We care about showing 'Assistant' app as fast as possible when the
hotkey is pressed. In order to do that, we can parse the `.af` file
ahead of time and have it ready to use.
To make Assistant useful we need a way to quickly trigger it. I've
added a new specialized event coming from the window server for when a
user is holding down 'Super' and hits 'Space'.
The Taskbar will be able to listen for this event and spawn a new
instance of the Assistant if it's not already running.
This includes checking that the target is a constructor, not just a
function, as well as switching the order of the list creation and
argument validation to match the specification, to ensure correct
exception throwing order.
This patch implements the IsSimpleParameterList static semantics for
ordinary function objects.
We now also create an unmapped arguments object for callee contexts
with non-simple parameter lists, instead of only doing it in strict
mode. Covered by test262.
This makes the implicit run-time assertion in PropertyName::to_string()
into an explicit compile-time requirement, removes a wasteful FlyString
-> PropertyName -> FlyString construction from NativeFunction::create()
and allows setting the function name to a null string for anonymous
native functions.
This regressed recently and would only output a bunch of '[object Foo]',
the reason being that String(value) failed in some cases - which is
easily fixed by trying that first and using Object.prototype.toString()
as a fallback in the case of an exception :^)
The unsigned shift right implementation was already doing this, but
the spec requires a mod32 of rhs before the shift for the signed shift
right implementation as well. Caught by UBSAN and oss-fuzz.
If the value we get after fmod in Value::to_u32 is negative, UBSAN
complains that -N is out of bounds for u32. An extra static cast to i64
makes it stop complaining. An alternative implementation could add 2^32
if the fmod'd value is negative. Caught by UBSAN and oss-fuzz.
Since being tiled means we restrict rendering a window to the screen it
is on (so that we don't "bleed" into an adjacent screen), we need to
untile it if the window either can't fit into the screen, or it is
detached from the screen edges.
Also add some tests to ensure that they _remain_ constexpr.
In general, any runtime assertions, weirdo C casts, pointer aliasing,
and such shenanigans should be gated behind the (helpfully newly added)
AK::is_constant_evaluated() function when the intention is to write
constexpr-capable code.
a.k.a. deliver promises of constexpr-ness :P
The launch_origin_rect parameter to create_window() specifies where on
screen the window was launched from. It's optional, but if you provide
it, the new window will have a short wireframe animation from the origin
to the initial window frame rect.
GUI::Window looks for the "__libgui_launch_origin_rect" environment
variable. Put your launch origin rect in there with the format
"<x>,<y>,<width>,<height>" and the first GUI::Window shown by the app
will use that as the launch origin rect.
Also it looks pretty neat, although I'm sure we can improve it. :^)
This patch adds the WindowServer::Animation class, which represents
a simple animation driven by the compositor.
An animation has a length (in milliseconds) and two hooks:
- on_update: called whenever the animation should render something.
- on_stop: called when the animation is finished and/or stopped.
This patch also ports the window minimization animation to this new
mechanism. :^)
