Правила основаны на эмпирическом анализе страницы, опубликованной с помощью скрипта `scripts/research_anchors.ts`. **Этот документ заменяет все предыдущие версии и предположения.** --- #### **Точный алгоритм** 1. **Исходный текст:** Берется полный текст заголовка "как есть" (`as-is`), включая все символы Markdown-форматирования (`*`, `_`, `[`, `]`, `(`, `)`, `` ` ``). 2. **Очистка пробелов:** Удаляются начальные и конечные пробелы (`trim`). 3. **Удаление символов:** Из текста удаляются **только** символы угловых скобок (`<` и `>`). 4. **Замена пробелов:** Все символы пробела (` `) заменяются на дефисы (`-`). 5. **Сохранение остального:** Все остальные символы, включая кириллицу, знаки препинания, спецсимволы и символы Markdown, **остаются без изменений**. Регистр символов **сохраняется**. --- #### **Примеры преобразования** | Исходный текст заголовка | Сгенерированный якорь | Примечание | | :--- | :--- | :--- | | `Title With Spaces` | `Title-With-Spaces` | Пробелы заменены, регистр сохранен. | | `Заголовок с пробелами` | `Заголовок-с-пробелами` | Кириллица и регистр сохраняются. | | `**Bold Title**` | `**Bold-Title**` | Символы Markdown (`**`) **не** удаляются. | | `[Link Title](url)` | `[Link-Title](url)` | Символы ссылки **не** удаляются. | | `Title with < > symbols` | `Title-with--symbols` | Символы `<` и `>` были удалены. | | `Аналогия «Дерево цивилизации» (из комментария к ШБ 1.1.4)` | `Аналогия-«Дерево-цивилизации»-(из-комментария-к-ШБ-1.1.4)` | Сложные знаки препинания сохраняются. | --- #### **Ключевые принципы** * **Регистр сохраняется.** (`Case-Sensitive`) * **Markdown-форматирование НЕ удаляется.** * **Только пробелы заменяются на дефисы.** * **Почти все спецсимволы сохраняются,** за исключением `<` и `>`. --- #### **Псевдокод для реализации** ```javascript function generateTelegraphAnchor(headerText: string): string { // 1. Взять исходный текст и очистить пробелы по краям let anchor = headerText.trim(); // 2. Удалить символы < и > anchor = anchor.replace(/[<>]/g, ''); // 3. Заменить все пробелы на дефисы anchor = anchor.replace(/ /g, '-'); // 4. Вернуть результат. Никаких других преобразований не требуется. return anchor; } ``` Этот алгоритм должен быть реализован в `LinkVerifier.ts` и `markdownConverter.ts` для обеспечения консистентности при валидации ссылок и генерации оглавления. ``` `src/doc/api.md` ```md --- title: Telegraph API description: >- Telegra.ph is a minimalist publishing tool that allows you to create richly formatted posts and push them to the Web in just a click.

To maintain the purity of the basic interface, we launched the [**@Telegraph**](https://telegram.me/telegraph) **bot** for those who require advanced features. This bot can help you manage your articles across any number of devices and get page view statistics for any Telegraph page. Anyone can enjoy the simplicity of Telegraph publishing, not just [Telegram](https://telegram.org/) users. For this reason, all developers are welcome to use this **Telegraph API** to create bots like [@Telegraph](https://telegram.me/telegraph) for any other platform, or even standalone interfaces. All queries to the Telegraph API must be served over **HTTPS** and should be presented in this form: `https://api.telegra.ph/%method%`. If a `path` parameter is present, you can also use this form: `https://api.telegra.ph/%method%/%path%`. #### [1\. Methods](#Available-methods) - [Telegraph API](#telegraph-api) - [1.

Content format](#Content-format) ### ### Available methods We support **GET** and **POST** HTTP methods. The response contains a JSON object, which always has a Boolean field `ok`. If `ok` equals _true_, the request was successful, and the result of the query can be found in the `result` field. In case of an unsuccessful request, `ok` equals _false,_ and the error is explained in the `error` field (e.g. SHORT\_NAME\_REQUIRED). All queries must be made using UTF-8. #### createAccount Use this method to create a new Telegraph account. Most users only need one account, but this can be useful for channel administrators who would like to keep individual author names and profile links for each of their channels.

}   var nodeElement = {};   nodeElement.tag = domNode.tagName.toLowerCase();   for (var i = 0; i < domNode.attributes.length; i++) {    var attr = domNode.attributes\[i\];    if (attr.name == 'href' || attr.name == 'src') {     if (!nodeElement.attrs) {      nodeElement.attrs = {};

    nodeElement.children.push(domToNode(child));   }   }   return nodeElement; } function nodeToDom(node) { if (typeof node === 'string' || node instanceof String) {   return document.createTextNode(node); } if (node.tag) {   var domNode = document.createElement(node.tag);   if (node.attrs) {     for (var name in node.attrs) {     var value = node.attrs\[name\];     domNode.setAttribute(name, value);   }   } } else {   var domNode = document.createDocumentFragment(); }   if (node.children) {    for (var i = 0; i < node.children.length; i++) {     var child = node.children\[i\];     domNode.appendChild(nodeToDom(child));    }   }   return domNode; } var article = document.getElementById('article');
