tokensToText method

@override String tokensToText(List<String> tokens)

Converts tokens to text.

Implementation

@override
String tokensToText(List<String> tokens) {
  String tokenized = tokens.join(' '); // Joining tokens into a single string

  // Replacing position tokens with 'x' separator
  tokenized = tokenized.replaceAllMapped(RegExp(r'p(\d*) p(\d*)'),
      (match) => '${match.group(1)}x${match.group(2)}');
  // Replacing column and row tokens with simplified format
  tokenized = tokenized.replaceAllMapped(RegExp(r'c(\d)\d? r(.)'),
      (match) => '${match.group(1)}${match.group(2)}');
  // Replacing single-digit columns with two-digit format
  tokenized = tokenized.replaceAllMapped(
      RegExp(r'c(\d)\d?'), (match) => '${match.group(1)} 0');
  // Replacing single-digit rows with two-digit format
  tokenized = tokenized.replaceAllMapped(
      RegExp(r'r(.)'), (match) => '0${match.group(1)}');
  // Removing spaces between digits and box symbols
  tokenized = tokenized.replaceAll(' ', '');
  tokenized = tokenized.replaceAllMapped(
      RegExp(r'(\d)([MBLR])'),
      (match) =>
          '${match.group(1)} ${match.group(2)}'); // Adding space between digit and box symbol

  return tokenized; // Returning the detokenized FSW string
}
