# Cross-platform Terminal Manipulation Library 

Crossterm is a pure-rust, terminal manipulation library that makes it possible to write cross-platform text-based interfaces (see [features](#features)). It supports all UNIX and Windows terminals down to Windows 7 (not all terminals are tested,
see [Tested Terminals](#tested-terminals) for more info).

### Tested Terminals

- Console Host
    - Windows 10 (Pro)
    - Windows 8.1 (N)

This crate supports all UNIX terminals and Windows terminals down to Windows 7; however, not all of the
terminals have been tested. If you have used this library for a terminal other than the above list without
issues, then feel free to add it to the above list - I really would appreciate it!

    style::{Color, Print, ResetColor, SetBackgroundColor, SetForegroundColor},
    ExecutableCommand, Result,
    event,
};

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