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.
Thanks in advance for any idea and help.
Best regards: OK

It is amazing how fast one gets a solution to one's problem on this list… Just a note for Mathieu: I think that \enableregime[il1] is not needed in mkiv, since a unicode regime is the default there (however with mkii I use \enableregime[utf] but in the case we are discussing, one has to use lua, so mkiv is mandatory).
