+/**
+ * Namespace: WebHelper2
+ * Convenience library for running web applications
+ *
+ * WebHelper is a convenience library for displaying web applications inside a
+ * GTK container running WebKitGTK.
+ * WebHelper2 is the WebKit2 version.
+ *
+ * Although WebKit provides an easy way of communicating from GTK code to
+ * the in-browser Javascript, through the execute_script() method, it is not so
+ * easy to communicate the other way around.
+ *
+ * WebHelper solves that problem by detecting when the web page navigates to a
+ * custom action URI.
+ * The custom URI corresponds to a function that you define using
+ * <WebHelper.define_web_action()>, and you can pass parameters to the
+ * function.
+ *
+ * Another often-encountered problem is localizing text through the same API as
+ * your main GTK program.
+ * WebHelper solves this problem by allowing you to mark strings in your HTML
+ * page and translating them through a function of your choice when you run
+ * <WebHelper.translate_html()>.
+ * It also exposes a *gettext()* function in the client-side Javascript.
+ */
+
+/**
+ * Class: WebHelper
+ * Helper object for a WebKit2 web application
+ *
+ * Constructor parameters:
+ * props - a dictionary of construction properties and values (default {})
+ *
+ * The application class for your web application should create <WebHelper> in
+ * its *vfunc_dbus_register()* implementation, with appropriate
+ * <well-known-name> and <connection> parameters.
+ * After that, you can do further setup on it, such as defining web actions, in
+ * your *vfunc_startup()* implementation.
+ *
+ * There is no need to set up specially any web views that you create, unlike
+ * WebKit1 where you must set up <Application.web_actions_handler()>.
+ *
+ * Example:
+ * > const TestApplication = new Lang.Class({
+ * > Name: 'TestApplication',
+ * > Extends: Gtk.Application,
+ * >
+ * > vfunc_dbus_register: function (connection, object_path) {
+ * > this._webhelper = new WebHelper2.WebHelper({
+ * > well_known_name: this.application_id,
+ * > connection: connection,
+ * > });
+ * > return this.parent(connection, object_path);
+ * > },
+ * >
+ * > vfunc_startup: function () {
+ * > this.parent();
+ * >
+ * > this._webhelper.set_gettext(Gettext.dgettext.bind(null,
+ * > GETTEXT_DOMAIN));
+ * >
+ * > let window = new Gtk.Window();
+ * > let webview = new WebKit2.WebView();
+ * > webview.connect('load-changed', (webview, event) => {
+ * > if (event === WebKit2.LoadEvent.FINISHED)
+ * > this._webhelper.translate_html(webview, null, (obj, res) => {
+ * > this._webhelper.translate_html_finish(res);
+ * > window.show_all();
+ * > });
+ * > });
+ * > window.add(webview);
+ * > webview.load_uri('file:///path/to/my/page.html');
+ * > },
+ * >
+ * > vfunc_dbus_unregister: function (connection, object_path) {
+ * > this.parent(connection, object_path);
+ * > this._webhelper.unregister();
+ * > },
+ * >});
+ * >
+ * >let app = new TestApplication({
+ * > application_id: 'com.example.SmokeGrinder',
+ * >});
+ * >app.run(ARGV);
