# SmURF > SMall Useful Rust Functions ## Components ### IO - macros input!(T) and input_vec!(T), that could be used to simplify stdin process - read_file_to_str() basically reads file to string (yes.) ### Shell - macros shell!() ## Usage Add this to your `Cargo.toml`: ```toml [dependencies] smurf = "0.2" ``` and this to your crate root: ```rust extern crate smurf; ``` ## Example ```rust 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); } ``` ## License [MIT](LICENSE-MIT)
