-## v0.28.0
+## Unreleased (0.30.0)
+
+### `FrameExt` trait for `unstable-widget-ref` feature ([#1530])
+
+[#1530]: https://github.com/ratatui/ratatui/pull/1530
+
+To call `Frame::render_widget_ref()` or `Frame::render_stateful_widget_ref()` you now need to:
+
+1. Import the `FrameExt` trait from `ratatui::widgets`.
+2. Enable the `unstable-widget-ref` feature.
+
+For example:
+
+```rust
+use ratatui::{
+    layout::Rect,
+    widgets::{Block, FrameExt},
+};
+
+let block = Block::new();
+let area = Rect::new(0, 0, 5, 5);
+frame.render_widget_ref(&block, area);
+```
+
+### `WidgetRef` no longer has a blanket implementation of Widget
+
+Previously there was a blanket implementation of Widget for WidgetRef. This has been reversed to
+instead be a blanket implementation of WidgetRef for all &W where W: Widget. Any widgets that
+previously implemented WidgetRef directly should now instead implement Widget for a reference to the
+type.
+
+```diff
+-impl WidgetRef for Foo {
+-    fn render_ref(&self, area: Rect, buf: &mut Buffer)
++impl Widget for &Foo {
++    fn render(self, area: Rect, buf: &mut Buffer)
+}
+```
+
+### The `From` impls for backend types are now replaced with more specific traits [#1464]
+
+[#1464]: https://github.com/ratatui/ratatui/pull/1464
+
+Crossterm gains `ratatui::backend::crossterm::{FromCrossterm, IntoCrossterm}`
+Termwiz gains `ratatui::backend::termwiz::{FromTermwiz, IntoTermwiz}`
+
+This is necessary in order to avoid the orphan rule when implementing `From` for crossterm types
+once the crossterm types are moved to a separate crate.
+
+```diff
++ use ratatui::backend::crossterm::{FromCrossterm, IntoCrossterm};
+
+let crossterm_color = crossterm::style::Color::Black;
+- let ratatui_color = crossterm_color.into();
+- let ratatui_color = ratatui::style::Color::from(crossterm_color);
++ let ratatui_color = ratatui::style::Color::from_crossterm(crossterm_color);
+- let crossterm_color = ratatui_color.into();
+- let crossterm_color = crossterm::style::Color::from(ratatui_color);
++ let crossterm_color = ratatui_color.into_crossterm();
+
+let crossterm_attribute = crossterm::style::types::Attribute::Bold;
+- let ratatui_modifier = crossterm_attribute.into();
+- let ratatui_modifier = ratatui::style::Modifier::from(crossterm_attribute);
++ let ratatui_modifier = ratatui::style::Modifier::from_crossterm(crossterm_attribute);
+- let crossterm_attribute = ratatui_modifier.into();
+- let crossterm_attribute = crossterm::style::types::Attribute::from(ratatui_modifier);
++ let crossterm_attribute = ratatui_modifier.into_crossterm();
+```
+
+Similar conversions for `ContentStyle` -> `Style` and `Attributes` -> `Modifier` exist for
+Crossterm and the various Termion and Termwiz types as well.
+
+### `Bar::label()` and `BarGroup::label()` now accepts `Into<Line<'a>>`. ([#1471])
+
+[#1471]: https://github.com/ratatui/ratatui/pull/1471
+
+Previously `Bar::label()` and `BarGroup::label()` accepted `Line<'a>`, but they now accepts `Into<Line<'a>>`.
+
+for `Bar::label()`:
+
+```diff
+- Bar::default().label("foo".into());
++ Bar::default().label("foo");
+```
+
+for `BarGroup::label()`:
+
+```diff
+- BarGroup::default().label("bar".into());
++ BarGroup::default().label("bar");
+```
+
+### `Bar::text_value` now accepts `Into<String>` ([#1471])
+
+Previously `Bar::text_value` accepted `String`, but now it accepts `Into<String>`.
+
+for `Bar::text_value()`:
+
+```diff
+- Bar::default().text_value("foobar".into());
++ Bar::default().text_value("foobar");
+```
+
+## [v0.29.0](https://github.com/ratatui/ratatui/releases/tag/v0.29.0)
+
+### `Sparkline::data` takes `IntoIterator<Item = SparklineBar>` instead of `&[u64]` and is no longer const ([#1326])
+
+[#1326]: https://github.com/ratatui/ratatui/pull/1326
+
+The `Sparkline::data` method has been modified to accept `IntoIterator<Item = SparklineBar>`
+instead of `&[u64]`.
+
+`SparklineBar` is a struct that contains an `Option<u64>` value, which represents an possible
+_absent_ value, as distinct from a `0` value. This change allows the `Sparkline` to style
+data points differently, depending on whether they are present or absent.
+
+`SparklineBar` also contains an `Option<Style>` that will be used to apply a style the bar in
+addition to any other styling applied to the `Sparkline`.
+
+Several `From` implementations have been added to `SparklineBar` to support existing callers who
+provide `&[u64]` and other types that can be converted to `SparklineBar`, such as `Option<u64>`.
+
+If you encounter any type inference issues, you may need to provide an explicit type for the data
+passed to `Sparkline::data`. For example, if you are passing a single value, you may need to use
+`into()` to convert it to form that can be used as a `SparklineBar`:
+
+```diff
+let value = 1u8;
+- Sparkline::default().data(&[value.into()]);
++ Sparkline::default().data(&[u64::from(value)]);
+```
+
+As a consequence of this change, the `data` method is no longer a `const fn`.
+
+### `Color::from_hsl` is now behind the `palette` feature and accepts `palette::Hsl` ([#1418])
+
+[#1418]: https://github.com/ratatui/ratatui/pull/1418
+
+Previously `Color::from_hsl` accepted components as individual f64 parameters. It now accepts a
+single `palette::Hsl` value and is gated behind a `palette` feature flag.
+
+```diff
+- Color::from_hsl(360.0, 100.0, 100.0)
++ Color::from_hsl(Hsl::new(360.0, 100.0, 100.0))
+```
+
+### Removed public fields from `Rect` iterators ([#1358], [#1424])
+
+[#1358]: https://github.com/ratatui/ratatui/pull/1358
+[#1424]: https://github.com/ratatui/ratatui/pull/1424
+
+The `pub` modifier has been removed from fields on the `Columns`,`Rows`, and `Positions` iterators.
+These fields were not intended to be public and should not have been accessed directly.
+
+### `Rect::area()` now returns u32 instead of u16 ([#1378])
+
+[#1378]: https://github.com/ratatui/ratatui/pull/1378
+
+This is likely to impact anything which relies on `Rect::area` maxing out at u16::MAX. It can now
+return up to u16::MAX * u16::MAX (2^32 - 2^17 + 1).
+
+### `Line` now implements `From<Cow<str>` ([#1373])
+
+[#1373]: https://github.com/ratatui/ratatui/pull/1373
+
+As this adds an extra conversion, ambiguous inferred expressions may no longer compile.
+
+```rust
+// given:
+struct Foo { ... }
+impl From<Foo> for String { ... }
+impl From<Foo> for Cow<str> { ... }
+
+let foo = Foo { ... };
+let line = Line::from(foo); // now fails due to now ambiguous inferred type
+// replace with e.g.
+let line = Line::from(String::from(foo));
+```
+
+### `Tabs::select()` now accepts `Into<Option<usize>>` ([#1413])
+
+[#1413]: https://github.com/ratatui/ratatui/pull/1413
+
+Previously `Tabs::select()` accepted `usize`, but it now accepts `Into<Option<usize>>`. This breaks
+any code already using parameter type inference:
+
+```diff
+let selected = 1u8;
+- let tabs = Tabs::new(["A", "B"]).select(selected.into())
++ let tabs = Tabs::new(["A", "B"]).select(selected as usize)
+```
+
+### `Table::highlight_style` is now `Table::row_highlight_style` ([#1331])
+
+[#1331]: https://github.com/ratatui/ratatui/pull/1331
+
+The `Table::highlight_style` is now deprecated in favor of `Table::row_highlight_style`.
+
+Also, the serialized output of the `TableState` will now include the "selected_column" field.
+Software that manually parse the serialized the output (with anything other than the `Serialize`
+implementation on `TableState`) may have to be refactored if the "selected_column" field is not
+accounted for. This does not affect users who rely on the `Deserialize`, or `Serialize`
+implementation on the state.

+## [0.30.0-alpha.1](https://github.com/ratatui/ratatui/releases/tag/0.30.0-alpha.1) - 2025-01-14
+
+0.30.0-alpha.1 is a pre-release of the upcoming 0.30.0 release. It is intended for testing and
+feedback. Please report any issues you encounter. The primary change is that we've split the crate
+into multiple crates. The main crate is now `ratatui-core` and the widgets are in `ratatui-widgets`.
+This allows for widget crates to depend on a stable core crate, and for the core crate to be used
+without widgets.

+
+  > The current implementation of Terminal::insert_before causes the
+  > viewport to flicker. This is described in #584 .
+  >
+  > This PR removes that flickering by using terminal scrolling regions
+  > (sometimes called "scroll regions"). A terminal can have its scrolling
+  > region set to something other than the whole screen. When a scroll ANSI
+  > sequence is sent to the terminal and it has a non-default scrolling
+  > region, the terminal will scroll just inside of that region.
+  >
+  > We use scrolling regions to implement insert_before. We create a region
+  > on the screen above the viewport, scroll that up to make room for the
+  > newly inserted lines, and then draw the new lines. We may need to repeat
+  > this process depending on how much space there is and how many lines we
+  > need to draw.
+  >
+  > When the viewport takes up the entire screen, we take a modified
+  > approach. We create a scrolling region of just the top line (could be
+  > more) of the viewport, then use that to draw the lines we want to
+  > output. When we're done, we scroll it up by one line, into the
+  > scrollback history, and then redraw the top line from the viewport.
+  >
+  > A final edge case is when the viewport hasn't yet reached the bottom of
+  > the screen. This case, we set up a different scrolling region, where the
+  > top is the top of the viewport, and the bottom is the viewport's bottom
+  > plus the number of lines we want to scroll by. We then scroll this
+  > region down to open up space above the viewport for drawing the inserted
+  > lines.
+  >
+  > Regardless of what we do, we need to reset the scrolling region. This PR
+  > takes the approach of always resetting the scrolling region after every
+  > operation. So the Backend gets new scroll_region_up and
+  > scroll_region_down methods instead of set_scrolling_region, scroll_up,
+  > scroll_down, and reset_scrolling_region methods. We chose that approach
+  > for two reasons. First, we don't want Ratatui to have to remember that
+  > state and then reset the scrolling region when tearing down. Second, the
+  > pre-Windows-10 console code doesn't support scrolling region
+  >
+  > This PR:
+  > - Adds a new scrolling-regions feature.
+  > - Adds two new Backend methods: scroll_region_up and scroll_region_down.
+  > - Implements those Backend methods on all backends in the codebase.
+  > - The crossterm and termion implementations use raw ANSI escape
+  > sequences. I'm trying to merge changes into those two projects
+  > separately to support these functions.
+  > - Adds code to Terminal::insert_before to choose between
+  > insert_before_scrolling_regions and insert_before_no_scrolling_regions.
+  > The latter is the old implementation.
+  > - Adds lots of tests to the TestBackend to for the
+  > scrolling-region-related Backend methods.
+  > - Adds versions of terminal tests that show that insert_before doesn't
+  > clobber the viewport. This is a change in behavior from before.

-# Ratatui
-
-[Ratatui][Ratatui Website] is a crate for cooking up terminal user interfaces in Rust. It is a
-lightweight library that provides a set of widgets and utilities to build complex Rust TUIs.
-Ratatui was forked from the [tui-rs] crate in 2023 in order to continue its development.
-
-## Installation
-
-Add `ratatui` as a dependency to your cargo.toml:
-
-```shell
-cargo add ratatui
-```
-
-Ratatui uses [Crossterm] by default as it works on most platforms. See the [Installation]
-section of the [Ratatui Website] for more details on how to use other backends ([Termion] /
-[Termwiz]).
-
-## Introduction
-
-Ratatui is based on the principle of immediate rendering with intermediate buffers. This means
-that for each frame, your app must render all widgets that are supposed to be part of the UI.
-This is in contrast to the retained mode style of rendering where widgets are updated and then
-automatically redrawn on the next frame. See the [Rendering] section of the [Ratatui Website]
-for more info.
-
-You can also watch the [FOSDEM 2024 talk] about Ratatui which gives a brief introduction to
-terminal user interfaces and showcases the features of Ratatui, along with a hello world demo.
-

+[Ratatui][Ratatui Website] (_ˌræ.təˈtu.i_) is a Rust crate for cooking up terminal user interfaces
+(TUIs). It provides a simple and flexible way to create text-based user interfaces in the terminal,
+which can be used for command-line applications, dashboards, and other interactive console programs.
 
 ## Quickstart
 
-The following example demonstrates the minimal amount of code necessary to setup a terminal and
-render "Hello World!". The full code for this example which contains a little more detail is in
-the [Examples] directory. For more guidance on different ways to structure your application see
-the [Application Patterns] and [Hello World tutorial] sections in the [Ratatui Website] and the
-various [Examples]. There are also several starter templates available in the [templates]
-repository.
+Ratatui has [templates] available to help you get started quickly. You can use the
+[`cargo-generate`] command to create a new project with Ratatui:
 
-Every application built with `ratatui` needs to implement the following steps:
+```shell
+cargo install --locked cargo-generate
+cargo generate ratatui/templates
+```
 
-- Initialize the terminal
-- A main loop to:
-  - Handle input events
-  - Draw the UI
-- Restore the terminal state
-
-The library contains a [`prelude`] module that re-exports the most commonly used traits and
-types for convenience. Most examples in the documentation will use this instead of showing the
-full path of each type.
-
-### Initialize and restore the terminal
-
-The [`Terminal`] type is the main entry point for any Ratatui application. It is a light
-abstraction over a choice of [`Backend`] implementations that provides functionality to draw
-each frame, clear the screen, hide the cursor, etc. It is parametrized over any type that
-implements the [`Backend`] trait which has implementations for [Crossterm], [Termion] and
-[Termwiz].
-
-Most applications should enter the Alternate Screen when starting and leave it when exiting and
-also enable raw mode to disable line buffering and enable reading key events. See the [`backend`
-module] and the [Backends] section of the [Ratatui Website] for more info.
-
-### Drawing the UI
-
-The drawing logic is delegated to a closure that takes a [`Frame`] instance as argument. The
-[`Frame`] provides the size of the area to draw to and allows the app to render any [`Widget`]
-using the provided [`render_widget`] method. After this closure returns, a diff is performed and
-only the changes are drawn to the terminal. See the [Widgets] section of the [Ratatui Website]
-for more info.
-
-### Handling events
-
-Ratatui does not include any input handling. Instead event handling can be implemented by
-calling backend library methods directly. See the [Handling Events] section of the [Ratatui
-Website] for more info. For example, if you are using [Crossterm], you can use the
-[`crossterm::event`] module to handle events.
-
-### Example
+Selecting the Hello World template produces the following application:
 
 ```rust
-use std::io::{self, stdout};
+use color_eyre::Result;
+use crossterm::event::{self, Event};
+use ratatui::{DefaultTerminal, Frame};
 
-use ratatui::{
-    backend::CrosstermBackend,
-    crossterm::{
-        event::{self, Event, KeyCode},
-        terminal::{
-            disable_raw_mode, enable_raw_mode, EnterAlternateScreen, LeaveAlternateScreen,
-        },
-        ExecutableCommand,
-    },
-    widgets::{Block, Paragraph},
-    Frame, Terminal,
-};
-
-fn main() -> io::Result<()> {
-    enable_raw_mode()?;
-    stdout().execute(EnterAlternateScreen)?;
-    let mut terminal = Terminal::new(CrosstermBackend::new(stdout()))?;
-
-    let mut should_quit = false;
-    while !should_quit {
-        terminal.draw(ui)?;
-        should_quit = handle_events()?;
-    }
-
-    disable_raw_mode()?;
-    stdout().execute(LeaveAlternateScreen)?;
-    Ok(())
+fn main() -> Result<()> {
+    color_eyre::install()?;
+    let terminal = ratatui::init();
+    let result = run(terminal);
+    ratatui::restore();
+    result
 }
 
-fn handle_events() -> io::Result<bool> {
-    if event::poll(std::time::Duration::from_millis(50))? {
-        if let Event::Key(key) = event::read()? {
-            if key.kind == event::KeyEventKind::Press && key.code == KeyCode::Char('q') {
-                return Ok(true);
-            }
+fn run(mut terminal: DefaultTerminal) -> Result<()> {
+    loop {
+        terminal.draw(render)?;
+        if matches!(event::read()?, Event::Key(_)) {
+            break Ok(());
         }
     }
-    Ok(false)
 }
 
-fn ui(frame: &mut Frame) {
-    frame.render_widget(
-        Paragraph::new("Hello World!").block(Block::bordered().title("Greeting")),
-        frame.area(),
-    );
+fn render(frame: &mut Frame) {
+    frame.render_widget("hello world", frame.area());
 }
 ```

-## Layout
+You can also watch the [EuroRust 2024 talk] to learn about common concepts in Ratatui and what's
+possible to build with it.
 
-The library comes with a basic yet useful layout management object called [`Layout`] which
-allows you to split the available space into multiple areas and then render widgets in each
-area. This lets you describe a responsive terminal UI by nesting layouts. See the [Layout]
-section of the [Ratatui Website] for more info.
+## Templates
 
-```rust
-use ratatui::{
-    layout::{Constraint, Layout},
-    widgets::Block,
-    Frame,
-};
+If you're looking to get started quickly, you can use one of the available templates from the
+[templates] repository using [`cargo-generate`]:
 
-fn ui(frame: &mut Frame) {
-    let [title_area, main_area, status_area] = Layout::vertical([
-        Constraint::Length(1),
-        Constraint::Min(0),
-        Constraint::Length(1),
-    ])
-    .areas(frame.area());
-    let [left_area, right_area] =
-        Layout::horizontal([Constraint::Percentage(50), Constraint::Percentage(50)])
-            .areas(main_area);
-
-    frame.render_widget(Block::bordered().title("Title Bar"), title_area);
-    frame.render_widget(Block::bordered().title("Status Bar"), status_area);
-    frame.render_widget(Block::bordered().title("Left"), left_area);
-    frame.render_widget(Block::bordered().title("Right"), right_area);
-}
+```shell
+cargo generate ratatui/templates
 ```

-## Text and styling
-
-The [`Text`], [`Line`] and [`Span`] types are the building blocks of the library and are used in
-many places. [`Text`] is a list of [`Line`]s and a [`Line`] is a list of [`Span`]s. A [`Span`]
-is a string with a specific style.
-
-The [`style` module] provides types that represent the various styling options. The most
-important one is [`Style`] which represents the foreground and background colors and the text
-attributes of a [`Span`]. The [`style` module] also provides a [`Stylize`] trait that allows
-short-hand syntax to apply a style to widgets and text. See the [Styling Text] section of the
-[Ratatui Website] for more info.
-
-```rust
-use ratatui::{
-    layout::{Constraint, Layout},
-    style::{Color, Modifier, Style, Stylize},
-    text::{Line, Span},
-    widgets::{Block, Paragraph},
-    Frame,
-};
-
-fn ui(frame: &mut Frame) {
-    let areas = Layout::vertical([Constraint::Length(1); 4]).split(frame.area());
-
-    let line = Line::from(vec![
-        Span::raw("Hello "),
-        Span::styled(
-            "World",
-            Style::new()
-                .fg(Color::Green)
-                .bg(Color::White)
-                .add_modifier(Modifier::BOLD),
-        ),
-        "!".red().on_light_yellow().italic(),
-    ]);
-    frame.render_widget(line, areas[0]);
-
-    // using the short-hand syntax and implicit conversions
-    let paragraph = Paragraph::new("Hello World!".red().on_white().bold());
-    frame.render_widget(paragraph, areas[1]);
-
-    // style the whole widget instead of just the text
-    let paragraph = Paragraph::new("Hello World!").style(Style::new().red().on_white());
-    frame.render_widget(paragraph, areas[2]);
-
-    // use the simpler short-hand syntax
-    let paragraph = Paragraph::new("Hello World!").blue().on_yellow();
-    frame.render_widget(paragraph, areas[3]);

-## Widgets
-
-### Built in
-
-The library comes with the following
-[widgets](https://docs.rs/ratatui/latest/ratatui/widgets/index.html):
-
-- [BarChart](https://docs.rs/ratatui/latest/ratatui/widgets/struct.BarChart.html)

-## Design choices
+## Demo
 
-The examples contain some opinionated choices in order to make it easier for newer rustaceans to
-easily be productive in creating applications:
+This is the original demo example from the main README. It is available for each of the backends.
+[Source](./apps/demo/).
 
-- Each example has an App struct, with methods that implement a main loop, handle events and drawing
-  the UI.
-- We use color_eyre for handling errors and panics. See [How to use color-eyre with Ratatui] on the
-  website for more information about this.
-- Common code is not extracted into a separate file. This makes each example self-contained and easy
-  to read as a whole.
-
-Not every example has been updated with all these points in mind yet, however over time they will
-be. None of the above choices are strictly necessary for Ratatui apps, but these choices make
-examples easier to run, maintain and explain. These choices are designed to help newer users fall
-into the pit of success when incorporating example code into their own apps. We may also eventually
-move some of these design choices into the core of Ratatui to simplify apps.

-## How to update these examples
-
-These gifs were created using [VHS](https://github.com/charmbracelet/vhs). Each example has a
-corresponding `.tape` file that holds instructions for how to generate the images. Note that the
-images themselves are stored in a separate `images` git branch to avoid bloating the main
-repository.
-
-<!--
-
-Links to images to make them easier to update in bulk. Use the following script to update and upload
-the examples to the images branch. (Requires push access to the branch).
-
-```shell

+# Input Form example
+
+This example demonstrates how to handle input across several form fields (2 strings and an number).
+It uses an enum to track the focused field, and sends keyboard events to one which is current.
+
+Run this example with:
+
+```shell
+cargo run -p input-form
+```
+
+This example does not handle things like cursor movement within the line (just keys and backspace).
+Most apps would benefit from using the following crates for text input rather than directly using
+strings:
+
+- [`tui-input`](https://crates.io/crates/tui-input)
+- [`tui-prompts`](https://crates.io/crates/tui-prompts)
+- [`tui-textarea`](https://crates.io/crates/tui-textarea)
+- [`rat-salsa`](https://crates.io/crates/rat-salsa)
+
+Some more ideas for handling focus can be found in:
+
+- [`focusable`](https://crates.io/crates/focusable) (see also [Ratatui forum
+  post](https://forum.ratatui.rs/t/focusable-crate-manage-focus-state-for-your-widgets/73))
+- [`rat-focus`](https://crates.io/crates/rat-focus)
+- A useful [`Bevy` discssion](https://github.com/bevyengine/bevy/discussions/15374) about focus
+  more generally.

+
+**ratatui-core** is the core library of the [ratatui] project,
+providing the essential building blocks for creating rich terminal user interfaces in Rust.
+
+[ratatui]: https://github.com/ratatui/ratatui
+
+### Why `ratatui-core`?
+
+The `ratatui-core` crate is split from the main [`ratatui`](https://crates.io/crates/ratatui) crate
+to offer better stability for widget library authors. Widget libraries should generally depend
+on `ratatui-core`, benefiting from a stable API and reducing the need for frequent updates.
+
+Applications, on the other hand, should depend on the main `ratatui` crate, which includes
+built-in widgets and additional features.
+
+## Installation
+
+Add `ratatui-core` to your `Cargo.toml`:
+
+```shell
+cargo add ratatui-core
+```
+
+## Contributing
+
+We welcome contributions from the community! Please see our [CONTRIBUTING](../CONTRIBUTING.md)
+guide for more details on how to get involved.

+//! **ratatui-core** is the core library of the [ratatui] project,
+//! providing the essential building blocks for creating rich terminal user interfaces in Rust.
+//!
+//! [ratatui]: https://github.com/ratatui/ratatui
+//!
+//! ## Why `ratatui-core`?
+//!
+//! The `ratatui-core` crate is split from the main [`ratatui`](https://crates.io/crates/ratatui) crate
+//! to offer better stability for widget library authors. Widget libraries should generally depend
+//! on `ratatui-core`, benefiting from a stable API and reducing the need for frequent updates.
+//!
+//! Applications, on the other hand, should depend on the main `ratatui` crate, which includes
+//! built-in widgets and additional features.
+//!
+//! # Installation
+//!
+//! Add `ratatui-core` to your `Cargo.toml`:
+//!
+//! ```shell
+//! cargo add ratatui-core
+//! ```
