Show HN: Ito – Build Terminal UIs in Lua

My friend and I, both Neovim enthusiasts, wanted a Lua-based harness to customize our terminals and editors as freely as we do in Neovim. After finding existing tools like Pi too reliant on JavaScript, we chose Lua for its fit and performance potential, eventually building ito—a minimal, Lua-native terminal UI library. Every abstraction, from providers to styling, can be done in Lua.

Inspired by Ratatui but determined to go our own way, we created ito to enable full TUI development in Lua. To showcase its power, I built a custom canvas implementation, exported it to WASM, and launched an interactive website for experimenting with Lua-based UIs. We also provide an llms.txt for vibe-coders.

The library is available at github.com/uji-labs/ito, and the accompanying harness at github.com/uji-labs/uji. The project invites users to build cool terminal interfaces with Lua, offering live preview, error-resilient editing, and tools for keyboard navigation and fullscreen mode.

Mein Freund und ich, beide Neovim-Enthusiasten, wollten ein Lua-basiertes Harness, um unsere Terminals und Editoren so frei anzupassen, wie wir es in Neovim tun. Nachdem wir bestehende Tools wie Pi zu JavaScript-abhängig gefunden hatten, wählten wir Lua wegen seiner Passung und Leistungsfähigkeit und bauten schließlich ito — ein minimalistisches, Lua-natives Terminal-UI-Bibliothek. Jede Abstraktion, von Providern bis zu Styling, kann in Lua erfolgen.

Inspiriert von Ratatui, aber entschlossen, unseren eigenen Weg zu gehen, schufen wir ito, um volle TUI-Entwicklung in Lua zu ermöglichen. Um seine Leistungsfähigkeit zu demonstrieren, baute ich eine benutzerdefinierte Canvas-Implementierung, exportierte sie nach WASM und startete eine interaktive Website zum Experimentieren mit Lua-basierten UIs. Wir stellen auch ein llms.txt für vibe-coders bereit.

Die Bibliothek ist verfügbar unter github.com/uji-labs/ito, und das begleitende Harness unter github.com/uji-labs/uji. Das Projekt lädt Nutzer ein, coole Terminal-Oberflächen mit Lua zu bauen, bietet Live-Vorschau, fehlerresistentes Editing und Tools für Tastaturnavigation und Vollbildmodus.

Mi amigo y yo, ambos entusiastas de Neovim, queríamos un arnés basado en Lua para personalizar nuestros terminales y editores tan libremente como lo hacemos en Neovim. Después de encontrar herramientas existentes como Pi demasiado dependientes de JavaScript, elegimos Lua por su idoneidad y potencial de rendimiento, construyendo eventualmente ito: una biblioteca minimalista de UI terminal nativa de Lua. Cada abstracción, desde proveedores hasta estilo, puede hacerse en Lua.

Inspirado en Ratatui pero decidido a seguir nuestro propio camino, creamos ito para permitir el desarrollo TUI completo en Lua. Para demostrar su poder, construí una implementación personalizada de canvas, lo exporté a WASM y lancé un sitio interactivo para experimentar con UIs basadas en Lua. También proporcionamos un llms.txt para vibe-coders.

La biblioteca está disponible en github.com/uji-labs/ito, y el arnés acompañante en github.com/uji-labs/uji. El proyecto invita a los usuarios a crear interfaces terminales geniales con Lua, ofreciendo preview en vivo, edición resistente a errores y herramientas para navegación de teclado y modo fullscreen.

Mon ami et moi, tous deux passionnés de Neovim, voulions un harness basé sur Lua pour personnaliser nos terminaux et éditeurs aussi librement que nous le faisons dans Neovim. Après avoir trouvé des outils existants comme Pi trop dépendants de JavaScript, nous avons choisi Lua pour son adéquation et son potentiel de performance, construisant finalement ito: une bibliothèque minimaliste de UI terminal native Lua. Chaque abstraction, des fournisseurs au style, peut être faite en Lua.

Inspiré par Ratatui mais déterminé à suivre notre propre voie, nous avons créé ito pour permettre le développement TUI complet en Lua. Pour démontrer sa puissance, j'ai implémenté un canvas personnalisé, exporté vers WASM, et lancé un site interactif pour expérimenter des UIs basées en Lua. Nous fournissons également un llms.txt pour vibe-coders.

La bibliothèque est disponible sur github.com/uji-labs/ito, et l'harness accompanying sur github.com/uji-labs/uji. Le projet invite les utilisateurs à créer des interfaces terminal cool avec Lua, offrant preview en vivo, édition résistant aux erreurs, et outils pour la navigation clavier et mode plein écran.

मेरा मित्र और मैं, दोनों Neovim उत्साही, चाहते थे एक Lua-based harness terminals and editors as freely as we do in Neovim customize। मौजूद उपकरणों की तलाश के बाद जैसे Pi JavaScript पर बहुत अधिक dependent थे, हमने Lua को its fit and performance potential के लिए चुना, eventually ito—a minimal, Lua-native terminal UI library build। हर abstraction, providers से लेकर styling तक, Lua में किया जा सकता है। Ratatui से प्रेरित लेकिन अपना रास्ता निर्धारित करने के लिए decided, ito create TUI development in Lua full enable। अपनी शक्ति को showcase के लिए, I एक custom canvas implementation built, it WASM में exported, और Lua-based UIs के साथ experimenting के लिए एक interactive website launched। We also provide an llms.txt for vibe-coders। The library github.com/uji-labs/ito पर available है, और accompanying harness github.com/uji-labs/uji पर। proyecto users to build cool terminal interfaces with Lua, offering live preview, error-resilient editing, and tools for keyboard navigation and fullscreen mode आमंत्रित करता है।

Saya dan teman saya, keduanya enthusiast Neovim, ingin harness berbasis Lua untuk men-customize terminal dan editor se bebas seperti yang kita lakukan di Neovim. Setelah menemukan alat seperti Pi yang terlalu bergantung pada JavaScript, kita memilih Lua karena kesuaian dan potensi performa, akhirnya membuat ito — library minimal Lua-native terminal UI. Setiap abstraksi, dari providers hingga styling, bisa dilakukan dalam Lua.

Diinspirasi oleh Ratatui, namun determined untuk cara kita sendiri, kita menciptakan ito untuk memungkinkan pengembangan TUI penuh dalam Lua. Untuk menunjukkan kekuatan, saya membuat implementasi canvas kustom, mengexport ke WASM, dan meluncurkan website interaktif untuk eksperimen dengan Lua-based UIs. Kita juga menyediakan llms.txt untuk vibe-coders.

Library tersedia di github.com/uji-labs/ito, dan accompanying harness di github.com/uji-labs/uji. Proyek mengundang pengguna untuk membangun cool terminal interfaces dengan Lua, menawarkan live preview, error-resilient editing, dan tools untuk keyboard navigation dan fullscreen mode.

友人と私は、どちらもNeovim熱心者であり、Neovim同様にターミナルとエディタを自由にカスタマイズするためのLuaベースのハーネスを望んでいました。既存のツールであるPiがJavaScript過度に依存していることを発見したため、性能の可能性とフィット感からLuaを選択し、最終的にlua-native terminal UI library itoを構篑しました。提供者からスタイリングまで、あらゆる抽象化はLuaで行うことができます。Ratatuiにインスパイアされましたが、自らの道を進むことを決意し、Luaでの完全なTUI開発を可能にするためにitoを作成しました。そのパワーをデモンストレーションするため、私は独自のcanvas実装を作成し、WASMにexportして、LuaベースのUIsを試すためのインタラクティブなウェブサイトを立ち上げました。vibe-coders用のllms.txtも提供しています。ライブラリはgithub.com/uji-labs/itoで利用可能であり、 accompanying harness github.com/uji-labs/uji accompany しています。プロジェクトは、Luaでcool terminal interfaces構篑するユーザーを呼びかけており、ライブプレビュー、error-resilient editing、 keyboard navigation and fullscreen modeのツールを提供しています。

Мой друг и я, оба энтузиасты Neovim, хотели Lua-based harness для кастомизации терминалов и редакторов, как мы делаем в Neovim. Найти существующие инструменты вроде Pi, которые слишком сильно зависят от JavaScript, мы выбрали Lua из-за его пригодности и потенциала производительности, в итоге построив ito — минимальную, нативную библиотеку Lua для terminal UI. Каждая абстракция, от providers до стиля, может быть feita em Lua. Вдохновлен Ratatui, но решили свой путь идти, мы создали ito для полного TUI development in Lua enable. Чтобы продемонстрировать его мощь, я сделал кастомную реализацию canvas, экспортировал её в WASM, и запустил интерактивный сайт для экспериментирования с Lua-based UIs. Мы также предоставляем llms.txt для vibe-coders. Библиотека доступна на github.com/uji-labs/ito, а accompanying harness на github.com/uji-labs/uji.
