Suppose I have this code:
\startMPpage
vardef MyShape(expr w, h) =
save pth; path pth ;
save pic; picture pic;
pth = fullsquare xysized (w, h);
pic := image (
draw pth;
% all kind of stuff here
);
setbounds pic to pth;
pic
enddef ;
picture s ; s := MyShape(4cm, 2cm);
draw s;
drawdot center leftboundary s withpen pencircle scaled 2 withcolor green;
drawdot center rightboundary s withpen pencircle scaled 2 withcolor blue;
drawdot point .25 along topboundary s withpen pencircle scaled 2 withcolor yellow;
drawdot .25[llcorner s, lrcorner s] withpen pencircle scaled 2 withcolor magenta;
drawdot origin withpen pencircle scaled 2 withcolor red;
\stopMPpage
Can I reuse that varied across follow-up MPPages?

Does ‘once’ mean, valid in just one page or valid in all following pages?

Now, I am using my lua code to produce the METAPOST code that produces the pictures. And the picture itself is put in a file for METAPOST as follows: File test4-mplib-run-001.mp: % begin graphic: n=0 ; beginfig(1) ; defaultfont:="name:dejavuserif*default"; CurrentLayout:="article"; def OverlayLineColor=black enddef; def OverlayColor =black enddef; ;picture pic; x:=80.000; y:=200.000; w:=133.000; h:=53.000;pic := ApplicationComponentLogo( w, h, typeString) shifted (x, -y); draw pic;picture pic; x:=273.000; y:=253.000; w:=133.000; h:=53.000;pic := Function( w, h, typeString) shifted (x, -y); draw pic;picture pic; x:=380.000; y:=133.000; w:=133.000; h:=53.000;pic := Service( w, h, typeString) shifted (x, -y); draw pic;path p; p := (200.000,-227.000)--(333.000,-227.000)--(333.000,-273.000); draw p;path p; p := (393.000,-253.000)--(393.000,-180.000); draw p;;; endfig ; % end graphic This apparently is tried to get run through METAPOST separately and that clearly doesn’t work, because ApplicationComponentLogo isn’t defined. This is the result of the following setup: \starttext \startMPdefinitions (or inclusions, no difference) % ApplicationComponentLogo is defined here with a vardef \stopMPdefinitions \ctxlua{foo(“filename”)} % produces a series of % context.startMPpage { instance = "doublefun” } % several of: % context( METAPOST statements in a string) % context.stopMPpage() \stoptext How do I get my MPdefinitions available in those METAPOST runs?

Since you are using \startMPpage[instace=doublefun], you need to do the definitions for doublefun instance: so use \startMPdefinitions{doublefun} ... \stopMPdefinitions Aditya [-- Attachment #2: Type: text/plain, Size: 493 bytes --] ___________________________________________________________________________________ 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://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 8+ messages in thread
