Types

type ItemType

type ItemType int

A type for all the types of items in the language being lexed. These only parser SASS specific language elements and not CSS.

	NotFound          = -1
	ItemEOF  ItemType = iota
	ItemError
	IF
	ELSE
	EACH
	IMPORT

Special item types.

func Lookup

func Lookup(ident string) ItemType

Lookup ItemType by token string

func (ItemType) String

func (i ItemType) String() string

type Token

type Token int

Token is the set of lexical tokens of the Go programming language. Token is not currently used, but should be added to ItemType as CSS parsing is needed
