[NTG-context] Append to a commalist
Hello,
Is there a smart way to create a commalist?
I want to get the equivalent of
\setparameter[namespace][listname={item1,item2,item3}]
but be able to append one item at the time, like
\append{namepace}{listname}{item1}
\append{namepace}{listname}{item2}
\append{namepace}{listname}{item3}
I have tired this:
\def\append#1#2#3{
\fullexpandoneargafter\doifemptyelse{\getvariable{#1}{#2}}
{\edef\tmp{#3}}
{\edef\tmp{\getvariable{#1}{#2},#3}}
\setvariables[#1][#2={\tmp}]}
but it only works for one list. Apparently \tmp is not expanded so when
an item is appended to one list all other lists are affected. I have
tried \expanded but got the message stack full.
Any help would be greatly appreciated.

Great!
Thank you very much Hans. It would have taken me a lifetime to get there :)
