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.

Hi Jairo, Thank you very much for the suggestion and the thorough explanation. I extracted the metapost code to a new file because I felt it would be a bit lengthy and noisy to stay with the text content. But you're right, an extra compilation step is not any better. I should probably use \component figure.tex, in place of \externalfigure[figure.1] Sylvain
