[Q] How do you use Array#pack?

ruby-talk
1

I know now that I need to use Array#pack, could someone please tell me
where I can find documentation on it?

I’m not asking for one or two examples where I see it used. I actually
want to learn what this method does. Pickaxe doesn’t contain much. Is
there another resource?

In particular, I want to find a list of all the inputs that pack can take
and what they mean. What is “A3”? What is “b*”? To me they look like
random strings of characters.

I hope that someone can tell me where “The Fine Maual” is.

Most useful information contained in String#unpack description.

Hi,

I know now that I need to use Array#pack, could someone please tell me
where I can find documentation on it?

I’m not asking for one or two examples where I see it used. I actually
want to learn what this method does. Pickaxe doesn’t contain much. Is
there another resource?

I see Brian’s already replied with a link to the on-line
table of pack & unpack parameters…

I just want to mention in defense of Pickaxe, that the paper version
is excellent. It has perhaps the best index of any technical book
I own, and I’ve got bookshelves packed with the things…

Regards,

Bill

The table of template characters for Array#pack may be found
between the descriptions of Array#include? and Array#index
in Pickaxe.
