Binary Operation in Ruby

[Vu Nang Luc]

Dear all,

I've tried Ruby for some time. The language is pretty nice but now I
need some operations with binary data. I tried but I still can not
find out what to use?

What I really need is:
a = 3;
b = ~a;
c = a >>; ......
and some some class to handle an array of bytes.

I think the ability to manage binary data is vital for any languge,
can you tell me which functions to use?

Sincerely,

VN Luc

In Ruby we use the String class to hold bytes. Search this group's
archives for "binary file". Check out the Array#pack and String#unpack
methods.

Thanks, that's quite useful.
