# SmURF
> SMall Useful Rust Functions
## Components
### IO
- macros input!(T) and input_vec!(T), that could be used to simplify stdin process
- read_file_str() basically reads file to string (yes.)
- read_file_bytes() see read_file_str()
### Shell
- macros shell!()
## Usage
Add this to your `Cargo.toml`:
```toml
[dependencies]
smurf = "0.3"
```
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);
}
```
