makeSquareSet function

SquareSet makeSquareSet(String rep)

Takes a string and returns a SquareSet. Useful for debugging/testing purposes.

Example:

final str = '''
. 1 1 1 . . . .
. 1 . 1 . . . .
. 1 . . 1 . . .
. 1 . . . 1 . .
. 1 1 1 1 . . .
. 1 . . . 1 . .
. 1 . . . 1 . .
. 1 . . 1 . . .
'''
final squareSet = makeSquareSet(str);
// SquareSet(0x0E0A12221E222212)

Implementation

SquareSet makeSquareSet(String rep) {
  SquareSet ret = SquareSet.empty;
  final table = rep
      .split('\n')
      .where((l) => l.isNotEmpty)
      .map((r) => r.split(' '))
      .toList()
      .reversed
      .toList();
  for (int y = 7; y >= 0; y--) {
    for (int x = 0; x < 8; x++) {
      final repSq = table[y][x];
      if (repSq == '1') {
        ret = ret.withSquare(x + y * 8);
      }
    }
  }
  return ret;
