Hi all, This is my first post here, so don't dish out the loser points to me so heartily. I have only recently gotten into Ruby, and I was writing my own methods that I might use in a couple future programs (they were YAML things, like open and closing a file, and reading a file). I saved it as yaml.rb . However, when I require it ( require 'yaml.rb') and then try to call a method I had defined in yaml.rb, I get an error saying that the method had not been defined yet: test.rb:8: undefined method `yaml_save' for main:Object (NoMethodError) yaml_save was the method I had tried to use. Any thoughts? Suggestions? Flames? Part II The missing command Today I was in the car and was coding on my dad's laptop (Windows XP), and I was writing a shuffling algorithm. I had used the .pop command in it once, and it worked. But then all of a sudden Ruby was saying that there was no command 'pop'. The syntax I had used it in was like so: b = some_array.pop Once again, any thoughts? Suggestions? Flames? --------------------------------------------| If you're not living on the edge, then you're just wasting space.
