Hi all,
Assuming that we have a set of words or expressions, say
{Maths, Physics, Algebra, Analysis, Chemistry, Geometry, Wave equation,
Schrödinger equation}
is it possible to write a lua function, named for instance
randomselectword
which returns one of the words or expressions selected at random in the above
set?
Indeed this is intended to be used in a TeX file processed with mkiv.
something
function document.r(str)
local set = utilities.parsers.settings_to_array(str)
context(set[math.round(math.random(1,#set))])
end
\ctxlua{document.r("math physics")}
(untested)
