addTursoReservedDatabase function

String addTursoReservedDatabase(String call, String logicalName)

Adds logicalName to reservedDatabases of a turso.Functions.turso / turso.Functions.tursoToken call call (whose argument is an object literal).

call（引数がオブジェクトリテラルのturso.Functions.turso / turso.Functions.tursoToken呼び出し）のreservedDatabasesにlogicalNameを追加します。

Implementation

String addTursoReservedDatabase(String call, String logicalName) {
  final existing =
      RegExp(r"reservedDatabases\s*:\s*\[([^\]]*)\]").firstMatch(call);
  if (existing != null) {
    final names = RegExp(r'''["']([^"']+)["']''')
        .allMatches(existing.group(1)!)
        .map((match) => match.group(1)!)
        .toList();
    if (names.contains(logicalName)) {
      return call;
    }
    final value = "reservedDatabases: ${jsonEncode([...names, logicalName])}";
    return call.replaceRange(existing.start, existing.end, value);
  }
  if (RegExp(r"\breservedDatabases\b").hasMatch(call)) {
    // A non-literal value is owned by the application.
    return call;
  }
  final open = call.indexOf("(");
  final objectStart = call.indexOf("{", open);
  if (objectStart < 0) {
    return call;
  }
  return call.replaceRange(objectStart + 1, objectStart + 1,
      "\n        reservedDatabases: ${jsonEncode([logicalName])},");
}
