run_script

Run shell scripts in rust.

Overview

This library enables to invoke shell scripts based on their content.
While std::process::Command works great to execute standalone command, you need more manual code to take a script text and execute it.
For this purpose, this library was created.

Usage

Simply include the library and invoke the run/spawn function with the script text and run options:

use run_script::ScriptOptions;

fn main() {
    let options = ScriptOptions::new();

    let args = vec![];

    // run the script and get the script execution output
    let (code, output, error) = run_script::run(
        r#"
         echo "Directory Info:"
         dir
         "#,
        &args,
        &options,
    )
    .unwrap();

    println!("Exit Code: {}", code);
    println!("Output: {}", output);
    println!("Error: {}", error);

    // run the script and get a handle to the running child process
    let child = run_script::spawn(
        r#"
         echo "Directory Info:"
         dir
         "#,
        &args,
        &options,
    )
    .unwrap();

    let spawn_output = child.wait_with_output().unwrap();

    println!("Success: {}", &spawn_output.status.success());
}

The library also provides the run_script!, spawn_script! and run_script_or_exit! macros for simpler usage.

use run_script::ScriptOptions;

fn main() {
    // simple call to run script with only the script text
    let (code, output, error) = run_script::run_script!(
        r#"
         echo "Test"
         exit 0
         "#
    )
    .unwrap();

    println!("Exit Code: {}", code);
    println!("Output: {}", output);
    println!("Error: {}", error);

    // run script invoked with the script text and options
    let options = ScriptOptions::new();
    let (code, output, error) = run_script::run_script!(
        r#"
         echo "Test"
         exit 0
         "#,
        &options
    )
    .unwrap();

    println!("Exit Code: {}", code);
    println!("Output: {}", output);
    println!("Error: {}", error);

    // run script invoked with all arguments
    let options = ScriptOptions::new();
    let (code, output, error) = run_script::run_script!(
        r#"
         echo "Test"
         exit 0
         "#,
        &vec!["ARG1".to_string(), "ARG2".to_string()],
        &options
    )
    .unwrap();

    println!("Exit Code: {}", code);
    println!("Output: {}", output);
    println!("Error: {}", error);

    // spawn_script! works the same as run_script! but returns the child process handle
    let child = run_script::spawn_script!(
        r#"
         echo "Test"
         exit 0
         "#
    )
    .unwrap();

    println!("PID: {}", child.id());
}
