In the continuous effort of better handling OOM in the kernel,
we want to move away from all AK::String usage. One of the final
pieces left to accomplish this goal is replacing all of the usages
of `String::formatted` with something that can actually propagate
failure.
The StringBuilder API was enhanced in the recent past to propagate
failure and thus a slightly modified version of what exists in
`AK::format` will work well for implementing failable format with
`KString`.
Previously, Virtio console ports would not show up in `/sys/dev/char/`.
Also adds support to `SystemServer` to create more than one console
port device in `/dev/` in the multiport case.
When calling set_selected_index() on ComboBox, allow its on_change
callback to be disabled. Fixes FontEditor window state erroneously
switching to modified when initializing between different slopes
and weights.
Fixes incorrect scale initialization and inconsistent margins, sets
minimum values for glyph width and height to 1, and labels page 1
more precisely as "Typeface" properties.
Fixes minor organizational inconsistency and zeroes initializations
for rows and columns as the previous values haven't been meaningful
since the map was converted to a scrollable widget. No functional
changes.
This will let us more easily organize and assign shortcuts to new
modes and transformations as they are built, and it generally looks
more polished as a uniform interface. Also adds a counterclockwise
option to the rotate action, moves Copy as Character to the edit
menu as it doesn't directly impact GlyphEditor, and makes the paint
and move modes exclusive checkables to make the editor's state more
visually obvious.
Previusly a cloned or newly loaded font was moved twice from main to
the constructor and then from constructor to an init routine where it
was finally used. The unmasked font is now moved only once, directly
to initialization, and redundant error checking is discarded.
GlyphBitmaps are considered present if they have a width greater
than zero. This adds a counterpart method for raw (unmasked) glyphs
and makes intent more explicit throughout FontEditor.
This adds plumbing for the Intl.DateTimeFormat object, constructor, and
prototype.
Note that unlike other Intl objects, the Intl.DateTimeFormat object has
a LibUnicode structure as a base. This is to prevent wild amounts of
code duplication between LibUnicode, Intl.DateTimeFormat, and other
not-yet-defined Intl structures, because there's 12 fields shared
between them.
For other keywords, allowed values per locale are generated at compile
time. But since the CLDR doesn't present hour cycles on a per-locale
basis, and hour cycles lookups depend on runtime data, we must handle
hour cycle keyword lookups differently than other keywords.
Unlike most data in the CLDR, hour cycles are not stored on a per-locale
basis. Instead, they are keyed by a string that is usually a region, but
sometimes is a locale. Therefore, given a locale, to determine the hour
cycles for that locale, we:
1. Check if the locale itself is assigned hour cycles.
2. If the locale has a region, check if that region is assigned hour
cycles.
3. Otherwise, maximize that locale, and if the maximized locale has
a region, check if that region is assigned hour cycles.
4. If the above all fail, fallback to the "001" region.
Further, each locale's default hour cycle is the first assigned hour
cycle.
This hasn't mattered yet by chance, because the source for all enums
contains names of the same case. But the enum generated for hour cycle
regions will have mixed case. Sort them case-insensitively in order to
traverse these names in the same order in both generate_enum and
generate_mapping.
