Crate limit_tui 

limit-tui

Terminal UI components with Virtual DOM rendering for Rust applications.

Build rich terminal interfaces with a component model, powered by Ratatui. Features declarative rendering, diff-based updates, and built-in syntax highlighting.

Features

• Virtual DOM: Component model with diff-based rendering
• Pre-built components: Chat views, inputs, spinners, progress bars, select menus
• Syntax highlighting: Built-in support for 150+ languages via Syntect
• Event handling: Keyboard, mouse, and resize events

Virtual DOM

Build UIs with VNode:

use limit_tui::vdom::VNode;
use std::collections::HashMap;

let ui = VNode::Element {
    tag: "div".to_string(),
    attrs: HashMap::new(),
    children: vec![
        VNode::Text("Hello, World!".to_string()),
    ],
};

Diff-Based Updates

The Virtual DOM computes minimal changes:

use limit_tui::vdom::{diff, apply, VNode};

let old_tree = VNode::Text("Hello".to_string());
let new_tree = VNode::Text("Hello, World!".to_string());

let patches = diff(&old_tree, &new_tree);
// patches contains minimal changes to transform old → new

Components

Component	Description
ChatView	Conversation display with role-based styling
InputPrompt	Interactive text input with placeholder
SelectPrompt	Single/multi-select menus
Spinner	Loading spinner with label
ProgressBar	Progress indicator

Syntax Highlighting

use limit_tui::SyntaxHighlighter;

let highlighter = SyntaxHighlighter::new()?;

let code = highlighter.highlight_to_spans(r#"
fn main() {
    println!("Hello, World!");
}
"#, "rust")?;

// Returns styled spans with syntax colors
