Roadmap 1.0

[lahmatiy]

• move !important from Value to Declaration
• Braces -> Parentheses
• Ruleset -> Rule
• drop Unknown
• replace Identifier -> Type/Universal selector
• FunctionalPseudo -> PseudoClass
• fix attribute name parsing
• add Brackets since CSS Grid Layout introduces it
• at-rule inside block (Support for mixed rules and declarations inside at-rules #24)
• of clause for nth-child/nth-last-child e.g. nth-child(.. of <Selector>)
• check number is integer for
  • UnicodeRange
  • Hash
  • Nth (an+b)
• natural traversal order for walk() (current behaviour should be implemented as walkUp())
• :matches() (Support for CSS Selectors Level 4 #28)
• :has()
• ::slotted()
• rename sequence -> children for node types
• end line/column in node.info
• rename Selector -> SelectorList, SimpleSelector -> Selector
• fix Block positions (should include {})
• fix positions for Selector/SimpleSelector to not include ws
• rename StyleSheet inside at-rule to Block (when at-rule will be allowed inside block)
• add loc to Nth
• use balanced raw consumer for custom properties
• DeclarationList instead of Block and add declarationList context (for <element style=""> context)
• Atrule.expression should be null when no expression
• split parser into modules (one per node type)
• custom parsers for well-known at-rule expressions
• add Selector suffix for Id, Class, Attribute, Type, PseudoClass and PseudoElement
• options to parse Value, Selector and AtruleExpression as balanced Raw (parseValue, parseSelector, parseAtruleExpression)
• option to parse custom property value/fallback as regular value (parseCustomProperty)
• drop Progid
• rename Space to WhiteSpace
• rename Hash to HexColor
• parse unknown parts of Value as balanced Raw

Under consideration:

• Percentage -> Dimension
• multiple Value (no parts comma operator, but list of Value)

  more convenient to work with Value in current form

• explicit descendant combinator >>

  until any browser support

• Column combinator ||

  until any browser support

• convert name node to property in Attribute
  • q: where to store location?
• namespaces for Type/Universal/Attribute (special case for :matches)
  • q: should we need store it separately?
• rename loc -> meta (to store formatting info too)
• rename Block -> {}-block, Parenthesis -> ()-block, Brackets -> []-block according to CSS Syntax Module Level 3 that's for tokens not ast node
• should SelectorList to be omitted when have a single selector?
• replace Rule.block to Rule.children and Atrule.block to Atrule.children

  bad idea, since block includes {} now

• rename positions parse option to loc
• store formatting info somehow
• allow percent in @Keyframes selectors only (from/to/percent) should restrict by lexer not parser
• better name for parse* options looks ok for now
