README

Exercise 12.8 (P347)

The sexpr.Unmarshal function, like json.Marshal, requires the complete input in a byte slice before it can begin decoding. Define a sexpr.Decoder type that, like json.Decoder, allows a sequence of values to be decoded from an io.reader. Change sexpr.Unmarshal to use this new type.

Documentation

Overview

Package sexpr provides a means for converting Go objects to and from S-expressions.

Functions

func Marshal

func Marshal(v interface{}) ([]byte, error)

Marshal encodes a Go value in S-expression form.

func Unmarshal

func Unmarshal(data []byte, out interface{}) (err error)

Unmarshal parses S-expression data and populates the variable whose address is in the non-nil pointer out.

Types

type Decoder

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

func NewDecoder

func NewDecoder(r io.Reader) *Decoder

func (*Decoder) Decode

func (d *Decoder) Decode(v interface{}) (err error)

func (*Decoder) More

func (d *Decoder) More() bool
