Types

type Generator

type Generator struct {
	// contains filtered or unexported fields
}

Generator contains program's AST and will store generated instruction sets

func NewGenerator

func NewGenerator(program *ast.Program) *Generator

NewGenerator initializes new Generator with complete AST tree.

func (*Generator) GenerateByteCode

func (g *Generator) GenerateByteCode(program *ast.Program) string

GenerateByteCode returns compiled bytecodes
