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.
--8<--------------------start--------------------8<--
\startMPinclusions[+]
input metaobj;
boolean firstrun; firstrun := true;
\stopMPinclusions
\startMPpage
if firstrun:
newBox.a(\sometxt{Text});
a.c = origin;
fi;
drawObj(a);
firstrun := false;
\stopMPpage
-->8--------------------stop-------------------->8--
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.
