### `FrameExt` trait for `unstable-widget-ref` feature ([#1530])
|
||||
|
||||
[#1530]: https://github.com/ratatui/ratatui/pull/1530
|
||||
|
||||
To call `Frame::render_widget_ref()` or `Frame::render_stateful_widget_ref()` you now need to:
|
||||
|
||||
1. Import the `FrameExt` trait from `ratatui::widgets`.
|
||||
2. Enable the `unstable-widget-ref` feature.
|
||||
|
||||
For example:
|
||||
|
||||
```rust
|
||||
use ratatui::{
|
||||
layout::Rect,
|
||||
widgets::{Block, FrameExt},
|
||||
};
|
||||
|
||||
let block = Block::new();
|
||||
let area = Rect::new(0, 0, 5, 5);
|
||||
frame.render_widget_ref(&block, area);
|
||||
```
|
||||
|
||||
### `WidgetRef` no longer has a blanket implementation of Widget
|
||||
|
||||
Previously there was a blanket implementation of Widget for WidgetRef. This has been reversed to
|
||||
instead be a blanket implementation of WidgetRef for all &W where W: Widget. Any widgets that
|
||||
previously implemented WidgetRef directly should now instead implement Widget for a reference to the
|
||||
type.
|
||||
|
||||
```diff
|
||||
-impl WidgetRef for Foo {
|
||||
- fn render_ref(&self, area: Rect, buf: &mut Buffer)
|
||||
+impl Widget for &Foo {
|
||||
+ fn render(self, area: Rect, buf: &mut Buffer)
|
||||
}
|
||||
```
|
||||
|
||||
### The `From` impls for backend types are now replaced with more specific traits [#1464]
|
||||
|
||||
[#1464]: https://github.com/ratatui/ratatui/pull/1464
|
||||
|
||||
Crossterm gains `ratatui::backend::crossterm::{FromCrossterm, IntoCrossterm}`
|
||||
Termwiz gains `ratatui::backend::termwiz::{FromTermwiz, IntoTermwiz}`
|
||||
|
||||
This is necessary in order to avoid the orphan rule when implementing `From` for crossterm types
|
||||
once the crossterm types are moved to a separate crate.
|
||||
|
||||
```diff
|
||||
+ use ratatui::backend::crossterm::{FromCrossterm, IntoCrossterm};
|
||||
|
||||
let crossterm_color = crossterm::style::Color::Black;
|
||||
- let ratatui_color = crossterm_color.into();
|
||||
- let ratatui_color = ratatui::style::Color::from(crossterm_color);
|
||||
+ let ratatui_color = ratatui::style::Color::from_crossterm(crossterm_color);
|
||||
- let crossterm_color = ratatui_color.into();
|
||||
- let crossterm_color = crossterm::style::Color::from(ratatui_color);
|
||||
+ let crossterm_color = ratatui_color.into_crossterm();
|
||||
|
||||
let crossterm_attribute = crossterm::style::types::Attribute::Bold;
|
||||
- let ratatui_modifier = crossterm_attribute.into();
|
||||
- let ratatui_modifier = ratatui::style::Modifier::from(crossterm_attribute);
|
||||
+ let ratatui_modifier = ratatui::style::Modifier::from_crossterm(crossterm_attribute);
|
||||
- let crossterm_attribute = ratatui_modifier.into();
|
||||
- let crossterm_attribute = crossterm::style::types::Attribute::from(ratatui_modifier);
|
||||
+ let crossterm_attribute = ratatui_modifier.into_crossterm();
|
||||
```
|
||||
|
||||
Similar conversions for `ContentStyle` -> `Style` and `Attributes` -> `Modifier` exist for
|
||||
Crossterm and the various Termion and Termwiz types as well.
|
||||
|
||||
### `Bar::label()` and `BarGroup::label()` now accepts `Into<Line<'a>>`. ([#1471])
|
||||
|
||||
[#1471]: https://github.com/ratatui/ratatui/pull/1471
|
||||
|
||||
Previously `Bar::label()` and `BarGroup::label()` accepted `Line<'a>`, but they now accepts `Into<Line<'a>>`.
|
||||
|
||||
for `Bar::label()`:
|
||||
|
||||
```diff
|
||||
- Bar::default().label("foo".into());
|
||||
+ Bar::default().label("foo");
|
||||
```
|
||||
|
||||
for `BarGroup::label()`:
|
||||
|
||||
```diff
|
||||
- BarGroup::default().label("bar".into());
|
||||
+ BarGroup::default().label("bar");
|
||||
```
|
||||
|
||||
### `Bar::text_value` now accepts `Into<String>` ([#1471])
|
||||
|
||||
Previously `Bar::text_value` accepted `String`, but now it accepts `Into<String>`.
|
||||
|
||||
for `Bar::text_value()`:
|
||||
|
||||
```diff
|
||||
- Bar::default().text_value("foobar".into());
|
||||
+ Bar::default().text_value("foobar");
|
||||
```
|
||||
|
||||
## [v0.29.0](https://github.com/ratatui/ratatui/releases/tag/v0.29.0)
|
||||
|
||||
### `Sparkline::data` takes `IntoIterator<Item = SparklineBar>` instead of `&[u64]` and is no longer const ([#1326])
|
||||
|
||||
[#1326]: https://github.com/ratatui/ratatui/pull/1326
|
||||
|
||||
The `Sparkline::data` method has been modified to accept `IntoIterator<Item = SparklineBar>`
|
||||
instead of `&[u64]`.
|
||||
|
||||
`SparklineBar` is a struct that contains an `Option<u64>` value, which represents an possible
|
||||
_absent_ value, as distinct from a `0` value. This change allows the `Sparkline` to style
|
||||
data points differently, depending on whether they are present or absent.
|
||||
|
||||
`SparklineBar` also contains an `Option<Style>` that will be used to apply a style the bar in
|
||||
addition to any other styling applied to the `Sparkline`.
|
||||
|
||||
Several `From` implementations have been added to `SparklineBar` to support existing callers who
|
||||
provide `&[u64]` and other types that can be converted to `SparklineBar`, such as `Option<u64>`.
|
||||
|
||||
If you encounter any type inference issues, you may need to provide an explicit type for the data
|
||||
passed to `Sparkline::data`. For example, if you are passing a single value, you may need to use
|
||||
`into()` to convert it to form that can be used as a `SparklineBar`:
|
||||
|
||||
```diff
|
||||
let value = 1u8;
|
||||
- Sparkline::default().data(&[value.into()]);
|
||||
+ Sparkline::default().data(&[u64::from(value)]);
|
||||
```
|
||||
|
||||
As a consequence of this change, the `data` method is no longer a `const fn`.
|
||||
|
||||
### `Color::from_hsl` is now behind the `palette` feature and accepts `palette::Hsl` ([#1418])
|
||||

### Removed public fields from `Rect` iterators ([#1358], [#1424])

[#1358]: https://github.com/ratatui/ratatui/pull/1358
|
||||
[#1424]: https://github.com/ratatui/ratatui/pull/1424
|
||||
|
||||
The `pub` modifier has been removed from fields on the `Columns`,`Rows`, and `Positions` iterators.
|
||||
These fields were not intended to be public and should not have been accessed directly.

### `Rect::area()` now returns u32 instead of u16 ([#1378])
|
||||
|

[#1378]: https://github.com/ratatui/ratatui/pull/1378
|
||||
|
||||
This is likely to impact anything which relies on `Rect::area` maxing out at u16::MAX. It can now

return up to u16::MAX * u16::MAX (2^32 - 2^17 + 1).

As this adds an extra conversion, ambiguous inferred expressions may no longer compile.

|
||||
|
||||
[#1413]: https://github.com/ratatui/ratatui/pull/1413
|
||||
|
||||
Previously `Tabs::select()` accepted `usize`, but it now accepts `Into<Option<usize>>`. This breaks
|
||||
any code already using parameter type inference:
|
||||
|
||||
```diff
|
||||
let selected = 1u8;
|
||||
- let tabs = Tabs::new(["A", "B"]).select(selected.into())

||||

### `Table::highlight_style` is now `Table::row_highlight_style` ([#1331])
|
||||
|
||||
[#1331]: https://github.com/ratatui/ratatui/pull/1331
|
||||
|
||||
The `Table::highlight_style` is now deprecated in favor of `Table::row_highlight_style`.
|
||||
|
||||
Also, the serialized output of the `TableState` will now include the "selected_column" field.
|
||||
Software that manually parse the serialized the output (with anything other than the `Serialize`
|
||||
implementation on `TableState`) may have to be refactored if the "selected_column" field is not
|
||||
accounted for. This does not affect users who rely on the `Deserialize`, or `Serialize`
|

implementation on the state.

# Ratatui
|
||||
|
||||
[Ratatui][Ratatui Website] is a crate for cooking up terminal user interfaces in Rust. It is a
|
||||
lightweight library that provides a set of widgets and utilities to build complex Rust TUIs.
|
||||
Ratatui was forked from the [tui-rs] crate in 2023 in order to continue its development.
|
||||
|
||||
## Installation
|
||||
|
||||
Add `ratatui` as a dependency to your cargo.toml:
|
||||
|
||||
```shell
|
||||
cargo add ratatui
|
||||
```
|
||||
|
||||
Ratatui uses [Crossterm] by default as it works on most platforms. See the [Installation]
|
||||
section of the [Ratatui Website] for more details on how to use other backends ([Termion] /
|
||||
[Termwiz]).
|
||||
|
||||
## Introduction
|
||||
|
||||
Ratatui is based on the principle of immediate rendering with intermediate buffers. This means
|
||||
that for each frame, your app must render all widgets that are supposed to be part of the UI.
|
||||
This is in contrast to the retained mode style of rendering where widgets are updated and then
|
||||
automatically redrawn on the next frame. See the [Rendering] section of the [Ratatui Website]
|
||||
for more info.
|
||||
|
||||
You can also watch the [FOSDEM 2024 talk] about Ratatui which gives a brief introduction to
|
||||
terminal user interfaces and showcases the features of Ratatui, along with a hello world demo.
|
||||
|
||||

|
||||
[Ratatui][Ratatui Website] (_ˌræ.təˈtu.i_) is a Rust crate for cooking up terminal user interfaces
|
||||
(TUIs). It provides a simple and flexible way to create text-based user interfaces in the terminal,
|
||||
which can be used for command-line applications, dashboards, and other interactive console programs.
|
||||
|
||||
## Quickstart
|
||||
|
||||
The following example demonstrates the minimal amount of code necessary to setup a terminal and
|
||||
render "Hello World!". The full code for this example which contains a little more detail is in
|
||||
the [Examples] directory. For more guidance on different ways to structure your application see
|
||||
the [Application Patterns] and [Hello World tutorial] sections in the [Ratatui Website] and the
|
||||
various [Examples]. There are also several starter templates available in the [templates]
|
||||

Ratatui has [templates] available to help you get started quickly. You can use the
|
||||
[`cargo-generate`] command to create a new project with Ratatui:
|
||||
|
||||
Every application built with `ratatui` needs to implement the following steps:
|
||||
```shell
|
||||
cargo install --locked cargo-generate
|
||||
cargo generate ratatui/templates
|
||||
```
|
||||
|
||||
- Initialize the terminal
|
||||
- A main loop to:
|
||||
- Handle input events
|
||||
- Draw the UI
|
||||
- Restore the terminal state
|
||||
|
||||
The library contains a [`prelude`] module that re-exports the most commonly used traits and
|
||||
types for convenience. Most examples in the documentation will use this instead of showing the
|
||||
full path of each type.
|
||||
|
||||
### Initialize and restore the terminal
|
||||
|
||||
The [`Terminal`] type is the main entry point for any Ratatui application. It is a light
|
||||
abstraction over a choice of [`Backend`] implementations that provides functionality to draw
|
||||
each frame, clear the screen, hide the cursor, etc. It is parametrized over any type that
|
||||
implements the [`Backend`] trait which has implementations for [Crossterm], [Termion] and
|
||||
[Termwiz].
|
||||
|
||||
Most applications should enter the Alternate Screen when starting and leave it when exiting and
|
||||
also enable raw mode to disable line buffering and enable reading key events. See the [`backend`
|
||||
module] and the [Backends] section of the [Ratatui Website] for more info.
|
||||
|
||||
### Drawing the UI
|
||||
|
||||
The drawing logic is delegated to a closure that takes a [`Frame`] instance as argument. The
|
||||
[`Frame`] provides the size of the area to draw to and allows the app to render any [`Widget`]
|
||||
using the provided [`render_widget`] method. After this closure returns, a diff is performed and
|
||||
only the changes are drawn to the terminal. See the [Widgets] section of the [Ratatui Website]
|
||||
for more info.
|
||||
|
||||
### Handling events
|
||||
|
||||
Ratatui does not include any input handling. Instead event handling can be implemented by
|
||||
calling backend library methods directly. See the [Handling Events] section of the [Ratatui
|
||||
Website] for more info. For example, if you are using [Crossterm], you can use the
|
||||
[`crossterm::event`] module to handle events.
|
||||
|
||||
### Example
|
||||
Selecting the Hello World template produces the following application:
|
||||
|
||||
```rust
|
||||
use std::io::{self, stdout};
|
||||
use color_eyre::Result;
|
||||
use crossterm::event::{self, Event};
|
||||
use ratatui::{DefaultTerminal, Frame};
|
||||
|
||||
use ratatui::{
|
||||
backend::CrosstermBackend,
|
||||
crossterm::{
|
||||
event::{self, Event, KeyCode},
|
||||
terminal::{
|
||||
disable_raw_mode, enable_raw_mode, EnterAlternateScreen, LeaveAlternateScreen,
|
||||
},
|
||||
ExecutableCommand,
|
||||
},
|
||||
widgets::{Block, Paragraph},
|
||||
Frame, Terminal,
|
||||
};
|
||||
|
||||
fn main() -> io::Result<()> {
|
||||
enable_raw_mode()?;
|
||||
stdout().execute(EnterAlternateScreen)?;
|
||||
let mut terminal = Terminal::new(CrosstermBackend::new(stdout()))?;
|
||||
|
||||
let mut should_quit = false;
|
||||
while !should_quit {
|
||||
terminal.draw(ui)?;
|
||||
should_quit = handle_events()?;
|
||||
}
|
||||
|
||||
disable_raw_mode()?;
|
||||
stdout().execute(LeaveAlternateScreen)?;
|
||||
Ok(())
|
||||
fn main() -> Result<()> {
|
||||
color_eyre::install()?;
|
||||
let terminal = ratatui::init();
|
||||
let result = run(terminal);
|
||||
ratatui::restore();
|
||||
result
|
||||
}
|
||||
|
||||
fn handle_events() -> io::Result<bool> {
|
||||
if event::poll(std::time::Duration::from_millis(50))? {
|
||||
if let Event::Key(key) = event::read()? {
|
||||
if key.kind == event::KeyEventKind::Press && key.code == KeyCode::Char('q') {
|
||||
return Ok(true);
|
||||
}
|
||||
fn run(mut terminal: DefaultTerminal) -> Result<()> {
|
||||
loop {
|
||||
terminal.draw(render)?;
|
||||
if matches!(event::read()?, Event::Key(_)) {
|
||||
break Ok(());
|
||||
}
|
||||
}
|
||||
Ok(false)
|
||||
}
|
||||
|
||||
fn ui(frame: &mut Frame) {
|
||||
frame.render_widget(
|
||||
Paragraph::new("Hello World!").block(Block::bordered().title("Greeting")),
|
||||
frame.size(),
|
||||
);
|
||||
fn render(frame: &mut Frame) {
|
||||
frame.render_widget("hello world", frame.area());
|
||||
}
|
||||
```
|
||||

## Layout
|
||||
You can also watch the [EuroRust 2024 talk] to learn about common concepts in Ratatui and what's
|
||||
possible to build with it.
|
||||
|
||||
The library comes with a basic yet useful layout management object called [`Layout`] which
|
||||
allows you to split the available space into multiple areas and then render widgets in each
|
||||
area. This lets you describe a responsive terminal UI by nesting layouts. See the [Layout]
|
||||
section of the [Ratatui Website] for more info.
|
||||
## Templates
|
||||
|
||||
```rust
|
||||
use ratatui::{
|
||||
layout::{Constraint, Layout},
|
||||
widgets::Block,
|
||||
Frame,
|
||||
};
|
||||
If you're looking to get started quickly, you can use one of the available templates from the
|
||||
[templates] repository using [`cargo-generate`]:
|
||||
|
||||
fn ui(frame: &mut Frame) {
|
||||
let [title_area, main_area, status_area] = Layout::vertical([
|
||||
Constraint::Length(1),
|
||||
Constraint::Min(0),
|
||||
Constraint::Length(1),
|
||||
])
|
||||
.areas(frame.size());
|
||||
let [left_area, right_area] =
|
||||
Layout::horizontal([Constraint::Percentage(50), Constraint::Percentage(50)])
|
||||
.areas(main_area);
|
||||
|
||||
frame.render_widget(Block::bordered().title("Title Bar"), title_area);
|
||||
frame.render_widget(Block::bordered().title("Status Bar"), status_area);
|
||||
frame.render_widget(Block::bordered().title("Left"), left_area);
|
||||
frame.render_widget(Block::bordered().title("Right"), right_area);
|
||||
}
|
||||
```shell
|
||||
cargo generate ratatui/templates
|
||||
```
|
||||
|
||||
Running this example produces the following output:

|
||||
|
||||
## Text and styling
|
||||
|
||||
The [`Text`], [`Line`] and [`Span`] types are the building blocks of the library and are used in
|
||||
many places. [`Text`] is a list of [`Line`]s and a [`Line`] is a list of [`Span`]s. A [`Span`]
|
||||
is a string with a specific style.
|
||||
|
||||
The [`style` module] provides types that represent the various styling options. The most
|
||||
important one is [`Style`] which represents the foreground and background colors and the text
|
||||
attributes of a [`Span`]. The [`style` module] also provides a [`Stylize`] trait that allows
|
||||
short-hand syntax to apply a style to widgets and text. See the [Styling Text] section of the
|
||||
[Ratatui Website] for more info.
|
||||
|
||||
```rust
|
||||
use ratatui::{
|
||||
layout::{Constraint, Layout},
|
||||
style::{Color, Modifier, Style, Stylize},
|
||||
text::{Line, Span},
|
||||
widgets::{Block, Paragraph},
|
||||
Frame,
|
||||
};
|
||||
|
||||
fn ui(frame: &mut Frame) {
|
||||
let areas = Layout::vertical([Constraint::Length(1); 4]).split(frame.size());
|
||||
|
||||
let line = Line::from(vec![
|
||||
Span::raw("Hello "),
|
||||
Span::styled(
|
||||
"World",
|
||||
Style::new()
|
||||
.fg(Color::Green)
|
||||
.bg(Color::White)
|
||||
.add_modifier(Modifier::BOLD),
|
||||
),
|
||||
"!".red().on_light_yellow().italic(),
|
||||
]);
|
||||
frame.render_widget(line, areas[0]);
|
||||
|
||||
// using the short-hand syntax and implicit conversions
|
||||
let paragraph = Paragraph::new("Hello World!".red().on_white().bold());
|
||||
frame.render_widget(paragraph, areas[1]);
|
||||
|
||||
// style the whole widget instead of just the text
|
||||
let paragraph = Paragraph::new("Hello World!").style(Style::new().red().on_white());
|
||||
frame.render_widget(paragraph, areas[2]);
|
||||
|
||||
// use the simpler short-hand syntax
|
||||
let paragraph = Paragraph::new("Hello World!").blue().on_yellow();
|
||||
frame.render_widget(paragraph, areas[3]);
|
||||
}
|
||||
```

## Status of this fork
|
||||
|
||||
In response to the original maintainer [**Florian Dehau**](https://github.com/fdehau)'s issue
|
||||
regarding the [future of `tui-rs`](https://github.com/fdehau/tui-rs/issues/654), several members of
|
||||
the community forked the project and created this crate. We look forward to continuing the work
|
||||
started by Florian 🚀
|
||||
|
||||
In order to organize ourselves, we currently use a [Discord server](https://discord.gg/pMCEU9hNEj),
|
||||
feel free to join and come chat! There is also a [Matrix](https://matrix.org/) bridge available at
|
||||
[#ratatui:matrix.org](https://matrix.to/#/#ratatui:matrix.org).
|
||||
|
||||
While we do utilize Discord for coordinating, it's not essential for contributing. We have recently
|
||||
launched the [Ratatui Forum][Forum], and our primary open-source workflow is centered around GitHub.
|
||||
For bugs and features, we rely on GitHub. Please [Report a bug], [Request a Feature] or [Create a
|
||||
Pull Request].
|
||||
|
||||
Please make sure you read the updated [contributing](./CONTRIBUTING.md) guidelines, especially if
|
||||
you are interested in working on a PR or issue opened in the previous repository.
|
||||
|
||||
## Widgets
|
||||
|
||||
### Built in
|
||||
|
||||
The library comes with the following
|
||||
[widgets](https://docs.rs/ratatui/latest/ratatui/widgets/index.html):
|
||||
|
||||
- [BarChart](https://docs.rs/ratatui/latest/ratatui/widgets/struct.BarChart.html)
|
||||
- [Block](https://docs.rs/ratatui/latest/ratatui/widgets/block/struct.Block.html)
|
||||
- [Calendar](https://docs.rs/ratatui/latest/ratatui/widgets/calendar/index.html)
|
||||
- [Canvas](https://docs.rs/ratatui/latest/ratatui/widgets/canvas/struct.Canvas.html) which allows
|
||||
rendering [points, lines, shapes and a world
|
||||
map](https://docs.rs/ratatui/latest/ratatui/widgets/canvas/index.html)
|
||||
- [Chart](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Chart.html)
|
||||
- [Clear](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Clear.html)
|
||||
- [Gauge](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Gauge.html)
|
||||
- [List](https://docs.rs/ratatui/latest/ratatui/widgets/struct.List.html)
|
||||
- [Paragraph](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Paragraph.html)
|
||||
- [Scrollbar](https://docs.rs/ratatui/latest/ratatui/widgets/scrollbar/struct.Scrollbar.html)
|
||||
- [Sparkline](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Sparkline.html)
|
||||
- [Table](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Table.html)
|
||||
- [Tabs](https://docs.rs/ratatui/latest/ratatui/widgets/struct.Tabs.html)
|
||||
|
||||
Each widget has an associated example which can be found in the [Examples] folder. Run each example
|
||||
with cargo (e.g. to run the gauge example `cargo run --example gauge`), and quit by pressing `q`.
|
||||
|
||||
You can also run all examples by running `cargo make run-examples` (requires `cargo-make` that can
|
||||
be installed with `cargo install cargo-make`).

## Acknowledgements
|
||||
|
||||
Ratatui was forked from the [tui-rs] crate in 2023 in order to continue its development. None of
|
||||
this could be possible without [Florian Dehau] who originally created [tui-rs] which inspired many
|
||||
Rust TUIs.
|
||||
|
||||
Special thanks to [Pavel Fomchenkov] for his work in designing an awesome logo for the Ratatui
|
||||
project and organization.

## Design choices
|
||||
## Demo
|
||||
|
||||
The examples contain some opinionated choices in order to make it easier for newer rustaceans to
|
||||
easily be productive in creating applications:
|
||||
This is the original demo example from the main README. It is available for each of the backends.
|
||||
[Source](./apps/demo/).
|
||||
|
||||
- Each example has an App struct, with methods that implement a main loop, handle events and drawing
|
||||
the UI.
|
||||
- We use color_eyre for handling errors and panics. See [How to use color-eyre with Ratatui] on the
|
||||
website for more information about this.
|
||||
- Common code is not extracted into a separate file. This makes each example self-contained and easy
|
||||
to read as a whole.
|
||||
|
||||
Not every example has been updated with all these points in mind yet, however over time they will
|
||||
be. None of the above choices are strictly necessary for Ratatui apps, but these choices make
|
||||
examples easier to run, maintain and explain. These choices are designed to help newer users fall
|
||||
into the pit of success when incorporating example code into their own apps. We may also eventually
|
||||
move some of these design choices into the core of Ratatui to simplify apps.

## How to update these examples
|
||||
|
||||
These gifs were created using [VHS](https://github.com/charmbracelet/vhs). Each example has a
|
||||
corresponding `.tape` file that holds instructions for how to generate the images. Note that the
|
||||
images themselves are stored in a separate `images` git branch to avoid bloating the main
|
||||
repository.
|
||||
|
||||
<!--
|
||||
|
||||
Links to images to make them easier to update in bulk. Use the following script to update and upload
|
||||
the examples to the images branch. (Requires push access to the branch).
|
||||
|
||||
```shell
|
||||
examples/vhs/generate.bash

```shell
|
||||
cargo run -p demo
|
||||
```

# Input Form example
|
||||
|
||||
This example demonstrates how to handle input across several form fields (2 strings and an number).
|
||||
It uses an enum to track the focused field, and sends keyboard events to one which is current.
|
||||
|
||||
Run this example with:
|
||||
|
||||
```shell
|
||||
cargo run -p input-form
|
||||
```
|
||||
|
||||
This example does not handle things like cursor movement within the line (just keys and backspace).
|
||||
Most apps would benefit from using the following crates for text input rather than directly using
|
||||
strings:
|
||||
|
||||
- [`tui-input`](https://crates.io/crates/tui-input)
|
||||
- [`tui-prompts`](https://crates.io/crates/tui-prompts)
|
||||
- [`tui-textarea`](https://crates.io/crates/tui-textarea)
|
||||
- [`rat-salsa`](https://crates.io/crates/rat-salsa)
|
||||
|
||||
Some more ideas for handling focus can be found in:
|
||||
|
||||
- [`focusable`](https://crates.io/crates/focusable) (see also [Ratatui forum
|
||||
post](https://forum.ratatui.rs/t/focusable-crate-manage-focus-state-for-your-widgets/73))
|
||||
- [`rat-focus`](https://crates.io/crates/rat-focus)
|
||||
- A useful [`Bevy` discssion](https://github.com/bevyengine/bevy/discussions/15374) about focus
|
||||
more generally.

//! A Ratatui example that demonstrates how to handle input form focus
|

//!
|

//! This example demonstrates how to handle cursor and input focus between multiple fields in a
|

//! form. You can navigate between fields using the Tab key.
|
||||
//!
|
||||
//! This does not handle cursor movement etc. This is just a simple example. In a real application,

//! How to use a panic hook to reset the terminal before printing the panic to
|
||||
//! the terminal.
|
||||
//!
|
||||
//! When exiting normally or when handling `Result::Err`, we can reset the
|
||||
//! terminal manually at the end of `main` just before we print the error.
|
||||
//!
|
||||
//! Because a panic interrupts the normal control flow, manually resetting the
|
||||
//! terminal at the end of `main` won't do us any good. Instead, we need to
|
||||
//! make sure to set up a panic hook that first resets the terminal before
|
||||
//! handling the panic. This both reuses the standard panic hook to ensure a
|
||||
//! consistent panic handling UX and properly resets the terminal to not
|
||||
//! distort the output.
|
||||
//!
|
||||
//! That's why this example is set up to show both situations, with and without
|
||||
//! the chained panic hook, to see the difference.

|

|
||||
// A simple example demonstrating how to handle user input. This is a bit out of the scope of
|
||||
// the library as it does not provide any input handling out of the box. However, it may helps
|
||||
// some to get started.
|
||||
//
|
||||
// This is a very simple example:
|
||||
// * An input box always focused. Every character you type is registered here.
|
||||
// * An entered character is inserted at the cursor position.
|
||||
// * Pressing Backspace erases the left character before the cursor position
|
||||
// * Pressing Enter pushes the current input in the history of previous messages. **Note: ** as
|
||||
// this is a relatively simple example unicode characters are unsupported and their use will
|
||||
// result in undefined behaviour.

||||

|
||||
|
||||
**ratatui-core** is the core library of the [ratatui] project,
|
||||
providing the essential building blocks for creating rich terminal user interfaces in Rust.
|
||||
|
||||
[ratatui]: https://github.com/ratatui/ratatui
|
||||
|
||||
### Why `ratatui-core`?
|
||||
|
||||
The `ratatui-core` crate is split from the main [`ratatui`](https://crates.io/crates/ratatui) crate
|
||||
to offer better stability for widget library authors. Widget libraries should generally depend
|
||||
on `ratatui-core`, benefiting from a stable API and reducing the need for frequent updates.
|
||||
|
||||
Applications, on the other hand, should depend on the main `ratatui` crate, which includes
|
||||
built-in widgets and additional features.
|
||||
|
||||
## Installation
|
||||
|
||||
Add `ratatui-core` to your `Cargo.toml`:
|
||||
|
||||
```shell
|
||||
cargo add ratatui-core
|
||||
```
|
||||

||||
