shell-words

Process command line according to parsing rules of Unix shell.

Usage

Add this to Cargo.toml: toml [dependencies] shell-words = "1.0.0"

Add this to your crate: rust extern crate shell_words;

Examples

Split

Compiling C source code into an executable as in default build rule found in GNU Make:

```rust extern crate shell_words;

use std::env::var; use std::process::Command;

fn main() { let cc = var("CC").unwraporelse(|| "cc".toowned());

let cflags = var("CFLAGS").unwrap_or_else(|_| String::new());
let cflags = shell_words::split(&cflags).expect("failed to parse CFLAGS");

let cppflags = var("CPPFLAGS").unwrap_or_else(|_| String::new());
let cppflags = shell_words::split(&cppflags).expect("failed to parse CPPFLAGS");

Command::new(cc)
    .args(cflags)
    .args(cppflags)
    .args(&["-c", "a.c", "-o", "a.out"])
    .spawn()
    .expect("failed to start subprocess")
    .wait()
    .expect("failed to wait for subprocess");

} ```

Join

Logging executed commands in format that can be readily copied and pasted to a shell:

```rust extern crate shell_words;

fn main() { let argv = &["python", "-c", "print('Hello world!')"];

println!("Executing: {}", shell_words::join(argv));

std::process::Command::new(&argv[0])
    .args(&argv[1..])
    .spawn()
    .expect("failed to start subprocess")
    .wait()
    .expect("failed to wait for subprocess");

} ```
