Re: [NTG-context] Can I share METAPOST vardefs over multiple pages?

This worked when I was just doing METAPOST. 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?

Suppose I have this code:

Can I reuse that varied across follow-up MPPages?

Sure, put the vardef inside \startMPinclusions: or \startMPdefinitions ... \stopMPdefinitions (don't remember what is the difference between inclusions and definitions, now). definitions: once inclusions : every time
