## [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.

- *(uncategorized)* Expand serde attributes for `TestBuffer` ([#389](https://github.com/ratatui-org/ratatui/issues/389))
([57ea871](https://github.com/ratatui-org/ratatui/commit/57ea871753a5b23f302c6f0a83d98f6a1988abfb))
- *(uncategorized)* Add weak constraints to make rects closer to each other in size ✨ ([#395](https://github.com/ratatui-org/ratatui/issues/395))
([6153371](https://github.com/ratatui-org/ratatui/commit/61533712be57f3921217a905618b319975f90330))

### Bug Fixes
- *(barchart)* Empty groups causes panic ([#333](https://github.com/ratatui-org/ratatui/issues/333))
([9c95673](https://github.com/ratatui-org/ratatui/commit/9c956733f740b18616974e2c7d786ca761666f79))
````text
This unlikely to happen, since nobody wants to add an empty group.
Even we fix the panic, things will not render correctly.
So it is better to just not add them to the BarChart.
````
- *(block)* Fixed title_style not rendered ([#349](https://github.com/ratatui-org/ratatui/issues/349)) ([#363](https://github.com/ratatui-org/ratatui/issues/363))
([49a82e0](https://github.com/ratatui-org/ratatui/commit/49a82e062f2c46dc3060cdfdb230b65d9dbfb2d9))
- *(cargo)* Adjust minimum paste version ([#348](https://github.com/ratatui-org/ratatui/issues/348))
([8db9fb4](https://github.com/ratatui-org/ratatui/commit/8db9fb4aebd01e5ddc4edd68482361928f7e9c97))
````text
ratatui is using features that are currently only available in paste 1.0.2; specifying the minimum version to be 1.0 will consequently cause a compilation error if cargo is only able to use a version less than 1.0.2.

([daf5890](https://github.com/ratatui-org/ratatui/commit/daf589015290ac8b379389d29ef90a1af15e3f75))

````
- *(layout)* Don't leave gaps between chunks ([#408](https://github.com/ratatui-org/ratatui/issues/408))
([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.
````
- *(layout)* Ensure left <= right ([#410](https://github.com/ratatui-org/ratatui/issues/410))
([f4ed3b7](https://github.com/ratatui-org/ratatui/commit/f4ed3b758450ef9c257705f3a1ea937329a968b4))

````text
The symbols and sets are moved from `widgets::scrollbar` to
`symbols::scrollbar`. This makes it consistent with the other symbol
sets and allows us to make the scrollbar module private rather than
re-exporting it.
````
- *(table)* Fix unit tests broken due to rounding ([#419](https://github.com/ratatui-org/ratatui/issues/419))
([dc55211](https://github.com/ratatui-org/ratatui/commit/dc552116cf5e83c7ffcc2f5299c00d2315490c1d))
````text

concise while adding comments to help clarify that the rounding behavior
is working as expected.
````
- *(uncategorized)* Correct minor typos in documentation ([#331](https://github.com/ratatui-org/ratatui/issues/331))

````text
Calculating the label_offset is unnecessary, if we just render the
group label after rendering the bars. We can just reuse bar_y.
````
- *(layout)* Simplify and doc split() ([#405](https://github.com/ratatui-org/ratatui/issues/405))
([de25de0](https://github.com/ratatui-org/ratatui/commit/de25de0a9506e53df1378929251594bccf63d932))
````text
* test(layout): add tests for split()
* refactor(layout): simplify and doc split()
This is mainly a reduction in density of the code with a goal of
improving mainatainability so that the algorithm is clear.

- *(layout)* Simplify split() function ([#396](https://github.com/ratatui-org/ratatui/issues/396))
([5195099](https://github.com/ratatui-org/ratatui/commit/519509945be866c3b2f6a4230ee317262266f894))

([add578a](https://github.com/ratatui-org/ratatui/commit/add578a7d6d342e3ebaa26e69452a2ab5b08b0c7))
````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).

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`.

### 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

- Drop `log4rs` as a dev-dependencies in favor of `stderrlog`
### Breaking Changes
- Rename `TermionBackend` to `RawBackend` (to distinguish it from the `MouseBackend`)
- 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`
