Hi,
I try to create a Metapost path in lua and it works so far for the attached example. But a call of that function from another lua function sadly fails (no path visible after call). The code seems to be executed later (the output from 'show pid;' appears somewhere later in the log).
How can I ensure that the code is executed at runtime?
I don't understand the issue but isn't there a
metafun("draw p;")
missing then?
Setting the bounding box has the same effect, as drawing something. Both methods avoid that the emtpy graphic is ignored by ConTeXt.
Anyhow, the MP path is not available in metapost.variables after the function call. If there is no other way I have to call the function from the TeX side (like in the attached example). Will look into that tomorrow.
