Ruby script

Ruby

Hi,

I wrote a ruby script but I’d like to define a method within it and
call the method from the main method. How do I do that? Do I have to
define the whole file as a module or something?
Thanks

Nope (although using modules can make your code easier to reuse and/or
combine with other code)

Simple example which I think achieves what you want:

---- a.rb ----
def say_hello
puts “Hello, world!”
end

---- b.rb ----
require ‘a’
say_hello

---- command line ----
ruby b.rb

Ruby doesn’t have a main method. Your script starts being executed at
the very top and ends at the very bottom. Everything in between is
executed line by line.

How about:

====================
def mymethod
puts “Hello from my method!”
end

mymethod

?

I realized I was having issues because I defined the method I wanted
to use after the script…obviously it should be defined before. Then
it runs just fine without having to be a module.
