Contract

  1. plugin exports a Babel plugin declaration function
  2. plugin returns a plugin object with name transform-dotall-regex and RegExpLiteral visitor
  3. plugin transforms dotAll regex literal with s flag to equivalent character class matching newlines and removes s flag
  4. plugin preserves other regex flags like global, ignoreCase, multiline, and unicode while removing s flag
  5. plugin transforms dot inside complex patterns and quantifiers while leaving literal dots in character classes untouched
  6. plugin leaves regular expressions without s flag unchanged
  7. transformed regular expressions match newline characters and multiline text correctly at runtime
