func (T) IsNumeric

func (t T) IsNumeric() bool

func (T) IsNumericOrIdent

func (t T) IsNumericOrIdent() bool

func (T) String

func (t T) String() string

type Token

type Token struct {
	Range      logger.Range // 8 bytes
	UnitOffset uint16       // 2 bytes
	Kind       T            // 1 byte
	IsID       bool         // 1 byte
}

This token struct is designed to be memory-efficient. It just references a range in the input file instead of directly containing the substring of text since a range takes up less memory than a string.

func (Token) DecodedText

func (token Token) DecodedText(contents string) string

type TokenizeResult

type TokenizeResult struct {
	Tokens               []Token
	ApproximateLineCount int32
	SourceMapComment     logger.Span
}

func Tokenize

func Tokenize(log logger.Log, source logger.Source) TokenizeResult
