Check if hash is nil before checking specific attribute

Question

What I'm currently doing is

"Hello" if options && options[:greet]

What I would like to do is cut that line down. If options is nil, options[:greet] obviously will be too. Does Ruby/Rails provide a method that offers this "hash checking" ability? Or perhaps there's a way of writing this more succinctly?

Answer 1

There's also one more shortcut, I tend to use it more often, when I don't have control over options variable (i.e. it may be either nil or hash):

options.to_h[:greet] # just convert it to a hash before key access

Note, that it works only starting from Ruby 2.0.
