# prettui
A terminal-based library to build beautiful and interactive command-line user interfaces in Rust.
## Features
* **Configurable Lists**: Customize items per row, rows per page, and cell width.
* **Arrow & Page Navigation**: Navigate lists using arrow keys, PageUp/PageDown.
* **Numeric Input**: Real-time, multi-digit numeric list input with live feedback.
* **Custom Colors**: Easily style prefixes, prompts, and output text with configurable colors.
* **Input and Output Utilities**: Flexible input prompts and styled, wrapped console output.
## Installation
Add `prettui` to your `Cargo.toml`:
```toml
[dependencies]
prettui = "0.3.1"
```
Or using command:
```
cargo add prettui
```
Then import the prelude in your code:
```rust
use prettui::prelude::*;
```
## Example
```rust
use prettui::prelude::*;
fn main() -> anyhow::Result<()> {
// Prepare a list of 100 items
let items: Vec<String> = (1..=100).map(|i| format!("Item {}", i)).collect();
// Configure the list display
let config = ListConfig::default()
.items_per_row(1)
.rows_per_page(10)
.cell_width(30)
.normal_fg(Color::DarkGrey)
.highlight_fg(Color::Green);
println!("Example of using prettui list chooser");
println!(
"Use arrows/PageUp/PageDown to navigate, type digits, Backspace to delete, Enter to confirm, Esc to cancel."
);
// Let the user choose an index or cancel
if let Some(idx) = choose_from_list(&items, &config)? {
println!("You chose: {}", items[idx]);
} else {
println!("Selection cancelled.");
}
// Prompt for user input
let ic = InputConfig {
input_text_color: Color::Blue,
..Default::default()
};
let name = read_input(&ic)?;
// Print styled output without log level
let oc = OutputConfig {
log_level: None,
..Default::default()
};
write_output(&oc, &format!("Hello, {}!", name))?;
// Print styled output with a log level tag
let oc2 = OutputConfig {
log_level: Some("DEBUG".into()),
..Default::default()
};
write_output(&oc2, "This is a debug message.")?;
Ok(())
}
```
## Modules
* **`color`**: Defines the `Color` enum and conversions to terminal color types.
* **`io::input`**: Utilities for reading user input, including configurable prompts and text wrapping.
* **`io::output`**: Functions for printing styled and wrapped text, with optional log level tags.
* **`list`**: Interactive list chooser with navigation and numeric input support.
## Prelude
For convenience, `prettui::prelude` re-exports the most commonly used types and functions:
```rust
pub use crate::color::*;
pub use crate::io::*;
pub use crate::list::*;
```
