Let's say I build my package using dub run from an Ubuntu terminal. How can I add sudo as the executable is being run? I tried adding preRunCommands to my dub.sdl as described in [1] but that just runs sudo and terminal throws an error.

Something like this, I guess:

import core.sys.posix.unistd: getuid;
import std.process: execv;

void main(string[] args)
{
    if (getuid() != 0) {
        execv("sudo", args);
        return 1; // failed to exec
    }

    // The rest of your code goes here
}

My solution has been slightly different. I use postBuildCommands and use dub build package:example_backend at my terminal instead of dub run package:example_backend.

subPackage {
	name "example_backend"
	sourcePaths "source/example_backend" "lib"
	importPaths "lib"
	targetName "example_backend"
	targetType "executable"
	dependency "mysql-native" version="~>2.2.2"
	postBuildCommands "sudo ./example_backend"
}

Best,
