easy_process

Allow running external commands and properly handle its success and failures.

Windows

This creates provides a run function that does inline parsing of literal command line strings (handling escape codes and splitting at whitespace) and checks the ExitStatus of the command. If it didn't succeed they will return a Err(...) instead of a Ok(...).

Note that the provided functions do return their own Output struct instead of std::process::Output.

Example

use easy_process;

// stdout
let output = easy_process::run(r#"sh -c 'echo "1 2 3 4"'"#)?;
assert_eq!(&output.stdout, "1 2 3 4\n");

// stderr
let output = easy_process::run(r#"sh -c 'echo "1 2 3 4" >&2'"#)?;
assert_eq!(&output.stderr, "1 2 3 4\n");

Commands on windows are also supported in the same way:

let output = easy_process::run(r#"powershell /C 'echo "1 2 3 4"'"#)?;
assert_eq!(&output.stdout, "1 2 3 4\r\n");
