This means that at each new frame you should build all widgets that are -supposed to be part of the UI. While providing a great flexibility for rich and -interactive UI, this may introduce overhead for highly dynamic content. So, the -implementation try to minimize the number of ansi escapes sequences generated to -draw the updated UI. In practice, given the speed of `Rust` the overhead rather -comes from the terminal emulator than the library itself. - -Moreover, the library does not provide any input handling nor any event system and -you may rely on the previously cited libraries to achieve such features. - -## Rust version requirements - -Since version 0.17.0, `ratatui` requires **rustc version 1.59.0 or greater**. - -# Documentation - -The documentation can be found on [docs.rs.](https://docs.rs/ratatui) - -# Demo - -The demo shown in the gif can be run with all available backends. - -``` -# crossterm -cargo run --example demo --release -- --tick-rate 200 -# termion -cargo run --example demo --no-default-features --features=termion --release -- --tick-rate 200 -``` - -where `tick-rate` is the UI refresh rate in ms. - -The UI code is in [examples/demo/ui.rs](https://github.com/tui-rs-revival/ratatui/blob/main/examples/demo/ui.rs) while the -application state is in [examples/demo/app.rs](https://github.com/tui-rs-revival/ratatui/blob/main/examples/demo/app.rs). - -If the user interface contains glyphs that are not displayed correctly by your terminal, you may want to run -the demo without those symbols: - -``` -cargo run --example demo --release -- --tick-rate 200 --enhanced-graphics false -``` - -# Widgets - -## Built in - -The library comes with the following list of widgets: - -- [Block](https://github.com/tui-rs-revival/ratatui/blob/main/examples/block.rs) -- [Gauge](https://github.com/tui-rs-revival/ratatui/blob/main/examples/gauge.rs) -- [Sparkline](https://github.com/tui-rs-revival/ratatui/blob/main/examples/sparkline.rs) -- [Chart](https://github.com/tui-rs-revival/ratatui/blob/main/examples/chart.rs) -- [BarChart](https://github.com/tui-rs-revival/ratatui/blob/main/examples/barchart.rs) -- [List](https://github.com/tui-rs-revival/ratatui/blob/main/examples/list.rs) -- [Table](https://github.com/tui-rs-revival/ratatui/blob/main/examples/table.rs) -- [Paragraph](https://github.com/tui-rs-revival/ratatui/blob/main/examples/paragraph.rs) -- [Canvas (with line, point cloud, map)](https://github.com/tui-rs-revival/ratatui/blob/main/examples/canvas.rs) -- [Tabs](https://github.com/tui-rs-revival/ratatui/blob/main/examples/tabs.rs) - -Click on each item to see the source of the example.

[ratatui](https://github.com/tui-rs-revival/ratatui) is a library used to build rich -//! terminal users interfaces and dashboards. -//! -//! ![](https://raw.githubusercontent.com/tui-rs-revival/ratatui/master/assets/demo.gif) -//! -//! # Get started -//! -//! ## Adding `ratatui` as a dependency -//! -//! Add the following to your `Cargo.toml`: -//! ```toml -//! [dependencies] -//! crossterm = "0.26" -//! ratatui = "0.20" -//! ``` -//! -//! The crate is using the `crossterm` backend by default that works on most platforms. But if for -//! example you want to use the `termion` backend instead. This can be done by changing your -//! dependencies specification to the following: -//! -//! ```toml -//! [dependencies] -//! termion = "1.5" -//! ratatui = { version = "0.20", default-features = false, features = ['termion'] } -//! -//! ``` -//! -//! The same logic applies for all other available backends. -//! -//! ## Creating a `Terminal` -//! -//! Every application using `ratatui` should start by instantiating a `Terminal`. It is a light -//! abstraction over available backends that provides basic functionalities such as clearing the -//! screen, hiding the cursor, etc. -//! -//! ```rust,no_run -//! use std::io; -//! use ratatui::{backend::CrosstermBackend, Terminal}; -//! -//! fn main() -> Result<(), io::Error> { -//! let stdout = io::stdout(); -//! let backend = CrosstermBackend::new(stdout); -//! let mut terminal = Terminal::new(backend)?; -//! Ok(()) -//! } -//! ``` -//! -//! If you had previously chosen `termion` as a backend, the terminal can be created in a similar -//! way: -//! -//! ```rust,ignore -//! use std::io; -//! use ratatui::{backend::TermionBackend, Terminal}; -//! use termion::raw::IntoRawMode; -//! -//! fn main() -> Result<(), io::Error> { -//! let stdout = io::stdout().into_raw_mode()?; -//! let backend = TermionBackend::new(stdout); -//! let mut terminal = Terminal::new(backend)?; -//! Ok(()) -//! } -//! ``` -//! -//! You may also refer to the examples to find out how to create a `Terminal` for each available -//! backend. -//! -//! ## Building a User Interface (UI) -//! -//! Every component of your interface will be implementing the `Widget` trait. The library comes -//! with a predefined set of widgets that should meet most of your use cases. You are also free to -//! implement your own. -//! -//! Each widget follows a builder pattern API providing a default configuration along with methods -//! to customize them. The widget is then rendered using [`Frame::render_widget`] which takes -//! your widget instance and an area to draw to. -//! -//! The following example renders a block of the size of the terminal: -//! -//! ```rust,no_run -//! use std::{io, thread, time::Duration}; -//! use ratatui::{ -//! backend::CrosstermBackend, -//! widgets::{Widget, Block, Borders}, -//! layout::{Layout, Constraint, Direction}, -//! Terminal -//! }; -//! use crossterm::{ -//! event::{self, DisableMouseCapture, EnableMouseCapture, Event, KeyCode}, -//! execute, -//! terminal::{disable_raw_mode, enable_raw_mode, EnterAlternateScreen, LeaveAlternateScreen}, -//! }; -//! -//! fn main() -> Result<(), io::Error> { -//! // setup terminal -//! enable_raw_mode()?; -//! let mut stdout = io::stdout(); -//! execute!(stdout, EnterAlternateScreen, EnableMouseCapture)?; -//! let backend = CrosstermBackend::new(stdout); -//! let mut terminal = Terminal::new(backend)?; -//! -//! terminal.draw(|f| { -//! let size = f.size(); -//! let block = Block::default() -//! .title("Block") -//! .borders(Borders::ALL); -//! f.render_widget(block, size); -//! })?; -//! -//! thread::sleep(Duration::from_millis(5000)); -//! -//! // restore terminal -//! disable_raw_mode()?; -//! execute!( -//! terminal.backend_mut(), -//! LeaveAlternateScreen, -//! DisableMouseCapture -//! )?; -//! terminal.show_cursor()?; -//! -//! Ok(()) -//! } -//! ``` -//! -//! ## Layout -//! -//! The library comes with a basic yet useful layout management object called `Layout`. As you may -//! see below and in the examples, the library makes heavy use of the builder pattern to provide -//! full customization. And `Layout` is no exception: -//! -//! ```rust,no_run -//! use ratatui::{ -//! backend::Backend, -//! layout::{Constraint, Direction, Layout}, -//! widgets::{Block, Borders}, -//! Frame, -//! }; -//! fn ui(f: &mut Frame) { -//! let chunks = Layout::default() -//! .direction(Direction::Vertical) -//! .margin(1) -//! .constraints( -//! [ -//! Constraint::Percentage(10), -//! Constraint::Percentage(80), -//! Constraint::Percentage(10) -//! ].as_ref() -//! ) -//! .split(f.size()); -//! let block = Block::default() -//! .title("Block") -//! .borders(Borders::ALL); -//! f.render_widget(block, chunks[0]); -//! let block = Block::default() -//! .title("Block 2") -//! .borders(Borders::ALL); -//! f.render_widget(block, chunks[1]); -//! } -//! ``` -//! -//! This let you describe responsive terminal UI by nesting layouts. You should note that by -//! default the computed layout tries to fill the available space completely. So if for any reason -//! you might need a blank space somewhere, try to pass an additional constraint and don't use the -//! corresponding area. - -pub mod backend; -pub mod buffer; -pub mod layout; -pub mod style; -pub mod symbols; -pub mod terminal; -pub mod text; -pub mod widgets; - -pub use self::terminal::{Frame, Terminal, TerminalOptions, Viewport}; diff --git a/atuin/src/ratatui/style.rs b/atuin/src/ratatui/style.rs deleted file mode 100644 index 4d74f6f..0000000 --- a/atuin/src/ratatui/style.rs +++ /dev/null @@ -1,310 +0,0 @@ -//! `style` contains the primitives used to control how your user interface will look. - -use bitflags::bitflags; - -#[derive(Debug, Clone, Copy, PartialEq, Eq)] -#[cfg_attr(feature = "serde", derive(serde::Serialize, serde::Deserialize))] -pub enum Color { - Reset, - Black, - Red, - Green, - Yellow, - Blue, - Magenta, - Cyan, - Gray, - DarkGray, - LightRed, - LightGreen, - LightYellow, - LightBlue, - LightMagenta, - LightCyan, - White, - Rgb(u8, u8, u8), - Indexed(u8), -} - -bitflags! { - /// Modifier changes the way a piece of text is displayed. - /// - /// They are bitflags so they can easily be composed. - /// - /// ## Examples - /// - /// ```rust - /// # use ratatui::style::Modifier; - /// - /// let m = Modifier::BOLD | Modifier::ITALIC; - /// ``` - #[cfg_attr(feature = "serde", derive(serde::Serialize, serde::Deserialize))] - pub struct Modifier: u16 { - const BOLD = 0b0000_0000_0001; - const DIM = 0b0000_0000_0010; - const ITALIC = 0b0000_0000_0100; - const UNDERLINED = 0b0000_0000_1000; - const SLOW_BLINK = 0b0000_0001_0000; - const RAPID_BLINK = 0b0000_0010_0000; - const REVERSED = 0b0000_0100_0000; - const HIDDEN = 0b0000_1000_0000; - const CROSSED_OUT = 0b0001_0000_0000; - } -} - -/// Style let you control the main characteristics of the displayed elements. -/// -/// ```rust -/// # use ratatui::style::{Color, Modifier, Style}; -/// Style::default() -/// .fg(Color::Black) -/// .bg(Color::Green) -/// .add_modifier(Modifier::ITALIC | Modifier::BOLD); -/// ``` -/// -/// It represents an incremental change.
