Timothy Flynn	7fad8c333d	LibWeb: Use forward-declarations of structured serialized types ... This reduces the rebuilt targets when touching StructuredSerialize.h from ~1200 to ~400. The remaining are due to generated IPC headers.	2025-07-18 10:09:02 -04:00
Luke Wilde	8e999bca62	LibWeb/CSP: Implement the style-src-attr directive	2025-07-18 11:58:04 +12:00
Luke Wilde	574b736156	LibWeb/CSP: Implement the style-src-elem directive	2025-07-18 11:58:04 +12:00
Luke Wilde	8b0b3b186f	LibWeb/CSP: Implement the style-src directive	2025-07-18 11:58:04 +12:00
Sam Atkins	6b53454b68	LibWeb/SVG: Move path data into Path.{h,cpp} ... More things need this than just the `<path>` element, so let's avoid having to include `SVGPathElement.h` in places that don't need it. Minor changes at the same time: - Wrap it in a Path class - Specify underlying type for PathInstructionType - Make a couple of free functions into methods - Give PathInstruction an operator== No functionality changes.	2025-07-17 13:59:23 -04:00
Aliaksandr Kalenik	b0ef7f4427	LibWeb: Defer invalidation sets processing until update_style() ... This change converts `Node::invalidate_style()` (invalidation sets overload) from eagerly doing tree traversal that marks elements affected by invalidation set to instead adding "pending invalidation sets" into `StyleInvalidator`, processing of which is deferred until the next `update_style()`. By doing that we sometimes substantially reduce amount of work done performing tree traversal that marks elements for style recalculation. Improves performance on Discord, were according to my measurements we were previously spending 20% of time in style invalidation, but now it's down to <1%.	2025-07-17 00:43:26 +02:00
Aliaksandr Kalenik	8cbe27b2f9	LibWeb: Move perform_pending_style_invalidations() in StyleInvalidator ... This change introduces StyleInvalidator as a preparation for upcoming change that will make `perform_pending_style_invalidations()` take care of pending invalidation sets.	2025-07-17 00:43:26 +02:00
Sam Atkins	0a5e8c2865	LibWeb/CSS: Implement "parse with a <syntax>" ... Uses the SyntaxNode tree to parse a list of ComponentValues into some kind of StyleValue.	2025-07-16 14:47:45 +01:00
Sam Atkins	ded2207762	LibWeb/CSS: Parse the CSS <syntax> type into a tree ... `<syntax>` is a limited subset of the "value definition syntax" used in CSS specs. It's used for `@property`'s `syntax` descriptor, and for the `type()` function in `attr()`.	2025-07-16 14:47:45 +01:00
Shannon Booth	15657ec4c3	LibWeb: Include or declare missing definitions for PseudoElement.h ... clangd was loudly complaining about this file.	2025-07-15 13:54:17 +01:00
Aliaksandr Kalenik	7e333cdcf7	LibWeb: Separate device pixel conversion helpers from PaintContext ... In the upcoming change, device pixel conversion of ClipFrame will happen during display list replay, where PaintContext is not available, so let’s move it out of PaintContext.	2025-07-14 15:48:28 +02:00
Luke Wilde	f50f23b19f	LibWeb/CSP: Implement the script-src-attr directive	2025-07-12 13:06:33 +12:00
Luke Wilde	f382bccc3d	LibWeb/CSP: Implement the script-src-elem directive	2025-07-12 13:06:33 +12:00
Aliaksandr Kalenik	410e82c9fd	LibWeb: Rearrange code such that a lot less files include Command.h ... With this change number of recompiled files after modification of `Command.h` goes down from >1000 to <100.	2025-07-11 17:37:27 +02:00
Luke Wilde	0cff47828d	LibWeb/CSP: Implement the script-src directive	2025-07-09 15:52:54 -06:00

Lucien Fiorini	f8b12614df	LibWeb/SVG: Add FEBlendElement	2025-07-09 18:07:12 +01:00
Lucien Fiorini	d3684a36b0	LibWeb/SVG: Add FEFloodElement	2025-07-09 18:07:12 +01:00
Sam Atkins	b6032b0fcd	LibWeb/CSS: Reimplement var()/attr() as arbitrary substitution functions ... "Arbitrary substitution functions" are a family of functions that includes var() and attr(). All of them resolve to an arbitrary set of component values that are not known at parse-time, so they have to be substituted at computed-value time. Besides it being nice to follow the spec closely, this means we'll be able to implement the others (such as `if()` and `inherit()`) more easily. The main omission here is the new "spread syntax", which can be implemented in the future.	2025-07-09 16:44:20 +01:00
Sam Atkins	9079be850b	LibWeb/CSS: Include guaranteed-invalid value in ComponentValue ... Treating these like any other ComponentValue means not having to convert between different types of Vector, and that we will be able to use TokenStream to parse the "argument grammars" of arbitrary substitution functions.	2025-07-09 16:44:20 +01:00
Luke Wilde	985a481b5a	LibWeb/CSP: Implement the object-src directive	2025-07-06 13:40:04 +12:00

Sam Atkins	e63d81b36e	LibWeb: Add CustomStateSet IDL type	2025-07-04 18:10:28 +01:00
Callum Law	62d138ebf7	LibWeb: Allow passing a resolution context to CSSStyleValue::to_color ... This will be used for resolving any calculated style values within the various `CSSColorValue` sub-classes. No functionality changes.	2025-07-04 13:18:55 +01:00
Tim Ledbetter	245905b833	LibWeb: Parse the border-image-slice property	2025-07-03 10:19:44 +01:00
Totto16	2ad3ce5d37	LibWeb: Implement basics for OffscreenCanvas ... This implements the basic interface, classes and functions for OffscreenCanvas. Many are still stubbed out and have many FIXMEs in them, but it is a basic skeleton.	2025-06-30 09:46:21 -06:00
Aliaksandr Kalenik	594194eb60	LibWeb: Skip serialization of implicit grid lines created during layout ... StyleValues created for grid-template-rows and grid-template-columns by GFC should not include `-start`/`-end` lines implicitly created by grid areas.	2025-06-25 20:45:48 +02:00
Aliaksandr Kalenik	af602b2555	LibWeb: Align CSS Grid properties parsing with the specification ... Reimplements `grid`, `grid-template`, `grid-template-rows`, and `grid-template-columns` in a way that uses a separate function for each grammar rule defined in the specification. This change results in many additional passing tests from the already imported WPT suite. Most of the remaining test failures are related to incorrect serialization of grid properties.	2025-06-21 22:07:08 +02:00
Jelle Raaijmakers	22bda8e5e2	LibWeb: Stub Geolocation API	2025-06-21 10:00:29 +02:00
Sam Atkins	498e143687	LibWeb/DOM: Stop including Element.h from AbstractElement.h ... We only need the forward declaration here, and this will let us include AbstractElement from Element.	2025-06-19 12:35:31 +01:00
Sam Atkins	ce380a59c7	LibWeb/DOM: Rename ElementReference to AbstractElement ... This isn't some kind of identifier, it's a handle on an actual Element or PseudoElement.	2025-06-19 12:35:31 +01:00
Sam Atkins	e7c2f0dd52	LibWeb: Make PseudoElement a class in its own right ... It's getting a bit large and complicated to be a struct hidden in DOM::Element.	2025-06-19 12:35:31 +01:00
Timothy Flynn	de34143a4e	LibWeb: Do not spin the event loop awaiting text track state changes ... The text track processing model would previously spin forever waiting for the track URL to change. It would then recursively invoke itself to handle the new URL, again entering the spin loop. This meant that tracks could easily cause event loop hangs. We now have an observer system to be notified when the track state changes instead. This lets us exit the processing model and move on.	2025-06-12 12:25:23 -04:00
Aliaksandr Kalenik	f53559cb55	LibWeb: Change Storage{Bottle,Bucket,Shelf} to be GC-allocated ... In upcoming changes StorageBottle will own pointers to GC-allocated objects, so it needs to be a GC-allocated object itself to avoid introducing more GC roots.	2025-06-12 17:04:35 +02:00
Tim Ledbetter	e2d0d8e2b9	LibWeb/CSS: Implement the scrollbar-color property ... This allows the user to set the scrollbar thumb and track colors.	2025-06-02 00:17:51 +02:00
Sam Atkins	6e45d8ba6c	LibWeb/CSS: Set enum sizes for PropertyID and Keyword ... The effect of this is hard to measure, but reducing them from 4 bytes each to 2 bytes can't hurt. :^)	2025-05-20 10:14:21 +12:00
Sam Atkins	c4bcbff59a	LibWeb/CSS: Set enum sizes for media query types ... This reduces `MediaFeature` from 112 to 104 bytes.	2025-05-20 10:14:21 +12:00
Sam Atkins	870f24f181	LibWeb/CSS: Add basic implementation of CSSMarginRule ... This is a bit under-specced, specifically there's no definition of CSSMarginDescriptors so I've gone with CSSStyleProperties for now. Gets us 17 WPT subtests.	2025-05-16 11:01:39 +01:00
Sam Atkins	aaf07ae30d	LibWeb: Add basic implementation of @page ... This doesn't support selectors, and the only descriptors for now are for margins.	2025-05-15 09:53:29 +01:00
Sam Atkins	398d2f9981	LibWeb/CSS: Implement pending-substitution value ... This is a special value temporarily assigned to longhands when their shorthand is unresolved, and then later replaced once that is resolved.	2025-05-14 11:46:47 +01:00
Sam Atkins	d1dadd43a1	LibWeb/CSS: Implement guaranteed-invalid value ... This is a special value produced when var/attr substitution fails, and is also the initial value for custom properties.	2025-05-14 11:46:47 +01:00
Timothy Flynn	7280ed6312	Meta: Enforce newlines around namespaces ... This has come up several times during code review, so let's just enforce it using a new clang-format 20 option.	2025-05-14 02:01:59 -06:00
stelar7	296d9d74d8	LibWeb/IDB: Implement IDBCursorWithValue interface	2025-05-13 10:48:40 -06:00
Sam Atkins	0925a32558	LibWeb/CSS: Extract a CSSDescriptors base class ... This holds the boilerplate that's needed by any CSSStyleDeclaration subclass that holds Descriptors. CSSFontFaceDescriptors now only has to worry about initialization and its own exposed properties.	2025-05-08 16:21:32 +01:00
Tim Ledbetter	c0f9b11070	LibWeb: Parse oblique font-style with an angle value	2025-05-03 12:05:22 +02:00
