This following code works, except that the first random is always the same (Analysis) for some reason.
Anyone knows why ?
\enableregime[il1]\starttext\startluacode userdata = userdata or {} math.randomseed( os.time() ) function userdata.random(...) context(arg[math.random(1, #arg)]) end\stopluacode\def\CHOOSERANDOM#1{\ctxlua{userdata.random(#1)}}\dorecurse{10}{\CHOOSERANDOM{"Maths", "Physics", "Algebra", "Analysis", "Chemistry", "Geometry", "Wave equation", "Schrödinger equation"}\par}\stoptext
