Hi list,
I'm having some trouble with MetaPost in general and MetaObj in
particular. I hope someone on this list can assist me here. I'm trying
to run the appended ConTeXt file with a quite simple object "Segment"
(from the manual [1], section 2.1). This script works fine as it is. I
wanted to add a simple TeX label ("\tt \overbar{E}") to the drawing
macro, but failed.
When including the line marked with "% 1" the TeX run fails. I don't
understand why.
The line with "% 2" is taken frome the metaobj manual (section 5.8) [1],
but including this doesn't work either.
It would be great if someone could tell me what's wrong with the mp-code
below and explain how to place a (TeX) label inside a metaobj object.
Thanks in advance,
Stefan.

For example \starttext \startMPcode path p; p := fullcircle scaled 4cm ; \stopMPcode \startMPcode draw p ; \stopMPcode \stoptext draws a circle. I am not convinced that this is useful. Resetting the state of mplib after each graphic might be better. Then, after the first run, you could just set the value of mptopdf.texts[..], reset the state of mplib, and then draw the graphic in the second run. This approach will have less surprises. For example, in simpleslides module, we provide a mechanism for highlighting a part of a picture using arrows. These arrows are thick (typically 5bp). In order to scale the arrows correctly, we set: autoarrows := true ; However, in the current implementation, this effect is global. It took a while to realize that this messed up all the figures with arrows that I was drawing in a presentation (where autoarrows := false) is better. Not resetting the mplib state also has advantages. For example, it allows an easy way to do something on the second path (trivial example, but there are cases when something like this makes the code much shorter): \startMPinclusions[+] newboolean flag ; flag := false ; \stopMPinclusions \starttext \startMPpage if flag : fill boundary withcolor 0.5[blue,white] ; else : path boundary ; fi ; path A, B; A := fullsquare scaled 3cm ; B := fullsquare scaled 3cm shifted (5cm,0) ; fill A withcolor white ; fill B withcolor white ; draw A ; draw btex A etex ; draw B ; draw btex B etex shifted (5cm,0) ; boundary := (boundingbox currentpicture) enlarged 3mm ; flag := true ; \stopMPpage \stoptext So, perhaps, we can have a `reset` key to \defineMPinstance, and let the user choose whether to reset after each graphic or not. If `reset=yes` is chosen, then such errors would not occur.

Your example works perfect. Many thanks for that as well. I didn't realize, that assignObj is causing the trouble, but now it's obvious. I'm just curious: the MP-code is only run twice by context if it contains labels, right? Otherwise I don't understand why the assignObj isn't always failing. > @Hans, can we have a `trialtypesetting` for MP code? > > Aditya Stefan ___________________________________________________________________________________ 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 : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 11+ messages in thread

"rotateObj(s, 90)" would rotate the object 180 degrees instead of 90; when defining the relation between several objects some equations may became redundant (my script is rather complex and I'm not sure why some of the equations cause trouble).

Depends on the internal implementation of MetaObj (I have not looked at that). You can try to iteratively add stuff and see what breaks, and then add if not flag around them. Sorry, but I do not know a more elegant way around this.

It seems it's savest to just put "if not flags" around the object constructors, object transformations and definition of inter-object relations. This does not produce graphical output, so it should be save to run it only once. > Sorry, but I do not know a more elegant way around this.
