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. --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.
