Since I started Vibe Coding, whenever I needed a CLI/TUI tool, I began building them in Rust for performance reasons. Even though I knew almost nothing about Rust! However, regarding interpretation and AI modification, tools like Python's Textual or JS's Ink have intuitive syntax and are convenient, but I was constantly bothered by runtime dependencies and performance overhead. So, regarding Rust, while ratatui has a good ecosystem and provides some AI assistance, I felt that it didn't have an AI-native structure (that is easy to understand). Therefore, I created two things. 1. tui.builders - An editor that visually designs a terminal UI in the browser and exports Rust code. I built it with the goal of achieving usability similar to Figma. tui.builders When you drag a widget and set its properties in the Inspector, code is generated 1:1: - Inspector: width=30, padding=2, border=rounded - Code: .w(30).p(2).border(Border::Rounded) Because of this, you can easily create TUI tools by building them on the web with an editor like Figma, exporting them immediately, and editing them alongside AI. 2. SuperLightTUI - And this is a Rust TUI library designed for this 1:1 mapping. CSS flexbox + Tailwind Since it uses a utility class approach, if you have web development experience, you can set up layouts without any separate learning. For example, you can write code with the following structure. slt::run(|ui| { ui.bordered(Border::Rounded).p(2).gap(1).col(|ui| { ui.text("hello").bold().fg(Color::Cyan); if ui.button("click").clicked { count += 1; } }); }); A single closure defines the entire app. It renders in just three lines of code, without an App struct, event loop, or trait implementation. I have incorporated many elements that I deem necessary, such as immediate-mode rendering and over 50 widgets (charts, tables, images, AI widgets, etc.). Of course, I am still not entirely satisfied with the visualization library and am working on detailed modifications, but I hope this will be helpful to those who want to maintain Rust TUI performance while keeping development speeds up. Feedback is always welcome. - tui.builders: tui.builders - GitHub: github.com/subinium/SuperLight... -
