type Scanner struct {
	In     io.Reader
	Out    io.Writer
	Lineno int

	Filename      string
	Wrap          func(*Scanner) bool
	IsInteractive func(io.Reader) bool
	Context       YYcontext

	Interactive bool
	// contains filtered or unexported fields

type YYcontext ¶

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

type YYtype ¶

type YYtype struct {

YYtype is the structure returned by the lexer every time the scanner asks for the next token. If the lexer wants to return an error to the scanner it sets the Error field and leaves the Token empty.
