Functions

func Assemble

func Assemble(code string) []byte

Assemble generates bytecode from GOVM ASM.

func CleanCode

func CleanCode(code string) []string

CleanCode remove comments, trim lines etc.

func ParseNumber

func ParseNumber(str string) uint16

ParseNumber converts a hex-, octal- or decimal number into a word.

func ParseString

func ParseString(str string) []uint16

ParseString converts a string into a utf-16 encoded slice of words.

Types

type PointerReference

type PointerReference struct {
	Name      string
	Line, Arg int
}

PointerReference represents a assembler reference to a point in memory.

func ParseCommand

func ParseCommand(args []string, line int) ([]uint16, []PointerReference)

ParseCommand parses a specific command and returns a word representation and a slice of pointers.
