Ruby: module problem

cat module1.rb :

#!/home/user1/.rvm/rubies/ruby-1.9.2-p180/bin/ruby

Module module1

    def add(a,b)
        return a+b
    end

    def subtract(a,b)
        return a-b
    end

end


temp = "nothing"
temp.extend module1
temp.add(5,2)

ruby module1.rb =>

module1.rb:13: syntax error, unexpected keyword_end, expecting $end

Can anyone fix it?

module keyword is case-sensitive, and, as Ray said, module must be a constant (constant name in Ruby starts with uppercase letter). This works:

module Module1

    def add(a,b)
        return a+b
    end

    def subtract(a,b)
        return a-b
    end

end


temp = "nothing"
temp.extend Module1
temp.add(5,2)

You need a lowercase m to start it all off.

Oh and the module name should be a constant....

Start with

module Module1
