Changelog

Source

1.0.0-alpha15 (February 8, 2017)

  • Fixed broken atruleExpression context
  • Fixed vendor prefix detection in keyword() and property()
  • Fixed property() to not lowercase custom property names
  • Added variable boolean flag in property() result
  • Renamed scanner into tokenizer
  • Ranamed syntax into lexer
  • Moved docs/*.html files to csstree/docs repo
  • Added element() function for Value context (-moz-element() supported as well)
  • Merged Universal node type into Type
  • Renamed node types:
    • Id -> IdSelector
    • Class -> ClassSelector
    • Type -> TypeSelector
    • Attribute -> AttributeSelector
    • PseudoClass -> PseudoClassSelector
    • PseudoElement -> PseudoElementSelector
    • Hash -> HexColor
    • Space -> WhiteSpace
    • An+B -> AnPlusB
  • Removed Progid node type
  • Relaxed MediaQuery consumer to not validate syntax on parse and to include whitespaces in children sequence as is
  • Added WhiteSpace.value property to store whitespace sequence
  • Implemented parser options to specify what should be parsed in details (when option is false some part of CSS represents as balanced Raw):
    • parseAtruleExpression – to parse at-rule expressions (true by default)
    • parseSelector – to parse rule's selector (true by default)
    • parseValue - to parse declaration's value (true by default)
    • parseCustomProperty – to parse value and fallback of custom property (false by default)
  • Changed tokenization to stick leading hyphen minus to identifier token
  • Changed selector parsing:
    • Don't convert spaces into descendant combinator
    • Don't validate selector structure on parsing (selectors may be checked by lexer later)
  • Initial refactoring of docs
  • Various improvements and fixes

Changelog

Source

1.0.0-alpha14 (February 3, 2017)

  • Implemented DeclarationList, MediaQueryList, MediaQuery, MediaFeature and Ratio node types
  • Implemented declarationList context (useful to parse HTML style attribute content)
  • Implemented custom consumers for @import, @media, @page and @supports at-rules
  • Implemented atrule option for parse() config, is used for atruleExpession context to specify custom consumer for at-rule if any
  • Added Scanner#skipWS(), Scanner#eatNonWS(), Scanner#consume() and Scanner#consumeNonWS() helper methods
  • Added custom consumers for known functional-pseudos, consume unknown functional-pseudo content as balanced Raw
  • Allowed any PseudoElement to be a functional-pseudo (#33)
  • Improved walker implementations to reduce GC thrashing by reusing cursors
  • Changed Atrule.block to contain a Block node type only if any
  • Changed Block.loc positions to include curly brackets
  • Changed Atrule.expression to store a null if no expression
  • Changed parser to use StyleSheet node type only for top level node (when context is stylesheet, that's by default)
  • Changed Parentheses, Brackets and Function consumers to use passed sequence reader instead of its own
  • Changed Value and AtruleExpression consumers to use common sequence reader (that reader was used by Value consumer before)
  • Changed default sequence reader to exclude storage of spaces around Comma
  • Changed processing of custom properties:
    • Consume declaration value as balanced Raw
    • Consume var() fallback value as balanced Raw
    • Validate first argument of var() starts with double dash
    • Custom property's value and fallback includes spaces around
  • Fixed Nth to have a loc property
  • Fixed SelectorList.loc and Selector.loc positions to exclude spaces
  • Fixed issue Browserify build fail with default-syntax.json is not found error (#32, @philschatz)
  • Disallowed Type selector starting with dash (parser throws an error in this case now)
  • Disallowed empty selectors for Rule (not sure if it's correct but looks reasonable)
  • Removed >> combinator support until any browser support (no signals about that yet)
  • Removed PseudoElement.legacy property
  • Removed special case for :before, :after, :first-letter and :first-line to represent them as PseudoElement, now those pseudos are represented as PseudoClass nodes
  • Removed deprecated Syntax#match() method
  • Parser was splitted into modules and related changes, one step closer to an extensible parser
  • Various fixes and improvements, all changes have negligible impact on performance

Source

1.0.0-alpha8 (November 11, 2016)
