fix transformation logic for `:where` and `:is` pseudo-selectors
when these selectors were used in a chain. results were often broken,
the last letter of the selector was incorrectly trimmed.
see tests for examples
Fixes#58226
PR Close#58681
fix several use-cases where `:host` was used in or around pseudo-selectors
- `:host` followed by a comma inside pseudo-selectors
- `:host` outside of pseudo-selectors when another `:host` is present within
see tests for examples
PR Close#58681
parse constructions like `:where(:host-context(.foo))` correctly
revert logic which lead to decreased specificity if `:where` was applied
to another selector, for example `div` is transformed to `div[contenta]`
with specificity of (0,1,1) so `div:where(.foo)` should not decrease it
leading to `div[contenta]:where(.foo)` with the same specificity (0,1,1)
instead of `div:where(.foo[contenta])` with specificity equal to (0,0,1)
PR Close#57796
add support for nested and deeply nested (up to three levels) selectors,
parse multiple :host selectors, scope selectors within pseudo functions
PR Close#57796
allow css combinators within pseudo selector functions, parsing those
correctly. Similarly to previous version, don't break selectors
into part if combinators are within parenthesis, for example
`:where(.one > .two)`
PR Close#57796
fix scoping and transforming logic of the `shimCssText` for the
components with encapsulated view:
- add support for pseudo selector functions
- apply content scoping for inner selectors of `:is()` and `:where()`
- allow multiple comma separated selectors inside pseudo selectors

Previously, multiline selectors were being converted into single lines, resulting in sourcemap disruptions due to shifts in line numbers.
Closes#55508
PR Close#55509
In prod builds, selectors are optimized and spaces a removed. #48558 introduced a regression on selectors without spaces. This commit fixes tihs.
Fixes#49100
PR Close#49118
Prior to this commit, comments in CSS were being removed. This caused inline sourcemaps to break to the shift in lines.
This caused sourcemaps to break in the ESBuild based builder as this always adds comments at the top of the file with the filename.

```css
/* src/app/app.component.scss */

color: red;
background: transparent;
}

In Css, selectors with escaped characters require a space after if the following character is a hex character. ie: .\fc ber which matches class="über"
These escaped selectors happen for example when esbuild run with `optimization.minify`

PR Close#48558
apply different quality of life improvements to the shadow
css unit tests:
- refactor the tests so that they are nicely divided in multiple files
in a logical manner instead of having most of them all in a single big file
- remove the css normalization logic inconsistently used throughout the tests, which
causes tests to be inconsistent and it also introduced unintuitive checks
- provide a shared shim utility function (instead of re-defining it
multiple times)
- add a `toEqualCss` matcher that can be used in the tests in order to
match css strings without caring about spacing and indentation

Ensure that keyframes rules, defined within components with emulated
view encapsulation, are scoped to avoid collisions with keyframes in
other components.
This is achieved by renaming these keyframes to add a prefix that makes
them unique across the application.
In order to enable the handling of keyframes names defined as strings
the previous strategy of replacing quoted css content with `%QUOTED%`
(introduced in commit 7f689a2) has been removed and in its place now
only specific characters inside quotes are being replaced with
placeholder text (those are `;`, `:` and `,`, more can be added in
the future if the need arises).
Closes#33885
BREAKING CHANGE:
Keyframes names are now prefixed with the component's "scope name".
For example, the following keyframes rule in a component definition,
whose "scope name" is host-my-cmp:
@keyframes foo { ... }
will become:
@keyframes host-my-cmp_foo { ... }
Any TypeScript/JavaScript code which relied on the names of keyframes rules
will no longer match.
The recommended solutions in this case are to either:
- change the component's view encapsulation to the `None` or `ShadowDom`
- define keyframes rules in global stylesheets (e.g styles.css)
- define keyframes rules programmatically in code.
