gets() should work, but you should use $stdin.gets() instead:

bash$ ruby -v
ruby 1.6.8 (2002-12-24) [i686-linux]

bash$ ruby -e 'print "input: "; $stdout.flush; p gets'
input: testing
"testing\n"

bash$ ruby -e 'print "input: "; $stdout.flush; p gets' foo
input: -e:1:in `gets': No such file or directory - "foo" (Errno::ENOENT)
        from -e:1

bash$ ruby -e 'print "input: "; $stdout.flush; p $stdin.gets' foo
input: testing
"testing\n"
