This gives the clearboxes error:
=================== box.tex =================== \startMPinclusions input boxes \stopMPinclusions
\starttext \startstaticMPfigure{fig} boxit.h(btex h etex); drawboxed(h); \stopstaticMPfigure \usestaticMPfigure[fig] \stoptext =====================================
The cause is that it produces this intermediate mp file:
========= box-fig.mp =============== input boxes boxit.h(btex h etex); drawboxed(h); ===================================
This fails because all three lines go into a beginfig..endfig and metapost fails. That may be a metapost bug in this case, but for robustness I think it should become:
input boxes beginfig(1) boxit.h(btex h etex); drawboxed(h); endfig; end
In order to do that transformation, box-fig.mp would need separate sections for the inclusions and for the main figure code.
Am I using inclusions incorrectly? i.e. Should I instead use MPextensions to get material placed at the top of the metapost file for use by all figures? Like this:
=============== box-e.tex ================ \startMPextensions input boxes \stopMPextensions
\starttext \startstaticMPfigure{fig} boxit.h(btex h etex); drawboxed(h); \stopstaticMPfigure \usestaticMPfigure[fig] \stoptext =======================================
But that produces
(texexec-mpgraph.mp
boxit.h ! Isolated expression. <to be read again> ( l.148 boxit.h( btex h etex ?
because the added extensions ('input boxes') are not included in texexec-mpgraph.mp.
the problem (if you look into the mp file) is that there is *no* beginfig; this is because we now use a more stupid (stripped down) variant of saving the graphic. \startstaticMPfigure{fig} beginfig(1); boxit.h(btex h etex); drawboxed(h); endfig; \stopstaticMPfigure i'll add the b/e to the main macro. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
