The `Row::new` constructor accepts a single argument that implements
`IntoIterator`. This commit adds an implementation of `FromIterator`,
as a thin wrapper around `Row::new`. This allows `.collect::<Row>()`
to be used at the end of an iterator chain, rather than wrapping the
entire iterator chain in `Row::new`.
* 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
keep it constrained to a certain area.
For example, this can be used to implement a draggable window that can
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;
```
* refactor: use rstest to simplify clamp test
* fix: use rstest description instead of string
test layout::rect::tests:🗜️:case_01_inside ... ok
test layout::rect::tests:🗜️:case_02_up_left ... ok
test layout::rect::tests:🗜️:case_04_up_right ... ok
test layout::rect::tests:🗜️:case_05_left ... ok
test layout::rect::tests:🗜️:case_03_up ... ok

test layout::rect::tests:🗜️:case_09_down_right ... ok
test layout::rect::tests:🗜️:case_10_too_wide ... ok
test layout::rect::tests:🗜️:case_11_too_tall ... ok
test layout::rect::tests:🗜️:case_12_too_large ... ok
* fix: less ambiguous docs for this / other rect
* fix: move rstest to dev deps
This avoid creating a block with no borders and then settings Borders::ALL. i.e.
```diff
- Block::default().borders(Borders::ALL);
+ Block::bordered();
```
This method splits a Rect and returns a fixed-size array of the
resulting Rects. This allows the caller to use array destructuring
to get the individual Rects.
```rust
use Constraint::*;
let layout = &Layout::vertical([Length(1), Min(0)]);
let [top, main] = area.split(&layout);
```
This allows Table constructors to accept any type that implements
Into<Constraint> instead of just AsRef<Constraint>. This is useful when
you want to specify a fixed size for a table columns, but don't want to
explicitly create a Constraint::Length yourself.
```rust
Table::new(rows, [1,2,3])
Table::default().widths([1,2,3])
```
This allows Layout constructors to accept any type that implements
Into<Constraint> instead of just AsRef<Constraint>. This is useful when
you want to specify a fixed size for a layout, but don't want to
explicitly create a Constraint::Length yourself.
```rust
Layout::new(Direction::Vertical, [1, 2, 3]);
Layout::horizontal([1, 2, 3]);
Layout::vertical([1, 2, 3]);
Layout::default().constraints([1, 2, 3]);
```
* feat(layout): add vertical and horizontal constructors
This commit adds two new constructors to the `Layout` struct, which
allow the user to create a vertical or horizontal layout with default
values.
```rust
let layout = Layout::vertical([
Constraint::Length(10),
Constraint::Min(5),
Constraint::Length(10),
]);
let layout = Layout::horizontal([
Constraint::Length(10),
Constraint::Min(5),
Constraint::Length(10),
]);
```
Important note: this also fixes a wrong mapping between ratatui's gray
and termwiz's grey. `ratatui::Color::Gray` now maps to
`termwiz::color::AnsiColor::Silver`
* 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-org/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

At close to 2000 lines of code, the table widget was getting a bit
unwieldy. This commit splits it into multiple files, one for each
struct, and one for the table itself.
Also refactors the table rendering code to be easier to maintain.
This allows us to use Line as a child of other widgets, and to use
Line::render() to render it rather than calling buffer.set_line().
```rust
frame.render_widget(Line::raw("Hello, world!"), area);
// or
Line::raw("Hello, world!").render(frame, area);
```
- The `Line` struct now stores the style of the line rather than each
`Span` storing it.
- Adds two new setters for style and spans
- Adds missing docs
BREAKING CHANGE: `Line::style` is now a field of `Line` instead of being
stored in each `Span`.
Previously, if `.widths` was not called before rendering a `Table`, no
content would render in the area of the table. This commit changes that
behaviour to default to equal widths for each column.
Fixes#510.

The deserialize implementation for Color used to support only the enum
names (e.g. Color, LightRed, etc.) With this change, you can use any of
the strings supported by the FromStr implementation (e.g. black,
light-red, #00ff00, etc.)
Automatically detect breaking changes based on commit messages
and bump the alpha release number accordingly.
E.g. v0.23.1-alpha.1 will be bumped to v0.24.0-alpha.0 if any commit
since v0.23.0 has a breaking change.
- Refactor the `table` module for better top to bottom readability by
putting types first and arranging them in a logical order (Table, Row,
Cell, other).
- Adds new methods for:
- `Table::rows`
- `Row::cells`
- `Cell::new`
- `Cell::content`
- `TableState::new`
- `TableState::selected_mut`
- Makes `HighlightSpacing::should_add` pub(crate) since it's an internal
detail.
- Adds tests for all the new methods and simple property tests for all
the other setter methods.
