======= plissken

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

Plissken to the rescue.

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

Usage

gem 'plissken'
my_hash = {"firstKey" => 1, "fooBars" => [{"bazBaz" => "value"}, {"blahBlah" => "value"}]}
snaked_hash = my_hash.to_snake_keys
# => {"first_key" => 1, "foo_bars" => [{"baz_baz" => "value"}, {"blah_blah" => "value"}]}

Plissken works on either string keys or symbolized keys. It has no dependencies, as it has its own underscore 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 Snake Plissken in the seminal film Escape from New York, the plissken gem is non-destructive. There is no Hash#to_snake_keys! form.

Going the other way

If you've already got snake_case and need to CamelCase it, you are encouraged to try the Awrence gem.

Contributing to plissken

• 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.
