Functions

func IntValue

func IntValue(lit []byte) (int64, error)

IntValue will attempt to parse a byte-slice as a signed base-10 64-bit integer.

func LitToRune

func LitToRune(lit []byte) rune

LitToRun will attempt to convert the literal value of a scanned token to a rune.

func RuneToString

func RuneToString(r rune) string

func UintValue

func UintValue(lit []byte) (uint64, error)

UintValue will attempt to parse a byte-slice as an unsigned base-10 64-bit integer.

Types

type Stack

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

func NewStack

func NewStack(capacity int) *Stack

NewStack will return a new, initialized stack.

func (*Stack) Len

func (this *Stack) Len() int

Len returns the number of items on the stack, or 0 if it is empty.

func (*Stack) Peek

func (this *Stack) Peek(index int) interface{}

Peek will return the item at `index` in the stack, where 0 is the bottom. Returns nil if the index exceeds the length of the stack.

func (*Stack) Pop

func (this *Stack) Pop() (item interface{})

Pop removes and returns the item at the top of the stack or nil.

func (*Stack) Push

func (this *Stack) Push(items ...interface{}) *Stack

Push places an item at the top of the stack or panics if item is nil.

func (*Stack) Top

func (this *Stack) Top() interface{}

Top returns the item at the top of the stack without altering the stack.
