Previously, the "Find Next Match" and "Find Previous Match" actions
simply updated the match index of the last query to be performed. This
led to incorrect results if the page had been modified after the last
query had been run.
`Page::find_in_page_next_match()` and
`Page::find_in_page_previous_match()` both now rerun the last query to
ensure the results are up to date before updating the match index.
The match index is also reset if the URL of the active document has
changed since the last query. The current match index is maintained if
only the URL fragment changes.
The values aren't that complex, so it doesn't make much sense to have a
dedicated generator for them. Parsing them manually also allows us to
have much more control over the produced values, so as a result of this
change, EasingStyleValue becomes much more ergonomic.
This was useful for code generation as reducing the size of the enums
had a notable impact on the size of the generated code. This is not the
case any longer.
This uses ICU for all of the Intl.PluralRules prototypes, which lets us
remove all data from our plural rules generator.
Plural rules depend directly on internal data from the number formatter,
so rather than creating a separate Locale::PluralRules class (which will
make accessing that data awkward), this adds plural rules APIs to the
existing Locale::NumberFormat.
Previously, the find in page function would fail to find text which was
split across multiple text nodes. For example, given the following
markup: `WH<span>F` the query `WHF` would previously fail to be
matched.
This is done by traversing all of the document's text nodes -
constructing a complete string to query against and keeping track of
the locations where that string is split across multiple nodes.
This is actually safe everywhere but in the topmost program scope.
For web compatibility reasons, we have to flush all top-level bindings
to the environment, in case a subsequent separate <script> program
comes looking for them.
Instead of displaying locals as "locN", we now show them as "name~N".
This makes it a lot easier to follow bytecode dumps, especially in
longer functions.
Note that we keep displaying the local index, to avoid confusion in case
there are multiple separate locals with the same name in one executable.
This commit adds the standard shortcuts for the Find Next and Find
Previous buttons on the find in page panel. These shortcuts are usually
F3 and Shift+F3 respectively, although Qt standard shortcuts may vary
across platforms.
Linking LibLocale publicly ensures that libicudata.a is also available
in all embedders of LibJS. Otherwise, ICU crashes in hard-to-track-down
ways at runtime when the data is not available.
The proposal has undergone quite a few normative changes since we last
synced with it. There was a time when it could not be implemented as it
was written, which is no longer the case. The resulting proposal has had
so many changes compared to our implementation, that it wouldn't make
sense to implement them commit-by-commit as we normally do. So instead,
this just implements the HEAD revision of the spec in one pass.
For Intl.DurationFormat, we will need to know a locale's hours-minutes
time separator, minutes-seconds time separator, and whether the locale
prefers digital hours to always display as 2 digits.
...and shadow tree with TextNode for "value" attribute is created.
This means InlineFormattingContext is used, and button's text now
respects CSS text-decoration properties and unicode-ranges.
Previously, navigating to or from `about:newtab` caused a crash due to
inadvertent null dereferences when checking whether a request or
response to a request should be blocked as mixed content.
The big improvement included in this commit is stack height mismatch
validation. There are other minor improvements included (related to the
validation algorithm). The method of supporting stack polymorphism has
changed to be more like the spec, which was necessary for confidently
handling stack height mismatches.
See:
https://webassembly.github.io/spec/core/appendix/algorithm.html
Previously, the validator had a lot of extraneous information related to
frames. Now, there's just one stack with all the necessary information
derived from it.
Previously, `memory.fill` filled memory with 4-byte values, even though
`memory.fill` should fill with just one byte. Also fixes some other
issues with some of the bulk memory instructions, like `memory.init`.
