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?
