This gem extends the Hash class with the following methods:
map_keys
map_keys!
map_values
map_values!
The bang version of each method will modify the keys or values of the hash according to the given block. The non-bang version will return a new hash.
Add this line to your application's Gemfile:
gem 'hash_transform'
And then execute:
$ bundle
Or install it yourself as:
$ gem install hash_transform
Just require the gem directly or through Bundler, and the methods will be available.
