Hi - I'm new to ruby and trying to write some classes to help me with my
work. What I'm trying to figure out is how to access the class methods
from other files. Say that my class is
Class Example
$glob_1
def method_1
#...
end
def method_2
#...
end
end
Then in another file (same dir) I'd do:
require 'example'
f = example.method_1
Is this correct?
Also, I want to test my class - where do I add the:

Did you try it?
It won't work. There are several reasons. Class methods are defined like this:
class Example
def self.method1
puts "method1"
end
def Example.method2
puts "method2"
end
class << self
def method3
puts "method3"
end
end
end
Then in your other file, the require is fine (if the file is called example.rb).
But the class methods have to be invoked on the class object, which is assigned
to the constant after the word class. So it's Example with capital E.
require 'example'
Example.method1
Also, I want to test my class - where do I add the:
if __FILE__ = $0
method_1
method_2
end
It's usually added at the end of the file, after the class is defined.
Also here you will need to call the methods as Example.method_1
Hope this helps,
Jesus.
