I'm trying to find a way to see if a user has typed anything into the REPL
while a long-running computation takes place so that users can hit a special
key to pause their computation and inspect its intermediate state.
To get started, I wrote this snippet and tried to see if it would count input
that I typed into the REPL:
for i in 1:5
sleep(1)
println()
println(nb_available(STDIN))
end
It doesn't seem like STDIN receives the keystrokes I type while this loop is
executing.
How would one get access to those keystrokes in the current REPL? Should I be
using some kind of interrupt handling instead?
