## Recap { #recap }

Apart from all the fancy words used here, the **Dependency Injection** system is quite simple.

Just functions that look the same as the *path operation functions*.

{* ../../docs_src/metadata/tutorial004_py39.py hl[3:16,18] *}

Помните, что вы можете использовать Markdown внутри описания, к примеру "login" будет отображен жирным шрифтом (**login**) и "fancy" будет отображаться курсивом (_fancy_).

/// tip | Подсказка

Вам необязательно добавлять метаданные для всех используемых тегов

///

### Используйте собственные теги { #use-your-tags }

            } else {
                this.host = remaining.substring(0, slashIndex);
                this.path = remaining.substring(slashIndex);
            }

            // canonical form: remove . and .. but nothing fancy
            this.canonical = urlStr.replace("..", "").replace(".", "");
        }

        @Override
        public String getName() {
            if (path == null || path.isEmpty() || path.equals("/")) {

{* ../../docs_src/metadata/tutorial004_py39.py hl[3:16,18] *}

Notice that you can use Markdown inside of the descriptions, for example "login" will be shown in bold (**login**) and "fancy" will be shown in italics (_fancy_).

/// tip

You don't have to add metadata for all the tags that you use.

///

### Use your tags { #use-your-tags }

Then it's your turn, you place your order of 2 very fancy burgers for your crush and you. 🍔🍔

{* ../../docs_src/metadata/tutorial004_py39.py hl[3:16,18] *}

Beachten Sie, dass Sie Markdown innerhalb der Beschreibungen verwenden können. Zum Beispiel wird „login“ in Fettschrift (**login**) und „fancy“ in Kursivschrift (_fancy_) angezeigt.

/// tip | Tipp

Sie müssen nicht für alle von Ihnen verwendeten Tags Metadaten hinzufügen.

///

### Ihre Tags verwenden { #use-your-tags }

{* ../../docs_src/metadata/tutorial004_py39.py hl[3:16,18] *}

Nota que puedes utilizar Markdown dentro de las descripciones, por ejemplo "login" se mostrará en negrita (**login**) y "fancy" se mostrará en cursiva (_fancy_).

/// tip | Consejo

No tienes que agregar metadata para todas las etiquetas que uses.

///

### Usar tus etiquetas { #use-your-tags }

{* ../../docs_src/metadata/tutorial004_py39.py hl[3:16,18] *}

Observe que você pode usar Markdown dentro das descrições. Por exemplo, "login" será exibido em negrito (**login**) e "fancy" será exibido em itálico (_fancy_).

/// tip | Dica

Você não precisa adicionar metadados para todas as tags que você usa.
