+# Changelog
+
+All notable changes to this project will be documented in this file.
+This project adheres to [Semantic Versioning](https://semver.org/).
+
+Please also have a look at our
+[API and deprecation policy](docs/API-and-deprecation-policy.md).
+
+## x.y.z
+
+### Added
+
+- Interface `RuleContainer` for `RuleSet` `Rule` manipulation methods (#1256)
+- `RuleSet::removeMatchingRules()` method
+ (for the implementing classes `AtRuleSet` and `DeclarationBlock`) (#1249)
+- `RuleSet::removeAllRules()` method
+ (for the implementing classes `AtRuleSet` and `DeclarationBlock`) (#1249)
+- Add Interface `CSSElement` (#1231)
+- Methods `getLineNumber` and `getColumnNumber` which return a nullable `int`
+ for the following classes:
+ `Comment`, `CSSList`, `SourceException`, `Charset`, `CSSNamespace`, `Import`,
+ `Rule`, `DeclarationBlock`, `RuleSet`, `CSSFunction`, `Value` (#1225, #1263)
+- `Positionable` interface for CSS items that may have a position
+ (line and perhaps column number) in the parsed CSS (#1221)
+- Partial support for CSS Color Module Level 4:
+ - `rgb` and `rgba`, and `hsl` and `hsla` are now aliases (#797}
+ - Parse color functions that use the "modern" syntax (#800)
+ - Render RGB functions with "modern" syntax when required (#840)
+ - Support `none` as color function component value (#859)
+- Add a class diagram to the README (#482)
+- Add more tests (#449)
+
+### Changed
+
+- `setPosition()` (in `Rule` and other classes) now has fluent interface,
+ returning itself (#1259)
+- `RuleSet::removeRule()` now only allows `Rule` as the parameter
+ (implementing classes are `AtRuleSet` and `DeclarationBlock`);
+ use `removeMatchingRules()` or `removeAllRules()` for other functions (#1255)
+- `RuleSet::getRules()` and `getRulesAssoc()` now only allow `string` or `null`
+ as the parameter (implementing classes are `AtRuleSet` and `DeclarationBlock`)
+ (#1253)
+- Parameters for `getAllValues()` are deconflated, so it now takes three (all
+ optional), allowing `$element` and `$ruleSearchPattern` to be specified
+ separately (#1241)
+- Implement `Positionable` in the following CSS item classes:
+ `Comment`, `CSSList`, `SourceException`, `Charset`, `CSSNamespace`, `Import`,
+ `Rule`, `DeclarationBlock`, `RuleSet`, `CSSFunction`, `Value` (#1225)
+- Initialize `KeyFrame` properties to sensible defaults (#1146)
+- Make `OutputFormat` `final` (#1128)
+- Make `Selector` a `Renderable` (#1017)
+- Only allow `string` for some `OutputFormat` properties (#885)
+- Use more native type declarations and strict mode
+ (#641, #772, #774, #778, #804, #841, #873, #875, #891, #922, #923, #933, #958,
+ #964, #967, #1000, #1044, #1134, #1136, #1137, #1139, #1140, #1141, #1145,
+ #1162, #1163, #1166, #1172, #1174, #1178, #1179, #1181, #1183, #1184, #1186,
+ #1187, #1190, #1192, #1193, #1203)
+- Add visibility to all class/interface constants (#469)
+
+### Deprecated
+
+- Passing a `string` or `null` to `RuleSet::removeRule()` is deprecated
+ (implementing classes are `AtRuleSet` and `DeclarationBlock`);
+ use `removeMatchingRules()` or `removeAllRules()` instead (#1249)
+- Passing a `Rule` to `RuleSet::getRules()` or `getRulesAssoc()` is deprecated,
+ affecting the implementing classes `AtRuleSet` and `DeclarationBlock`
+ (call e.g. `getRules($rule->getRule())` instead) (#1248)
+- Passing a string as the first argument to `getAllValues()` is deprecated;
+ the search pattern should now be passed as the second argument (#1241)
+- Passing a Boolean as the second argument to `getAllValues()` is deprecated;
+ the flag for searching in function arguments should now be passed as the third
+ argument (#1241)
+- `getLineNo()` is deprecated in these classes (use `getLineNumber()` instead):

+ `Rule`, `DeclarationBlock`, `RuleSet`, `CSSFunction`, `Value` (#1225, #1233)
+- `Rule::getColNo()` is deprecated (use `getColumnNumber()` instead)
+ (#1225, #1233)
+- Providing zero as the line number argument to `Rule::setPosition()` is
+ deprecated (pass `null` instead if there is no line number) (#1225, #1233)
+
+### Removed
+

+ supported and will not work;
+ the search pattern should now be passed as the second argument (#1243)

+### Features
+
+* Support for PHP 8.x
+* PHPDoc annotations
+* Allow usage of CSS variables inside color functions (by parsing them as
+ regular functions)
+* Use PSR-12 code style
+* *No deprecations*
+
+### Bugfixes
+
+* Improved handling of whitespace in `calc()`
+* Fix parsing units whose prefix is also a valid unit, like `vmin`
+* Allow passing an object to `CSSList#replace`
+* Fix PHP 7.3 warnings
+* Correctly parse keyframes with `%`
+* Don’t convert large numbers to scientific notation
+* Allow a file to end after an `@import`
+* Preserve case of CSS variables as specced
+* Allow identifiers to use escapes the same way as strings
+* No longer use `eval` for the comparison in `getSelectorsBySpecificity`, in
+ case it gets passed untrusted input (CVE-2020-13756). Also fixed in 8.3.1,
+ 8.2.1, 8.1.1, 8.0.1, 7.0.4, 6.0.2, 5.2.1, 5.1.3, 5.0.9, 4.0.1, 3.0.1, 2.0.1,
+ 1.0.1.
+* Prevent an infinite loop when parsing invalid grid line names
+* Remove invalid unit `vm`
+* Retain rule order after expanding shorthands
+
+### Backwards-incompatible changes
+
+* PHP ≥ 5.6 is now required
+* HHVM compatibility target dropped
+
+## 8.3.0 (2019-02-22)
+
+* Refactor parsing logic to mostly reside in the class files whose data
+ structure is to be parsed (this should eventually allow us to unit-test
+ specific parts of the parsing logic individually).
+* Fix error in parsing `calc` expessions when the first operand is a negative
+ number, thanks to @raxbg.
+* Support parsing CSS4 colors in hex notation with alpha values, thanks to
+ @raxbg.
+* Swallow more errors in lenient mode, thanks to @raxbg.
+* Allow specifying arbitrary strings to output before and after declaration
+ blocks, thanks to @westonruter.
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 8.2.0 (2018-07-13)
+
+* Support parsing `calc()`, thanks to @raxbg.
+* Support parsing grid-lines, again thanks to @raxbg.
+* Support parsing legacy IE filters (`progid:`) in lenient mode, thanks to
+ @FMCorz
+* Performance improvements parsing large files, again thanks to @FMCorz
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 8.1.0 (2016-07-19)
+
+* Comments are no longer silently ignored but stored with the object with which
+ they appear (no render support, though). Thanks to @FMCorz.
+* The IE hacks using `\0` and `\9` can now be parsed (and rendered) in lenient
+ mode. Thanks (again) to @FMCorz.
+* Media queries with or without spaces before the query are parsed. Still no
+ *real* parsing support, though. Sorry…
+* PHPUnit is now listed as a dev-dependency in composer.json.
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 8.0.0 (2016-06-30)
+
+* Store source CSS line numbers in tokens and parsing exceptions.
+* *No deprecations*
+
+### Backwards-incompatible changes
+
+* Unrecoverable parser errors throw an exception of type
+ `Sabberworm\CSS\Parsing\SourceException` instead of `\Exception`.
+
+## 7.0.3 (2016-04-27)
+
+* Fixed parsing empty CSS when multibyte is off
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 7.0.2 (2016-02-11)
+
+* 150 time performance boost thanks
+ to @[ossinkine](https://github.com/ossinkine)
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 7.0.1 (2015-12-25)
+
+* No more suppressed `E_NOTICE`
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 7.0.0 (2015-08-24)
+
+* Compatibility with PHP 7. Well timed, eh?
+* *No deprecations*
+
+### Backwards-incompatible changes
+
+* The `Sabberworm\CSS\Value\String` class has been renamed to
+ `Sabberworm\CSS\Value\CSSString`.
+
+## 6.0.1 (2015-08-24)
+
+* Remove some declarations in interfaces incompatible with PHP 5.3 (< 5.3.9)
+* *No deprecations*
+
+## 6.0.0 (2014-07-03)
+
+* Format output using Sabberworm\CSS\OutputFormat
+* *No backwards-incompatible changes*
+
+### Deprecations
+
+* The parse() method replaces __toString with an optional argument (instance of
+ the OutputFormat class)
+
+## 5.2.0 (2014-06-30)
+
+* Support removing a selector from a declaration block using
+ `$oBlock->removeSelector($mSelector)`
+* Introduce a specialized exception (Sabberworm\CSS\Parsing\OuputException) for
+ exceptions during output rendering
+
+* *No deprecations*
+
+#### Backwards-incompatible changes
+
+* Outputting a declaration block that has no selectors throws an OuputException
+ instead of outputting an invalid ` {…}` into the CSS document.
+
+## 5.1.2 (2013-10-30)
+
+* Remove the use of consumeUntil in comment parsing. This makes it possible to
+ parse comments such as `/** Perfectly valid **/`
+* Add fr relative size unit
+* Fix some issues with HHVM
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.1.1 (2013-10-28)
+
+* Updated CHANGELOG.md to reflect changes since 5.0.4
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 5.1.0 (2013-10-24)

+
+## 3.0.0 (2013-03-06)
+
+* Support for lenient parsing (on by default)
+* *No deprecations*
+
+### Backwards-incompatible changes
+
+* All properties (like whether or not to use `mb_`-functions, which default
+ charset to use and – new – whether or not to be forgiving when parsing) are
+ now encapsulated in an instance of `Sabberworm\CSS\Settings` which can be
+ passed as the second argument to `Sabberworm\CSS\Parser->__construct()`.
+* Specifying a charset as the second argument to
+ `Sabberworm\CSS\Parser->__construct()` is no longer supported. Use
+ `Sabberworm\CSS\Settings::create()->withDefaultCharset('some-charset')`
+ instead.
+* Setting `Sabberworm\CSS\Parser->bUseMbFunctions` has no effect. Use
+ `Sabberworm\CSS\Settings::create()->withMultibyteSupport(true/false)` instead.
+* `Sabberworm\CSS\Parser->parse()` may throw a
+ `Sabberworm\CSS\Parsing\UnexpectedTokenException` when in strict parsing mode.
+
+## 2.0.0 (2013-01-29)
+
+* Allow multiple rules of the same type per rule set
+
+### Backwards-incompatible changes
+
+* `Sabberworm\CSS\RuleSet->getRules()` returns an index-based array instead of
+ an associative array. Use `Sabberworm\CSS\RuleSet->getRulesAssoc()` (which
+ eliminates duplicate rules and lets the later rule of the same name win).
+* `Sabberworm\CSS\RuleSet->removeRule()` works as it did before except when
+ passed an instance of `Sabberworm\CSS\Rule\Rule`, in which case it would only
+ remove the exact rule given instead of all the rules of the same type. To get
+ the old behaviour, use `Sabberworm\CSS\RuleSet->removeRule($oRule->getRule()`;
+
+## 1.0
+
+Initial release of a stable public API.
+
+## 0.9
+
+Last version not to use PSR-0 project organization semantics.

+# Contributing to PHP-CSS-Parser
+
+Those that wish to contribute bug fixes, new features, refactorings and
+clean-up to PHP-CSS-Parser are more than welcome.
+
+When you contribute, please take the following things into account:
+
+## Contributor Code of Conduct
+
+Please note that this project is released with a
+[Contributor Code of Conduct](../CODE_OF_CONDUCT.md). By participating in this
+project, you agree to abide by its terms.
+
+## General workflow
+
+This is the workflow for contributing changes to this project::
+
+1. [Fork the Git repository](https://docs.github.com/en/get-started/exploring-projects-on-github/contributing-to-a-project).
+1. Clone your forked repository locally and install the development
+ dependencies.
+1. Create a local branch for your changes.
+1. Add unit tests for your changes.
+ These tests should fail without your changes.
+1. Add your changes. Your added unit tests now should pass, and no other tests
+ should be broken. Check that your changes follow the same coding style as the
+ rest of the project.
+1. Add a changelog entry, newest on top.
+1. Commit and push your changes.
+1. [Create a pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests)
+ for your changes.
+1. Check that the CI build is green. (If it is not, fix the problems listed.)
+ Please note that for first-time contributors, you will need to wait for a
+ maintainer to allow your CI build to run.
+1. Wait for a review by the maintainers.
+1. Polish your changes as needed until they are ready to be merged.
+
+## About code reviews
+
+After you have submitted a pull request, the maintainers will review your
+changes. This will probably result in quite a few comments on ways to improve
+your pull request. This project receives contributions from developers around
+the world, so we need the code to be the most consistent, readable, and
+maintainable that it can be.
+
+Please do not feel frustrated by this - instead please view this both as our
+contribution to your pull request as well as a way to learn more about
+improving code quality.
+
+If you would like to know whether an idea would fit in the general strategy of
+this project or would like to get feedback on the best architecture for your
+ideas, we propose you open a ticket first and discuss your ideas there
+first before investing a lot of time in writing code.
+
+## Install the development dependencies
+
+To install the most important development dependencies, please run the following
+command:
+
+```bash
+composer install
+```
+
+We also have some optional development dependencies that require higher PHP
+versions than the lowest PHP version this project supports. Hence they are not
+installed by default.
+
+To install these, you will need to have [PHIVE](https://phar.io/) installed.
+You can then run the following command:
+
+```bash
+phive install
+```
+
+## Unit-test your changes
+
+Please cover all changes with unit tests and make sure that your code does not
+break any existing tests. We will only merge pull requests that include full
+code coverage of the fixed bugs and the new features.
+
+To run the existing PHPUnit tests, run this command:
+
+```bash
+composer ci:tests:unit
+```
+
+## Coding Style
+
+Please use the same coding style
+([PER 2.0](https://www.php-fig.org/per/coding-style/)) as the rest of the code.
+Indentation is four spaces.
+
+We will only merge pull requests that follow the project's coding style.
+
+Please check your code with the provided static code analysis tools:
+
+```bash
+composer ci:static
+```
+
+Please make your code clean, well-readable and easy to understand.
+
+If you add new methods or fields, please add proper PHPDoc for the new
+methods/fields. Please use grammatically correct, complete sentences in the
+code documentation.
+
+You can autoformat your code using the following command:
+
+```bash
+composer fix
+```
+
+## Git commits
+
+Commit message should have a <= 50-character summary, optionally followed by a
+blank line and a more in depth description of 79 characters per line.
+
+Please use grammatically correct, complete sentences in the commit messages.
+
+Also, please prefix the subject line of the commit message with either
+`[FEATURE]`, `[TASK]`, `[BUGFIX]` OR `[CLEANUP]`. This makes it faster to see
+what a commit is about.
+
+## Creating pull requests (PRs)
+
+When you create a pull request, please
+[make your PR editable](https://github.com/blog/2247-improving-collaboration-with-forks).
+
+## Rebasing
+
+If other PRs have been merged during the time between your initial PR creation
+and final approval, it may be required that you rebase your changes against the
+latest `main` branch.
+
+There are potential pitfalls here if you follow the suggestions from `git`,
+which could leave your branch in an unrecoverable mess,
+and you having to start over with a new branch and new PR.
+
+The procedure below is tried and tested, and will help you avoid frustration.
+
+To rebase a feature branch to the latest `main`:
+
+1. Make sure that your local copy of the repository has the most up-to-date
+ revisions of `main` (this is important, otherwise you may end up rebasing to
+ an older base point):
+ ```bash
+ git switch main
+ git pull
+ ```
+1. Switch to the (feature) branch to be rebased and make sure your copy is up to
+ date:
+ ```bash
+ git switch feature/something-cool
+ git pull
+ ```
+1. Consider taking a copy of the folder tree at this stage; this may help when
+ resolving conflicts in the next step.
+1. Begin the rebasing process
+ ```bash
+ git rebase main
+ ```
+1. Resolve the conflicts in the reported files. (This will typically require
+ reversing the order of the new entries in `CHANGELOG.md`.) You may use a
+ folder `diff` against the copy taken at step 3 to assist, but bear in mind
+ that at this stage `git` is partway through rebasing, so some files will have
+ been merged and include the latest changes from `main`, whilst others might
+ not. In any case, you should ignore changes to files not reported as having
+ conflicts.
+
+ If there were no conflicts, skip this and the next step.
+1. Mark the conflicting files as resolved and continue the rebase
+ ```bash
+ git add .
+ git rebase --continue
+ ```
+ (You can alternatively use more specific wildcards or specify individual
+ files with a full relative path.)
+
+ If there were no conflicts reported in the previous step, skip this step.
+
+ If there are more conflicts to resolve, repeat the previous step then this
+ step again.
+1. Force-push the rebased (feature) branch to the remote repository
+ ```bash
+ git push --force
+ ```
+ The `--force` option is important. Without it, you'll get an error with a
+ hint suggesting a `git pull` is required:
+ ```
+ hint: Updates were rejected because the tip of your current branch is behind
+ hint: its remote counterpart. Integrate the remote changes (e.g.
+ hint: 'git pull ...') before pushing again.
+ hint: See the 'Note about fast-forwards' in 'git push --help' for details.
+ ```
+ ***DO NOT*** follow the hint and execute `git pull`. This will result in the
+ set of all commits on the feature branch being duplicated, and the "patching
+ base" not being moved at all.

-PHP CSS Parser
---------------
+# PHP CSS Parser
+
+[](https://github.com/MyIntervals/PHP-CSS-Parser/actions/)
+[](https://coveralls.io/github/MyIntervals/PHP-CSS-Parser?branch=main)
A Parser for CSS Files written in PHP. Allows extraction of CSS files into a data structure, manipulation of said structure and output as (optimized) CSS.
## Usage
-### Installation using composer
-
-Add php-css-parser to your composer.json
+### Installation using Composer
- {
- "require": {
- "sabberworm/php-css-parser": "*"
- }
- }
+```bash
+composer require sabberworm/php-css-parser
+```
### Extraction
To use the CSS Parser, create a new instance. The constructor takes the following form:
- new Sabberworm\CSS\Parser($sText, $sDefaultCharset = 'utf-8');
-
-The charset is used only if no @charset declaration is found in the CSS file.
+```php
+new \Sabberworm\CSS\Parser($css);
+```
To read a file, for example, you’d do the following:
- $oCssParser = new Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
- $oCssDocument = $oCssParser->parse();
+```php
+$parser = new \Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
+$cssDocument = $parser->parse();
+```
The resulting CSS document structure can be manipulated prior to being output.
+### Options
+
+#### Charset
+
+The charset option will only be used if the CSS file does not contain an `@charset` declaration. UTF-8 is the default, so you won’t have to create a settings object at all if you don’t intend to change that.
+
+```php
+$settings = \Sabberworm\CSS\Settings::create()
+ ->withDefaultCharset('windows-1252');
+$parser = new \Sabberworm\CSS\Parser($css, $settings);
+```
+
+#### Strict parsing
+
+To have the parser throw an exception when encountering invalid/unknown constructs (as opposed to trying to ignore them and carry on parsing), supply a thusly configured `\Sabberworm\CSS\Settings` object:
+
+```php
+$parser = new \Sabberworm\CSS\Parser(
+ file_get_contents('somefile.css'),
+ \Sabberworm\CSS\Settings::create()->beStrict()
+);
+```
+
+Note that this will also disable a workaround for parsing the unquoted variant of the legacy IE-specific `filter` rule.
+
+#### Disable multibyte functions
+
+To achieve faster parsing, you can choose to have PHP-CSS-Parser use regular string functions instead of `mb_*` functions. This should work fine in most cases, even for UTF-8 files, as all the multibyte characters are in string literals. Still it’s not recommended using this with input you have no control over as it’s not thoroughly covered by test cases.
+
+```php
+$settings = \Sabberworm\CSS\Settings::create()->withMultibyteSupport(false);
+$parser = new \Sabberworm\CSS\Parser($css, $settings);
+```
+
### Manipulation
-The resulting data structure consists mainly of five basic types: `CSSList`, `RuleSet`, `Rule`, `Selector` and `Value`. There are two additional types used: `Import` and `Charset` which you won’t use often.

#### CSSList
-`CSSList` represents a generic CSS container, most likely containing declaration blocks (rule sets with a selector) but it may also contain at-rules, charset declarations, etc. `CSSList` has the following concrete subtypes:
+`CSSList` represents a generic CSS container, most likely containing declaration blocks (rule sets with a selector), but it may also contain at-rules, charset declarations, etc.
-* `Document` – representing the root of a CSS file.
-* `MediaQuery` – represents a subsection of a CSSList that only applies to a output device matching the contained media query.
+To access the items stored in a `CSSList` – like the document you got back when calling `$parser->parse()` –, use `getContents()`, then iterate over that collection and use `instanceof` to check whether you’re dealing with another `CSSList`, a `RuleSet`, a `Import` or a `Charset`.
+
+To append a new item (selector, media query, etc.) to an existing `CSSList`, construct it using the constructor for this class and use the `append($oItem)` method.
#### RuleSet
`RuleSet` is a container for individual rules. The most common form of a rule set is one constrained by a selector. The following concrete subtypes exist:
-* `AtRule` – for generic at-rules which do not match the ones specifically mentioned like @import, @charset or @media. A common example for this is @font-face.
-* `DeclarationBlock` – a RuleSet constrained by a `Selector`; contains an array of selector objects (comma-separated in the CSS) as well as the rules to be applied to the matching elements.
+* `AtRuleSet` – for generic at-rules for generic at-rules which are not covered by specific classes, i.e., not `@import`, `@charset` or `@media`. A common example for this is `@font-face`.
+* `DeclarationBlock` – a `RuleSet` constrained by a `Selector`; contains an array of selector objects (comma-separated in the CSS) as well as the rules to be applied to the matching elements.
-Note: A `CSSList` can contain other `CSSList`s (and `Import`s as well as a `Charset`) while a `RuleSet` can only contain `Rule`s.
+Note: A `CSSList` can contain other `CSSList`s (and `Import`s as well as a `Charset`), while a `RuleSet` can only contain `Rule`s.
+
+If you want to manipulate a `RuleSet`, use the methods `addRule(Rule $rule)`, `getRules()` and `removeRule($rule)` (which accepts either a `Rule` or a rule name; optionally suffixed by a dash to remove all related rules).
#### Rule
-`Rule`s just have a key (the rule) and a value. These values are all instances of a `Value`.

+`Value` is an abstract class that only defines the `render` method. The concrete subclasses for atomic value types are:
* `Size` – consists of a numeric `size` value and a unit.
-* `Color` – colors can be input in the form #rrggbb, #rgb or schema(val1, val2, …) but are alwas stored as an array of ('s' => val1, 'c' => val2, 'h' => val3, …) and output in the second form.
-* `String` – this is just a wrapper for quoted strings to distinguish them from keywords; always output with double quotes.
-* `URL` – URLs in CSS; always output in URL("") notation.
-
-There is another abstract subclass of `Value`, `ValueList`. A `ValueList` represents a lists of `Value`s, separated by some separation character (mostly `,`, whitespace, or `/`). There are two types of `ValueList`s:
+* `Color` – colors can be input in the form #rrggbb, #rgb or schema(val1, val2, …) but are always stored as an array of ('s' => val1, 'c' => val2, 'h' => val3, …) and output in the second form.
+* `CSSString` – this is just a wrapper for quoted strings to distinguish them from keywords; always output with double quotes.
+* `URL` – URLs in CSS; always output in `URL("")` notation.
-* `RuleValueList` – The default type, used to represent all multi-valued rules like `font: bold 12px/3 Helvetica, Verdana, sans-serif;` (where the value would be a whitespace-separated list of the primitive value `bold`, a slash-separated list and a comma-separated list).
-* `CSSFunction` – A special kind of value that also contains a function name and where the values are the function’s arguments. Also handles equals-sign-separated argument lists like `filter: alpha(opacity=90);`.

+## To-Do
+
+* More convenience methods (like `selectorsWithElement($sId/Class/TagName)`, `attributesOfType($type)`, `removeAttributesOfType($type)`)
+* Real multibyte support. Currently, only multibyte charsets whose first 255 code points take up only one byte and are identical with ASCII are supported (yes, UTF-8 fits this description).
+* Named color support (using `Color` instead of an anonymous string literal)
+
+## Use cases
+
+### Use `Parser` to prepend an ID to all selectors
+
+```php
+$myId = "#my_id";
+$parser = new \Sabberworm\CSS\Parser($css);
+$cssDocument = $parser->parse();
+foreach ($cssDocument->getAllDeclarationBlocks() as $block) {
+ foreach ($block->getSelectors() as $selector) {
+ // Loop over all selector parts (the comma-separated strings in a
+ // selector) and prepend the ID.
+ $selector->setSelector($myId.' '.$selector->getSelector());
+ }
+}
+```
+
+### Shrink all absolute sizes to half
+
+```php
+$parser = new \Sabberworm\CSS\Parser($css);
+$cssDocument = $parser->parse();
+foreach ($cssDocument->getAllValues() as $value) {
+ if ($value instanceof CSSSize && !$value->isRelative()) {
+ $value->setSize($value->getSize() / 2);
+ }
+}
+```
+
+### Remove unwanted rules
+
+```php
+$parser = new \Sabberworm\CSS\Parser($css);
+$cssDocument = $parser->parse();
+foreach($cssDocument->getAllRuleSets() as $oRuleSet) {
+ // Note that the added dash will make this remove all rules starting with
+ // `font-` (like `font-size`, `font-weight`, etc.) as well as a potential
+ // `font` rule.
+ $oRuleSet->removeRule('font-');
+ $oRuleSet->removeRule('cursor');
+}
+```
### Output
-To output the entire CSS document into a variable, just use `->__toString()`:
+To output the entire CSS document into a variable, just use `->render()`:
+
+```php
+$parser = new \Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
+$cssDocument = $parser->parse();
+print $cssDocument->render();
+```
+
+If you want to format the output, pass an instance of type `\Sabberworm\CSS\OutputFormat`:
+
+```php
+$format = \Sabberworm\CSS\OutputFormat::create()
+ ->indentWithSpaces(4)->setSpaceBetweenRules("\n");
+print $cssDocument->render($format);
+```
- $oCssParser = new Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
- $oCssDocument = $oCssParser->parse();
- print $oCssDocument->__toString();
+Or use one of the predefined formats:
+
+```php
+print $cssDocument->render(Sabberworm\CSS\OutputFormat::createPretty());
+print $cssDocument->render(Sabberworm\CSS\OutputFormat::createCompact());
+```
+
+To see what you can do with output formatting, look at the tests in `tests/OutputFormatTest.php`.

+# API and Deprecation Policy
+
+## API Policy
+
+The code in this library is intended to be called by other projects. It is not
+intended to be extended. If you want to extend any classes, you're on your own,
+and your code might break with any new release of this library.
+
+Any classes, methods and properties that are `public` and not marked as
+`@internal` are considered to be part of the API. Those methods will continue
+working in a compatible way over minor and bug-fix releases according
+to [Semantic Versioning](https://semver.org/), though we might change the native
+type declarations in a way that could break subclasses.
+
+Any classes, methods and properties that are `protected` or `private` are _not_
+considered part of the API. Please do not rely on them. If you do, you're on
+your own.
+
+Any code that is marked as `@internal` is subject to change or removal without
+notice. Please do not call it. There be dragons.
+
+If a class is marked as `@internal`, all properties and methods of this class
+are by definition considered to be internal as well.
+
+When we change some code from public to `@internal` in a release, the first
+release that might change that code in a breaking way will be the next major
+release after that. This will allow you to change your code accordingly. We'll
+also add since which version the code is internal.
+
+For example, we might mark some code as `@internal` in version 8.7.0. The first
+version that possibly changes this code in a breaking way will then be version
+9.0.0.
+
+Before you upgrade your code to the next major version of this library, please
+update to the latest release of the previous major version and make sure that
+your code does not reference any code that is marked as `@internal`.
+
+## Deprecation Policy
+
+Code that we plan to remove is marked as `@deprecated`. In the corresponding
+annotation, we also note in which release the code will be removed.
+
+When we mark some code as `@deprecated` in a release, we'll usually remove it in
+the next major release. We'll also add since which version the code is
+deprecated.
+
+For example, when we mark some code as `@deprecated` in version 8.7.0, we'll
+remove it in version 9.0.0 (or sometimes a later major release).
+
+Before you upgrade your code to the next major version of this library, please
+update to the latest release of the previous major version and make sure that
+your code does not reference any code that is marked as `@deprecated`.

+# Steps to release a new version
+
+1. In the [composer.json](../composer.json), update the `branch-alias` entry to
+ point to the release _after_ the upcoming release.
+1. In the [CHANGELOG.md](../CHANGELOG.md), create a new section with subheadings
+ for changes _after_ the upcoming release, set the version number for the
+ upcoming release, and remove any empty sections.
+1. Update the target milestone in the Dependabot configuration.
+1. Create a pull request "Prepare release of version x.y.z" with those changes.
+1. Have the pull request reviewed and merged.
+1. Tag the new release.
+1. In the
+ [Releases tab](https://github.com/MyIntervals/PHP-CSS-Parser/releases),
+ create a new release and copy the change log entries to the new release.
+1. Post about the new release on social media.
