This introduces a new `ratatui::run()` method which runs a closure with
a terminal initialized with reasonable defaults for most applications.
This calls `ratatui::init()` before running the closure and
`ratatui::restore()` after the closure completes, and returns the result
of the closure.
A minimal hello world example using the new `ratatui::run()` method:
```rust
fn main() -> Result<(), Box<dyn std::error::Error>> {
ratatui::run(|terminal| {
loop {
terminal.draw(|frame| frame.render_widget("Hello World!", frame.area()))?;
if crossterm::event::read()?.is_key_press() {
break Ok(());
}
}
})
}
```
Of course, this also works both with apps that use free methods and
structs:
```rust
fn run(terminal: &mut DefaultTerminal) -> Result<(), AppError> { ... }
ratatui::run(run)?;
```
```rust
struct App { ... }
impl App {
fn new() -> Self { ... }
fn run(mut self, terminal: &mut DefaultTerminal) -> Result<(), AppError> { ... }
}
ratatui::run(|terminal| App::new().run(terminal))?;
```
Crossterm 0.29 introduced methods to easily check / extract the event
type. E.g. as_key_press_event() and is_key_press(). This commit
updates the examples to use these methods instead of matching on
the event type. This makes the code cleaner and easier to read.
Also does a general cleanup of the event handling code in the examples.
I was swayed by the arguments about this made by the compiler team In
<https://github.com/rust-lang/compiler-team/issues/750> and decided to
look at how this organization affects ratatui. I found this reduces the
number of lines across the codebase by about 350 and makes the imports
more readable and definitely more greppable as you usually only have
to read a single line. I've found in the past that maintaining imports
regularly leads to merge conflicts which have to be resolved by hand
and this change should reduce the likelihood of that happening.
Main change is in rustfmt.toml, and the rest is just the result of
running `cargo xtask format`.
While implementing this, cargo machete brings up that the various
backend crates are unused by the example crates.
The re-export of each backend crate under ratatui is to make it possible
for libs that rely on a specific version of ratatui to use the same
version of the backend crate. Apps in general should use the backend
crate directly rather than through ratatui as this is less confusing.
- Removes all usages of `ratatui::{crossterm, termion, termwiz}`` in the
examples.
- Adds the backend crate to the dependencies of the examples that use
the backend crate directly.
