[NTG-context] Lua MP

2010-09-30 Thread Procházka Lukáš Ing . - Pontex s . r . o .

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

no


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.
