[NTG-context] MetaObj with labels in built-in objects (MetaObj Standard Library)
Hi list,
some time ago I posted on this list about problems with MetaObj in
ConTeXt when using labels. There's a wiki article about this now [1].
Just recently I was forced to notice that this solution does not work
when the label to be drawn is part of the object definition. So the
example from [1] works fine with the added boolean flag, but the
following example (which means basically all built-in MetaObj objects
with text) does not. It compiles well but there is no text.
--8start8--
\startMPinclusions[+]
input metaobj;
boolean firstrun; firstrun := true;
\stopMPinclusions
\startMPpage
if firstrun:
newBox.a(\sometxt{Text});
a.c = origin;
fi;
drawObj(a);
firstrun := false;
\stopMPpage
--8stop8--
I'm out of ideas how to fix this. I tried putting the text into a
separate pictrue variable and use this in newBox. In addition, I
thought it should be possible to modify metaobj.mp to check for a
boolean variable (e.g. firstrun) and let the macros there react to its
value accordingly , but I always got either no text or errors.
I can draw the picture I wanted to get in the first place with plain
MetaFun, but I thought MetaObj would be even more fun. Now I'm very
curious if someone on this list can come up with something. I think it
would be great if MetaObj could be fully used within ConTeXt.
Thanks in advance for taking the time to think about this and any hints!
Kind regards,
Stefan.

[NTG-context] metaobj
Hi everybody,
again a question by me, I found out that metaobj is included in
ConTeXt minimals and now try to figure out how to input this in a
ConTeXt document so I can use it in a
\startuseMPgraphic{name}
METAOBJ code
\stopuseMPgraphic
environment.
Thanks everybody for your help...

mcline.mat(1,1,2,2) nodesepA(3pt);
mat.c=origin;
drawObj(mat);
\stopuseMPgraphic
\useMPgraphic{commutativediagram}
\stoptext
what I don't understand is that this examples builds and runs fine under
mkii but not under mkiv, what did I do wrong, where is my error in this
code so it will not build?

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

[NTG-context] metaobj and colors

Any idea ?

Sorry I still do not see your white box. Perhaps something is corrupted

I had a quick look into mpobj source and I tried to remove default white

Me either.

color t; t:=(1,1,0);
%setObjectDefaultOption(Box)(fillcolor)(t);
newBox.test();

end.
Your color is not transparent, so it will work as expected: no white
box.

[NTG-context] metaobj and transparent colors with \MPcolor
Hi,
I try to achieve transparently filled objects using the metaobj package.
However, transparency is ignored completely in the output, I just get a
normal white. Here is my test file:
\setupcolors[state=start]
\setupbackgrounds[page][background=color,backgroundcolor=red]
\startMPenvironment[global]
\definecolor[Durchsichtig][r=1.0,g=1.0,b=1.0,t=0.0,a=normal]

\starttext
\reuseMPgraphic{test}
\stoptext
If I use the fillcolor as an argument to the object
newBox.test(btex Transparent? etex) filled(true)
fillcolor(\MPcolor{Durchsichtig});
I get error messages from the mpost run. So it seems that metaobj and
\MPcolor don't like each other.
Any ideas how to circumvent this problem?

But I have a question. It is really needed to surround \definecolor by
\startMPenvironment? Since \definecolor has to result to \pdfobj and
\pdfliteral (pdftex primitives) and propagation to mpost (which is EPS
not PDF generator) has no sence. Only reference to color is needed and
it is done via \MPcolor. Am I right?

input metaobj;
setObjectDefaultOption(Box)(fillcolor)(\MPcolor{Durchsichtig});
newBox.test(btex Transparent? etex) filled(true);
Obj(test).c=origin;
drawObj(test);
\stopreusableMPgraphic
\starttext
\reuseMPgraphic{test}
\stoptext
If I use the fillcolor as an argument to the object
newBox.test(btex Transparent? etex) filled(true)
fillcolor(\MPcolor{Durchsichtig});
I get error messages from the mpost run. So it seems that metaobj and
\MPcolor don't like each other.
Any ideas how to circumvent this problem?

Re: [NTG-context] metaobj and transparent colors with \MPcolor

However, transparency is ignored completely in the output, I just get a normal white. Here is my test file: Hi, I have never considered transparency in metaobj, and each part of an object is merely drawn, in some order depending on that object, and with some (opaque) color. It seems some serious surgery would be needed to seamlessly add transparency handling. It can certainly be done, be it only by working on an object structure, but I don't see a quick fix.
