Re: [NTG-context] luaTeX and on-the-fly MetaPost compilation

glue to tex:

of course this need to be embeded in some general mp support
(i'll add it to my todolist; actually a bit more is involved since one
probably wants to include the data between the figures too since it may
be called upon)
Thank you for the outline. For the exact mechanism of how to process an
.mp file I think there are three possible cases:
1. Strictly process what's between figure(n)..endfig only.
For this example
pair pnt;
pnt:=origin;
beginfig(1);
pnt:=(100,100);
drawdot pnt;
endfig;
beginfig(2);
drawdot pnt;
endfig;
end
compilation of figure 2 should fail, since variable pnt is undeclared.
2. Process everything up-to the specified figure, omitting stuff inside
non-matching figure numbers. In the example above, the output of figure
2 should be a dot at point (0,0). This case is convenient if multiple
figures share common variables or macros that are defined outside the
scope of beginfig..endfig. This should be the default case for .mp file
interpretation.
3. Process everything up-to the specified figure, including all
non-matching figures, but discard their output. That is, in the
example, the output of figure 2 should be a dot at point (100,100),
since pnt was modified in figure 1.
Note, this is not a pressing feature for me. The advantage is that
MetaPost and TeX code can be held in separate files (which has several
advantages) and users can easily compile the code in a single TeX run,
without knowing about Makefiles. Well, there is the \write18 feature.
But that is as difficult to use as a Makefile or even more difficult for
the inexperienced user.

[NTG-context] luaTeX and on-the-fly MetaPost compilation
Hi,
I didn't have the opportunity to touch luaTeX yet, but let me ask one
question in advance: Since luaTeX has a built-in MetaPost interpreter,
is it possible to refer to a certain figure in a MetaPost source file
for inclusion, instead of a compiled figure?
As an example, I would like to say in a TeX document (syntax may differ)
\includeMetaPost{foo.2}
and this should not refer to the pre-compiled file
foo.2
but to section
figure(2);
...
endfig;
in file
foo.mp
and compile it on-the-fly. Would that be possible?
Rationale: I do not want to mix TeX and MetaPost code. Probably, I'll
stick with compiling .mp files prior to the TeX run anyway, but I'm
curious about this option.
Best regards,
Stephan Hennig

[NTG-context] MetaPost v1.003: graph package broken
A note from the MetaPost developers: We have noticed an incompatibility between the latest MetaPost v1.003 and the graph package. Severity is considered high, since it prevents compilation of even the most simple figures. The problem is identified and a fix is under way. A workaround is not possible. Users of the graph package should not update to MetaPost v1.003. MetaPost versions 1.002 and prior are not affected.
