Re: [NTG-context] metaobj and luatex 0.42.0
Hi Matthijs, Thank you for your two follow ups to my original question. Both of the techniques you suggested also work for me, so I'm able to continue now. Cheers, Matt ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
Re: [NTG-context] metaobj and luatex 0.42.0
Hi Matthew,
However, I've found that cleaning up your objects when you're done pretty much
solves all my problems. For example, just add a clearObj line to your code
makes it work for me:
I've found that using save to declare the values as local also works. For
example:
\startMPinclusions
input metaobj;
\stopMPinclusions
\starttext
\startMPpage
save a;
newBox.a(\sometxt{hello world});
a.c = origin;
drawObj(a);
\stopMPpage
\stoptext
Perhaps this is even slightly more elegant.

Re: [NTG-context] metaobj and luatex 0.42.0
Hi Matthew,
I've been playing with metaobj and luatex 0.43 for a bit, and faced similar
problems. Lots of stuff about redundant equations and other stuff I didn't
understand.
However, I've found that cleaning up your objects when you're done pretty much
solves all my problems. For example, just add a clearObj line to your code
makes it work for me:
\startMPinclusions
input metaobj;
\stopMPinclusions
\starttext
\startMPpage
newBox.a(\sometxt{hello world});
a.c = origin;
drawObj(a);
clearObj a;
\stopMPpage
\stoptext
I'm not completely sure why this is clearObj a (and not clearObj(a), which
seems to be more logical considering drawObj also takes parentheses), but
that's probably something of the wonderful world of macro programming.
Hope this helps,
Matthijs

[NTG-context] metaobj and luatex 0.42.0
Hello everyone,
First, thanks for making this list such a great resource.
I've installed a fresh minimals on windows using first-setup.bat. This
seems to have installed luatex 0.40.6 which led to errors making the
formats (message indicated at least 0.42 was needed). I think the
presence of the older luatex version for windows was recently noted on
another thread.
So, I installed 0.42.0 and remade the formats.
This minimal example works with texexec example.tex but fails with context
example.tex.
\startMPinclusions
input metaobj;
\stopMPinclusions
\starttext
\startMPpage
newBox.a(\sometxt{hello world});
a.c = origin;
drawObj(a);
\stopMPpage
\stoptext
Is this expected to work (I realize the 0.42.0 is very new)
Am I doing something wrong?
Thanks very much for any assistance,
Matt

I am not surprised it fails. Most metapost code in mkiv is run at
least twice for some reason, and so equations tend to fail. You could
try with
\startMPpage
newBox.a(\sometxt{hello world});
a.c := origin;
drawObj(a);
\stopMPpage
but even then it depends on what newBox does internally.
in general one needs to keep in mind that we're in one run, so even in
the case of 'single runs' things can bleed from one to the other
graphic; one should set up graphics as independent as possible
