//! This is my first crate. Its task is to facilitate the programmer's work by allowing the use of the well-known function "input()".
//!
//! This works the same way as in python, only you need to write '!', since this is a macro: "input!()" or "input!("Enter your name: ")".

/// Outputs (or not) text and awaiting input.

//use std::io::{stdin, self, Write};

/// Outputs (or not) text and awaiting input.
#[macro_export]
macro_rules! input {
    () => {{
        use std::io::{stdin, self, Write};

        let mut buf = String::new();
        stdin().read_line(&mut buf).unwrap();
        buf
    }};

    ($arg:tt) => {{
        use std::io::{stdin, self, Write};

        let text: &str = $arg;

        print!("{}", text);
        io::stdout().flush().expect("flush error");

        let mut buf = String::new();
        stdin().read_line(&mut buf).expect("read line error");
        buf
    }};
}
