    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.
