Hi. First post in this group and I hope someone can help.
I am trying to teach myself Ruby with a long-term goal of doing some
web development using Ruby on Rails.
Note: version
C:\rails\hello>ruby -v
ruby 1.9.2p290 (2011-07-09) [i386-mingw32]
I have been going through Jeremy McAnally''s book "Mr. Neighborly’s
Humble Little Ruby Book" and there is a section in chapter 5 where he
explains how to connect a socket using the lines:
require "socket"
myserver = TCPserver.new(''localhost'', 0)
When I try this I get the error:
C:\rails\hello>ruby server.rb
server.rb:2:in `<main>'': uninitialized constant Object::TCPserver
(NameError)
So I look in the socket.rb file and sure enough there is no TCPserver
class although all of the documentation I find online says there
should be. I even went to http://rubyinstaller.org/downloads/ to get
ruby and install again and still no luck.
Is this a deprecated class? Is there some other way to make a socket
connection? Is there somewhere that I can get the version of socket
that contains this class?
Thank you.

Ruby is case sensitive. Try with TCPServer.. -Jazmin On Thu, Sep 8, 2011 at 1:48 PM, zxcv <zxcvnosend-/E1597aS9LQAvxtiuMwx3w@public.gmane.org> wrote:> Hi.

Spelled it correctly in the title. A good hint as to what was wrong: Object::TCPserver (NameError) Sometimes, if you know your code is right, but it still won''t work, delete the offending line and retype it. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
