Exported Type Names


	 type Error (struct)
		In an ErrorList, an error is represented by an *Error.
		The position Pos, if valid, points to the beginning of
		the offending token, and the error condition is described
		by Msg.

		
			Msg string
			Pos token.Position
		
			 (T) Error() string
		
			 T : error


	 type ErrorHandler (func)
		An ErrorHandler may be provided to Scanner.Init. If a syntax error is
		encountered and a handler was installed, the handler is called with a
		position and an error message. The position points to the beginning of
		the offending token.

		
			func (*Scanner).Init(file *token.File, src []byte, err ErrorHandler, mode Mode)


	 type ErrorList ([])
		ErrorList is a list of *Errors.
		The zero value for an ErrorList is an empty ErrorList ready to use.

		
			(*T) Add(pos token.Position, msg string)
			 (T) Err() error
			 (T) Error() string
			 (T) Len() int
			 (T) Less(i, j int) bool
			(*T) RemoveMultiples()
			(*T) Reset()
			 (T) Sort()
			 (T) Swap(i, j int)
		
			 T : error
			 T : sort.Interface


	 type Mode uint
		A mode value is a set of flags (or 0).
		They control scanner behavior.

		
			func (*Scanner).Init(file *token.File, src []byte, err ErrorHandler, mode Mode)
		
			const ScanComments


	 type Scanner (struct)
		A Scanner holds the scanner's internal state while processing
		a given text. It can be allocated as part of another data
		structure but must be initialized via Init before use.

		
			ErrorCount int
		
			(*T) Init(file *token.File, src []byte, err ErrorHandler, mode Mode)
			(*T) Scan() (pos token.Pos, tok token.Token, lit string)

Exported Values


	 func PrintError(w io.Writer, err error)
		PrintError is a utility function that prints a list of errors to w,
		one error per line, if the err parameter is an ErrorList. Otherwise
		it prints the err string.


	const ScanComments Mode = 1 // return comments as COMMENT tokens
