This fixes#7792.
The visual glitches with card corners, and the screen-clear when
opening a menu, were both caused by the widgets having
`fill_with_background_color` set. We need that set most of the time,
so we just disable it for the duration of the game-over animation.
Also resove a FIXME that no longer applies. :^)
Previously, the timer started if you clicked within the game area,
whether that was on a card or not. Now, we only start when you click
on a card or otherwise attempt a move.
As a bonus, we now immediately update the status bar time indicator
on game start, instead of having to wait until 1 second has elapsed.
Previously, if a tab-move moved all the remaining cards to the
foundations, the game would not notice until you moved a card
away and then back again.
I had to add a 1-frame delay to starting the animation, so that it
would have time to re-paint the foundation in that case.
We were doing a *lot* of string-to-int conversion while creating a new
global object. This happened because Object::put() would try to convert
the property name (string) to an integer to see if it refers to an
indexed property.
Sidestep this issue by using PropertyName for the CommonPropertyNames
struct on VM (vm.names.foo), and giving PropertyName a flag that tells
us whether it's a string that *may be* a number.
All CommonPropertyNames are set up so they are known to not be numbers.
Some of the code assumed that chars were always signed while that is
not the case on ARM hosts.
Also, some of the code tried to use EOF (-1) in a way similar to what
fgetc() does, however instead of storing the characters in an int
variable a char was used.
While this seemed to work it also meant that character 0xFF would be
incorrectly seen as an end-of-file.
Careful reading of fgetc() reveals that fgetc() stores character
data in an int where valid characters are in the range of 0-255 and
the EOF value is explicitly outside of that range (usually -1).
A POSIX-compatibility fix was introduced in 64740a0214 to make the
compilation of the `diffutils` port work, which expected a
`char* const* argv` signature.
And indeed, the POSIX spec does not mention permutation of `argv`:
https://pubs.opengroup.org/onlinepubs/9699919799/functions/getopt.html
However, most implementations do modify `argv` as evidenced by
documentation such as:
https://refspecs.linuxbase.org/LSB_5.0.0/LSB-Core-generic
/LSB-Core-generic/libutil-getopt-3.html
"The function prototype was aligned with POSIX 1003.1-2008 (ISO/IEC
9945-2009) despite the fact that it modifies argv, and the library
maintainers are unwilling to change this."
Change the behavior back to permutate `argc` to allow for the following
command line argument order to work again:
unzip ./file.zip -o target-dir
Without this change, `./file.zip` in the example above would have been
ignored completely.
Gutter -- a space left of the text, before the ruler -- is not a part of
the ruler, nor should it be treated as such. This commit implements
gutter handling in LibGUI::TextEditor as part of mild cleaning up of the
gutter handling (breakpoint icons) in HackStudio's Editor.
This commit also enables separate theming of the gutter.
As mentioned on Discord earlier, we'll add these to all new functions
going forward - this is the backfill. Reasons:
- It makes you look at the spec, implementing based on MDN or V8
behavior is a no-go
- It makes finding the various functions that are non-compliant easier,
in the future everything should either have such a comment or, if it's
not from the spec at all, a comment explaining why that is the case
- It makes it easier to check whether a certain abstract operation is
implemented in LibJS, not all of them use the same name as the spec.
E.g. RejectPromise() is Promise::reject()
- It makes it easier to reason about vm.arguments(), e.g. when the
function has a rest parameter
- It makes it easier to see whether a certain function is from a
proposal or Annex B
Also:
- Add arguments to all functions and abstract operations that already
had a comment
- Fix some outdated section numbers
- Replace some ecma-international.org URLs with tc39.es
While this implementation should be complete it is based on HashMap's
iterator, which currently follows bucket-order instead of the required
insertion order. This can be simply fixed by replacing the underlying
HashMap member in Map with an enhanced one that maintains a linked
list in insertion order.
This will allow us to use these traits for other hash-based containers
(like Map). This commit also adds a special case for negative zero
values, because while the equality check used same_value_zero which is
negative/positive zero insensitive, the hash was not.
The autocomplete box closes on its own when the user tries to hover
over it because text_editor consideres hovering over the box to be
a leave_event. This commit stops that from happening.
This patch brings all of the previous work together and starts to
actually parse and decode frame information. Currently it only parses
the uncompressed header data (section 6.2 of the spec).
The VP9 specification requires a special decoding process to parse a
lot of the data read from a frame, so this BitStream wrapper implements
that behavior. These processes are defined in section 9 of the
VP9 spec.
This isn't tested all that well, as the PDF I am testing with only uses
it for black (which is trivial). It can be tested further when LibPDF
is able to process more complex PDFs that actually use this color space
non-trivially.
This code isn't _actually_ used as of right now, but I wrote it at the
same time as all of the code in the previous commit. I realized after
I wrote it that these hint tables aren't super useful if the parser
already has access to the full file. However, this will be useful if
we ever want to stream PDFs from the web (and possibly view them in
the browser).
