Vari

Vari (Väri) is a Rust library for formatting strings with colors and cosmetic stuff to the terminal. Like Rich library for Python.

Installing

[dependencies]

Features

Color Anchor

fn main() {
    // [$/] is shorthand for [$reset]
    let message = vari::format("[$blue]Hello, [$green]World![$/]");
    println!("{}", message);

    // Custom RGB!
    println!("{}", vari::format("[$[114, 119, 39]]#727727![$[66, 4, 32]] Do you see it?[$/]"));

    // Style anchor!
    vprintln!("{}Bold and Italic :O{}", "[$bold][$italic]", "[$/]");
}

Macros

fn main() {
    // We are using `vformat!()` because `format!()` is from Rust and we can't replace it
    let f = vformat!("{}Hello!{}", "[$bright_magenta]", "[$/]");
    println!("{}", f);

    // Feeling lazy? there is vprint! and vprintln! macros!
    vprintln!("{}I'm feeling {}{}", "[$italic][$yellow]", "lazy" "$[/]");
}

Fun

fn main() {
    // Rainbow colors!
    println!("{}", vari::fun::rainbow("Rainbow!!!"));
}
