this is runtime tex into passed to the graphic ... imagine that we flush
this to the mp file ... it can contain info that is not known in that
session (like overlay info) which willbreak the mp run
the issue here is that a static graphic is processed in another,
independent run, that's the whole idea behind static graphics (quick
hack for independent graphics)
we can spend a lot of time to make it more advanced but within a year
from now we will have mp as a library in tex which willreduce runtime to
nearly zero (at least that 's what experiments show) so ....
what we can do is pass info from the mpenvironment"
\startMPenvironment[global]
\setupbodyfont[20pt]
\stopMPenvironment
\starttext
\long\def\startstaticMPgraphic#1#2\stopstaticMPgraphic
{\blabelgroup
\def\MPgraphicfile{#1}% no \jobname here
\let\MPwrite\MPstaticwrite
\immediate\openout\MPwrite=\MPgraphicfile.mp
\setMPrandomseedfalse
\enableincludeMPgraphics
\def\sometxt##1{\string\sometxt{##1}}%
\the\everyMPgraphic
\presetMPdefinitions
\theMPinclusions % brrr
\writeMPgraphic{\letterpercent mpenvironment: \the\everyMPTEXgraphic}%
\writeMPgraphic{beginfig(1);}%
\writeMPgraphic{#2}%
\writeMPgraphic{endfig; end.}%
\immediate\closeout\MPwrite
\immediate\closeout\MPwrite
\runMPgraphicstrue
\executeMPgraphicfile
\elabelgroup}
\startstaticMPfigure{fig}
label(\sometxt{in sometxt},origin);
\stopstaticMPfigure
outside sometxt
\usestaticMPfigure[fig]
\stoptext
for this we need to patch tex.rb:
def processmpstatic
if filename = getvariable('filename') then
filename += ".mp" unless filename =~ /\..+?$/
if FileTest.file?(filename) then
begin
data = IO.read(filename)
File.open("texexec.tex",'w') do |f|
f << "\\setupoutput[pdftex]\n"
f << "\\setupcolors[state=start]\n"
data.sub!(/^%mpenvironment\:\s*(.*?)$/mois) do
f << $1
"\n"
end
f << "\\starttext\n"
f << "\\startMPpage\n"
f << data.gsub(/end\.*\s*$/m, '') # a bit of a hack
f << "\\stopMPpage\n"
f << "\\stoptext\n"
end
report("converting static '#{filename}'")
runtex("texexec.tex")
pdffile = File.suffixed(filename,'pdf')
File.silentrename("texexec.pdf",pdffile)
report ("#{filename} converted to #{pdffile}")
rescue
report("error in converting #{filename} (#{$!}")
end
end
end
reportruntime
end
but that's about it
