To prepare for using plural rules within number & duration format, this
removes the NumberFormat::Plurality enumeration.
This also adds PluralCategory::ExactlyZero & PluralCategory::ExactlyOne.
These are used in locales like French, where PluralCategory::One really
means any value from 0.00 to 1.99. PluralCategory::ExactlyOne means only
the value 1, as the name implies. These exact rules are not known by the
general plural rules, they are explicitly for number / currency format.
The PluralCategory enum is currently generated for plural rules. Instead
of generating it, this moves the enum to the public LibUnicode header.
While it was nice to auto-discover these values, they are well defined
by TR-35, and we will need their values from within the number format
code generator (which can't rely on the plural rules generator having
run yet). Further, number format will require additional values in the
enum that plural rules doesn't know about.
This patch adds support for URLSearchParams to XHR::send() and
introduces the union type XMLHttpRequestBodyInit.
XHR::send() now has support for String and URLSearchParams.
Parts of our build system and scripts rely on the fact that we are
cross-compiling. For now, remove the "try to build natively" part to get
the build running and leave a TODO for later.
Plural rules in the CLDR are of the form:
"cs": {
"pluralRule-count-one": "i = 1 and v = 0 @integer 1",
"pluralRule-count-few": "i = 2..4 and v = 0 @integer 2~4",
"pluralRule-count-many": "v != 0 @decimal 0.0~1.5, 10.0, 100.0 ...",
"pluralRule-count-other": "@integer 0, 5~19, 100, 1000, 10000 ..."
}
The syntax is described here:
https://unicode.org/reports/tr35/tr35-numbers.html#Plural_rules_syntax
There are up to 2 sets of rules for each locale, a cardinal set and an
ordinal set. The approach here is to generate a C++ function for each
set of rules. Each condition in the rules (e.g. "i = 1 and v = 0") is
transpiled to a C++ if-statement within its function. Then lookup tables
are generated to match locales to their generated functions.
NOTE: -Wno-parentheses-equality is added to the LibUnicodeData compile
flags because the generated plural rules have lots of extra parentheses
(because e.g. we need to selectively negate and combine rules). The code
to generate only exactly the right number of parentheses is quite hairy,
so this just tells the compiler to ignore the extras.
This includes:
* The minimum number of days in a week for that week to count as the
first week of a new year.
* The day to be shown as the first day of the week in a calendar.
* The start/end days of the weekend.
Like the existing hour cycle data, week data is presented per-region in
the CLDR, rather than per-locale. The method to add likely subtags to a
locale to perform region lookups is the same.
The list of regions in the CLDR for hour cycle, minimum days, first day,
and weekend days are quite different. So rather than changing the
existing HourCycleRegion enum to a generic Region enum, we generate
separate enums for each of the week data fields. This allows each lookup
into these fields to remain simple array-based index access, without any
"jumps" for regions that don't have CLDR data for a field.
Currently contains just each locale's character order, but is set up to
easily add other text layout fields from the CLDR if ECMA-402 eventually
requires them.
The zone1970.tab file in the TZDB contains regional time zone data, some
of which we already parse for the system time zone settings map.
This parses the region names from that file and generates a list of time
zones which are used in each of those regions.
Add overrides for serenity_bin and serenity_lib to allow the actual
CMakeLists.txt from Userland to be used to build as many services as
possible without adding more clutter to Meta/Lagom/CMakeLists.txt
This matches the target names for the main serenity build, and will make
simplifying the Lagom build much easier going forward.
The LagomFoo name came from a time when we had both library builds in
the same CMake generated project and needed to deconflict the names.
In preparation for future refactoring of Lagom, let's use the variables
from GNUInstallDirs as much as possible for the helper macros and other
scripts used by the main build already.
This commit has no behavior changes.
In particular, this does not fix any of the wrong uses of the previous
default parameter (which used to be 'false', meaning "only replace the
first occurence in the string"). It simply replaces the default uses by
String::replace(..., ReplaceMode::FirstOnly), leaving them incorrect.
The main thing that is missing is validating certain pieces of data
against XML productions in well-formed mode, but nothing uses
well-formed mode right now.

The Mach-O file format does not have ELF's interposition rules, so this
flag does not make sense for macOS builds. While GCC silently accepts
the unsupported option, Clang issues a warning for it.
This commit makes it possible to build Lagom with LLVM from Homebrew.
I saw one site relying on this, where they are trying to set
XHR.responseType to "text/plain", which is not a valid responseType.
However, they also don't expect it to throw. The IDL spec special cases
enumerations to make it return instead of throwing in this case.
This uses optipng to check how much size can be reduced on PNG files. If
that's more than 2 KiB for at least one file, the check fails. As with
other checks, it doesn't run if optipng is not installed.
Previously we only threw an error if the enum was used as a function
argument. However, we are supposed to throw an error no matter the
context it is used in.
With the compilation of LibWeb, there's now quite a few cases where this
warning gets triggered. Rather than trying to fix them all right away,
we simply disable the warning for now.
This workaround was proposed by Andrew Kaster and BertalanD who promised
to open an issue about it!
Adding an image to man7/Audio-subsystem.md referencing a non-icon image
file in the same directory broke the automated build of the manpages
website, which was not prepared to handle this case.
By using RefPtrs to handle interfaces, the IDL parser could store cyclic
references to interfaces that import each other. One main example is the
"EventTarget.idl" and the "AbortSignal.idl" files, which both reference
each other. This caused huge amounts of memory not to be freed on exit.
To fix this, the parsed IDL interfaces are now stored in a HashTable of
NonnullOwnPtr<Interface>, which serves as the sole reference for every
parsed interface. All other usages of the Interface are changed to use
references instead of RefPtrs, or occasionally as raw pointers where
references don't fit inside the data structures.
This new HashTable is static, and as such will automatically be freed
prior to exiting the generator. This ensures that the code generator
properly cleans up after itself.
With this change, The IDL code generators can properly run on Lagom when
compiled with the -DENABLE_ADDRESS_SANITIZER=ON flag, and gets compiled
properly on the CI :^)
