Exposing Ancestor Public Methods/ Book Reccomendation

[Note: parts of this message were removed to make it a legal post.]

Hello,

I am trying to access some attr_accessor and public/protected methods from
an inheriting class or module.

class Foo:
def initialize(); end
def some_method():
print "Foo are you?\n"
end
end

class Bar < Foo
class << self; end
def initialize(); end
def another_method()
print "Bar am I"
end
end

If I do a Foo.public_methods, it will list some_method as one of those
methods. I am trying to get Bar.public_method to also list that inherited
method.Is this possible?
Is there also a way to force this inheritance with instance variables?
Likewise I would like to do perform the same activities on modules, and is
that possible (example below of how I am doing this)?

module Foo:
def some_method():
print "Foo are you?\n"
end
end

class Bar < Foo
class << self; end
def initialize(); end
def another_method()
print "Bar am I"
end
end

Also, is there book that speaks about the core aspects of Ruby programming,
giving detailed Networking, thread programming, etc. Basically, I am
looking for a general reference book that covers a wide range of areas in
Ruby programming, which are accompanied by examples. Additionally, the
topics do not need to cover Ruby on Rails. Thanks.

You need "The Ruby Way", Second Edition, by Hal Fulton.

now his band is very small, 1 keyboard player who sometimes plays
percussion, 1 drummer, 1 lead guitar player, 1 rhythm guitar player
who sometimes plays bass and Paul on lead vocals, bass, guitar, piano
or even mandolin. only 5 guys, and as usually, there's no back up
singers, never a female choir, all the guys in the band doing vocals,
specially the drummer.
