Variables ¶

var ErrBadDataURI = errors.New("not a data URI")

ErrBadDataURI is returned by DataURI when the byte slice does not start with 'data:' or is too short.

Functions ¶

func Copy ¶

func Copy(src []byte) (dst []byte)

Copy returns a copy of the given byte slice.

func DataURI ¶

func DataURI(dataURI []byte) ([]byte, []byte, error)

DataURI parses the given data URI and returns the mediatype, data and ok.

func Dimension ¶

func Dimension(b []byte) (int, int)

Dimension parses a byte-slice and returns the length of the number and its unit.

func EqualFold ¶

func EqualFold(s, targetLower []byte) bool

EqualFold returns true when s matches case-insensitively the targetLower (which must be lowercase).

func IsAllWhitespace ¶

func IsAllWhitespace(b []byte) bool

IsAllWhitespace returns true when the entire byte slice consists of space, \n, \r, \t, \f.

func IsNewline ¶

func IsNewline(c byte) bool

IsNewline returns true for \n, \r.

func IsWhitespace ¶

func IsWhitespace(c byte) bool

IsWhitespace returns true for space, \n, \r, \t, \f.

func Mediatype ¶

func Mediatype(b []byte) ([]byte, map[string]string)

Mediatype parses a given mediatype and splits the mimetype from the parameters. It works similar to mime.ParseMediaType but is faster.

func Number ¶

func Number(b []byte) int

Number returns the number of bytes that parse as a number of the regex format (+|-)?([0-9]+(\.[0-9]+)?|\.[0-9]+)((e|E)(+|-)?[0-9]+)?.

func Position ¶

func Position(r io.Reader, offset int) (line, col int, context string, err error)

Position returns the line and column number for a certain position in a file. It is useful for recovering the position in a file that caused an error. It only treates \n, \r, and \r\n as newlines, which might be different from some languages also recognizing \f, \u2028, and \u2029 to be newlines.

func QuoteEntity ¶

func QuoteEntity(b []byte) (quote byte, n int)

QuoteEntity parses the given byte slice and returns the quote that got matched (' or ") and its entity length.

func ReplaceMultipleWhitespace ¶

func ReplaceMultipleWhitespace(b []byte) []byte

ReplaceMultipleWhitespace replaces character series of space, \n, \t, \f, \r into a single space or newline (when the serie contained a \n or \r).

func ToLower ¶

func ToLower(src []byte) []byte

ToLower converts all characters in the byte slice from A-Z to a-z.

func TrimWhitespace ¶

func TrimWhitespace(b []byte) []byte

TrimWhitespace removes any leading and trailing whitespace characters.

Types ¶

type Error ¶

type Error struct {
	Message string

	Offset int
	// contains filtered or unexported fields
}

Error is a parsing error returned by parser. It contains a message and an offset at which the error occurred.

func NewError ¶

func NewError(msg string, r io.Reader, offset int) *Error

NewError creates a new error

func NewErrorLexer ¶

func NewErrorLexer(msg string, l *buffer.Lexer) *Error

NewErrorLexer creates a new error from a *buffer.Lexer

func (*Error) Error ¶

func (e *Error) Error() string

Error returns the error string, containing the context and line + column number.

func (*Error) Position ¶

func (e *Error) Position() (int, int, string)

Positions re-parses the file to determine the line, column, and context of the error. Context is the entire line at which the error occurred.
