Crate bubbletea_widgets 

bubbletea-widgets

A Rust port of the Go library charmbracelet/bubbles, providing reusable TUI components for building terminal applications with bubbletea-rs.

Overview

bubbletea-widgets offers a collection of common terminal UI components that can be easily integrated into bubbletea-rs applications. Each component follows the Elm Architecture pattern with init(), update(), and view() methods, providing a consistent and predictable API for building complex terminal user interfaces.

Features

• Type-safe key bindings with comprehensive key combination support
• Focus management system for keyboard navigation between components
• Responsive design with automatic width/height handling
• Theming support through customizable styles
• Go compatibility for easy migration from charmbracelet/bubbles
• Performance optimized with efficient rendering and state management

Components

• Input Components: TextInput, TextArea, FilePicker
• Display Components: List, Table, Progress, Spinner, Help
• Utility Components: Cursor, Viewport, Paginator, Timer, Stopwatch

Focus Management

All components implement the Component trait which provides standardized focus management:

use bubbletea_widgets::prelude::*;
use bubbletea_rs::Cmd;

fn handle_focus<T: Component>(component: &mut T) {
    let _cmd: Option<Cmd> = component.focus();
    assert!(component.focused());
    component.blur();
    assert!(!component.focused());
}

// Example with a text area (implements Component trait)
let mut textarea = textarea_new();
handle_focus(&mut textarea);

Key Bindings

Components use the type-safe key binding system from the key module:

use bubbletea_widgets::key::{Binding, KeyMap};
use crossterm::event::{KeyCode, KeyModifiers};

// Create key bindings
let confirm = Binding::new(vec![KeyCode::Enter])
    .with_help("enter", "Confirm selection");

let save = Binding::new(vec![(KeyCode::Char('s'), KeyModifiers::CONTROL)])
    .with_help("ctrl+s", "Save file");

// Implement KeyMap for your component
struct MyKeyMap {
    confirm: Binding,
    save: Binding,
}

impl KeyMap for MyKeyMap {
    fn short_help(&self) -> Vec<&Binding> {
        vec![&self.confirm, &self.save]
    }

    fn full_help(&self) -> Vec<Vec<&Binding>> {
        vec![
            vec![&self.confirm],
            vec![&self.save],
        ]
    }
}

Integration with bubbletea-rs

Components are designed to work seamlessly with bubbletea-rs models:

use bubbletea_widgets::prelude::*;
use bubbletea_rs::{Model, Cmd, Msg};

struct App {
    input: TextInput,
}

impl Model for App {
    fn init() -> (Self, Option<Cmd>) {
        let mut input = textinput_new();
        let focus_cmd = input.focus();
        (Self { input }, Some(focus_cmd))
    }

    fn update(&mut self, msg: Msg) -> Option<Cmd> {
        // Handle component updates
        if let Some(cmd) = self.input.update(msg) {
            return Some(cmd);
        }

        // Handle other messages
        match msg {
            // Your app-specific message handling
            _ => None,
        }
    }

    fn view(&self) -> String {
        format!("Enter text: {}\n{}", self.input.view(), "Press Ctrl+C to quit")
    }
}

Quick Start

Add bubbletea-widgets to your Cargo.toml:

[dependencies]
bubbletea-widgets = "0.1.0"
bubbletea-rs = "0.0.7"
crossterm = "0.27"

For convenience, you can import the prelude:

use bubbletea_widgets::prelude::*;
