With or without arguments - how?


#1

I’ve used methods before that work with or without arguments. I’ve tried
to figure it out but can’t get to the bottom of it. Could someone give
me a hint how you would go about creating a method that works for either
of these cases?

mymethod(x, y)
x + y
end

Then somehow get this to work without the (x, y) arguments…? What I
want is to have a method that can do something on default if no
arguments are spec’d or I can refine what it does by adding arguments.

What methods? Have you looked at the source for those methods? Have
you read Programming Ruby? What about this section (http://www.ruby-
doc.org/docs/ProgrammingRuby/html/tut_methods.html)?

HTH,

Try this:
my_method(x = 1, y = 1)
x + y
end

OK, sorry this was a dumb question. I missed default values.

Thank you.

… and probably the splash operator as well which can be used to
similar purpose.

Kind regards
