## [0.25.0](https://github.com/ratatui-org/ratatui/releases/tag/0.25.0) - 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/>

### Features

- [aef4956](https://github.com/ratatui-org/ratatui/commit/aef495604c52e563fbacfb1a6e730cd441a99129)
  *(list)* `List::new` now accepts `IntoIterator<Item = Into<ListItem>>` ([#672](https://github.com/ratatui-org/ratatui/issues/672)) [**breaking**]

  ````text
  This allows to build list like

  ```
  List::new(["Item 1", "Item 2"])
  ```
  ````

- [8bfd666](https://github.com/ratatui-org/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-org/ratatui/commit/1229b96e428df880a951ef57f53ca73e74ef1ea2)
  *(rect)* Add `offset` method ([#533](https://github.com/ratatui-org/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-org/ratatui/commit/edacaf7ff4e4b14702f6361af5a6da713b7dc564)
  *(buffer)* Deprecate `Cell::symbol` field ([#624](https://github.com/ratatui-org/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-org/ratatui/commit/6b2efd0f6c3bf56dc06bbf042db40c0c66de577e)
  *(layout)* Accept IntoIterator for constraints ([#663](https://github.com/ratatui-org/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-org/ratatui/commit/753e246531e1e9e2ea558911f8d03e738901d85f)
  *(layout)* Allow configuring layout fill ([#633](https://github.com/ratatui-org/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.

  Fixes https://github.com/ratatui-org/ratatui/issues/536

- [1e2f0be](https://github.com/ratatui-org/ratatui/commit/1e2f0be75ac3fb3d6500c1de291bd49972b808e4)
  *(layout)* Add parameters to Layout::new() ([#557](https://github.com/ratatui-org/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),
  ]);
  ```

- [c862aa5](https://github.com/ratatui-org/ratatui/commit/c862aa5e9ef4dbf494b5151214ac87f5c71e76d4)
  *(list)* Support line alignment ([#599](https://github.com/ratatui-org/ratatui/issues/599))

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

- [4424637](https://github.com/ratatui-org/ratatui/commit/4424637af252dc2f227fe4956eac71135e60fb02)
  *(span)* Add setters for content and style ([#647](https://github.com/ratatui-org/ratatui/issues/647))

- [ebf1f42](https://github.com/ratatui-org/ratatui/commit/ebf1f4294211d478b8633a06576ec269a50db588)
  *(style)* Implement `From` trait for crossterm to `Style` related structs ([#686](https://github.com/ratatui-org/ratatui/issues/686))

- [e49385b](https://github.com/ratatui-org/ratatui/commit/e49385b78c8e01fe6381b19d15137346bc6eb8a1)
  *(table)* Add a Table::segment_size method ([#660](https://github.com/ratatui-org/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.
  ````

- [b8f71c0](https://github.com/ratatui-org/ratatui/commit/b8f71c0d6eda3da272d29c7a9b3c47181049f76a)
  *(widgets/chart)* Add option to set the position of legend ([#378](https://github.com/ratatui-org/ratatui/issues/378))

- [5bf4f52](https://github.com/ratatui-org/ratatui/commit/5bf4f52119ab3e0e3a266af196058179dc1d18c3)
  *(uncategorized)* Implement `From` trait for termion to `Style` related structs ([#692](https://github.com/ratatui-org/ratatui/issues/692))

  ````text
  * feat(termion): implement from termion color

  * feat(termion): implement from termion style

  * feat(termion): implement from termion `Bg` and `Fg`
  ````

- [d19b266](https://github.com/ratatui-org/ratatui/commit/d19b266e0eabdb0fb00660439a1818239c94024b)
  *(uncategorized)* Add Constraint helpers (e.g. from_lengths) ([#641](https://github.com/ratatui-org/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]);
  ```

- [56fc410](https://github.com/ratatui-org/ratatui/commit/56fc4101056e0f631f563f8f2c07646063e650d3)
  *(block)* Make `inner` aware of title positions ([#657](https://github.com/ratatui-org/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.

- [37c70db](https://github.com/ratatui-org/ratatui/commit/37c70dbb8e19c0fb35ced16b29751933514a441e)
  *(table)* Add widths parameter to new() ([#664](https://github.com/ratatui-org/ratatui/issues/664)) [**breaking**]

  ````text
  This prevents creating a table that doesn't actually render anything.

  *(table)* Fix new clippy lint which triggers on table widths tests ([#630](https://github.com/ratatui-org/ratatui/issues/630))

  ````text
  * fix(table): new clippy lint in 1.74.0 triggers on table widths tests
  ````

- [36d8c53](https://github.com/ratatui-org/ratatui/commit/36d8c5364590a559913c40ee5f021b5d8e3466e6)
  *(table)* Widths() now accepts AsRef<[Constraint]> ([#628](https://github.com/ratatui-org/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-org/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.

  *(tabs)* Tab widget now supports custom padding ([#629](https://github.com/ratatui-org/ratatui/issues/629))

  ````text
  The Tab widget now contains padding_left and and padding_right
  properties. Those values can be set with functions `padding_left()`,
  `padding_right()`, and `padding()` which all accept `Into<Line>`.

  *(list)* `start_corner` is now `direction` ([#673](https://github.com/ratatui-org/ratatui/issues/673))

  ````text
  The previous name `start_corner` did not communicate clearly the intent of the method.
  A new method `direction` and a new enum `ListDirection` were added.

  `start_corner` is now deprecated

  *(layout)* To natural reading order ([#681](https://github.com/ratatui-org/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.

## [0.24.0](https://github.com/ratatui-org/ratatui/releases/tag/0.24.0) - 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-org/ratatui/blob/main/BREAKING-CHANGES.md) ⚠️.
Also, we created various tutorials and walkthroughs in [Ratatui Book](https://github.com/ratatui-org/ratatui-book) which is available at <https://ratatui.rs> 🚀

✨ **Release highlights**: <https://ratatui.rs/highlights/v024>

### Features

- [c6c3f88](https://github.com/ratatui-org/ratatui/commit/c6c3f88a79515a085fb8a96fe150843dab6dd5bc)
  _(backend)_ Implement common traits for `WindowSize` ([#586](https://github.com/ratatui-org/ratatui/issues/586))

- [d077903](https://github.com/ratatui-org/ratatui/commit/d0779034e741834aac36b5b7a87c54bd8c50b7f2)
  _(backend)_ Backend provides window_size, add Size struct ([#276](https://github.com/ratatui-org/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-org/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-org#513
  ```

  _(block)_ Allow custom symbols for borders ([#529](https://github.com/ratatui-org/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-org/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-org/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
  * feat(line): add `Line::raw` constructor

  There is already `Span::raw` and `Text::raw` methods
  and this commit simply adds `Line::raw` method for symmetry.

  Multi-line content is converted to multiple spans with the new line removed

  ```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.

### Bug Fixes

- [638d596](https://github.com/ratatui-org/ratatui/commit/638d596a3b7aec723a2354cf0e261b207ac412f8)
  _(layout)_ Use LruCache for layout cache ([#487](https://github.com/ratatui-org/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-org/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"] }
  ```

  ```text

  fixed by only setting the style for the width of the text, and not the
  entire row.

  _(stylize)_ Add Stylize impl for String ([#466](https://github.com/ratatui-org/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

  ```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-org/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-org/ratatui/issues/325))
([0dca6a6](https://github.com/ratatui-org/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-org/ratatui/issues/215))
([e4bcf78](https://github.com/ratatui-org/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.

([56455e0](https://github.com/ratatui-org/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,
  whereas previously it would have left odd gaps between columns.

  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

  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).

  Run all the tests rather than canceling when one test fails. This allows
  us to see all the failures, rather than just the first one if there are
  multiple. Specifically this is useful when we have an issue in one
  toolchain or backend.

## 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).

### Fixes

- Apply label style in `widgets::Gauge` and avoid panics because of overflows with long labels (#494).
- Avoid panics because of overflows with long axis labels in `widgets::Chart` (#512).
- Fix computation of column widths in `widgets::Table` (#514).
- Fix panics because of invalid offset when input changes between two frames in `widgets::List` and
  `widgets::Chart` (#516).

## v0.15.0 - 2021-05-02

### Features

- Update `crossterm` to `0.19`.
- Update `rand` to `0.8`.
- Add a read-only view of the terminal state after the draw call (#440).

### Fixes

- Remove compile warning in `TestBackend::assert_buffer` (#466).

## v0.14.0 - 2021-01-01

### Breaking changes

#### 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

- `Terminal` implements `Debug`

### Breaking Changes

- Use `FnOnce` instead of `FnMut` in Group::render
