Members

protected

• $blockDirectives
• $commentMulti
• $commentMultiLeft
• $commentMultiRight
• $commentSingle
• $inParens
  if we are in parens we can be more liberal with whitespace around operators because it must evaluate to a single value and thus is less ambiguous.
• $lineDirectives
• $literalCache
• $nextBlockId
• $operatorString
• $precedence
• $supressDivisionProps
• $whitePattern
