forkprocess

Documentation

Overview

Package forkprocess starts a process which runs in the background. In Granted we use it to launch a browser when the user requests a web console. Previously, we used exec.Command from Go's stdlib for this, but is susceptible to being closed when the user pressed CTRL+C in their terminal.

Thanks to @patricksanders for the advice here. The github.com/ik5/fork_process package is also a good reference we'd like to acknowledge.
