0d54ca06f8 feat: add WidgetExt trait for debugging widgets
Importing the `WidgetExt` trait allows users to easily get a string
representation of a widget with ANSI escape sequences for the terminal.
This is useful for debugging and testing widgets.

```rust
use ratatui::{prelude::*, widgets::widget_ext::WidgetExt};

fn main() {
    let greeting = Text::from(vec![
        Line::styled("Hello", Color::Blue),
        Line::styled("World ", Color::Green),
    ]);
    println!("{}", greeting.to_ansi_string(5, 2));
}
```

## Unreleased
### `StatefulWidgetRef::render_ref` renamed to `render_stateful_ref` [#1184]
[#1184]: https://github.com/ratatui-org/ratatui/pull/1184
This change helps avoid collisions with `WidgetRef::render_ref`.
```diff
trait StatefulWidgetRef {
type State;
- fn render_ref(&self, area: Rect, buf: &mut Buffer, state: &mut Self::State) { }
+ fn render_stateful_ref(&self, area: Rect, buf: &mut Buffer, state: &mut Self::State) { }
}
```
### Prelude items added / removed ([#1149])
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.
This may cause conflicts for types defined elsewhere with a similar
name.
To update your app:
```diff
// if your app uses Styled::style() or Styled::set_style():
-use ratatui::prelude::*;
+use ratatui::{prelude::*, style::Styled};
// if your app uses symbols::Marker:
-use ratatui::prelude::*;
+use ratatui::{prelude::*, symbols::Marker}
// if your app uses terminal::{CompletedFrame, TerminalOptions, Viewport}
-use ratatui::prelude::*;
+use ratatui::{prelude::*, terminal::{CompletedFrame, TerminalOptions, Viewport}};
// to disambiguate existing types named Position or Size:
- use some_crate::{Position, Size};
- let size: Size = ...;
- let position: Position = ...;
+ let size: some_crate::Size = ...;
+ let position: some_crate::Position = ...;
```
[#1149]: https://github.com/ratatui-org/ratatui/pull/1149
### Termion is updated to 4.0 [#1106]
Changelog: <https://gitlab.redox-os.org/redox-os/termion/-/blob/master/CHANGELOG.md>
A change is only necessary if you were matching on all variants of the `MouseEvent` enum without a
wildcard. In this case, you need to either handle the two new variants, `MouseLeft` and
`MouseRight`, or add a wildcard.
[#1106]: https://github.com/ratatui-org/ratatui/pull/1106
### `Rect::inner` takes `Margin` directly instead of reference ([#1008])
[#1008]: https://github.com/ratatui-org/ratatui/pull/1008
`Margin` needs to be passed without reference now.
```diff
-let area = area.inner(&Margin {
+let area = area.inner(Margin {
vertical: 0,
horizontal: 2,
});
```
### `Buffer::filled` takes `Cell` directly instead of reference ([#1148])
[#1148]: https://github.com/ratatui-org/ratatui/pull/1148
`Buffer::filled` moves the `Cell` instead of taking a reference.
```diff
-Buffer::filled(area, &Cell::new("X"));
+Buffer::filled(area, Cell::new("X"));
```
### `Stylize::bg()` now accepts `Into<Color>` ([#1103])
[#1103]: https://github.com/ratatui-org/ratatui/pull/1103
Previously, `Stylize::bg()` accepted `Color` but now accepts `Into<Color>`. This allows more
flexible types from calling scopes, though it can break some type inference in the calling scope.
### Remove deprecated `List::start_corner` and `layout::Corner` ([#759])
[#759]: https://github.com/ratatui-org/ratatui/pull/759
`List::start_corner` was deprecated in v0.25. Use `List::direction` and `ListDirection` instead.
```diff
- list.start_corner(Corner::TopLeft);
- list.start_corner(Corner::TopRight);
// This is not an error, BottomRight rendered top to bottom previously
- list.start_corner(Corner::BottomRight);
// all becomes
+ list.direction(ListDirection::TopToBottom);
```
```diff
- list.start_corner(Corner::BottomLeft);
// becomes
+ list.direction(ListDirection::BottomToTop);
```
`layout::Corner` was removed entirely.

### Run CI tests before pushing a PR
Running `cargo make ci` before pushing will perform the same checks that we do in the CI process.
It's not mandatory to do this before pushing, however it may save you time to do so instead of
waiting for GitHub to run the checks.
We're using [cargo-husky](https://github.com/rhysd/cargo-husky) to automatically run git hooks,
which will run `cargo make ci` before each push. To initialize the hook run `cargo test`. If
`cargo-make` is not installed, it will provide instructions to install it for you. This will ensure
that your code is formatted, compiles and passes all tests before you push. If you need to skip this
check, you can use `git push --no-verify`.
