I thought that (in a while...do loop)
gets.chomp != ''
might match a carriage return from a terminal. It doesn't. What am I not understanding? Thank you.
String#chomp removes carriage returns from the string it is being called on.
If you remove chomp
it should give you the expected output. See below:
2.1.2 :001 > def foo
2.1.2 :002?> while true do
2.1.2 :003 > puts gets != ''
2.1.2 :004?> end
2.1.2 :005?> end
=> :foo
2.1.2 :006 > foo
a
true
b
true
c
true
1
true
2
true
# about to press enter
true
true
Hope this helps
