chore(release): prepare for 0.28.1 (#1343) 
🧀 

The current release steps in reference to #1337

- Bump version in `Cargo.toml`
- `git cliff -u -p CHANGELOG.md -t v0.28.1`
- Merge the PR
- `git tag v0.28.1`
- `git push origin v0.28.1`

We can probably automate away most of these with `release-plz` when it
fully supports `git-cliff`'s GitHub integration.

## [v0.28.1](https://github.com/ratatui/ratatui/releases/tag/v0.28.1) - 2024-08-25
### Features
- [ed51c4b](https://github.com/ratatui/ratatui/commit/ed51c4b3429862201b2c5de6846fea4c237f0ffb) *(terminal)* Add ratatui::init() and restore() methods by @joshka in [#1289](https://github.com/ratatui/ratatui/pull/1289)
> These are simple opinionated methods for creating a terminal that is
> useful to use in most apps. The new init method creates a crossterm
> backend writing to stdout, enables raw mode, enters the alternate
> screen, and sets a panic handler that restores the terminal on panic.
>
> A minimal hello world now looks a bit like:
>
> ```rust
> use ratatui::{
> crossterm::event::{self, Event},
> text::Text,
> Frame,
> };
>
> fn main() {
> let mut terminal = ratatui::init();
> loop {
> terminal
> .draw(|frame: &mut Frame| frame.render_widget(Text::raw("Hello World!"), frame.area()))
> .expect("Failed to draw");
> if matches!(event::read().expect("failed to read event"), Event::Key(_)) {
> break;
> }
> }
> ratatui::restore();
> }
> ```
>
> A type alias `DefaultTerminal` is added to represent this terminal
> type and to simplify any cases where applications need to pass this
> terminal around. It is equivalent to:
> `Terminal<CrosstermBackend<Stdout>>`
>
> We also added `ratatui::try_init()` and `try_restore()`, for situations
> where you might want to handle initialization errors yourself instead
> of letting the panic handler fire and cleanup. Simple Apps should
> prefer the `init` and `restore` functions over these functions.
>
> Corresponding functions to allow passing a `TerminalOptions` with
> a `Viewport` (e.g. inline, fixed) are also available
> (`init_with_options`,
> and `try_init_with_options`).
>
> The existing code to create a backend and terminal will remain and
> is not deprecated by this approach. This just provides a simple one
> line initialization using the common options.

### Bug Fixes
- [aed60b9](https://github.com/ratatui/ratatui/commit/aed60b98394edc834d9fe8e96c3698510b5922f4) *(terminal)* Terminal::insert_before would crash when called while the viewport filled the screen by @nfachan in [#1329](https://github.com/ratatui/ratatui/pull/1329)
> Reimplement Terminal::insert_before. The previous implementation would
> insert the new lines in chunks into the area between the top of the
> screen and the top of the (new) viewport. If the viewport filled the
> screen, there would be no area in which to insert lines, and the
> function would crash.
>
> The new implementation uses as much of the screen as it needs to, all
> the way up to using the whole screen.
>
> This commit:
> - adds a scrollback buffer to the `TestBackend` so that tests can
> inspect and assert the state of the scrollback buffer in addition to the
> screen
> - adds functions to `TestBackend` to assert the state of the scrollback
> - adds and updates `TestBackend` tests to test the behavior of the
> scrollback and the new asserting functions
> - reimplements `Terminal::insert_before`, including adding two new
> helper functions `Terminal::draw_lines` and `Terminal::scroll_up`.
> - updates the documentation for `Terminal::insert_before` to clarify
> some of the edge cases
> - updates terminal tests to assert the state of the scrollback buffer
> - adds a new test for the condition that causes the bug
> - adds a conversion constructor `Cell::from(char)`

> If the amount of characters in the screen above the viewport was greater
> than u16::MAX, a multiplication would overflow. The multiply was used to
> compute the maximum chunk size. The fix is to just do the multiplication
> as a usize and also do the subsequent division as a usize.
>
> There is currently another outstanding issue that limits the amount of
> characters that can be inserted when calling Terminal::insert_before to
> u16::MAX. However, this bug can still occur even if the viewport and the
> amount of characters being inserted are both less than u16::MAX, since
> it's dependant on how large the screen is above the viewport.

**Full Changelog**: https://github.com/ratatui/ratatui/compare/v0.28.0...v0.28.1
## [0.28.0](https://github.com/ratatui/ratatui/releases/tag/v0.28.0) - 2024-08-07
_"If you are what you eat, then I only want to eat the good stuff." – Remy_
We are excited to announce the new version of `ratatui` - a Rust library that's all about cooking up TUIs 🐭
In this version, we have upgraded to Crossterm 0.28.0, introducing enhanced functionality and performance improvements.
New features include GraphType::Bar, lines in bar charts, and enhanced scroll/navigation methods.
We have also refined the terminal module and added brand new methods for cursor positions and text operations.
✨ **Release highlights**: <https://ratatui.rs/highlights/v028/>
⚠️ List of breaking changes can be found [here](https://github.com/ratatui/ratatui/blob/main/BREAKING-CHANGES.md).

- [a23ecd9](https://github.com/ratatui/ratatui/commit/a23ecd9b456ab2aa4dc858fe31461a6224b40fe3) _(buffer)_ Add Buffer::cell, cell_mut and index implementations by @joshka in [#1084](https://github.com/ratatui/ratatui/pull/1084)
> Code which previously called `buf.get(x, y)` or `buf.get_mut(x, y)`
> should now use index operators, or be transitioned to `buff.cell()` or
> `buf.cell_mut()` for safe access that avoids panics by returning
> `Option<&Cell>` and `Option<&mut Cell>`.
>
> The new methods accept `Into<Position>` instead of `x` and `y`
> coordinates, which makes them more ergonomic to use.
>
> ```rust
> let mut buffer = Buffer::empty(Rect::new(0, 0, 10, 10));
>
> let cell = buf[(0, 0)];
> let cell = buf[Position::new(0, 0)];
>
> let symbol = buf.cell((0, 0)).map(|cell| cell.symbol());
> let symbol = buf.cell(Position::new(0, 0)).map(|cell| cell.symbol());
>
> buf[(0, 0)].set_symbol("🐀");
> buf[Position::new(0, 0)].set_symbol("🐀");
>
> buf.cell_mut((0, 0)).map(|cell| cell.set_symbol("🐀"));
> buf.cell_mut(Position::new(0, 0)).map(|cell| cell.set_symbol("🐀"));
> ```
>
> The existing `get()` and `get_mut()` methods are marked as deprecated.
> These are fairly widely used and we will leave these methods around on
> the buffer for a longer time than our normal deprecation approach (2
> major release)

**Full Changelog**: <https://github.com/ratatui/ratatui/compare/v0.27.0...0.28.0>
## [0.27.0](https://github.com/ratatui/ratatui/releases/tag/v0.27.0) - 2024-06-24
In this version, we have focused on enhancing usability and functionality with new features like
background styles for LineGauge, palette colors, and various other improvements including
improved performance. Also, we added brand new examples for tracing and creating hyperlinks!
✨ **Release highlights**: <https://ratatui.rs/highlights/v027/>
⚠️ List of breaking changes can be found [here](https://github.com/ratatui/ratatui/blob/main/BREAKING-CHANGES.md).

```text
This PR deprecates `gauge_style` in favor of `filled_style` and
`unfilled_style` which can have its foreground and background styled.

`border::FULL` uses a full block symbol, while `border::EMPTY` uses an
empty space. This is useful for when you need to allocate space for the
border and apply the border style to a block without actually drawing a
border. This makes it possible to style the entire title area or a block
rather than just the title content.
```rust
use ratatui::{symbols::border, widgets::Block};
let block = Block::bordered().title("Title").border_set(border::FULL);
let block = Block::bordered().title("Title").border_set(border::EMPTY);
```

Fixes:<https://github.com/ratatui/ratatui/pull/1159>
BREAKING CHANGE:The `List` widget now clamps the selected index to the

This is behind the "palette" feature flag.

use ratatui::style::Color;
let color = Color::from(Srgb::new(1.0f32, 0.0, 0.0));

```text
`crossterm`, `termion`, and `termwiz` can now be accessed as
`ratatui::{crossterm, termion, termwiz}` respectively. This makes it
possible to just add the Ratatui crate as a dependency and use the
backend of choice without having to add the backend crates as
dependencies.
To update existing code, replace all instances of `crossterm::` with
`ratatui::crossterm::`, `termion::` with `ratatui::termion::`, and
`termwiz::` with `ratatui::termwiz::`.

```text
his PR removes the items from the prelude that don't form a coherent
common vocabulary and adds the missing items that do.
Based on a comment at
<https://www.reddit.com/r/rust/comments/1cle18j/comment/l2uuuh7/>
```
BREAKING CHANGE:The following items have been removed from the prelude:
- `style::Styled` - this trait is useful for widgets that want to
support the Stylize trait, but it adds complexity as widgets have two
`style` methods and a `set_style` method.
- `symbols::Marker` - this item is used by code that needs to draw to
the `Canvas` widget, but it's not a common item that would be used by
most users of the library.
- `terminal::{CompletedFrame, TerminalOptions, Viewport}` - these items
are rarely used by code that needs to interact with the terminal, and
they're generally only ever used once in any app.
The following items have been added to the prelude:
- `layout::{Position, Size}` - these items are used by code that needs
to interact with the layout system. These are newer items that were
added in the last few releases, which should be used more liberally.

- [70df102](https://github.com/ratatui/ratatui/commit/70df102de0154cdfbd6508659cf6ed649f820bc8) _(bench)_ Improve benchmark consistency by @EdJoPaTo in [#1126](https://github.com/ratatui/ratatui/pull/1126)
```text
Codegen units are optimized on their own. Per default bench / release
have 16 codegen units. What ends up in a codeget unit is rather random
and can influence a benchmark result as a code change can move stuff
into a different codegen unit → prevent / allow LLVM optimizations
unrelated to the actual change.

````text
Since deserialize now uses `FromStr` to deserialize color, serializing
`Color` RGB values, as well as index values, would produce an output
that would no longer be able to be deserialized without causing an
error.
````
Color::Rgb will now be serialized as the hex representation of their
value.
For example, with serde_json, `Color::Rgb(255, 0, 255)` would be
serialized as `"#FF00FF"` rather than `{"Rgb": [255, 0, 255]}`.
Color::Indexed will now be serialized as just the string of the index.
For example, with serde_json, `Color::Indexed(10)` would be serialized
as `"10"` rather than `{"Indexed": 10}`.
Other color variants remain the same.
### Refactor
- [2cfe82a](https://github.com/ratatui/ratatui/commit/2cfe82a47eb34baa25f474db7be364de7b95374a) _(buffer)_ Deprecate assert_buffer_eq! in favor of assert_eq! by @EdJoPaTo in [#1007](https://github.com/ratatui/ratatui/pull/1007)
````text
- Simplify `assert_buffer_eq!` logic.
- Deprecate `assert_buffer_eq!`.
- Introduce `TestBackend::assert_buffer_lines`.
Also simplify many tests involving buffer comparisons.
For the deprecation, just use `assert_eq` instead of `assert_buffer_eq`:
```diff
-assert_buffer_eq!(actual, expected);
+assert_eq!(actual, expected);
```
---
I noticed `assert_buffer_eq!` creating no test coverage reports and
looked into this macro. First I simplified it. Then I noticed a bunch of
`assert_eq!(buffer, …)` and other indirect usages of this macro (like
`TestBackend::assert_buffer`).
The good thing here is that it's mainly used in tests so not many
changes to the library code.

We need to make sure to not change existing methods without a notice.
But at the same time this also finds public additions with mistakes
before they are even released which is what I would like to have.
This renames a method and deprecated the old name hinting to a new name.
Should this be mentioned somewhere, so it's added to the release notes?
It's not breaking because the old method is still there.

**Full Changelog**: <https://github.com/ratatui/ratatui/compare/v0.26.1...0.26.2>
## [0.26.1](https://github.com/ratatui/ratatui/releases/tag/v0.26.1) - 2024-02-12
This is a patch release that fixes bugs and adds enhancements, including new iterators, title options for blocks, and various rendering improvements. ✨
### Features
- [74a0511](https://github.com/ratatui/ratatui/commit/74a051147a4059990c31e08d96a8469d8220537b)
_(rect)_ Add Rect::positions iterator ([#928](https://github.com/ratatui/ratatui/issues/928))
````text
Useful for performing some action on all the cells in a particular area.
E.g.,
```rust
fn render(area: Rect, buf: &mut Buffer) {
for position in area.positions() {
buf.get_mut(position.x, position.y).set_symbol("x");
}
}
```

- [9182f47](https://github.com/ratatui/ratatui/commit/9182f47026d1630cb749163b6f8b8987474312ae)
_(uncategorized)_ Add Block::title_top and Block::title_top_bottom ([#940](https://github.com/ratatui/ratatui/issues/940))
````text
This adds the ability to add titles to the top and bottom of a block
without having to use the `Title` struct (which will be removed in a
future release - likely v0.28.0).
Fixes a subtle bug if the title was created from a right aligned Line
and was also right aligned. The title would be rendered one cell too far
to the right.
```rust
Block::bordered()
.title_top(Line::raw("A").left_aligned())
.title_top(Line::raw("B").centered())
.title_top(Line::raw("C").right_aligned())
.title_bottom(Line::raw("D").left_aligned())
.title_bottom(Line::raw("E").centered())
.title_bottom(Line::raw("F").right_aligned())
.render(buffer.area, &mut buffer);
// renders
"┌A─────B─────C┐",
"│ │",
"└D─────E─────F┘",
```
Addresses part of https://github.com/ratatui/ratatui/issues/738
````
### Bug Fixes
- [2202059](https://github.com/ratatui/ratatui/commit/220205925911ed4377358d2a28ffca9373f11bda)
_(block)_ Fix crash on empty right aligned title ([#933](https://github.com/ratatui/ratatui/issues/933))
````text
- Simplified implementation of the rendering for block.
- Introduces a subtle rendering change where centered titles that are
odd in length will now be rendered one character to the left compared
to before. This aligns with other places that we render centered text
and is a more consistent behavior. See
https://github.com/ratatui/ratatui/pull/807#discussion_r1455645954
for another example of this.

- [14c67fb](https://github.com/ratatui/ratatui/commit/14c67fbb52101d10b2d2e26898c408ab8dd3ec2d)
_(list)_ Highlight symbol when using a multi-bytes char ([#924](https://github.com/ratatui/ratatui/issues/924))
````text
ratatui v0.26.0 brought a regression in the List widget, in which the
highlight symbol width was incorrectly calculated - specifically when
the highlight symbol was a multi-char character, e.g. `▶`.

- [0dcdbea](https://github.com/ratatui/ratatui/commit/0dcdbea083aace6d531c0d505837e0911f400675)

````text
Renders the styled graphemes of the line instead of the contained spans.

_(uncategorized)_ Ensure that buffer::set_line sets the line style ([#926](https://github.com/ratatui/ratatui/issues/926))
````text
Fixes a regression in 0.26 where buffer::set_line was no longer setting
the style. This was due to the new style field on Line instead of being
stored only in the spans.
Also adds a configuration for just running unit tests to bacon.toml.

_(layout)_ Change `Flex::default()` ([#881](https://github.com/ratatui/ratatui/issues/881)) [**breaking**]
````text
This PR makes a number of simplifications to the layout and constraint
features that were added after v0.25.0.
For users upgrading from v0.25.0, the net effect of this PR (along with
the other PRs) is the following:
- New `Flex` modes have been added.
- `Flex::Start` (new default)
- `Flex::Center`
- `Flex::End`
- `Flex::SpaceAround`
- `Flex::SpaceBetween`
- `Flex::Legacy` (old default)
- `Min(v)` grows to allocate excess space in all `Flex` modes instead of
shrinking (except in `Flex::Legacy` where it retains old behavior).
- `Fill(1)` grows to allocate excess space, growing equally with
`Min(v)`.
---
The following contains a summary of the changes in this PR and the
motivation behind them.
**`Flex`**
- Removes `Flex::Stretch`
- Renames `Flex::StretchLast` to `Flex::Legacy`
**`Constraint`**
- Removes `Fixed`
- Makes `Min(v)` grow as much as possible everywhere (except
`Flex::Legacy` where it retains the old behavior)
- Makes `Min(v)` grow equally as `Fill(1)` while respecting `Min` lower
bounds. When `Fill` and `Min` are used together, they both fill excess
space equally.
Allowing `Min(v)` to grow still allows users to build the same layouts
as before with `Flex::Start` with no breaking changes to the behavior.
This PR also removes the unstable feature `SegmentSize`.
This is a breaking change to the behavior of constraints. If users want
old behavior, they can use `Flex::Legacy`.
```rust
Layout::vertical([Length(25), Length(25)]).flex(Flex::Legacy)
```
Users that have constraint that exceed the available space will probably
not see any difference or see an improvement in their layouts. Any
layout with `Min` will be identical in `Flex::Start` and `Flex::Legacy`
so any layout with `Min` will not be breaking.
Previously, `Table` used `EvenDistribution` internally by default, but
with that gone the default is now `Flex::Start`. This changes the
behavior of `Table` (for the better in most cases). The only way for
users to get exactly the same as the old behavior is to change their
constraints. I imagine most users will be happier out of the box with
the new Table default.

This is a somewhat arbitrary size for the layout cache based on adding
the columns and rows on my laptop's terminal (171+51 = 222) and doubling
it for good measure and then adding a bit more to make it a round
number. This gives enough entries to store a layout for every row and
every column, twice over, which should be enough for most apps. For
those that need more, the cache size can be set with
`Layout::init_cache()`.

* feat(layout): add a Rect::clamp() method
This ensures a rectangle does not end up outside an area. This is useful
when you want to be able to dynamically move a rectangle around, but

be moved around, but not outside the terminal window.
```rust
let window_area = Rect::new(state.x, state.y, 20, 20).clamp(area);
state.x = rect.x;
state.y = rect.y;

_(uncategorized)_ Add WidgetRef and StatefulWidgetRef traits ([#903](https://github.com/ratatui/ratatui/issues/903))
````text
The Widget trait consumes self, which makes it impossible to use in a
boxed context. Previously we implemented the Widget trait for &T, but
this was not enough to render a boxed widget. We now have a new trait
called `WidgetRef` that allows rendering a widget by reference. This
trait is useful when you want to store a reference to one or more
widgets and render them later. Additionally this makes it possible to
render boxed widgets where the type is not known at compile time (e.g.
in a composite layout with multiple panes of different types).
This change also adds a new trait called `StatefulWidgetRef` which is
the stateful equivalent of `WidgetRef`.
Both new traits are gated behind the `unstable-widget-ref` feature flag
as we may change the exact name / approach a little on this based on
further discussion.
Blanket implementation of `Widget` for `&W` where `W` implements
`WidgetRef` and `StatefulWidget` for `&W` where `W` implements
`StatefulWidgetRef` is provided. This allows you to render a widget by
reference and a stateful widget by reference.
A blanket implementation of `WidgetRef` for `Option<W>` where `W`
implements `WidgetRef` is provided. This makes it easier to render
child widgets that are optional without the boilerplate of unwrapping
the option. Previously several widgets implemented this manually. This
commits expands the pattern to apply to all widgets.
```rust
struct Parent {
child: Option<Child>,
}
impl WidgetRef for Parent {
fn render_ref(&self, area: Rect, buf: &mut Buffer) {
self.child.render_ref(area, buf);
}
}
```
```rust
let widgets: Vec<Box<dyn WidgetRef>> = vec![Box::new(Greeting), Box::new(Farewell)];
for widget in widgets {
widget.render_ref(buf.area, &mut buf);
}
assert_eq!(buf, Buffer::with_lines(["Hello Goodbye"]));
```

It allows users to interactive explore how the constraints behave with
respect to each other and compare that across flex modes. It allows
users to swap constraints out for other constraints, increment or
decrement the values, add and remove constraints, and add spacing
It is also a good example for how to structure a simple TUI with several
Ratatui code patterns that are useful for refactoring.

This PR introduces different priorities for each kind of constraint.
This PR also adds tests that specifies this behavior. This PR resolves a
number of broken tests.
Fixes https://github.com/ratatui/ratatui/issues/827
With this PR, the layout algorithm will do the following in order:
1. Ensure that all the segments are within the user provided area and
ensure that all segments and spacers are aligned next to each other
2. if a user provides a `layout.spacing`, it will enforce it.
3. ensure proportional elements are all proportional to each other
4. if a user provides a `Fixed(v)` constraint, it will enforce it.
5. `Min` / `Max` binding inequality constraints
6. `Length`
7. `Percentage`
8. `Ratio`
9. collapse `Min` or collapse `Max`
10. grow `Proportional` as much as possible
11. grow spacers as much as possible
This PR also returns the spacer areas as `Rects` to the user. Users can
then draw into the spacers as they see fit (thanks @joshka for the
idea). Here's a screenshot with the modified flex example:

````text
This PR adds `Color::from_hsl` that returns a valid `Color::Rgb`.
```rust
let color: Color = Color::from_hsl(360.0, 100.0, 100.0);

let color: Color = Color::from_hsl(0.0, 0.0, 0.0);
assert_eq!(color, Color::Rgb(0, 0, 0));
```
HSL stands for Hue (0-360 deg), Saturation (0-100%), and Lightness
(0-100%) and working with HSL the values can be more intuitive. For
example, if you want to make a red color more orange, you can change the
Hue closer toward yellow on the color wheel (i.e. increase the Hue).

This uses the new `spacing` feature of the `Layout` struct to allocate
columns spacing in the `Table` widget.
This changes the behavior of the table column layout in the following
ways:
1. Selection width is always allocated.

`HighlightSpacing::Never`
2. Column spacing is prioritized over other constraints
- if a user does not want column spacing, they should use
`Table::new(...).column_spacing(0)`

_(uncategorized)_ Add flex to layout ✨
```text
This PR adds a new way to space elements in a `Layout`.
Loosely based on
[flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/), this
PR adds a `Flex` enum with the following variants:
- Start
- Center
- End
- SpaceAround
- SpaceBetween
<img width="380" alt="image" src="https://github.com/ratatui/ratatui/assets/1813121/b744518c-eae7-4e35-bbc4-fe3c95193cde">
It also adds two more variants, to make this backward compatible and to
make it replace `SegmentSize`:
- StretchLast (default in the `Flex` enum, also behavior matches old
default `SegmentSize::LastTakesRemainder`)
- Stretch (behavior matches `SegmentSize::EvenDistribution`)
The `Start` variant from above matches `SegmentSize::None`.
This allows `Flex` to be a complete replacement for `SegmentSize`, hence
this PR also deprecates the `segment_size` constructor on `Layout`.
`SegmentSize` is still used in `Table` but under the hood `segment_size`
maps to `Flex` with all tests passing unchanged.
I also put together a simple example for `Flex` layouts so that I could
test it visually, shared below:

````text
* feat: accept Color and Modifier for all Styles
All style related methods now accept `S: Into<Style>` instead of
`Style`.
`Color` and `Modifier` implement `Into<Style>` so this is allows for
more ergonomic usage. E.g.:
```rust
Line::styled("hello", Style::new().red());
Line::styled("world", Style::new().bold());
// can now be simplified to
````
Line::styled("hello", Color::Red);
Line::styled("world", Modifier::BOLD);
`````
Fixes https://github.com/ratatui/ratatui/issues/694
BREAKING CHANGE:All style related methods now accept `S: Into<Style>`
instead of `Style`. This means that if you are already passing an
ambiguous type that implements `Into<Style>` you will need to remove
the `.into()` call.
`Block` style methods can no longer be called from a const context as
trait functions cannot (yet) be const.
* feat: add tuple conversions to Style
Adds conversions for various Color and Modifier combinations
* chore: add unit tests

```text
In https://github.com/ratatui/ratatui/pull/660 we introduced the
segment_size field to the Table struct. However, we forgot to update
the default() implementation to match the new() implementation. This
meant that the default() implementation picked up SegmentSize::default()
instead of SegmentSize::None.
Additionally the introduction of Table::default() in an earlier PR,
https://github.com/ratatui/ratatui/pull/339, was also missing the
default for the column_spacing field (1).
This commit fixes the default() implementation to match the new()
implementation of these two fields by implementing the Default trait
manually.
```
BREAKING CHANGE:The default() implementation of Table now sets the
column_spacing field to 1 and the segment_size field to
SegmentSize::None. This will affect the rendering of a small amount of
apps.

_(colors_rgb)_ Impl widget on mutable refs ([#865](https://github.com/ratatui/ratatui/issues/865))
```text
This commit refactors the colors_rgb example to implement the Widget
trait on mutable references to the app and its sub-widgets. This allows
the app to update its state while it is being rendered.
Additionally the main and run functions are refactored to be similar to
the other recent examples. This uses a pattern where the App struct has
a `run` method that takes a terminal as an argument, and the main
function is in control of initializing and restoring the terminal and
installing the error hooks.

It improves the UI of the layouts by
- thoughtful accessible color that represent priority in constraints
resolving
- using QUADRANT_OUTSIDE symbol set for block rendering
- adding a scrollbar
- panic handling
- refactoring for readability
to name a few. Here are some example gifs of the outcome:

Simplified a bunch of the logic in the demo2 example
- Moved destroy mode to its own file.
- Moved error handling to its own file.
- Removed AppContext
- Implemented Widget for &App. The app state is small enough that it
doesn't matter here and we could just copy or clone the app state on
every frame, but for larger apps this can be a significant performance
improvement.
- Made the tabs stateful
- Made the term module just a collection of functions rather than a
struct.
- Changed to use color_eyre for error handling.
- Changed keyboard shortcuts and rearranged the bottom bar.
- Use strum for the tabs enum.

## [0.25.0](https://github.com/ratatui/ratatui/releases/tag/v0.25.0) - 2023-12-18
We are thrilled to announce the new version of `ratatui` - a Rust library that's all about cooking up TUIs 🐭
In this version, we made improvements on widgets such as List, Table and Layout and changed some of the defaults for a better user experience.
Also, we renewed our website and updated our documentation/tutorials to get started with `ratatui`: <https://ratatui.rs> 🚀
✨ **Release highlights**: <https://ratatui.rs/highlights/v025/>
⚠️ List of breaking changes can be found [here](https://github.com/ratatui/ratatui/blob/main/BREAKING-CHANGES.md).
💖 We also enabled GitHub Sponsors for our organization, consider sponsoring us if you like `ratatui`: <https://github.com/sponsors/ratatui>
### Features
- [aef4956](https://github.com/ratatui/ratatui/commit/aef495604c52e563fbacfb1a6e730cd441a99129)
_(list)_ `List::new` now accepts `IntoIterator<Item = Into<ListItem>>` ([#672](https://github.com/ratatui/ratatui/issues/672)) [**breaking**]
````text
This allows to build list like
```
List::new(["Item 1", "Item 2"])
```
````
- [8bfd666](https://github.com/ratatui/ratatui/commit/8bfd6661e251b6943f74bda626e4708b2e9f4b51)
_(paragraph)_ Add `line_count` and `line_width` unstable helper methods
````text
This is an unstable feature that may be removed in the future
````
- [1229b96](https://github.com/ratatui/ratatui/commit/1229b96e428df880a951ef57f53ca73e74ef1ea2)
_(rect)_ Add `offset` method ([#533](https://github.com/ratatui/ratatui/issues/533))
````text
The offset method creates a new Rect that is moved by the amount
specified in the x and y direction. These values can be positive or
negative. This is useful for manual layout tasks.
```rust
let rect = area.offset(Offset { x: 10, y -10 });
```
````
- [edacaf7](https://github.com/ratatui/ratatui/commit/edacaf7ff4e4b14702f6361af5a6da713b7dc564)
_(buffer)_ Deprecate `Cell::symbol` field ([#624](https://github.com/ratatui/ratatui/issues/624))
````text
The Cell::symbol field is now accessible via a getter method (`symbol()`). This will
allow us to make future changes to the Cell internals such as replacing `String` with
`compact_str`.
````
- [6b2efd0](https://github.com/ratatui/ratatui/commit/6b2efd0f6c3bf56dc06bbf042db40c0c66de577e)
_(layout)_ Accept IntoIterator for constraints ([#663](https://github.com/ratatui/ratatui/issues/663))
````text
Layout and Table now accept IntoIterator for constraints with an Item
that is AsRef<Constraint>. This allows pretty much any collection of
constraints to be passed to the layout functions including arrays,
vectors, slices, and iterators (without having to call collect() on
them).
````
- [753e246](https://github.com/ratatui/ratatui/commit/753e246531e1e9e2ea558911f8d03e738901d85f)
_(layout)_ Allow configuring layout fill ([#633](https://github.com/ratatui/ratatui/issues/633))
````text
The layout split will generally fill the remaining area when `split()`
is called. This change allows the caller to configure how any extra
space is allocated to the `Rect`s. This is useful for cases where the
caller wants to have a fixed size for one of the `Rect`s, and have the
other `Rect`s fill the remaining space.
For now, the method and enum are marked as unstable because the exact
name is still being bikeshedded. To enable this functionality, add the
`unstable-segment-size` feature flag in your `Cargo.toml`.
To configure the layout to fill the remaining space evenly, use
`Layout::segment_size(SegmentSize::EvenDistribution)`. The default
behavior is `SegmentSize::LastTakesRemainder`, which gives the last
segment the remaining space. `SegmentSize::None` will disable this
behavior. See the docs for `Layout::segment_size()` and
`layout::SegmentSize` for more information.

- [1e2f0be](https://github.com/ratatui/ratatui/commit/1e2f0be75ac3fb3d6500c1de291bd49972b808e4)
_(layout)_ Add parameters to Layout::new() ([#557](https://github.com/ratatui/ratatui/issues/557)) [**breaking**]
````text
Adds a convenience function to create a layout with a direction and a
list of constraints which are the most common parameters that would be
generally configured using the builder pattern. The constraints can be
passed in as any iterator of constraints.
```rust
let layout = Layout::new(Direction::Horizontal, [
Constraint::Percentage(50),
Constraint::Percentage(50),
]);
```

````text
The `List` widget now respects the alignment of `Line`s and renders them as expected.

- [e49385b](https://github.com/ratatui/ratatui/commit/e49385b78c8e01fe6381b19d15137346bc6eb8a1)
_(table)_ Add a Table::segment_size method ([#660](https://github.com/ratatui/ratatui/issues/660))
````text
It controls how to distribute extra space to an underconstrained table.
The default, legacy behavior is to leave the extra space unused. The
new options are LastTakesRemainder which gets all space to the rightmost
column that can used it, and EvenDistribution which divides it amongst
all columns.

- [d19b266](https://github.com/ratatui/ratatui/commit/d19b266e0eabdb0fb00660439a1818239c94024b)
_(uncategorized)_ Add Constraint helpers (e.g. from_lengths) ([#641](https://github.com/ratatui/ratatui/issues/641))
````text
Adds helper methods that convert from iterators of u16 values to the
specific Constraint type. This makes it easy to create constraints like:
```rust
// a fixed layout
let constraints = Constraint::from_lengths([10, 20, 10]);
// a centered layout
let constraints = Constraint::from_ratios([(1, 4), (1, 2), (1, 4)]);
let constraints = Constraint::from_percentages([25, 50, 25]);
// a centered layout with a minimum size
let constraints = Constraint::from_mins([0, 100, 0]);
// a sidebar / main layout with maximum sizes
let constraints = Constraint::from_maxes([30, 200]);
```

_(block)_ Make `inner` aware of title positions ([#657](https://github.com/ratatui/ratatui/issues/657))
````text
Previously, when computing the inner rendering area of a block, all
titles were assumed to be positioned at the top, which caused the
height of the inner area to be miscalculated.

_(table)_ Widths() now accepts AsRef<[Constraint]> ([#628](https://github.com/ratatui/ratatui/issues/628))
````text
This allows passing an array, slice or Vec of constraints, which is more
ergonomic than requiring this to always be a slice.
The following calls now all succeed:
```rust
Table::new(rows).widths([Constraint::Length(5), Constraint::Length(5)]);
Table::new(rows).widths(&[Constraint::Length(5), Constraint::Length(5)]);
// widths could also be computed at runtime
let widths = vec![Constraint::Length(5), Constraint::Length(5)];
Table::new(rows).widths(widths.clone());
Table::new(rows).widths(&widths);
```

_(tabs)_ Set the default highlight_style ([#635](https://github.com/ratatui/ratatui/issues/635)) [**breaking**]
````text
Previously the default highlight_style was set to `Style::default()`,
which meant that the highlight style was the same as the normal style.
This change sets the default highlight_style to reversed text.

_(layout)_ To natural reading order ([#681](https://github.com/ratatui/ratatui/issues/681))
````text
Structs and enums at the top of the file helps show the interaction
between the types without having to find each type in between longer
impl sections.
Also moved the try_split function into the Layout impl as an associated
function and inlined the `layout::split()` which just called try_split.
This makes the code a bit more contained.

````text
- Refactor the `table` module for better top to bottom readability by
putting types first and arranging them in a logical order (Table, Row,

## [0.24.0](https://github.com/ratatui/ratatui/releases/tag/v0.24.0) - 2023-10-23
We are excited to announce the new version of `ratatui` - a Rust library that's all about cooking up TUIs 🐭
In this version, we've introduced features like window size API, enhanced chart rendering, and more.
The list of \*breaking changes\* can be found [here](https://github.com/ratatui/ratatui/blob/main/BREAKING-CHANGES.md) ⚠️.
Also, we created various tutorials and walkthroughs in [Ratatui Book](https://github.com/ratatui/ratatui-book) which is available at <https://ratatui.rs> 🚀
✨ **Release highlights**: <https://ratatui.rs/highlights/v024>
### Features

_(backend)_ Implement common traits for `WindowSize` ([#586](https://github.com/ratatui/ratatui/issues/586))
- [d077903](https://github.com/ratatui/ratatui/commit/d0779034e741834aac36b5b7a87c54bd8c50b7f2)
_(backend)_ Backend provides window_size, add Size struct ([#276](https://github.com/ratatui/ratatui/issues/276))
```text
For image (sixel, iTerm2, Kitty...) support that handles graphics in
terms of `Rect` so that the image area can be included in layouts.
For example: an image is loaded with a known pixel-size, and drawn, but
the image protocol has no mechanism of knowing the actual cell/character
area that been drawn on. It is then impossible to skip overdrawing the
area.
Returning the window size in pixel-width / pixel-height, together with
columns / rows, it can be possible to account the pixel size of each cell
/ character, and then known the `Rect` of a given image, and also resize
the image so that it fits exactly in a `Rect`.
Crossterm and termwiz also both return both sizes from one syscall,
while termion does two.
Add a `Size` struct for the cases where a `Rect`'s `x`/`y` is unused
(always zero).
`Size` is not "clipped" for `area < u16::max_value()` like `Rect`. This
is why there are `From` implementations between the two.

_(barchart)_ Render charts smaller than 3 lines ([#532](https://github.com/ratatui/ratatui/issues/532))
```text
The bar values are not shown if the value width is equal the bar width
and the bar is height is less than one line
Add an internal structure `LabelInfo` which stores the reserved height
for the labels (0, 1 or 2) and also whether the labels will be shown.
Fixes ratatui#513

_(block)_ Allow custom symbols for borders ([#529](https://github.com/ratatui/ratatui/issues/529)) [**breaking**]
````text
Adds a new `Block::border_set` method that allows the user to specify
the symbols used for the border.
Added two new border types: `BorderType::QuadrantOutside` and
`BorderType::QuadrantInside`. These are used to draw borders using the
unicode quadrant characters (which look like half block "pixels").

_(canvas)_ Implement half block marker ([#550](https://github.com/ratatui/ratatui/issues/550))
```text
* feat(canvas): implement half block marker
A useful technique for the terminal is to use half blocks to draw a grid
of "pixels" on the screen. Because we can set two colors per cell, and
because terminal cells are about twice as tall as they are wide, we can
draw a grid of half blocks that looks like a grid of square pixels.
This commit adds a new `HalfBlock` marker that can be used in the Canvas
widget and the associated HalfBlockGrid.
Also updated demo2 to use the new marker as it looks much nicer.
Adds docs for many of the methods and structs on canvas.
Changes the grid resolution method to return the pixel count
rather than the index of the last pixel.
This is an internal detail with no user impact.

_(frame)_ Remove generic Backend parameter ([#530](https://github.com/ratatui/ratatui/issues/530)) [**breaking**]
````text
This change simplifies UI code that uses the Frame type. E.g.:
```rust
fn draw<B: Backend>(frame: &mut Frame<B>) {
// ...
}
```
Frame was generic over Backend because it stored a reference to the
terminal in the field. Instead it now directly stores the viewport area
and current buffer. These are provided at creation time and are valid
for the duration of the frame.
BREAKING CHANGE: Frame is no longer generic over Backend. Code that
accepted a Frame<Backend> will now need to accept a Frame.

```text
- add `Rect::is_empty()` that checks whether either height or width == 0
- refactored `Rect` into layout/rect.rs from layout.rs. No public API change as
the module is private and the type is re-exported under the `layout` module.

- [638d596](https://github.com/ratatui/ratatui/commit/638d596a3b7aec723a2354cf0e261b207ac412f8)
_(layout)_ Use LruCache for layout cache ([#487](https://github.com/ratatui/ratatui/issues/487))
```text
The layout cache now uses a LruCache with default size set to 16 entries.
Previously the cache was backed by a HashMap, and was able to grow
without bounds as a new entry was added for every new combination of
layout parameters.
- Added a new method (`layout::init_cache(usize)`) that allows the cache
size to be changed if necessary. This will only have an effect if it is called
prior to any calls to `layout::split()` as the cache is wrapped in a `OnceLock`

_(backend)_ Add feature flag for underline-color ([#570](https://github.com/ratatui/ratatui/issues/570))
````text
Windows 7 doesn't support the underline color attribute, so we need to
make it optional. This commit adds a feature flag for the underline
color attribute - it is enabled by default, but can be disabled by
passing `--no-default-features` to cargo.
We could specically check for Windows 7 and disable the feature flag
automatically, but I think it's better for this check to be done by the
crossterm crate, since it's the one that actually knows about the
underlying terminal.
To disable the feature flag in an application that supports Windows 7,
add the following to your Cargo.toml:
```toml
ratatui = { version = "0.24.0", default-features = false, features = ["crossterm"] }
```

_(stylize)_ Add Stylize impl for String ([#466](https://github.com/ratatui/ratatui/issues/466)) [**breaking**]
```text
Although the `Stylize` trait is already implemented for `&str` which
extends to `String`, it is not implemented for `String` itself. This
commit adds an impl of Stylize that returns a Span<'static> for `String`
so that code can call Stylize methods on temporary `String`s.
E.g. the following now compiles instead of failing with a compile error
about referencing a temporary value:
let s = format!("hello {name}!", "world").red();
BREAKING CHANGE: This may break some code that expects to call Stylize
methods on `String` values and then use the String value later. This
will now fail to compile because the String is consumed by set_style
instead of a slice being created and consumed.
This can be fixed by cloning the `String`. E.g.:
let s = String::from("hello world");
let line = Line::from(vec![s.red(), s.green()]); // fails to compile
let line = Line::from(vec![s.clone().red(), s.green()]); // works

_(barchart)_ Simplify internal implementation ([#544](https://github.com/ratatui/ratatui/issues/544))
```text
Replace `remove_invisible_groups_and_bars` with `group_ticks`
`group_ticks` calculates the visible bar length in ticks. (A cell contains 8 ticks).
It is used for 2 purposes:
1. to get the bar length in ticks for rendering
2. since it delivers only the values of the visible bars, If we zip these values
with the groups and bars, then we will filter out the invisible groups and bars

## [v0.23.0](https://github.com/ratatui/ratatui/releases/tag/v0.23.0) - 2023-08-28
We are thrilled to release the new version of `ratatui` 🐭, the official successor[\*](https://github.com/fdehau/tui-rs/commit/335f5a4563342f9a4ee19e2462059e1159dcbf25) of [`tui-rs`](https://github.com/fdehau/tui-rs).
In this version, we improved the existing widgets such as `Barchart` and `Scrollbar`. We also made improvmements in the testing/internal APIs to provide a smoother testing/development experience. Additionally, we have addressed various bugs and implemented enhancements.
Here is a blog post that highlights the new features and breaking changes along with a retrospective about the project: [https://blog.orhun.dev/ratatui-0-23-0](https://blog.orhun.dev/ratatui-0-23-0)
### Features
- _(barchart)_ Add direction attribute. (horizontal bars support) ([#325](https://github.com/ratatui/ratatui/issues/325))
([0dca6a6](https://github.com/ratatui/ratatui/commit/0dca6a689a7af640c5de8f7c87c2f1e03f0adf25))
````text
* feat(barchart): Add direction attribute
Enable rendering the bars horizontally. In some cases this allow us to
make more efficient use of the available space.

- _(cell)_ Add voluntary skipping capability for sixel ([#215](https://github.com/ratatui/ratatui/issues/215))
([e4bcf78](https://github.com/ratatui/ratatui/commit/e4bcf78afabe6b06970c51b4284246e345002cf5))
````text
> Sixel is a bitmap graphics format supported by terminals.
> "Sixel mode" is entered by sending the sequence ESC+Pq.
> The "String Terminator" sequence ESC+\ exits the mode.
The graphics are then rendered with the top left positioned at the
cursor position.
It is actually possible to render sixels in ratatui with just
`buf.get_mut(x, y).set_symbol("^[Pq ... ^[\")`. But any buffer covering
the "image area" will overwrite the graphics. This is most likely the same
buffer, even though it consists of empty characters `' '`, except for
the top-left character that starts the sequence.
Thus, either the buffer or cells must be specialized to avoid drawing
over the graphics. This patch specializes the `Cell` with a
`set_skip(bool)` method, based on James' patch:
https://github.com/TurtleTheSeaHobo/tui-rs/tree/sixel-support
I unsuccessfully tried specializing the `Buffer`, but as far as I can tell
buffers get merged all the way "up" and thus skipping must be set on the
Cells. Otherwise some kind of "skipping area" state would be required,
which I think is too complicated.
Having access to the buffer now it is possible to skip all cells but the
first one which can then `set_symbol(sixel)`. It is up to the user to
deal with the graphics size and buffer area size. It is possible to get
the terminal's font size in pixels with a syscall.
An image widget for ratatui that uses this `skip` flag is available at
https://github.com/benjajaja/ratatu-image.

- _(layout)_ Don't leave gaps between chunks ([#408](https://github.com/ratatui/ratatui/issues/408))
([56455e0](https://github.com/ratatui/ratatui/commit/56455e0fee57616f87ea43872fb7d5d9bb14aff5))
````text
Previously the layout used the floor of the calculated start and width
as the value to use for the split Rects. This resulted in gaps between
the split rects.
This change modifies the layout to round to the nearest column instead
of taking the floor of the start and width. This results in the start
and end of each rect being rounded the same way and being strictly
adjacent without gaps.
Because there is a required constraint that ensures that the last end is
equal to the area end, there is no longer the need to fixup the last
item width when the fill (as e.g. width = x.99 now rounds to x+1 not x).
The colors example has been updated to use Ratio(1, 8) instead of
Percentage(13), as this now renders without gaps for all possible sizes,

````text
This commit adds a readme to the examples directory with gifs of each
example. This should make it easier to see what each example does
without having to run it.
I modified the examples to fit better in the gifs. Mostly this was just
removing the margins, but for the block example I cleaned up the code a
bit to make it more readable and changed it so the background bug is not
triggered.
For the table example, the combination of Min, Length, and Percent
constraints was causing the table to panic when the terminal was too
small. I changed the example to use the Max constraint instead of the
Length constraint.
The layout example now shows information about how the layout is
constrained on each block (which is now a paragraph with a block).

## v0.20.0 - 2023-03-19

## v0.19.0 - 2022-08-14
### Features
- Bump `crossterm` to `0.25`
## v0.18.0 - 2022-04-24
### Features
- Update `crossterm` to `0.23`
## v0.17.0 - 2022-01-22
### Features
- Add option to `widgets::List` to repeat the highlight symbol for each line of multi-line items (#533).
- Add option to control the alignment of `Axis` labels in the `Chart` widget (#568).
### Breaking changes
- The minimum supported rust version is now `1.56.1`.
#### New default backend and consolidated backend options (#553)
- `crossterm` is now the default backend.
If you are already using the `crossterm` backend, you can simplify your dependency specification in `Cargo.toml`:
```diff
- tui = { version = "0.16", default-features = false, features = ["crossterm"] }
+ tui = "0.17"
```
If you are using the `termion` backend, your `Cargo` is now a bit more verbose:
```diff
- tui = "0.16"
+ tui = { version = "0.17", default-features = false, features = ["termion"] }
```
`crossterm` has also been bumped to version `0.22`.
Because of their apparent low usage, `curses` and `rustbox` backends have been removed.
If you are using one of them, you can import their last implementation in your own project:
- [curses](https://github.com/fdehau/tui-rs/blob/v0.16.0/src/backend/curses.rs)
- [rustbox](https://github.com/fdehau/tui-rs/blob/v0.16.0/src/backend/rustbox.rs)
#### Canvas labels (#543)
- Labels of the `Canvas` widget are now `text::Spans`.
The signature of `widgets::canvas::Context::print` has thus been updated:
```diff
- ctx.print(x, y, "Some text", Color::Yellow);
+ ctx.print(x, y, Span::styled("Some text", Style::default().fg(Color::Yellow)))
```
## v0.16.0 - 2021-08-01
### Features
- Update `crossterm` to `0.20`.
- Add `From<Cow<str>>` implementation for `text::Text` (#471).
- Add option to right or center align the title of a `widgets::Block` (#462).

#### New API for the Table widget
The `Table` widget got a lot of improvements that should make it easier to work with:
- It should not longer panic when rendered on small areas.
- `Row`s are now a collection of `Cell`s, themselves wrapping a `Text`. This means you can style
the entire `Table`, an entire `Row`, an entire `Cell` and rely on the styling capabilities of
`Text` to get full control over the look of your `Table`.
- `Row`s can have multiple lines.
- The header is now optional and is just another `Row` always visible at the top.
- `Row`s can have a bottom margin.
- The header alignment is no longer off when an item is selected.
Taking the example of the code in `examples/demo/ui.rs`, this is what you may have to change:
```diff
let failure_style = Style::default()
.fg(Color::Red)
.add_modifier(Modifier::RAPID_BLINK | Modifier::CROSSED_OUT);
- let header = ["Server", "Location", "Status"];
let rows = app.servers.iter().map(|s| {
let style = if s.status == "Up" {
up_style
} else {
failure_style
};
- Row::StyledData(vec![s.name, s.location, s.status].into_iter(), style)
+ Row::new(vec![s.name, s.location, s.status]).style(style)
});
- let table = Table::new(header.iter(), rows)
+ let table = Table::new(rows)
+ .header(
+ Row::new(vec!["Server", "Location", "Status"])
+ .style(Style::default().fg(Color::Yellow))
+ .bottom_margin(1),
+ )
.block(Block::default().title("Servers").borders(Borders::ALL))
- .header_style(Style::default().fg(Color::Yellow))
.widths(&[
Constraint::Length(15),
Constraint::Length(15),
```
Here, we had to:
- Change the way we construct [`Row`](https://docs.rs/tui/*/tui/widgets/struct.Row.html) which is no
longer an `enum` but a `struct`. It accepts anything that can be converted to an iterator of things
that can be converted to a [`Cell`](https://docs.rs/tui/*/tui/widgets/struct.Cell.html)
- The header is no longer a required parameter so we use
[`Table::header`](https://docs.rs/tui/*/tui/widgets/struct.Table.html#method.header) to set it.
`Table::header_style` has been removed since the style can be directly set using
[`Row::style`](https://docs.rs/tui/*/tui/widgets/struct.Row.html#method.style). In addition, we want
to preserve the old margin between the header and the rest of the rows so we add a bottom margin to
the header using
[`Row::bottom_margin`](https://docs.rs/tui/*/tui/widgets/struct.Row.html#method.bottom_margin).
You may want to look at the documentation of the different types to get a better understanding:
- [`Table`](https://docs.rs/tui/*/tui/widgets/struct.Table.html)
- [`Row`](https://docs.rs/tui/*/tui/widgets/struct.Row.html)
- [`Cell`](https://docs.rs/tui/*/tui/widgets/struct.Cell.html)
### Fixes
- Fix handling of Non Breaking Space (NBSP) in wrapped text in `Paragraph` widget.
### Features
- Add `Style::reset` to create a `Style` resetting all styling properties when applied.
- Add an option to render the `Gauge` widget with unicode blocks.
- Manage common project tasks with `cargo-make` rather than `make` for easier on-boarding.
## v0.13.0 - 2020-11-14
### Features
- Add `LineGauge` widget which is a more compact variant of the existing `Gauge`.
- Bump `crossterm` to 0.18
### Fixes
- Take into account the borders of the `Table` widget when the widths of columns is controlled by
`Percentage` and `Ratio` constraints.
## v0.12.0 - 2020-09-27
### Features
- Make it easier to work with string with multiple lines in `Text` (#361).
### Fixes
- Fix a style leak in `Graph` so components drawn on top of the plotted data (i.e legend and axis
titles) are not affected by the style of the `Dataset`s (#388).
- Make sure `BarChart` shows bars with the max height only when the plotted data is actually equal
to the max (#383).
## v0.11.0 - 2020-09-20
### Features
- Add the dot character as a new type of canvas marker (#350).
- Support more style modifiers on Windows (#368).
### Fixes
- Clearing the terminal through `Terminal::clear` will cause the whole UI to be redrawn (#380).
- Fix incorrect output when the first diff to draw is on the second cell of the terminal (#347).
## v0.10.0 - 2020-07-17
### Breaking changes
#### Easier cursor management
A new method has been added to `Frame` called `set_cursor`. It lets you specify where the cursor
should be placed after the draw call. Furthermore like any other widgets, if you do not set a cursor
position during a draw call, the cursor is automatically hidden.
For example:
```rust
fn draw_input(f: &mut Frame, app: &App) {
if app.editing {
let input_width = app.input.width() as u16;
// The cursor will be placed just after the last character of the input
f.set_cursor((input_width + 1, 0));
} else {
// We are no longer editing, the cursor does not have to be shown, set_cursor is not called and
// thus automatically hidden.
}
}
```
In order to make this possible, the draw closure takes in input `&mut Frame` instead of `mut Frame`.
#### Advanced text styling
It has been reported several times that the text styling capabilities were somewhat limited in many
places of the crate. To solve the issue, this release includes a new set of text primitives that are
now used by a majority of widgets to provide flexible text styling.
`Text` is replaced by the following types:
- `Span`: a string with a unique style.
- `Spans`: a string with multiple styles.
- `Text`: a multi-lines string with multiple styles.
However, you do not always need this complexity so the crate provides `From` implementations to
let you use simple strings as a default and switch to the previous primitives when you need
additional styling capabilities.
For example, the title of a `Block` can be set in the following ways:
```rust
// A title with no styling
Block::default().title("My title");
// A yellow title
Block::default().title(Span::styled("My title", Style::default().fg(Color::Yellow)));
// A title where "My" is bold and "title" is a simple string
Block::default().title(vec![
Span::styled("My", Style::default().add_modifier(Modifier::BOLD)),
Span::from("title")
]);
```
- `Buffer::set_spans` and `Buffer::set_span` were added.
- `Paragraph::new` expects an input that can be converted to a `Text`.
- `Block::title_style` is deprecated.
- `Block::title` expects a `Spans`.
- `Tabs` expects a list of `Spans`.
- `Gauge` custom label is now a `Span`.
- `Axis` title and labels are `Spans` (as a consequence `Chart` no longer has generic bounds).
#### Incremental styling
Previously `Style` was used to represent an exhaustive set of style rules to be applied to an UI
element. It implied that whenever you wanted to change even only one property you had to provide the
complete style. For example, if you had a `Block` where you wanted to have a green background and
a title in bold, you had to do the following:
```rust
let style = Style::default().bg(Color::Green);
Block::default()
.style(style)
.title("My title")
// Here we reused the style otherwise the background color would have been reset
.title_style(style.modifier(Modifier::BOLD));
```
In this new release, you may now write this as:
```rust
Block::default()
.style(Style::default().bg(Color::Green))
// The style is not overridden anymore, we simply add new style rule for the title.
.title(Span::styled("My title", Style::default().add_modifier(Modifier::BOLD)))
```
In addition, the crate now provides a method `patch` to combine two styles into a new set of style
rules:
```rust
let style = Style::default().modifier(Modifier::BOLD);
let style = style.patch(Style::default().add_modifier(Modifier::ITALIC));
// style.modifier == Modifier::BOLD | Modifier::ITALIC, the modifier has been enriched not overridden
```
- `Style::modifier` has been removed in favor of `Style::add_modifier` and `Style::remove_modifier`.
- `Buffer::set_style` has been added. `Buffer::set_background` is deprecated.
- `BarChart::style` no longer set the style of the bars. Use `BarChart::bar_style` in replacement.
- `Gauge::style` no longer set the style of the gauge. Use `Gauge::gauge_style` in replacement.
#### List with item on multiple lines
The `List` widget has been refactored once again to support items with variable heights and complex
styling.
- `List::new` expects an input that can be converted to a `Vec<ListItem>` where `ListItem` is a
wrapper around the item content to provide additional styling capabilities. `ListItem` contains a
`Text`.
- `List::items` has been removed.
```rust
// Before
let items = vec![
"Item1",
"Item2",
"Item3"
];
List::default().items(items.iters());
// After
let items = vec![
ListItem::new("Item1"),
ListItem::new("Item2"),
ListItem::new("Item3"),
];
List::new(items);
```
See the examples for more advanced usages.
#### More wrapping options
`Paragraph::wrap` expects `Wrap` instead of `bool` to let users decided whether they want to trim
whitespaces when the text is wrapped.
```rust
// before
Paragraph::new(text).wrap(true)
// after
Paragraph::new(text).wrap(Wrap { trim: true }) // to have the same behavior
Paragraph::new(text).wrap(Wrap { trim: false }) // to use the new behavior
```
#### Horizontal scrolling in paragraph
You can now scroll horizontally in `Paragraph`. The argument of `Paragraph::scroll` has thus be
changed from `u16` to `(u16, u16)`.
### Features
#### Serialization of style
You can now serialize and de-serialize `Style` using the optional `serde` feature.
## v0.9.5 - 2020-05-21
### Bug Fixes
- Fix out of bounds panic in `widgets::Tabs` when the widget is rendered on
small areas.
## v0.9.4 - 2020-05-12
### Bug Fixes
- Ignore zero-width graphemes in `Buffer::set_stringn`.
## v0.9.3 - 2020-05-11
### Bug Fixes
- Fix usize overflows in `widgets::Chart` when a dataset is empty.
## v0.9.2 - 2020-05-10
### Bug Fixes
- Fix usize overflows in `widgets::canvas::Line` drawing algorithm.
## v0.9.1 - 2020-04-16
### Bug Fixes
- The `List` widget now takes into account the width of the `highlight_symbol`
when calculating the total width of its items. It prevents items to overflow
outside of the widget area.
## v0.9.0 - 2020-04-14
### Features
- Introduce stateful widgets, i.e widgets that can take advantage of keeping
some state around between two draw calls (#210 goes a bit more into the
details).
- Allow a `Table` row to be selected.
```rust
// State initialization
let mut state = TableState::default();
// In the terminal.draw closure
let header = ["Col1", "Col2", "Col"];
let rows = [
Row::Data(["Row11", "Row12", "Row13"].into_iter())
];
let table = Table::new(header.into_iter(), rows.into_iter());
f.render_stateful_widget(table, area, &mut state);
// In response to some event:
state.select(Some(1));
```
- Add a way to choose the type of border used to draw a block. You can now
choose from plain, rounded, double and thick lines.
- Add a `graph_type` property on the `Dataset` of a `Chart` widget. By
default it will be `Scatter` where the points are drawn as is. An other
option is `Line` where a line will be draw between each consecutive points
of the dataset.
- Style methods are now const, allowing you to initialize const `Style`
objects.
- Improve control over whether the legend in the `Chart` widget is shown or
not. You can now set custom constraints using
`Chart::hidden_legend_constraints`.
- Add `Table::header_gap` to add some space between the header and the first
row.
- Remove `log` from the dependencies
- Add a way to use a restricted set of unicode symbols in several widgets to
improve portability in exchange of a degraded output. (see `BarChart::bar_set`,
`Sparkline::bar_set` and `Canvas::marker`). You can check how the
`--enhanced-graphics` flag is used in the demos.
### Breaking Changes
- `Widget::render` has been deleted. You should now use `Frame::render_widget`
to render a widget on the corresponding `Frame`. This makes the `Widget`
implementation totally decoupled from the `Frame`.
```rust
// Before
Block::default().render(&mut f, size);
// After
let block = Block::default();
f.render_widget(block, size);
```
- `Widget::draw` has been renamed to `Widget::render` and the signature has
been updated to reflect that widgets are consumable objects. Thus the method
takes `self` instead of `&mut self`.
```rust
// Before
impl Widget for MyWidget {
fn draw(&mut self, area: Rect, buf: &mut Buffer) {
}
}
/// After
impl Widget for MyWidget {
fn render(self, arera: Rect, buf: &mut Buffer) {
}
}
```
- `Widget::background` has been replaced by `Buffer::set_background`
```rust
// Before
impl Widget for MyWidget {
fn render(self, arera: Rect, buf: &mut Buffer) {
self.background(area, buf, self.style.bg);
}
}
// After
impl Widget for MyWidget {
fn render(self, arera: Rect, buf: &mut Buffer) {
buf.set_background(area, self.style.bg);
}
}
```
- Update the `Shape` trait for objects that can be draw on a `Canvas` widgets.
Instead of returning an iterator over its points, a `Shape` is given a
`Painter` object that provides a `paint` as well as a `get_point` method. This
gives the `Shape` more information about the surface it will be drawn to. In
particular, this change allows the `Line` shape to use a more precise and
efficient drawing algorithm (Bresenham's line algorithm).
- `SelectableList` has been deleted. You can now take advantage of the
associated `ListState` of the `List` widget to select an item.
```rust
// Before
List::new(&["Item1", "Item2", "Item3"])
.select(Some(1))
.render(&mut f, area);
// After
// State initialization
let mut state = ListState::default();
// In the terminal.draw closure
let list = List::new(&["Item1", "Item2", "Item3"]);
f.render_stateful_widget(list, area, &mut state);
// In response to some events
state.select(Some(1));
```
- `widgets::Marker` has been moved to `symbols::Marker`
## v0.8.0 - 2019-12-15
### Breaking Changes
- Bump crossterm to 0.14.
- Add cross symbol to the symbols list.
### Bug Fixes
- Use the value of `title_style` to style the title of `Axis`.
## v0.7.0 - 2019-11-29
### Breaking Changes
- Use `Constraint` instead of integers to specify the widths of the `Table`
widget's columns. This will allow more responsive tables.
```rust
Table::new(header, row)
.widths(&[15, 15, 10])
.render(f, chunk);
```
becomes:
```rust
Table::new(header, row)
.widths(&[
Constraint::Length(15),
Constraint::Length(15),
Constraint::Length(10),
])
.render(f, chunk);
```
- Bump crossterm to 0.13.
- Use Github Actions for CI (Travis and Azure Pipelines integrations have been deleted).
### Features
- Add support for horizontal and vertical margins in `Layout`.
## v0.6.2 - 2019-07-16
### Features
- `Text` implements PartialEq
### Bug Fixes
- Avoid overflow errors in canvas
## v0.6.1 - 2019-06-16
### Bug Fixes
- Avoid a division by zero when all values in a barchart are equal to 0.
- Fix the inverted cursor position in the curses backend.
- Ensure that the correct terminal size is returned when using the crossterm
backend.
- Avoid highlighting the separator after the selected item in the Tabs widget.
## v0.6.0 - 2019-05-18
### Breaking Changes
- Update crossterm backend
## v0.5.1 - 2019-04-14
### Bug Fixes
- Fix a panic in the Sparkline widget
## v0.5.0 - 2019-03-10
### Features
- Add a new curses backend (with Windows support thanks to `pancurses`).
- Add `Backend::get_cursor` and `Backend::set_cursor` methods to query and
set the position of the cursor.
- Add more constructors to the `Crossterm` backend.
- Add a demo for all backends using a shared UI and application state.
- Add `Ratio` as a new variant of layout `Constraint`. It can be used to define
exact ratios constraints.
### Breaking Changes
- Add support for multiple modifiers on the same `Style` by changing `Modifier`
from an enum to a bitflags struct.
So instead of writing:
```rust
let style = Style::default().add_modifier(Modifier::Italic);
```
one should use:
```rust
let style = Style::default().add_modifier(Modifier::ITALIC);
// or
let style = Style::default().add_modifier(Modifier::ITALIC | Modifier::BOLD);
```
### Bug Fixes
- Ensure correct behavior of the alternate screens with the `Crossterm` backend.
- Fix out of bounds panic when two `Buffer` are merged.
## v0.4.0 - 2019-02-03
### Features
- Add a new canvas shape: `Rectangle`.
- Official support of `Crossterm` backend.
- Make it possible to choose the divider between `Tabs`.
- Add word wrapping on Paragraph.
- The gauge widget accepts a ratio (f64 between 0 and 1) in addition of a
percentage.
### Breaking Changes
- Upgrade to Rust 2018 edition.
### Bug Fixes
- Fix rendering of double-width characters.
- Fix race condition on the size of the terminal and expose a size that is
safe to use when drawing through `Frame::size`.
- Prevent unsigned int overflow on large screens.
## v0.3.0 - 2018-11-04
### Features
- Add experimental test backend
## v0.3.0-beta.3 - 2018-09-24
### Features
- `show_cursor` is called when `Terminal` is dropped if the cursor is hidden.
## v0.3.0-beta.2 - 2018-09-23
### Breaking Changes
- Remove custom `termion` backends. This is motivated by the fact that
`termion` structs are meant to be combined/wrapped to provide additional
functionalities to the terminal (e.g AlternateScreen, Mouse support, ...).
Thus providing exclusive types do not make a lot of sense and give a false
hint that additional features cannot be used together. The recommended
approach is now to create your own version of `stdout`:
```rust
let stdout = io::stdout().into_raw_mode()?;
let stdout = MouseTerminal::from(stdout);
let stdout = AlternateScreen::from(stdout);
```
and then to create the corresponding `termion` backend:
```rust
let backend = TermionBackend::new(stdout);
```
The resulting code is more verbose but it works with all combinations of
additional `termion` features.
## v0.3.0-beta.1 - 2018-09-08
### Breaking Changes
- Replace `Item` by a generic and flexible `Text` that can be used in both
`Paragraph` and `List` widgets.
- Remove unnecessary borrows on `Style`.
## v0.3.0-beta.0 - 2018-09-04
### Features
- Add a basic `Crossterm` backend
### Breaking Changes
- Remove `Group` and introduce `Layout` in its place
- `Terminal` is no longer required to compute a layout
- `Size` has been renamed `Constraint`
- Widgets are rendered on a `Frame` instead of a `Terminal` in order to
avoid mixing `draw` and `render` calls
- `draw` on `Terminal` expects a closure where the UI is built by rendering
widgets on the given `Frame`
- Update `Widget` trait
- `draw` takes area by value
- `render` takes a `Frame` instead of a `Terminal`
- All widgets use the consumable builder pattern
- `SelectableList` can have no selected item and the highlight symbol is hidden
in this case
- Remove markup language inside `Paragraph`. `Paragraph` now expects an iterator
of `Text` items
## v0.2.3 - 2018-06-09
### Features
- Add `start_corner` option for `List`
- Add more text alignment options for `Paragraph`
## v0.2.2 - 2018-05-06
### Features

- Generic parameters for `List` to allow passing iterators as items
- Generic parameters for `Table` to allow using iterators as rows and header
- Generic parameters for `Tabs`
- Rename `border` bitflags to `Borders`
