Dear list, I have a pretty large text with a lot of questions and answers, and want the user(students) to be able to click in the pdf to go from a certain exercise to its answer, and back. I have a solution (see below) to go from answers to questions, but not the other way around. I simply have no idea on how to make the red text (in the head) in the example question clickable with the answer on the next page as target. As you can see, the answer has a tag A:Q:test (I want to set these automatically in that manner), and clicking the green text I get to the correct place. I just don't see how to make the "Question 1.1" clickable with that target. I hope I make myself clear. If it matters, in the solution one could assume that the optional tag of the \startquestion \stopquestion is given for all questions.

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. Best regards: OK

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).

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…).

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 \stoptext On Thu, Nov 3, 2016 at 10:34 AM, Hans Hagen wrote:

Hi 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.

Best regards: OK

Dear list,

I have a pretty large text with a lot of questions and answers, and want the user(students) to be able to click in the pdf to go from a certain exercise to its answer, and back. I have a solution (see below) to go from answers to questions, but not the other way around. I simply have no idea on how to make the red text (in the head) in the example question clickable with the answer on the next page as target. As you can see, the answer has a tag A:Q:test (I want to set these automatically in that manner), and clicking the green text I get to the correct place. I just don't see how to make the "Question 1.1" clickable with that target.

I hope I make myself clear. If it matters, in the solution one could assume that the optional tag of the \startquestion \stopquestion is given for all questions.

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

Mikael P. Sundqvist mailto:mickep@gmail.com 3. November 2016 um 16:14 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.

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

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] \startbuffer % \startquestion \input knuth \stopquestion % \beginanswer \startanswer \input knuth \stopanswer \endanswer % \stopbuffer \starttext \dorecurse{10}{\getbuffer} \page \useblocks[answer] \stoptext %%%% end example Wolfgang

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.

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.
