The script has this chunk of code in it: # Get the XML file puts 'Opening the file' open("messages.xml", "r") do |f| puts 'File is opened' theXML = Hpricot::XML(f) puts 'Tryin...

If I Ctrl+C to cancel it, the output says: C:/Ruby/lib/ruby/gems/1.8/gems/watir-1.6.5/lib/watir/ie-class.rb:506:in `wait': Interrupt from C:/Ruby/lib/...
Hi, I've never seen the point of installing the ri and rdoc for gems and my .gemrc file has --no-ri and --no-rdoc set. Since every gem includes ri and rdoc info, I just wondered if I'm missing something? Is there any advantage to installing the ri and rdoc for a gem? Thanks Chris Summary If you don't install the ri and rdoc, you don...

obj = SomeObject.new def obj.new_method "do some things" end puts obj.new_method > "do some things" This works ok. However, I need to do same thing inside an existing method: def some_random_method def obj.new_method "do some things" end end Works ok as well, but having a method inside a method looks pretty horrible.

I'm trying to return an array of counted values for consecutive date ranges (that will vary in distance), so that I have something like the following: counted_values = [2,0,4,5,6,0,0,4,2] So far I've written something that works but makes me shudder slightly, as I'm sure there's a more Rubyist/Rails way of doing it. Current code: ...

Hi all, So I'm trying to figure out a way of stubbing a controller method in rspec for a Sinatra app. The main reason for this is to test the logical flow of the application and to make sure it calls the necessary functions when certain conditions are met. So, in essence, I want to be able to do something like controller.should_receive...
Can anyone provide some clues as to why these two pieces of code are not equivalent? My only thought is that the .open in the latter code portion is not in a block and the file handle is left open. File.open(file) do |io| io.each_line do |line| body_string << line end end and this one File.open(file).each_line {|line| body_s...
