This patch adds HTMLCanvasElement along with a LayoutCanvas object.
The DOM and layout parts are very similar to <img> elements.
The <canvas> element holds a Gfx::Bitmap which is sized according to
the "width" and "height" attributes on the element.
Calling .getContext("2d") on a <canvas> element gives you a context
object that draws into the underlying Gfx::Bitmap of the <canvas>.
The context weakly points to the <canvas> which allows it to outlive
the canvas element if needed.
This is really quite cool. :^)

This patch adds the EventTarget class and makes Node inherit from it.
You can register event listeners on an EventTarget, and when you call
dispatch_event() on it, the event listeners will get invoked.
An event listener is basically a wrapper around a JS::Function*.
This is pretty far from how DOM events should eventually work, but it's
a place to start and we'll build more on top of this. :^)

Services can now have their initial working directory
configured via `SystemServer.ini`.
This commit also configures Terminal's working directory
to be /home/anon

Weirdly enough, the "simple-scopes" test doesn't return undefined
anymore, at first I thought the scoping was somehow broken, turns out
the interpreter doesn't consider the returned y as the last evaluated
value anymore, possibly because it's undefined (?).

It is yet undecided how to name regional variants.
|
|
All Objects will now have ObjectPrototype as their prototype, unless
overridden.
|
|
This patch adds String.prototype.charAt() to demonstrate that prototype
property lookup works, and that you can call a prototype function on an
object, and it will do what you expect. :^)

This makes it easier to work with the german keyboard layout.
Some keys are left unset because their corresponding letters
aren't supported yet.

This was pleasantly simple! We don't have an ElementWrapper yet, so it
just returns a NodeWrapper, but it still basically works. :^)
|
|
This patch introduces the Wrapper and Wrappable classes.
Node now inherits from Wrappable, and can be wrapped in a GC-allocated
Bindings::NodeWrapper object. The only property we expose right now is
the very simple nodeName property.
When a Document's JS::Interpreter is first instantiated, we add a
"document" property with a DocumentWrapper object to the global object.
This is pretty cool! :^)
|
|
This patch begins integrating LibJS into LibWeb. Document holds the
JS::Interpreter for now, and it is created on demand when you first
call Document::interpreter().
We also add a simple "alert()" function to the global object.

Obey precedence and associativity rules when parsing expressions
with chained operators.

To make this work, also start passing Interpreter& to native functions.
|
|
This can be used to implement arbitrary functionality, callable from
JavaScript.
To make this work, I had to change the way CallExpression passes
arguments to the callee. Instead of a HashMap<String, Value>, we now
pass an ordered list of Argument { String name; Value value; }.
This patch includes a native "print(argument)" function. :^)

At last we can parse "hello friends".length :^)
|
|
Now that we have the beginnings of a parser, let's take the script to
run as a command-line argument and move all the test scripts into
/home/anon/js :^)
To run a script, simply use "js":
$ js my-script.js
To get an AST dump before execution, you can use "js -A"

Added a solitaire game. Currently there are graphics missing on some
of the cards, but the game is fully functional.
Press F12 to show the game-over animation manually.

Let's rename this to LibWeb since it aims to provide more parts of the
web platform than just HTML. :^)
|
|
LibCore's GZip is also moved into the Core namespace with this change.

Replaced GBP with a hash symbol, as unicode is not supported

This allows anon to shut down and reboot the system.
Fixes #775.

Simon Struthers drew a SerenityOS ladybug and since it's so cute,
I figured we could adopt it!

This feels a lot more consistent and Unixy:
create_shared_buffer() => shbuf_create()
share_buffer_with() => shbuf_allow_pid()
share_buffer_globally() => shbuf_allow_all()
get_shared_buffer() => shbuf_get()
release_shared_buffer() => shbuf_release()
seal_shared_buffer() => shbuf_seal()
get_shared_buffer_size() => shbuf_get_size()
Also, "shared_buffer_id" is shortened to "shbuf_id" all around.

I probably would've done INI config removal in another commit, but it
fit well here because I didn't want to pledge wpath for SystemMenu if I
didn't need to.
Frankly, that's something that I think should be done: allow ConfigFile
to be used read-only.

Only thing I don't like right now is the fact that we rely on the shell.

Fixes #1246.
