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.

  • 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.

  • Fixed parsing empty CSS when multibyte is off
  • No backwards-incompatible changes
  • No deprecations

7.0.2 (2016-02-11)

  • 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

  • No backwards-incompatible changes
  • No deprecations

5.0.6 (2013-05-31)

  • Fix broken unit test
  • 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

5.0.4 (2013-03-21)

  • Don’t output floats with locale-aware separator chars

  • No backwards-incompatible changes
  • No deprecations

5.0.2 (2013-03-21)

  • CHANGELOG.md file added to distribution
  • No backwards-incompatible changes
  • No deprecations

5.0.1 (2013-03-20)

  • Internal cleanup
  • No backwards-incompatible changes
  • No deprecations

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).

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).

3.0.0 (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
