# bf0x
A static brainfuck compiler in c++0x.

Code is fed to the compiler using a big ugly variadic template.

auto multiply = bf0x::interpreter<bf0x::bstack<bf0x::interpreter>,
         ',','>',',','>','+','+','+','+','+','+','+','+','[','<','-','-',
         '-','-','-','-','<','-','-','-','-','-','-','>','>','-',']','<',
         '<','[','>','[','>','+','>','+','<','<','-',']','>','>','[',
         '<','<','+','>','>','-',']','<','<','<','-',']','>','>','>',
         '+','+','+','+','+','+','[','<','+','+','+','+',
         '+','+','+','+','>','-',']',',','<','.','>','.'>();
    
    bf0x::state st;
    multiply.exec(st);

A bunch of variadic templates consume the string char by char, using pattern
matching (partial specialization on the first char) and build a big recursive
function `exec(state& st)` which is then inlined and optimized by the c++0x
compiler.

Thanks to the c++0x compiler, mix of `+`, `-`, `<` and `>` are simplified.
For example, the code "`>++++++++[<------<------>>-]`" is assembled into
something equivalent to :

data[0] = 8;
    while (data[0] != 0) {
        data[1] -= 6;
        data[2] -= 6;
        data[0] --;
    }
