Macro args 

macro_rules! args {
    ($($arg:expr),* $(,)?) => { ... };
}

Available on crate feature process only.

Create a config to add multiple args of different types when building a subprocess.

See CommandBuilder for more info on spawning child processes.

Example

use std::path::Path;
use cu::pre::*;

let path = Path::new("foo");
cu::which("ls")?.command()
   // without the macros, you can't mix `&Path` and `&str`
   .add(cu::args![path, "-a"])
   // ... more config
