I am new to Ruby. Is there any way to include the module in normal ruby file? For an example, Test.rb Class Test.rb ........ end testing.rb object = Test.new # It tells error.

Note that Test.rb should say 'class' not 'Class' Also, it doesn't really matter what filename you use, but there is a common convention that the name of the source file is the lowercased, underscored version of the class name. So conventionally you would call your file 'test.rb'. For a file containing class MyTestClass you would call it my_test_class.rb HTH, Brian.

Add: require 'Test' to testing.rb before calling Test.new (assuming that Test.rb and testing.rb are in the same directory and that you run ruby from that directory). Also, notice that: 1) you should write class Test, not class Test.rb (note the downcase c in class and the absence of the .rb from Test). Class names have nothing in common with file names 2) file names are (I think) case senstive in ruby, so if you call your file Test.rb you'll need to require 'Test'; if you call it test.rb you'll need to require 'test'. If you're on windows, which is not a case sensitive OS, you may be used to a different behaviour (actually, I'm not completely sure of how this behaves on windows, as I've never used ruby on it) 3) modules in ruby are something entirely different (see the documentation for the Module class either at http://www.ruby-doc.org/core/ or using ri: ri Module. For more information you can look at the documentation for the require method of module Kernel, either at http://www.ruby-doc.org/core/ or using ri: ri Kernel#require. You may also find useful reading the free online version of the Pickaxe book (http://www.ruby-doc.org/docs/ProgrammingRuby/) it's a bit outdated, but it should be useful all the same. I hope this helps Stefano

Sort of similar type problem to what is already posted here. I'm two months into Ruby and I can write single file code that purely functions from the command line and separate ones that function in conjunction with SketchUp. I would like to maximize the compartmentalization of modules but am getting stuck. My understanding is that files that are called with require need to be in the path given when ruby -e 'puts $:' is typed at the command line. So, I have a driver file in the pluggins directory in SketchUp in which I require 'a_file' but I get a file not found error. Error: #<LoadError: No such file to load -- abc> C:\Program Files\Google\Google SketchUp 7\Plugins\test.rb:1:in `require' C:\Program Files\Google\Google SketchUp 7\Plugins\test.rb:1 Why isn't the driver program seeing my module file? The module file (Abc.rb) is in the C:/Ruby/lib/ruby/site_ruby directory. The driver file (test.rb) calls the module on the first line with require 'abc' which generates the error. Jessica
