tokenizeSymbol static method

List<String> tokenizeSymbol(SignSymbol symbol, { bool boxPosition = false, })

Method to tokenize a SignSymbol into a list of tokens.

Implementation

static List<String> tokenizeSymbol(SignSymbol symbol,
    {bool boxPosition = false}) {
  if (['B', 'L', 'M', 'R'].contains(symbol.symbol)) {
    // If the symbol is a box symbol
    List<String> tokens = [symbol.symbol]; // Adding box symbol
    if (boxPosition) {
      tokens.add("p${symbol.position.item1}"); // Adding x-coordinate
      tokens.add("p${symbol.position.item2}"); // Adding y-coordinate
    } else {
      tokens.add("p500"); // Assuming default position of 500x500
      tokens.add("p500"); // Assuming default position of 500x500
    }
    return tokens;
  } else {
    // If the symbol is a base symbol
    List<String> tokens = [
      symbol.symbol.substring(0, 4)
    ]; // Adding base symbol
    int num = int.parse(symbol.symbol.substring(4),
        radix: 16); // Parsing symbol number
    tokens.add("c${(num ~/ 0x10).toRadixString(16)}"); // Adding column
    tokens.add("r${(num % 0x10).toRadixString(16)}"); // Adding row
    tokens.add("p${symbol.position.item1}"); // Adding x-coordinate
    tokens.add("p${symbol.position.item2}"); // Adding y-coordinate
    return tokens;
  }
