Usage

Add this to your Cargo.toml:

[dependencies]
smurf = "0.2"

and this to your crate root:

extern crate smurf;

Example

use smurf;
use std::io::Write;

fn main() {
	print!("What is your name? ");
	std::io::stdout().flush().unwrap();
	let user_name = input!(String);
	print!("What is your age? ");
	std::io::stdout().flush().unwrap();
	let user_age = input!(u8);
	let shell_output = shell!("echo Hello {} of age {}", user_name, user_age); // Returns ShellResult {code: i32, stdout: String, stderr: String}
	println!("Shell output: {}", shell_output.stdout);
	println!("Shell stderr: {}", shell_output.stderr);
	println!("Shell exit code: {}", shell_output.code);
}
