What's the equivalent of ruby print + $stdout.flush in elixir

I can't find how to refresh a single line of output with Elixir.

In Ruby we can do this :

n = 0
loop do
  print n
  $stdout.flush
  n += 1
end

But what should I use to do the same with Elixir ?

Use IO.write/1. There's no need to manually flush stdout as far as I can see. The following code writes 1 to 10 in a single line with a 1 second delay between each number. stdout is flushed automatically after each write.

for i <- 1..10 do
  IO.write i
  :timer.sleep(1000)
end

Output:

12345678910

(With a 1 second delay between each number.)
