Cross-platform Terminal Manipulation Library

Have you ever been disappointed when a terminal library for the Rust language was only written for UNIX systems? Crossterm provides clearing, input handling, styling, cursor movement and terminal actions for both Windows and UNIX systems.

Crossterm aims to be simple and easy to call in code. Through the simplicity of Crossterm, you do not have to worry about the platform you are working with.

This crate supports all UNIX and Windows terminals down to Windows 7 (not all terminals are tested, see Tested Terminals for more info).

Note on Migration

You may have noticed that Crossterm has been changing very quickly with the latest versions. We have done a lot of API-breaking changes by renaming functions, commands, changing the exports, improving the encapsulation, etc.. However, all of this happens to improve the library and make it better and ready for a possible 1.0 release. We want to stick to the Command API and remove all other ways to use crossterm. Try to use this API and change your code accordingly. This way you will survive or overcome major migration problems ;).

We hope you can understand this, feel free to ask around in discord if you have questions. For up-to-date examples, have a look at the examples repository. Sorry for the inconvenience.

Getting Started

[dependencies]
crossterm = "0.13"
use std::io::{stdout, Write};

use crossterm::{execute, ExecutableCommand, style::{Attribute, Color, SetForegroundColor, SetBackgroundColor, ResetColor}, Output, Result};

fn main() -> Result<()> {
    // using the macro
    execute!(
        stdout(),
        SetForegroundColor(Color::Blue),
        SetBackgroundColor(Color::Red),
        Output("Styled text here."),
        ResetColor
    )?;

    // or using functions
    stdout()
        .execute(SetForegroundColor(Color::Blue))?
        .execute(SetBackgroundColor(Color::Red))?
        .execute(Output("Styled text here."))?
        .execute(ResetColor)?;

    Ok(())
}
