Functions ¶

func ParseNum ¶

func ParseNum(s string, n *NumInfo) error

ParseNum parses s and populates NumInfo with the result.

func Unquote ¶

func Unquote(s string) (string, error)

Unquote interprets s as a single- or double-quoted, single- or multi-line string, possibly with custom escape delimiters, returning the string value that s quotes.

Types ¶

type Multiplier ¶

type Multiplier byte

A Multiplier indicates a multiplier indicator used in the literal.

type NumInfo ¶

type NumInfo struct {
	UseSep bool
	// contains filtered or unexported fields
}

NumInfo contains information about a parsed numbers.

Reusing a NumInfo across parses may avoid memory allocations.

func (*NumInfo) Decimal ¶

func (p *NumInfo) Decimal(v *decimal) error

Decimal is for internal use.

func (*NumInfo) IsInt ¶

func (p *NumInfo) IsInt() bool

IsInt reports whether the number is an integral number.

func (*NumInfo) Multiplier ¶

func (p *NumInfo) Multiplier() Multiplier

Multiplier reports which multiplier was used in an integral number.

func (*NumInfo) String ¶

func (p *NumInfo) String() string

String returns a canonical string representation of the number so that it can be parsed with math.Float.Parse.

type QuoteInfo ¶

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

QuoteInfo describes the type of quotes used for a string.

func ParseQuotes ¶

func ParseQuotes(start, end string) (q QuoteInfo, nStart, nEnd int, err error)

ParseQuotes checks if the opening quotes in start matches the ending quotes in end and reports its type as q or an error if they do not matching or are invalid. nStart indicates the number of bytes used for the opening quote.

func (QuoteInfo) IsDouble ¶

func (q QuoteInfo) IsDouble() bool

IsDouble reports whether the literal uses double quotes.

func (QuoteInfo) Unquote ¶

func (q QuoteInfo) Unquote(s string) (string, error)

Unquote unquotes the given string. It must be terminated with a quote or an interpolation start. Escape sequences are expanded and surrogates are replaced with the corresponding non-surrogate code points.
