Dear list,
Something has changed in MetaFun and it can no longer be used in
plain LuaTeX,
with neither of
luatex test.tex
mtxrun --script plain test.tex
This is the error:
>> LUATEXFUNCTIONALITY
>> "mp.print(LUATEXFUNCTIONALITY)"
! Equation cannot be performed (numeric=string).
MWE is below, as always.
Cheers, Henri

\directlua{
local mpkpse = kpse.new(arg[0], "mpost")
local function finder(name, mode, ftype)
if mode == "w" then
return name
else
return mpkpse:find_file(name,ftype)
end
end
local mpx = mplib.new {
find_file = finder
}
local ret = mpx:execute[[
boolean mplib ; mplib := true ;
input metafun.mp <http://metafun.mp> ;
]]
print(ret.log)
}
\bye
in mp-mlib.mpiv it seems that we should have
string LUATEXFUNCTIONALITY ; LUATEXFUNCTIONALITY :=
runscript("mp.print(LUATEXFUNCTIONALITY)") ;
instead of
numeric LUATEXFUNCTIONALITY ; LUATEXFUNCTIONALITY :=
runscript("mp.print(LUATEXFUNCTIONALITY)") ;
Now I have
tex/texmf-context/metapost/context/base/mpiv$ grep -r LUATEXFUNCTIONALITY
mp-mlib.mpiv:%numeric LUATEXFUNCTIONALITY ; LUATEXFUNCTIONALITY :=
runscript("mp.print(LUATEXFUNCTIONALITY)") ;
mp-mlib.mpiv:string LUATEXFUNCTIONALITY ; LUATEXFUNCTIONALITY :=
runscript("mp.print(LUATEXFUNCTIONALITY)") ;
and your example looks ok.
as currently the variable is isn't used we can also comment it
