Summary

Provides a low-level interface to the encoding/json package.

Package json implements encoding and decoding of JSON as defined in
RFC 7159. The mapping between JSON and Go values is described
in the documentation for the Marshal and Unmarshal functions.

See "JSON and Go" for an introduction to this package:
https://golang.org/doc/articles/json_and_go.html

Constants

Constants are variables with :const true in their metadata. Joker currently does not recognize them as special; as such, it allows redefining them or their values.

Functions, Macros, and Special Forms

• Compact

  Function v1.0

  (Compact dst src)
  

  Compact appends to dst the JSON-encoded src with
  insignificant space characters elided.
  
  Go input arguments: (dst *bytes.Buffer, src []byte)
  
  Go returns: error
  
  Joker input arguments: [^go.std.bytes/*Buffer dst, ^arrayOfByte src]
  
  Joker returns: ^Error

• HTMLEscape

  Function v1.0

  (HTMLEscape dst src)
  

  HTMLEscape appends to dst the JSON-encoded src with <, >, &, U+2028 and U+2029
  characters inside string literals changed to \u003c, \u003e, \u0026, \u2028, \u2029
  so that the JSON will be safe to embed inside HTML <script> tags.
  For historical reasons, web browsers don't honor standard HTML
  escaping within <script> tags, so an alternative JSON encoding must
  be used.
  
  Go input arguments: (dst *bytes.Buffer, src []byte)
  
  Joker input arguments: [^go.std.bytes/*Buffer dst, ^arrayOfByte src]

• Indent

  Function v1.0

  (Indent dst src prefix indent)
  

  Indent appends to dst an indented form of the JSON-encoded src.
  Each element in a JSON object or array begins on a new,
  indented line beginning with prefix followed by one or more
  copies of indent according to the indentation nesting.
  The data appended to dst does not begin with the prefix nor
  any indentation, to make it easier to embed inside other formatted JSON data.
  Although leading space characters (space, tab, carriage return, newline)
  at the beginning of src are dropped, trailing space characters
  at the end of src are preserved and copied to dst.
  For example, if src has no trailing spaces, neither will dst;
  if src ends in a trailing newline, so will dst.
  
  Go input arguments: (dst *bytes.Buffer, src []byte, prefix string, indent string)
  
  Go returns: error
  
  Joker input arguments: [^go.std.bytes/*Buffer dst, ^arrayOfByte src, ^String prefix, ^String indent]
  
  Joker returns: ^Error

• Marshal

  Function v1.0

  (Marshal v)
  

  Marshal returns the JSON encoding of v.
  
  Marshal traverses the value v recursively.
  If an encountered value implements the Marshaler interface
  and is not a nil pointer, Marshal calls its MarshalJSON method
  to produce JSON. If no MarshalJSON method is present but the
  value implements encoding.TextMarshaler instead, Marshal calls
  its MarshalText method and encodes the result as a JSON string.
  The nil pointer exception is not strictly necessary
  but mimics a similar, necessary exception in the behavior of
  UnmarshalJSON.
  
  Otherwise, Marshal uses the following type-dependent default encodings:
  
  Boolean values encode as JSON booleans.
  
  Floating point, integer, and Number values encode as JSON numbers.
  
  String values encode as JSON strings coerced to valid UTF-8,
  replacing invalid bytes with the Unicode replacement rune.
  So that the JSON will be safe to embed inside HTML <script> tags,
  the string is encoded using HTMLEscape,
  which replaces "<", ">", "&", U+2028, and U+2029 are escaped
  to "\u003c","\u003e", "\u0026", "\u2028", and "\u2029".
  This replacement can be disabled when using an Encoder,
  by calling SetEscapeHTML(false).
  
  Array and slice values encode as JSON arrays, except that
  []byte encodes as a base64-encoded string, and a nil slice
  encodes as the null JSON value.
  
  Struct values encode as JSON objects.
  Each exported struct field becomes a member of the object, using the
  field name as the object key, unless the field is omitted for one of the
  reasons given below.
  
  The encoding of each struct field can be customized by the format string
  stored under the "json" key in the struct field's tag.
  The format string gives the name of the field, possibly followed by a
  comma-separated list of options. The name may be empty in order to
  specify options without overriding the default field name.
  
  The "omitempty" option specifies that the field should be omitted
  from the encoding if the field has an empty value, defined as
  false, 0, a nil pointer, a nil interface value, and any empty array,
  slice, map, or string.
  
  As a special case, if the field tag is "-", the field is always omitted.
  Note that a field with name "-" can still be generated using the tag "-,".
  
  Examples of struct field tags and their meanings:
  
  // Field appears in JSON as key "myName".
  Field int `json:"myName"`
  
  // Field appears in JSON as key "myName" and
  // the field is omitted from the object if its value is empty,
  // as defined above.
  Field int `json:"myName,omitempty"`
  
  // Field appears in JSON as key "Field" (the default), but
  // the field is skipped if empty.
  // Note the leading comma.
  Field int `json:",omitempty"`
  
  // Field is ignored by this package.
  Field int `json:"-"`
  
  // Field appears in JSON as key "-".
  Field int `json:"-,"`
  
  The "string" option signals that a field is stored as JSON inside a
  JSON-encoded string. It applies only to fields of string, floating point,
  integer, or boolean types. This extra level of encoding is sometimes used
  when communicating with JavaScript programs:
  
  Int64String int64 `json:",string"`
  
  The key name will be used if it's a non-empty string consisting of
  only Unicode letters, digits, and ASCII punctuation except quotation
  marks, backslash, and comma.
  
  Anonymous struct fields are usually marshaled as if their inner exported fields
  were fields in the outer struct, subject to the usual Go visibility rules amended
  as described in the next paragraph.
  An anonymous struct field with a name given in its JSON tag is treated as
  having that name, rather than being anonymous.
  An anonymous struct field of interface type is treated the same as having
  that type as its name, rather than being anonymous.
  
  The Go visibility rules for struct fields are amended for JSON when
  deciding which field to marshal or unmarshal. If there are
  multiple fields at the same level, and that level is the least
  nested (and would therefore be the nesting level selected by the
  usual Go rules), the following extra rules apply:
  
  1) Of those fields, if any are JSON-tagged, only tagged fields are considered,
  even if there are multiple untagged fields that would otherwise conflict.
  
  2) If there is exactly one field (tagged or not according to the first rule), that is selected.
  
  3) Otherwise there are multiple fields, and all are ignored; no error occurs.
  
  Handling of anonymous struct fields is new in Go 1.1.
  Prior to Go 1.1, anonymous struct fields were ignored. To force ignoring of
  an anonymous struct field in both current and earlier versions, give the field
  a JSON tag of "-".
  
  Map values encode as JSON objects. The map's key type must either be a
  string, an integer type, or implement encoding.TextMarshaler. The map keys
  are sorted and used as JSON object keys by applying the following rules,
  subject to the UTF-8 coercion described for string values above:
  - keys of any string type are used directly
  - encoding.TextMarshalers are marshaled
  - integer keys are converted to strings
  
  Pointer values encode as the value pointed to.
  A nil pointer encodes as the null JSON value.
  
  Interface values encode as the value contained in the interface.
  A nil interface value encodes as the null JSON value.
  
  Channel, complex, and function values cannot be encoded in JSON.
  Attempting to encode such a value causes Marshal to return
  an UnsupportedTypeError.
  
  JSON cannot represent cyclic data structures and Marshal does not
  handle them. Passing cyclic structures to Marshal will result in
  an error.
  
  Go input arguments: (v any)
  
  Go returns: ([]byte, error)
  
  Joker input arguments: [^GoObject v]
  
  Joker returns: [^arrayOfByte, ^Error]

• MarshalIndent

  Function v1.0

  (MarshalIndent v prefix indent)
  

  MarshalIndent is like Marshal but applies Indent to format the output.
  Each JSON element in the output will begin on a new line beginning with prefix
  followed by one or more copies of indent according to the indentation nesting.
  
  Go input arguments: (v any, prefix string, indent string)
  
  Go returns: ([]byte, error)
  
  Joker input arguments: [^GoObject v, ^String prefix, ^String indent]
  
  Joker returns: [^arrayOfByte, ^Error]

• NewDecoder

  Function v1.0

  (NewDecoder r)
  

  NewDecoder returns a new decoder that reads from r.
  
  The decoder introduces its own buffering and may
  read data from r beyond the JSON values requested.
  
  Go input arguments: (r io.Reader)
  
  Go returns: *Decoder
  
  Joker input arguments: [^go.std.io/Reader r]
  
  Joker returns: ^*Decoder

• NewEncoder

  Function v1.0

  (NewEncoder w)
  

  NewEncoder returns a new encoder that writes to w.
  
  Go input arguments: (w io.Writer)
  
  Go returns: *Encoder
  
  Joker input arguments: [^go.std.io/Writer w]
  
  Joker returns: ^*Encoder

• Unmarshal

  Function v1.0

  (Unmarshal data v)
  

  Unmarshal parses the JSON-encoded data and stores the result
  in the value pointed to by v. If v is nil or not a pointer,
  Unmarshal returns an InvalidUnmarshalError.
  
  Unmarshal uses the inverse of the encodings that
  Marshal uses, allocating maps, slices, and pointers as necessary,
  with the following additional rules:
  
  To unmarshal JSON into a pointer, Unmarshal first handles the case of
  the JSON being the JSON literal null. In that case, Unmarshal sets
  the pointer to nil. Otherwise, Unmarshal unmarshals the JSON into
  the value pointed at by the pointer. If the pointer is nil, Unmarshal
  allocates a new value for it to point to.
  
  To unmarshal JSON into a value implementing the Unmarshaler interface,
  Unmarshal calls that value's UnmarshalJSON method, including
  when the input is a JSON null.
  Otherwise, if the value implements encoding.TextUnmarshaler
  and the input is a JSON quoted string, Unmarshal calls that value's
  UnmarshalText method with the unquoted form of the string.
  
  To unmarshal JSON into a struct, Unmarshal matches incoming object
  keys to the keys used by Marshal (either the struct field name or its tag),
  preferring an exact match but also accepting a case-insensitive match. By
  default, object keys which don't have a corresponding struct field are
  ignored (see Decoder.DisallowUnknownFields for an alternative).
  
  To unmarshal JSON into an interface value,
  Unmarshal stores one of these in the interface value:
  
  bool, for JSON booleans
  float64, for JSON numbers
  string, for JSON strings
  []interface{}, for JSON arrays
  map[string]interface{}, for JSON objects
  nil for JSON null
  
  To unmarshal a JSON array into a slice, Unmarshal resets the slice length
  to zero and then appends each element to the slice.
  As a special case, to unmarshal an empty JSON array into a slice,
  Unmarshal replaces the slice with a new empty slice.
  
  To unmarshal a JSON array into a Go array, Unmarshal decodes
  JSON array elements into corresponding Go array elements.
  If the Go array is smaller than the JSON array,
  the additional JSON array elements are discarded.
  If the JSON array is smaller than the Go array,
  the additional Go array elements are set to zero values.
  
  To unmarshal a JSON object into a map, Unmarshal first establishes a map to
  use. If the map is nil, Unmarshal allocates a new map. Otherwise Unmarshal
  reuses the existing map, keeping existing entries. Unmarshal then stores
  key-value pairs from the JSON object into the map. The map's key type must
  either be any string type, an integer, implement json.Unmarshaler, or
  implement encoding.TextUnmarshaler.
  
  If a JSON value is not appropriate for a given target type,
  or if a JSON number overflows the target type, Unmarshal
  skips that field and completes the unmarshaling as best it can.
  If no more serious errors are encountered, Unmarshal returns
  an UnmarshalTypeError describing the earliest such error. In any
  case, it's not guaranteed that all the remaining fields following
  the problematic one will be unmarshaled into the target object.
  
  The JSON null value unmarshals into an interface, map, pointer, or slice
  by setting that Go value to nil. Because null is often used in JSON to mean
  ``not present,'' unmarshaling a JSON null into any other Go type has no effect
  on the value and produces no error.
  
  When unmarshaling quoted strings, invalid UTF-8 or
  invalid UTF-16 surrogate pairs are not treated as an error.
  Instead, they are replaced by the Unicode replacement
  character U+FFFD.

  Concrete Type v1.0

  A Decoder reads and decodes JSON values from an input stream.
  

• Buffered

  Receiver for *Decoder v1.0

  ([])
  

  Buffered returns a reader of the data remaining in the Decoder's
  buffer. The reader is valid until the next call to Decode.
  

• Decode

  Receiver for *Decoder v1.0

  ([v])
  

  Decode reads the next JSON-encoded value from its
  input and stores it in the value pointed to by v.
  
  See the documentation for Unmarshal for details about
  the conversion of JSON into a Go value.
  

• DisallowUnknownFields

  Receiver for *Decoder v1.0

  ([])
  

  DisallowUnknownFields causes the Decoder to return an error when the destination
  is a struct and the input contains object keys which do not match any
  non-ignored, exported fields in the destination.
  

• InputOffset

  Receiver for *Decoder v1.0

  ([])
  

  InputOffset returns the input stream byte offset of the current decoder position.
  The offset gives the location of the end of the most recently returned token
  and the beginning of the next token.
  

• More

  Receiver for *Decoder v1.0

  ([])
  

  More reports whether there is another element in the
  current array or object being parsed.
  

• Token

  Receiver for *Decoder v1.0

  ([])
  

  Token returns the next JSON token in the input stream.
  At the end of the input stream, Token returns nil, io.EOF.
  
  Token guarantees that the delimiters [ ] { } it returns are
  properly nested and matched: if Token encounters an unexpected
  delimiter in the input, it will return an error.
  
  The input stream consists of basic JSON values—bool, string,
  number, and null—along with delimiters [ ] { } of type Delim
  to mark the start and end of arrays and objects.
  Commas and colons are elided.
  

• UseNumber

  Receiver for *Decoder v1.0

  ([])
  

  UseNumber causes the Decoder to unmarshal a number into an interface{} as a
  Number instead of as a float64.

  A Delim is a JSON array or object delimiter, one of [ ] { or }.
  

• *Encoder

  Concrete Type v1.0

  An Encoder writes JSON values to an output stream.

  followed by a newline character.
  
  See the documentation for Marshal for details about the
  conversion of Go values to JSON.
  

• SetEscapeHTML

  Receiver for *Encoder v1.0

  ([on])
  

  SetEscapeHTML specifies whether problematic HTML characters
  should be escaped inside JSON quoted strings.
  The default behavior is to escape &, <, and > to \u0026, \u003c, and \u003e
  to avoid certain safety problems that can arise when embedding JSON in HTML.
  
  In non-HTML settings where the escaping interferes with the readability
  of the output, SetEscapeHTML(false) disables this behavior.
  

• SetIndent

  Receiver for *Encoder v1.0

  ([prefix indent])
  

  SetIndent instructs the encoder to format each subsequent encoded
  value as if indented by the package-level function Indent(dst, src, prefix, indent).
  Calling SetIndent("", "") disables indentation.
  

• *InvalidUTF8Error

  Concrete Type v1.0

  Before Go 1.2, an InvalidUTF8Error was returned by Marshal when
  attempting to encode a string value with invalid UTF-8 sequences.
  As of Go 1.2, Marshal instead coerces the string to valid UTF-8 by
  replacing invalid bytes with the Unicode replacement rune U+FFFD.
