Hello,
what do I have to do so that the values (d1, m1, y1) from the Lua block 
are returned with Return and the commented out line
\date[d=d1,m=m1,y=y1][weekday,{,~},day,{.~},month,{~},year]
works in ConTeXt.
In other words: how do I do it right?

Thank you in advance
Greetings
Thomas

PS. Sorry, I'm a totally novice in Lua.


\starttext

\startluacode

function ddate(s)
i = 1
j = 4
y1 = string.sub(s,i,j)
i = 5
j = 6
m1 = string.sub(s,i,j)
i = 7
j = 8
d1 = string.sub(s,i,j)
context("Geht das:  %s.%s.%s", d1, m1, y1)         -- that works!
--return d1, m1, y1                                           -- that 
works not! Why?
end

\stopluacode

\def\DDate#1{\ctxlua{ddate("#1")}}

\DDate{20241005}
%\date[d=d1,m=m1,y=y1][weekday,{,~},day,{.~},month,{~},year]

\date[dd,mm,yyyy][weekday,{,~},day,{.~},month,{~},year]
\blank
\date[d=11,m=7,y=2024][weekday,{,~},day,{.~},month,{~},year]
