Implementation

@override
JinjaValue execute(Context ctx) {
  if (name is! Identifier) {
    throw Exception('Macro name must be identifier');
  }
  final macroName = (name as Identifier).name;

  final func = JinjaFunction(macroName, (callArgs, callKwargs) {
    // Create macro context
    final macroCtx = ctx.derive();

    _bindParameters(macroName, args, callArgs, callKwargs, macroCtx, ctx);

    // Inject 'caller' if present in kwargs (from {% call %})
    if (callKwargs.containsKey('caller')) {
      macroCtx.set('caller', callKwargs['caller']!);
    }

    return _execCaptured(body, macroCtx);
  });

  ctx.set(macroName, func);
  return const JinjaNone();
