Hello,
is it possible that Lua gets value of a MetaPost variable?
Let's have MetaPost code:
z11=(0,0)
z12=(1,1)
z21=(0,1)
z22=(1,0)
aa[z11,z12]=bb[21,z22]
So now aa = bb = 0.5.
And I'd need to access MetaPost values 'aa' and 'bb' from Lua (e.g. in Lua: "local a = mpost.aa, b = mpost.bb").
Is it possible somehow?
Regards,
Lukas

I don't know how MPlib handles metapost terminal output, but if you can
capture the terminal output in lua, then you can use
show aa, bb;
in metapost and parse the output in lua.
