SimpleTag class

A tag simplifies the implementation of simple tags. For example,

import 'package:stream/rspc.dart';

void main(List<String> arguments) {
  tags["m"] = new SimpleTag("m",
    (TagContext tc, String id, Map<String, String> args) {
      if (id == null)
        throw new ArgumentError("id required");
      tc.write("\n${tc.pre}response.write(message(connect, $id");
      if (args != null && args.isNotEmpty) {
        tc.write(", ");
        outMap(tc, args);
      }
      tc.writeln("));");
    });

  build(arguments,
    imports: ["package:foo/server/intl.dart"]);
}
