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).
hm, that can be
mp.print(LUATEXFUNCTIONALITY or 0)
but ... i'm surprised you can use metafun in plain at all ... i never test that and to be honest am not too motivated to support mpiv code in generic either .. better use
Until TeX Live 2018, MetaFun worked in plain (at least the subset I'm using). It would be a shame if the support would end. I also think that there are quite a number of users. The number of posts on TeX Stack Exchange mentioning luamplib with metafun is not negligible. https://tex.stackexchange.com/search?q=mplibsetformat I (and probably a lot of other people) would really appreciate if you could apply Luigi's fix, so we can continue do enjoy MetaFun, even outside ConTeXt. Cheers, Henri

MWE is below, as always.
