Have you ever needed to automatically convert Rubyish snake_case to JSON-style camelBack or CamelCase hash keys?

Awrence to the rescue.

This gem recursively converts all snake_case keys in a hash structure to camelBack or CamelCase.

Usage

my_hash = {"first_key" => 1, "foo_bars" => [{"baz_baz" => "value"}, {"blah_blah" => "value"}]}
camel_hash = my_hash.to_camel_keys
# => {"firstKey" => 1, "fooBars" => [{"bazBaz" => "value"}, {"blahBlah" => "value"}]}

Awrence works on either string keys or symbolized keys. It has no dependencies, as it has its own camelize method lifted out of ActiveSupport.

Limitations

Your keys must be camelBack or CamelCase. The key "Foo Bar" will output as "foo bar".
Unlike the original T.E. Lawrence, the awrence gem is non-destructive. There is no Hash#to_camel_keys! form.

Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
Fork the project.
Start a feature/bugfix branch.
Commit and push until you are happy with your contribution.
Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
