Hi, Sylvain.
LuaMetaTeX and LuaTeX, the engines used by ConTeXt nowadays, use an
embedded library, so external compilations/files are not necessary. Just
out of curiosity, wouldn't it be easier to use a ConTeXt environment? E.g.:
\starttext
\startMPcode %\startuseMPgraphic{<name>} if you want to reuse your graphic
with \useMPgraphic{<name>}
draw fullcircle scaled cm
%withcolor black % black is default
;
\stopMPcode %\stopuseMPgraphic
\stoptext
More info here: https://wiki.contextgarden.net/MetaFun_-_MetaPost_in_ConTeXt
To actually answer your question, if you actually want to load a Metapost
graphic externally generated, you should have something like:
%nice.mp
%"begin ... endfig", as well as "end" are important
beginfig (1);
draw fullcircle scaled cm
%withcolor black
;
endfig;
end
so when you compile it via
mpost nice.mp
(obviously supposing you have Metapost installed) you'll get a file called
nice.1 and
\starttext
\externalfigure[nice.1][width=4cm]
\stoptext
will work. However, as you can see, ConTeXt deals with such minutiae for
you and extends Metapost capabilities too, so the second alternative is not
the ConTeXt way to go.
I hope it helps.
Jairo :)
