Also, update the expected hash in the LibWeb TestHTMLTokenizer
regression test.
This is due to the "This comment has a few too many dashes." comment
token being updated.
Newline normalization will replace \r and \r\n with \n.
The spec specifically states
> Before the tokenization stage, the input stream must be preprocessed
> by normalizing newlines.
wheras this is implemented the processing during the tokenization
itself.
This should still exhibit the same behaviour, while keeping the
tokenization logic in the same place.
In 'NamedCharacterReference' we attempt to lookup the code point by a
identifier, eg apos; becomes '
This is done by passing the entire rest of the document to the
`HTML::code_points_from_entity` function.
However, before this change we didn't sent the final character which
meant if the document ended in a named character reference the lookup
would fail.
This fixes a crash of the browser when loading any page. LibWeb
immediately pops the 'running execution context' after creating an
interpreter, but it's needed to have a 'current realm' during
initialization of the ConsoleGlobalObject for NativeFunction::create()
to work.
Once this is done, we can immediately pop the execution context again.
The Spreadsheet application currently does not support undo/redo,
and with this update, we are starting the process of adding this feature
:-)
Additionally, the save dialog has been updated to use
GUI::MessageBox::ask_about_unsaved_changes() for system cohesity.
Spreadsheet: Add basic undo functinoality
The spreadsheet application now has basic support for undo. Testing of
this feature is limited, and may not work as intended yet.
Spreadsheet: Add callback when a cell's value is changed
In addition to the callback being added, this commit also exposes the
SheetModel class via a getter in SpreadSheetView.
Spreadsheet: Remove debug statements and use cell change callback
This commit uses the on_cell_data_change callback from within the
SheetModel class. This allows for us to push/pop changes to the undo
stack.
With this, we have basic Undo/Redo functionality :-)
Spreadsheet: Actually add window::set_modified
Spreadsheet: Const-correctness :-)
Spreadsheet: Reorder the edit menu actions
This follows the ECMA402 spec and means String.prototype.localeCompare
will automatically become actually locale aware once StringCompare is
actually implemented based on UTS #10.
This commit adds an initial implementation (without any real locale
support) of Collator Compare Functions, as well as the matching
CompareStrings AO. These two are used to implement the ECMA402 version
of String.localeCompare() and Int.Collator.compare().
Resolves one FIXME where we can now pass a realm, and sets the length
correctly in a bunch of places that previously didn't.
Also reduces the number of "format function name string from arbitrary
PropertyKey" implementations, although two more remain present in the
AST (used with ECMAScriptFunctionObjects, which is a different beast).
Also take a length argument and set the name and length properties
internally, instead of at the call site. Additionally, allow passing a
realm, prototype, and prefix.
The old FIXME asserting that Core::AnonymousBuffer cannot be invalid
or zero-sized is no longer accurate. Add a default constructor for
Audio::Buffer that has all invalid state instead of going to the OS to
allocate a 1 sample buffer for the "no more samples" states in the WAV
and FLAC plugins.
While quantifying assertions is very much meaningless, the specification
allows them with annex B's extended grammar for browsers, so read and
apply the quantifiers.
Fixes#12373.
Although it is not said that some of the elements need to be italic,
*most* browsers mark them as such to distinguish them from the normal
text, so let's do that too!
The entry we get from the active formatting elements list during the
Rewind step of "reconstruct the active formatting elements" can be a
marker. Previously we assumed it was not a marker, which can trigger
an assertion failure with certain malformed HTML.
If the entry in this step is a marker, the spec simply ignores it.
This is step 6 of the algorithm.
This also makes the index unsigned, as this algorithm is a no-op if
the list is empty.
Additionally, this also adds spec comments to this algorithm.
Fixes#12668.
This patch adds a default padding around the contents of text <input>
elements. It adds these defaults to the existing style attribute in
'HTMLInputElement::create_shadow_tree_if_needed()'.
Use a default padding for text <input> elements:
- padding-top and padding-bottom: 1px
- padding-left and padding-right: 2px
These values seems to align with what other browsers do.
This also adds a variant of {add,remove}_event_listener called
{add,remove}_event_listener_with_options.
This is used internally to perform {add,remove}_event_listener with a
default constructed options struct. It was done like this because
default constructing the Variant with the options struct requires the
struct defintions to be present, which requires us to include
AbortSignal.h, which would cause a circular include as AbortSignal.h
includes EventTarget.h.
Some grayscale JPG images might have the horizontal and vertical sample
factor set to 2. However, the macroblocks in these images are not
interleaved as they would be in color images.
Previously it would accept any DOMString, as we didn't support enums at
the time. Now it will only accept what's specified in the
DOMParserSupportedType enum.
This also adds spec comments to DOMParser::parse_from_string.
