Functions ¶

func ParseFile ¶

func ParseFile(file *token.File, src io.Reader) (f *ast.File, err error)

func PrintError ¶

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.

Types ¶

type Error ¶

type Error struct {
	Pos token.Position
	Msg string
}

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.

func (Error) Error ¶

func (e Error) Error() string

Error implements the error interface.

type ErrorList ¶

type ErrorList []*Error

ErrorList is a list of *Errors. The zero value for an ErrorList is an empty ErrorList ready to use.

func (*ErrorList) Add ¶

func (p *ErrorList) Add(pos token.Position, msg string)

Add adds an Error with given position and error message to an ErrorList.

func (ErrorList) Err ¶

func (p ErrorList) Err() error

Err returns an error equivalent to this error list. If the list is empty, Err returns nil.

func (ErrorList) Error ¶

func (p ErrorList) Error() string

An ErrorList implements the error interface.

func (ErrorList) Len ¶

func (p ErrorList) Len() int

ErrorList implements the sort Interface.

func (ErrorList) Less ¶

func (p ErrorList) Less(i, j int) bool

func (*ErrorList) RemoveMultiples ¶

func (p *ErrorList) RemoveMultiples()

RemoveMultiples sorts an ErrorList and removes all but the first error per line.

func (*ErrorList) Reset ¶

func (p *ErrorList) Reset()

Reset resets an ErrorList to no errors.

func (ErrorList) Sort ¶

func (p ErrorList) Sort()

Sort sorts an ErrorList. *Error entries are sorted by position, other errors are sorted by error message, and before any *Error entry.

func (ErrorList) Swap ¶

func (p ErrorList) Swap(i, j int)

type Parser ¶

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