Hi! Is it possible to get the value of a MetaPost variable from TeX? It can, e.g., add "show u;" to MetaPost input, then parse output. I want to pretty- print the values of some MetaPost variables. Another question: is it possible to query the expansion of a macro from inside \directlua, if I have a variable that stores the macro name?
