Types

type Error

type Error struct {
	// Message contains the readable message of error
	Message string
	ErrType int
}

Error represents parser's parsing error

func InitError

func InitError(msg string, errType int) *Error

InitError is a helper function for easily initializing error object

func NewArgumentError(formerArgType, laterArgType int, argLiteral string, line int) *Error

NewArgumentError is a helper function the helps initializing argument errors

func NewTypeParsingError

func NewTypeParsingError(tokenLiteral, targetType string, line int) *Error

NewTypeParsingError is a helper function the helps initializing type parsing errors

func (e *Error) IsUnexpectedEmptyLine(len int) bool

IsUnexpectedEmptyLine checks if error is an 'end' with empty line

func (*Error) IsUnexpectedEnd

func (e *Error) IsUnexpectedEnd() bool

IsUnexpectedEnd checks if error is unexpected "end" keyword error

func (*Error) IsUnexpectedToken

func (e *Error) IsUnexpectedToken() bool

IsUnexpectedToken checks if error is unexpected token error

func (*Error) IsUnexpectedWhen

func (e *Error) IsUnexpectedWhen() bool
