Hi, I need to create binary data from Ruby to send via network some
structure like this:
- field 1: 1 bit
- field 2: 1 bit
- field 3: 1 bit
- field 4: 1 bit
- field 5: 4 bits
- field 6: 1 bit
- field 7: 7 bits
- field 8: 16 bits
(and so on)
Which is the proer way to generate such binary data from Ruby?
Thanks a lot.

There are various ways. Off the top of my head:
1. Use Array#pack with 'B' or 'b'.
2. Use an integer to construct the whole bit data and convert it via
"%032b" % i.
Kind regards

Thanks, using Array#pack is the way I've remembered (After reading your mail) 
Thanks a lot.
