Puts gets

Ruby
1

I write this:

puts “foo”
some_var = gets

I expect the foo to show up before the gets occurs but it does not. Any
ideas?

The puts maybe buffered. Does this work as you expect:

$stdout.sync = true
puts “foo”
some_var = gets

Or you could manually flush the buffer:
puts “foo”
STDOUT.flush
some_var = gets
