NPL语言Meta编译器

• Extend NPL syntax with a LISP like AST structure.
• Compile *.npl source code into standard lua-compatible code (NOT byte code to support JIT) using AST (Compiler code needs to be written in NPL, please refer to metalua project)
• Add new NPL syntax to make NPL CAD language more expressive as a DSL (domain specific language)

Our goal is to support syntax like below in NPL cad.

translate(x,y,z){
     for i=1, 4 do
          rotate(i*45){  cube() }
     end
}

The above *.npl code will be compiled to following lua-compatible code via meta programming

push()
   translate(x,y,z)
      for i=1, 4 do
         push()
           rotate(i*45);
           cube()
         pop()
      end
pop()
