 # NotEnoughItems Unofficial - By the GTNH Team

+🌐 **Languages:** [English](README.md) | [Українська](README_uk.md)
+
 A continuation of NotEnoughItems for 1.7.10 by the developers of Gregtech: New Horizons modpack, with features either inspired and/or backported from JustEnoughItems

 We've tested this against all of the mods included in GTNH, as well as a limited set of other mods (like Reika's mods). Every effort has been made to maintain backwards compatibility, however the focus is on the mods contained in the GTNH modpack.

+# NotEnoughItems Unofficial — від команди GTNH
+
+🌐 **Мови:** [English](README.md) | [Українська](README_uk.md)
+
+Продовження модифікації NotEnoughItems для 1.7.10 від розробників збірки GregTech: New Horizons із функціями, натхненними та/або бекпортованими з JustEnoughItems.
+
+Ми протестували цю версію з усіма модами, що входять до GTNH, а також із обмеженим набором інших модів (як-от моди від Reika). Було докладено всіх зусиль для збереження зворотної сумісності, однак основну увагу приділено модам зі збірки GTNH.
+
+Якщо у вас виникли проблеми з NEI за межами збірки GTNH, ви можете повідомити про них у [GitHub-репозиторії GTNH NEI](https://github.com/GTNewHorizons/NotEnoughItems).
+
+## Нові можливості:
+
+* Швидкодія
+  - Використовує паралельний потік для пошуку у списку предметів на кількох ядрах процесора, що в середньому пришвидшує пошук у 2–6 разів.
+  - Завантажує обробники рецептів паралельно.
+* Текстове поле пошуку з більшістю очікуваних функцій — переміщення курсора вперед/назад, виділення тексту тощо.
+* Закладки! Перебуваєте у процесі крафту? Додайте потрібний рецепт до закладок за допомогою клавіші «A» або налаштуйте власну клавішу.
+* Перемикання видимості панелі закладок. Гаряча клавіша за замовчуванням — `B`. Меню «Підгрупи предметів» доступне лише тоді, коли панель закладок прихована.
+* Кнопки утиліт та читів вирівнюються в ряд та переносяться на новий рядок залежно від розміру графічного інтерфейсу.
+* Список предметів (`ItemList`) більше не генерується повторно з `ItemRegistry` під час кожного відкриття інвентарю.
+* Вкладки у стилі JEI (або творчого режиму) [За бажанням]. Примітка: вимагає явної підтримки для рендерингу `ItemStack`, інакше використовуються перші дві літери назви обробника.
+* Вкладки/обробники завантажуються з конфігураційного CSV-файлу в JAR-архіві (або за бажанням з папки `config`). Для авторів модів доступні IMC-повідомлення з NBT-даними `registerHandlerInfo` та `removeHandlerInfo` для додавання інформації про обробники з використанням тих самих полів, що й у CSV-файлі.
+* Пошук за допомогою синтаксису `@[Мод]->[предмет]`. Наприклад: `@Mod.gregtech->iron ingot`.
+* Перемикання між режимами рецептів, утиліт та читів за допомогою CTRL + ЛКМ по іконці гайкового ключа.
+* Інструменти/предмети з GT5u та інструменти з GT6 тепер мають коректно працювати з функцією накладення та перенесення рецепта.
+
+### Обробник інформаційних сторінок
+Хочете додати інформацію про блок чи предмет, не створюючи для нього величезну підказку? Ви можете додати інформацію про будь-який блок чи предмет, зареєструвавши його в обробнику інформації.
+
+Інформаційні сторінки відображаються під час пошуку рецептів або способів використання відповідного предмета. Усі відповідні предмети будуть циклічно змінюватися у верхній частині інформаційної сторінки.
+
+Ваш мод може викликати:
+```java
+FMLInterModComms.sendMessage("NotEnoughItems", "addItemInfo", nbt);
+```
+Де `nbt` — це `NBTTagCompound`, відформатований, як описано нижче.
+
+| Тег              | Тип                            | Опис                                                                                                                                                                                                                                                                 |
+|------------------|--------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| `filter`         | `String`                       | Текстовий фільтр для визначення предметів, для яких має відображатися ця інформаційна сторінка.<br/>Можна використовувати `modname:itemname`, метадані, теги OreDictionary та регулярні вирази. Повний формат можна переглянути у `config/NEI/collapsibleitems.cfg`. |
+| `page` / `pages` | `String` / `String NBTTagList` | Безпосередньо текст для відображення. Різницю між одно- та багатосторінковими повідомленнями див. нижче.<br/>Обидва формати підтримують автоматичний переклад наданих рядків.                                                                                        |
+
+#### Односторінковий формат
+
+Використовуйте текстовий тег `"page"`, якщо хочете додати лише одну сторінку інформації:
+```java
+NBTTagCompound tag = new NBTTagCompound();
+tag.setString("filter", "minecraft:log 3");
+tag.setString("page", "Exotic wood found in tropical climates.");
+
+FMLInterModComms.sendMessage("NotEnoughItems", "addItemInfo", tag);
+```
+
+#### Багатосторінковий формат
+
+Використовуйте тег `"pages"` як `NBTTagList` із рядків, якщо потрібно додати понад одну сторінку:
+```java
+NBTTagCompound tag = new NBTTagCompound();
+tag.setString("filter", "minecraft:diamond_sword");
+
+NBTTagList pages = new NBTTagList();
+pages.appendTag(new NBTTagString("A powerful melee weapon."));
+pages.appendTag(new NBTTagString("Can be enchanted for extra effects."));
+
+tag.setTag("pages", pages);
+
+FMLInterModComms.sendMessage("NotEnoughItems", "addItemInfo", tag);
+```
+* Кожен елемент списку — це одна сторінка.
+* Сторінки з’являтимуться в NEI з кнопками для їх гортання.
+
+#### Відповідність предметів
+
+Усі предмети, що відповідають фільтру `filter`, відображатимуть вашу інформаційну сторінку. Повний формат фільтра див. у `config/NEI/collapsibleitems.cfg`.
+
+#### Файл конфігурації інформації про предмети
+
+Якщо ви творець збірки модів і хочете створити власні інформаційні сторінки для предметів, їх можна легко додати у файлі `config/NEI/informationpages.cfg`, де також наведено ще кілька прикладів.
