accessing tex variable on lua side

accessing tex variable on lua side

Hello,

running in circles I have to give up on such an easy thing as passing a tex
variable to lua (knowing everything is stored in lua).

\setvariable{test}{something}{HHHH}
\starttext
\getvariable{test}{something}\par
% how to access the variable on lua end?
\startluacode
-- var =
\stopluacode
\stoptext

Thank you,
Jano

Never give up ...

\starttext

     \setvariable{test}{something}{HHHH}

     \getvariable{test}{something}\par

     \meaning\getvariable

     \startluacode
 
print(">>",tokens.getters.macro(tokens.getters.macro("??variables") .. 
"test:something"))
     \stopluacode

     \def\MyVariableSomething{JJJJ}

     \startluacode
         print(">>",tokens.getters.macro("MyVariableSomething"))
     \stopluacode

\stoptext

Thank you for reminding me of this one.

Not that trivial, but does the job.

Thanks,
