The plan is to extend what currently is known as "CPUGraph" and let the
SystemServer spawn multiple instances of it - which then can show memory
or network usages as well :^)
Simply renaming the applet is the first step.
Add an implementation of CanvasRenderingContext2DWrapper.strokeRect().
While implementing this I fixed fillRect() and the new strokeRect() to
honor the .scale() and .translate() values that had previously been plumbed.
Also enhance the canvas.html demo to utilize strokeRect(), scale(), and translate().
Prior to this, we ran the DHCP client as a high-priority service, but
making the system feel laggy "for some network stuff" is not the
greatest of ideas :^)
Scripts loaded in this way will block the parser until they finish
executing. This means that they see the DOM before the whole document
has been fully parsed. This is all normal, of course.
To make this work, I changed the way we notify DOM nodes about tree
insertion. The inserted_into() callbacks are now incrementally invoked
during parse, as each node is appended to its parent.
To accomodate inline scripts and inline style sheets, we now also have
a children_changed() callback which is invoked on any parent when it
has children added/removed.
This adds:
- A global Date object (with `length` property and `now` function)
- The Date constructor (no arguments yet)
- The Date prototype (with `get*` functions)
I made some mistakes in the selector parsing code. It's now able to
parse selectors composed of multiple complex selectors, instead of just
one complex selector.
This currently returns a JS::Array of elements matching a selector.
The more correct behavior would be to return a static NodeList, but as
we don't have NodeLists right now, that'll be a task for the future.
This patchset adds a Button to the toolbar (right next to the location field)
with a star icon. The star is white if the currently visited url is not yet
bookmarked and yellow if a bookmark for the url exists.
After adding or removing a bookmark, the bookmark json file is synced to disk.
Therefore, some new pledge/unveil's have been added.
This patchset adds a bookmark bar that is backed by a json file backend.
The json file is loaded and checked for the format. According to the
format, the bookmarks bar is populated with the bookmark items.
If the bookmarks do not fit into one line, an expader button is shown
that brings up a menu containing the missing bookmark items.
There is currently no way to add or remove bookmarks. A hover over a
bookmark is also not yet showing the url in the statusbar.
Getting the innerHTML property will recurse through the subtree inside
the element and serialize it into a string as it goes.
Setting it will parse the set value as an HTML fragment. It will then
remove all current children of the element and replace them with all
the children inside the parsed fragment.
Setting element.innerHTML will currently force a complete rebuild of
the document's layout tree.
This is pretty neat! :^)
You can now throw an expression to the nearest catcher! :^)
To support throwing arbitrary values, I added an Exception class that
sits as a wrapper around whatever is thrown. In the future it will be
a logical place to store a call stack.
You can now throw exceptions by calling Interpreter::throw_exception().
Anyone who calls ASTNode::execute() needs to check afterwards if the
Interpreter now has an exception(), and if so, stop what they're doing
and simply return.
When catching an exception, we'll first execute the CatchClause node
if present. After that, we'll execute the finalizer block if present.
This is unlikely to be completely correct, but it's a start! :^)
This momentarily handles the CSS property "position: absolute;" in
combination with the properties "top" and "left", so that elements can
be placed anywhere on the page independently from their parents.
Statically positioned elements ignore absolute positioned elements when
calculating their position as they don't take up space.
We now support rAF, driven by GUI::DisplayLink callbacks. It's a bit
strange how we keep registering new callbacks over and over.
That's something we can definitely optimize.
This allows you to update animations/whatever without doing it more
often than the browser can display.
This function is ultimately supposed to be generic and allow any |this|
that has a length property, but for now it only works on our own Array
object type.
I'm not completely thrilled about Object::get() and Object::put() doing
special-case stuff for arrays, and we should probably come up with a
better abstraction for it.
But at least it works for now, which is really nice. :^)
This makes it possible to write shorter CSS. Instead of writing
.foo {
border-width: 3px;
border-style: solid;
border-color: blue;
}
it is now possible to write
.foo {
border: 3px solid blue;
}
while the order of values is irrelevant.
Currently only the basic values are supported. More values should be
added in the future.
Three more value specific parse functions were added:
parse_line_width, parse_color, and parse_line_style
Additionally a few test cases were added to borders.html.
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. :^)
