Implementation

String staleIgnoresToJsonString(List<StaleIgnore> staleIgnores) {
  final list = staleIgnores
      .map(
        (s) => <String, Object>{
          'filePath': s.filePath,
          'commentLine': s.commentLine,
          'targetLine': s.targetLine,
          'ruleName': s.ruleName,
          'commentText': s.commentText,
        },
      )
      .toList();

  // Group by file for the summary, same pattern as scan diagnostics.
  final byFile = <String, int>{};
  final byRule = <String, int>{};
  for (final s in staleIgnores) {
    byFile[s.filePath] = (byFile[s.filePath] ?? 0) + 1;
    byRule[s.ruleName] = (byRule[s.ruleName] ?? 0) + 1;
  }

  return const JsonEncoder.withIndent('  ').convert(<String, Object>{
    'version': 1,
    'staleIgnores': list,
    'summary': <String, Object>{
      'totalCount': staleIgnores.length,
      'byFile': byFile,
      'byRule': byRule,
    },
  });
