PHP Lua Serializer/Deserializer

This is a very simple Lua serializer/deserializer for PHP, with support for JMS Serializer.

Installation

Install with Composer:

composer require koesie10/lua-serializer

Usage

There is a facade for both serialization and deserialization:

$result = \Vlaswinkel\Lua\Lua::serialize([ 'foo' => 'bar']);
/**
 * Returns:
 * {
 *      foo = "bar",
 * }
 */
 
$result = \Vlaswinkel\Lua\Lua::deserialize('{ foo = "bar" }')
/**
 * Returns:
 * [ 'foo' => 'bar' ]
 */

You can also use all the classes yourself:

$result = \Vlaswinkel\Lua\Serializer::encode([ 'foo' => 'bar' ]); // returns the same as above

$parser = new \Vlaswinkel\Lua\Parser(new \Vlaswinkel\Lua\TokenStream(new \Vlaswinkel\Lua\InputStream('{ foo = "bar" }')));
$result = \Vlaswinkel\Lua\LuaToPhpConverter::convertToPhpValue($parser->parse()); // returns the same as above

Integration with JMS Serializer in Symfony2

This serializer can easily be included into Symfony2 with JMSSerializer, by adding the following lines to your services.yml:

services:
    app.lua.serialization_visitor:
        class: Vlaswinkel\Lua\JMS\LuaSerializationVisitor
        arguments: ["@jms_serializer.naming_strategy"]
        tags:
            - { name: jms_serializer.serialization_visitor, format: lua }
    app.lua.deserialization_visitor:
        class: Vlaswinkel\Lua\JMS\LuaDeserializationVisitor
        arguments: ["@jms_serializer.naming_strategy"]
        tags:
            - { name: jms_serializer.deserialization_visitor, format: lua }
    app.lua.array_handler:
        class: Vlaswinkel\Lua\JMS\LuaArrayCollectionHandler
        tags:
            - { name: jms_serializer.subscribing_handler }
    app.lua.date_handler:
        class: Vlaswinkel\Lua\JMS\LuaDateHandler
        tags:
            - { name: jms_serializer.subscribing_handler }
    app.lua_constraint_violation_handler:
        class: Vlaswinkel\Lua\JMS\LuaConstraintViolationHandler
        tags:
            - { name: jms_serializer.subscribing_handler }
    app.lua.form_handler:
        class: Vlaswinkel\Lua\JMS\LuaFormHandler
        arguments: ["@translator"]
        tags:
            - { name: jms_serializer.subscribing_handler }
    app.lua_php_collection_handler:
        class: Vlaswinkel\Lua\JMS\LuaPhpCollectionHandler
        tags:
            - { name: jms_serializer.subscribing_handler }

If you want Symfony to recognize Lua as a request/response format, also add the following to your config.yml:

framework:
    request:
        formats:
            lua: ['application/x-lua', 'application/lua']

In this case I've added application/x-lua and application/lua as MIME-types, but as there's no standard for Lua content types, these can be whatever you like.

You can now use the format lua for serialization:

public function indexAction() {
    return $this->get('serializer')->serialize([ 'foo' => 'bar' ], 'lua');
}

Running tests

You can run automated unit tests using PHPUnit after installing dependencies:
