* Move Stylo to its own repo (#31350)Delan Azabani2024-02-2722-6632/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove packages that were moved to external repo * Add workspace dependencies pointing to 2023-06-14 branch * Fix servo-tidy.toml errors * Update commit to include #31346 * Update commit to include servo/stylo#2 * Move css-properties.json lookup to target/doc/stylo * Remove dependency on vendored mako in favour of pypi dependency This also removes etc/ci/generate_workflow.py, which has been unused since at least 9e71bd6a7010d6e5723831696ae0ebe26b47682f. * Add temporary code to debug Windows test failures * Fix failures on Windows due to custom target dir * Update commit to include servo/stylo#3 * Fix license in tests/unit/style/build.rs * Document how to build with local Stylo in Cargo.toml
* Revert remaining Stylo changes (#31408)Delan Azabani2024-02-221-2/+1
| | | | | * Revert remaining changes from Stylo split-into-commits branch * Do the minimum amount of formatting to appease mach test-tidy
* style: Remove dependency on servo_url (#31358)Martin Robinson2024-02-161-2/+29
| | | | | In order for stylo to be a separate crate, it needs to depend on less things from Servo. This change makes it so that stylo no longer depends on servo_url.
* style: Add a `static_prefs` implementation (#31351)Martin Robinson2024-02-143-27/+3
| | | | This will eventually be part of the stylo crate and reduces the diff between our verson of style and upstream's.

* style: [css-nesting] Do a first pass at parsing nested rules mixed with ↵Emilio Cobos Álvarez2023-11-247-173/+324
| | | | | | | | | | | | | | | | | | declarations Plumb everything up. This factors out declaration and rule parsing so we share the code with the regular declaration parser. This could be made a bit nicer in the future. We need to decide what to do for @page and @keyframe (it seems conditional rules inside ought to work, but that's not so easy because per spec we create a nested style rule). But this is a first pass that passes a good chunk of the tests. There are other fixups to cssom, and I think some of the tests we fail are actually wrong...

* style: Disable NSCAP_FEATURE_USE_BASEEmilio Cobos Álvarez2023-11-241-6/+2
| | | | | | | | | | | | This is a relatively small code size regression (130k on windows and macOS, 180k on Linux), for a few high confidence improvements in speedometer 3. See link in the bug. If this sticks, we can actually clean up a bunch of code, and eventually unify RefPtr and nsCOMPtr. But I want this to be on the tree for a while before doing more aggressive refactorings / actually removing the code. Differential Revision: https://phabricator.services.mozilla.com/D178267

| | | | | | | | | | | | | | | This changes the cssparser setup to: * Avoid having to do copies of the ParsingContext all over the place, which is useful because I plan to stash more nesting state in there. * Use the new RuleBodyParser which allows parsing qualified rules, declarations, and so on. Though we still don't use this anywhere. The next step is to join NestedRuleParser and PropertyDeclarationParser, so that we can parse declarations in a lot of the nested rules as well.

* style: [css-nesting] Process nested rules at cascade data rebuildEmilio Cobos Álvarez2023-11-211-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | More nesting plumbing. Still does nothing because we don't parse the nested rules. Should be trivial to prove this patch doesn't change any behavior so far, but I want to land it on its own because it can have performance implications. This follows the pattern of what we do with other rules like layers and container conditions, that is, keep the ancestor selectors in a stack, and poke at the last one in order to replace the ancestor. This changes the behavior of replace_parent_selector as with the newer version of the spec, stuff like: div { .foo { stuff } } Should work as `div .foo`. A test is added for this case.

* style: Convert RGBA to AbsoluteColor for computed/animated/resolved CSS colorsTiaan Louw2023-11-211-2/+5
| | | | | | | | | | | | | | Computed color values will not be in the correct format, closer to the one specified by the author. This also means that colors accross the code are stored now as AbsoluteColor or StyleAbsoluteColor. This allows color space/gamut information to be available for use. Some animation related test failures had to be changed, because colors now has greater precision. Animated a color now causes a lot more animation updates, which was not initially expected.

It represents any kind of color that has absolute numerical values. It is also tied to a color space and therefore can be trivially converted to another color space.

* style: Partial fix for container units in pseudo-elementsOriol Brufau2023-11-041-12/+9
| | | | | | | | | | | | | | When apply_declarations is used for a pseudo-element, make it pass the parent_style as the originating_element_style for container queries. This requires changing some parameters from Option<&Arc<ComputedValues>> to Option<&ComputedValues>. It's not a complete solution, since e.g. parent_style is not the style of the originating element of a ::backdrop. But here it's not as simple as in D164908, so leaving these details for later.

| | | | | | | | | | | | It was made a bitfield so that we could include style. But then style containment was removed and the bitfield keeps causing us to do wrong check (since INLINE_SIZE intersects SIZE). So just make it an enum.
