import "package:template_block/template_block.dart";

void main() {
  var statement = TemplateBlock(_templateStatement);
  statement.assign("MIN", 0);
  statement.assign("MAX", 128);
  var methodFoo = TemplateBlock(_templateMethodFoo);
  methodFoo.assign("#STATEMENTS", statement.process());
  statement = statement.clone();
  statement.assign("MIN", 512);
  statement.assign("MAX", 1024);
  methodFoo.assign("#STATEMENTS", statement.process());
  var methodBaz = TemplateBlock(_templateMethodBaz);
  var clazz = TemplateBlock(_templateClass);
  clazz.assign("NAME", "MyClass");
  clazz.assign("#METHODS", methodBaz.process());
  clazz.assign("#METHODS", methodFoo.process());
  var library = TemplateBlock(_templateLibraryPart);
  library.assign("NAME", "my_lib");
  library.assign("#CLASSES", clazz.process());
  print(library.process().join("\n"));
