Terminal Utilities

Provides a way to read passwords from a terminal. Terminal echo is disabled when reading the password.

Also provides the ability to check if a terminal is a tty or not.

This crate provides functionality similar to the python getpass and os.isatty functions.

Tested on Linux, macOS, and Windows.

Functions on windows use the windows api directly without relying on large crates like windows-sys or winapi.

Example: Get a password

use passterm::prompt_password_tty;

let pass = prompt_password_tty(Some("Password: ")).unwrap();

println!("Your password is: {}", &pass);

Example: Check if standard output has been redirected

use passterm::{isatty, Stream};

let is_tty = isatty(Stream::Stdout);
if is_tty {
    println!("We're in a terminal");
} else {
    println!("Not in a terminal. Output was redirected >.");
}
