Run cargo run --example
to try the different example available.
Basic usage

cargo run --example basic
Light and dark theme
Switching custom themes while running.
cargo run --example light_and_dark_theme
File preview
Adapt the interface depending on the selected file.
cargo run --example file_preview
Basic usage
Install the libraries in your Cargo.toml
file:
cargo add ratatui ratatui-explorer crossterm
Then inside your main.rs
file:
use std::io::{self, stdout};
use crossterm::{
event::{read, Event, KeyCode},
terminal::{disable_raw_mode, enable_raw_mode, EnterAlternateScreen, LeaveAlternateScreen},
ExecutableCommand,
};
use ratatui::prelude::*;
use ratatui_explorer::{FileExplorer, Theme};
fn main() -> io::Result<()> {
enable_raw_mode()?;
stdout().execute(EnterAlternateScreen)?;
let mut terminal = Terminal::new(CrosstermBackend::new(stdout()))?;
// Create a new file explorer with the default theme and title.
let theme = Theme::default().add_default_title();
let mut file_explorer = FileExplorer::with_theme(theme)?;
loop {
// Render the file explorer widget.
terminal.draw(|f| {
f.render_widget(&file_explorer.widget(), f.size());
})?;
// Read the next event from the terminal.
let event = read()?;
if let Event::Key(key) = event {
if key.code == KeyCode::Char('q') {
break;
}
}
// Handle the event in the file explorer.
file_explorer.handle(&event)?;
}
disable_raw_mode()?;
stdout().execute(LeaveAlternateScreen)?;
Ok(())
}
Customizing the theme
You can customize the theme of the file explorer widget by using the Theme
struct.
use ratatui::{prelude::*, widgets::*};
use ratatui_explorer::Theme;
let theme = Theme::default()
.add_default_title()
.with_title_bottom(|fe| format!("[{} files]", fe.files().len()).into())
.with_block(Block::default().borders(Borders::ALL).border_type(BorderType::Rounded))
.with_highlight_item_style(Style::default().fg(Color::Yellow).add_modifier(Modifier::BOLD))
.with_highlight_dir_style(Style::default().fg(Color::Red).add_modifier(Modifier::BOLD))
.with_highlight_symbol("> ".into());
