Question

I’m using ruby 1.8.7. I could have sworn that I’ve written my functions at the bottom of my script before and it worked fine.

Do I have to put them at the top? It seems to be the only way they work now. Not a big deal. I just prefer to have them at the bottom so I figured I’d ask.

You can do initializing code in one or more BEGIN-blocks (inherited from Perl, which inherited them from awk).

can_i_do_this? #=>yes

BEGIN {
  def can_i_do_this?
    puts "yes"
  end
}

And for completeness, there are also END-blocks:

END {
  can_i_do_this? #=> yes
}

def can_i_do_this?
  puts "yes"
end
