Question

I have a function where I get input from a user

def get_single_argument(argument,name)

    begin
        puts "Type #{name}: "
        argument = STDIN.gets.chomp
        puts "#{name} --> #{argument} OK??"

        happy = STDIN.gets.downcase.chomp

    end until (happy.strip[0,1].to_s =='y' )
end

but when I call this function where the argument is a global variable the global variable is not updated. How can I assign a value to a global variable which name is passed as a function argument? $web_url is ” – empty string.

       $web_url =''
       puts "url je:#{$web_url}"

       get_single_argument($web_url,"web url")
       puts "url je:#{$web_url}"

You can use String.replace inside your method. Instead of

argument = STDIN.gets.chomp

you can write

argument.replace STDIN.gets.chomp
