[NTG-context] getcommalistsize
I wanted to do something with the length of a commalist but found
that it macro \getcommalistsize does not seem to respond.
Here is a small test:
\starttext
\def\showcommalist#1{commalist=(#1)\crlf
(size=\getcommalistsize[#1])\crlf
\processcommalist[#1]\showcommalistitem\crlf
(commalistsize=\commalistsize)\par}
\def\showcommalistitem#1{item = #1 }
\showcommalist{a,b,c,d,e}
\showcommalist{1,2,3}
direct call (size=\getcommalistsize[p,q])
\stoptext
result:
commalist=(a,b,c,d,e)
(size=)
item = a item = b item = c item = d item = e
(commalistsize=5)
commalist=(1,2,3)
(size=)
item = 1 item = 2 item = 3
(commalistsize=3)
direct call (size=)
As can be seen the macro \getcommalistsize does not give a value
back, \processcommalist works.
Am I doing something wrong here or understood it wrong?
yours sincerely,

Am I doing something wrong here or understood it wrong? \getcommalistsize puts its result (the length of the commalist) in \commalistsize, but does not expand to anything, so using direct calls does not work.

Thanks, I was right in suspecting I did not completely understand the effect of \getcommalistsize. It is clear now. yours sincerely, dr.
