Revision history for Perl extension JSON.
-## TRANSITION PLAN ######################################################
+## JSON version 2.9 #####################################################
-In the next large update version, JSON and JSONRPC modules are split.
+CAUTION!!!
+INCOMPATIBLE CHANGE
- JSON::Parser and JSON::Converter are deleted from JSON dist.
- JSON and JSON::PP in JSON dist.
+JSON.pm had patched JSON::XS::Boolean and JSON::PP::Boolean internally
+on loading time for making these modules inherit JSON::Boolean.
+But since JSON::XS v3.0 it use Types::Serialiser as boolean class.
+Then now JSON.pm breaks boolean classe overload features and
+-support_by_pp if JSON::XS v3.0 or later is installed.
- JSON becomes wrapper to JSON::XS and/or JSON::PP.
+JSON::true and JSON::false returned JSON::Boolean objects.
+For workaround, they return JSON::PP::Boolean objects in this version.
- JSONRPC* and Apache::JSONRPC are deleted from JSON dist.
- JSONRPC::Client, JSONRPC::Server and JSONRPC::Procedure in JSON::RPC dist.
+ isa_ok(JSON::true, 'JSON::PP::Boolean');
- Modules in JSON::RPC dist supports JSONRPC protocol v1.1 and 1.0.
+And it discards a feature:
+
+ ok(JSON::true eq 'true');
+
+In other word, JSON::PP::Boolean overload numeric only.
+
+ ok( JSON::true == 1 );

+
+ JSON (JavaScript Object Notation) is a simple data format. See to
+ <http://www.json.org/> and
+ "RFC4627"(<http://www.ietf.org/rfc/rfc4627.txt>).
+
+ This module converts Perl data structures to JSON and vice versa using
+ either JSON::XS or JSON::PP.
+
+ JSON::XS is the fastest and most proper JSON module on CPAN which must
+ be compiled and installed in your environment. JSON::PP is a pure-Perl
+ module which is bundled in this distribution and has a strong
+ compatibility to JSON::XS.
+
+ This module try to use JSON::XS by default and fail to it, use JSON::PP
+ instead. So its features completely depend on JSON::XS or JSON::PP.
+
+ See to "BACKEND MODULE DECISION".
+
+ To distinguish the module name 'JSON' and the format type JSON, the
+ former is quoted by C<> (its results vary with your using media), and
+ the latter is left just as it is.
+
+ Module name : "JSON"
+
+ Format type : JSON
+
+ FEATURES
+ * correct unicode handling
+
+ This module (i.e. backend modules) knows how to handle Unicode,
+ documents how and when it does so, and even documents what "correct"
+ means.
+
+ Even though there are limitations, this feature is available since
+ Perl version 5.6.
+
+ JSON::XS requires Perl 5.8.2 (but works correctly in 5.8.8 or
+ later), so in older versions "JSON" should call JSON::PP as the
+ backend which can be used since Perl 5.005.
+
+ With Perl 5.8.x JSON::PP works, but from 5.8.0 to 5.8.2, because of
+ a Perl side problem, JSON::PP works slower in the versions. And in
+ 5.005, the Unicode handling is not available. See to "UNICODE
+ HANDLING ON PERLS" in JSON::PP for more information.
+
+ See also to "A FEW NOTES ON UNICODE AND PERL" in JSON::XS and
+ "ENCODING/CODESET_FLAG_NOTES" in JSON::XS.
+
+ * round-trip integrity
+
+ When you serialise a perl data structure using only data types
+ supported by JSON and Perl, the deserialised data structure is
+ identical on the Perl level. (e.g. the string "2.0" doesn't suddenly
+ become "2" just because it looks like a number). There *are* minor
+ exceptions to this, read the "MAPPING" section below to learn about
+ those.
+
+ * strict checking of JSON correctness
+
+ There is no guessing, no generating of illegal JSON texts by
+ default, and only JSON is accepted as input by default (the latter
+ is a security feature).
+
+ See to "FEATURES" in JSON::XS and "FEATURES" in JSON::PP.
+
+ * fast
+
+ This module returns a JSON::XS object itself if available. Compared
+ to other JSON modules and other serialisers such as Storable,
+ JSON::XS usually compares favorably in terms of speed, too.
+
+ If not available, "JSON" returns a JSON::PP object instead of
+ JSON::XS and it is very slow as pure-Perl.
+
+ * simple to use
+
+ This module has both a simple functional interface as well as an
+ object oriented interface interface.
+
+ * reasonably versatile output formats
+
+ You can choose between the most compact guaranteed-single-line
+ format possible (nice for simple line-based protocols), a pure-ASCII
+ format (for when your transport is not 8-bit clean, still supports
+ the whole Unicode range), or a pretty-printed format (for when you
+ want to read that stuff). Or you can combine those features in
+ whatever way you like.
+
+FUNCTIONAL INTERFACE
+ Some documents are copied and modified from "FUNCTIONAL INTERFACE" in
+ JSON::XS. "to_json" and "from_json" are additional functions.
+
+ encode_json
+ $json_text = encode_json $perl_scalar
+
+ Converts the given Perl data structure to a UTF-8 encoded, binary
+ string.
+
+ This function call is functionally identical to:
+
+ $json_text = JSON->new->utf8->encode($perl_scalar)
+
+ decode_json
+ $perl_scalar = decode_json $json_text
+
+ The opposite of "encode_json": expects an UTF-8 (binary) string and
+ tries to parse that as an UTF-8 encoded JSON text, returning the
+ resulting reference.
+
+ This function call is functionally identical to:
+
+ $perl_scalar = JSON->new->utf8->decode($json_text)
+
+ to_json
+ $json_text = to_json($perl_scalar)
+
+ Converts the given Perl data structure to a json string.
+
+ This function call is functionally identical to:
+
+ $json_text = JSON->new->encode($perl_scalar)
+
+ Takes a hash reference as the second.
+
+ $json_text = to_json($perl_scalar, $flag_hashref)
+
+ So,
+
+ $json_text = to_json($perl_scalar, {utf8 => 1, pretty => 1})
+
+ equivalent to:
+
+ $json_text = JSON->new->utf8(1)->pretty(1)->encode($perl_scalar)
+
+ If you want to write a modern perl code which communicates to outer
+ world, you should use "encode_json" (supposed that JSON data are encoded
+ in UTF-8).
+
+ from_json
+ $perl_scalar = from_json($json_text)
+
+ The opposite of "to_json": expects a json string and tries to parse it,
+ returning the resulting reference.
+
+ This function call is functionally identical to:
+
+ $perl_scalar = JSON->decode($json_text)
+
+ Takes a hash reference as the second.
+
+ $perl_scalar = from_json($json_text, $flag_hashref)
+
+ So,
+
+ $perl_scalar = from_json($json_text, {utf8 => 1})
+
+ equivalent to:
+
+ $perl_scalar = JSON->new->utf8(1)->decode($json_text)
+
+ If you want to write a modern perl code which communicates to outer
+ world, you should use "decode_json" (supposed that JSON data are encoded
+ in UTF-8).
+
+ JSON::is_bool
+ $is_boolean = JSON::is_bool($scalar)
+
+ Returns true if the passed scalar represents either JSON::true or
+ JSON::false, two constants that act like 1 and 0 respectively and are
+ also used to represent JSON "true" and "false" in Perl strings.
+
+ JSON::true
+ Returns JSON true value which is blessed object. It "isa" JSON::Boolean
+ object.
+
+ JSON::false
+ Returns JSON false value which is blessed object. It "isa" JSON::Boolean
+ object.
+
+ JSON::null
+ Returns "undef".
+
+ See MAPPING, below, for more information on how JSON values are mapped
+ to Perl.
+
+HOW DO I DECODE A DATA FROM OUTER AND ENCODE TO OUTER
+ This section supposes that your perl version is 5.8 or later.
+
+ If you know a JSON text from an outer world - a network, a file content,
+ and so on, is encoded in UTF-8, you should use "decode_json" or "JSON"
+ module object with "utf8" enable. And the decoded result will contain
+ UNICODE characters.
+
+ # from network
+ my $json = JSON->new->utf8;
+ my $json_text = CGI->new->param( 'json_data' );
+ my $perl_scalar = $json->decode( $json_text );
+
+ # from file content
+ local $/;
+ open( my $fh, '<', 'json.data' );
+ $json_text = <$fh>;
+ $perl_scalar = decode_json( $json_text );
+
+ If an outer data is not encoded in UTF-8, firstly you should "decode"
+ it.
+
+ use Encode;
+ local $/;
+ open( my $fh, '<', 'json.data' );
+ my $encoding = 'cp932';
+ my $unicode_json_text = decode( $encoding, <$fh> ); # UNICODE
+
+ # or you can write the below code.
+ #
+ # open( my $fh, "<:encoding($encoding)", 'json.data' );
+ # $unicode_json_text = <$fh>;
+
+ In this case, $unicode_json_text is of course UNICODE string. So you
+ cannot use "decode_json" nor "JSON" module object with "utf8" enable.
+ Instead of them, you use "JSON" module object with "utf8" disable or
+ "from_json".
+
+ $perl_scalar = $json->utf8(0)->decode( $unicode_json_text );
+ # or
+ $perl_scalar = from_json( $unicode_json_text );
+
+ Or "encode 'utf8'" and "decode_json":
+
+ $perl_scalar = decode_json( encode( 'utf8', $unicode_json_text ) );
+ # this way is not efficient.
+
+ And now, you want to convert your $perl_scalar into JSON data and send
+ it to an outer world - a network or a file content, and so on.
+
+ Your data usually contains UNICODE strings and you want the converted
+ data to be encoded in UTF-8, you should use "encode_json" or "JSON"
+ module object with "utf8" enable.
+
+ print encode_json( $perl_scalar ); # to a network? file? or display?
+ # or
+ print $json->utf8->encode( $perl_scalar );
+
+ If $perl_scalar does not contain UNICODE but $encoding-encoded strings
+ for some reason, then its characters are regarded as latin1 for perl
+ (because it does not concern with your $encoding). You cannot use
+ "encode_json" nor "JSON" module object with "utf8" enable. Instead of
+ them, you use "JSON" module object with "utf8" disable or "to_json".
+ Note that the resulted text is a UNICODE string but no problem to print
+ it.
+
+ # $perl_scalar contains $encoding encoded string values
+ $unicode_json_text = $json->utf8(0)->encode( $perl_scalar );
+ # or
+ $unicode_json_text = to_json( $perl_scalar );
+ # $unicode_json_text consists of characters less than 0x100
+ print $unicode_json_text;
+
+ Or "decode $encoding" all string values and "encode_json":
+
+ $perl_scalar->{ foo } = decode( $encoding, $perl_scalar->{ foo } );
+ # ... do it to each string values, then encode_json
+ $json_text = encode_json( $perl_scalar );
+
+ This method is a proper way but probably not efficient.
+
+ See to Encode, perluniintro.
+
+COMMON OBJECT-ORIENTED INTERFACE
+ new
+ $json = JSON->new
+
+ Returns a new "JSON" object inherited from either JSON::XS or JSON::PP
+ that can be used to de/encode JSON strings.
+
+ All boolean flags described below are by default *disabled*.
+
+ The mutators for flags all return the JSON object again and thus calls
+ can be chained:
+
+ my $json = JSON->new->utf8->space_after->encode({a => [1,2]})
+ => {"a": [1, 2]}
+
+ ascii
+ $json = $json->ascii([$enable])
+
+ $enabled = $json->get_ascii
+
+ If $enable is true (or missing), then the encode method will not
+ generate characters outside the code range 0..127. Any Unicode
+ characters outside that range will be escaped using either a single
+ \uXXXX or a double \uHHHH\uLLLLL escape sequence, as per RFC4627.
+
+ If $enable is false, then the encode method will not escape Unicode
+ characters unless required by the JSON syntax or other flags. This
+ results in a faster and more compact format.
+
+ This feature depends on the used Perl version and environment.
+
+ See to "UNICODE HANDLING ON PERLS" in JSON::PP if the backend is PP.
+
+ JSON->new->ascii(1)->encode([chr 0x10401])
+ => ["\ud801\udc01"]
+
+ latin1
+ $json = $json->latin1([$enable])
+
+ $enabled = $json->get_latin1
+
+ If $enable is true (or missing), then the encode method will encode the
+ resulting JSON text as latin1 (or iso-8859-1), escaping any characters
+ outside the code range 0..255.
+
+ If $enable is false, then the encode method will not escape Unicode
+ characters unless required by the JSON syntax or other flags.
+
+ JSON->new->latin1->encode (["\x{89}\x{abc}"]
+ => ["\x{89}\\u0abc"] # (perl syntax, U+abc escaped, U+89 not)
+
+ utf8
+ $json = $json->utf8([$enable])
+
+ $enabled = $json->get_utf8
+
+ If $enable is true (or missing), then the encode method will encode the
+ JSON result into UTF-8, as required by many protocols, while the decode
+ method expects to be handled an UTF-8-encoded string. Please note that
+ UTF-8-encoded strings do not contain any characters outside the range
+ 0..255, they are thus useful for bytewise/binary I/O.
+
+ In future versions, enabling this option might enable autodetection of
+ the UTF-16 and UTF-32 encoding families, as described in RFC4627.
+
+ If $enable is false, then the encode method will return the JSON string
+ as a (non-encoded) Unicode string, while decode expects thus a Unicode
+ string. Any decoding or encoding (e.g. to UTF-8 or UTF-16) needs to be
+ done yourself, e.g. using the Encode module.
+
+ Example, output UTF-16BE-encoded JSON:
+
+ use Encode;
+ $jsontext = encode "UTF-16BE", JSON::XS->new->encode ($object);
+
+ Example, decode UTF-32LE-encoded JSON:
+
+ use Encode;
+ $object = JSON::XS->new->decode (decode "UTF-32LE", $jsontext);
+
+ See to "UNICODE HANDLING ON PERLS" in JSON::PP if the backend is PP.
+
+ pretty
+ $json = $json->pretty([$enable])
+
+ This enables (or disables) all of the "indent", "space_before" and
+ "space_after" (and in the future possibly more) flags in one call to
+ generate the most readable (or most compact) form possible.
+
+ Equivalent to:
+
+ $json->indent->space_before->space_after
+
+ The indent space length is three and JSON::XS cannot change the indent
+ space length.
+
+ indent
+ $json = $json->indent([$enable])
+
+ $enabled = $json->get_indent
+
+ If $enable is true (or missing), then the "encode" method will use a
+ multiline format as output, putting every array member or object/hash
+ key-value pair into its own line, identifying them properly.
+
+ If $enable is false, no newlines or indenting will be produced, and the
+ resulting JSON text is guaranteed not to contain any "newlines".
+
+ This setting has no effect when decoding JSON texts.
+
+ The indent space length is three. With JSON::PP, you can also access
+ "indent_length" to change indent space length.
+
+ space_before
+ $json = $json->space_before([$enable])
+
+ $enabled = $json->get_space_before
+
+ If $enable is true (or missing), then the "encode" method will add an
+ extra optional space before the ":" separating keys from values in JSON
+ objects.
+
+ If $enable is false, then the "encode" method will not add any extra
+ space at those places.
+
+ This setting has no effect when decoding JSON texts.
+
+ Example, space_before enabled, space_after and indent disabled:
+
+ {"key" :"value"}
+
+ space_after
+ $json = $json->space_after([$enable])
+
+ $enabled = $json->get_space_after
+
+ If $enable is true (or missing), then the "encode" method will add an
+ extra optional space after the ":" separating keys from values in JSON
+ objects and extra whitespace after the "," separating key-value pairs
+ and array members.
+
+ If $enable is false, then the "encode" method will not add any extra
+ space at those places.
+
+ This setting has no effect when decoding JSON texts.
+
+ Example, space_before and indent disabled, space_after enabled:
+
+ {"key": "value"}
+
+ relaxed
+ $json = $json->relaxed([$enable])
+
+ $enabled = $json->get_relaxed
+
+ If $enable is true (or missing), then "decode" will accept some
+ extensions to normal JSON syntax (see below). "encode" will not be
+ affected in anyway. *Be aware that this option makes you accept invalid
+ JSON texts as if they were valid!*. I suggest only to use this option to
+ parse application-specific files written by humans (configuration files,
+ resource files etc.)
+
+ If $enable is false (the default), then "decode" will only accept valid
+ JSON texts.
+
+ Currently accepted extensions are:
+
+ * list items can have an end-comma
+
+ JSON *separates* array elements and key-value pairs with commas.
+ This can be annoying if you write JSON texts manually and want to be
+ able to quickly append elements, so this extension accepts comma at
+ the end of such items not just between them:
+
+ [
+ 1,
+ 2, <- this comma not normally allowed
+ ]
+ {
+ "k1": "v1",
+ "k2": "v2", <- this comma not normally allowed
+ }
+
+ * shell-style '#'-comments
+
+ Whenever JSON allows whitespace, shell-style comments are
+ additionally allowed. They are terminated by the first
+ carriage-return or line-feed character, after which more white-space
+ and comments are allowed.
+
+ [
+ 1, # this comment not allowed in JSON
+ # neither this one...
+ ]
+
+ canonical
+ $json = $json->canonical([$enable])
+
+ $enabled = $json->get_canonical
+
+ If $enable is true (or missing), then the "encode" method will output
+ JSON objects by sorting their keys. This is adding a comparatively high
+ overhead.
+
+ If $enable is false, then the "encode" method will output key-value
+ pairs in the order Perl stores them (which will likely change between
+ runs of the same script).
+
+ This option is useful if you want the same data structure to be encoded
+ as the same JSON text (given the same overall settings). If it is
+ disabled, the same hash might be encoded differently even if contains
+ the same data, as key-value pairs have no inherent ordering in Perl.
+
+ This setting has no effect when decoding JSON texts.
+
+ allow_nonref
+ $json = $json->allow_nonref([$enable])
+
+ $enabled = $json->get_allow_nonref
+
+ If $enable is true (or missing), then the "encode" method can convert a
+ non-reference into its corresponding string, number or null JSON value,
+ which is an extension to RFC4627. Likewise, "decode" will accept those
+ JSON values instead of croaking.
+
+ If $enable is false, then the "encode" method will croak if it isn't
+ passed an arrayref or hashref, as JSON texts must either be an object or
+ array. Likewise, "decode" will croak if given something that is not a
+ JSON object or array.
+
+ JSON->new->allow_nonref->encode ("Hello, World!")
+ => "Hello, World!"
+
+ allow_unknown
+ $json = $json->allow_unknown ([$enable])
+
+ $enabled = $json->get_allow_unknown
+
+ If $enable is true (or missing), then "encode" will *not* throw an
+ exception when it encounters values it cannot represent in JSON (for
+ example, filehandles) but instead will encode a JSON "null" value. Note
+ that blessed objects are not included here and are handled separately by
+ c<allow_nonref>.
+
+ If $enable is false (the default), then "encode" will throw an exception
+ when it encounters anything it cannot encode as JSON.
+
+ This option does not affect "decode" in any way, and it is recommended
+ to leave it off unless you know your communications partner.
+
+ allow_blessed
+ $json = $json->allow_blessed([$enable])
+
+ $enabled = $json->get_allow_blessed
+
+ If $enable is true (or missing), then the "encode" method will not barf
+ when it encounters a blessed reference. Instead, the value of the
+ convert_blessed option will decide whether "null" ("convert_blessed"
+ disabled or no "TO_JSON" method found) or a representation of the object
+ ("convert_blessed" enabled and "TO_JSON" method found) is being encoded.
+ Has no effect on "decode".
+
+ If $enable is false (the default), then "encode" will throw an exception
+ when it encounters a blessed object.
+
+ convert_blessed
+ $json = $json->convert_blessed([$enable])
+
+ $enabled = $json->get_convert_blessed
+
+ If $enable is true (or missing), then "encode", upon encountering a
+ blessed object, will check for the availability of the "TO_JSON" method
+ on the object's class. If found, it will be called in scalar context and
+ the resulting scalar will be encoded instead of the object. If no
+ "TO_JSON" method is found, the value of "allow_blessed" will decide what
+ to do.
+
+ The "TO_JSON" method may safely call die if it wants. If "TO_JSON"
+ returns other blessed objects, those will be handled in the same way.
+ "TO_JSON" must take care of not causing an endless recursion cycle (==
+ crash) in this case. The name of "TO_JSON" was chosen because other
+ methods called by the Perl core (== not by the user of the object) are
+ usually in upper case letters and to avoid collisions with the "to_json"
+ function or method.
+
+ This setting does not yet influence "decode" in any way.
+
+ If $enable is false, then the "allow_blessed" setting will decide what
+ to do when a blessed object is found.
+
+ convert_blessed_universally mode
+ If use "JSON" with "-convert_blessed_universally", the
+ "UNIVERSAL::TO_JSON" subroutine is defined as the below code:
+
+ *UNIVERSAL::TO_JSON = sub {
+ my $b_obj = B::svref_2object( $_[0] );
+ return $b_obj->isa('B::HV') ? { %{ $_[0] } }
+ : $b_obj->isa('B::AV') ? [ @{ $_[0] } ]
+ : undef
+ ;
+ }
+
+ This will cause that "encode" method converts simple blessed objects
+ into JSON objects as non-blessed object.
+
+ JSON -convert_blessed_universally;
+ $json->allow_blessed->convert_blessed->encode( $blessed_object )
+
+ This feature is experimental and may be removed in the future.
+
+ filter_json_object
+ $json = $json->filter_json_object([$coderef])
+
+ When $coderef is specified, it will be called from "decode" each time it
+ decodes a JSON object. The only argument passed to the coderef is a
+ reference to the newly-created hash. If the code references returns a
+ single scalar (which need not be a reference), this value (i.e. a copy
+ of that scalar to avoid aliasing) is inserted into the deserialised data
+ structure. If it returns an empty list (NOTE: *not* "undef", which is a
+ valid scalar), the original deserialised hash will be inserted. This
+ setting can slow down decoding considerably.
+
+ When $coderef is omitted or undefined, any existing callback will be
+ removed and "decode" will not change the deserialised hash in any way.
+
+ Example, convert all JSON objects into the integer 5:
+
+ my $js = JSON->new->filter_json_object (sub { 5 });
+ # returns [5]
+ $js->decode ('[{}]'); # the given subroutine takes a hash reference.
+ # throw an exception because allow_nonref is not enabled
+ # so a lone 5 is not allowed.
+ $js->decode ('{"a":1, "b":2}');
+
+ filter_json_single_key_object
+ $json = $json->filter_json_single_key_object($key [=> $coderef])
+
+ Works remotely similar to "filter_json_object", but is only called for
+ JSON objects having a single key named $key.
+
+ This $coderef is called before the one specified via
+ "filter_json_object", if any. It gets passed the single value in the
+ JSON object. If it returns a single value, it will be inserted into the
+ data structure. If it returns nothing (not even "undef" but the empty
+ list), the callback from "filter_json_object" will be called next, as if
+ no single-key callback were specified.
+
+ If $coderef is omitted or undefined, the corresponding callback will be
+ disabled. There can only ever be one callback for a given key.
+
+ As this callback gets called less often then the "filter_json_object"
+ one, decoding speed will not usually suffer as much. Therefore,
+ single-key objects make excellent targets to serialise Perl objects
+ into, especially as single-key JSON objects are as close to the
+ type-tagged value concept as JSON gets (it's basically an ID/VALUE
+ tuple). Of course, JSON does not support this in any way, so you need to
+ make sure your data never looks like a serialised Perl hash.
+
+ Typical names for the single object key are "__class_whatever__", or
+ "$__dollars_are_rarely_used__$" or "}ugly_brace_placement", or even
+ things like "__class_md5sum(classname)__", to reduce the risk of
+ clashing with real hashes.
+
+ Example, decode JSON objects of the form "{ "__widget__" => <id> }" into
+ the corresponding $WIDGET{<id>} object:
+
+ # return whatever is in $WIDGET{5}:
+ JSON
+ ->new
+ ->filter_json_single_key_object (__widget__ => sub {
+ $WIDGET{ $_[0] }
+ })
+ ->decode ('{"__widget__": 5')
+
+ # this can be used with a TO_JSON method in some "widget" class
+ # for serialisation to json:
+ sub WidgetBase::TO_JSON {
+ my ($self) = @_;
+
+ unless ($self->{id}) {
+ $self->{id} = ..get..some..id..;
+ $WIDGET{$self->{id}} = $self;
+ }
+
+ { __widget__ => $self->{id} }
+ }
+
+ shrink
+ $json = $json->shrink([$enable])
+
+ $enabled = $json->get_shrink
+
+ With JSON::XS, this flag resizes strings generated by either "encode" or
+ "decode" to their minimum size possible. This can save memory when your
+ JSON texts are either very very long or you have many short strings. It
+ will also try to downgrade any strings to octet-form if possible: perl
+ stores strings internally either in an encoding called UTF-X or in
+ octet-form. The latter cannot store everything but uses less space in
+ general (and some buggy Perl or C code might even rely on that internal
+ representation being used).
+
+ With JSON::PP, it is noop about resizing strings but tries
+ "utf8::downgrade" to the returned string by "encode". See to utf8.
+
+ See to "OBJECT-ORIENTED INTERFACE" in JSON::XS and "METHODS" in
+ JSON::PP.
+
+ max_depth
+ $json = $json->max_depth([$maximum_nesting_depth])
+
+ $max_depth = $json->get_max_depth
+
+ Sets the maximum nesting level (default 512) accepted while encoding or
+ decoding. If a higher nesting level is detected in JSON text or a Perl
+ data structure, then the encoder and decoder will stop and croak at that
+ point.
+
+ Nesting level is defined by number of hash- or arrayrefs that the
+ encoder needs to traverse to reach a given point or the number of "{" or
+ "[" characters without their matching closing parenthesis crossed to
+ reach a given character in a string.
+
+ If no argument is given, the highest possible setting will be used,
+ which is rarely useful.
+
+ Note that nesting is implemented by recursion in C. The default value
+ has been chosen to be as large as typical operating systems allow
+ without crashing. (JSON::XS)
+
+ With JSON::PP as the backend, when a large value (100 or more) was set
+ and it de/encodes a deep nested object/text, it may raise a warning
+ 'Deep recursion on subroutine' at the perl runtime phase.
+
+ See "SECURITY CONSIDERATIONS" in JSON::XS for more info on why this is
+ useful.
+
+ max_size
+ $json = $json->max_size([$maximum_string_size])
+
+ $max_size = $json->get_max_size
+
+ Set the maximum length a JSON text may have (in bytes) where decoding is
+ being attempted. The default is 0, meaning no limit. When "decode" is
+ called on a string that is longer then this many bytes, it will not
+ attempt to decode the string but throw an exception. This setting has no
+ effect on "encode" (yet).
+
+ If no argument is given, the limit check will be deactivated (same as
+ when 0 is specified).
+
+ See "SECURITY CONSIDERATIONS" in JSON::XS, below, for more info on why
+ this is useful.
+
+ encode
+ $json_text = $json->encode($perl_scalar)
+
+ Converts the given Perl data structure (a simple scalar or a reference
+ to a hash or array) to its JSON representation. Simple scalars will be
+ converted into JSON string or number sequences, while references to
+ arrays become JSON arrays and references to hashes become JSON objects.
+ Undefined Perl values (e.g. "undef") become JSON "null" values.
+ References to the integers 0 and 1 are converted into "true" and
+ "false".
+
+ decode
+ $perl_scalar = $json->decode($json_text)
+
+ The opposite of "encode": expects a JSON text and tries to parse it,
+ returning the resulting simple scalar or reference. Croaks on error.
+
+ JSON numbers and strings become simple Perl scalars. JSON arrays become
+ Perl arrayrefs and JSON objects become Perl hashrefs. "true" becomes 1
+ ("JSON::true"), "false" becomes 0 ("JSON::false") and "null" becomes
+ "undef".
+
+ decode_prefix
+ ($perl_scalar, $characters) = $json->decode_prefix($json_text)
+
+ This works like the "decode" method, but instead of raising an exception
+ when there is trailing garbage after the first JSON object, it will
+ silently stop parsing there and return the number of characters consumed
+ so far.
+
+ JSON->new->decode_prefix ("[1] the tail")
+ => ([], 3)
+
+ See to "OBJECT-ORIENTED INTERFACE" in JSON::XS
+
+ property
+ $boolean = $json->property($property_name)
+
+ Returns a boolean value about above some properties.
+
+ The available properties are "ascii", "latin1", "utf8",
+ "indent","space_before", "space_after", "relaxed", "canonical",
+ "allow_nonref", "allow_unknown", "allow_blessed", "convert_blessed",
+ "shrink", "max_depth" and "max_size".
+
+ $boolean = $json->property('utf8');
+ => 0
+ $json->utf8;
+ $boolean = $json->property('utf8');
+ => 1
+
+ Sets the property with a given boolean value.
+
+ $json = $json->property($property_name => $boolean);
+
+ With no argument, it returns all the above properties as a hash
+ reference.
+
+ $flag_hashref = $json->property();
+
+INCREMENTAL PARSING
+ Most of this section are copied and modified from "INCREMENTAL PARSING"
+ in JSON::XS.
+
+ In some cases, there is the need for incremental parsing of JSON texts.
+ This module does allow you to parse a JSON stream incrementally. It does
+ so by accumulating text until it has a full JSON object, which it then
+ can decode. This process is similar to using "decode_prefix" to see if a
+ full JSON object is available, but is much more efficient (and can be
+ implemented with a minimum of method calls).
+
+ The backend module will only attempt to parse the JSON text once it is
+ sure it has enough text to get a decisive result, using a very simple
+ but truly incremental parser. This means that it sometimes won't stop as
+ early as the full parser, for example, it doesn't detect parenthesis
+ mismatches. The only thing it guarantees is that it starts decoding as
+ soon as a syntactically valid JSON text has been seen. This means you
+ need to set resource limits (e.g. "max_size") to ensure the parser will
+ stop parsing in the presence if syntax errors.
+
+ The following methods implement this incremental parser.
+
+ incr_parse
+ $json->incr_parse( [$string] ) # void context
+
+ $obj_or_undef = $json->incr_parse( [$string] ) # scalar context
+
+ @obj_or_empty = $json->incr_parse( [$string] ) # list context
+
+ This is the central parsing function. It can both append new text and
+ extract objects from the stream accumulated so far (both of these
+ functions are optional).
+
+ If $string is given, then this string is appended to the already
+ existing JSON fragment stored in the $json object.
+
+ After that, if the function is called in void context, it will simply
+ return without doing anything further. This can be used to add more text
+ in as many chunks as you want.
+
+ If the method is called in scalar context, then it will try to extract
+ exactly *one* JSON object. If that is successful, it will return this
+ object, otherwise it will return "undef". If there is a parse error,
+ this method will croak just as "decode" would do (one can then use
+ "incr_skip" to skip the erroneous part). This is the most common way of
+ using the method.
+
+ And finally, in list context, it will try to extract as many objects
+ from the stream as it can find and return them, or the empty list
+ otherwise. For this to work, there must be no separators between the
+ JSON objects or arrays, instead they must be concatenated back-to-back.
+ If an error occurs, an exception will be raised as in the scalar context
+ case. Note that in this case, any previously-parsed JSON texts will be
+ lost.
+
+ Example: Parse some JSON arrays/objects in a given string and return
+ them.
+
+ my @objs = JSON->new->incr_parse ("[5][7][1,2]");
+
+ incr_text
+ $lvalue_string = $json->incr_text
+
+ This method returns the currently stored JSON fragment as an lvalue,
+ that is, you can manipulate it. This *only* works when a preceding call
+ to "incr_parse" in *scalar context* successfully returned an object.
+ Under all other circumstances you must not call this function (I mean
+ it. although in simple tests it might actually work, it *will* fail
+ under real world conditions). As a special exception, you can also call
+ this method before having parsed anything.
+
+ This function is useful in two cases: a) finding the trailing text after
+ a JSON object or b) parsing multiple JSON objects separated by non-JSON
+ text (such as commas).
+
+ $json->incr_text =~ s/\s*,\s*//;
+
+ In Perl 5.005, "lvalue" attribute is not available. You must write codes
+ like the below:
+
+ $string = $json->incr_text;
+ $string =~ s/\s*,\s*//;
+ $json->incr_text( $string );
+
+ incr_skip
+ $json->incr_skip
+
+ This will reset the state of the incremental parser and will remove the
+ parsed text from the input buffer. This is useful after "incr_parse"
+ died, in which case the input buffer and incremental parser state is
+ left unchanged, to skip the text parsed so far and to reset the parse
+ state.
+
+ incr_reset
+ $json->incr_reset
+
+ This completely resets the incremental parser, that is, after this call,
+ it will be as if the parser had never parsed anything.
+
+ This is useful if you want to repeatedly parse JSON objects and want to
+ ignore any trailing data, which means you have to reset the parser after
+ each successful decode.
+
+ See to "INCREMENTAL PARSING" in JSON::XS for examples.
+
+JSON::PP SUPPORT METHODS
+ The below methods are JSON::PP own methods, so when "JSON" works with
+ JSON::PP (i.e. the created object is a JSON::PP object), available. See
+ to "JSON::PP OWN METHODS" in JSON::PP in detail.
+
+ If you use "JSON" with additional "-support_by_pp", some methods are
+ available even with JSON::XS. See to "USE PP FEATURES EVEN THOUGH XS
+ BACKEND".
+
+ BEING { $ENV{PERL_JSON_BACKEND} = 'JSON::XS' }
+
+ use JSON -support_by_pp;
+
+ my $json = JSON->new;
+ $json->allow_nonref->escape_slash->encode("/");
+
+ # functional interfaces too.
+ print to_json(["/"], {escape_slash => 1});
+ print from_json('["foo"]', {utf8 => 1});
+
+ If you do not want to all functions but "-support_by_pp", use
+ "-no_export".
+
+ use JSON -support_by_pp, -no_export;
+ # functional interfaces are not exported.
+
+ allow_singlequote
+ $json = $json->allow_singlequote([$enable])
+
+ If $enable is true (or missing), then "decode" will accept any JSON
+ strings quoted by single quotations that are invalid JSON format.

+ $json->allow_singlequote->decode({'foo':'bar'});
+
+ As same as the "relaxed" option, this option may be used to parse
+ application-specific files written by humans.
+
+ allow_barekey
+ $json = $json->allow_barekey([$enable])
+
+ If $enable is true (or missing), then "decode" will accept bare keys of
+ JSON object that are invalid JSON format.
+
+ As same as the "relaxed" option, this option may be used to parse
+ application-specific files written by humans.
+
+ $json->allow_barekey->decode('{foo:"bar"}');
+
+ allow_bignum
+ $json = $json->allow_bignum([$enable])
+
+ If $enable is true (or missing), then "decode" will convert the big
+ integer Perl cannot handle as integer into a Math::BigInt object and
+ convert a floating number (any) into a Math::BigFloat.
+
+ On the contrary, "encode" converts "Math::BigInt" objects and
+ "Math::BigFloat" objects into JSON numbers with "allow_blessed" enable.
+
+ $json->allow_nonref->allow_blessed->allow_bignum;
+ $bigfloat = $json->decode('2.000000000000000000000000001');
+ print $json->encode($bigfloat);
+ # => 2.000000000000000000000000001
+
+ See to MAPPING about the conversion of JSON number.
+
+ loose
+ $json = $json->loose([$enable])
+
+ The unescaped [\x00-\x1f\x22\x2f\x5c] strings are invalid in JSON
+ strings and the module doesn't allow to "decode" to these (except for
+ \x2f). If $enable is true (or missing), then "decode" will accept these
+ unescaped strings.
+
+ $json->loose->decode(qq|["abc
+ def"]|);
+
+ See to "JSON::PP OWN METHODS" in JSON::PP.
+
+ escape_slash
+ $json = $json->escape_slash([$enable])
+
+ According to JSON Grammar, *slash* (U+002F) is escaped. But by default
+ JSON backend modules encode strings without escaping slash.
+
+ If $enable is true (or missing), then "encode" will escape slashes.
+
+ indent_length
+ $json = $json->indent_length($length)
+
+ With JSON::XS, The indent space length is 3 and cannot be changed. With
+ JSON::PP, it sets the indent space length with the given $length. The
+ default is 3. The acceptable range is 0 to 15.
+
+ sort_by
+ $json = $json->sort_by($function_name)
+ $json = $json->sort_by($subroutine_ref)
+
+ If $function_name or $subroutine_ref are set, its sort routine are used.
+
+ $js = $pc->sort_by(sub { $JSON::PP::a cmp $JSON::PP::b })->encode($obj);
+ # is($js, q|{"a":1,"b":2,"c":3,"d":4,"e":5,"f":6,"g":7,"h":8,"i":9}|);
+
+ $js = $pc->sort_by('own_sort')->encode($obj);
+ # is($js, q|{"a":1,"b":2,"c":3,"d":4,"e":5,"f":6,"g":7,"h":8,"i":9}|);
+
+ sub JSON::PP::own_sort { $JSON::PP::a cmp $JSON::PP::b }
+
+ As the sorting routine runs in the JSON::PP scope, the given subroutine
+ name and the special variables $a, $b will begin with 'JSON::PP::'.
+
+ If $integer is set, then the effect is same as "canonical" on.
+
+ See to "JSON::PP OWN METHODS" in JSON::PP.
+
+MAPPING
+ This section is copied from JSON::XS and modified to "JSON". JSON::XS
+ and JSON::PP mapping mechanisms are almost equivalent.
+
+ See to "MAPPING" in JSON::XS.
+
+ JSON -> PERL
+ object
+ A JSON object becomes a reference to a hash in Perl. No ordering of
+ object keys is preserved (JSON does not preserver object key
+ ordering itself).
+
+ array
+ A JSON array becomes a reference to an array in Perl.
+
+ string
+ A JSON string becomes a string scalar in Perl - Unicode codepoints
+ in JSON are represented by the same codepoints in the Perl string,
+ so no manual decoding is necessary.
+
+ number
+ A JSON number becomes either an integer, numeric (floating point) or
+ string scalar in perl, depending on its range and any fractional
+ parts. On the Perl level, there is no difference between those as
+ Perl handles all the conversion details, but an integer may take
+ slightly less memory and might represent more values exactly than
+ floating point numbers.
+
+ If the number consists of digits only, "JSON" will try to represent
+ it as an integer value. If that fails, it will try to represent it
+ as a numeric (floating point) value if that is possible without loss
+ of precision. Otherwise it will preserve the number as a string
+ value (in which case you lose roundtripping ability, as the JSON
+ number will be re-encoded to a JSON string).
+
+ Numbers containing a fractional or exponential part will always be
+ represented as numeric (floating point) values, possibly at a loss
+ of precision (in which case you might lose perfect roundtripping
+ ability, but the JSON number will still be re-encoded as a JSON
+ number).
+
+ Note that precision is not accuracy - binary floating point values
+ cannot represent most decimal fractions exactly, and when converting
+ from and to floating point, "JSON" only guarantees precision up to
+ but not including the least significant bit.
+
+ If the backend is JSON::PP and "allow_bignum" is enable, the big
+ integers and the numeric can be optionally converted into
+ Math::BigInt and Math::BigFloat objects.
+
+ true, false
+ These JSON atoms become "JSON::true" and "JSON::false",
+ respectively. They are overloaded to act almost exactly like the
+ numbers 1 and 0. You can check whether a scalar is a JSON boolean by
+ using the "JSON::is_bool" function.
+
+ print JSON::true + 1;
+ => 1
+
+ ok(JSON::true eq '1');
+ ok(JSON::true == 1);
+
+ "JSON" will install these missing overloading features to the
+ backend modules.
+
+ null
+ A JSON null atom becomes "undef" in Perl.
+
+ "JSON::null" returns "undef".
+
+ PERL -> JSON
+ The mapping from Perl to JSON is slightly more difficult, as Perl is a
+ truly typeless language, so we can only guess which JSON type is meant
+ by a Perl value.
+
+ hash references
+ Perl hash references become JSON objects. As there is no inherent
+ ordering in hash keys (or JSON objects), they will usually be
+ encoded in a pseudo-random order that can change between runs of the
+ same program but stays generally the same within a single run of a
+ program. "JSON" optionally sort the hash keys (determined by the
+ *canonical* flag), so the same data structure will serialise to the
+ same JSON text (given same settings and version of JSON::XS), but
+ this incurs a runtime overhead and is only rarely useful, e.g. when
+ you want to compare some JSON text against another for equality.
+
+ In future, the ordered object feature will be added to JSON::PP
+ using "tie" mechanism.
+
+ array references
+ Perl array references become JSON arrays.
+
+ other references
+ Other unblessed references are generally not allowed and will cause
+ an exception to be thrown, except for references to the integers 0
+ and 1, which get turned into "false" and "true" atoms in JSON. You
+ can also use "JSON::false" and "JSON::true" to improve readability.
+
+ to_json [\0,JSON::true] # yields [false,true]
+
+ JSON::true, JSON::false, JSON::null
+ These special values become JSON true and JSON false values,
+ respectively. You can also use "\1" and "\0" directly if you want.
+
+ JSON::null returns "undef".
+
+ blessed objects
+ Blessed objects are not directly representable in JSON. See the
+ "allow_blessed" and "convert_blessed" methods on various options on
+ how to deal with this: basically, you can choose between throwing an
+ exception, encoding the reference as if it weren't blessed, or
+ provide your own serialiser method.
+
+ With "convert_blessed_universally" mode, "encode" converts blessed
+ hash references or blessed array references (contains other blessed
+ references) into JSON members and arrays.
+
+ use JSON -convert_blessed_universally;
+ JSON->new->allow_blessed->convert_blessed->encode( $blessed_object );
+
+ See to convert_blessed.
+
+ simple scalars
+ Simple Perl scalars (any scalar that is not a reference) are the
+ most difficult objects to encode: JSON::XS and JSON::PP will encode
+ undefined scalars as JSON "null" values, scalars that have last been
+ used in a string context before encoding as JSON strings, and
+ anything else as number value:
+
+ # dump as number
+ encode_json [2] # yields [2]
+ encode_json [-3.0e17] # yields [-3e+17]
+ my $value = 5; encode_json [$value] # yields [5]
+
+ # used as string, so dump as string
+ print $value;
+ encode_json [$value] # yields ["5"]
+
+ # undef becomes null
+ encode_json [undef] # yields [null]
+
+ You can force the type to be a string by stringifying it:
+
+ my $x = 3.1; # some variable containing a number
+ "$x"; # stringified
+ $x .= ""; # another, more awkward way to stringify
+ print $x; # perl does it for you, too, quite often
+
+ You can force the type to be a number by numifying it:
+
+ my $x = "3"; # some variable containing a string
+ $x += 0; # numify it, ensuring it will be dumped as a number
+ $x *= 1; # same thing, the choice is yours.
+
+ You can not currently force the type in other, less obscure, ways.
+
+ Note that numerical precision has the same meaning as under Perl (so
+ binary to decimal conversion follows the same rules as in Perl,
+ which can differ to other languages). Also, your perl interpreter
+ might expose extensions to the floating point numbers of your
+ platform, such as infinities or NaN's - these cannot be represented
+ in JSON, and it is an error to pass those in.
+
+ Big Number
+ If the backend is JSON::PP and "allow_bignum" is enable, "encode"
+ converts "Math::BigInt" objects and "Math::BigFloat" objects into
+ JSON numbers.
+
+JSON and ECMAscript
+ See to "JSON and ECMAscript" in JSON::XS.
+
+JSON and YAML
+ JSON is not a subset of YAML. See to "JSON and YAML" in JSON::XS.
+
+BACKEND MODULE DECISION
+ When you use "JSON", "JSON" tries to "use" JSON::XS. If this call
+ failed, it will "uses" JSON::PP. The required JSON::XS version is *2.2*
+ or later.
+
+ The "JSON" constructor method returns an object inherited from the
+ backend module, and JSON::XS object is a blessed scalar reference while
+ JSON::PP is a blessed hash reference.
+
+ So, your program should not depend on the backend module, especially
+ returned objects should not be modified.
+
+ my $json = JSON->new; # XS or PP?
+ $json->{stash} = 'this is xs object'; # this code may raise an error!
+
+ To check the backend module, there are some methods - "backend", "is_pp"
+ and "is_xs".
+
+ JSON->backend; # 'JSON::XS' or 'JSON::PP'
+
+ JSON->backend->is_pp: # 0 or 1
+
+ JSON->backend->is_xs: # 1 or 0
+
+ $json->is_xs; # 1 or 0
+
+ $json->is_pp; # 0 or 1
+
+ If you set an environment variable "PERL_JSON_BACKEND", the calling
+ action will be changed.
+
+ PERL_JSON_BACKEND = 0 or PERL_JSON_BACKEND = 'JSON::PP'
+ Always use JSON::PP
+
+ PERL_JSON_BACKEND == 1 or PERL_JSON_BACKEND = 'JSON::XS,JSON::PP'
+ (The default) Use compiled JSON::XS if it is properly compiled &
+ installed, otherwise use JSON::PP.
+
+ PERL_JSON_BACKEND == 2 or PERL_JSON_BACKEND = 'JSON::XS'
+ Always use compiled JSON::XS, die if it isn't properly compiled &
+ installed.
+
+ PERL_JSON_BACKEND = 'JSON::backportPP'
+ Always use JSON::backportPP. JSON::backportPP is JSON::PP back port
+ module. "JSON" includes JSON::backportPP instead of JSON::PP.
+
+ These ideas come from DBI::PurePerl mechanism.
+
+ example:
+
+ BEGIN { $ENV{PERL_JSON_BACKEND} = 'JSON::PP' }
+ use JSON; # always uses JSON::PP
+
+ In future, it may be able to specify another module.
+
+USE PP FEATURES EVEN THOUGH XS BACKEND
+ Many methods are available with either JSON::XS or JSON::PP and when the
+ backend module is JSON::XS, if any JSON::PP specific (i.e. JSON::XS
+ unsupported) method is called, it will "warn" and be noop.
+
+ But If you "use" "JSON" passing the optional string "-support_by_pp", it
+ makes a part of those unsupported methods available. This feature is
+ achieved by using JSON::PP in "de/encode".
+
+ BEGIN { $ENV{PERL_JSON_BACKEND} = 2 } # with JSON::XS
+ use JSON -support_by_pp;
+ my $json = JSON->new;
+ $json->allow_nonref->escape_slash->encode("/");
+
+ At this time, the returned object is a "JSON::Backend::XS::Supportable"
+ object (re-blessed XS object), and by checking JSON::XS unsupported
+ flags in de/encoding, can support some unsupported methods - "loose",
+ "allow_bignum", "allow_barekey", "allow_singlequote", "escape_slash" and
+ "indent_length".
+
+ When any unsupported methods are not enable, "XS de/encode" will be used
+ as is. The switch is achieved by changing the symbolic tables.
+
+ "-support_by_pp" is effective only when the backend module is JSON::XS
+ and it makes the de/encoding speed down a bit.
+
+ See to "JSON::PP SUPPORT METHODS".
+
+INCOMPATIBLE CHANGES TO OLD VERSION
+ There are big incompatibility between new version (2.00) and old (1.xx).
+ If you use old "JSON" 1.xx in your code, please check it.
+
+ See to "Transition ways from 1.xx to 2.xx."
+
+ jsonToObj and objToJson are obsoleted.
+ Non Perl-style name "jsonToObj" and "objToJson" are obsoleted (but
+ not yet deleted from the source). If you use these functions in your
+ code, please replace them with "from_json" and "to_json".
+
+ Global variables are no longer available.
+ "JSON" class variables - $JSON::AUTOCONVERT, $JSON::BareKey, etc...
+ - are not available any longer. Instead, various features can be
+ used through object methods.
+
+ Package JSON::Converter and JSON::Parser are deleted.
+ Now "JSON" bundles with JSON::PP which can handle JSON more properly
+ than them.
+
+ Package JSON::NotString is deleted.
+ There was "JSON::NotString" class which represents JSON value
+ "true", "false", "null" and numbers. It was deleted and replaced by
+ "JSON::Boolean".
+
+ "JSON::Boolean" represents "true" and "false".
+
+ "JSON::Boolean" does not represent "null".
+
+ "JSON::null" returns "undef".
+
+ "JSON" makes JSON::XS::Boolean and JSON::PP::Boolean is-a relation
+ to JSON::Boolean.
+
+ function JSON::Number is obsoleted.
+ "JSON::Number" is now needless because JSON::XS and JSON::PP have
+ round-trip integrity.
+
+ JSONRPC modules are deleted.
+ Perl implementation of JSON-RPC protocol - "JSONRPC ",
+ "JSONRPC::Transport::HTTP" and "Apache::JSONRPC " are deleted in
+ this distribution. Instead of them, there is JSON::RPC which
+ supports JSON-RPC protocol version 1.1.
+
+ Transition ways from 1.xx to 2.xx.
+ You should set "suport_by_pp" mode firstly, because it is always
+ successful for the below codes even with JSON::XS.
+
+ use JSON -support_by_pp;
+
+ Exported jsonToObj (simple)
+ from_json($json_text);
+
+ Exported objToJson (simple)
+ to_json($perl_scalar);
+
+ Exported jsonToObj (advanced)
+ $flags = {allow_barekey => 1, allow_singlequote => 1};
+ from_json($json_text, $flags);
+
+ equivalent to:
+
+ $JSON::BareKey = 1;
+ $JSON::QuotApos = 1;
+ jsonToObj($json_text);
+
+ Exported objToJson (advanced)
+ $flags = {allow_blessed => 1, allow_barekey => 1};
+ to_json($perl_scalar, $flags);
+
+ equivalent to:
+
+ $JSON::BareKey = 1;
+ objToJson($perl_scalar);
+
+ jsonToObj as object method
+ $json->decode($json_text);
+
+ objToJson as object method
+ $json->encode($perl_scalar);
+
+ new method with parameters
+ The "new" method in 2.x takes any parameters no longer. You can set
+ parameters instead;
+
+ $json = JSON->new->pretty;
+
+ $JSON::Pretty, $JSON::Indent, $JSON::Delimiter
+ If "indent" is enable, that means $JSON::Pretty flag set. And
+ $JSON::Delimiter was substituted by "space_before" and
+ "space_after". In conclusion:
+
+ $json->indent->space_before->space_after;
+
+ Equivalent to:
+
+ $json->pretty;
+
+ To change indent length, use "indent_length".
+
+ (Only with JSON::PP, if "-support_by_pp" is not used.)
+
+ $json->pretty->indent_length(2)->encode($perl_scalar);
+
+ $JSON::BareKey
+ (Only with JSON::PP, if "-support_by_pp" is not used.)
+
+ $json->allow_barekey->decode($json_text)
+
+ $JSON::ConvBlessed
+ use "-convert_blessed_universally". See to convert_blessed.
+
+ $JSON::QuotApos
+ (Only with JSON::PP, if "-support_by_pp" is not used.)
+
+ $json->allow_singlequote->decode($json_text)
+
+ $JSON::SingleQuote
+ Disable. "JSON" does not make such a invalid JSON string any longer.
+
+ $JSON::KeySort
+ $json->canonical->encode($perl_scalar)
+
+ This is the ascii sort.
+
+ If you want to use with your own sort routine, check the "sort_by"
+ method.
+
+ (Only with JSON::PP, even if "-support_by_pp" is used currently.)
+
+ $json->sort_by($sort_routine_ref)->encode($perl_scalar)
+
+ $json->sort_by(sub { $JSON::PP::a <=> $JSON::PP::b })->encode($perl_scalar)
+
+ Can't access $a and $b but $JSON::PP::a and $JSON::PP::b.
+
+ $JSON::SkipInvalid
+ $json->allow_unknown
+
+ $JSON::AUTOCONVERT
+ Needless. "JSON" backend modules have the round-trip integrity.
+
+ $JSON::UTF8
+ Needless because "JSON" (JSON::XS/JSON::PP) sets the UTF8 flag on
+ properly.
+
+ # With UTF8-flagged strings
+
+ $json->allow_nonref;
+ $str = chr(1000); # UTF8-flagged
+
+ $json_text = $json->utf8(0)->encode($str);
+ utf8::is_utf8($json_text);
+ # true
+ $json_text = $json->utf8(1)->encode($str);
+ utf8::is_utf8($json_text);
+ # false
+
+ $str = '"' . chr(1000) . '"'; # UTF8-flagged
+
+ $perl_scalar = $json->utf8(0)->decode($str);
+ utf8::is_utf8($perl_scalar);
+ # true
+ $perl_scalar = $json->utf8(1)->decode($str);
+ # died because of 'Wide character in subroutine'
+
+ See to "A FEW NOTES ON UNICODE AND PERL" in JSON::XS.
+
+ $JSON::UnMapping
+ Disable. See to MAPPING.
+
+ $JSON::SelfConvert
+ This option was deleted. Instead of it, if a given blessed object
+ has the "TO_JSON" method, "TO_JSON" will be executed with
+ "convert_blessed".
+
+ $json->convert_blessed->encode($blessed_hashref_or_arrayref)
+ # if need, call allow_blessed
+
+ Note that it was "toJson" in old version, but now not "toJson" but
+ "TO_JSON".

-=head1 NAME
-
-JSON::PP - An experimental JSON::XS compatible Pure Perl module.
-
-=head1 SYNOPSIS
-
- use JSON::PP;
-
- $obj = from_json($json_text);
- $json_text = to_json($obj);
-
- # or
-
- $obj = jsonToObj($json_text);
- $json_text = objToJson($obj);
-
- $json = new JSON;
- $json_text = $json->ascii->pretty($obj);
-
- # you can set options to functions.
-
- $json_text = to_json($obj, {ascii => 1, intend => 2});
- $obj = from_json($json_text, {utf8 => 0});
-
-
-=head1 DESCRIPTION
-
-This module is L<JSON::XS> compatible Pure Perl module.
-( Perl better than 5.008 is recommended)
-
-Module variables ($JSON::*) were abolished.
-
-JSON::PP will be renamed JSON (JSON-2.0).
-
-Many things including error handling are learned from L<JSON::XS>.
-For t/02_error.t compatible, error messages was copied partially from JSON::XS.
-
-
-=head2 FEATURES
-
-=over
-
-=item * perhaps correct unicode handling
-
-This module knows how to handle Unicode (perhaps),
-but not yet documents how and when it does so.
-
-In Perl5.6x, Unicode handling requires L<Unicode::String> module.
-
-Perl 5.005_xx, Unicode handling is disable currenlty.
-
-
-=item * round-trip integrity
-
-This module solved the problem pointed out by JSON::XS
-using L<B> module.
-
-=item * strict checking of JSON correctness
-
-I want to bring close to XS.
-How do you want to carry out?
-
-you can set C<strict> decoding method.
-
-=item * slow
-
-Compared to other JSON modules, this module does not compare
-favourably in terms of speed. Very slowly!
-
-=item * simple to use
-
-This module became very simple.
-Since its interface were anyway made the same as JSON::XS.
-
-
-=item * reasonably versatile output formats
-
-See to L<JSON::XS>.

-
-=item to_json
-
-See to JSON::XS.
-C<objToJson> is an alias.
-

-
-See to JSON::XS.
-C<jsonToObj> is an alias.
-
-
-=item JSON::PP::true
-
-Returns JSON true value which is blessed object.
-It C<isa> JSON::PP::Boolean object.
-
-=item JSON::PP::false
-
-Returns JSON false value which is blessed object.
-It C<isa> JSON::PP::Boolean object.
-
-
-=item JSON::PP::null
-
-Returns C<undef>.

-
-=item new
-
-Returns JSON::PP object.
-
-=item ascii
-
-See to JSON::XS.
-
-In Perl 5.6, this method requires L<Unicode::String>.
-If you don't have Unicode::String,
-the method is always set to false and warns.
-
-In Perl 5.005, this option is currently disable.
-

-In Perl 5.6, this method requires L<Unicode::String>.
-If you don't have Unicode::String,
-the method is always set to false and warns.
-
-In Perl 5.005, this option is currently disable.
-
-
-=item utf8
-
-See to JSON::XS.
-
-Currently this module always handles UTF-16 as UTF-16BE.
-
-=item pretty
-
-See to JSON::XS.
-
-=item indent
-
-See to JSON::XS.
-Strictly, this module does not carry out equivalent to XS.
-
- $json->indent(4);
-
-is not the same as this:
-
- $json->indent();
-
-
-=item space_before
-
-See to JSON::XS.
-
-=item space_after
-
-See JSON::XS.
-
-=item canonical
-
-See to JSON::XS.
-Strictly, this module does not carry out equivalent to XS.
-This method can take a subref for sorting (see to L<JSON>).
-
-
-=item allow_nonref
-
-See to JSON::XS.
-
-=item shrink
-
-Not yet implemented.
-
-=item max_depth
-
-See to JSON::XS.
-Strictly, this module does not carry out equivalent to XS.
-By default, 512.
-
-When a large value is set, it may raise a warning 'Deep recursion on subroutin'.
-
-
-=item max_size
-
-
-=item relaxed
-
-
-=item allow_blessed
-
-
-=item convert_blessed
-
-
-=item filter_json_object
-
-
-=item filter_json_single_key_object
-
-
-
-=item encode
-
-See to JSON::XS.
-
-=item decode
-
-See to JSON::XS.
-In Perl 5.6, if you don't have Unicode::String,
-the method can't handle UTF-16(BE) char and returns as is.
-
-
-=item property
-
-Accessor.
-
- $json->property(utf8 => 1); # $json->utf8(1);
-
- $value = $json->property('utf8'); # returns 1.
-
-
-=item self_encode
-
-See L<JSON/BLESSED OBJECT>'s I<self convert> function.
-
-Will be obsoleted.
-
-
-=item disable_UTF8
-
-If this option is set, UTF8 flag in strings generated
-by C<encode>/C<decode> is off.
-
-
-=item allow_tied
-
-Now disable.
-
-
-=item singlequote
-
-Allows to decode single quoted strings.
-
-Unlike L<JSON> module, this module does not encode
-Perl string into single quoted string any longer.
-
-
-=item allow_barekey
-
-Allows to decode bare key of member.
-
-
-=item allow_bigint
-
-When json text has any integer in decoding more than Perl can't handle,
-If this option is on, they are converted into L<Math::BigInt> objects.
-
-
-=item strict
-
-For JSON format, unescaped [\x00-\x1f\x22\x2f\x5c] strings are invalid and
-JSON::XS decodes just like that (except for \x2f). While this module can deocde thoese.
-But if this option is set, the module strictly decodes.
-
-This option will be obsoleted and 'un-strict' will be added insted.
-
-=item escape_slash
-
-By default, JSON::PP encodes strings without escaping slash (U+002F).
-Setting the option to escape slash.
-
-
-
-
-=back
-
-
-=head1 MAPPING
-
-Now same as JSON::XS.
-
-
-=head1 COMPARISON
-
-Using a benchmark program in the JSON::XS (v1.11) distribution.
-
- module | encode | decode |
- -----------|------------|------------|
- JSON::PP | 11092.260 | 4482.033 |
- -----------+------------+------------+
- JSON::XS | 341513.380 | 226138.509 |
- -----------+------------+------------+
-
-In case t/12_binary.t (JSON::XS distribution).
-(shrink of JSON::PP has no effect.)
-
-JSON::PP takes 147 (sec).
-
-JSON::XS takes 4.

+=head1 VERSION
+
+ 2.27200
+
+L<JSON::XS> 2.27 (~2.30) compatible.
+
+=head1 DESCRIPTION
+
+This module is L<JSON::XS> compatible pure Perl module.
+(Perl 5.8 or later is recommended)
+
+JSON::XS is the fastest and most proper JSON module on CPAN.
+It is written by Marc Lehmann in C, so must be compiled and
+installed in the used environment.
+
+JSON::PP is a pure-Perl module and has compatibility to JSON::XS.
+
+
+=head2 FEATURES
+
+=over
+
+=item * correct unicode handling
+
+This module knows how to handle Unicode (depending on Perl version).
+
+See to L<JSON::XS/A FEW NOTES ON UNICODE AND PERL> and
+L<UNICODE HANDLING ON PERLS>.
+
+
+=item * round-trip integrity
+
+When you serialise a perl data structure using only data types
+supported by JSON and Perl, the deserialised data structure is
+identical on the Perl level. (e.g. the string "2.0" doesn't suddenly
+become "2" just because it looks like a number). There I<are> minor
+exceptions to this, read the MAPPING section below to learn about
+those.
+
+
+=item * strict checking of JSON correctness
+
+There is no guessing, no generating of illegal JSON texts by default,
+and only JSON is accepted as input by default (the latter is a
+security feature). But when some options are set, loose checking
+features are available.
+
+=back
+
+=head1 FUNCTIONAL INTERFACE
+
+Some documents are copied and modified from L<JSON::XS/FUNCTIONAL INTERFACE>.
+
+=head2 encode_json
+
+ $json_text = encode_json $perl_scalar
+
+Converts the given Perl data structure to a UTF-8 encoded, binary string.
+
+This function call is functionally identical to:
+
+ $json_text = JSON::PP->new->utf8->encode($perl_scalar)
+
+=head2 decode_json
+
+ $perl_scalar = decode_json $json_text
+
+The opposite of C<encode_json>: expects an UTF-8 (binary) string and tries
+to parse that as an UTF-8 encoded JSON text, returning the resulting
+reference.
+
+This function call is functionally identical to:
+
+ $perl_scalar = JSON::PP->new->utf8->decode($json_text)
+
+=head2 JSON::PP::is_bool
+
+ $is_boolean = JSON::PP::is_bool($scalar)
+
+Returns true if the passed scalar represents either JSON::PP::true or
+JSON::PP::false, two constants that act like C<1> and C<0> respectively
+and are also used to represent JSON C<true> and C<false> in Perl strings.
+
+=head2 JSON::PP::true
+
+Returns JSON true value which is blessed object.
+It C<isa> JSON::PP::Boolean object.
+
+=head2 JSON::PP::false
+
+Returns JSON false value which is blessed object.
+It C<isa> JSON::PP::Boolean object.
+
+=head2 JSON::PP::null
+
+Returns C<undef>.
+
+See L<MAPPING>, below, for more information on how JSON values are mapped to
+Perl.
+
+
+=head1 HOW DO I DECODE A DATA FROM OUTER AND ENCODE TO OUTER
+
+This section supposes that your perl version is 5.8 or later.
+
+If you know a JSON text from an outer world - a network, a file content, and so on,
+is encoded in UTF-8, you should use C<decode_json> or C<JSON> module object
+with C<utf8> enable. And the decoded result will contain UNICODE characters.
+
+ # from network
+ my $json = JSON::PP->new->utf8;
+ my $json_text = CGI->new->param( 'json_data' );
+ my $perl_scalar = $json->decode( $json_text );
+
+ # from file content
+ local $/;
+ open( my $fh, '<', 'json.data' );
+ $json_text = <$fh>;
+ $perl_scalar = decode_json( $json_text );
+
+If an outer data is not encoded in UTF-8, firstly you should C<decode> it.
+
+ use Encode;
+ local $/;
+ open( my $fh, '<', 'json.data' );
+ my $encoding = 'cp932';
+ my $unicode_json_text = decode( $encoding, <$fh> ); # UNICODE
+
+ # or you can write the below code.
+ #
+ # open( my $fh, "<:encoding($encoding)", 'json.data' );
+ # $unicode_json_text = <$fh>;
+
+In this case, C<$unicode_json_text> is of course UNICODE string.
+So you B<cannot> use C<decode_json> nor C<JSON> module object with C<utf8> enable.
+Instead of them, you use C<JSON> module object with C<utf8> disable.
+
+ $perl_scalar = $json->utf8(0)->decode( $unicode_json_text );
+
+Or C<encode 'utf8'> and C<decode_json>:
+
+ $perl_scalar = decode_json( encode( 'utf8', $unicode_json_text ) );
+ # this way is not efficient.
+
+And now, you want to convert your C<$perl_scalar> into JSON data and
+send it to an outer world - a network or a file content, and so on.
+
+Your data usually contains UNICODE strings and you want the converted data to be encoded
+in UTF-8, you should use C<encode_json> or C<JSON> module object with C<utf8> enable.
+
+ print encode_json( $perl_scalar ); # to a network? file? or display?
+ # or
+ print $json->utf8->encode( $perl_scalar );
+
+If C<$perl_scalar> does not contain UNICODE but C<$encoding>-encoded strings
+for some reason, then its characters are regarded as B<latin1> for perl
+(because it does not concern with your $encoding).
+You B<cannot> use C<encode_json> nor C<JSON> module object with C<utf8> enable.
+Instead of them, you use C<JSON> module object with C<utf8> disable.
+Note that the resulted text is a UNICODE string but no problem to print it.
+
+ # $perl_scalar contains $encoding encoded string values
+ $unicode_json_text = $json->utf8(0)->encode( $perl_scalar );
+ # $unicode_json_text consists of characters less than 0x100
+ print $unicode_json_text;
+
+Or C<decode $encoding> all string values and C<encode_json>:
+
+ $perl_scalar->{ foo } = decode( $encoding, $perl_scalar->{ foo } );
+ # ... do it to each string values, then encode_json
+ $json_text = encode_json( $perl_scalar );
+
+This method is a proper way but probably not efficient.
+
+See to L<Encode>, L<perluniintro>.
+
+
+=head1 METHODS
+
+Basically, check to L<JSON> or L<JSON::XS>.
+
+=head2 new
+
+ $json = JSON::PP->new
+
+Returns a new JSON::PP object that can be used to de/encode JSON
+strings.
+
+All boolean flags described below are by default I<disabled>.
+
+The mutators for flags all return the JSON object again and thus calls can
+be chained:
+
+ my $json = JSON::PP->new->utf8->space_after->encode({a => [1,2]})
+ => {"a": [1, 2]}
+
+=head2 ascii
+
+ $json = $json->ascii([$enable])
+
+ $enabled = $json->get_ascii
+
+If $enable is true (or missing), then the encode method will not generate characters outside
+the code range 0..127. Any Unicode characters outside that range will be escaped using either
+a single \uXXXX or a double \uHHHH\uLLLLL escape sequence, as per RFC4627.
+(See to L<JSON::XS/OBJECT-ORIENTED INTERFACE>).
+
+In Perl 5.005, there is no character having high value (more than 255).
+See to L<UNICODE HANDLING ON PERLS>.
+
+If $enable is false, then the encode method will not escape Unicode characters unless
+required by the JSON syntax or other flags. This results in a faster and more compact format.
+
+ JSON::PP->new->ascii(1)->encode([chr 0x10401])
+ => ["\ud801\udc01"]
+
+=head2 latin1
+
+ $json = $json->latin1([$enable])
+
+ $enabled = $json->get_latin1
+
+If $enable is true (or missing), then the encode method will encode the resulting JSON
+text as latin1 (or iso-8859-1), escaping any characters outside the code range 0..255.
+
+If $enable is false, then the encode method will not escape Unicode characters
+unless required by the JSON syntax or other flags.
+
+ JSON::XS->new->latin1->encode (["\x{89}\x{abc}"]
+ => ["\x{89}\\u0abc"] # (perl syntax, U+abc escaped, U+89 not)
+
+See to L<UNICODE HANDLING ON PERLS>.
+
+=head2 utf8
+
+ $json = $json->utf8([$enable])
+
+ $enabled = $json->get_utf8
+
+If $enable is true (or missing), then the encode method will encode the JSON result
+into UTF-8, as required by many protocols, while the decode method expects to be handled
+an UTF-8-encoded string. Please note that UTF-8-encoded strings do not contain any
+characters outside the range 0..255, they are thus useful for bytewise/binary I/O.
+
+(In Perl 5.005, any character outside the range 0..255 does not exist.
+See to L<UNICODE HANDLING ON PERLS>.)
+
+In future versions, enabling this option might enable autodetection of the UTF-16 and UTF-32
+encoding families, as described in RFC4627.
+
+If $enable is false, then the encode method will return the JSON string as a (non-encoded)
+Unicode string, while decode expects thus a Unicode string. Any decoding or encoding
+(e.g. to UTF-8 or UTF-16) needs to be done yourself, e.g. using the Encode module.
+
+Example, output UTF-16BE-encoded JSON:
+
+ use Encode;
+ $jsontext = encode "UTF-16BE", JSON::PP->new->encode ($object);
+
+Example, decode UTF-32LE-encoded JSON:
+
+ use Encode;
+ $object = JSON::PP->new->decode (decode "UTF-32LE", $jsontext);
+
+
+=head2 pretty
+
+ $json = $json->pretty([$enable])
+
+This enables (or disables) all of the C<indent>, C<space_before> and
+C<space_after> flags in one call to generate the most readable
+(or most compact) form possible.
+
+Equivalent to:
+
+ $json->indent->space_before->space_after
+
+=head2 indent
+
+ $json = $json->indent([$enable])
+
+ $enabled = $json->get_indent
+
+The default indent space length is three.
+You can use C<indent_length> to change the length.
+
+=head2 space_before
+
+ $json = $json->space_before([$enable])
+
+ $enabled = $json->get_space_before
+
+If C<$enable> is true (or missing), then the C<encode> method will add an extra
+optional space before the C<:> separating keys from values in JSON objects.
+
+If C<$enable> is false, then the C<encode> method will not add any extra
+space at those places.
+
+This setting has no effect when decoding JSON texts.
+
+Example, space_before enabled, space_after and indent disabled:
+
+ {"key" :"value"}
+
+=head2 space_after
+
+ $json = $json->space_after([$enable])
+
+ $enabled = $json->get_space_after
+
+If C<$enable> is true (or missing), then the C<encode> method will add an extra
+optional space after the C<:> separating keys from values in JSON objects
+and extra whitespace after the C<,> separating key-value pairs and array
+members.
+
+If C<$enable> is false, then the C<encode> method will not add any extra
+space at those places.
+
+This setting has no effect when decoding JSON texts.
+
+Example, space_before and indent disabled, space_after enabled:
+
+ {"key": "value"}
+
+=head2 relaxed
+
+ $json = $json->relaxed([$enable])
+
+ $enabled = $json->get_relaxed
+
+If C<$enable> is true (or missing), then C<decode> will accept some
+extensions to normal JSON syntax (see below). C<encode> will not be
+affected in anyway. I<Be aware that this option makes you accept invalid
+JSON texts as if they were valid!>. I suggest only to use this option to
+parse application-specific files written by humans (configuration files,
+resource files etc.)
+
+If C<$enable> is false (the default), then C<decode> will only accept
+valid JSON texts.
+
+Currently accepted extensions are:
+
+=over 4
+
+=item * list items can have an end-comma
+
+JSON I<separates> array elements and key-value pairs with commas. This
+can be annoying if you write JSON texts manually and want to be able to
+quickly append elements, so this extension accepts comma at the end of
+such items not just between them:
+
+ [
+ 1,
+ 2, <- this comma not normally allowed
+ ]
+ {
+ "k1": "v1",
+ "k2": "v2", <- this comma not normally allowed
+ }
+
+=item * shell-style '#'-comments
+
+Whenever JSON allows whitespace, shell-style comments are additionally
+allowed. They are terminated by the first carriage-return or line-feed
+character, after which more white-space and comments are allowed.
+
+ [
+ 1, # this comment not allowed in JSON
+ # neither this one...
+ ]
+
+=back
+
+=head2 canonical
+
+ $json = $json->canonical([$enable])
+
+ $enabled = $json->get_canonical
+
+If C<$enable> is true (or missing), then the C<encode> method will output JSON objects
+by sorting their keys. This is adding a comparatively high overhead.
+
+If C<$enable> is false, then the C<encode> method will output key-value
+pairs in the order Perl stores them (which will likely change between runs
+of the same script).
+
+This option is useful if you want the same data structure to be encoded as
+the same JSON text (given the same overall settings). If it is disabled,
+the same hash might be encoded differently even if contains the same data,
+as key-value pairs have no inherent ordering in Perl.
+
+This setting has no effect when decoding JSON texts.
+
+If you want your own sorting routine, you can give a code reference
+or a subroutine name to C<sort_by>. See to C<JSON::PP OWN METHODS>.
+
+=head2 allow_nonref
+
+ $json = $json->allow_nonref([$enable])
+
+ $enabled = $json->get_allow_nonref
+
+If C<$enable> is true (or missing), then the C<encode> method can convert a
+non-reference into its corresponding string, number or null JSON value,
+which is an extension to RFC4627. Likewise, C<decode> will accept those JSON
+values instead of croaking.
+
+If C<$enable> is false, then the C<encode> method will croak if it isn't
+passed an arrayref or hashref, as JSON texts must either be an object
+or array. Likewise, C<decode> will croak if given something that is not a
+JSON object or array.
+
+ JSON::PP->new->allow_nonref->encode ("Hello, World!")
+ => "Hello, World!"
+
+=head2 allow_unknown
+
+ $json = $json->allow_unknown ([$enable])
+
+ $enabled = $json->get_allow_unknown
+
+If $enable is true (or missing), then "encode" will *not* throw an
+exception when it encounters values it cannot represent in JSON (for
+example, filehandles) but instead will encode a JSON "null" value.
+Note that blessed objects are not included here and are handled
+separately by c<allow_nonref>.
+
+If $enable is false (the default), then "encode" will throw an
+exception when it encounters anything it cannot encode as JSON.
+
+This option does not affect "decode" in any way, and it is
+recommended to leave it off unless you know your communications
+partner.
+
+=head2 allow_blessed
+
+ $json = $json->allow_blessed([$enable])
+
+ $enabled = $json->get_allow_blessed
+
+If C<$enable> is true (or missing), then the C<encode> method will not
+barf when it encounters a blessed reference. Instead, the value of the
+B<convert_blessed> option will decide whether C<null> (C<convert_blessed>
+disabled or no C<TO_JSON> method found) or a representation of the
+object (C<convert_blessed> enabled and C<TO_JSON> method found) is being
+encoded. Has no effect on C<decode>.
+
+If C<$enable> is false (the default), then C<encode> will throw an
+exception when it encounters a blessed object.
+
+=head2 convert_blessed
+
+ $json = $json->convert_blessed([$enable])
+
+ $enabled = $json->get_convert_blessed
+
+If C<$enable> is true (or missing), then C<encode>, upon encountering a
+blessed object, will check for the availability of the C<TO_JSON> method
+on the object's class. If found, it will be called in scalar context
+and the resulting scalar will be encoded instead of the object. If no
+C<TO_JSON> method is found, the value of C<allow_blessed> will decide what
+to do.
+
+The C<TO_JSON> method may safely call die if it wants. If C<TO_JSON>
+returns other blessed objects, those will be handled in the same
+way. C<TO_JSON> must take care of not causing an endless recursion cycle
+(== crash) in this case. The name of C<TO_JSON> was chosen because other
+methods called by the Perl core (== not by the user of the object) are
+usually in upper case letters and to avoid collisions with the C<to_json>
+function or method.
+
+This setting does not yet influence C<decode> in any way.
+
+If C<$enable> is false, then the C<allow_blessed> setting will decide what
+to do when a blessed object is found.
+
+=head2 filter_json_object
+
+ $json = $json->filter_json_object([$coderef])
+
+When C<$coderef> is specified, it will be called from C<decode> each
+time it decodes a JSON object. The only argument passed to the coderef
+is a reference to the newly-created hash. If the code references returns
+a single scalar (which need not be a reference), this value
+(i.e. a copy of that scalar to avoid aliasing) is inserted into the
+deserialised data structure. If it returns an empty list
+(NOTE: I<not> C<undef>, which is a valid scalar), the original deserialised
+hash will be inserted. This setting can slow down decoding considerably.
+
+When C<$coderef> is omitted or undefined, any existing callback will
+be removed and C<decode> will not change the deserialised hash in any
+way.
+
+Example, convert all JSON objects into the integer 5:
+
+ my $js = JSON::PP->new->filter_json_object (sub { 5 });
+ # returns [5]
+ $js->decode ('[{}]'); # the given subroutine takes a hash reference.
+ # throw an exception because allow_nonref is not enabled
+ # so a lone 5 is not allowed.
+ $js->decode ('{"a":1, "b":2}');
+
+=head2 filter_json_single_key_object
+
+ $json = $json->filter_json_single_key_object($key [=> $coderef])
+
+Works remotely similar to C<filter_json_object>, but is only called for
+JSON objects having a single key named C<$key>.
+
+This C<$coderef> is called before the one specified via
+C<filter_json_object>, if any. It gets passed the single value in the JSON
+object. If it returns a single value, it will be inserted into the data
+structure. If it returns nothing (not even C<undef> but the empty list),
+the callback from C<filter_json_object> will be called next, as if no
+single-key callback were specified.
+
+If C<$coderef> is omitted or undefined, the corresponding callback will be
+disabled. There can only ever be one callback for a given key.
+
+As this callback gets called less often then the C<filter_json_object>
+one, decoding speed will not usually suffer as much. Therefore, single-key
+objects make excellent targets to serialise Perl objects into, especially
+as single-key JSON objects are as close to the type-tagged value concept
+as JSON gets (it's basically an ID/VALUE tuple). Of course, JSON does not
+support this in any way, so you need to make sure your data never looks
+like a serialised Perl hash.
+
+Typical names for the single object key are C<__class_whatever__>, or
+C<$__dollars_are_rarely_used__$> or C<}ugly_brace_placement>, or even
+things like C<__class_md5sum(classname)__>, to reduce the risk of clashing
+with real hashes.
+
+Example, decode JSON objects of the form C<< { "__widget__" => <id> } >>
+into the corresponding C<< $WIDGET{<id>} >> object:
+
+ # return whatever is in $WIDGET{5}:
+ JSON::PP
+ ->new
+ ->filter_json_single_key_object (__widget__ => sub {
+ $WIDGET{ $_[0] }
+ })
+ ->decode ('{"__widget__": 5')
+
+ # this can be used with a TO_JSON method in some "widget" class
+ # for serialisation to json:
+ sub WidgetBase::TO_JSON {
+ my ($self) = @_;
+
+ unless ($self->{id}) {
+ $self->{id} = ..get..some..id..;
+ $WIDGET{$self->{id}} = $self;
+ }
+
+ { __widget__ => $self->{id} }
+ }

+=head2 shrink
+
+ $json = $json->shrink([$enable])
+
+ $enabled = $json->get_shrink
+
+In JSON::XS, this flag resizes strings generated by either
+C<encode> or C<decode> to their minimum size possible.
+It will also try to downgrade any strings to octet-form if possible.
+
+In JSON::PP, it is noop about resizing strings but tries
+C<utf8::downgrade> to the returned string by C<encode>.

+
+=head2 max_depth
+
+ $json = $json->max_depth([$maximum_nesting_depth])
+
+ $max_depth = $json->get_max_depth
+
+Sets the maximum nesting level (default C<512>) accepted while encoding
+or decoding. If a higher nesting level is detected in JSON text or a Perl
+data structure, then the encoder and decoder will stop and croak at that
+point.
+
+Nesting level is defined by number of hash- or arrayrefs that the encoder
+needs to traverse to reach a given point or the number of C<{> or C<[>
+characters without their matching closing parenthesis crossed to reach a
+given character in a string.
+
+If no argument is given, the highest possible setting will be used, which
+is rarely useful.
+
+See L<JSON::XS/SSECURITY CONSIDERATIONS> for more info on why this is useful.
+
+When a large value (100 or more) was set and it de/encodes a deep nested object/text,
+it may raise a warning 'Deep recursion on subroutine' at the perl runtime phase.
+
+=head2 max_size
+
+ $json = $json->max_size([$maximum_string_size])
+
+ $max_size = $json->get_max_size
+
+Set the maximum length a JSON text may have (in bytes) where decoding is
+being attempted. The default is C<0>, meaning no limit. When C<decode>
+is called on a string that is longer then this many bytes, it will not
+attempt to decode the string but throw an exception. This setting has no
+effect on C<encode> (yet).
+
+If no argument is given, the limit check will be deactivated (same as when
+C<0> is specified).
+
+See L<JSON::XS/SECURITY CONSIDERATIONS> for more info on why this is useful.
+
+=head2 encode
+
+ $json_text = $json->encode($perl_scalar)
+
+Converts the given Perl data structure (a simple scalar or a reference
+to a hash or array) to its JSON representation. Simple scalars will be
+converted into JSON string or number sequences, while references to arrays
+become JSON arrays and references to hashes become JSON objects. Undefined
+Perl values (e.g. C<undef>) become JSON C<null> values.
+References to the integers C<0> and C<1> are converted into C<true> and C<false>.
+
+=head2 decode
+
+ $perl_scalar = $json->decode($json_text)
+
+The opposite of C<encode>: expects a JSON text and tries to parse it,
+returning the resulting simple scalar or reference. Croaks on error.
+
+JSON numbers and strings become simple Perl scalars. JSON arrays become
+Perl arrayrefs and JSON objects become Perl hashrefs. C<true> becomes
+C<1> (C<JSON::true>), C<false> becomes C<0> (C<JSON::false>) and
+C<null> becomes C<undef>.
+
+=head2 decode_prefix
+
+ ($perl_scalar, $characters) = $json->decode_prefix($json_text)
+
+This works like the C<decode> method, but instead of raising an exception
+when there is trailing garbage after the first JSON object, it will
+silently stop parsing there and return the number of characters consumed
+so far.
+
+ JSON->new->decode_prefix ("[1] the tail")
+ => ([], 3)
+
+=head1 INCREMENTAL PARSING
+
+Most of this section are copied and modified from L<JSON::XS/INCREMENTAL PARSING>.
+
+In some cases, there is the need for incremental parsing of JSON texts.
+This module does allow you to parse a JSON stream incrementally.
+It does so by accumulating text until it has a full JSON object, which
+it then can decode. This process is similar to using C<decode_prefix>
+to see if a full JSON object is available, but is much more efficient
+(and can be implemented with a minimum of method calls).
+
+This module will only attempt to parse the JSON text once it is sure it
+has enough text to get a decisive result, using a very simple but
+truly incremental parser. This means that it sometimes won't stop as
+early as the full parser, for example, it doesn't detect parenthesis
+mismatches. The only thing it guarantees is that it starts decoding as
+soon as a syntactically valid JSON text has been seen. This means you need
+to set resource limits (e.g. C<max_size>) to ensure the parser will stop
+parsing in the presence if syntax errors.
+
+The following methods implement this incremental parser.
+
+=head2 incr_parse
+
+ $json->incr_parse( [$string] ) # void context
+
+ $obj_or_undef = $json->incr_parse( [$string] ) # scalar context
+
+ @obj_or_empty = $json->incr_parse( [$string] ) # list context
+
+This is the central parsing function. It can both append new text and
+extract objects from the stream accumulated so far (both of these
+functions are optional).
+
+If C<$string> is given, then this string is appended to the already
+existing JSON fragment stored in the C<$json> object.
+
+After that, if the function is called in void context, it will simply
+return without doing anything further. This can be used to add more text
+in as many chunks as you want.
+
+If the method is called in scalar context, then it will try to extract
+exactly I<one> JSON object. If that is successful, it will return this
+object, otherwise it will return C<undef>. If there is a parse error,
+this method will croak just as C<decode> would do (one can then use
+C<incr_skip> to skip the erroneous part). This is the most common way of
+using the method.
+
+And finally, in list context, it will try to extract as many objects
+from the stream as it can find and return them, or the empty list
+otherwise. For this to work, there must be no separators between the JSON
+objects or arrays, instead they must be concatenated back-to-back. If
+an error occurs, an exception will be raised as in the scalar context
+case. Note that in this case, any previously-parsed JSON texts will be
+lost.
+
+Example: Parse some JSON arrays/objects in a given string and return them.
+
+ my @objs = JSON->new->incr_parse ("[5][7][1,2]");
+
+=head2 incr_text
+
+ $lvalue_string = $json->incr_text
+
+This method returns the currently stored JSON fragment as an lvalue, that
+is, you can manipulate it. This I<only> works when a preceding call to
+C<incr_parse> in I<scalar context> successfully returned an object. Under
+all other circumstances you must not call this function (I mean it.
+although in simple tests it might actually work, it I<will> fail under
+real world conditions). As a special exception, you can also call this
+method before having parsed anything.
+
+This function is useful in two cases: a) finding the trailing text after a
+JSON object or b) parsing multiple JSON objects separated by non-JSON text
+(such as commas).
+
+ $json->incr_text =~ s/\s*,\s*//;
+
+In Perl 5.005, C<lvalue> attribute is not available.
+You must write codes like the below:
+
+ $string = $json->incr_text;
+ $string =~ s/\s*,\s*//;
+ $json->incr_text( $string );
+
+=head2 incr_skip
+
+ $json->incr_skip
+
+This will reset the state of the incremental parser and will remove the
+parsed text from the input buffer. This is useful after C<incr_parse>
+died, in which case the input buffer and incremental parser state is left
+unchanged, to skip the text parsed so far and to reset the parse state.
+
+=head2 incr_reset
+
+ $json->incr_reset
+
+This completely resets the incremental parser, that is, after this call,
+it will be as if the parser had never parsed anything.
+
+This is useful if you want to repeatedly parse JSON objects and want to
+ignore any trailing data, which means you have to reset the parser after
+each successful decode.
+
+See to L<JSON::XS/INCREMENTAL PARSING> for examples.
+
+
+=head1 JSON::PP OWN METHODS
+
+=head2 allow_singlequote
+
+ $json = $json->allow_singlequote([$enable])
+
+If C<$enable> is true (or missing), then C<decode> will accept
+JSON strings quoted by single quotations that are invalid JSON
+format.
+
+ $json->allow_singlequote->decode({"foo":'bar'});
+ $json->allow_singlequote->decode({'foo':"bar"});
+ $json->allow_singlequote->decode({'foo':'bar'});
+
+As same as the C<relaxed> option, this option may be used to parse
+application-specific files written by humans.
+
+
+=head2 allow_barekey
+
+ $json = $json->allow_barekey([$enable])
+
+If C<$enable> is true (or missing), then C<decode> will accept
+bare keys of JSON object that are invalid JSON format.
+
+As same as the C<relaxed> option, this option may be used to parse
+application-specific files written by humans.
+
+ $json->allow_barekey->decode('{foo:"bar"}');
+
+=head2 allow_bignum
+
+ $json = $json->allow_bignum([$enable])
+
+If C<$enable> is true (or missing), then C<decode> will convert
+the big integer Perl cannot handle as integer into a L<Math::BigInt>
+object and convert a floating number (any) into a L<Math::BigFloat>.
+
+On the contrary, C<encode> converts C<Math::BigInt> objects and C<Math::BigFloat>
+objects into JSON numbers with C<allow_blessed> enable.
+
+ $json->allow_nonref->allow_blessed->allow_bignum;
+ $bigfloat = $json->decode('2.000000000000000000000000001');
+ print $json->encode($bigfloat);
+ # => 2.000000000000000000000000001
+
+See to L<JSON::XS/MAPPING> about the normal conversion of JSON number.
+
+=head2 loose
+
+ $json = $json->loose([$enable])
+
+The unescaped [\x00-\x1f\x22\x2f\x5c] strings are invalid in JSON strings
+and the module doesn't allow to C<decode> to these (except for \x2f).
+If C<$enable> is true (or missing), then C<decode> will accept these
+unescaped strings.
+
+ $json->loose->decode(qq|["abc
+ def"]|);
+
+See L<JSON::XS/SSECURITY CONSIDERATIONS>.
+
+=head2 escape_slash
+
+ $json = $json->escape_slash([$enable])
+
+According to JSON Grammar, I<slash> (U+002F) is escaped. But default
+JSON::PP (as same as JSON::XS) encodes strings without escaping slash.
+
+If C<$enable> is true (or missing), then C<encode> will escape slashes.
+
+=head2 indent_length
+
+ $json = $json->indent_length($length)
+
+JSON::XS indent space length is 3 and cannot be changed.
+JSON::PP set the indent space length with the given $length.
+The default is 3. The acceptable range is 0 to 15.
+
+=head2 sort_by
+
+ $json = $json->sort_by($function_name)
+ $json = $json->sort_by($subroutine_ref)
+
+If $function_name or $subroutine_ref are set, its sort routine are used
+in encoding JSON objects.
+
+ $js = $pc->sort_by(sub { $JSON::PP::a cmp $JSON::PP::b })->encode($obj);
+ # is($js, q|{"a":1,"b":2,"c":3,"d":4,"e":5,"f":6,"g":7,"h":8,"i":9}|);
+
+ $js = $pc->sort_by('own_sort')->encode($obj);
+ # is($js, q|{"a":1,"b":2,"c":3,"d":4,"e":5,"f":6,"g":7,"h":8,"i":9}|);
+
+ sub JSON::PP::own_sort { $JSON::PP::a cmp $JSON::PP::b }
+
+As the sorting routine runs in the JSON::PP scope, the given
+subroutine name and the special variables C<$a>, C<$b> will begin
+'JSON::PP::'.
+
+If $integer is set, then the effect is same as C<canonical> on.

+=head1 MAPPING
+
+This section is copied from JSON::XS and modified to C<JSON::PP>.
+JSON::XS and JSON::PP mapping mechanisms are almost equivalent.
+
+See to L<JSON::XS/MAPPING>.
+
+=head2 JSON -> PERL
+
+=over 4
+
+=item object
+
+A JSON object becomes a reference to a hash in Perl. No ordering of object
+keys is preserved (JSON does not preserver object key ordering itself).
+
+=item array
+
+A JSON array becomes a reference to an array in Perl.
+
+=item string
+
+A JSON string becomes a string scalar in Perl - Unicode codepoints in JSON
+are represented by the same codepoints in the Perl string, so no manual
+decoding is necessary.
+
+=item number
+
+A JSON number becomes either an integer, numeric (floating point) or
+string scalar in perl, depending on its range and any fractional parts. On
+the Perl level, there is no difference between those as Perl handles all
+the conversion details, but an integer may take slightly less memory and
+might represent more values exactly than floating point numbers.
+
+If the number consists of digits only, C<JSON> will try to represent
+it as an integer value. If that fails, it will try to represent it as
+a numeric (floating point) value if that is possible without loss of
+precision. Otherwise it will preserve the number as a string value (in
+which case you lose roundtripping ability, as the JSON number will be
+re-encoded to a JSON string).
+
+Numbers containing a fractional or exponential part will always be
+represented as numeric (floating point) values, possibly at a loss of
+precision (in which case you might lose perfect roundtripping ability, but
+the JSON number will still be re-encoded as a JSON number).
+
+Note that precision is not accuracy - binary floating point values cannot
+represent most decimal fractions exactly, and when converting from and to
+floating point, C<JSON> only guarantees precision up to but not including
+the least significant bit.
+
+When C<allow_bignum> is enable, the big integers
+and the numeric can be optionally converted into L<Math::BigInt> and
+L<Math::BigFloat> objects.
+
+=item true, false
+
+These JSON atoms become C<JSON::PP::true> and C<JSON::PP::false>,
+respectively. They are overloaded to act almost exactly like the numbers
+C<1> and C<0>. You can check whether a scalar is a JSON boolean by using
+the C<JSON::is_bool> function.
+
+ print JSON::PP::true . "\n";
+ => true
+ print JSON::PP::true + 1;
+ => 1
+
+ ok(JSON::true eq '1');
+ ok(JSON::true == 1);
+
+C<JSON> will install these missing overloading features to the backend modules.
+
+
+=item null
+
+A JSON null atom becomes C<undef> in Perl.
+
+C<JSON::PP::null> returns C<undef>.
+
+=back
+
+
+=head2 PERL -> JSON
+
+The mapping from Perl to JSON is slightly more difficult, as Perl is a
+truly typeless language, so we can only guess which JSON type is meant by
+a Perl value.
+
+=over 4
+
+=item hash references
+
+Perl hash references become JSON objects. As there is no inherent ordering
+in hash keys (or JSON objects), they will usually be encoded in a
+pseudo-random order that can change between runs of the same program but
+stays generally the same within a single run of a program. C<JSON>
+optionally sort the hash keys (determined by the I<canonical> flag), so
+the same data structure will serialise to the same JSON text (given same
+settings and version of JSON::XS), but this incurs a runtime overhead
+and is only rarely useful, e.g. when you want to compare some JSON text
+against another for equality.
+
+
+=item array references
+
+Perl array references become JSON arrays.
+
+=item other references
+
+Other unblessed references are generally not allowed and will cause an
+exception to be thrown, except for references to the integers C<0> and
+C<1>, which get turned into C<false> and C<true> atoms in JSON. You can
+also use C<JSON::false> and C<JSON::true> to improve readability.
+
+ to_json [\0,JSON::PP::true] # yields [false,true]
+
+=item JSON::PP::true, JSON::PP::false, JSON::PP::null
+
+These special values become JSON true and JSON false values,
+respectively. You can also use C<\1> and C<\0> directly if you want.
+
+JSON::PP::null returns C<undef>.
+
+=item blessed objects
+
+Blessed objects are not directly representable in JSON. See the
+C<allow_blessed> and C<convert_blessed> methods on various options on
+how to deal with this: basically, you can choose between throwing an
+exception, encoding the reference as if it weren't blessed, or provide
+your own serialiser method.
+
+See to L<convert_blessed>.
+
+=item simple scalars
+
+Simple Perl scalars (any scalar that is not a reference) are the most
+difficult objects to encode: JSON::XS and JSON::PP will encode undefined scalars as
+JSON C<null> values, scalars that have last been used in a string context
+before encoding as JSON strings, and anything else as number value:
+
+ # dump as number
+ encode_json [2] # yields [2]
+ encode_json [-3.0e17] # yields [-3e+17]
+ my $value = 5; encode_json [$value] # yields [5]
+
+ # used as string, so dump as string
+ print $value;
+ encode_json [$value] # yields ["5"]
+
+ # undef becomes null
+ encode_json [undef] # yields [null]
+
+You can force the type to be a string by stringifying it:
+
+ my $x = 3.1; # some variable containing a number
+ "$x"; # stringified
+ $x .= ""; # another, more awkward way to stringify
+ print $x; # perl does it for you, too, quite often
+
+You can force the type to be a number by numifying it:
+
+ my $x = "3"; # some variable containing a string
+ $x += 0; # numify it, ensuring it will be dumped as a number
+ $x *= 1; # same thing, the choice is yours.
+
+You can not currently force the type in other, less obscure, ways.
+
+Note that numerical precision has the same meaning as under Perl (so
+binary to decimal conversion follows the same rules as in Perl, which
+can differ to other languages). Also, your perl interpreter might expose
+extensions to the floating point numbers of your platform, such as
+infinities or NaN's - these cannot be represented in JSON, and it is an
+error to pass those in.
+
+=item Big Number
+
+When C<allow_bignum> is enable,
+C<encode> converts C<Math::BigInt> objects and C<Math::BigFloat>
+objects into JSON numbers.
+
+
+=back
+
+=head1 UNICODE HANDLING ON PERLS
+
+If you do not know about Unicode on Perl well,
+please check L<JSON::XS/A FEW NOTES ON UNICODE AND PERL>.
+
+=head2 Perl 5.8 and later
+
+Perl can handle Unicode and the JSON::PP de/encode methods also work properly.
+
+ $json->allow_nonref->encode(chr hex 3042);
+ $json->allow_nonref->encode(chr hex 12345);
+
+Returns C<"\u3042"> and C<"\ud808\udf45"> respectively.
+
+ $json->allow_nonref->decode('"\u3042"');
+ $json->allow_nonref->decode('"\ud808\udf45"');
+
+Returns UTF-8 encoded strings with UTF8 flag, regarded as C<U+3042> and C<U+12345>.
+
+Note that the versions from Perl 5.8.0 to 5.8.2, Perl built-in C<join> was broken,
+so JSON::PP wraps the C<join> with a subroutine. Thus JSON::PP works slow in the versions.
+
+
+=head2 Perl 5.6
+
+Perl can handle Unicode and the JSON::PP de/encode methods also work.
+
+=head2 Perl 5.005
+
+Perl 5.005 is a byte semantics world -- all strings are sequences of bytes.
+That means the unicode handling is not available.
+
+In encoding,
+
+ $json->allow_nonref->encode(chr hex 3042); # hex 3042 is 12354.
+ $json->allow_nonref->encode(chr hex 12345); # hex 12345 is 74565.
+
+Returns C<B> and C<E>, as C<chr> takes a value more than 255, it treats
+as C<$value % 256>, so the above codes are equivalent to :
+
+ $json->allow_nonref->encode(chr 66);
+ $json->allow_nonref->encode(chr 69);
+
+In decoding,
+
+ $json->decode('"\u00e3\u0081\u0082"');
+
+The returned is a byte sequence C<0xE3 0x81 0x82> for UTF-8 encoded
+japanese character (C<HIRAGANA LETTER A>).
+And if it is represented in Unicode code point, C<U+3042>.
+
+Next,
+
+ $json->decode('"\u3042"');
+
+We ordinary expect the returned value is a Unicode character C<U+3042>.
+But here is 5.005 world. This is C<0xE3 0x81 0x82>.
+
+ $json->decode('"\ud808\udf45"');
+
+This is not a character C<U+12345> but bytes - C<0xf0 0x92 0x8d 0x85>.

=head1 NAME
-JSON - parse and convert to JSON (JavaScript Object Notation).
+JSON - JSON (JavaScript Object Notation) encoder/decoder
=head1 SYNOPSIS
- use JSON;
+ use JSON; # imports encode_json, decode_json, to_json and from_json.
+
+ # simple and fast interfaces (expect/generate UTF-8)
+
+ $utf8_encoded_json_text = encode_json $perl_hash_or_arrayref;
+ $perl_hash_or_arrayref = decode_json $utf8_encoded_json_text;
+
+ # OO-interface
+
+ $json = JSON->new->allow_nonref;
+
+ $json_text = $json->encode( $perl_scalar );
+ $perl_scalar = $json->decode( $json_text );
- $obj = {
- id => ["foo", "bar", { aa => 'bb'}],
- hoge => 'boge'
- };
+ $pretty_printed = $json->pretty->encode( $perl_scalar ); # pretty-printing
- $js = objToJson($obj);
- # this is {"id":["foo","bar",{"aa":"bb"}],"hoge":"boge"}.
- $obj = jsonToObj($js);
- # the data structure was restored.
+ # If you want to use PP only support features, call with '-support_by_pp'
+ # When XS unsupported feature is enable, using PP (de|en)code instead of XS ones.
- # OOP
+ use JSON -support_by_pp;
- my $json = new JSON;
+ # option-acceptable interfaces (expect/generate UNICODE by default)
- $obj = {id => 'foo', method => 'echo', params => ['a','b']};
- $js = $json->objToJson($obj);
- $obj = $json->jsonToObj($js);
+ $json_text = to_json( $perl_scalar, { ascii => 1, pretty => 1 } );
+ $perl_scalar = from_json( $json_text, { utf8 => 1 } );
- # pretty-printing
- $js = $json->objToJson($obj, {pretty => 1, indent => 2});
+ # Between (en|de)code_json and (to|from)_json, if you want to write
+ # a code which communicates to an outer world (encoded in UTF-8),
+ # recommend to use (en|de)code_json.
+
+=head1 VERSION
+
+ 2.90
- $json = JSON->new(pretty => 1, delimiter => 0);
- $json->objToJson($obj);
+This version is compatible with JSON::XS B<2.34> and later.
+(Not yet compatble to JSON::XS B<3.0x>.)
-=head1 TRANSITION PLAN
+=head1 NOTE
-In the next large update version, JSON and JSONRPC modules are split.
+JSON::PP was earlier included in the C<JSON> distribution, but
+has since Perl 5.14 been a core module. For this reason,
+L<JSON::PP> was removed from the JSON distribution and can now
+be found also in the Perl5 repository at
- JSON::Parser and JSON::Converter are deleted from JSON dist.
- JSON and JSON::PP in JSON dist.
+=over
- JSON becomes wrapper to JSON::XS and/or JSON::PP.
+=item * L<http://perl5.git.perl.org/perl.git>
- JSONRPC* and Apache::JSONRPC are deleted from JSON dist.
- JSONRPC::Client, JSONRPC::Server and JSONRPC::Procedure in JSON::RPC dist.
+=back
- Modules in JSON::RPC dist supports JSONRPC protocol v1.1 and 1.0.
+(The newest JSON::PP version still exists in CPAN.)
+Instead, the C<JSON> distribution will include JSON::backportPP
+for backwards computability. JSON.pm should thus work as it did
+before.
=head1 DESCRIPTION
-This module converts between JSON (JavaScript Object Notation) and Perl
-data structure into each other.
-For JSON, See to http://www.crockford.com/JSON/.
+ *************************** CAUTION **************************************
+ * *
+ * INCOMPATIBLE CHANGE (JSON::XS version 2.90) *
+ * *
+ * JSON.pm had patched JSON::XS::Boolean and JSON::PP::Boolean internally *
+ * on loading time for making these modules inherit JSON::Boolean. *
+ * But since JSON::XS v3.0 it use Types::Serialiser as boolean class. *
+ * Then now JSON.pm breaks boolean classe overload features and *
+ * -support_by_pp if JSON::XS v3.0 or later is installed. *
+ * *
+ * JSON::true and JSON::false returned JSON::Boolean objects. *
+ * For workaround, they return JSON::PP::Boolean objects in this version. *
+ * *
+ * isa_ok(JSON::true, 'JSON::PP::Boolean'); *
+ * *
+ * And it discards a feature: *
+ * *
+ * ok(JSON::true eq 'true'); *
+ * *
+ * In other word, JSON::PP::Boolean overload numeric only. *
+ * *
+ * ok( JSON::true == 1 ); *
+ * *
+ **************************************************************************
+ ************************** CAUTION ********************************
+ * This is 'JSON module version 2' and there are many differences *
+ * to version 1.xx *

-=head1 METHODS
+JSON (JavaScript Object Notation) is a simple data format.
+See to L<http://www.json.org/> and C<RFC4627>(L<http://www.ietf.org/rfc/rfc4627.txt>).
-=over 4
+This module converts Perl data structures to JSON and vice versa using either
+L<JSON::XS> or L<JSON::PP>.
-=item new()
+JSON::XS is the fastest and most proper JSON module on CPAN which must be
+compiled and installed in your environment.
+JSON::PP is a pure-Perl module which is bundled in this distribution and
+has a strong compatibility to JSON::XS.
-=item new( %options )
+This module try to use JSON::XS by default and fail to it, use JSON::PP instead.
+So its features completely depend on JSON::XS or JSON::PP.
-returns a JSON object. The object delegates the converting and parsing process
-to L<JSON::Converter> and L<JSON::Parser>.
+See to L<BACKEND MODULE DECISION>.
- my $json = new JSON;
+To distinguish the module name 'JSON' and the format type JSON,
+the former is quoted by CE<lt>E<gt> (its results vary with your using media),
+and the latter is left just as it is.
-C<new> can take some options.
+Module name : C<JSON>
- my $json = new JSON (autoconv => 0, pretty => 1);
+Format type : JSON
-Following options are supported:
+=head2 FEATURES
-=over 4
+=over
-=item autoconv
+=item * correct unicode handling
-See L</AUTOCONVERT> for more info.
+This module (i.e. backend modules) knows how to handle Unicode, documents
+how and when it does so, and even documents what "correct" means.
-=item skipinvalid
+Even though there are limitations, this feature is available since Perl version 5.6.
-C<objToJson()> does C<die()> when it encounters any invalid data
-(for instance, coderefs). If C<skipinvalid> is set with true,
-the function convets these invalid data into JSON format's C<null>.
+JSON::XS requires Perl 5.8.2 (but works correctly in 5.8.8 or later), so in older versions
+C<JSON> should call JSON::PP as the backend which can be used since Perl 5.005.
-=item execcoderef
+With Perl 5.8.x JSON::PP works, but from 5.8.0 to 5.8.2, because of a Perl side problem,
+JSON::PP works slower in the versions. And in 5.005, the Unicode handling is not available.
+See to L<JSON::PP/UNICODE HANDLING ON PERLS> for more information.
-C<objToJson()> does C<die()> when it encounters any code reference.
-However, if C<execcoderef> is set with true, executes the coderef
-and uses returned value.
+See also to L<JSON::XS/A FEW NOTES ON UNICODE AND PERL>
+and L<JSON::XS/ENCODING/CODESET_FLAG_NOTES>.
-=item pretty
-See L</PRETTY PRINTING> for more info.
+=item * round-trip integrity
-=item indent
+When you serialise a perl data structure using only data types supported
+by JSON and Perl, the deserialised data structure is identical on the Perl
+level. (e.g. the string "2.0" doesn't suddenly become "2" just because
+it looks like a number). There I<are> minor exceptions to this, read the
+L</MAPPING> section below to learn about those.
-See L</PRETTY PRINTING> for more info.
-=item delimiter
+=item * strict checking of JSON correctness
-See L</PRETTY PRINTING> for more info.
+There is no guessing, no generating of illegal JSON texts by default,
+and only JSON is accepted as input by default (the latter is a security
+feature).
-=item keysort
+See to L<JSON::XS/FEATURES> and L<JSON::PP/FEATURES>.
-See L</HASH KEY SORT ORDER> for more info.
+=item * fast
-=item convblessed
+This module returns a JSON::XS object itself if available.
+Compared to other JSON modules and other serialisers such as Storable,
+JSON::XS usually compares favorably in terms of speed, too.
-See L</BLESSED OBJECT> for more info.
+If not available, C<JSON> returns a JSON::PP object instead of JSON::XS and
+it is very slow as pure-Perl.
-=item selfconvert
+=item * simple to use
-See L</BLESSED OBJECT> for more info.
+This module has both a simple functional interface as well as an
+object oriented interface interface.
-=item singlequote
+=item * reasonably versatile output formats
-See L</CONVERT WITH SINGLE QUOTES> for more info.
+You can choose between the most compact guaranteed-single-line format possible
+(nice for simple line-based protocols), a pure-ASCII format (for when your transport
+is not 8-bit clean, still supports the whole Unicode range), or a pretty-printed
+format (for when you want to read that stuff). Or you can combine those features
+in whatever way you like.
-=item quotapos
+=back
-See L</SINGLE QUOTATION OPTION>.
+=head1 FUNCTIONAL INTERFACE
-=back
+Some documents are copied and modified from L<JSON::XS/FUNCTIONAL INTERFACE>.

+=head2 encode_json
-=item objToJson( $object )
+ $json_text = encode_json $perl_scalar
-=item objToJson( $object, $hashref )
+Converts the given Perl data structure to a UTF-8 encoded, binary string.
-takes perl data structure (basically, they are scalars, arrayrefs and hashrefs)
-and returns JSON formated string.
+This function call is functionally identical to:

- my $js = $json->objToJson($obj);
- # [1,2,{"foo":"bar"}]
+ $json_text = JSON->new->utf8->encode($perl_scalar)
-By default, returned string is one-line. However, you can get pretty-printed
-data with C<pretty> option. Please see below L</PRETTY PRINTING>.

+ $perl_scalar = decode_json $json_text
-=item jsonToObj( $js )
+The opposite of C<encode_json>: expects an UTF-8 (binary) string and tries
+to parse that as an UTF-8 encoded JSON text, returning the resulting

+=head2 JSON::is_bool
+ $is_boolean = JSON::is_bool($scalar)
-=back
+Returns true if the passed scalar represents either JSON::true or

+=head2 JSON::true
- (JSON) {"param" : []}
- ( => Perl) {'param' => []};
-
- (JSON) {"param" : {}}
- ( => Perl) {'param' => {}};

- ( => Perl) {'param' => 'string'};
-
- JSON {"param" : null}
- => Perl {'param' => bless( {'value' => undef}, 'JSON::NotString' )};
- or {'param' => undef}
-
- (JSON) {"param" : true}
- ( => Perl) {'param' => bless( {'value' => 'true'}, 'JSON::NotString' )};
- or {'param' => 1}
-
- (JSON) {"param" : false}

- (JSON) {"param" : 010}
- ( => Perl) {'param' => 8};
+=head2 JSON::false
-These JSON::NotString objects are overloaded so you don't care about.
-Since 1.00, L</UnMapping option> is added. When that option is set,
-{"param" : null} will be converted into {'param' => undef}, insted of
-{'param' => bless( {'value' => undef}, 'JSON::NotString' )}.
+Returns JSON false value which is blessed object.
+It C<isa> JSON::Boolean object.
+=head2 JSON::null
-Perl's C<undef> is converted to 'null'.
+Returns C<undef>.
+See L<MAPPING>, below, for more information on how JSON values are mapped to
+Perl.
-=head1 PRETTY PRINTING
+=head1 HOW DO I DECODE A DATA FROM OUTER AND ENCODE TO OUTER
-If you'd like your JSON output to be pretty-printed, pass the C<pretty>
-parameter to objToJson(). You can affect the indentation (which defaults to 2)
-by passing the C<indent> parameter to objToJson().
+This section supposes that your perl version is 5.8 or later.
- my $str = $json->objToJson($obj, {pretty => 1, indent => 4});
+If you know a JSON text from an outer world - a network, a file content, and so on,
+is encoded in UTF-8, you should use C<decode_json> or C<JSON> module object
+with C<utf8> enable. And the decoded result will contain UNICODE characters.
-In addition, you can set some number to C<delimiter> option.
-The available numbers are only 0, 1 and 2.
-In pretty-printing mode, when C<delimiter> is 1, one space is added
-after ':' in object keys. If C<delimiter> is 2, it is ' : ' and
-0 is ':' (default is 2). If you give 3 or more to it, the value
-is taken as 2.
+ # from network
+ my $json = JSON->new->utf8;
+ my $json_text = CGI->new->param( 'json_data' );
+ my $perl_scalar = $json->decode( $json_text );
+
+ # from file content
+ local $/;
+ open( my $fh, '<', 'json.data' );
+ $json_text = <$fh>;
+ $perl_scalar = decode_json( $json_text );
+If an outer data is not encoded in UTF-8, firstly you should C<decode> it.
-=head1 AUTOCONVERT
+ use Encode;
+ local $/;
+ open( my $fh, '<', 'json.data' );
+ my $encoding = 'cp932';
+ my $unicode_json_text = decode( $encoding, <$fh> ); # UNICODE
+
+ # or you can write the below code.
+ #
+ # open( my $fh, "<:encoding($encoding)", 'json.data' );
+ # $unicode_json_text = <$fh>;
-By default, $JSON::AUTOCONVERT is true.
+In this case, C<$unicode_json_text> is of course UNICODE string.
+So you B<cannot> use C<decode_json> nor C<JSON> module object with C<utf8> enable.
+Instead of them, you use C<JSON> module object with C<utf8> disable or C<from_json>.
- (Perl) {num => 10.02}
- ( => JSON) {"num" : 10.02}
+ $perl_scalar = $json->utf8(0)->decode( $unicode_json_text );
+ # or
+ $perl_scalar = from_json( $unicode_json_text );
-it is not C<{"num" : "10.02"}>.
+Or C<encode 'utf8'> and C<decode_json>:
-But set false value with $JSON::AUTOCONVERT:
+ $perl_scalar = decode_json( encode( 'utf8', $unicode_json_text ) );
+ # this way is not efficient.
- (Perl) {num => 10.02}
- ( => JSON) {"num" : "10.02"}
+And now, you want to convert your C<$perl_scalar> into JSON data and
+send it to an outer world - a network or a file content, and so on.
-it is not C<{"num" : 10.02}>.
+Your data usually contains UNICODE strings and you want the converted data to be encoded
+in UTF-8, you should use C<encode_json> or C<JSON> module object with C<utf8> enable.
-You can explicitly sepcify:
+ print encode_json( $perl_scalar ); # to a network? file? or display?
+ # or
+ print $json->utf8->encode( $perl_scalar );
- $obj = {
- id => JSON::Number(10.02),
- bool1 => JSON::True,
- bool2 => JSON::False,
- noval => JSON::Null,
- };
+If C<$perl_scalar> does not contain UNICODE but C<$encoding>-encoded strings
+for some reason, then its characters are regarded as B<latin1> for perl
+(because it does not concern with your $encoding).
+You B<cannot> use C<encode_json> nor C<JSON> module object with C<utf8> enable.
+Instead of them, you use C<JSON> module object with C<utf8> disable or C<to_json>.
+Note that the resulted text is a UNICODE string but no problem to print it.
- $json->objToJson($obj);
- # {"noval" : null, "bool2" : false, "bool1" : true, "id" : 10.02}
+ # $perl_scalar contains $encoding encoded string values
+ $unicode_json_text = $json->utf8(0)->encode( $perl_scalar );
+ # or
+ $unicode_json_text = to_json( $perl_scalar );
+ # $unicode_json_text consists of characters less than 0x100
+ print $unicode_json_text;
-C<JSON::Number()> returns C<undef> when an argument invalid format.
+Or C<decode $encoding> all string values and C<encode_json>:
-=head1 UNMAPPING OPTION
+ $perl_scalar->{ foo } = decode( $encoding, $perl_scalar->{ foo } );
+ # ... do it to each string values, then encode_json
+ $json_text = encode_json( $perl_scalar );
-By default, $JSON::UnMapping is false and JSON::Parser converts
-C<null>, C<true>, C<false> into C<JSON::NotString> objects.
-You can set true into $JSON::UnMapping to stop the mapping function.
-In that case, JSON::Parser will convert C<null>, C<true>, C<false>
-into C<undef>, 1, 0.
+This method is a proper way but probably not efficient.
-=head1 BARE KEY OPTION
+See to L<Encode>, L<perluniintro>.
-You can set a true value into $JSON::BareKey for JSON::Parser to parse
-bare keys of objects.
- local $JSON::BareKey = 1;
- $obj = jsonToObj('{foo:"bar"}');
+=head1 COMMON OBJECT-ORIENTED INTERFACE
-=head1 SINGLE QUOTATION OPTION
+=head2 new
-You can set a true value into $JSON::QuotApos for JSON::Parser to parse
-any keys and values quoted by single quotations.
+ $json = JSON->new
- local $JSON::QuotApos = 1;
- $obj = jsonToObj(q|{"foo":'bar'}|);
- $obj = jsonToObj(q|{'foo':'bar'}|);
+Returns a new C<JSON> object inherited from either JSON::XS or JSON::PP
+that can be used to de/encode JSON strings.
-With $JSON::BareKey:
+All boolean flags described below are by default I<disabled>.
- local $JSON::BareKey = 1;
- local $JSON::QuotApos = 1;
- $obj = jsonToObj(q|{foo:'bar'}|);
+The mutators for flags all return the JSON object again and thus calls can
+be chained:
-=head1 HASH KEY SORT ORDER
+ my $json = JSON->new->utf8->space_after->encode({a => [1,2]})
+ => {"a": [1, 2]}
-By default objToJSON will serialize hashes with their keys in random
-order. To control the ordering of hash keys, you can provide a standard
-'sort' function that will be used to control how hashes are converted.
+=head2 ascii
-You can provide either a fully qualified function name or a CODEREF to
-$JSON::KeySort or $obj->keysort.
+ $json = $json->ascii([$enable])
+
+ $enabled = $json->get_ascii
-If you give any integers (excluded 0), the sort function will work as:
+If $enable is true (or missing), then the encode method will not generate characters outside
+the code range 0..127. Any Unicode characters outside that range will be escaped using either
+a single \uXXXX or a double \uHHHH\uLLLLL escape sequence, as per RFC4627.
- sub { $a cmp $b }
+If $enable is false, then the encode method will not escape Unicode characters unless
+required by the JSON syntax or other flags. This results in a faster and more compact format.
-Note that since the sort function is external to the JSON module the
-magical $a and $b arguments will not be in the same package. In order
-to gain access to the sorting arguments, you must either:
+This feature depends on the used Perl version and environment.
- o use the ($$) prototype (slow)
- o Fully qualify $a and $b from the JSON::Converter namespace
+See to L<JSON::PP/UNICODE HANDLING ON PERLS> if the backend is PP.
-See the documentation on sort for more information.
+ JSON->new->ascii(1)->encode([chr 0x10401])

- local $JSON::KeySort = 'My::Package::sort_function';
+=head2 latin1
- or
+ $json = $json->latin1([$enable])
+
+ $enabled = $json->get_latin1
- local $JSON::KeySort = \&_some_function;
+If $enable is true (or missing), then the encode method will encode the resulting JSON
+text as latin1 (or iso-8859-1), escaping any characters outside the code range 0..255.
- sub sort_function {
- $JSON::Converter::a cmp $JSON::Converter::b;
- }
+If $enable is false, then the encode method will not escape Unicode characters
+unless required by the JSON syntax or other flags.
- or
+ JSON->new->latin1->encode (["\x{89}\x{abc}"]
+ => ["\x{89}\\u0abc"] # (perl syntax, U+abc escaped, U+89 not)
- sub sort_function ($$) {
- my ($a, $b) = @_;
+=head2 utf8
- $a cmp $b
- }
+ $json = $json->utf8([$enable])
+
+ $enabled = $json->get_utf8
-=head1 BLESSED OBJECT
+If $enable is true (or missing), then the encode method will encode the JSON result
+into UTF-8, as required by many protocols, while the decode method expects to be handled
+an UTF-8-encoded string. Please note that UTF-8-encoded strings do not contain any
+characters outside the range 0..255, they are thus useful for bytewise/binary I/O.
-By default, JSON::Converter doesn't deal with any blessed object
-(returns C<undef> or C<null> in the JSON format).
-If you use $JSON::ConvBlessed or C<convblessed> option,
-the module can convert most blessed object (hashref or arrayref).
+In future versions, enabling this option might enable autodetection of the UTF-16 and UTF-32
+encoding families, as described in RFC4627.
- local $JSON::ConvBlessed = 1;
- print objToJson($blessed);
+If $enable is false, then the encode method will return the JSON string as a (non-encoded)
+Unicode string, while decode expects thus a Unicode string. Any decoding or encoding
+(e.g. to UTF-8 or UTF-16) needs to be done yourself, e.g. using the Encode module.
-This option slows down the converting speed.
-If you use $JSON::SelfConvert or C<selfconvert> option,
-the module will test for a C<toJson()> method on the object,
-and will rely on this method to obtain the converted value of
-the object.
+Example, output UTF-16BE-encoded JSON:
-=head1 UTF8
+ use Encode;
+ $jsontext = encode "UTF-16BE", JSON::XS->new->encode ($object);
-You can set a true value into $JSON::UTF8 for JSON::Parser
-and JSON::Converter to set UTF8 flag into strings contain utf8.
+Example, decode UTF-32LE-encoded JSON:
+ use Encode;
+ $object = JSON::XS->new->decode (decode "UTF-32LE", $jsontext);
-=head1 CONVERT WITH SINGLE QUOTES
+See to L<JSON::PP/UNICODE HANDLING ON PERLS> if the backend is PP.
-You can set a true value into $JSON::SingleQuote for JSON::Converter
-to quote any keys and values with single quotations.
-You want to parse single quoted JSON data, See L</SINGLE QUOTATION OPTION>.
+=head2 pretty
+ $json = $json->pretty([$enable])
-=head1 EXPORT
+This enables (or disables) all of the C<indent>, C<space_before> and
+C<space_after> (and in the future possibly more) flags in one call to
+generate the most readable (or most compact) form possible.
-C<objToJson>, C<jsonToObj>.

+space length.
-SingleQuote and QuotApos...
+=head2 indent
+ $json = $json->indent([$enable])
+
+ $enabled = $json->get_indent
-=head1 SEE ALSO
+If C<$enable> is true (or missing), then the C<encode> method will use a multiline
+format as output, putting every array member or object/hash key-value pair
+into its own line, identifying them properly.
-L<http://www.crockford.com/JSON/>, L<JSON::Parser>, L<JSON::Converter>

+
+ $enabled = $json->get_canonical
+
+If C<$enable> is true (or missing), then the C<encode> method will output JSON objects
+by sorting their keys. This is adding a comparatively high overhead.
+
+If C<$enable> is false, then the C<encode> method will output key-value
+pairs in the order Perl stores them (which will likely change between runs
+of the same script).
+
+This option is useful if you want the same data structure to be encoded as
+the same JSON text (given the same overall settings). If it is disabled,
+the same hash might be encoded differently even if contains the same data,
+as key-value pairs have no inherent ordering in Perl.
+
+This setting has no effect when decoding JSON texts.

+
+ $json = $json->allow_nonref([$enable])
+
+ $enabled = $json->get_allow_nonref

+If C<$enable> is true (or missing), then the C<encode> method can convert a
+non-reference into its corresponding string, number or null JSON value,
+which is an extension to RFC4627. Likewise, C<decode> will accept those JSON
+values instead of croaking.
+
+If C<$enable> is false, then the C<encode> method will croak if it isn't

+or array. Likewise, C<decode> will croak if given something that is not a

+If $enable is true (or missing), then "encode" will *not* throw an
+exception when it encounters values it cannot represent in JSON (for
+example, filehandles) but instead will encode a JSON "null" value.
+Note that blessed objects are not included here and are handled
+separately by c<allow_nonref>.
+
+If $enable is false (the default), then "encode" will throw an
+exception when it encounters anything it cannot encode as JSON.

+
+=head2 allow_blessed
+
+ $json = $json->allow_blessed([$enable])
+
+ $enabled = $json->get_allow_blessed
+
+If C<$enable> is true (or missing), then the C<encode> method will not
+barf when it encounters a blessed reference. Instead, the value of the
+B<convert_blessed> option will decide whether C<null> (C<convert_blessed>
+disabled or no C<TO_JSON> method found) or a representation of the
+object (C<convert_blessed> enabled and C<TO_JSON> method found) is being
+encoded. Has no effect on C<decode>.
+
+If C<$enable> is false (the default), then C<encode> will throw an
+exception when it encounters a blessed object.
+
+
+=head2 convert_blessed
+
+ $json = $json->convert_blessed([$enable])
+
+ $enabled = $json->get_convert_blessed
+
+If C<$enable> is true (or missing), then C<encode>, upon encountering a
+blessed object, will check for the availability of the C<TO_JSON> method
+on the object's class. If found, it will be called in scalar context
+and the resulting scalar will be encoded instead of the object. If no
+C<TO_JSON> method is found, the value of C<allow_blessed> will decide what
+to do.
+
+The C<TO_JSON> method may safely call die if it wants. If C<TO_JSON>
+returns other blessed objects, those will be handled in the same
+way. C<TO_JSON> must take care of not causing an endless recursion cycle
+(== crash) in this case. The name of C<TO_JSON> was chosen because other
+methods called by the Perl core (== not by the user of the object) are
+usually in upper case letters and to avoid collisions with the C<to_json>
+function or method.
+
+This setting does not yet influence C<decode> in any way.
+
+If C<$enable> is false, then the C<allow_blessed> setting will decide what

+ my $b_obj = B::svref_2object( $_[0] );
+ return $b_obj->isa('B::HV') ? { %{ $_[0] } }
+ : $b_obj->isa('B::AV') ? [ @{ $_[0] } ]

+
+=head2 filter_json_object
+
+ $json = $json->filter_json_object([$coderef])
+
+When C<$coderef> is specified, it will be called from C<decode> each
+time it decodes a JSON object. The only argument passed to the coderef
+is a reference to the newly-created hash. If the code references returns
+a single scalar (which need not be a reference), this value
+(i.e. a copy of that scalar to avoid aliasing) is inserted into the
+deserialised data structure. If it returns an empty list
+(NOTE: I<not> C<undef>, which is a valid scalar), the original deserialised
+hash will be inserted. This setting can slow down decoding considerably.
+
+When C<$coderef> is omitted or undefined, any existing callback will
+be removed and C<decode> will not change the deserialised hash in any
+way.
+
+Example, convert all JSON objects into the integer 5:
+ my $js = JSON->new->filter_json_object (sub { 5 });
+ # returns [5]
+ $js->decode ('[{}]'); # the given subroutine takes a hash reference.
+ # throw an exception because allow_nonref is not enabled
+ # so a lone 5 is not allowed.
+ $js->decode ('{"a":1, "b":2}');
+
+
+=head2 filter_json_single_key_object
+
+ $json = $json->filter_json_single_key_object($key [=> $coderef])
+
+Works remotely similar to C<filter_json_object>, but is only called for
+JSON objects having a single key named C<$key>.
+
+This C<$coderef> is called before the one specified via
+C<filter_json_object>, if any. It gets passed the single value in the JSON
+object. If it returns a single value, it will be inserted into the data
+structure. If it returns nothing (not even C<undef> but the empty list),
+the callback from C<filter_json_object> will be called next, as if no
+single-key callback were specified.
+
+If C<$coderef> is omitted or undefined, the corresponding callback will be
+disabled. There can only ever be one callback for a given key.
+
+As this callback gets called less often then the C<filter_json_object>
+one, decoding speed will not usually suffer as much. Therefore, single-key
+objects make excellent targets to serialise Perl objects into, especially
+as single-key JSON objects are as close to the type-tagged value concept
+as JSON gets (it's basically an ID/VALUE tuple). Of course, JSON does not
+support this in any way, so you need to make sure your data never looks
+like a serialised Perl hash.
+
+Typical names for the single object key are C<__class_whatever__>, or
+C<$__dollars_are_rarely_used__$> or C<}ugly_brace_placement>, or even
+things like C<__class_md5sum(classname)__>, to reduce the risk of clashing
+with real hashes.
+
+Example, decode JSON objects of the form C<< { "__widget__" => <id> } >>
+into the corresponding C<< $WIDGET{<id>} >> object:
+
+ # return whatever is in $WIDGET{5}:
+ JSON
+ ->new
+ ->filter_json_single_key_object (__widget__ => sub {
+ $WIDGET{ $_[0] }
+ })
+ ->decode ('{"__widget__": 5')
+
+ # this can be used with a TO_JSON method in some "widget" class
+ # for serialisation to json:
+ sub WidgetBase::TO_JSON {
+ my ($self) = @_;
+
+ unless ($self->{id}) {
+ $self->{id} = ..get..some..id..;
+ $WIDGET{$self->{id}} = $self;

+ $json = $json->shrink([$enable])
+
+ $enabled = $json->get_shrink
+
+With JSON::XS, this flag resizes strings generated by either
+C<encode> or C<decode> to their minimum size possible. This can save
+memory when your JSON texts are either very very long or you have many
+short strings. It will also try to downgrade any strings to octet-form
+if possible: perl stores strings internally either in an encoding called
+UTF-X or in octet-form. The latter cannot store everything but uses less
+space in general (and some buggy Perl or C code might even rely on that
+internal representation being used).
+
+With JSON::PP, it is noop about resizing strings but tries
+C<utf8::downgrade> to the returned string by C<encode>. See to L<utf8>.

+
+=head2 max_depth
+
+ $json = $json->max_depth([$maximum_nesting_depth])
+
+ $max_depth = $json->get_max_depth
+
+Sets the maximum nesting level (default C<512>) accepted while encoding
+or decoding. If a higher nesting level is detected in JSON text or a Perl
+data structure, then the encoder and decoder will stop and croak at that
+point.
+
+Nesting level is defined by number of hash- or arrayrefs that the encoder
+needs to traverse to reach a given point or the number of C<{> or C<[>
+characters without their matching closing parenthesis crossed to reach a
+given character in a string.
+
+If no argument is given, the highest possible setting will be used, which
+is rarely useful.
+
+Note that nesting is implemented by recursion in C. The default value has
+been chosen to be as large as typical operating systems allow without
+crashing. (JSON::XS)
+
+With JSON::PP as the backend, when a large value (100 or more) was set and
+it de/encodes a deep nested object/text, it may raise a warning
+'Deep recursion on subroutine' at the perl runtime phase.

+Set the maximum length a JSON text may have (in bytes) where decoding is

+is called on a string that is longer then this many bytes, it will not

+effect on C<encode> (yet).

+=head2 encode
+
+ $json_text = $json->encode($perl_scalar)

+converted into JSON string or number sequences, while references to arrays
+become JSON arrays and references to hashes become JSON objects. Undefined
+Perl values (e.g. C<undef>) become JSON C<null> values.
+References to the integers C<0> and C<1> are converted into C<true> and C<false>.
+
+=head2 decode

+
+JSON numbers and strings become simple Perl scalars. JSON arrays become
+Perl arrayrefs and JSON objects become Perl hashrefs. C<true> becomes

+
+=head1 INCREMENTAL PARSING
+
+Most of this section are copied and modified from L<JSON::XS/INCREMENTAL PARSING>.
+
+In some cases, there is the need for incremental parsing of JSON texts.
+This module does allow you to parse a JSON stream incrementally.
+It does so by accumulating text until it has a full JSON object, which
+it then can decode. This process is similar to using C<decode_prefix>
+to see if a full JSON object is available, but is much more efficient
+(and can be implemented with a minimum of method calls).
+
+The backend module will only attempt to parse the JSON text once it is sure it
+has enough text to get a decisive result, using a very simple but
+truly incremental parser. This means that it sometimes won't stop as
+early as the full parser, for example, it doesn't detect parenthesis
+mismatches. The only thing it guarantees is that it starts decoding as
+soon as a syntactically valid JSON text has been seen. This means you need
+to set resource limits (e.g. C<max_size>) to ensure the parser will stop
+parsing in the presence if syntax errors.
+
+The following methods implement this incremental parser.
+
+=head2 incr_parse
+
+ $json->incr_parse( [$string] ) # void context
+
+ $obj_or_undef = $json->incr_parse( [$string] ) # scalar context
+
+ @obj_or_empty = $json->incr_parse( [$string] ) # list context
+
+This is the central parsing function. It can both append new text and
+extract objects from the stream accumulated so far (both of these
+functions are optional).
+
+If C<$string> is given, then this string is appended to the already
+existing JSON fragment stored in the C<$json> object.
+
+After that, if the function is called in void context, it will simply
+return without doing anything further. This can be used to add more text
+in as many chunks as you want.
+
+If the method is called in scalar context, then it will try to extract
+exactly I<one> JSON object. If that is successful, it will return this
+object, otherwise it will return C<undef>. If there is a parse error,
+this method will croak just as C<decode> would do (one can then use
+C<incr_skip> to skip the erroneous part). This is the most common way of
+using the method.
+
+And finally, in list context, it will try to extract as many objects
+from the stream as it can find and return them, or the empty list
+otherwise. For this to work, there must be no separators between the JSON
+objects or arrays, instead they must be concatenated back-to-back. If
+an error occurs, an exception will be raised as in the scalar context
+case. Note that in this case, any previously-parsed JSON texts will be
+lost.
+
+Example: Parse some JSON arrays/objects in a given string and return them.
+
+ my @objs = JSON->new->incr_parse ("[5][7][1,2]");
+
+=head2 incr_text
+
+ $lvalue_string = $json->incr_text
+
+This method returns the currently stored JSON fragment as an lvalue, that
+is, you can manipulate it. This I<only> works when a preceding call to
+C<incr_parse> in I<scalar context> successfully returned an object. Under
+all other circumstances you must not call this function (I mean it.
+although in simple tests it might actually work, it I<will> fail under
+real world conditions). As a special exception, you can also call this
+method before having parsed anything.
+
+This function is useful in two cases: a) finding the trailing text after a
+JSON object or b) parsing multiple JSON objects separated by non-JSON text
+(such as commas).
+
+ $json->incr_text =~ s/\s*,\s*//;
+
+In Perl 5.005, C<lvalue> attribute is not available.
+You must write codes like the below:
+
+ $string = $json->incr_text;
+ $string =~ s/\s*,\s*//;
+ $json->incr_text( $string );
+
+=head2 incr_skip
+
+ $json->incr_skip
+
+This will reset the state of the incremental parser and will remove the
+parsed text from the input buffer. This is useful after C<incr_parse>
+died, in which case the input buffer and incremental parser state is left
+unchanged, to skip the text parsed so far and to reset the parse state.
+
+=head2 incr_reset
+
+ $json->incr_reset
+
+This completely resets the incremental parser, that is, after this call,
+it will be as if the parser had never parsed anything.
+
+This is useful if you want to repeatedly parse JSON objects and want to
+ignore any trailing data, which means you have to reset the parser after
+each successful decode.
+
+See to L<JSON::XS/INCREMENTAL PARSING> for examples.
+
+
+=head1 JSON::PP SUPPORT METHODS

+The below methods are JSON::PP own methods, so when C<JSON> works

+
+=head2 allow_bignum
+
+ $json = $json->allow_bignum([$enable])
+
+If C<$enable> is true (or missing), then C<decode> will convert
+the big integer Perl cannot handle as integer into a L<Math::BigInt>
+object and convert a floating number (any) into a L<Math::BigFloat>.
+
+On the contrary, C<encode> converts C<Math::BigInt> objects and C<Math::BigFloat>
+objects into JSON numbers with C<allow_blessed> enable.
+
+ $json->allow_nonref->allow_blessed->allow_bignum;
+ $bigfloat = $json->decode('2.000000000000000000000000001');
+ print $json->encode($bigfloat);
+ # => 2.000000000000000000000000001
+
+See to L<MAPPING> about the conversion of JSON number.
+
+=head2 loose
+
+ $json = $json->loose([$enable])
+
+The unescaped [\x00-\x1f\x22\x2f\x5c] strings are invalid in JSON strings
+and the module doesn't allow to C<decode> to these (except for \x2f).
+If C<$enable> is true (or missing), then C<decode> will accept these
+unescaped strings.
+
+ $json->loose->decode(qq|["abc
+ def"]|);
+
+See to L<JSON::PP/JSON::PP OWN METHODS>.
+
+=head2 escape_slash
+
+ $json = $json->escape_slash([$enable])
+
+According to JSON Grammar, I<slash> (U+002F) is escaped. But by default
+JSON backend modules encode strings without escaping slash.
+
+If C<$enable> is true (or missing), then C<encode> will escape slashes.
+
+=head2 indent_length
+
+ $json = $json->indent_length($length)
+
+With JSON::XS, The indent space length is 3 and cannot be changed.
+With JSON::PP, it sets the indent space length with the given $length.
+The default is 3. The acceptable range is 0 to 15.
+
+=head2 sort_by
+
+ $json = $json->sort_by($function_name)
+ $json = $json->sort_by($subroutine_ref)

+
+=head2 JSON -> PERL
+
+=over 4
+
+=item object
+
+A JSON object becomes a reference to a hash in Perl. No ordering of object
+keys is preserved (JSON does not preserver object key ordering itself).
+
+=item array
+
+A JSON array becomes a reference to an array in Perl.
+
+=item string
+
+A JSON string becomes a string scalar in Perl - Unicode codepoints in JSON
+are represented by the same codepoints in the Perl string, so no manual
+decoding is necessary.
+
+=item number
+
+A JSON number becomes either an integer, numeric (floating point) or
+string scalar in perl, depending on its range and any fractional parts. On
+the Perl level, there is no difference between those as Perl handles all
+the conversion details, but an integer may take slightly less memory and
+might represent more values exactly than floating point numbers.
+
+If the number consists of digits only, C<JSON> will try to represent
+it as an integer value. If that fails, it will try to represent it as
+a numeric (floating point) value if that is possible without loss of
+precision. Otherwise it will preserve the number as a string value (in
+which case you lose roundtripping ability, as the JSON number will be
+re-encoded to a JSON string).
+
+Numbers containing a fractional or exponential part will always be
+represented as numeric (floating point) values, possibly at a loss of
+precision (in which case you might lose perfect roundtripping ability, but
+the JSON number will still be re-encoded as a JSON number).
+
+Note that precision is not accuracy - binary floating point values cannot
+represent most decimal fractions exactly, and when converting from and to
+floating point, C<JSON> only guarantees precision up to but not including
+the least significant bit.
+
+If the backend is JSON::PP and C<allow_bignum> is enable, the big integers
+and the numeric can be optionally converted into L<Math::BigInt> and
+L<Math::BigFloat> objects.
+
+=item true, false
+
+These JSON atoms become C<JSON::true> and C<JSON::false>,
+respectively. They are overloaded to act almost exactly like the numbers
+C<1> and C<0>. You can check whether a scalar is a JSON boolean by using
+the C<JSON::is_bool> function.
+
+ print JSON::true + 1;
+ => 1
+
+ ok(JSON::true eq '1');
+ ok(JSON::true == 1);
+
+C<JSON> will install these missing overloading features to the backend modules.
+
+
+=item null
+
+A JSON null atom becomes C<undef> in Perl.
+
+C<JSON::null> returns C<undef>.
+
+=back
+
+
+=head2 PERL -> JSON
+
+The mapping from Perl to JSON is slightly more difficult, as Perl is a
+truly typeless language, so we can only guess which JSON type is meant by
+a Perl value.
+
+=over 4
+
+=item hash references
+
+Perl hash references become JSON objects. As there is no inherent ordering
+in hash keys (or JSON objects), they will usually be encoded in a
+pseudo-random order that can change between runs of the same program but
+stays generally the same within a single run of a program. C<JSON>
+optionally sort the hash keys (determined by the I<canonical> flag), so
+the same data structure will serialise to the same JSON text (given same
+settings and version of JSON::XS), but this incurs a runtime overhead
+and is only rarely useful, e.g. when you want to compare some JSON text
+against another for equality.
+
+In future, the ordered object feature will be added to JSON::PP using C<tie> mechanism.
+
+
+=item array references
+
+Perl array references become JSON arrays.
+
+=item other references
+
+Other unblessed references are generally not allowed and will cause an
+exception to be thrown, except for references to the integers C<0> and
+C<1>, which get turned into C<false> and C<true> atoms in JSON. You can
+also use C<JSON::false> and C<JSON::true> to improve readability.
+
+ to_json [\0,JSON::true] # yields [false,true]
+
+=item JSON::true, JSON::false, JSON::null
+
+These special values become JSON true and JSON false values,
+respectively. You can also use C<\1> and C<\0> directly if you want.
+
+JSON::null returns C<undef>.
+
+=item blessed objects
+
+Blessed objects are not directly representable in JSON. See the
+C<allow_blessed> and C<convert_blessed> methods on various options on
+how to deal with this: basically, you can choose between throwing an
+exception, encoding the reference as if it weren't blessed, or provide
+your own serialiser method.
+
+With C<convert_blessed_universally> mode, C<encode> converts blessed
+hash references or blessed array references (contains other blessed references)
+into JSON members and arrays.
+
+ use JSON -convert_blessed_universally;
+ JSON->new->allow_blessed->convert_blessed->encode( $blessed_object );
+
+See to L<convert_blessed>.
+
+=item simple scalars
+
+Simple Perl scalars (any scalar that is not a reference) are the most
+difficult objects to encode: JSON::XS and JSON::PP will encode undefined scalars as
+JSON C<null> values, scalars that have last been used in a string context
+before encoding as JSON strings, and anything else as number value:
+
+ # dump as number
+ encode_json [2] # yields [2]
+ encode_json [-3.0e17] # yields [-3e+17]
+ my $value = 5; encode_json [$value] # yields [5]
+
+ # used as string, so dump as string
+ print $value;
+ encode_json [$value] # yields ["5"]
+
+ # undef becomes null
+ encode_json [undef] # yields [null]
+
+You can force the type to be a string by stringifying it:
+
+ my $x = 3.1; # some variable containing a number
+ "$x"; # stringified
+ $x .= ""; # another, more awkward way to stringify
+ print $x; # perl does it for you, too, quite often
+
+You can force the type to be a number by numifying it:
+
+ my $x = "3"; # some variable containing a string
+ $x += 0; # numify it, ensuring it will be dumped as a number
+ $x *= 1; # same thing, the choice is yours.
+
+You can not currently force the type in other, less obscure, ways.
+
+Note that numerical precision has the same meaning as under Perl (so
+binary to decimal conversion follows the same rules as in Perl, which
+can differ to other languages). Also, your perl interpreter might expose
+extensions to the floating point numbers of your platform, such as
+infinities or NaN's - these cannot be represented in JSON, and it is an
+error to pass those in.
+
+=item Big Number
+
+If the backend is JSON::PP and C<allow_bignum> is enable,
+C<encode> converts C<Math::BigInt> objects and C<Math::BigFloat>
+objects into JSON numbers.

+=head1 JSON and ECMAscript
+
+See to L<JSON::XS/JSON and ECMAscript>.
+
+=head1 JSON and YAML
+
+JSON is not a subset of YAML.
+See to L<JSON::XS/JSON and YAML>.
+
+
+=head1 BACKEND MODULE DECISION
+
+When you use C<JSON>, C<JSON> tries to C<use> JSON::XS. If this call failed, it will
+C<uses> JSON::PP. The required JSON::XS version is I<2.2> or later.
+
+The C<JSON> constructor method returns an object inherited from the backend module,
+and JSON::XS object is a blessed scalar reference while JSON::PP is a blessed hash
+reference.
+
+So, your program should not depend on the backend module, especially
+returned objects should not be modified.
+
+ my $json = JSON->new; # XS or PP?
+ $json->{stash} = 'this is xs object'; # this code may raise an error!
+
+To check the backend module, there are some methods - C<backend>, C<is_pp> and C<is_xs>.
+
+ JSON->backend; # 'JSON::XS' or 'JSON::PP'
+
+ JSON->backend->is_pp: # 0 or 1
+
+ JSON->backend->is_xs: # 1 or 0
+
+ $json->is_xs; # 1 or 0
+
+ $json->is_pp; # 0 or 1
+
+
+If you set an environment variable C<PERL_JSON_BACKEND>, the calling action will be changed.
+
+=over
+
+=item PERL_JSON_BACKEND = 0 or PERL_JSON_BACKEND = 'JSON::PP'
+
+Always use JSON::PP
+
+=item PERL_JSON_BACKEND == 1 or PERL_JSON_BACKEND = 'JSON::XS,JSON::PP'
+
+(The default) Use compiled JSON::XS if it is properly compiled & installed,
+otherwise use JSON::PP.
+
+=item PERL_JSON_BACKEND == 2 or PERL_JSON_BACKEND = 'JSON::XS'
+
+Always use compiled JSON::XS, die if it isn't properly compiled & installed.
+
+=item PERL_JSON_BACKEND = 'JSON::backportPP'
+
+Always use JSON::backportPP.
+JSON::backportPP is JSON::PP back port module.
+C<JSON> includes JSON::backportPP instead of JSON::PP.
+
+=back
+
+These ideas come from L<DBI::PurePerl> mechanism.
+
+example:
+
+ BEGIN { $ENV{PERL_JSON_BACKEND} = 'JSON::PP' }
+ use JSON; # always uses JSON::PP
+
+In future, it may be able to specify another module.
+
+=head1 USE PP FEATURES EVEN THOUGH XS BACKEND
+
+Many methods are available with either JSON::XS or JSON::PP and
+when the backend module is JSON::XS, if any JSON::PP specific (i.e. JSON::XS unsupported)
+method is called, it will C<warn> and be noop.
+
+But If you C<use> C<JSON> passing the optional string C<-support_by_pp>,
+it makes a part of those unsupported methods available.
+This feature is achieved by using JSON::PP in C<de/encode>.
+
+ BEGIN { $ENV{PERL_JSON_BACKEND} = 2 } # with JSON::XS
+ use JSON -support_by_pp;
+ my $json = JSON->new;
+ $json->allow_nonref->escape_slash->encode("/");
+
+At this time, the returned object is a C<JSON::Backend::XS::Supportable>
+object (re-blessed XS object), and by checking JSON::XS unsupported flags
+in de/encoding, can support some unsupported methods - C<loose>, C<allow_bignum>,
+C<allow_barekey>, C<allow_singlequote>, C<escape_slash> and C<indent_length>.
+
+When any unsupported methods are not enable, C<XS de/encode> will be
+used as is. The switch is achieved by changing the symbolic tables.
+
+C<-support_by_pp> is effective only when the backend module is JSON::XS
+and it makes the de/encoding speed down a bit.
+
+See to L<JSON::PP SUPPORT METHODS>.
+
+=head1 INCOMPATIBLE CHANGES TO OLD VERSION
+
+There are big incompatibility between new version (2.00) and old (1.xx).
+If you use old C<JSON> 1.xx in your code, please check it.
+
+See to L<Transition ways from 1.xx to 2.xx.>
+
+=over
+
+=item jsonToObj and objToJson are obsoleted.
+
+Non Perl-style name C<jsonToObj> and C<objToJson> are obsoleted
+(but not yet deleted from the source).
+If you use these functions in your code, please replace them
+with C<from_json> and C<to_json>.
+
+
+=item Global variables are no longer available.
+
+C<JSON> class variables - C<$JSON::AUTOCONVERT>, C<$JSON::BareKey>, etc...
+- are not available any longer.
+Instead, various features can be used through object methods.
+
+
+=item Package JSON::Converter and JSON::Parser are deleted.
+
+Now C<JSON> bundles with JSON::PP which can handle JSON more properly than them.
+
+=item Package JSON::NotString is deleted.
+
+There was C<JSON::NotString> class which represents JSON value C<true>, C<false>, C<null>
+and numbers. It was deleted and replaced by C<JSON::Boolean>.
+
+C<JSON::Boolean> represents C<true> and C<false>.
+
+C<JSON::Boolean> does not represent C<null>.
+
+C<JSON::null> returns C<undef>.
+
+C<JSON> makes L<JSON::XS::Boolean> and L<JSON::PP::Boolean> is-a relation
+to L<JSON::Boolean>.
+
+=item function JSON::Number is obsoleted.
+
+C<JSON::Number> is now needless because JSON::XS and JSON::PP have
+round-trip integrity.
+
+=item JSONRPC modules are deleted.
+
+Perl implementation of JSON-RPC protocol - C<JSONRPC >, C<JSONRPC::Transport::HTTP>
+and C<Apache::JSONRPC > are deleted in this distribution.
+Instead of them, there is L<JSON::RPC> which supports JSON-RPC protocol version 1.1.
+
+=back
+

-
-=head1 TRANSITION PLAN
-
-In the next large update version, JSON and JSONRPC modules are split.
-
- JSONRPC* and Apache::JSONRPC are deleted from JSON dist.
- JSONRPC::Client, JSONRPC::Server and JSONRPC::Procedure in JSON::RPC dist.
-
- Modules in JSON::RPC dist supports JSONRPC protocol v1.1 and 1.0.
-
-
-=head1 DESCRIPTION
-
-This module is L<JSONRPC> subclass.
-Most ideas were borrowed from L<XMLRPC::Lite>.
-Currently C<JSONRPC> provides only CGI server function.
-
-
-=head1 CHARSET
-
-When the module returns response, its charset is UTF-8 by default.
-You can change it via passing a key/value pair into handle().
-
- my %charset = (charset => 'EUC-JP');
- JSONRPC::Transport::HTTP::CGI->dispatch_to('MyApp')->handle(%charset);
-
-=head1 QUERY OBJECT
-
-If you want to use any other query object instead of C<CGI>
-for JSONRPC::Transport::HTTP::CGI, you can pass C<query> option and
-C<paramName>.
-
- my %opt = (
- query => $session, # CGI::Session object
- paramName => 'json',
- );
-
- JSONRPC::Transport::HTTP::CGI->dispatch_to('MyApp')->handle(%opt);
-
-
-=head1 CAUTION
-
-JSONRPC::Transport::HTTP::CGI requires CGI.pm which version is more than 2.9.2.
-(the core module in Perl 5.8.1.)
-
-
-Since verion 1.0, JSONRPC::Transport::HTTP requires L<HTTP::Request>
-and L<HTTP::Response>. For using JSONRPC::Transport::HTTP::Client,
-you need L<LWP::UserAgent>.
