* @title: GApplication
* @short_description: Core application class
*
* A #GApplication is the foundation of an application, unique for a
- * given application identifier. The #GApplication wraps some
+ * given application identifier. The GApplication class wraps some
* low-level platform-specific services and is intended to act as the
* foundation for higher-level application classes such as
* #GtkApplication or #MxApplication. In general, you should not use
- * this class outside of a higher level framework. By default,
- * g_application_register_with_data() will invoke g_error() if it is
- * run in a context where it cannot support its core features. Note
- * that g_error() is by default fatal.
+ * this class outside of a higher level framework.
*
- * One of the core features that #GApplication provides is process
+ * One of the core features that GApplication provides is process
* uniqueness, in the context of a "session". The session concept is
* platform-dependent, but corresponds roughly to a graphical desktop
* login. When your application is launched again, its arguments
* are passed through platform communication to the already running
- * program.
- *
- * In addition, #GApplication provides support for 'actions', which
- * can be presented to the user in a platform-specific way
- * (e.g. Windows 7 jump lists). Note that these are just simple
- * actions without parameters. For more flexible scriptability,
- * implementing a a separate D-Bus interface is recommended, see e.g.
- * <xref linkend="gdbus-convenience"/>.
- *
- * Finally, #GApplication acts as a basic lifecycle root; see the
- * g_application_run() and g_application_quit_with_data() methods.
- *
- * Before using #GApplication, you must choose an "application identifier".
+ * program. The already running instance of the program is called the
+ * <firstterm>primary instance</firstterm>.
+ *
+ * Before using GApplication, you must choose an "application identifier".
* The expected form of an application identifier is very close to that of
* of a <ulink url="http://dbus.freedesktop.org/doc/dbus-specification.html#message-protocol-names-interface">DBus bus name</ulink>.
- * Examples include: "com.example.MyApp" "org.example.internal-apps.Calculator"
- * For convenience, the restrictions on application identifiers are reproduced
- * here:
+ * Examples include: "com.example.MyApp", "org.example.internal-apps.Calculator".
+ * For details on valid application identifiers, see
+ * g_application_id_is_valid().
+ *
+ * The application identifier is claimed by the application as a
+ * well-known bus name on the user's session bus. This means that the
+ * uniqueness of your application is scoped to the current session. It
+ * also means that your application may provide additional services
+ * (through registration of other object paths) at that bus name.
+ *
+ * The registration of these object paths should be done with the shared
+ * GDBus session bus. Note that due to the internal architecture of
+ * GDBus, method calls can be dispatched at any time (even if a main
+ * loop is not running). For this reason, you must ensure that any
+ * object paths that you wish to register are registered before
+ * #GApplication attempts to acquire the bus name of your application
+ * (which happens in g_application_register()). Unfortunately, this
+ * means that you cannot use g_application_get_is_remote() to decide if
+ * you want to register object paths.
+ *
+ * GApplication provides convenient life cycle management by maintaining
+ * a <firstterm>use count</firstterm> for the primary application instance.
+ * The use count can be changed using g_application_hold() and
+ * g_application_release(). If it drops to zero, the application exits.
+ *
+ * GApplication also implements the #GActionGroup interface and lets you
+ * easily export actions by adding them with g_application_set_action_group().
+ * When invoking an action by calling g_action_group_activate_action() on
+ * the application, it is always invoked in the primary instance. The actions
+ * are also exported on the session bus, and GIO provides the #GDBusActionGroup
+ * wrapper to conveniently access them remotely. Additionally,
+ * g_application_set_menu() can be used to export representation data
+ * for the actions, in the form of a #GMenuModel.
+ *
+ * There is a number of different entry points into a #GApplication:
* <itemizedlist>
- * <listitem>Application identifiers must contain only the ASCII characters "[A-Z][a-z][0-9]_-" and must not begin with a digit.</listitem>
- * <listitem>Application identifiers must contain at least one '.' (period) character (and thus at least two elements).</listitem>
- * <listitem>Application identifiers must not begin with a '.' (period) character.</listitem>
- * <listitem>Application identifiers must not exceed 255 characters.</listitem>
+ * <listitem>via 'Activate' (i.e. just starting the application)</listitem>
+ * <listitem>via 'Open' (i.e. opening some files)</listitem>
+ * <listitem>by handling a command-line</listitem>
+ * <listitem>via activating an action</listitem>
* </itemizedlist>
- *
- * <refsect2><title>D-Bus implementation</title>
- * <para>
- * On UNIX systems using D-Bus, #GApplication is implemented by claiming the
- * application identifier as a bus name on the session bus. The implementation
- * exports an object at the object path that is created by replacing '.' with
- * '/' in the application identifier (e.g. the object path for the
- * application id 'org.gtk.TestApp' is '/org/gtk/TestApp'). The object
- * implements the org.gtk.Application interface.

- * <para>
- * The <methodname>Activate</methodname> function is called on the existing
- * application instance when a second instance fails to take the bus name.
- * @arguments contains the commandline arguments given to the second instance
- * and @data contains platform-specific additional data.
- *
- * On all platforms, @data will have a key "cwd" of type signature
- * "ay" which contains the working directory of the invoked
- * executable; this data is defined to be in the default GLib
- * filesystem encoding for the platform. See g_filename_to_utf8().
- *
- * </para>
- * <para>
- * The <methodname>InvokeAction</methodname> function can be called to
- * invoke one of the actions exported by the application. On X11
- * platforms, the platform_data argument should have a "timestamp"
- * parameter of type "u" with the server time of the initiating event.
- * </para>
- * <para>
- * The <methodname>ListActions</methodname> function returns a dictionary
- * with the exported actions of the application. The keys of the dictionary
- * are the action names, and the values are structs containing the description
- * for the action and a boolean that represents if the action is enabled or not.
- * </para>
- * <para>
- * The <methodname>Quit</methodname> function can be called to
- * terminate the application. The @data parameter contains
- * platform-specific data. On X11 platforms, the platform_data
- * argument should have a "timestamp" parameter of type "u" with the
- * server time of the initiating event.
- * </para>
- * <para>
- * The <methodname>ActionsChanged</methodname> signal is emitted when the
- * exported actions change (i.e. an action is added, removed, enabled,
- * disabled, or otherwise changed).
- * </para>
- * <para>
- * #GApplication is supported since Gio 2.26.
- * </para>
- * </refsect2>
+ * The #GApplication::startup signal lets you handle the application
+ * initialization for all of these in a single place.
+ *
+ * Regardless of which of these entry points is used to start the application,
+ * GApplication passes some <firstterm id="platform-data">platform
+ * data</firstterm> from the launching instance to the primary instance,
+ * in the form of a #GVariant dictionary mapping strings to variants.
+ * To use platform data, override the @before_emit or @after_emit virtual
+ * functions in your #GApplication subclass. When dealing with
+ * #GApplicationCommandline objects, the platform data is directly
+ * available via g_application_command_line_get_cwd(),
+ * g_application_command_line_get_environ() and
+ * g_application_command_line_get_platform_data().
+ *
+ * As the name indicates, the platform data may vary depending on the
+ * operating system, but it always includes the current directory (key
+ * "cwd"), and optionally the environment (ie the set of environment
+ * variables and their values) of the calling process (key "environ").
+ * The environment is only added to the platform data if the
+ * #G_APPLICATION_SEND_ENVIONMENT flag is set. GApplication subclasses
+ * can add their own platform data by overriding the @add_platform_data
+ * virtual function. For instance, #GtkApplication adds startup notification
+ * data in this way.
+ *
+ * To parse commandline arguments you may handle the
+ * #GApplication::command-line signal or override the local_command_line()
+ * vfunc, to parse them in either the primary instance or the local instance,
+ * respectively.

+ *
+ * This function is intended to be run from main() and its return value

+ * the @argc, @argv parameters from main() to this function, it is possible
+ * to pass %NULL if @argv is not available or commandline handling is not
+ * required.
+ *
+ * First, the local_command_line() virtual function is invoked.
+ * This function always runs on the local instance. It gets passed a pointer
+ * to a %NULL-terminated copy of @argv and is expected to remove the arguments
+ * that it handled (shifting up remaining arguments). See
+ * <xref linkend="gapplication-example-cmdline2"/> for an example of
+ * parsing @argv manually. Alternatively, you may use the #GOptionContext API,
+ * after setting <literal>argc = g_strv_length (argv);</literal>.
+ *
+ * The last argument to local_command_line() is a pointer to the @status
+ * variable which can used to set the exit status that is returned from
+ * g_application_run().
+ *
+ * If local_command_line() returns %TRUE, the command line is expected
+ * to be completely handled, including possibly registering as the primary
+ * instance, calling g_application_activate() or g_application_open(), etc.
+ *
+ * If local_command_line() returns %FALSE then the application is registered
+ * and the #GApplication::command-line signal is emitted in the primary
+ * instance (which may or may not be this instance). The signal handler
+ * gets passed a #GApplicationCommandline object that (among other things)
+ * contains the remaining commandline arguments that have not been handled
+ * by local_command_line().
+ *
+ * If the application has the %G_APPLICATION_HANDLES_COMMAND_LINE
+ * flag set then the default implementation of local_command_line()
+ * always returns %FALSE immediately, resulting in the commandline
+ * always being handled in the primary instance.
+ *
+ * Otherwise, the default implementation of local_command_line() tries
+ * to do a couple of things that are probably reasonable for most
+ * applications. First, g_application_register() is called to attempt
+ * to register the application. If that works, then the command line
+ * arguments are inspected. If no commandline arguments are given, then
+ * g_application_activate() is called. If commandline arguments are
+ * given and the %G_APPLICATION_HANDLES_OPEN flag is set then they
+ * are assumed to be filenames and g_application_open() is called.
+ *
+ * If you need to handle commandline arguments that are not filenames,
+ * and you don't mind commandline handling to happen in the primary
+ * instance, you should set %G_APPLICATION_HANDLED_COMMAND_LINE and
+ * process the commandline arguments in your #GApplication::command-line
+ * signal handler, either manually or using the #GOptionContext API.
+ *
+ * If you are interested in doing more complicated local handling of the
+ * commandline then you should implement your own #GApplication subclass
+ * and override local_command_line(). In this case, you most likely want
+ * to return %TRUE from your local_command_line() implementation to
+ * suppress the default handling. See
+ * <xref linkend="gapplication-example-cmdline2"/> for an example.
+ *
+ * If, after the above is done, the use count of the application is zero
+ * then the exit status is returned immediately. If the use count is
+ * non-zero then the default main context is iterated until the use count
+ * falls to zero, at which point 0 is returned.
+ *
+ * If the %G_APPLICATION_IS_SERVICE flag is set, then the exiting at
+ * use count of zero is delayed for a while (ie: the instance stays
+ * around to provide its <emphasis>service</emphasis> to others).
