Struct nu_system::ForegroundProcess

pub struct ForegroundProcess { /* private fields */ }

A simple wrapper for std::process::Command

spawn behavior

Unix

When invoke spawn, current process will block SIGTSTP, SIGTTOU, SIGTTIN, SIGCHLD

spawned child process will get it’s own process group id, and it’s going to foreground(by making stdin belong’s to child’s process group).

When child is to over, unblock SIGTSTP, SIGTTOU, SIGTTIN, SIGCHLD, foreground process is back to callers’ process. It bahaves something like SignalHandler in ion(https://gitlab.redox-os.org/redox-os/ion/-/tree/master/).

Windows

It does nothing special on windows system, spawn is the same as std::process::Command::spawn
