Not sure what your problem is as you didn't paste sample code, but this
should work as you expect:

puts "Please enter something: "
a = gets.chomp
puts "You entered: #{a}"

Listeners for what? There is a generic Observer/Observable pattern (see
http://www.ruby-doc.org/corelib/files/observer_rb.html), and there are
some hooks into the system (e.g.
http://phrogz.net/ProgrammingRuby/ref_c_class.html#Class.inherited).
What are you trying to listen to?
