Documentation

Allows for reverse merging where its the keys in the calling hash that wins over those in the other_hash. This is particularly useful for initializing an incoming option hash with default values:

def setup(options = {})
  options.reverse_merge! :size => 25, :velocity => 10
end

The default :size and :velocity is only set if the options passed in doesn‘t already have those keys set.

reverse_merge(other_hash)

Performs the opposite of merge, with the keys and values from the first hash taking precedence over the second.
