+# Revision History
+
+## 8.0
+
+### 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`.
+
+### 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*
+
+### 8.2.0 (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*
+
+### 8.3.0 (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*
+
+## 7.0
+
+### 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`.
+
+### 7.0.1 (2015-12-25)
+
+* No more suppressed `E_NOTICE`
+* *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*
+
+### 7.0.3 (2016-04-27)
+
+* Fixed parsing empty CSS when multibyte is off
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+## 6.0
+
+### 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)
+
+### 6.0.1 (2015-08-24)
+
+* Remove some declarations in interfaces incompatible with PHP 5.3 (< 5.3.9)
+* *No deprecations*
+
+## 5.0
+
+### 5.0.0 (2013-03-20)
+
+* Correctly parse all known CSS 3 units (including Hz and kHz).
+* Output RGB colors in short (#aaa or #ababab) notation
+* Be case-insensitive when parsing identifiers.
+* *No deprecations*
+
+#### Backwards-incompatible changes
+
+* `Sabberworm\CSS\Value\Color`’s `__toString` method overrides `CSSList`’s to maybe return something other than `type(value, …)` (see above).
+
+### 5.0.1 (2013-03-20)
+
+* Internal cleanup
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 5.0.2 (2013-03-21)
+
+* CHANGELOG.md file added to distribution
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 5.0.3 (2013-03-21)
+
+* More size units recognized
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 5.0.4 (2013-03-21)
+
+* Don’t output floats with locale-aware separator chars
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 5.0.5 (2013-04-17)
+
+* Initial support for lenient parsing (setting this parser option will catch some exceptions internally and recover the parser’s state as neatly as possible).
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 5.0.6 (2013-05-31)
+
+* Fix broken unit test
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 5.0.7 (2013-08-04)
+
+* Fix broken decimal point output optimization
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 5.0.8 (2013-08-15)
+
+* Make default settings’ multibyte parsing option dependent on whether or not the mbstring extension is actually installed.
+* *No backwards-incompatible changes*
+* *No deprecations*
+
+### 5.1.0 (2013-10-24)
+
+* Performance enhancements by Michael M Slusarz
+* More rescue entry points for lenient parsing (unexpected tokens between declaration blocks and unclosed comments)
+* *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*
+
+### 5.1.2 (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*
+
+### 5.2.0 (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.
+
+## 4.0
+
+### 4.0.0 (2013-03-19)
+
+* Support for more @-rules
+* Generic interface `Sabberworm\CSS\Property\AtRule`, implemented by all @-rule classes
+* *No deprecations*
+
+#### Backwards-incompatible changes
+
+* `Sabberworm\CSS\RuleSet\AtRule` renamed to `Sabberworm\CSS\RuleSet\AtRuleSet`
+* `Sabberworm\CSS\CSSList\MediaQuery` renamed to `Sabberworm\CSS\RuleSet\CSSList\AtRuleBlockList` with differing semantics and API (which also works for other block-list-based @-rules like `@supports`).
+
+## 3.0
+
+### 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
+
+### 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.

+PHP CSS Parser
+--------------
+
+[](https://travis-ci.org/sabberworm/PHP-CSS-Parser) [](http://hhvm.h4cc.de/package/sabberworm/php-css-parser)
+
+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
+
+```json
+{
+ "require": {
+ "sabberworm/php-css-parser": "*"
+ }
+}
+```
+
+### Extraction
+
+To use the CSS Parser, create a new instance. The constructor takes the following form:
+
+```php
+new Sabberworm\CSS\Parser($sText);
+```
+
+To read a file, for example, you’d do the following:
+
+```php
+$oCssParser = new Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
+$oCssDocument = $oCssParser->parse();
+```
+
+The resulting CSS document structure can be manipulated prior to being output.
+
+### Options
+
+#### Charset
+
+The charset option is used only if no @charset declaration is found in the CSS file. UTF-8 is the default, so you won’t have to create a settings object at all if you don’t intend to change that.
+
+```php
+$oSettings = Sabberworm\CSS\Settings::create()->withDefaultCharset('windows-1252');
+new Sabberworm\CSS\Parser($sText, $oSettings);
+```
+
+#### Strict parsing
+
+To have the parser choke on invalid rules, supply a thusly configured Sabberworm\CSS\Settings object:
+
+```php
+$oCssParser = new Sabberworm\CSS\Parser(file_get_contents('somefile.css'), Sabberworm\CSS\Settings::create()->beStrict());
+```
+
+#### 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 to use this with input you have no control over as it’s not thoroughly covered by test cases.
+
+```php
+$oSettings = Sabberworm\CSS\Settings::create()->withMultibyteSupport(false);
+new Sabberworm\CSS\Parser($sText, $oSettings);
+```
+
+### Manipulation
+
+The resulting data structure consists mainly of five basic types: `CSSList`, `RuleSet`, `Rule`, `Selector` and `Value`. There are two additional types used: `Import` and `Charset` which you won’t use often.
+
+#### CSSList
+
+`CSSList` represents a generic CSS container, most likely containing declaration blocks (rule sets with a selector) but it may also contain at-rules, charset declarations, etc. `CSSList` has the following concrete subtypes:
+
+* `Document` – representing the root of a CSS file.
+* `MediaQuery` – represents a subsection of a CSSList that only applies to a output device matching the contained media query.
+
+To access the items stored in a `CSSList` – like the document you got back when calling `$oCssParser->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:
+
+* `AtRuleSet` – 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.
+
+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 $oRule)`, `getRules()` and `removeRule($mRule)` (which accepts either a Rule instance 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
+
+`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 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.
+
+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:
+
+* `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);`.
+
+#### Convenience methods
+
+There are a few convenience methods on Document to ease finding, manipulating and deleting rules:
+
+* `getAllDeclarationBlocks()` – does what it says; no matter how deeply nested your selectors are. Aliased as `getAllSelectors()`.
+* `getAllRuleSets()` – does what it says; no matter how deeply nested your rule sets are.
+* `getAllValues()` – finds all `Value` objects inside `Rule`s.
+
+## To-Do
+
+* More convenience methods [like `selectorsWithElement($sId/Class/TagName)`, `attributesOfType($sType)`, `removeAttributesOfType($sType)`]
+* Real multibyte support. Currently only multibyte charsets whose first 255 code points take up only one byte and are identical with ASCII are supported (yes, UTF-8 fits this description).
+* Named color support (using `Color` instead of an anonymous string literal)
+
+## Use cases
+
+### Use `Parser` to prepend an id to all selectors
+
+```php
+$sMyId = "#my_id";
+$oParser = new Sabberworm\CSS\Parser($sText);
+$oCss = $oParser->parse();
+foreach($oCss->getAllDeclarationBlocks() as $oBlock) {
+ foreach($oBlock->getSelectors() as $oSelector) {
+ //Loop over all selector parts (the comma-separated strings in a selector) and prepend the id
+ $oSelector->setSelector($sMyId.' '.$oSelector->getSelector());
+ }
+}
+```
+
+### Shrink all absolute sizes to half
+
+```php
+$oParser = new Sabberworm\CSS\Parser($sText);
+$oCss = $oParser->parse();
+foreach($oCss->getAllValues() as $mValue) {
+ if($mValue instanceof CSSSize && !$mValue->isRelative()) {
+ $mValue->setSize($mValue->getSize()/2);
+ }
+}
+```
+
+### Remove unwanted rules
+
+```php
+$oParser = new Sabberworm\CSS\Parser($sText);
+$oCss = $oParser->parse();
+foreach($oCss->getAllRuleSets() as $oRuleSet) {
+ $oRuleSet->removeRule('font-'); //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
+ $oRuleSet->removeRule('cursor');
+}
+```
+
+### Output
+
+To output the entire CSS document into a variable, just use `->render()`:
+
+```php
+$oCssParser = new Sabberworm\CSS\Parser(file_get_contents('somefile.css'));
+$oCssDocument = $oCssParser->parse();
+print $oCssDocument->render();
+```
+
+If you want to format the output, pass an instance of type `Sabberworm\CSS\OutputFormat`:
+
+```php
+$oFormat = Sabberworm\CSS\OutputFormat::create()->indentWithSpaces(4)->setSpaceBetweenRules("\n");
+print $oCssDocument->render($oFormat);
+```
+
+Or use one of the predefined formats:
+
+```php
+print $oCssDocument->render(Sabberworm\CSS\OutputFormat::createPretty());
+print $oCssDocument->render(Sabberworm\CSS\OutputFormat::createCompact());
+```
+
+To see what you can do with output formatting, look at the tests in `tests/Sabberworm/CSS/OutputFormatTest.php`.
