[NTG-context] Can't use MetaFun with mplib anymore
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 ;
]]
print(ret.log)
}
\bye

Re: [NTG-context] Framed text split over multiple pages
Is there a simple way to split a large \startframedtext environment over multiple pages. It doesn't work out of the box and I didn't find any option make it work in the wiki nor in the documentation I read. Use backgrounds or textbackgrounds.

[NTG-context] Fwd: Question and Answer Iteration
This worked very well, thanks. I now want at the end of each chapter some
questions with the chapter number in the follow-up number, and then at the
end of the document a separate chapter with the answers with matching
numbers. In general for a single QA section this works, but now I start
distributing it over a number of chapters, the question and answer
numbering seems to be an issue. Would the define require a change?

Re: [NTG-context] ConTeXT install failing [solved]
My fault. A spurious older version of luatex too early in the search path.
Became disastrous only after the luatex version in the betas changed at some
point in time.
However in search of the problem I stumbled on a few statements invoking a Lua
error that can be avoided by safer coding, thus sparing non-programmers a
problem.
The error message is:
/tex/texmf-context/scripts/context/lua/mtx-context.lua:1819: attempt to index a
nil value (field 'filenames')
originates from:
elseif environment.filenames[1] or getargument("nofile") then
scripts.context.timed(scripts.context.autoctx)
I suggest to change this to (change highlighted)
elseif environment.filenames and environment.filenames[1] or
getargument("nofile") then
scripts.context.timed(scripts.context.autoctx)
The same applies to lines 1208, 1795, 1802
In line 1188 I recommend interchanging the operands for a more natural order;
here the check is already done.
local list = (name and { name }) or (environment.filenames and
environment.filenames[1]) or defaultformats
