[NTG-context] Re: Numbers obtained by commands <\datasetvariable> cannot be copied to counters

2024-05-29 Thread ai2472206007 
I must have made a mistake with something, I changed a counter and it somehow 
worked properly. Because I've designed too many counters, I still haven't 
figured out exactly what the problem is doing. But admittedly, the question I 
asked is non-existent. It's a problem with my design.

Thanks, probably interfered with his output in other parts of my command. I 
didn't locate the error correctly.

I'm defining a command to generate options for multiple choice questions,
but at the moment I'm stuck at this step.
I want to get a number and assign a value to the counter, but why can't I get 
it?


\starttext
\definedataset [myset]
\setdataset[myset] [foo=1,boo=4]
\newcount\tempa
\datasetvariable{myset}{1}{boo} % definitely get 4
%\tempa=\datasetvariable{myset}{1}{boo} % why i cannt pass 4 to tempa?
%\number\tempa
\stoptext
%

If anyone can fix it, thanka very much


You have to add a check to ensure there is a value stored in the 
aux-file before you pass the value to the counter. This is necessary 
because when you process the document for the first time Context only 
saves the value and can access it only in the next run after.


 begin example
\definedataset [myset]

\starttext

\setdataset [myset] [foo=1,boo=4]

\doifelsesomething{\datasetvariable{myset}{1}{boo}}
  {\scratchcounter\datasetvariable{myset}{1}{boo}}
  {\scratchcounter\zerocount}

boo = \number\scratchcounter

\stoptext
 end example

Works for me (minus comment signs of course):
