1-mpgraph.mp gets this figure definition:
beginfig(1); verbatimtex \global \loadfontfileoncetrue \def \2##1##2{\vbox {\halign {\hfil ####\hfil \cr ##1\cr ##2\cr }}} etex; label(btex sun etex , origin); ; endfig;
environments are saved in macros, therefore you end up in an argument mess \starttext \startbuffer[mp] \def\2#1#2{\vbox{\halign{\hfil##\hfil\cr #1\cr #2\cr}}} \stopbuffer \def\useMPenvironmentbuffer[#1]% {\expanded{\startMPenvironment\noexpand\readfile{\TEXbufferfile{\jobname}}{}{}}\stopMPenvironment} \useMPenvironmentbuffer[mp] \startreusableMPgraphic{fig} label(btex sun etex, origin); \stopreusableMPgraphic \reuseMPgraphic{fig} \stoptext works ok ; maybe i should add that command to the core but anyhow you can wikify it
So the parameters in the definition are being doubled up by one of the transformations that inserts the verbatimtex..etex block. By the way, should the verbatimtex..etex block go outside the beginfig..endfig, as it would in a standalone MP file? If only for efficiency rather than MP reparsing it with each beginfig.
depends, if you process them runtime, it does not matter, if you process graphics between runs, they may be some cary over effects, although the btex/etex snippets are grouped Hans ----------------------------------------------------------------- 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 -----------------------------------------------------------------
