-# Devcontainer (development environment in the cloud) for GDevelop (beta)
-
-A devcontainer is the configuration to run a cloud development environment, available remotely.
-This is notably used to run a **[GitHub Codespace](https://docs.github.com/en/github/developing-online-with-codespaces/about-codespaces)**. The advantage is that you can quickly experiment and do changes without installing anything on your computer.
-
-> ⚠️ This development environment is in beta, and not everything is supported. This is useful for playing a bit with GDevelop codebase or to make quick changes. **In particular, it's not possible to test your changes on GDJS** because only the web-app can be launched.
-
-It's recommended that you follow the usual [README](../newIDE/README.md) to get started, with development tools installed on your computer.
-
-## Start a GitHub workspace to work on GDevelop (beta)
-
-- Subscribe to the [beta edition of GitHub workspace](https://docs.github.com/en/github/developing-online-with-codespaces/about-codespaces#joining-the-beta).
-- In the repository GitHub page, click **Code** and then choose **Open with Codespaces**.
-- Wait for the Codespace to load and Visual Studio Code to open.
-- When it's ready, open a terminal in Visual Studio Code.
-- Follow the usual [README in `newIDE`](../newIDE/README.md) to get started, like you would do on your own computer.

  *
- * The **GDevelop Core** library contains the structure of a GDevelop game, classes and tools that are used by the *platforms* and the *GDevelop IDE*.
+ * The **GDevelop Core** library contains the main concepts, classes and tools that are used by the *platforms* and the *GDevelop IDE*.<br>
+ * This ensures that the IDE, or any tool based on GDevelop Core, is able to work with projects based on any arbitrary platform.
+ *
+ * Two official platforms are available for GDevelop:
+ *  - The *C++ Platform* (GDCpp) to create native games.
+ *  - The *JS Platform* (GDJS) to create HTML5 games.
  *
  * \section gettingstarted Getting started
+ * First, please refer to these pages to install the required tools and to get help about setting up a basic extension:<br>
  *
- * In most cases, you should start by <a href="https://github.com/4ian/GDevelop/blob/master/newIDE/README.md">installing and launching the development version of GDevelop</a>.
+ * -# \subpage setupDevEnv
+ * -# \ref overview
+ * -# \ref writeANewExtension
  *
- * - If you're interested in writing extensions for GDevelop, read <a href="https://github.com/4ian/GDevelop/blob/master/newIDE/README-extensions.md">the documentation about extensions</a>.
- * - If you want to dig more into how GDevelop is architectured and work on the core, read <a href="https://github.com/4ian/GDevelop/blob/master/Core/GDevelop-Architecture-Overview.md">GDevelop Architecture Overview</a>. Then, you can browse this reference to get more information about a class or function.
+ * You can also read \subpage recommendedToolsAndConventions.
  *
- * \section other Other documentations
+ * \section aboutdoc About this documentation
  *
- * GDevelop is architectured around a `Core` (this library), a game engine (`GDJS`) and extensions (`Extensions` folder). The editor (`newIDE` folder) is using all of these libraries.
+ * If you never used GDevelop Core before, take a look at \ref overview.
  *
+ * As everything that is developed around GDevelop is based on this library, you should take a look at it quite often: platforms, extensions
+ * and the IDE are intensively using the classes and tools offered by GDCore.
+ * When developing an extension for the C++ or JS platform, read these documentations:
+ *
+ *  - [Open GDevelop C++ Platform documentation](../GDCpp Documentation/index.html)
  *  - [Open GDevelop JS Platform documentation](../GDJS Documentation/index.html)
- *  - <a href="https://github.com/4ian/GDevelop/blob/master/newIDE/README.md">Getting started with the editor</a>
- *  - <a href="https://github.com/4ian/GDevelop/blob/master/newIDE/README-extensions.md">Getting started with the extensions</a>

+/**
+ *  \page installWinCompiler (Windows) Install TDM-GCC compiler
+ *
+ * GDevelop is compiled with TDM-GCC under Windows.<br>
+ * So as to prevent incompatibilities between the compiler (and the standard C++ library provided with) used by GDevelop and
+ * the compiler used by the extensions, GDevelop require the extensions and the platforms to use the same version of TDM-GCC.
+ *
+ * While a recent GCC version should work, if you compile GDevelop for an "official" distribution it's better
+ * to use the specific version provided here.
+ *
+ * \section installWinCompiler_download Download
+ *
+ * Download the current version of the compiler used by GDevelop on Windows here:

+
+ \image html compilerInstall1.png
+
+ * - Choose an installation directory.<br>

+
+/**
+ *  \page installAndUseCMake (All) Install CMake & launch the build
+ *
+ * Building is done using CMake: it is an open-source build system that can generate build files for lots of IDE and build tools (Makefiles...).
+ *
+ * \section installAndUseCMake_download Download and install CMake
+ *
+ * First, install CMake:
+ * Download it [here](http://www.cmake.org/cmake/resources/software.html) for Windows, get it using your package manager if you're
+ * using a Linux distribution or using Homebrew for Mac OS X.
+ *
+ * \section installAndUseCMake_use Using CMake to generate the build files
+ * Using CMake is not difficult and require only a few clicks/commands to enter. Windows users may use
+ * the GUI as shown in the next section. Linux and Mac OS X users may prefer to use the command line as shown
+ * as the end of this page.
+ *
+ * \subsection installAndUseCMake_use_gui Using the GUI
+ *
+ * - Start the CMake user interface (_cmake-gui_). Choose the GD root directory as the source directory, and Binaries/build as the directory where to build the binaries:
+
+ \image html usecmake1.png
+
+ * - Click on *Configure*. If asked to create the build directory, answer yes. Choose then your favorite generator: *MinGW Makefiles* (on Windows) or *Unix Makefiles* (on Linux/OS X) generate a traditional Makefile that can be built using the
+ * *mingw32-make* (on Windows) or *make* (on Linux/OS X) command. You can also choose the *Ninja* generator to use the [Ninja build system](http://martine.github.io/ninja/).
+
+  \image html usecmake2.png
+
+ * - When you click on Finish, CMake do a first configuration. If **errors occurred*, make sure that you have download all required development libraries.
+ * - Adjust any variable if necessary (no changes is needed by default), then click on Generate.
+
+  \image html usecmake3.png
+
+ * - You can then launch a terminal/command prompt, go to the build folder (`cd path/to/GD/Binaries/build`) and launch the build
+ * using the generator you've choosen: `mingw32-make`, or `make` on Linux/OS X.
+ *
+ * \subsection installAndUseCMake_use_cmd Using the command line
+ *
+ * Using the commandline with CMake is also easy:
+ *
+ * ~~~~~~~~~~~~~~~~~~~~~
+ * cd /path/to/GD/Binaries
+ * mkdir build
+ * cd build
+ * cmake ../..
+ * make
+ * ~~~~~~~~~~~~~~~~~~~~~
+ *
+ * For Windows, replace `cmake ../..` by `cmake ../.. -G "MinGW Makefiles"` and `make` by `mingw32-make`.
+ *
+ * or using the fast [Ninja build system](http://martine.github.io/ninja/) :
+ * ~~~~~~~~~~~~~~~~~~~~~
+ * cd /path/to/GD/Binaries
+ * mkdir build
+ * cd build
+ * cmake ../.. -G "Ninja"
+ * ninja
+ * ~~~~~~~~~~~~~~~~~~~~~
+ *
+ * \section installAndUseCMake_launch Launch GDevelop
+ *
+ * Binaries are created into *Binaries/Output/Release_{OS}* folder.
+ *
+ * To launch GDevelop in Windows, double click on **GDIDE**. For Linux, launch **StartGDevelop.sh**.

+/**
+ * \page overview Overview of GDCore
+ *
+ * \section platformstructure Structure of a platform
+ *
+ * A platform for GDevelop Core is a class inheriting from gd::Platform.<br>
+ * They contains the extensions of the platform (see below) and offer various methods, like gd::Platform::GetProjectExporters which
+ * is called by the IDE to export a gd::Project to a stand-alone game.
+ *
+ * \subsection platformloading Platforms loading
+ * A platform is stored in memory and managed by gd::PlatformManager. It loaded from a dynamic library file (.dll on windows, .so on Linux)
+ * thanks to gd::PlatformLoader.<br>
+ * It is responsibility of the IDE, or any other application using GDCore,
+ * to call the appropriate method of gd::PlatformLoader to trigger the loading of the platforms when needed.
+ *
+ * gd::PlatformLoader search for two symbols in the dynamic library file: *CreateGDPlatform* and
+ * *DestroyGDPlatform*. These symbols must exists and must create (or destroy) the platform class. For example:
+ *
+ * ~~~~~~~~~~~~~~~~~~~~~
+ * extern "C" gd::Platform * GD_API CreateGDPlatform() {
+ *     return &JsPlatform::Get(); //Return the singleton object representing the JS Platform
+ * }
+ *
+ * extern "C" void GD_API DestroyGDPlatform() {
+ *     JsPlatform::DestroySingleton(); //Destroy the singleton.
+ * }
+ * ~~~~~~~~~~~~~~~~~~~~~
+ *
+ * The platform dynamic library file is often located inside <i>GDevelop directory</i>/xxxPlatform (*xxx* being replaced by the platform acronym).
+ *
+ * In this folder, the platform can store basically anything it needs. For example, both GDJS and GDCpp are storing a folder called *Runtime* containing
+ * the game engine.
+ * If there is a sub directory called *Extensions*, the gd::PlatformLoader tries to load the extensions contained inside (see below).
+ *
+ * \section extensionsstructure Structure of an extension
+ *
+ * **Extensions** are seen by GDevelop Core as classes inheriting from gd::PlatformExtension.<br>
+ * They are stored inside the platform they belong to, and they are also loaded from a dynamic library file thanks to gd::ExtensionsLoader. The main
+ * job of an extension is to <b>declare</b> everything it provides: objects, actions and conditions, behaviors, expressions.<br>
+ * This is done directly using the standard method provided by gd::PlatformExtension, notably:
+ *  - gd::PlatformExtension::AddCondition and gd::PlatformExtension::AddAction,
+ *  - gd::PlatformExtension::AddExpression (and gd::PlatformExtension::AddStrExpression),
+ *  - gd::PlatformExtension::AddObject and gd::PlatformExtension::AddBehavior
+ *
+ *
+ * Some platforms (like the C++ Platform) offer another base class which must be used instead of gd::PlatformExtension when declaring a platorm: as this base class
+ * inherits from gd::PlatformExtension, standard methods still work, but you may be able to declare some others features (the C++ Platform offers
+ * the possibility of declaring debugger related functions).
+ *
+ * \subsection extensionloading Extensions loading
+ *
+ * A single dynamic library file can contains an extension for more than one platform:<br>
+ * You just have to declare a class deriving from gd::PlatformExtension for each platform supported, and a creation function for each platform
+ * (the C++ platform expects a function called *CreateGDExtension* while JS Platform search for a function called *CreateGDJSExtension*).
+ *
+ * \subsection extensionexample Edit or write a new extension
+ *
+ * Refer to these pages for more information about extensions:
+ *  - \subpage AboutExtensionCpp
+ *  - \subpage writeANewExtension
+ *
+ * \section utf8section UTF8 strings
+ *
+ * Most parts of the codebase support UTF8 strings thanks to gd::String class. gd::String is a wrapper around std::string, exposing a similar
+ * interface as well as a few tool member functions and operators that are all UTF8 aware.
+ *
+ * Its usage is easy, especially if you're familiar with std::string. Some extra functions can be really useful, in particular
+ * the ones to convert the string from/to a number.
+ *
+ \code
+gd::String str = "Hello";
+str += " world";
+str += " " + gd::String::From(2);
+//str now contains "Hello world 2";
+
+gd::String twopointfiveStr = "2.5";
+double twopointfive = twopointfive.To<double>();
+//twopointfive == 2.5
+ \endcode
+ *
+ *
+ * For more information, see the complete reference of the class. Tests cases have also been made for most functions.
+ */
+
+/**
+ * \page writeANewExtension Write a new extension
+ *
+ * \section writeANewExtension_createNewExtension Create a new extension
+ *
+ * Creation of a new extension can be made by following these steps:<br>
+ *
+ * - Copy the directory of an extension and rename it:
+ * \image html createnew1.png
+ * - Rename then the sources files :
+ * \image html createnew2.png
+ * - Open the *CMakeLists.txt* file and replace every occurrence of the extension old name with the new name.<br>
+ * - Open all the source files and again, replace every occurrence of the extension old name with the new name.<br>
+ * - In the *Extensions* directory, open the *CMakeLists.txt* file and add a line such as <code>ADD_SUBDIRECTORY(MyExtension)</code>.
+ * You can then start to modify the extension.<br>
+ * If your extension is fairly simple, you can create it from the AES Extension. <br>
+ * If your extension need an object, you can use for instance the TextObject Extension as a starting point.<br>
+ * <br>
+ * - You can compile your extension by relaunching CMake like described [here](\ref installAndUseCMake). After doing that, just compile as usual.
+ *
+ */
+
+/**
+ * \page AboutExtensionCpp About Extension.cpp
+ *
+ * An extension has to define (usually in a file called *Extension.cpp* for the C++ Platform or *JsExtension.cpp* for the JS Platform)
+ * a class that is derived from the gd::PlatformExtension class. This class contains, in its constructor, the declarations
+ * of everything that is provided by the extension.
+
+ * \section extensionDeclaration Declare the extension information
+
+ * The declarations are made using the methods provided by gd::PlatformExtension.
+ *
+ * The first declaration if often the information about the extension:
+
+ * \code
+    Extension()
+    {
+            SetExtensionInformation("TextObject",
+                                  _("Text object"),
+                                  _("Extension allowing to use an object displaying a text."),
+                                  "Florian Rival",
+                                  "Open Source (MIT License)");
+ * \endcode
+
+The first parameter is the name of the extension. Choose carefully the name of the extension, as projects are directly referring to it.
+
+ * \section instructionsDeclaration Declare actions, conditions and expressions
+
+Actions are declared like this :
+
+ * \code
+            AddAction("ActionName",
+                           _("Name displayed to users"),
+                           _("Description"),
+                           _("Sentence displayed in event editor"),
+                           _("Category"),
+                           "path-to-an-24-by-24-icon-file.png",
+                           "path-to-an-16-by-16-icon-file.png")
+                .AddParameter("theTypeOfTheParameter", _("Parameter1"))
+                .AddParameter("theTypeOfTheParameter", _("Parameter2"))
+                .SetFunctionName("MyFunctionName").SetIncludeFile("MyExtension/MyIncludeFile.h");
+
+ * \endcode
+ * Declare conditions and expressions in a similar way.<br>
+ * Parameters are added using gd::InstructionMetadata::AddParameter.
+ *
+ * The last line set the function name that will be called when generating the code of an event using the action:<br>
+ * You can either do it after declaring the function, or later using this syntax:
+ *
+ * \code
+        GetAllActions()["ExtensionName::ActionName"].SetFunctionName("MyFunctionName");
+ * \endcode
+ *
+ * Both methods are ok, but the latest allows to use the same code to declare an extension for the C++ and JS platform,
+ * then customize the names of the functions to call.
+ *
+ * \section objectsDeclaration Declare objects
+ *
+ * Adding an object is made using gd::PlatformExtension::AddObject method.
+ *
+ * \code
+        gd::ObjectMetadata & obj = AddObject<MyObject>(
+                           "Name",
+                           _("Name displayed to users"),
+                           _("Description"),
+                           "path-to-a-32-by-32-icon.png");
+ * \endcode
+ *
+ * The *C++ platform* also requires that you call *AddRuntimeObject* to declare the RuntimeObject class associated to the object being declared:<br>
+ * It has two template parameters: the first one is the corresponding object class declared with *AddObject* (class inheriting from *gd::Object*) and the
+ * second one is the *RuntimeObject* class.
+ * You must pass as parameter the metadata from the object previously declared and the name of the class inheriting from RuntimeObject.
+ *
+ * You will also want to specify the .h file associated to the object using gd::ObjectMetadata::SetIncludeFile. For example:
+ * \code
+//obj is the gd::ObjectMetadata returned when you called AddObject.
+AddRuntimeObject<TextObject, RuntimeTextObject>(obj, "RuntimeTextObject");
+obj.SetIncludeFile("TextObject/TextObject.h");
+ * \endcode
+ *
+ * You can then declare the actions, conditions, and expressions related to the objects, using the AddAction/AddCondition/AddExpression methods provided
+ * by <i>obj</i>.
+
+ * \section eventsDeclaration Declaring events
+ *
+ * Events are declared like this :
+ * \code
+AddEvent("Name",
+         _("Name displayed to users"),
+         "Description",
+         "Group",
+         "path-to-a-16-by-16-icon.png",
+         std::make_shared<EventClassName>())
+ * \endcode
+ *
+ * The event must be able to generate its code when events are being translated to C++ or Javascript:<br>
+ * This is done by calling SetCodeGenerator. For example:
+ *
+ * \code
+AddEvent("Standard",
+         _("Standard event"),
+         _("Standard event: Actions are run if conditions are fulfilled."),
+         "",
+         "res/eventaddicon.png",
+         std::make_shared<gd::StandardEvent>())
+	.SetCodeGenerator(std::shared_ptr<gd::EventMetadata::CodeGenerator>(codeGen));
+ * \endcode
+
+ * \section behaviorsDeclaration Declaring the behaviors
+
+Behaviors are declared like objects:
+
+
+ * \code
+gd::BehaviorMetadata & aut = AddBehavior("Name",
+	_("Name displayed to users"),
+	_("DefaultNameUsedInEditor"),
+	_("Description."),
+	"Group",
+	"path-to-a-32-by-32-icon.png",
+	"BehaviorClassName",
+	std::make_shared<BehaviorClassName>(),
+	std::make_shared<BehaviorSharedDataClassName>());
+ * \endcode
+ * The last line can be replaced by <code>std::shared_ptr<gd::BehaviorsSharedData>()</code> if no shared data are being used.
+ *
+ * You can then declare the actions, conditions, and expressions related to the behavior like objects:<br>
+ * Call AddAction/AddCondition/AddExpression on the <i>aut</i> object.
+
+ * \section excludingNonRuntimeDeclaration (C++ platform) Excluding elements declaration from runtime
+ * When your extension is compiled for the C++ platform Runtime, GDevelop does not known anything about action/condition or even events classes.<br>
+ * You have then to exclude all actions/conditions/expressions/events declaration from extension at runtime (only Extension/Object/Behaviors declarations have to be kept).
+
+ * Use the *<code>GD_IDE_ONLY</code> define* to achieve this goal, as demonstrated in this skeleton of a complete extension declaration:
+ * \code
+class Extension : public ExtensionBase //For C++ platform, extensions must derive from ExtensionBase
+{
+public:
+    Extension()
+    {
+        SetExtensionInformation("MyExtension",
+                              _("Extension name"),
+                              _("Extension declaration"),
+                              "Author",
+                              "license");
+
+        #if defined(GD_IDE_ONLY)
+        AddAction(...);
+        AddCondition(...);
+        AddExpression(...);
+        #endif
