Re: [NTG-context] Random selection of a word in a set with lua and mkiv
Dear Hans, dear Mathieu,
Thank you very much for your quick thoughts and solutions!
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).
Best regards: OK

Re: [NTG-context] Random selection of a word in a set with lua and mkiv
I see.So it can be fixed by simply adding the first line before the second
:\CHOOSERANDOM{""}\CHOOSERANDOM{"Maths", "Physics", "Algebra", "Analysis",
"Chemistry", "Geometry", "Wave equation", "Schrödinger equation"}Thanks, that
fixes one of my problems !

Indeed this is intended to be used in a TeX file processed with mkiv.
something
function document.r(str)

context(set[math.round(math.random(1,#set))])
end
\ctxlua{document.r("math physics")}

[NTG-context] Random selection of a word in a set with lua and mkiv
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
