Convert a string of text (user input) to binary

Question

I basically need to get user input:

gets.chomp("input?")

And then to convert the given input to binary.

That's the part I don't get. :(

What do you mean convert to binary? Convert to a binary int representation? Pack into some kind of byte stream? — Michael Berkowski, Jun 19 '12 at 23:19
or rather, "Hello!" would be 01001000 01100101 01101100 01101100 01101111 00100001 — Delta, Jun 19 '12 at 23:39

your two questions so far look suspiciously like school homework and should be tagged as such — DGM, Jun 20 '12 at 02:53

Try this.

a = gets.chomp
puts a.each_byte.map {|y| sprintf "%08b", y}.join " "

This is unsatisfactory: it doesn't zero pad, or space, so you get a stream of digits, but it's impossible to reassemble the original meaningfully. – Asherah Jun 20 '12 at 01:24
