import java.util.stream.IntStream;

public class Main {

    public static void main(String[] args) throws URISyntaxException {

        PatternData patternData = RleParser.readPatternData(Main.class.getClassLoader().getResource("glider.rle").toURI());

        System.out.println(IntStream.range(0, patternData.getMetaData().getHeight())

                .mapToObj(patternData.getLiveCells()::filteredByY)

                .map(filteredByY -> IntStream.range(0, patternData.getMetaData().getWidth())

                        .mapToObj(filteredByY::filteredByX)

                        .map(LiveCells::getCoordinates)

                        .map(coordinates -> coordinates.size() == 0 ? "." : "@")

                        .collect(Collectors.joining()))

                .collect(Collectors.joining("\n")));
