+Coding guide
+============
+
+Our goal is to have all JavaScript code in GNOME follow a consistent style. In
+a dynamic language like JavaScript, it is essential to be rigorous about style
+(and unit tests), or you rapidly end up with a spaghetti-code mess.
+
+A quick note
+------------
+
+Life isn't fun if you can't break the rules. If a rule seems unnecessarily
+restrictive while you're coding, ignore it, and let the patch reviewer decide
+what to do.
+
+Indentation and whitespace
+--------------------------
+
+Use four-space indents. Braces are on the same line as their associated
+statements.  You should only omit braces if *both* sides of the statement are
+on one line.
+
+* One space after the `function` keyword.  No space between the function name
+* in a declaration or a call.  One space before the parens in the `if`
+* statements, or `while`, or `for` loops.
+
+    function foo(a, b) {
+        let bar;
+
+        if (a > b)
+            bar = do_thing(a);
+        else
+            bar = do_thing(b);
+
+        if (var == 5) {
+            for (let i = 0; i < 10; i++) {
+                print(i);
+            }
+        } else {
+            print(20);
+        }
+    }
+
+Semicolons
+----------
+
+JavaScript allows omitting semicolons at the end of lines, but don't. Always
+end statements with a semicolon.
+
+js2-mode
+--------
+
+If using Emacs, do not use js2-mode. It is outdated and hasn't worked for a
+while. emacs now has a built-in JavaScript mode, js-mode, based on
+espresso-mode. It is the de facto emacs mode for JavaScript.
+
+File naming and creation
+------------------------
+
+For JavaScript files, use lowerCamelCase-style names, with a `.js` extension.
+
+We only use C where gjs/gobject-introspection is not available for the task, or
+where C would be cleaner. To work around limitations in
+gjs/gobject-introspection itself, add a new method in `shell-util.[ch]`.
+
+Like many other GNOME projects, we prefix our C source filenames with the
+library name followed by a dash, e.g. `shell-app-system.c`. Create a
+`-private.h` header when you want to share code internally in the
+library. These headers are not installed, distributed or introspected.
+
+Imports
+-------
+
+Use UpperCamelCase when importing modules to distinguish them from ordinary
+variables, e.g.
+
+    const GLib = imports.gi.GLib;
+
+Imports should be categorized into one of two places. The top-most import block
+should contain only "environment imports". These are either modules from
+gobject-introspection or modules added by gjs itself.
+
+The second block of imports should contain only "application imports". These
+are the JS code that is in the gnome-shell codebase,
+e.g. `imports.ui.popupMenu`.
+
+Each import block should be sorted alphabetically. Don't import modules you
+don't use.
+
+    const GLib = imports.gi.GLib;
+    const Gio = imports.gi.Gio;
+    const Lang = imports.lang;
+    const St = imports.gi.St;
+
+    const Main = imports.ui.main;
+    const Params = imports.misc.params;
+    const Tweener = imports.ui.tweener;
+    const Util = imports.misc.util;
+
+The alphabetical ordering should be done independently of the location of the
+location. Never reference `imports` in actual code.
+
+Constants
+---------
+
+We use CONSTANTS_CASE to define constants. All constants should be directly
+under the imports:
+
+    const MY_DBUS_INTERFACE = 'org.my.Interface';
+
+Variable declaration
+--------------------
+
+Always use either `const` or `let` when defining a variable.
+
+    // Iterating over an array
+    for (let i = 0; i < arr.length; ++i) {
+        let item = arr[i];
+    }
+
+    // Iterating over an object's properties
+    for (let prop in someobj) {
+        ...
+    }
+
+If you use "var" then the variable is added to function scope, not block scope.
+See [What's new in JavaScript 1.7](https://developer.mozilla.org/en/JavaScript/New_in_JavaScript/1.7#Block_scope_with_let_%28Merge_into_let_Statement%29)
+
+Classes
+-------
+
+There are many approaches to classes in JavaScript. We use our own class framework
+(sigh), which is built in gjs. The advantage is that it supports inheriting from
+GObjects, although this feature isn't used very often in the Shell itself.
+
+    const IconLabelMenuItem = new Lang.Class({
+        Name: 'IconLabelMenuItem',
+        Extends: PopupMenu.PopupMenuBaseItem,
+
+        _init: function(icon, label) {
+            this.parent({ reactive: false });
+            this.actor.add_child(icon);
+            this.actor.add_child(label);
+        },
+
+        open: function() {
+            log("menu opened!");
+        }
+    });
+
+* 'Name' is required. 'Extends' is optional. If you leave it out, you will
+  automatically inherit from Object.
+
+* Leave a blank line between the "class header" (Name, Extends, and other
+  things)  and the "class body" (methods). Leave a blank line between each
+  method.
+
+* No space before the colon, one space after.
+
+* No trailing comma after the last item.
+
+* Make sure to use a semicolon after the closing paren to the class. It's
+  still a giant function call, even though it may resemble a more
+  conventional syntax.
+
+GObject Introspection
+---------------------
+
+GObject Introspection is a powerful feature that allows us to have native
+bindings for almost any library built around GObject. If a library requires
+you to inherit from a type to use it, you can do so:
+
+    const MyClutterActor = new Lang.Class({
+        Name: 'MyClutterActor',
+        Extends: Clutter.Actor,
+
+        vfunc_get_preferred_width: function(actor, forHeight) {
+             return [100, 100];
+        },
+
+        vfunc_get_preferred_height: function(actor, forWidth) {
+             return [100, 100];
+        },
+
+        vfunc_paint: function(actor) {
+             let alloc = this.get_allocation_box();
+             Cogl.set_source_color4ub(255, 0, 0, 255);
+             Cogl.rectangle(alloc.x1, alloc.y1,
+                            alloc.x2, alloc.y2);
+        }
+    });
+
+Translatable strings, `environment.js`
+--------------------------------------
+
+We use gettext to translate the GNOME Shell into all the languages that GNOME
+supports. The `gettext` function is aliased globally as `_`, you do not need to
+explicitly import it. This is done through some magic in the
+[environment.js](http://git.gnome.org/browse/gnome-shell/tree/js/ui/environment.js)
+file. If you can't find a method that's used, it's probably either in gjs itself
+or installed on the global object from the Environment.
+
+Use 'single quotes' for programming strings that should not be translated
+and "double quotes" for strings that the user may see. This allows us to
+quickly find untranslated or mistranslated strings by grepping through the
+sources for double quotes without a gettext call around them.
+
+`actor` and `_delegate`
+-----------------------
+
+gjs allows us to set so-called "expando properties" on introspected objects,
+allowing us to treat them like any other. Because the Shell was built before
+you could inherit from GTypes natively in JS, we usually have a wrapper class
+that has a property called `actor`. We call this wrapper class the "delegate".
+
+We sometimes use expando properties to set a property called `_delegate` on
+the actor itself:
+
+    const MyClass = new Lang.Class({
+        Name: 'MyClass',
+
+        _init: function() {
+            this.actor = new St.Button({ text: "This is a button" });
+            this.actor._delegate = this;
+
+            this.actor.connect('clicked', Lang.bind(this, this._onClicked));
+        },
+
+        _onClicked: function(actor) {
+            actor.set_label("You clicked the button!");
+        }
+    });
+
+The 'delegate' property is important for anything which trying to get the
+delegate object from an associated actor. For instance, the drag and drop
+system calls the `handleDragOver` function on the delegate of a "drop target"
+when the user drags an item over it. If you do not set the `_delegate`
+property, your actor will not be able to be dropped onto.
+
+Functional style
+----------------
+
+JavaScript Array objects offer a lot of common functional programming
+capabilities such as forEach, map, filter and so on. You can use these when
+they make sense, but please don't have a spaghetti mess of function programming
+messed in a procedural style. Use your best judgment.
+
+Closures
+--------
+
+`this` will not be captured in a closure, it is relative to how the closure is
+invoked, not to the value of this where the closure is created, because "this"
+is a keyword with a value passed in at function invocation time, it is not a
+variable that can be captured in closures.
+
+All closures should be wrapped with a Lang.bind.
+
+    const Lang = imports.lang;
+
+    let closure = Lang.bind(this, function() { this._fnorbate(); });
+
+A more realistic example would be connecting to a signal on a method of a
+prototype:
+
+    const Lang = imports.lang;
+    const FnorbLib = imports.fborbLib;
+
+    const MyClass = new Lang.Class({
+        _init: function() {
+            let fnorb = new FnorbLib.Fnorb();
+            fnorb.connect('frobate', Lang.bind(this, this._onFnorbFrobate));
+        },
+
+        _onFnorbFrobate: function(fnorb) {
+            this._updateFnorb();
+        }
+    });
+
+Object literal syntax
+---------------------
+
+In JavaScript, these are equivalent:
+
+    foo = { 'bar': 42 };
+    foo = { bar: 42 };
+
+and so are these:
+
+    var b = foo['bar'];
+    var b = foo.bar;
+
+If your usage of an object is like an object, then you're defining "member
+variables." For member variables, use the no-quotes no-brackets syntax: `{ bar:
+42 }` `foo.bar`.
+
+If your usage of an object is like a hash table (and thus conceptually the keys
+can have special chars in them), don't use quotes, but use brackets: `{ bar: 42
+}`, `foo['bar']`.
+
+Getters, setters, and Tweener
+-----------------------------
+
+Getters and setters should be used when you are dealing with an API that is
+designed around setting properties, like Tweener. If you want to animate an
+arbitrary property, create a getter and setter, and use Tweener to animate the
+property.
+
+    const ANIMATION_TIME = 2000;
+
+    const MyClass = new Lang.Class({
+        Name: 'MyClass',
+
+        _init: function() {
+            this.actor = new St.BoxLayout();
+            this._position = 0;
+        },
+
+        get position() {
+            return this._position;
+        },
+
+        set position(value) {
+            this._position = value;
+            this.actor.set_position(value, value);
+        }
+    });
+
+    let myThing = new MyClass();
+    Tweener.addTween(myThing,
+                     { position: 100,
+                       time: ANIMATION_TIME,
+                       transition: 'easeOutQuad' });

+
+   Known differences from the ES6 specification:
+   - Map is a Lang.Class, not a ES6 class, so inheritance,
+     prototype, sealing, etc. work differently.
+   - items(), keys() and values() don't return iterators,
+     they return actual arrays, so they incur a full copy everytime
+     they're called, and they don't see changes if you mutate
+     the table while iterating
