Thank you, Wolfgang, this works better.
Actually I need to use '%' in the condition and that fails:
---
...
\startrawsetups layer
% The value of 'n' is used here to set the appropriate background,
% = n-th page of a PDF, and also to draw a filled rectangle on
% the left or right side (depending on whether n is even or odd)
% The code bellow fails
\startluacode
print("N=", n)
if n % 2 == 1 then
else
end
\stopluacode
\stoprawsetups
...
---
with:
---
! LuaTeX error <main ctx instance>:1: 'then' expected near 'else'.
---
So like '%' was still treated as TeX comment char.
How to enable '%'?
Best regards,
Lukas
NB: Dirty trick: to define a Lua function like 'function isEven(n) return n % 2
== 0 end' and to use this function at the place of 'n % 2 == 1'; but I'd rather
avoid this.
