wrapper<L, R> method

void wrapper<L, R>(
  1. Parser<L> left,
  2. Parser<R> right,
  3. T callback(
    1. L left,
    2. T value,
    3. R right
    )
)

Defines a new wrapper using left and right parsers, that are typically used for parentheses.

Evaluates the callback with the parsed left delimiter, the value, and right delimiter.

Implementation

void wrapper<L, R>(
  Parser<L> left,
  Parser<R> right,
  T Function(L left, T value, R right) callback,
) => _wrapper.add(seq3(left, _loopback, right).map3(callback));
