Hi all,

is it possible to write a lua function, named for instance

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)

Re: [NTG-context] Random selection of a word in a set with lua and mkiv
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(...)

Because context remembers the seed (is reported in the log). Delete the
tuc file and you will get another value. We could get oscillation
otherwise.

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 !

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

Hi all,
Assuming that we have a set of words or expressions, say

is it possible to write a lua function, named for instance
randomselectword
