binaryLiteral method

Parser<ConstantNode> binaryLiteral()

Implementation

Parser<ConstantNode> binaryLiteral() =>
    ((string('0b') | string('0B')) &
            (pattern('01') | char('_')).plus().flatten())
        .flatten()
        .map(
          (s) => ConstantNode(
            int.parse(s.substring(2).replaceAll('_', ''), radix: 2),
          ),
        );
