it seems my previous post didn’t get through for some reason, so sorry
if this is duplicated.
has anyone done something like this?
class NilClass
def empty?; true; end
def strip; nil; end
def ; nil; end
end
so you can do this without throwing exception
if !params[:s].empty?
if !params[:s][:e].strip.empty?
as opposed to:
if params[:s] && !params[:s].empty?
if params[:s] && params[:s][:e] && !params[:s][:e].strip.empty?
I’m just wondering is there negative effects of doing this? if not
then shouldn’t we be doing this. it makes your code look a lot nicer
doesn’t it?
