\AnswerCounter

\define[1]\QuestionTextCommand
  {\doglobal\increment\QuestionCounter
   \pagereference[question:\QuestionCounter]%
   \doifreferencefoundelse{answer:\QuestionCounter}
 {\goto{#1}[answer:\QuestionCounter]}
 {#1}}

\define[1]\AnswerTextCommand
  {\doglobal\increment\AnswerCounter
   \pagereference[answer:\AnswerCounter]%
   \doifreferencefoundelse{question:\AnswerCounter}
 {\goto{#1}[question:\AnswerCounter]}
 {#1}}

Add a check for triatypesetting mode to increment \QuestionCounter
only once for each question.

\define[1]\QuestionTextCommand
  {\doifnotmode{*trialtypesetting}
 {\doglobal\increment\QuestionCounter
  \pagereference[question:\QuestionCounter]}%
   \doifreferencefoundelse{answer:\QuestionCounter}
 {\goto{#1}[answer:\QuestionCounter]}

  {\doifnotmode{*trialtypesetting}
 {\doglobal\increment\AnswerCounter
  \pagereference[answer:\AnswerCounter]}%
   \doifreferencefoundelse{question:\AnswerCounter}
 {\goto{#1}[question:\AnswerCounter]}
 {#1}}

%% Why this command generates an erreor?
\define\noanswer{%
\beginanswer
\incrementcounter[answer]
\endanswer}

The block environment can’t be used within a definition but
you put the content in a bufer and call then the buffer content
with your \noanswer command.

\startbuffer[noanswer]
\beginanswer
\doglobal\increment\AnswerCounter
\incrementcounter[answer]
\endanswer

Hi Wolfgang, Hi Mikael,

Thank you both for your great inputs!

I tried to modify the code each of you sent yesterday in order to « 
couple » automatically each question with its answer, using the 
keyword « coupling=… », but somehow I am unable to create automatic 
references by extracting the number of each question or that of each 
answer, for example by using \rawcountervalue,
or \currentconstructionnumber. Strangely the latter gives the name of 
the construction and not a number: is it on purpose?
The \currentconstructionnumber command contains the name of the counter 
but getting the counter value won’t help because it comes too late.
The solution Wolfgang proposes today, using the new keyword 
referenceprefix, is almost perfect: however would it possible to 
create a version of
« currentconstructionreference » which creates a reference named for 
instance

answer:NumberOfCurentConstruction

The referenceprefix key is only usefull when you set the reference by hand.
The reason for which I need such a construction is that in a document 
with hundreds or more exercise —> hint —> solution, it would be handy 
to avoid creating each time a manual reference, and then one would 
navigate from a Question to its Hint and then  back to the Question or 
go to its Answer.
When you always all three elements (question, hint and answer) you can 
increment
a counter at the begin of each element and create a page reference which 
contains

the value of the counter.

Below is a modified version of my previous example for this method.

 begin example
\setupinteraction[state=start]

\define[1]\QuestionTextCommand
  {\doglobal\increment\QuestionCounter
   \pagereference[question:\QuestionCounter]%
   \doifreferencefoundelse{answer:\QuestionCounter}
 {\goto{#1}[answer:\QuestionCounter]}
 {#1}}

\define[1]\AnswerTextCommand
  {\doglobal\increment\AnswerCounter
   \pagereference[answer:\AnswerCounter]%
   \doifreferencefoundelse{question:\AnswerCounter}
 {\goto{#1}[question:\AnswerCounter]}
 {#1}}

\defineenumeration
  [question]
  [text=Question,
   headcommand=\QuestionTextCommand]

\defineenumeration
  [answer]
  [text=Answer,
   headcommand=\AnswerTextCommand]

\defineblock[answer]

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

[Otared Kavian]

Hi Wolfgang, Hi Mikael,

Thank you both for your great inputs!

I tried to modify the code each of you sent yesterday in order to « couple » 
automatically each question with its answer, using the keyword « coupling=… », 
but somehow I am unable to create automatic references by extracting the number 
of each question or that of each answer, for example by using \rawcountervalue,
or \currentconstructionnumber. Strangely the latter gives the name of the 
construction and not a number: is it on purpose?

The solution Wolfgang proposes today, using the new keyword referenceprefix, is 
almost perfect: however would it possible to create a version of
« currentconstructionreference » which creates a reference named for instance
answer:NumberOfCurentConstruction

The reason for which I need such a construction is that in a document with 
hundreds or more exercise —> hint —> solution, it would be handy to avoid 
creating each time a manual reference, and then one would navigate from a 
Question to its Hint and then  back to the Question or go to its Answer.

Best regards: OK

Dear Wolfgang,

thank you for the information. I will probably do that in next

Thank you very much Wolfgang!

Now I can get exactly what I need, see the example below (also tested
with my larger document, available at
http://www.maths.lth.se/matematiklth/personal/mickep/analysB2ht16/analys-context.pdf).

I'm very happy about this solution. Also, thanks to Hans for giving us
this very nice tool (I usually only write to the list when I have
problems, sorry)!

With the new beta you can set a default prefix for enumeration references,
i.e. you can write \startquestion[knuth] in your document without the need
to add a question or answer prefix.

\setupinteraction[state=start]

\define[1]\QuestionTextCommand
  {\doifreferencefoundelse{answer:\currentconstructionreference}
 {\goto{#1}[answer:\currentconstructionreference]}
 {#1}}

\define[1]\AnswerTextCommand
  {\doifreferencefoundelse{question:\currentconstructionreference}
 {\goto{#1}[question:\currentconstructionreference]}
 {#1}}

\defineenumeration
  [question]
  [text=Question,
   headcommand=\QuestionTextCommand,
   referenceprefix=question]

\defineenumeration
  [answer]
  [text=Answer,
   headcommand=\AnswerTextCommand,

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.
The reference value is set in a group and can only be accessed within 
this group

but you can use \currentconstructionreference to access it.

{\doifreferencefoundelse{question:\cldcontext{lpeg.match(lpeg.secondofsplit(":"),"\currentconstructionreference")}}

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

[Otared Kavian]

Hi Mikael,

Thank you for sharing the solution you found!

Your definitions suit me too, but in any case I’ll play with your code to see 
whether using the concept of « coupling » between each exercise and its 
solution (or hint, if one adds them) could allow the creation of an automatic 
interaction link between them, so that one can remove the necessity of adding 
manually a reference to each exercise and each solution.

Best regards: OK

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.
\stopquestion

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

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.

Best regards: OK
