we are to assert whether the associated tty is running in canonical mode, as this will determine the behaviour of read applied to the standard input

in canonical mode, read should yield whole lines at once, and will hang until it is able to supply all n requested bytes ; in such a mode, interrupts take the form of signals, and the read call may be interrupted by a signal handler

in non canonical mode,
by default, min = 1 and time = 0

if isatty, we should get our input from readline to enable history and signal handling
otherwise, we are sourcing a file into the env, and we should rely on gnl
