Attribute Macros\n\n### #[derive(Component)]\n\nAutomatically implements the Component trait:\n\n```rust\n#[derive(Component)]\nstruct MyComponent {\n    // Fields\n}\n```\n\n### #[component]\n\nEnables collection of `#[effect]` methods:\n\n```rust\n#[derive(Component)]\nstruct Timer;\n\n#[component]  // Required for #[effect]\nimpl Timer {\n    // Methods\n}\n```\n\n### #[update]\n\nSimplifies update method with automatic state handling:\n\n```rust\n// Basic\n#[update]\nfn update(&self, ctx: &Context, msg: MyMsg) -> Action {\n    // No state parameter = stateless\n}\n\n// With state\n#[update]\nfn update(&self, ctx: &Context, msg: MyMsg, mut state: MyState) -> Action {\n    // State automatically fetched and passed\n}\n\n// With topics\n#[update(msg

    "content": "# RxTUI Documentation\n\nRxTUI is a reactive terminal user interface framework for Rust that brings modern component-based architecture to the terminal. It combines React-like patterns with efficient terminal rendering through virtual DOM diffing.\n\n## Table of Contents\n\n- [Getting Started](#getting-started)\n- [Terminal Modes](#terminal-modes)\n- [Components](#components)\n- [The node! Macro](#the-node-macro)\n- [State Management](#state-management)\n- [Message Handling](#message-handling)\n- [Topic-Based Communication](#topic-based-communication)\n- [Layout System](#layout-system)\n- [Styling](#styling)\n- [Event Handling](#event-handling)\n- [Built-in Components](#built-in-components)\n- [Effects (Async)](#effects-async)\n- [Examples](#examples)\n\n## Getting Started\n\nAdd RxTUI to your `Cargo.toml`:\n\n```toml\n[dependencies]\nrxtui = \"0.1\"\ntokio = { version = \"1.0\", features = [\"full\"] }  # Required for async effects\n```\n\nNote: The `effects` feature is enabled by default. To disable it:\n\n```toml\n[dependencies]\nrxtui = { version = \"0.1\", default-features = false }\n```\n\nCreate your first app:\n\n```rust\nuse rxtui::prelude::*;\n\n#[derive(Component)]\nstruct HelloWorld;\n\nimpl HelloWorld {\n    #[view]\n    fn view(&self, ctx: &Context) -> Node {\n        node! {\n            div(bg: blue, pad: 2, @key_global(esc): ctx.handler(())) [\n                text(\"Hello, Terminal!\", color: white, bold),\n                text(\"Press Esc to exit\", color: white)\n            ]\n        }\n    }\n}\n\nfn main() -> std::io::Result<()> {\n    App::new()?.run(HelloWorld)\n}\n```\n\n<div align='center'>• • •</div>\n\n## Terminal Modes\n\nRxTUI supports two terminal rendering modes: **Alternate Screen** (default) and **Inline**.\n\n#### Alternate Screen Mode (Default)\n\nThe default mode uses the terminal's alternate screen buffer. This is ideal for full-screen applications:\n\n```rust\nfn main() -> std::io::Result<()> {\n    App::new()?.run(MyComponent)  // Uses alternate screen\n}\n```\n\nCharacteristics:\n- Takes over the full terminal screen\n- Content disappears when the app exits\n- Best for interactive applications, editors, dashboards\n\n#### Inline Mode\n\nInline mode renders directly in the terminal buffer without switching screens. Content persists after the app exits, making it ideal for CLI tools:\n\n```rust\nfn main() -> std::io::Result<()> {\n    // Simple inline mode with defaults\n    App::inline()?.run(MyComponent)?;\n\n    // This prints after the UI since content is preserved\n    println!(\"Done! The UI above is preserved.\");\n    Ok(())\n}\n```\n\nCharacteristics:\n- Renders in the main terminal buffer\n- Content persists in terminal history after exit\n- Height is content-based by default (grows to fit)\n- Mouse capture disabled by default (allows terminal scrolling)\n\n#### Custom Inline Configuration\n\nFor fine-grained control over inline rendering:\n\n```rust\nuse rxtui::{App, InlineConfig, InlineHeight};\n\nfn main() -> std::io::Result<()> {\n    let config = InlineConfig {\n        // Fixed height of 10 lines\n        height: InlineHeight::Fixed(10),\n        // Show cursor during rendering\n        cursor_visible: true,\n        // Preserve output after exit\n        preserve_on_exit: true,\n        // Don't capture mouse (allow terminal scrolling)\n        mouse_capture: false,\n    };\n\n    App::inline_with_config(config)?.run(MyComponent)\n}\n```\n\n#### Height Modes\n\nControl how inline mode determines rendering height:\n\n```rust\n// Fixed number of lines\nInlineHeight::Fixed(10)\n\n// Grow to fit content, with optional maximum\nInlineHeight::Content { max: Some(24) }  // Max 24 lines\nInlineHeight::Content { max: None }       // No limit (default)\n\n// Fill remaining terminal space below cursor\nInlineHeight::Fill { min: 5 }  // At least 5 lines\n```\n\n<div align='center'>• • •</div>\n\n## Components\n\nEverything in RxTUI is a component. Think of them as self-contained UI pieces that know how to manage their own state and behavior. Components have three main capabilities: handling events (through `update`), rendering UI (through `view`), and running async operations (through `effect`):\n\n#### Basic Component\n\n```rust\n#[derive(Component)]\nstruct TodoList;\n\nimpl TodoList {\n    #[update]\n    fn update(&self, ctx: &Context, msg: TodoMsg, mut state: TodoState) -> Action {\n        // Messages come here from events in your view\n        // You update state, then return Action::update(state) to re-render\n    }\n\n    #[view]\n    fn view(&self, ctx: &Context, state: TodoState) -> Node {\n        // This renders your UI using the current state\n        // Uses the node! macro to build the UI tree\n    }\n\n    #[effect]\n    async fn fetch_todos(&self, ctx: &Context, state: TodoState) {\n        // Async effects for background tasks\n        // Useful for timers, API calls, or any async operation\n    }\n}\n```\n\n#### Component Trait\n\nThe `#[derive(Component)]` macro automatically implements the Component trait. You can also implement it manually:\n\n```rust\nimpl Component for MyComponent {\n    fn update(&self, ctx: &Context, msg: Box<dyn Message>, topic: Option<&str>) -> Action {\n        // Handle messages\n    }\n\n    fn view(&self, ctx: &Context) -> Node {\n        // Return UI tree\n    }\n\n    fn effects(&self, ctx: &Context) -> Vec<Effect> {\n        // Return async effects\n    }\n}\n```\n\n#### Complete Working Example\n\nHere's a complete working example of a stopwatch component with async effects:\n\n```rust\nuse rxtui::prelude::*;\n\n#[derive(Component)]\nstruct Stopwatch;\n\nimpl Stopwatch {\n    #[update]\n    fn update(&self, _ctx: &Context, tick: bool, state: u64) -> Action {\n        if !tick {\n            return Action::exit();\n        }\n        Action::update(state + 10)\n    }\n\n    #[view]\n    fn view(&self, ctx: &Context, state: u64) -> Node {\n        let seconds = state / 1000;\n        let centiseconds = (state % 1000) / 10;\n\n        node! {\n            div(\n                pad: 2,\n                align: center,\n                w_frac: 1.0,\n                gap: 1,\n                @key(esc): ctx.handler(false),\n                @char_global('q'): ctx.handler(false)\n            ) [\n                richtext[\n                    text(\"Elapsed: \", color: white),\n                    text(\n                        format!(\" {}.{:02}s \", seconds, centiseconds),\n                        color: \"#ffffff\",\n                        bg: \"#9d29c3\",\n                        bold\n                    ),\n                ],\n                text(\"press esc or q to exit\", color: bright_black)\n            ]\n        }\n    }\n\n    #[effect]\n    async fn tick(&self, ctx: &Context) {\n        loop {\n            tokio::time::sleep(std::time::Duration::from_millis(10)).await;\n            ctx.send(true);\n        }\n    }\n}\n\nfn main() -> std::io::Result<()> {\n    App::new()?.fast_polling().run(Stopwatch)\n}\n```\n\nThis example demonstrates:\n- State management with the `#[update]` method handling timer ticks\n- Async effects with the `#[effect]` method for continuous updates\n- Rich text formatting with inline styles and hex colors\n- Global keyboard event handling with `@key` and `@char_global`\n- Layout control with centering and responsive width (`w_frac: 1.0`)\n\n<div align='center'>• • •</div>\n\n## The node! Macro\n\nThe `node!` macro is how you actually build your UI. It gives you a clean, declarative syntax that lives inside your component's `view` method. Instead of imperatively creating and configuring widgets, you describe what the UI should look like:\n\n#### Basic Syntax\n\n```rust\nnode! {\n    // Root node\n    div(...<properties>, ...<handlers>) [\n\n        // Children nodes here\n        text(\"content\", ...<properties>),\n        div(...) [\n\n            // Nested nodes\n            ...<children>\n        ]\n    ]\n}\n```\n\nExample:\n```rust\nnode! {\n    div(\n        bg: blue,\n        pad: 2,\n        border: white,\n        @key(enter): ctx.handler(\"submit\"),\n        @click: ctx.handler(\"clicked\")\n    ) [\n        richtext(align: center, wrap: word) [\n            text(\"Welcome to \", color: bright_white),\n            text(\"RxTUI\", color: yellow, bold),\n            text(\"!\", color: bright_white)\n        ],\n        div [\n            text(\"Nested content\")\n        ]\n    ]\n}\n```\n\n#### Elements\n\n##### Expressions\n\nYou can use any Rust expression that returns a `Node` by wrapping it in parentheses:\n\n```rust\nnode! {\n    div [\n        // Variable\n        (my_node_variable),\n\n        // Match expression\n        (match state.status {\n            Loading => node! { text(\"Loading...\") },\n            Ready => node! { text(\"Ready!\") },\n        }),\n\n        // If expression\n        (if condition {\n            node! { text(\"True branch\") }\n        } else {\n            node! { text(\"False branch\") }\n        }),\n\n        // Method call\n        (self.create_node()),\n    ]\n}\n```\n\n##### Spread Operator\n\nUse the `...` spread operator to expand a `Vec<Node>` as children:\n\n```rust\nnode! {\n    div [\n        // Spread a vector of nodes\n        ...(vec![\n            node! { text(\"Item 1\") },\n            node! { text(\"Item 2\") },\n            node! { text(\"Item 3\") },\n        ]),\n\n        // Spread from iterator\n        ...(state.items.iter().map(|item| {\n            node! {\n                div(pad: 1) [\n                    text(&item.name)\n                ]\n            }\n        }).collect::<Vec<Node>>()),\n\n        // Combine with regular children\n        text(\"Header\", bold),\n        ...(item_nodes),\n        text(\"Footer\"),\n    ]\n}\n```\n\nThis is particularly useful for rendering lists or collections dynamically.\n\n##### Div Container\n\n```rust\nnode! {\n    div(\n        // Layout\n        dir: vertical,      // or horizontal, v, h\n        gap: 2,            // space between children\n        wrap: wrap,        // wrap mode\n\n        // Sizing\n        w: 50,             // fixed width\n        h: 20,             // fixed height\n        w_frac: 0.5,        // 50% of parent width\n        h_frac: 0.8,        // 80% of parent height\n        w_auto,            // automatic width\n        h_content,         // size to content\n\n        // Styling\n        bg: blue,          // background color\n        pad: 2,            // padding all sides\n        pad_h: 1,          // horizontal padding\n        pad_v: 1,          // vertical padding\n\n        // Borders\n        border: white,     // border color\n        border_style: rounded,\n        border_color: yellow,\n        border_edges: BorderEdges::TOP | BorderEdges::BOTTOM,\n\n        // Interaction\n        focusable,         // can receive focus\n        overflow: scroll,  // scroll, hidden, auto\n        show_scrollbar: true,\n\n        // Positioning\n        absolute,          // absolute positioning\n        top: 5,\n        left: 10,\n        z: 100            // z-index\n    ) [\n        // Children here\n    ]\n}\n```\n\n##### Text\n\n```rust\nnode! {\n    div [\n        // Simple text\n        text(\"Hello\"),\n\n        // Styled text\n        text(\"Styled\", color: red, bold, italic, underline),\n\n        // Dynamic text\n        text(format!(\"Count: {}\", count)),\n\n        // Text with wrapping\n        text(\"Long text...\", wrap: word),\n\n        // Text with alignment\n        text(\"Centered\", align: center),\n        text(\"Right aligned\", align: right)\n    ]\n}\n```\n\n##### Rich Text\n\n```rust\nnode! {\n    div [\n        richtext [\n            text(\"Normal \"),\n            text(\"Bold\", bold),\n            text(\" and \"),\n            text(\"Colored\", color: red)\n        ],\n\n        // With top-level styling\n        richtext(wrap: word) [\n            text(\"Line 1 \"),\n            text(\"Important\", color: yellow, bold),\n            text(\" continues...\")\n        ],\n\n        // With alignment\n        richtext(align: center) [\n            text(\"Centered \"),\n            text(\"rich text\", bold)\n        ]\n    ]\n}\n```\n\n##### Stacks\n\n```rust\nnode! {\n    div [\n        // Vertical stack (default)\n        vstack [\n            text(\"Top\"),\n            text(\"Bottom\")\n        ],\n\n        // Horizontal stack\n        hstack(gap: 2) [\n            text(\"Left\"),\n            text(\"Right\")\n        ]\n    ]\n}\n```\n\n##### Components\n\n```rust\nnode! {\n    div [\n        // Embed other components\n        node(MyComponent::new(\"config\")),\n        node(Counter)\n    ]\n}\n```\n\n##### Spacers\n\n```rust\nnode! {\n    div [\n        text(\"Top\"),\n        spacer(2),  // 2 lines of space\n        text(\"Bottom\")\n    ]\n}\n```\n\n#### Event Handlers\n\n```rust\nnode! {\n    div(\n        focusable,\n        // Mouse events\n        @click: ctx.handler(Msg::Clicked),\n        // Keyboard events (requires focus)\n        @char('a'): ctx.handler(Msg::KeyA),\n        @key(enter): ctx.handler(Msg::Enter),\n        @key(Char('-')): ctx.handler(Msg::Minus),\n        // Focus events\n        @focus: ctx.handler(Msg::Focused),\n        @blur: ctx.handler(Msg::Blurred),\n        // Global events (work without focus)\n        @char_global('q'): ctx.handler(Msg::Quit),\n        @key_global(esc): ctx.handler(Msg::Exit),\n        // Any character handler\n        @any_char: |ch| ctx.handler(Msg::Typed(ch))\n    ) [\n        text(\"Interactive\")\n    ]\n}\n```\n\n#### Optional Properties\n\nUse `!` suffix for optional properties:\n\n```rust\nnode! {\n    div(\n        // Only applied if Some\n        bg: (optional_color)!,\n        w: (optional_width)!,\n        border: (if selected { Some(Color::Yellow) } else { None })!\n    ) [\n        text(\"Conditional styling\")\n    ]\n}\n```\n\n<div align='center'>• • •</div>\n\n## State Management\n\nThese are the heart of your component's logic. State is just your data - what your component needs to remember.\n\n#### Component State\n\n```rust\n#[derive(Debug, Clone, Default)]\nstruct MyState {\n    counter: i32,\n    text: String,\n}\n\nimpl MyComponent {\n    #[update]\n    fn update(&self, ctx: &Context, msg: MyMsg, mut state: MyState) -> Action {\n        // The #[update] macro automatically fetches state\n        // and passes it as the last parameter\n\n        state.counter += 1;\n        Action::update(state)  // Save the new state\n    }\n\n    #[view]\n    fn view(&self, ctx: &Context, state: MyState) -> Node {\n        // The #[view] macro automatically fetches state\n        node! {\n            div [\n                text(format!(\"Counter: {}\", state.counter))\n            ]\n        }\n    }\n}\n```\n\n#### Manual State Access\n\n```rust\nfn update(&self, ctx: &Context, msg: Box<dyn Message>, _topic: Option<&str>) -> Action {\n    // Manually get state (or initialize with Default)\n    let mut state = ctx.get_state::<MyState>();\n\n    // Modify state\n    state.counter += 1;\n\n    // Return updated state\n    Action::update(state)\n}\n```\n\n<div align='center'>• • •</div>\n\n## Message Handling\n\nMessages are how components respond to events - user clicks, key presses, timers firing. When a message arrives, you update your state, and the UI automatically re-renders.\n\n#### Basic Messages\n\n```rust\n#[derive(Debug, Clone)]\nenum MyMsg {\n    Click,\n    KeyPress(char),\n    Update(String),\n}\n\nimpl MyComponent {\n    #[update]\n    fn update(&self, ctx: &Context, msg: MyMsg, mut state: MyState) -> Action {\n        match msg {\n            MyMsg::Click => {\n                state.clicked = true;\n                Action::update(state)\n            }\n            MyMsg::KeyPress(ch) => {\n                state.text.push(ch);\n                Action::update(state)\n            }\n            MyMsg::Update(text) => {\n                state.text = text;\n                Action::update(state)\n            }\n        }\n    }\n}\n```\n\n#### Actions\n\nUpdate methods return an Action:\n\n```rust\npub enum Action {\n    Update(Box<dyn State>),              // Update component state\n    UpdateTopic(String, Box<dyn State>), // Update topic state\n    None,                                // No action\n    Exit,                                // Exit application\n}\n```\n\n#### Message with Value\n\n```rust\n// In view\nnode! {\n    div [\n        @any_char: ctx.handler_with_value(|ch| Box::new(MyMsg::Typed(ch)))\n    ]\n}\n```\n\n<div align='center'>• • •</div>\n\n## Topic-Based Communication\n\nTopics enable cross-component communication without direct references.\n\n#### Sending to Topics\n\n```rust\nimpl Dashboard {\n    #[update]\n    fn update(&self, ctx: &Context, msg: DashboardMsg, state: DashboardState) -> Action {\n        match msg {\n            DashboardMsg::NotifyAll => {\n                // Send message to topic\n                ctx.send_to_topic(\"notifications\", NotificationMsg::Alert);\n                Action::none()\n            }\n        }\n    }\n}\n```\n\n#### Receiving Topic Messages\n\n```rust\nimpl NotificationBar {\n    // Static topic\n    #[update(msg = LocalMsg, topics = [\"notifications\" => NotificationMsg])]\n    fn update(&self, ctx: &Context, messages: Messages, mut state: State) -> Action {\n        match messages {\n            Messages::LocalMsg(msg) => {\n                // Handle local messages\n            }\n            Messages::NotificationMsg(msg) => {\n                // Handle topic messages\n                // Returning Action::update claims topic ownership\n                state.notifications.push(msg);\n                Action::update(state)\n            }\n        }\n    }\n}\n```\n\n#### Dynamic Topics\n\n```rust\nstruct Counter {\n    topic_name: String,  // Topic determined at runtime\n}\n\nimpl Counter {\n    // Dynamic topic from field\n    #[update(msg = CounterMsg, topics = [self.topic_name => ResetSignal])]\n    fn update(&self, ctx: &Context, messages: Messages, mut state: CounterState) -> Action {\n        match messages {\n            Messages::CounterMsg(msg) => { /* ... */ }\n            Messages::ResetSignal(_) => {\n                // Reset when signal received\n                Action::update(CounterState::default())\n            }\n        }\n    }\n}\n```\n\n#### Topic State\n\n```rust\n// Write topic state (first writer becomes owner)\nAction::UpdateTopic(\"app.settings\".to_string(), Box::new(settings))\n\n// Read topic state from any component\nlet settings: Option<Settings> = ctx.read_topic(\"app.settings\");\n```\n\n<div align='center'>• • •</div>\n\n## Layout System\n\nRxTUI provides a flexible layout system with multiple sizing modes.\n\n#### Dimension Types\n\n```rust\npub enum Dimension {\n    Fixed(u16),       // Exact size in cells\n    Percentage(f32),  // Percentage of parent (stored 0.0 to 1.0)\n    Auto,            // Share remaining space equally\n    Content,         // Size based on children\n}\n```\n\n#### Layout Examples\n\n```rust\nnode! {\n    // Fixed layout\n    div(w: 80, h: 24) [\n        text(\"Fixed size\")\n    ],\n\n    // Percentage-based\n    div(w_frac: 0.5, h_frac: 0.8) [\n        text(\"50% width, 80% height\")\n    ],\n\n    // Auto sizing - share remaining space\n    hstack [\n        div(w: 20) [ text(\"Fixed\") ],\n        div(w_auto) [ text(\"Auto 1\") ],  // Gets 50% of remaining\n        div(w_auto) [ text(\"Auto 2\") ]   // Gets 50% of remaining\n    ],\n\n    // Content-based sizing\n    div(w_content, h_content) [\n        text(\"Size fits content\")\n    ]\n}\n```\n\n#### Direction and Wrapping\n\n```rust\nnode! {\n    // Vertical layout (default)\n    div(dir: vertical, gap: 2) [\n        text(\"Line 1\"),\n        text(\"Line 2\")\n    ],\n\n    // Horizontal layout\n    div(dir: horizontal, gap: 1) [\n        text(\"Col 1\"),\n        text(\"Col 2\")\n    ],\n\n    // With wrapping\n    div(dir: horizontal, wrap: wrap, w: 40) [\n        // Children wrap to next line when width exceeded\n        div(w: 15) [ text(\"Item 1\") ],\n        div(w: 15) [ text(\"Item 2\") ],\n        div(w: 15) [ text(\"Item 3\") ]  // Wraps to next line\n    ]\n}\n```\n\n#### Scrolling\n\n```rust\nnode! {\n    div(\n        h: 10,              // Fixed container height\n        overflow: scroll,   // Enable scrolling\n        show_scrollbar: true,\n        focusable          // Must be focusable for keyboard scrolling\n    ) [\n        // Content taller than container\n        text(\"Line 1\"),\n        text(\"Line 2\"),\n        // ... many more lines\n        text(\"Line 50\")\n    ]\n}\n```\n\nScrolling controls:\n\n- **Arrow keys**: Scroll up/down by 1 line\n- **Page Up/Down**: Scroll by container height\n- **Home/End**: Jump to top/bottom\n- **Mouse wheel**: Scroll up/down\n\nNote: Only vertical scrolling is currently implemented.\n\n<div align='center'>• • •</div>\n\n## Styling\n\n#### Colors\n\nRxTUI supports multiple color formats:\n\n```rust\nnode! {\n    div [\n        // Named colors\n        text(\"Red\", color: red),\n        text(\"Bright Blue\", color: bright_blue),\n\n        // Hex colors\n        text(\"Hex\", color: \"#FF5733\"),\n\n        // RGB\n        text(\"RGB\", color: (Color::Rgb(255, 128, 0))),\n\n        // Conditional\n        text(\"Status\", color: (if ok { Color::Green } else { Color::Red }))\n    ]\n}\n```\n\nAvailable named colors:\n\n- Basic: `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, `white`\n- Bright: `bright_black`, `bright_red`, `bright_green`, `bright_yellow`, `bright_blue`, `bright_magenta`, `bright_cyan`, `bright_white`\n\n#### Text Alignment\n\nText and RichText nodes support horizontal alignment within their containers:\n\n```rust\nnode! {\n    div(w: 50) [\n        // Basic text alignment\n        text(\"Left aligned\", align: left),\n        text(\"Centered text\", align: center),\n        text(\"Right aligned\", align: right),\n\n        // RichText alignment\n        richtext(align: center) [\n            text(\"This \"),\n            text(\"rich text\", bold),\n            text(\" is centered\")\n        ],\n\n        // Alignment with wrapping\n        text(\n            \"Long text that wraps to multiple lines. Each line will be aligned.\",\n            wrap: word,\n            align: right\n        )\n    ]\n}\n```\n\nNote: Text nodes with alignment automatically expand to fill their parent's width to enable proper alignment calculation.\n\n#### Div Alignment (Flexbox-style)\n\nDivs support CSS Flexbox-style alignment for their children along both the main and cross axes:\n\n```rust\nnode!

{\n    div(\n        focusable,\n\n        // Mouse\n        @click: ctx.handler(Msg::Clicked),\n\n        // Keyboard\n        @char('a'): ctx.handler(Msg::PressedA),\n        @key(enter): ctx.handler(Msg::Confirmed),\n        @key(backspace): ctx.handler(Msg::Delete),\n\n        // Focus\n        @focus: ctx.handler(Msg::GainedFocus),\n        @blur: ctx.handler(Msg::LostFocus)\n    ) [\n        text(\"Click or press keys\")\n    ]\n}\n```\n\n#### Global Events\n\nGlobal events work regardless of focus:\n\n```rust\nnode! {\n    div(\n        // Application-wide shortcuts\n        @char_global('q'): ctx.handler(Msg::Quit),\n        @key_global(esc): ctx.handler(Msg::Cancel),\n        @char_global('/'): ctx.handler(Msg::Search)\n    ) [\n        // Children here\n    ]\n}\n```\n\n#### Focus Navigation\n\n- **Tab**: Move to next focusable element\n- **Shift+Tab**: Move to previous focusable element\n\n#### Programmatic Focus\n\nUse the `Context` focus helpers to move focus immediately after a render:\n\n```rust\n#[view]\nfn view(&self, ctx: &Context, state: MyState) -> Node {\n    if ctx.is_first_render() {\n        ctx.focus_self(); // focus the first focusable node in this component\n    }\n\n    node! {\n        div [\n            input(focusable),\n            button(focusable)\n        ]\n    }\n}\n```\n\n- `ctx.focus_self()` focuses the first focusable element inside the component's subtree.\n- `ctx.focus_first()` focuses the first focusable element in the entire app.\n- `ctx.is_first_render()` is handy for gating autofocus so you do not wrestle with user-driven focus changes later.\n\n<div align='center'>• • •</div>\n\n## Built-in Components\n\n#### TextInput\n\nA full-featured text input component:\n\n```rust\nuse rxtui::components::TextInput;\n\nnode!

Component System (`lib/component.rs`)\n\nThe component system is the heart of the framework, providing a React-like component model with state management and message passing.\n\n#### Component Trait\n\n```rust\npub trait Component: 'static {\n    fn update(&self, ctx: &Context, msg: Box<dyn Message>, topic: Option<&str>) -> Action {\n        Action::default()\n    }\n\n    fn view(&self, ctx: &Context) -> Node;\n\n    #[cfg(feature = \"effects\")]\n    fn effects(&self, ctx: &Context) -> Vec<Effect> {\n        vec![]\n    }\n\n    fn as_any(&self) -> &dyn Any;\n    fn as_any_mut(&mut self) -> &mut dyn Any;\n}\n```\n\n**Key Design Decisions:**\n- Components are stateless - all state is managed by Context\n- Update method receives optional topic for cross-component messaging\n- Components can be derived using `#[derive(Component)]` macro\n- Effects support async background tasks (with feature flag)\n- Default implementations provided for update and effects\n\n#### Message and State Traits\n\nBoth Message and State traits are auto-implemented for any type that is `Clone + Send + Sync + 'static`:\n\n```rust\npub trait Message: Any + Send + Sync + 'static {\n    fn as_any(&self) -> &dyn Any;\n    fn clone_box(&self) -> Box<dyn Message>;\n}\n\npub trait State: Any + Send + Sync + 'static {\n    fn as_any(&self) -> &dyn Any;\n    fn as_any_mut(&mut self) -> &mut dyn Any;\n    fn clone_box(&self) -> Box<dyn State>;\n}\n```\n\n**Extension Traits for Downcasting:**\n- `MessageExt` provides `downcast<T>()` for message type checking\n- `StateExt` provides `downcast<T>()` for state type checking\n\n#### Actions\n\nComponents return actions from their update method:\n\n```rust\n#[derive(Default)]\npub enum Action {\n    Update(Box<dyn State>),              // Update component's local state\n    UpdateTopic(String, Box<dyn State>), // Update topic state (first writer owns)\n    None,                                // No action needed\n    #[default]\n    Exit,                                // Exit the application\n}\n```\n\nHelper methods for ergonomic construction:\n```rust\nAction::update(state)        // Create Update action\nAction::update_topic(topic, state)  // Create UpdateTopic action\nAction::none()              // Create None action\nAction::exit()              // Create Exit action\n```\n\n### 2. Context System (`lib/app/context.rs`)\n\nThe Context provides components with everything they need to function:\n\n#### Core Components\n\n**Context Structure:**\n- `current_component_id`: Component being processed\n- `dispatch`: Message dispatcher\n- `states`: Component state storage (StateMap)\n- `topics`: Topic-based messaging (Arc<TopicStore>)\n- `message_queues`: Regular message queues (Arc<RwLock<HashMap>>)\n- `topic_message_queues`: Topic message queues (Arc<RwLock<HashMap>>)\n\n**StateMap:**\n- Stores component states with interior mutability using `Arc<RwLock<HashMap>>`\n- `get_or_init<T>()`: Get state or initialize with Default, handles type mismatches\n- Type-safe state retrieval with automatic downcasting\n- Thread-safe with RwLock protection\n\n**Dispatcher:**\n- Routes messages to components or topics\n- `send_to_id(component_id, message)`: Direct component messaging\n- `send_to_topic(topic, message)`: Topic-based messaging\n- Shared message queue storage with Context\n\n**TopicStore:**\n- Manages topic ownership (first writer becomes owner)\n- Stores topic states separately from component states\n- Tracks which component owns which topic via `owners: RwLock<HashMap<String, ComponentId>>`\n- Thread-safe with RwLock protection\n- `update_topic()`: Returns bool indicating if update was successful\n\n#### Context Public API\n\n```rust\nimpl Context {\n    // Message handling\n    pub fn handler<M: Message>(&self, msg: M) -> Box<dyn Fn() + 'static>;\n    pub fn handler_with_value<F, M, T>(&self, f: F) -> Box<dyn Fn(T) + 'static>;\n\n    // State management\n    pub fn get_state<S: State + Default + Clone>(&self) -> S;\n    pub fn get_state_or<S: State + Clone>(&self, default: S) -> S;\n\n    // Direct messaging\n    pub fn send<M: Message>(&self, msg: M);\n\n    // Topic messaging\n    pub fn send_to_topic<M: Message>(&self, topic: &str, msg: M);\n    pub fn read_topic<S: State + Clone>(&self, topic: &str) -> Option<S>;\n}\n```\n\n#### Message Flow\n\n1. **Direct Messages**: Sent to specific component via `ctx.handler(msg)` which creates closures\n2. **Topic Messages**: Sent via `ctx.send_to_topic(topic, msg)`\n   - If topic has owner → delivered only to owner\n   - If no owner → broadcast to all components until one claims it\n\n### 3. Topic-Based Messaging System\n\nA unique feature for cross-component communication without direct references:\n\n#### Concepts\n\n- **Topics**: Named channels for messages (e.g., \"counter_a\", \"global_state\")\n- **Ownership**: First component to write to a topic becomes its owner\n- **Unassigned Messages**: Messages to unclaimed topics are broadcast to all components\n\n#### How It Works\n\n1. **Sending Messages:**\n   ```rust\n   ctx.send_to_topic(\"my-topic\", MyMessage);\n   ```\n\n2. **Claiming Ownership:**\n   ```rust\n   // First component to return this action owns the topic\n   Action::UpdateTopic(\"my-topic\".to_string(), Box::new(MyState))\n   ```\n\n3. **Handling Topic Messages (Using Macros):**\n   ```rust\n   // With the #[update] macro:\n   #[update(msg = MyMsg, topics = [\"my-topic\" => TopicMsg])]\n   fn update(&self, ctx: &Context, messages: Messages, mut state: MyState) -> Action {\n       match messages {\n           Messages::MyMsg(msg) => { /* handle regular message */ }\n           Messages::TopicMsg(msg) => { /* handle topic message */ }\n       }\n   }\n\n   // Dynamic topics from component fields:\n   #[update(msg = MyMsg, topics = [self.topic_name => TopicMsg])]\n   fn update(&self, ctx: &Context, messages: Messages, state: MyState) -> Action {\n       // Topic name from self.topic_name field\n   }\n   ```\n\n4. **Reading Topic State:**\n   ```rust\n   let state: Option<MyState> = ctx.read_topic(\"my-topic\");\n   ```\n\n**Design Rationale:**\n- Enables decoupled component communication\n- Supports both single-writer/multiple-reader and broadcast patterns\n- Automatic ownership management prevents conflicts\n- Idempotent updates - multiple attempts to claim ownership are safe\n\n### 4. Application Core (`lib/app/core.rs`)\n\nThe App struct manages the entire application lifecycle:\n\n#### Initialization\n```rust\nApp::new()  // Standard initialization\nApp::with_config(RenderConfig { ... })  // With custom config\n```\n- Enables terminal raw mode and alternate screen\n- Hides cursor and enables mouse capture\n- Initializes double buffer for flicker-free rendering\n- Sets up event handling with crossterm\n- Creates effect runtime (if feature enabled) using Tokio\n\n#### Event Loop\n\nThe main loop (`run_loop`) follows this sequence:\n\n1. **Component Tree Expansion**:\n   - Start with root component\n   - Recursively expand components to VNodes\n   - Assign component IDs based on tree position using `ComponentId::child(index)` method (e.g., \"0\", \"0.0\", \"0.1\")\n\n2. **Message Processing**:\n   - Components drain all pending messages (regular + topic)\n   - Messages trigger state updates via component's `update` method\n   - Handle actions (Update, UpdateTopic, Exit, None)\n\n3. **Virtual DOM Update**:\n   - VDom diffs new tree against current\n   - Generates patches for changes\n   - Updates render tree\n\n4. **Layout & Rendering**:\n   - Calculate positions and sizes based on Dimension types\n   - Render to back buffer\n   - Diff buffers and apply changes to terminal\n\n5. **Event Handling**:\n   - Process keyboard/mouse events (poll with 16ms timeout by default)\n   - Events trigger new messages via event handlers\n   - Handle terminal resize events\n\n6. **Effect Management** (if feature enabled):\n   - Spawn effects for newly mounted components\n   - Cleanup effects for unmounted components\n   - Effects run in Tokio runtime with JoinHandle tracking\n\n#### Component Tree Expansion\n\nThe `expand_component_tree` method is crucial:\n\n1. Drains all messages for the component (both regular and topic messages)\n2. Processes each message:\n   - Regular messages → component's update\n   - Topic messages → check if component handles topic\n3. Handles actions:\n   - `Update` → update component state via StateMap\n   - `UpdateTopic` → update topic state, claim ownership if first\n   - `Exit` → propagate exit signal\n   - `None` → no operation\n4. Calls component's `view` to get UI tree\n5. Recursively expands child components\n\n### 5. Node Types\n\nThree levels of node representation:\n\n#### Node (`lib/node/mod.rs`)\nHigh-level component tree:\n```rust\npub enum Node {\n    Component(Arc<dyn Component>),  // Component instance (Arc for sharing)\n    Div(Div<Node>),                 // Container with children\n    Text(Text),                     // Text content\n    RichText(RichText),            // Styled text with multiple spans\n}\n```\n\n#### VNode (`lib/vnode.rs`)\nVirtual DOM nodes after component expansion:\n```rust\npub enum VNode {\n    Div(Div<VNode>),        // Expanded div (generic over child type)\n    Text(Text),             // Text node\n    RichText(RichText),     // Rich text node\n}\n```\n\n#### RenderNode (`lib/render_tree/node.rs`)\nPositioned nodes ready for drawing:\n```rust\npub struct RenderNode {\n    pub node_type: RenderNodeType,\n    pub x: u16, pub y: u16,           // Position\n    pub width: u16, pub height: u16,   // Size\n    pub content_width: u16,            // Actual content size\n    pub content_height: u16,\n    pub scroll_y: u16,                 // Vertical scroll offset\n    pub scrollable: bool,              // Has overflow:scroll/auto\n    pub style: Option<Style>,          // Visual style\n    pub children: Vec<Rc<RefCell<RenderNode>>>,\n    pub parent: Option<Weak<RefCell<RenderNode>>>,\n    pub focusable: bool,\n    pub focused: bool,\n    pub dirty: bool,\n    pub z_index: i32,\n    // Event handlers stored as Rc<dyn Fn()>\n}\n```\n\n### 6. Div System (`lib/node/div.rs`)\n\nDivs are generic containers that can hold different child types:\n\n```rust\npub struct Div<T> {\n    pub children: Vec<T>,\n    pub styles: DivStyles,           // Base, focus, hover styles\n    pub gap: Option<u16>,\n    pub wrap: Option<WrapMode>,\n    pub focusable: bool,\n    pub overflow: Option<Overflow>,\n    pub show_scrollbar: Option<bool>,\n    pub callbacks: EventCallbacks,   // Click, focus, blur handlers\n    pub key_handlers: Vec<KeyHandler>,\n    pub global_key_handlers: Vec<KeyHandler>,\n    pub key_with_modifiers_handlers: Vec<KeyWithModifiersHandler>,\n    pub any_char_handler: Option<Rc<dyn Fn(char) -> Box<dyn Message>>>,\n}\n```\n\n#### DivStyles\n```rust\npub struct DivStyles {\n    pub base: Option<Style>,    // Normal style\n    pub focus: Option<Style>,   // When focused\n    pub hover: Option<Style>,   // When hovered (future)\n}\n```\n\n#### Builder Pattern\n\nBoth the builder pattern and the `node!` macro are fully supported ways to create UIs. Choose based on your preference and use case.\n\n```rust\n// Using the builder pattern\nDiv::new()\n    .background(Color::Blue)\n    .padding(Spacing::all(2))\n    .direction(Direction::Horizontal)\n    .width(20)\n    .height_fraction(0.5)\n    .focusable(true)\n    .overflow(Overflow::Scroll)\n    .show_scrollbar(true)\n    .on_click(handler)\n    .on_key(Key::Enter, handler)\n    .on_key_with_modifiers(KeyWithModifiers::with_ctrl(Key::Char('a')), handler)\n    .children(vec![...])\n\n// Using the node! macro\nnode! {\n    div(\n        bg: blue,\n        pad: 2,\n        dir: horizontal,\n        w: 20,\n        h_frac: 0.5,\n        focusable,\n        overflow: scroll,\n        show_scrollbar: true\n    ) [\n        // Children using expressions or spread\n        (child_node),\n        ...(child_nodes)\n    ]\n}\n```\n\n### 7. Virtual DOM (`lib/vdom.rs`)\n\nManages UI state and efficient updates:\n\n#### Core Operations\n\n1. **Render**: Accept new VNode tree\n2. **Diff**: Compare with current tree\n3. **Patch**: Apply changes to render tree\n4. **Layout**: Calculate positions based on constraints\n5. **Draw**: Output to terminal\n\n#### Diffing Algorithm (`lib/diff.rs`)\n\nGenerates minimal patches:\n```rust\npub enum Patch {\n    Replace {\n        old: Rc<RefCell<RenderNode>>,\n        new: VNode,\n    },\n    UpdateText {\n        node: Rc<RefCell<RenderNode>>,\n        new_text: String,\n        new_style: Option<TextStyle>,\n    },\n    UpdateRichText {\n        node: Rc<RefCell<RenderNode>>,\n        new_spans: Vec<TextSpan>,\n    },\n    UpdateProps {\n        node: Rc<RefCell<RenderNode>>,\n        div: Div<VNode>,\n    },\n    AddChild {\n        parent: Rc<RefCell<RenderNode>>,\n        child: VNode,\n        index: usize,\n    },\n    RemoveChild {\n        parent: Rc<RefCell<RenderNode>>,\n        index: usize,\n    },\n    ReorderChildren {\n        parent: Rc<RefCell<RenderNode>>,\n        moves: Vec<Move>,\n    },\n}\n```\n\n### 8. Layout System (`lib/render_tree/tree.rs`)\n\nSophisticated layout engine supporting multiple sizing modes:\n\n#### Dimension Types\n```rust\npub enum Dimension {\n    Fixed(u16),       // Exact size in cells\n    Percentage(f32),  // Percentage of parent (stored 0.0-1.0)\n    Auto,            // Share remaining space equally\n    Content,         // Size based on children\n}\n```\n\n#### Layout Algorithm\n\n1. **Fixed**: Use exact size\n2. **Percentage**: Calculate from parent size (content box after padding)\n3. **Content**:\n   - Horizontal: width = sum of children + gaps, height = max child\n   - Vertical: width = max child, height = sum of children + gaps\n4. **Auto**: Divide remaining space equally among auto-sized elements\n\n#### Text Wrapping\nMultiple wrapping modes supported:\n- `None`: No wrapping\n- `Character`: Break at any character\n- `Word`: Break at word boundaries\n- `WordBreak`: Try words, break if necessary\n\n#### Scrolling Support\n- **Vertical scrolling**: Implemented with scroll_y offset\n- **Scrollbar rendering**: Optional visual indicator showing position\n- **Keyboard navigation**: Up/Down arrows, PageUp/PageDown, Home/End\n- **Mouse wheel**: ScrollUp/ScrollDown events\n- **Content tracking**: content_height vs container height\n- **Focus requirement**: Container must be focusable for keyboard scrolling\n- **Note**: Horizontal scrolling not yet implemented\n\n### 9. Rendering Pipeline (`lib/app/renderer.rs`)\n\nConverts render tree to terminal output:\n\n#### Rendering Steps\n\n1. **Clear Background**: Fill with parent background color or inherit\n2. **Draw Borders**: Render border characters if present (single, double, rounded, thick)\n3. **Apply Padding**: Adjust content area based on Spacing\n4. **Handle Scrolling**: Apply scroll_y offset for scrollable containers\n5. **Render Content**:\n   - For containers: Recurse into children respecting z-index\n   - For text: Draw text with wrapping and style\n   - For rich text: Draw styled segments preserving individual styles\n6. **Apply Clipping**: Ensure content stays within bounds using clip_rect\n7. **Draw Scrollbar**: Show position indicator if enabled and scrollable\n\n#### Style Inheritance\n- Text nodes inherit parent's background if not specified\n- Focus styles override normal styles when focused\n- Children can override parent styles\n- Rich text spans maintain individual styles\n\n### 10. Terminal Output System\n\n#### Double Buffering (`lib/buffer.rs`)\n\nEliminates flicker completely:\n\n```rust\npub struct DoubleBuffer {\n    front_buffer: ScreenBuffer,  // Currently displayed\n    back_buffer: ScreenBuffer,   // Next frame\n    width: u16,\n    height: u16,\n}\n```\n\n**Cell Structure:**\n```rust\npub struct Cell {\n    pub char: char,\n    pub fg: Option<Color>,\n    pub bg: Option<Color>,\n    pub style: TextStyle,  // Bitflags for bold, italic, etc.\n}\n```\n\n**Diff Process:**\n1. Render to back buffer\n2. Compare with front buffer cell-by-cell\n3. Generate list of changed cells with positions\n4. Apply updates to terminal in optimal order\n5. Swap buffers\n\n#### Terminal Renderer (`lib/terminal.rs`)\n\nOptimized output with multiple strategies:\n\n1. **Batch Updates**: Group cells with same colors\n2. **Skip Unchanged**: Only update modified cells\n3. **Optimize Movements**: Minimize cursor jumps using manhattan distance\n4. **Style Batching**: Combine style changes\n5. **ANSI Escape Sequences**: Direct terminal control\n\n### 11. Event System (`lib/app/events.rs`)\n\nComprehensive input handling using crossterm:\n\n#### Keyboard Events\n\n**Focus Navigation:**\n- Tab: Next focusable element\n- Shift+Tab: Previous focusable element\n\n**Scrolling (for focused scrollable elements):**\n- Up/Down arrows: Scroll by 1 line\n- PageUp/PageDown: Scroll by container height\n- Home/End: Jump to top/bottom\n\n**Event Routing:**\n1. Global handlers always receive events (marked with `_global`)\n2. Focused element receives local events\n3. Character and key handlers triggered with modifiers support\n\n#### Mouse Events\n\n**Click Handling:**\n1. Find node at click position using tree traversal\n2. Set focus if focusable\n3. Trigger click handler\n\n**Scroll Handling:**\n1. Find scrollable node under cursor\n2. Apply scroll delta (3 lines per wheel event)\n3. Clamp to content bounds\n\n### 12. RichText System (`lib/node/rich_text.rs`)\n\nProvides inline text styling with multiple spans:\n\n#### Core Structure\n```rust\npub struct RichText {\n    pub spans: Vec<TextSpan>,\n    pub style: Option<TextStyle>,  // Top-level style for wrapping, etc.\n}\n\npub struct TextSpan {\n    pub content: String,\n    pub style: Option<TextStyle>,\n}\n```\n\n#### Builder API\n```rust\nRichText::new()\n    .text(\"Normal text \")\n    .colored(\"red text\", Color::Red)\n    .bold(\"bold text\")\n    .italic(\"italic text\")\n    .styled(\"custom\", TextStyle { ... })\n    .wrap(TextWrap::Word)\n```\n\n#### Special Features\n- **Multiple Spans**: Each span can have different styling\n- **Top-Level Styling**: Apply wrapping or common styles to all spans\n- **Helper Methods**: `bold_all()`, `color()` for all spans\n- **Text Wrapping**: Preserves span styles across wrapped lines\n- **Cursor Support**: `with_cursor()` for text input components\n\n### 13. Style System (`lib/style.rs`)\n\nRich styling capabilities:\n\n#### Colors\n- 16 standard terminal colors (Black, Red, Green, Yellow, Blue, Magenta, Cyan, White)\n- Bright variants (BrightBlack through BrightWhite)\n- RGB support (24-bit color) via `Rgb(u8, u8, u8)`\n- Hex color parsing support\n\n#### Text Styles\n```rust\npub struct TextStyle {\n    pub color: Option<Color>,\n    pub background: Option<Color>,\n    pub bold: Option<bool>,\n    pub italic: Option<bool>,\n    pub underline: Option<bool>,\n    pub strikethrough: Option<bool>,\n    pub wrap: Option<TextWrap>,\n}\n```\n\nStyle merging support with `TextStyle::merge()` for inheritance.\n\n#### Borders\n```rust\npub struct Border {\n    pub enabled: bool,\n    pub style: BorderStyle,  // Single, Double, Rounded, Thick\n    pub color: Color,\n    pub edges: BorderEdges,  // Bitflags for TOP, RIGHT, BOTTOM, LEFT\n}\n```\n\n#### Position\n```rust\npub enum Position {\n    Relative,  // Normal flow\n    Absolute,  // Positioned relative to parent\n}\n```\n\nWith top, right, bottom, left offsets for absolute positioning.\n\n#### Overflow\n```rust\npub enum Overflow {\n    None,   // Content not clipped\n    Hidden, // Content clipped at boundaries\n    Scroll, // Content clipped but scrollable\n    Auto,   // Auto show scrollbars\n}\n```\n\n### 14. Macro System\n\nProvides ergonomic APIs for building UIs:\n\n#### node! Macro (`lib/macros/node.rs`)\nDeclarative syntax for building UI trees:\n```rust\nnode! {\n    div(bg: blue, pad: 2, @click: ctx.handler(Msg::Click), @key(enter): ctx.handler(Msg::Enter)) [\n        text(\"Hello\", color: white),\n        div(border: white) [\n            text(\"Nested\")\n        ]\n    ]\n}\n```\n\nFeatures:\n- Property shortcuts (bg, pad, w, h, etc.)\n- Color literals (red, blue, \"#FF5733\")\n- Event handler syntax with @ prefix\n- Optional properties with ! suffix\n- Stack helpers (hstack, vstack)\n\n#### Attribute Macros (from rxtui-macros crate)\n\n**#[derive(Component)]**: Auto-implements Component trait with providers pattern\n\n**#[component]**: Collects #[effect] methods for async support, implements `__component_effects_impl`\n\n**#[update]**: Handles message downcasting and state management, supports topic routing\n\n**#[view]**: Automatically fetches component state via `ctx.get_state()`\n\n**#[effect]**: Marks async methods as effects, collected by #[component]\n\n### 15. Effects System (`lib/effect/`, requires feature flag)\n\nSupports async background tasks:\n\n#### Effect Runtime (`lib/effect/runtime.rs`)\n- Spawns Tokio runtime for async execution\n- Manages effect lifecycle per component with JoinHandle tracking\n- Automatic cleanup on component unmount via abort()\n- Effects stored in HashMap<ComponentId, Vec<JoinHandle>>\n\n#### Effect Type\n```rust\npub type Effect = Pin<Box<dyn Future<Output = ()> + Send>>;\n```\n\n#### Effect Definition with Macros\n```rust\n#[component]\nimpl MyComponent {\n    #[effect]\n    async fn background_task(&self, ctx: &Context) {\n        loop {\n            tokio::time::sleep(Duration::from_secs(1)).await;\n            ctx.send(MyMsg::Tick);\n        }\n    }\n\n    #[effect]\n    async fn with_state(&self, ctx: &Context, state: MyState) {\n        // State automatically fetched via ctx.get_state()\n        if state.should_process {\n            // Do work\n        }\n    }\n}\n```\n\n#### Common Use Cases\n- Timers and periodic updates\n- Network requests with reqwest/hyper\n- File system monitoring with notify\n- WebSocket connections\n- Background computations\n\n### 16.

{ div(focusable) [] }\n}\n```\n\n### Optional Properties\n\n```rust\ndiv(\n    // Use ! suffix for Option<T> values\n    bg: (optional_color)!,\n    w: (optional_width)!,\n    border: (if selected { Some(yellow) } else { None })!,\n)\n\ninput(\n    placeholder: (maybe_placeholder)!,\n    w: (state.width)!,\n    focus_border: (state.focus_color)!,\n)\n```\n\n## Colors\n\n### Named Colors\n\nBasic: `black`, `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, `white`\n\nBright: `bright_black`, `bright_red`, `bright_green`, `bright_yellow`, `bright_blue`, `bright_magenta`, `bright_cyan`, `bright_white`\n\n### Color Formats\n\n```rust\n// Named (no prefix)\ncolor: red\ncolor: bright_blue\n\n// Hex string\ncolor: \"#FF5733\"\ncolor: \"#F50\"\n\n// RGB expression\ncolor: (Color::Rgb(255, 128, 0))\n\n// Variable\ncolor: (my_color)\n\n// Conditional\ncolor: (if ok { green } else { red })\n```\n\n## Common Patterns\n\n### Loading State\n\nUse expressions in parentheses for dynamic content:\n\n```rust\nnode! {\n    div [\n        (match state.status {\n            Loading => node! { text(\"Loading...\", color: yellow) },\n            Error(e) => node! { text(format!(\"Error: {}\", e), color: red) },\n            Success(data) => node! { text(format!(\"Data: {}\", data)) },\n        })\n    ]\n}\n```\n\n### List Rendering\n\nUse the spread operator `...` to expand collections:\n\n```rust\n// Spread a Vec<Node> as children\nnode! {\n    div [\n        ...(state.items.iter().map(|item| {\n            node! {\n                div [\n                    text(&item.name)\n                ]\n            }\n        }).collect::<Vec<Node>>())\n    ]\n}\n\n// Or prepare the list first\nlet item_nodes: Vec<Node> = state.items.iter()\n    .map(|item| node! {\n        div [\n            text(&item.name)\n        ]\n    })\n    .collect();\n\nnode! {\n    div [\n        text(\"Items:\", bold),\n        ...(item_nodes)\n    ]\n}\n```\n\n### Conditional Rendering\n\nUse expressions for conditional content:\n\n```rust\nnode! {\n    div [\n        (if state.show_header {\n            node! { text(\"Header\", bold) }\n        } else {\n            node! { spacer(0) }  // Empty placeholder\n        }),\n\n        text(\"Always visible\"),\n\n        (if let Some(message) = &state.message {\n            node! { text(message, color: yellow) }\n        } else {\n            node! { spacer(0) }\n        })\n    ]\n}\n```\n\n### Keyboard Shortcuts\n\n```rust\n#[view]\nfn view(&self, ctx: &Context) -> Node {\n    node! {\n        div(focusable, @key(ctrl + 'c'): ctx.handler(Msg::Exit)) [\n            text(\"Press Ctrl+C to exit\", color: bright_red)\n        ]\n    }\n}\n```\n\n### Scrollable Container\n\n```rust\ndiv(\n    h: 10,               // fixed height\n    overflow: scroll,\n    show_scrollbar: true,\n    focusable           // for keyboard scrolling\n) [\n    // content taller than container\n]\n```\n\n### Modal Overlay\n\n```rust\ndiv [\n    // Main content\n    div [ /* ... */ ],\n\n    // Modal\n    if state.show_modal {\n        div(absolute, top: 0, left: 0, w_frac: 1.0, h_frac: 1.0, bg: black, z: 1000) [\n            div(w: 40, h: 10, bg: white, border: black, pad: 2) [\n                text(\"Modal Content\", color: black)\n            ]\n        ]\n    }\n]\n```\n\n## Update Patterns\n\n### Basic Update\n\n```rust\n#[update]\nfn update(&self, ctx: &Context, msg: MyMsg, mut state: MyState) -> Action {\n    match msg {\n        MyMsg::Increment => {\n            state.count += 1;\n            Action::update(state)\n        }\n    }\n}\n```\n\n### Topic Messaging\n\n```rust\n// Send to topic\nctx.send_to_topic(\"my.topic\", MyMessage);\n\n// Receive from topic\n#[update(msg = LocalMsg, topics = [\"my.topic\" => TopicMsg])]\nfn update(&self, ctx: &Context, messages: Messages, mut state: State) -> Action {\n    match messages {\n        Messages::LocalMsg(msg) => { /* local */ }\n        Messages::TopicMsg(msg) => { /* from topic */ }\n    }\n}\n```\n\n### Dynamic Topics\n\n```rust\nstruct Component {\n    topic: String,\n}\n\n#[update(msg = Msg, topics = [self.topic => TopicMsg])]\nfn update(&self, ctx: &Context, messages: Messages, state: State) -> Action {\n    // Topic name from field\n}\n```\n\n## Effects (Async)\n\nEffects are enabled by default. Just add tokio:\n```toml\n[dependencies]\nrxtui = \"0.1\"\ntokio = { version = \"1\", features = [\"full\"] }\n```\n\n### Timer Effect\n\n```rust\n#[component]\nimpl Timer {\n    #[effect]\n    async fn tick(&self, ctx: &Context) {\n        loop {\n            tokio::time::sleep(Duration::from_secs(1)).await;\n            ctx.send(TimerMsg::Tick);\n        }\n    }\n}\n```\n\n### Effect with State\n\n```rust\n#[effect]\nasync fn monitor(&self, ctx: &Context, state: MyState) {\n    if state.should_monitor {\n        // Do async work\n    }\n}\n```\n\n## TextInput\n\n### Basic Usage\n\n```rust\nnode! {\n    div [\n        input(placeholder: \"Enter text...\", focusable)\n    ]\n}\n```\n\n### Customized\n\n```rust\nnode! {\n    div [\n        input(\n            placeholder: \"Password\",\n            password,           // mask input\n            border: yellow,\n            w: 40,\n            content_color: green,\n            cursor_color: white,\n            focusable\n        )\n    ]\n}\n```\n\n### Builder API\n\n```rust\nnode(\n    TextInput::new()\n        .placeholder(\"Email...\")\n        .width(50)\n        .border(Color::Cyan)\n        .focus_border(Color::Yellow)\n)\n```\n\n## Layout Tips\n\n### Responsive Layout\n\n```rust\ndiv(w_frac: 1.0, h_frac: 1.0) [  // Full screen\n    div(w_frac: 0.3) [ /* 30% sidebar */ ],\n    div(w_frac: 0.7) [ /* 70% main */ ]\n]\n```\n\n### Auto Sizing\n\n```rust\nhstack [\n    div(w: 20) [ /* fixed */ ],\n    div(w_auto) [ /* expands */ ],\n    div(w: 20) [ /* fixed */ ]\n]\n```\n\n### Content Sizing\n\n```rust\ndiv(w_content, h_content) [\n    // Size fits children\n]\n```\n\n## Keyboard Shortcuts\n\n### Focus Navigation\n- `Tab` - Next focusable\n- `Shift+Tab` - Previous focusable\n\n### Scrolling (when focused)\n- `↑/↓` - Scroll up/down\n- `Page Up/Down` - Page scroll\n- `Home/End` - Jump to top/bottom\n\n### TextInput\n- `←/→` - Move cursor\n- `Home/End` - Line start/end\n- `Alt+B/F` - Word left/right\n- `Ctrl+W` - Delete word backward\n- `Alt+D` - Delete word forward\n- `Ctrl+U` - Delete to line start\n- `Ctrl+K` - Delete to line end\n\n## Actions\n\n```rust\nAction::update(state)        // Update component state\nAction::update_topic(topic, state)  // Update topic state\nAction::none()              // No action\nAction::exit()              // Exit app\n```\n\n## App Configuration\n\n### Terminal Modes\n\n```rust\n// Alternate screen mode (default) - full-screen, content disappears on exit\nApp::new()?.run(MyComponent)?;\n\n// Inline mode - renders in terminal, content persists after exit\nApp::inline()?.run(MyComponent)?;\n\n// Custom inline configuration\nuse rxtui::{InlineConfig, InlineHeight};\n\nlet config = InlineConfig {\n    height: InlineHeight::Fixed(10),      // Fixed 10 lines\n    // height: InlineHeight::Content { max: Some(24) },  // Grow to fit, max 24\n    // height: InlineHeight::Fill { min: 5 },            // Fill remaining space\n    cursor_visible: false,\n    preserve_on_exit: true,               // Keep output after exit\n    mouse_capture: false,                 // Allow terminal scrolling\n};\nApp::inline_with_config(config)?.run(MyComponent)?;\n```\n\n### Render Config\n\n```rust\nlet mut app = App::new()?\n    .render_config(RenderConfig {\n        poll_duration_ms: 16,      // Event poll timeout\n        use_double_buffer: true,   // Flicker-free rendering\n        use_diffing: true,         // Optimize updates\n        use_alternate_screen: true, // Separate screen\n    });\napp.run(MyComponent)?;\n```\n\n## Debugging\n\n```rust\n// Disable optimizations for debugging\nlet mut app = App::new()?\n    .render_config(RenderConfig {\n        use_double_buffer: false,\n        use_diffing: false,\n        poll_duration_ms: 100,\n    });\napp.run(MyComponent)?;\n```\n\n## Performance Tips\n\n1. Minimize state updates\n2. Use topics only when needed\n3. Avoid recreating large trees\n4. Use `w_content`/`h_content` sparingly\n5. Profile with `RenderConfig`\n\n## Common Gotchas\n\n1. **Focus required**: Most events need `focusable`\n2. **State cloning**: State is cloned on update\n3. **Topic ownership**: First updater owns topic\n4. **Scrolling**: Container must be `focusable`\n\n## Import Everything\n\n```rust\nuse rxtui::prelude::*;\n```\n\nIncludes:\n- Core: `App`, `Context`, `Component`, `Node`, `Action`\n- State: `State`, `Message`\n- Style: `Color`, `Style`, `Direction`, `Spacing`, `Border`, `BorderStyle`\n- Macros: `node!`, `#[component]`, `#[update]`, `#[view]`, `#[effect]`\n- Components: `TextInput`\n- Keys: `Key`, `KeyWithModifiers`\n- Terminal Modes: `TerminalMode`, `InlineConfig`, `InlineHeight`\n"

You either work with low-level escape sequences (error-prone and tedious) or use immediate-mode libraries that require you to manage all state manually. **RxTUI** takes a different approach.\n\nWe bring the retained-mode, component-based architecture that revolutionized web development to the terminal:\n\n- [x] **Declarative UI** - Describe what your UI should look like, not how to change it\n- [x] **True Composability** - Build complex apps from simple, reusable components\n- [x] **Best of Both Worlds** - Elm's message architecture meets React's components\n- [x] **TUI Optimizations** - Automatic diffing, dirty tracking, and minimal redraws\n- [x] **Inline Mode** - Render directly in terminal with persistent output for CLI tools\n\n<br />\n\n<div align='center'>\n  <img width=\"100%\" alt=\"align demo\" src=\"https://github.com/user-attachments/assets/bff6886f-7d38-4e90-a512-04d79a3e6246\" />\n</div>\n\n<br />\n\n# <sub>QUICK START</sub>\n\n### <span>1</span>&nbsp;&nbsp;Install RxTUI\n\nAdd to your `Cargo.toml`:\n\n```toml\n[dependencies]\nrxtui = \"0.1\"\n```\n\n### <span>2</span>&nbsp;&nbsp;Create Your First App\n\nA simple working example showing separation of state management and UI building:\n\n```rust\nuse rxtui::prelude::*;\n\n#[derive(Component)]\nstruct Counter;\n\nimpl Counter {\n    #[update]\n    fn update(&self, _ctx: &Context, msg: &str, mut count: i32) -> Action {\n        match msg {\n            \"inc\" => Action::update(count + 1),\n            \"dec\" => Action::update(count - 1),\n            _ => Action::exit(),\n        }\n    }\n\n    #[view]\n    fn view(&self, ctx: &Context, count: i32) -> Node {\n        node! {\n            div(\n                pad: 2,\n                align: center,\n                w_frac: 1.0,\n                gap: 1,\n                @key(up): ctx.handler(\"inc\"),\n                @key(down): ctx.handler(\"dec\"),\n                @key(esc): ctx.handler(\"exit\")\n            ) [\n                text(format!(\"Count: {count}\"), color: white, bold),\n                text(\"use ↑/↓ to change, esc to exit\", color: bright_black)\n            ]\n        }\n    }\n}\n\nfn main() -> std::io::Result<()> {\n    App::new()?.run(Counter)\n}\n```\n\n### <span>3</span>&nbsp;&nbsp;Run Your App\n\n```bash\ncargo run\n```\n\n<img width=\"100%\" alt=\"counter demo\" src=\"https://github.com/user-attachments/assets/c841f1e6-8bf9-4b5a-bed5-97bc31cc3537\" />\n\n<div align='center'>• • •</div>\n\n# <sub>DOCUMENTATION</sub>\n\n| Document                                  | Description                                |\n| ----------------------------------------- | ------------------------------------------ |\n| **[Examples](./examples)**                | Collection of example apps                 |\n| **[Documentation](DOCS.md)**              | Complete framework documentation           |\n| **[Tutorial](TUTORIAL.md)**               | Step-by-step guide from basics to advanced |\n| **[API Reference](API_REFERENCE.md)**     | Detailed API documentation                 |\n| **[Quick Reference](QUICK_REFERENCE.md)** | Handy cheat sheet for common patterns      |\n| **[Implementation](IMPLEMENTATION.md)**   | Internal architecture details              |\n\n<div align='center'>• • •</div>\n\n# <sub>DEVELOPMENT</sub>\n\nWant to contribute?

    "content": "# RxTUI Tutorial\n\nLearn RxTUI step by step, from basics to advanced features.\n\n## Prerequisites\n\n- Basic Rust knowledge\n- A terminal that supports colors and mouse input\n- Rust toolchain installed\n\n## Chapter 1: Your First Component\n\nLet's start with the simplest possible RxTUI app.\n\n### Hello World\n\n```rust\nuse rxtui::prelude::*;\n\n// Define a component\n#[derive(Component)]\nstruct HelloWorld;\n\nimpl HelloWorld {\n    // Define how it looks\n    #[view]\n    fn view(&self, ctx: &Context) -> Node {\n        node! {\n            div(bg: blue, pad: 2, @key_global(esc): ctx.handler(())) [\n                text(\"Hello, RxTUI!\", color: white, bold),\n                text(\"Press Esc to exit\", color: white)\n            ]\n        }\n    }\n}\n\nfn main() -> std::io::Result<()> {\n    App::new()?.run(HelloWorld)\n}\n```\n\nRun it:\n```bash\ncargo run\n```\n\nPress `Esc` to exit.\n\n### What's happening?\n\n1. **Component**: We define a struct and derive `Component`\n2. **View**: The `#[view]` method returns what to display\n3. **node! macro**: Creates the UI tree declaratively\n4. **App**: Manages the terminal and event loop\n\n## Chapter 2: Adding State\n\nMost UIs need to manage data. Let's add state to our component.\n\n### Counter with State\n\n```rust\nuse rxtui::prelude::*;\n\n// State holds our data\n#[derive(Debug, Clone, Default)]\nstruct CounterState {\n    count: i32,\n}\n\n#[derive(Component)]\nstruct Counter;\n\nimpl Counter {\n    #[view]\n    fn view(&self, _ctx: &Context, state: CounterState) -> Node {\n        node! {\n            div(bg: black, pad: 2) [\n                text(format!(\"Count: {}\", state.count), color: white)\n            ]\n        }\n    }\n}\n\nfn main() -> std::io::Result<()> {\n    App::new()?.run(Counter)\n}\n```\n\nThe `#[view]` macro automatically fetches the state and passes it as a parameter.\n\n## Chapter 3: Handling Events\n\nNow let's make it interactive by adding messages and updates.\n\n### Interactive Counter\n\n```rust\nuse rxtui::prelude::*;\n\n// Messages represent events\n#[derive(Debug, Clone)]\nenum CounterMsg {\n    Increment,\n    Decrement,\n    Exit,\n}\n\n#[derive(Debug, Clone, Default)]\nstruct CounterState {\n    count: i32,\n}\n\n#[derive(Component)]\nstruct Counter;\n\nimpl Counter {\n    // Handle messages and update state\n    #[update]\n    fn update(&self, _ctx: &Context, msg: CounterMsg, mut state: CounterState) -> Action {\n        match msg {\n            CounterMsg::Increment => {\n                state.count += 1;\n                Action::update(state)  // Save new state\n            }\n            CounterMsg::Decrement => {\n                state.count -= 1;\n                Action::update(state)\n            }\n            CounterMsg::Exit => Action::exit(),  // Exit app\n        }\n    }\n\n    #[view]\n    fn view(&self, ctx: &Context, state: CounterState) -> Node {\n        node! {\n            div(bg: black, pad: 2, @char_global('+'): ctx.handler(CounterMsg::Increment), @char_global('-'): ctx.handler(CounterMsg::Decrement), @char_global('q'): ctx.handler(CounterMsg::Exit)) [\n                text(format!(\"Count: {}\", state.count), color: white),\n                text(\"Press +/- to change, q to quit\", color: gray)\n            ]\n        }\n    }\n}\n```\n\n### The Update Cycle\n\n1. User presses a key\n2. Event handler creates a message\n3. `update` processes the message\n4. State changes\n5. View re-renders with new state\n\n## Chapter 4: Building UIs with node!\n\nThe `node!` macro is how you build UIs. Let's explore its features.\n\n### Layout and Styling\n\n```rust\n#[view]\nfn view(&self, ctx: &Context, state: MyState) -> Node {\n    node! {\n        // Vertical layout with padding\n        div(bg: \"#1a1a1a\", pad: 2, gap: 1) [\n            // Title with styling\n            text(\"My App\", color: cyan, bold, underline),\n\n            // Horizontal layout\n            hstack(gap: 2) [\n                // Fixed width box\n                div(w: 20, h: 5, border: white) [\n                    text(\"Left panel\")\n                ],\n\n                // Percentage width\n                div(w_frac: 0.5, border: blue) [\n                    text(\"Center (50%)\")\n                ],\n\n                // Auto-sizing\n                div(w_auto, border: green) [\n                    text(\"Right (auto)\")\n                ]\n            ],\n\n            // Spacer\n            spacer(2),\n\n            // Footer\n            text(\"Status: Ready\", color: bright_green)\n        ]\n    }\n}\n```\n\n### Rich Text\n\n```rust\nnode! {\n    div [\n        // Inline styled text\n        richtext [\n            text(\"Status: \"),\n            text(\"SUCCESS\", color: green, bold),\n            text(\" - \"),\n            text(\"5 items\", color: yellow),\n            text(\" processed\")\n        ]\n    ]\n}\n```\n\n## Chapter 5: Interactive Elements\n\nLet's make clickable buttons and focusable elements.\n\n### Buttons and Focus\n\n```rust\n#[derive(Debug, Clone)]\nenum AppMsg {\n    ButtonClicked(String),\n    InputFocused,\n}\n\n#[view]\nfn view(&self, ctx: &Context, state: AppState) -> Node {\n    node! {\n        div(pad: 2) [\n            text(\"Click buttons or use Tab to navigate:\", color: yellow),\n\n            hstack(gap: 2) [\n                // Clickable button\n                div(\n                    border: white,\n                    pad: 1,\n                    focusable,  // Can receive focus\n                    focus_style: ({\n                        Style::default()\n                            .background(Color::Blue)\n                            .border(Color::Yellow)\n                    }),\n                    @click: ctx.handler(AppMsg::ButtonClicked(\"One\".into())),\n                    @key(enter): ctx.handler(AppMsg::ButtonClicked(\"One\".into()))\n                ) [\n                    text(\"Button 1\")\n                ],\n\n                // Another button\n                div(border: white, pad: 1, focusable, @click: ctx.handler(AppMsg::ButtonClicked(\"Two\".into())), @key(enter): ctx.handler(AppMsg::ButtonClicked(\"Two\".into()))) [\n                    text(\"Button 2\")\n                ]\n            ],\n\n            // Display which was clicked\n            text(format!(\"Last clicked: {}\", state.last_clicked))\n        ]\n    }\n}\n```\n\n### Focus Navigation\n\n- **Tab**: Move to next focusable element\n- **Shift+Tab**: Move to previous\n- **Enter**: Activate focused element\n\n## Chapter 6: Text Input\n\nRxTUI includes a built-in TextInput component.\n\n### Using TextInput\n\n```rust\nuse rxtui::prelude::*;\nuse rxtui::components::TextInput;\n\n#[derive(Debug, Clone)]\nenum FormMsg {\n    Submit,\n    Exit,\n}\n\n#[derive(Debug, Clone, Default)]\nstruct FormState {\n    submitted: bool,\n}\n\n#[derive(Component)]\nstruct Form;\n\nimpl Form {\n    #[update]\n    fn update(&self, _ctx: &Context, msg: FormMsg, mut state: FormState) -> Action {\n        match msg {\n            FormMsg::Submit => {\n                state.submitted = true;\n                Action::update(state)\n            }\n            FormMsg::Exit => Action::exit(),\n        }\n    }\n\n    #[view]\n    fn view(&self, ctx: &Context, state: FormState) -> Node {\n        node!

Here's what to explore next:\n\n1. **Read the full documentation**: Check `DOCS.md` for complete API details\n2. **Study the examples**: Run and modify the example apps\n3. **Build something**: Create your own TUI application\n4. **Explore advanced features**:\n   - Custom components\n   - Complex layouts\n   - Performance optimization\n   - Custom rendering\n\n## Tips for Success\n\n1. **Start simple**: Build basic components first, then combine them\n2. **Use the type system**: Let Rust's types guide your design\n3. **Think in components**: Break complex UIs into reusable pieces\n4. **Handle errors gracefully**: Always provide feedback to users\n5. **Test interactively**: TUIs are best tested by using them\n\n## Common Patterns\n\n### Loading States\n\n```rust\n#[view]\nfn view(&self, ctx: &Context, state: DataState) -> Node {\n    node! {\n        div [\n            match &state.data {\n                Loading => text(\"Loading...\", color: yellow),\n                Error(e) => text(format!(\"Error: {}\", e), color: red),\n                Success(data) => text(format!(\"Data: {}\", data)),\n            }\n        ]\n    }\n}\n```\n\n### Modal Dialogs\n\n```rust\n#[view]\nfn view(&self, ctx: &Context, state: AppState) -> Node {\n    node! {\n        div [\n            // Main content\n            div [ /* ... */ ],\n\n            // Modal overlay\n            if state.show_modal {\n                div(\n                    absolute,\n                    top: 0, left: 0,\n                    w_frac: 1.0, h_frac: 1.0,\n                    bg: (Color::Black.with_alpha(128)),  // Semi-transparent\n                    z: 1000\n                ) [\n                    // Modal content\n                    div(\n                        w: 40, h: 10,\n                        bg: white,\n                        border: black,\n                        pad: 2\n                    ) [\n                        text(\"Modal Dialog\", color: black, bold),\n                        // Modal content...\n                    ]\n                ]\n            }\n        ]\n    }\n}\n```\n\nHappy coding with RxTUI!\n"

    "content": "# Inline Rendering Mode for rxtui\n\n## Problem Statement\n\nrxtui currently renders exclusively to the terminal's alternate screen buffer. This mode:\n- Clears the terminal and takes over the full screen\n- Content disappears when the app exits\n- Not suitable for CLI tools that want persistent inline output\n\n**Goal**: Add inline rendering mode that renders directly in the terminal without alternate screen, with proper terminal scrolling support.\n\n---\n\n## Terminal Scrolling Nuances\n\n### The Core Challenge\n\nWhen rendering inline (not in alternate screen), terminal scrolling creates coordinate system problems:\n\n```\nBefore rendering (cursor at row 45 of 50-row terminal):\n┌─────────────────────────┐\n│ ... terminal history    │ row 1-44\n│ cursor here ►           │ row 45\n│                         │ row 46-50 (empty)\n└─────────────────────────┘\n\nAfter printing 10 lines:\n┌─────────────────────────┐\n│ ... terminal history    │ rows shifted up by 5\n│ our line 1              │\n│ our line 2              │\n│ ...                     │\n│ our line 10             │ row 50\n└─────────────────────────┘\n\nProblem: Our \"starting position\" (row 45) no longer exists at row 45!\n         It scrolled up. Re-rendering to row 45 writes to wrong location.\n```\n\n### Strategy: Space Reservation\n\nReserve rendering space BEFORE drawing content. This guarantees we have room and establishes a stable coordinate system.\n\n```\nStep 1: Query cursor position → (col=0, row=45)\nStep 2: Calculate content height → 10 lines\nStep 3: Print 10 newlines (reserves space, causes scroll if needed)\nStep 4: Move cursor back up 10 lines → now at stable \"origin\"\nStep 5: Render content → writes into reserved space\nStep 6: On re-render → move to origin, overwrite in place\n```\n\n**Why this works**: After reservation, all scrolling has already happened. The origin position is stable for the lifetime of the app.\n\n---\n\n## Comprehensive Design\n\n### 1. New Types\n\n**File**: `lib/app/config.rs`\n\n```rust\n/// Terminal rendering mode\npub enum TerminalMode {\n    /// Full-screen alternate buffer (current behavior)\n    AlternateScreen,\n    /// Inline rendering in main terminal buffer\n    Inline(InlineConfig),\n}\n\n/// Configuration for inline rendering mode\npub struct InlineConfig {\n    /// How to determine rendering height\n    pub height: InlineHeight,\n    /// Whether to show cursor during rendering\n    pub cursor_visible: bool,\n    /// Whether to preserve output after app exits\n    pub preserve_on_exit: bool,\n}\n\n/// Height determination strategy for inline mode\npub enum InlineHeight {\n    /// Fixed number of lines\n    Fixed(u16),\n    /// Grow to fit content, with optional maximum\n    Content { max: Option<u16> },\n    /// Fill remaining terminal space below cursor\n    Fill { min: u16 },\n}\n\nimpl Default for InlineConfig {\n    fn default() -> Self {\n        Self {\n            height: InlineHeight::Content { max: Some(24) },\n            cursor_visible: false,\n            preserve_on_exit: true,\n        }\n    }\n}\n```\n\n**File**: `lib/app/inline.rs` (new file)\n\n```rust\n/// Runtime state for inline rendering\npub(crate) struct InlineState {\n    /// Row where our rendering area starts (after space reservation)\n    pub origin_row: u16,\n    /// Column where rendering starts (usually 0)\n    pub origin_col: u16,\n    /// Current reserved height\n    pub reserved_height: u16,\n    /// Terminal dimensions at initialization\n    pub terminal_size: (u16, u16),\n    /// Whether space has been reserved\n    pub initialized: bool,\n}\n\nimpl InlineState {\n    pub fn new() -> Self {\n        Self {\n            origin_row: 0,\n            origin_col: 0,\n            reserved_height: 0,\n            terminal_size: (80, 24),\n            initialized: false,\n        }\n    }\n}\n```\n\n### 2.

Height Calculation for Inline Mode\n\n**File**: `lib/render_tree/tree.rs`\n\nThe key change: don't clamp height to viewport for inline Content mode.\n\n```rust\npub fn layout(&mut self, viewport_width: u16, viewport_height: u16, unclamped_height: bool) {\n    // ... existing code ...\n\n    // Height resolution with optional unclamping\n    match height_dim {\n        Some(Dimension::Fixed(h)) => {\n            root_ref.height = if unclamped_height { h } else { h.min(viewport_height) };\n        }\n        Some(Dimension::Percentage(pct)) => {\n            let calculated = (viewport_height as f32 * pct) as u16;\n            root_ref.height = calculated.max(1);\n            if !unclamped_height {\n                root_ref.height = root_ref.height.min(viewport_height);\n            }\n        }\n        Some(Dimension::Content) | None => {\n            // For Content or None, use intrinsic height\n            // Only clamp if not in unclamped mode\n            root_ref.height = if unclamped_height {\n                intrinsic_height\n            } else {\n                intrinsic_height.min(viewport_height)\n            };\n        }\n        Some(Dimension::Auto) => {\n            root_ref.height = viewport_height; // Auto still fills available space\n        }\n    }\n\n    // ... continue with layout_with_parent ...\n}\n```\n\n### 4.

Add `TerminalMode`, `InlineConfig`, `InlineHeight` enums to `config.rs`\n2. Create `inline.rs` with `InlineState` struct\n3. Add `terminal_mode` and `inline_state` fields to `App` struct\n4. Update `App::new()` to accept mode, create `App::with_mode()` and `App::inline()`\n\n### Phase 2: Space Reservation\n1. Implement `InlineState::reserve_space()` with cursor position query\n2. Implement `InlineState::expand_space()` for dynamic height growth\n3. Implement `InlineState::move_to_origin()` and `move_to_end()`\n4. Add `TerminalRenderer::clear_lines()` for line-based clearing\n\n### Phase 3: Layout Changes\n1. Add `unclamped_height: bool` parameter to `RenderTree::layout()`\n2. Modify height clamping logic to respect unclamped flag\n3. Ensure intrinsic height calculation works correctly for Content mode\n\n### Phase 4: Rendering Pipeline\n1. Implement `App::draw_inline()` method\n2. Add `TerminalRenderer::apply_updates_inline()` with origin offset\n3. Integrate space reservation into first render\n4. Handle height expansion on subsequent renders\n\n### Phase 5: Cleanup & Events\n1. Modify `Drop` implementation for inline mode cleanup\n2. Add mouse coordinate translation for inline mode\n3. Modify resize event handling (width-only for inline)\n4. Add `preserve_on_exit` behavior\n\n### Phase 6: Testing & Polish\n1. Create inline mode examples\n2. Test with various terminal emulators\n3. Handle edge cases (very small terminals, rapid resizing)\n4. Document public API\n\n---\n\n## Files to Modify\n\n| File | Changes |\n|------|---------|\n| `lib/app/config.rs` | Add `TerminalMode`, `InlineConfig`, `InlineHeight` |\n| `lib/app/inline.rs` | New file: `InlineState` implementation |\n| `lib/app/core.rs` | `App::with_mode()`, `App::inline()`, `draw_inline()`, modified `Drop` |\n| `lib/app/mod.rs` | Export new types and inline module |\n| `lib/render_tree/tree.rs` | Add `unclamped_height` parameter to `layout()` |\n| `lib/terminal.rs` | `apply_updates_inline()`, `clear_lines()` |\n| `lib/lib.rs` | Re-export `TerminalMode`, `InlineConfig`, `InlineHeight` |\n\n---\n\n## API Usage Example\n\n```rust\nuse rxtui::{App, InlineConfig, InlineHeight, TerminalMode};\n\n// Simple inline mode with defaults\nlet app = App::inline(MyComponent)?;\napp.run()?;\n\n// Custom inline configuration\nlet config = InlineConfig {\n    height: InlineHeight::Fixed(10),\n    cursor_visible: true,\n    preserve_on_exit: true,\n};\nlet app = App::with_mode(MyComponent, TerminalMode::Inline(config))?;\napp.run()?;\n\n// Content-based height with max\nlet config = InlineConfig {\n    height: InlineHeight::Content { max: Some(20) },\n    ..Default::default()\n};\nlet app = App::with_mode(MyComponent, TerminalMode::Inline(config))?;\napp.run()?;\n```\n\n---\n\n## Edge Cases & Considerations\n\n1. **Terminal too small**: If terminal height < requested inline height, clamp to available space\n2. **Cursor position query fails**: Fall back to assuming cursor is at terminal height (worst case, reserve full space)\n3. **Content shrinks**: Don't reduce reserved space (could leave gaps), just render less\n4. **Very rapid updates**: Existing double-buffering and diffing still applies\n5. **Mouse clicks outside area**: Ignore or pass through based on config\n6. **No synchronized output**: Inline mode should work without it (most terminals support)\n7. **Piped output**: Detect `!isatty()` and use simplified output mode\n"

You either work with low-level escape sequences or use immediate-mode libraries that require manual state management. **RxTUI** brings the retained-mode, component-based architecture that revolutionized web development to the terminal.\n\n- **Declarative UI** - Describe what your UI should look like, not how to change it\n- **Component Architecture** - Build complex apps from simple, reusable components\n- **Message-Based State** - Elm-inspired architecture for predictable state updates\n- **Efficient Rendering** - Virtual DOM with intelligent diffing minimizes redraws\n- **Rich Styling** - Colors, borders, flexbox-style layout, text wrapping, and more\n- **Built-in Components** - TextInput, forms, and other common UI elements\n- **Async Effects** - First-class support for timers, API calls, and background tasks\n\n## Quick Start\n\n```rust\nuse rxtui::prelude::*;\n\n#[derive(Component)]\nstruct Counter;\n\nimpl Counter {\n    #[update]\n    fn update(&self, _ctx: &Context, msg: &str, mut count: i32) -> Action {\n        match msg {\n            \"inc\" => Action::update(count + 1),\n            \"dec\" => Action::update(count - 1),\n            _ => Action::exit(),\n        }\n    }\n\n    #[view]\n    fn view(&self, ctx: &Context, count: i32) -> Node {\n        node! {\n            div(\n                pad: 2,\n                align: center,\n                w_frac: 1.0,\n                gap: 1,\n                @key(up): ctx.handler(\"inc\"),\n                @key(down): ctx.handler(\"dec\"),\n                @key(esc): ctx.handler(\"exit\")\n            ) [\n                text(format!(\"Count: {count}\"), color: white, bold),\n                text(\"use ↑/↓ to change, esc to exit\", color: bright_black)\n            ]\n        }\n    }\n}\n\nfn main() -> std::io::Result<()> {\n    App::new()?.run(Counter)\n}\n```\n\n## Features\n\n### The `node!` Macro\n\nBuild UIs declaratively with a JSX-like syntax:\n\n```rust\nnode! {\n    div(bg: black, pad: 2, border_color: white) [\n        text(\"Hello, Terminal!\", color: yellow, bold),\n\n        div(dir: horizontal, gap: 2) [\n            div(bg: blue, w: 20, h: 5) [\n                text(\"Left Panel\", color: white)\n            ],\n            div(bg: green, w: 20, h: 5) [\n                text(\"Right Panel\", color: white)\n            ]\n        ]\n    ]\n}\n```\n\n### Component System\n\nComponents manage their own state and handle messages:\n\n```rust\n#[derive(Component)]\nstruct TodoList;\n\nimpl TodoList {\n    #[update]\n    fn update(&self, ctx: &Context, msg: TodoMsg, mut state: TodoState) -> Action {\n        match msg {\n            TodoMsg::Add(item) => {\n                state.items.push(item);\n                Action::update(state)\n            }\n            TodoMsg::Remove(idx) => {\n                state.items.remove(idx);\n                Action::update(state)\n            }\n            _ => Action::none()\n        }\n    }\n\n    #[view]\n    fn view(&self, ctx: &Context, state: TodoState) -> Node {\n        // Build your UI using the current state\n    }\n}\n```\n\n### Layout System\n\nFlexbox-inspired layout with:\n- Direction control (horizontal/vertical)\n- Justify content (start, center, end, space-between, etc.)\n- Align items (start, center, end)\n- Wrapping support\n- Percentage and fixed sizing\n- Auto-sizing based on content\n\n### Rich Text Support\n\nCreate styled text with multiple segments:\n\n```rust\nnode! {\n    richtext [\n        text(\"Status: \", color: white),\n        text(\"Connected\", color: green, bold),\n        text(\" | \", color: bright_black),\n        text(\"CPU: \", color: white),\n        text(\"42%\", color: yellow)\n    ]\n}\n```\n\n### Async Effects\n\nHandle background tasks with the effects system:\n\n```rust\nuse std::time::Duration;\n\n#[derive(Component)]\nstruct Timer;\n\nimpl Timer {\n    #[effect]\n    async fn tick(&self, ctx: &Context) {\n        loop {\n            tokio::time::sleep(Duration::from_secs(1)).await;\n            ctx.send(\"tick\");\n        }\n    }\n}\n```\n\n## Examples\n\nThe [examples directory](https://github.com/microsandbox/rxtui/tree/main/examples) contains comprehensive demonstrations:\n\n- **counter** - Minimal interactive counter\n- **form** - Text input and form handling\n- **stopwatch** - Timer with effects\n- **align** - Flexbox-style alignment\n- **components** - Component composition\n- **demo** - Full feature showcase\n\nRun examples with:\n```bash\ncargo run --example counter\n```\n\n## Documentation\n\n- [API Documentation](https://docs.rs/rxtui) - Complete API reference\n- [GitHub Repository](https://github.com/microsandbox/rxtui) - Source code and issues\n- [Examples](https://github.com/microsandbox/rxtui/tree/main/examples) - Learn by example\n\n## Requirements\n\n- Rust 1.70 or later\n- Terminal with UTF-8 support\n- Unix-like system (Linux, macOS) or Windows 10+\n\n## Optional Features\n\n- `effects` (default) - Async effects support with tokio\n\n## License\n\nThis project is licensed under the Apache License 2.0 - see the [LICENSE](https://github.com/microsandbox/rxtui/blob/main/LICENSE) file for details.\n"

    "content": "//! Async effects system for running background tasks in components\n//!\n//! Effects allow components to spawn async tasks that run outside the main\n//! event loop. They can perform I/O, timers, network requests, etc. and\n//! communicate back to the UI through messages.\n//!\n//! # Quick Start\n//!\n//! The easiest way to use effects is with the `#[component]` and `#[effect]` macros:\n//!\n//! ```ignore\n//! use rxtui::prelude::*;\n//! use std::time::Duration;\n//!\n//! #[derive(Component, Clone)]\n//! struct Timer;\n//!\n//! #[component]  // Automatically collects all #[effect] methods\n//! impl Timer {\n//!     #[update]\n//!     fn update(&self, ctx: &Context, msg: TimerMsg, mut state: TimerState) -> Action {\n//!         match msg {\n//!             TimerMsg::Tick => {\n//!                 state.elapsed += 1;\n//!                 Action::update(state)\n//!             }\n//!         }\n//!     }\n//!\n//!     #[view]\n//!     fn view(&self, ctx: &Context, state: TimerState) -> Node {\n//!         node! {\n//!             div [\n//!                 text(format!(\"Elapsed: {}s\", state.elapsed))\n//!             ]\n//!         }\n//!     }\n//!\n//!     #[effect]\n//!     async fn tick(&self, ctx: &Context) {\n//!         loop {\n//!             tokio::time::sleep(Duration::from_secs(1)).await;\n//!             ctx.send(TimerMsg::Tick);\n//!         }\n//!     }\n//! }\n//! ```\n//!\n//! # How Effects Work\n//!\n//! 1. **Lifecycle**: Effects are spawned when a component mounts and cancelled when it unmounts\n//! 2. **Concurrency**: Multiple effects run concurrently in the Tokio runtime\n//! 3. **Communication**: Effects communicate with components via `ctx.send()` messages\n//! 4. **State Access**: Effects can access component state via optional state parameter\n//!\n//! # Advanced Usage\n//!\n//! ## Multiple Effects\n//!\n//! Components can have multiple effects for different concerns:\n//!\n//! ```ignore\n//! #[component]\n//! impl Dashboard {\n//!     #[effect]\n//!     async fn fetch_data(&self, ctx: &Context) {\n//!         let data = fetch_from_api().await;\n//!         ctx.send(DashboardMsg::DataLoaded(data));\n//!     }\n//!\n//!     #[effect]\n//!     async fn websocket_listener(&self, ctx: &Context) {\n//!         let mut ws = connect_websocket().await;\n//!         while let Some(msg) = ws.next().await {\n//!             ctx.send(DashboardMsg::WebSocketMessage(msg));\n//!         }\n//!     }\n//!\n//!     #[effect]\n//!     async fn auto_refresh(&self, ctx: &Context) {\n//!         loop {\n//!             tokio::time::sleep(Duration::from_secs(30)).await;\n//!             ctx.send(DashboardMsg::Refresh);\n//!         }\n//!     }\n//! }\n//! ```\n//!\n//! ## Accessing State in Effects\n//!\n//! Effects can read component state by adding a state parameter:\n//!\n//! ```ignore\n//! #[effect]\n//! async fn monitor(&self, ctx: &Context, state: AppState) {\n//!     // State is automatically fetched via ctx.get_state()\n//!     if state.threshold_exceeded() {\n//!         send_alert(&state.alert_config).await;\n//!         ctx.send(AppMsg::AlertSent);\n//!     }\n//! }\n//! ```\n//!\n//! ## Manual Implementation\n//!\n//! For full control, implement the `effects()` method manually:\n//!\n//! ```ignore\n//! impl MyComponent {\n//!     fn effects(&self, ctx: &Context) -> Vec<Effect> {\n//!         vec![\n//!             // First effect\n//!             Box::pin({\n//!                 let ctx = ctx.clone();\n//!                 async move {\n//!                     // Async logic here\n//!                 }\n//!             }),\n//!             // Second effect\n//!             Box::pin({\n//!                 let ctx = ctx.clone();\n//!                 let state = ctx.get_state::<MyState>();\n//!                 async move {\n//!                     // Async logic with state\n//!                 }\n//!             }),\n//!         ]\n//!     }\n//! }\n//! ```\n//!\n//! # Common Patterns\n//!\n//! ## Cancellable Operations\n//!\n//! Effects are automatically cancelled when components unmount, but you can\n//! also handle cancellation explicitly:\n//!\n//! ```ignore\n//! #[effect]\n//! async fn cancellable_task(&self, ctx: &Context) {\n//!     let handle = spawn_cancellable_task();\n//!\n//!     // This will be cancelled if component unmounts\n//!     tokio::select! {\n//!         result = handle => {\n//!             ctx.send(MyMsg::TaskComplete(result));\n//!         }\n//!     }\n//! }\n//! ```\n//!\n//! ## Error Handling\n//!\n//! Always handle errors gracefully in effects:\n//!\n//! ```ignore\n//! #[effect]\n//! async fn network_task(&self, ctx: &Context) {\n//!     match fetch_data().await {\n//!         Ok(data) => ctx.send(MyMsg::Success(data)),\n//!         Err(e) => ctx.send(MyMsg::Error(e.to_string())),\n//!     }\n//! }\n//! ```\n\n//--------------------------------------------------------------------------------------------------\n// Modules\n//--------------------------------------------------------------------------------------------------\n\nmod runtime;\nmod types;\n\n//--------------------------------------------------------------------------------------------------\n// Exports\n//--------------------------------------------------------------------------------------------------\n\npub use runtime::EffectRuntime;\npub use types::Effect;\n"

App::new()?.run(Counter)\n//! }\n//! ```\n//!\n//! ## Key Concepts\n//!\n//! - **Component**: Main trait for building UI components with state management\n//! - **node! macro**: Declarative macro for building UI trees with JSX-like syntax\n//! - **Node**: Virtual representation of UI elements (divs, text, components)\n//! - **Context**: Provides access to message handlers and component communication\n//! - **Action**: Return type from update methods (update state, exit, etc.)\n//! - **App**: Main application runner that manages the event loop\n//! - **VDom**: Virtual DOM that tracks UI state and calculates diffs\n//!\n//! ## Examples\n//!\n//! ### Basic Hello World\n//!\n//! ```rust,no_run\n//! use rxtui::prelude::*;\n//!\n//! #[derive(Component)]\n//! struct HelloWorld;\n//!\n//! impl HelloWorld {\n//!     #[view]\n//!     fn view(&self, ctx: &Context) -> Node {\n//!         node! {\n//!             div(bg: blue, pad: 2, @key_global(esc): ctx.handler(())) [\n//!                 text(\"Hello, Terminal!\", color: white, bold),\n//!                 text(\"Press Esc to exit\", color: white)\n//!             ]\n//!         }\n//!     }\n//! }\n//!\n//! fn main() -> std::io::Result<()> {\n//!     App::new()?.run(HelloWorld)\n//! }\n//! ```\n//!\n//! ### Using the node! Macro\n//!\n//! The `node!` macro provides a declarative way to build UI trees:\n//!\n//! ```rust\n//! use rxtui::prelude::*;\n//!\n//! fn build_ui(ctx: &Context) -> Node {\n//!     node! {\n//!         div(\n//!             bg: black,              // Background color\n//!             border_color: white,    // Border color\n//!             border_style: rounded,  // Border style\n//!             pad: 2,                 // Padding\n//!             gap: 1,                 // Gap between children\n//!             dir: vertical           // Layout direction\n//!         ) [\n//!             text(\"Title\", color: yellow, bold),\n//!\n//!             div(dir: horizontal, gap: 2) [\n//!                 div(bg: blue, w: 20, h: 5) [\n//!                     text(\"Left Panel\", color: white)\n//!                 ],\n//!                 div(bg: green, w: 20, h: 5) [\n//!                     text(\"Right Panel\", color: white)\n//!                 ]\n//!             ],\n//!\n//!             text(\"Status: Ready\", color: bright_black)\n//!         ]\n//!     }\n//! }\n//! ```\n//!\n//! ### State Management\n//!\n//! Components manage state through messages and updates:\n//!\n//! ```rust\n//! use rxtui::prelude::*;\n//!\n//! #[derive(Clone, Default)]\n//! struct TodoState {\n//!     items: Vec<String>,\n//!     input: String,\n//! }\n//!\n//! #[derive(Component)]\n//! struct TodoApp;\n//!\n//! impl TodoApp {\n//!     #[update]\n//!     fn update(&self, _ctx: &Context, msg: &str, mut state: TodoState) -> Action {\n//!         match msg {\n//!             \"add\" => {\n//!                 if !state.input.is_empty() {\n//!                     state.items.push(state.input.clone());\n//!                     state.input.clear();\n//!                 }\n//!                 Action::update(state)\n//!             }\n//!             \"clear\" => {\n//!                 state.items.clear();\n//!                 Action::update(state)\n//!             }\n//!             _ => Action::exit()\n//!         }\n//!     }\n//!\n//!     #[view]\n//!     fn view(&self, ctx: &Context, state: TodoState) -> Node {\n//!         node! {\n//!             div(pad: 2, gap: 1) [\n//!                 text(\"Todo List\", color: yellow, bold),\n//!                 div(gap: 1) [\n//!                     ...(state.items.iter().map(|item| {\n//!                         node! { text(format!(\"• {}\", item), color: white) }\n//!                     }).collect::<Vec<_>>())\n//!                 ],\n//!                 text(format!(\"{} items\", state.items.len()), color: bright_black)\n//!             ]\n//!         }\n//!     }\n//! }\n//! ```\n//!\n//! ### Async Effects\n//!\n//! Handle background tasks with effects (requires `effects` feature):\n//!\n//! ```rust\n//! use rxtui::prelude::*;\n//!\n//! #[derive(Component)]\n//! struct Timer;\n//!\n//! impl Timer {\n//!     #[update]\n//!     fn update(&self, _ctx: &Context, tick: bool, seconds: u32) -> Action {\n//!         if !tick {\n//!             return Action::exit();\n//!         }\n//!         Action::update(seconds + 1)\n//!     }\n//!\n//!     #[view]\n//!     fn view(&self, ctx: &Context, seconds: u32) -> Node {\n//!         node! {\n//!             div(pad: 2, align: center, @key(esc): ctx.handler(false)) [\n//!                 text(format!(\"Timer: {}s\", seconds), color: white, bold),\n//!                 text(\"Press Esc to stop\", color: bright_black)\n//!             ]\n//!         }\n//!     }\n//!\n//!     #[cfg(feature = \"effects\")]\n//!     #[effect]\n//!     async fn tick(&self, ctx: &Context) {\n//!         loop {\n//!             tokio::time::sleep(std::time::Duration::from_secs(1)).await;\n//!             ctx.send(true);\n//!         }\n//!     }\n//! }\n//! ```\n//!\n//! ### Rich Text Formatting\n//!\n//! Create styled text with multiple segments:\n//!\n//! ```rust\n//! use rxtui::prelude::*;\n//!\n//! fn status_line() -> Node {\n//!     node! {\n//!         richtext [\n//!             text(\"Status: \", color: white),\n//!             text(\"Connected\", color: green, bold),\n//!             text(\" | \", color: bright_black),\n//!             text(\"CPU: \", color: white),\n//!             text(\"42%\", color: yellow),\n//!             text(\" | \", color: bright_black),\n//!             text(\"Mem: \", color: white),\n//!             text(\"2.1GB\", color: cyan)\n//!         ]\n//!     }\n//! }\n//! ```\n//!\n//! ### Input Handling\n//!\n//! Use the built-in TextInput component:\n//!\n//! ```rust\n//! use rxtui::prelude::*;\n//!\n//! fn input_form(ctx: &Context) -> Node {\n//!     node! {\n//!         div(pad: 2, gap: 1) [\n//!             text(\"Enter your name:\", color: white),\n//!             input(\n//!                 placeholder: \"Type here...\",\n//!                 border_color: cyan,\n//!                 w: 30,\n//!                 focusable,\n//!                 @submit: ctx.handler(\"submit\")\n//!             )\n//!         ]\n//!     }\n//! }\n//!

This module provides the `node!` macro for composing rxtui components\n//! with an ergonomic, declarative syntax.\n//!\n//! # Overview\n//!\n//! The `node!` macro reduces boilerplate by 50-70% compared to the builder pattern\n//! while maintaining type safety and readability.\n//!\n//! # Syntax\n//!\n//! The macro uses a clean syntax:\n//! - Containers: `container(props) [children]`\n//! - Text: `text(\"content\", props)`\n//! - Components use parentheses `()` for properties\n//! - Containers use brackets `[]` for children\n//! - Event handlers use the `@` prefix\n//!\n//! # Quick Example\n//!\n//! ```ignore\n//! use rxtui::prelude::*;\n//!\n//! fn view(&self, ctx: &Context) -> Node {\n//!     node! {\n//!         container(bg: black, pad: 2) [\n//!             text(\"Hello World\", color: white, bold),\n//!             spacer(1),\n//!\n//!             container(bg: blue, w: 50) [\n//!                 text(\"Click me!\", color: white),\n//!                 @click: ctx.handler(Msg::Clicked),\n//!             ]\n//!         ]\n//!     }\n//! }\n//! ```\n//!\n//! # Color Support\n//!\n//! Colors can be specified in multiple ways:\n//! - **Named**: `red`, `blue`, `green`, `white`, `black`, etc.\n//! - **Bright variants**: `bright_red`, `bright_blue`, etc.\n//! - **Hex**: `\"#FF5733\"`, `\"#FFF\"`\n//! - **Conditional**: `(if dark { white } else { black })`\n//!\n//! # Property Shortcuts\n//!\n//! Common properties have short aliases:\n//! - `bg` → background color\n//! - `dir` → direction (vertical/v, horizontal/h)\n//! - `pad` → padding\n//! - `w` → width\n//! - `h` → height\n//! - `w_frac` → width fraction (0.0–1.0)\n//! - `h_frac` → height fraction (0.0–1.0)\n//!\n//! # Event Handlers\n//!\n//! Events use the `@` prefix:\n//! - `@click: handler` - Mouse click\n//! - `@char('q'): handler` - Character key\n//! - `@key(enter): handler` - Special key\n//! - `@char_global('q'): handler` - Global character\n//! - `@key_global(esc): handler` - Global key\n//! - `@focus: handler` - Focus gained\n//! - `@blur: handler` - Focus lost\n\nmod internal;\nmod node;\n"

{\n///     div(bg: \"#1a1a1a\", pad: 2) [\n///         // Vertical layout by default\n///         text(\"Header\", color: yellow, bold),\n///         spacer(1),\n///\n///         // Horizontal layout\n///         hstack(gap: 2) [\n///             div(bg: blue, w: 20, h: 10) [\n///                 text(\"Left\", color: white)\n///             ],\n///             div(bg: green, w: 20, h: 10) [\n///                 text(\"Right\", color: white)\n///             ]\n///         ],\n///\n///         spacer(1),\n///\n///         // Explicit vertical layout\n///         vstack [\n///             text(\"Line 1\"),\n///             text(\"Line 2\"),\n///             text(\"Line 3\")\n///         ]\n///     ]\n/// }\n/// ```\n///\n/// ## Styling Properties\n/// ```ignore\n/// node!

Automatically handles message downcasting and state management:\n\n```rust\n#[update]\nfn update(&self, ctx: &Context, msg: MyMsg, mut state: MyState) -> Action {\n    match msg {\n        MyMsg::Increment => {\n            state.count += 1;\n            Action::update(state)\n        }\n        MyMsg::Exit => Action::exit()\n    }\n}\n```\n\nThe macro automatically:\n- Downcasts incoming messages to your message type\n- Retrieves and updates component state\n- Handles multiple message types if needed\n\n#### Advanced: Multiple Message Types\n\n```rust\n#[update(msg = AppMessage, topics = [\"dialog\" => DialogMsg, \"nav\" => NavMsg])]\nfn update(&self, ctx: &Context, messages: Messages, mut state: AppState) -> Action {\n    match messages {\n        Messages::AppMessage(msg) => {\n            // Handle app messages\n            Action::update(state)\n        }\n        Messages::DialogMsg(msg) => {\n            // Handle dialog messages from \"dialog\" topic\n            Action::update(state)\n        }\n        Messages::NavMsg(msg) => {\n            // Handle navigation messages from \"nav\" topic\n            Action::update(state)\n        }\n    }\n}\n```\n\nThe macro generates an enum `Messages` with variants for each message type.\n\n#### Topic-Based Updates\n\n```rust\n#[update(\"navigation\")]\nfn handle_nav(&self, ctx: &Context, msg: NavMsg, state: State) -> Action {\n    // Handle navigation messages\n}\n\n#[update(\"user\")]\nfn handle_user(&self, ctx: &Context, msg: UserMsg, state: State) -> Action {\n    // Handle user messages\n}\n```\n\n### `#[view]`\n\nMarks a method as the component's view renderer:\n\n```rust\n#[view]\nfn view(&self, ctx: &Context, state: MyState) -> Node {\n    node! {\n        div(bg: black, pad: 2) [\n            text(format!(\"Count: {}\", state.count))\n        ]\n    }\n}\n```\n\nThe macro automatically:\n- Retrieves the current component state\n- Passes it to your view function\n- Returns the rendered node tree\n\n### `#[effect]`\n\nCreates async background tasks (requires `effects` feature):\n\n```rust\n#[effect]\nasync fn tick(&self, ctx: &Context) {\n    loop {\n        tokio::time::sleep(Duration::from_secs(1)).await;\n        ctx.send(\"tick\");\n    }\n}\n```\n\nEffects run automatically when the component is mounted and are cancelled when unmounted.\n\n## Complete Example\n\n```rust\nuse rxtui::prelude::*;\nuse std::time::Duration;\n\n#[derive(Debug, Clone)]\nenum CounterMsg {\n    Increment,\n    Decrement,\n    Reset,\n    Exit,\n}\n\n#[derive(Debug, Clone, Default)]\nstruct CounterState {\n    count: i32,\n}\n\n#[derive(Component)]\nstruct Counter;\n\nimpl Counter {\n    #[update]\n    fn update(&self, _ctx: &Context, msg: CounterMsg, mut state: CounterState) -> Action {\n        match msg {\n            CounterMsg::Increment => {\n                state.count += 1;\n                Action::update(state)\n            }\n            CounterMsg::Decrement => {\n                state.count -= 1;\n                Action::update(state)\n            }\n            CounterMsg::Reset => {\n                state.count = 0;\n                Action::update(state)\n            }\n            CounterMsg::Exit => Action::exit()\n        }\n    }\n\n    #[view]\n    fn view(&self, ctx: &Context, state: CounterState) -> Node {\n        node! {\n            div(\n                bg: black,\n                pad: 2,\n                @key(up): ctx.handler(CounterMsg::Increment),\n                @key(down): ctx.handler(CounterMsg::Decrement),\n                @key(r): ctx.handler(CounterMsg::Reset),\n                @key(esc): ctx.handler(CounterMsg::Exit)\n            ) [\n                text(format!(\"Count: {}\", state.count), color: white, bold),\n                text(\"↑/↓: change | r: reset | esc: exit\", color: bright_black)\n            ]\n        }\n    }\n\n    #[cfg(feature = \"effects\")]\n    #[effect]\n    async fn auto_increment(&self, ctx: &Context) {\n        loop {\n            tokio::time::sleep(Duration::from_secs(5)).await;\n            ctx.send(CounterMsg::Increment);\n        }\n    }\n}\n\nfn main() -> std::io::Result<()> {\n    App::new()?.run(Counter)\n}\n```\n\n## Documentation\n\nFor complete documentation and more examples, see the main [RxTUI documentation](https://docs.rs/rxtui).\n\n## License\n\nThis project is licensed under the Apache License 2.0 - see the [LICENSE](https://github.com/microsandbox/rxtui/blob/main/LICENSE) file for details.\n"
