Free json software for linux

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. Json-lib is easy for machines to parse and generate.
It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others.
These properties make JSON an ideal data-interchange language. This library is based on the work by Douglas Crockford in http://www.json.org/java , adding support for java arrays and object graphs. With this library it is possible to transform the following java structures to JSON: java beans, java arrays, collections, maps; composites of the 4 previous types.
The main driver for this library is to provide the means to transform data between a server and an AJAX enabled application.
Enhancements:
- This release includes major enhancements like custom serialization, Groovy/JRuby support, cycle detection. and better XML two-way serialization.

JSON::PC is a fast JSON parser and converter.

SYNOPSIS

use JSON::PC;

my $json = new JSON::PC;

my $obj = $json->parse(q/{foo => [1,2,3], bar => "perl"}/);

print $json->convert($obj);

# or

$obj = JSON::PC::parse(q/{foo => [1,2,3], bar => "perl"}/);
print JSON::PC::convert($obj);

METHODS

Except new method, all methods are object method.

new()

new(%option)

This is a class method and returns new JSON::PC object.

parse($str)

parse($str, $options_ref)

takes JSON foramt string and returns perl data structure. jsonToObj is an alias.

convert($obj)

convert($obj, $options_ref)

takes perl data structure and returns JSON foramt string. objToJson is an alias.

autoconv($int)

This is an accessor to autoconv. See "AUTOCONVERT" for more info.

skipinvalid($int)

convert() does die() when it encounters any invalid data (for instance, coderefs). If skipinvalid is set with true(integer), the function convets these invalid data into JSON formats null.

execcoderef($int)

convert() does die() when it encounters any code reference. However, if execcoderef is set with true(integer), executes the coderef and uses returned value.

pretty($int)

This is an accessor to pretty. When prrety is true(integer), objToJson() returns prrety-printed string. See "PRETTY PRINTING" for more info.

indent($int)

This is an accessor to indent. See "PRETTY PRINTING" for more info.

delimiter($int)

This is an accessor to delimiter. See "PRETTY PRINTING" for more info.

unmapping($int)

This is an accessor to unmapping. See "UNMAPPING OPTION" for more info.

keysort($int)

keysort($code_ref)

This is an accessor to keysort. See "HASH KEY SORT ORDER" for more info.

convblessed($int)

This is an accessor to convblessed. See "BLESSED OBJECT" for more info.

selfconvert($int)

This is an accessor to selfconvert. See "BLESSED OBJECT" for more info.

singlequote($int)

This is an accessor to singlequote. See "CONVERT WITH SINGLE QUOTES" for more info.

barekey($int)

You can set a true(integer) to parse bare keys of objects.

quotapos($int)

You can set a true(integer) to parse any keys and values quoted by single quotations.

utf8($int)

This is an accessor to utf8. You can set a true(integer) to set UTF8 flag into strings contain utf8.

JSON::Shell is an interactive shell for performing JSON and JSON-RPC requests.

SYNOPSIS

$ bin/jsonshell

JSON::Shell 1.0
www.example.com/json-rpc-demo$ post { "id": 1, "method": "echoObject", "params": { "o": [ "YAY JSON~" ] } }
REQUEST: $VAR1 = {
params => {
o => [
YAY JSON~
]
},
method => echoObject,
id => 1
};

RESPONSE: $VAR1 = {
id => 1,
result => [
YAY JSON~
]
};

JSON::Shell provides an interactive debugger and workbench for JSON based web services.

JSON::Syck - JSON is YAML.

SYNOPSIS

use JSON::Syck;

my $data = JSON::Syck::Load($json);
my $json = JSON::Syck::Dump($data);

JSON::Syck is a syck implementatoin of JSON parsing and generation. Because JSON is YAML (http://redhanded.hobix.com/inspect/yamlIsJson.html), using syck gives you the fastest and most memory efficient parser and dumper for JSON data representation.

DIFFERENCE WITH JSON

You might want to know the difference between JSON and JSON::Syck.

Since JSON is a pure-perl module and JSON::Syck is based on libsyck, JSON::Syck is supposed to be very fast and memory efficient. See chansens benchmark table at http://idisk.mac.com/christian.hansen/Public/perl/serialize.pl
JSON.pm comes with dozens of ways to do the same thing and lots of options, while JSON::Syck doesnt. Theres only Load and Dump.

Oh, and JSON::Syck doesnt use camelCase method names.

JSON-RPC-Java provides an RPC implementation that allows JavaScript DHTML Web applications to call remote methods in a Java Application Server (AJAX functionality) without the need for page reloading.
JSON-RPC-Java library is an enabler for the next generation of fast and highly dynamic enterprise Java Web applications. Minimal changes (if any) are necessary to existing server-side Java code to allow calling from JavaScript (such as the marshalling and unmarshalling of special types), as JSON-RPC-Java dynamically maps JavaScript objects to and from Java objects using Java reflection.
Enhancements:
- The license has changed from the LGPL to the Apache License, Version 2.0.
- New object registration, lookup, and unregister APIs have been added to JSONRPCBridge.

Config::JSON is a JSON based config file system.

SYNOPSIS

use Config::JSON;

my $config = Config::JSON->create($pathToFile);
my $config = Config::JSON->new($pathToFile);

my $element = $config->get($param);

$config->set($param,$value);

$config->delete($param);
$config->deleteFromHash($name, $key);
$config->deleteFromArray($name, $value);

$config->addToHash($name, $key, $value);
$config->addToArray($name, $value);

my $path = $config->getFilename;
Example Config File
# config-file-type: JSON 1

{
"dsn" : "DBI:mysql:test",
"user" : "tester",
"password" : "xxxxxx",

# some colors to choose from
"colors" : [ "red", "green", "blue" ],

# some statistics
"stats" : {
"health" : 32,
"vitality" : 11
}
}

Note that you can put comments in the config file as long as # is the first non-space character on the line. However, if you use this API to write to the config file, your comments will be eliminated.

Apache2::JSONRPC is a mod_perl handler for JSONRPC.

SYNOPSIS

< Location /json-rpc >
SetHandler perl-script
PerlOptions +GlobalRequest
PerlResponseHandler Apache2::JSONRPC->handler
JSONRPC_Class CGI::JSONRPC::Dispatcher
< /Location >

Apache2::JSONRPC is a subclass of CGI::JSONRPC that provides some extra bells and whistles in a mod_perl2 environment.
Currently, the main feature is the "JSONRPC_Class" apache2 config directive, which allows you to define what class to use for invoking JSONRPC methods. The default is the same as CGI::JSONRPC uses, CGI::JSONRPC::Dispatcher.

JCameo project is a model-driven Swing framework with support for all aspects of GUI development. Key features are a large number of widgets, MVC architecture, data binding, and validation support, as well as message-based communication. It requires Java 1.5.

Whats New in This Release:

* The MDE package which implements the model-driven view construction was
completely rewritten. The goal of this work is to ease the development of tool
support for JCameo.
The main change is the use of an explicit schema for the types used to
describe the view. The schema itself has a JSON-like notation.
* CcMessageListener now invokes listener code always on the EDT.
* NEW widget CheckBoxMenuItem
* Action
- Actions with attributes refid are now a type on their own, so
has to be transformed into
* CheckBox
- new property selected for setting the initial selection state
* Grid
- new property background for setting the background color.
* Hbox
- new property background for setting the background color.
* Vbox
- new property background for setting the background color.
* TitledPanel
- new property titlePainter for setting the painter used to paint
the header. Accepts one of: AERITH, BLUE_EXPERIENCE, GRAY, NIGHT_GRAY,
NIGHT_GRAY_LIGHT, and RED_XP.
* new JCTreeModel which can be configured to edit a given property of the user
object.
* added CardPane demo

Third party upgrades

* upgrade to SwingX 20070527
* upgrade to spring 2.0.5
