This also implements the CodePointAt abstract operation. This is needed
to handle invalid code units specific to the JavaScript spec, rather
than e.g. inserting replacement code units. This abstraction is public
because RegExp.prototype will also need it.
LibJS parses JavaScript as UTF-8, so when creating a string, we must
transcode it to UTF-16 to handle encoded surrogate pairs.
For example, consider the following string:
"\ud83d\ude00"
The UTF-8 encoding of this surrogate pair is:
0xf0 0x9f 0x98 0x80
However, LibJS will currently store the two surrogates individually as
UTF-8 encoded bytes, rather than combining the pair:
0xed 0xa0 0xb8, 0xed 0xb8 0x80
These are not equivalent. So, as String.prototype becomes UTF-16 aware,
this encoding will no longer work for abstractions like strict equality.
These methods did not require UTF-16 views, so just add test cases to
ensure they remain correct.
This also adds a couple of FIXME comments on tests that will fail even
with UTF-16 String.prototype support (for reasons such as lack of UTF-16
support in RegExp.prototype and Unicode case folding).
Depending on the values it might be difficult to figure out whether a
value is decimal or hexadecimal. So let's make this more obvious. Also
this allows copying and pasting those numbers into GNOME calculator and
probably also other apps which auto-detect the base.
When changing the theme, there were two Core::ConfigFile instances
(one class scoped -- m_config and one function scoped -- wm_config)
fighting over the file, resulting in not saving the new theme name
to the config. :^(
This makes WindowServer remember selected theme from the menu
after reboot!
The problem here was that the multi-byte UTF-8 encoded characters
were taking one byte too much, misaligning the data completely
and eventually crashing the program on the 128th frame.
This change reduces the for loop by one, as it has been already
calculated from the start_byte variable.
Applications previously had to create a GUI::Menubar object, add menus
to it, and then call GUI::Window::set_menubar().
This patch introduces GUI::Window::add_menu() which creates the menubar
automatically and adds items to it. Application code becomes slightly
simpler as a result. :^)
Previously, pressing 'x' for deletion on an otherwise empty line
insinuated a crash in TextEditor because a nonexistent code point was
accessed -- likewise for visual mode.
Instead of using the doubleclick_event this uses the current double-
click speed setting to check whether or not the colors of the double-
click icon should be inverted. This allows us to use the current (and
unsaved) setting for comparison instead of having to apply the settings
first.
This fixes not processing any messages read up until a connection
close is detected. We were returning from the function despite having
read some messages.
This enables changing monitor settings for each monitor individually.
In the event that changing a resolution causes screens to overlap we
now try to disperse the screens, although the algorithm currently
implemented may result in some rather unexpected layouts in certain
cases. We can still improve this logic, and eventually we're going to
have a widget where the screens can be arranged as desired.
If a screen layout cannot be applied, instead of failing to start
WindowServer try to fall back to an auto-generated screen layout with
the devices that are detected.
Also, be a bit smarter about changing the current screen layout.
Instead of closing all framebuffers and bringing them back up, keep
what we can and only change resolution on those that we need to change
them on. To make this work we also need to move away from using an
array of structures to hold compositor related per-screen data to
attaching it to the Screen itself, which makes re-using a screen much
simpler.
