Snake Case Hash (was: Rash)¶ ↑

If you are reading this in 2018, don’t use this gem – this is only kept around because some products from other people have it as a dependency and I have sent a pull request to them with better solutions.¶ ↑

This version of rash has been renamed snake_case_hash gem (with class Hashie::SCHash) to avoid namespace conflicts in gemspec.¶ ↑

This was needed because Hashie version 3 introduced a new class Hashie::Rash that interfered with the Hashie::Rash class that was in the Rash gem, and the maintainer of the Rash gem hasn’t updated or accepted pull requests in some time. I guess this is a fork but just to avoid problems around loading gems in .gemspec files (which unlike bundler doesn’t allow you to specify git sources.)

Snake Case Hash is an extension to Hashie ( github.com/intridea/hashie ) that was originally named Rash.

SCHash subclasses Hashie::Mash to convert all keys in the hash to underscore

The purpose of this is when working w/ Java (or any other apis) that return hashes (including nested) that have camelCased keys

You will now be able to access those keys through underscored key names (camelCase still available)

Usage¶ ↑

@rash = Hashie::SCHash.new({
  "varOne" => 1,
  "two" => 2,
  :three => 3,
  :varFour => 4,
  "fiveHumpHumps" => 5,
  :nested => {
    "NestedOne" => "One",
    :two => "two",
    "nested_three" => "three"
  },
  "nestedTwo" => {
    "nested_two" => 22,
    :nestedThree => 23
  }
})

@rash.var_one                 # => 1
@rash.two                     # => 2
@rash.three                   # => 3
@rash.var_four                # => 4
@rash.five_hump_humps         # => 5
@rash.nested.nested_one       # => "One"
@rash.nested.two              # => "two"
@rash.nested.nested_three     # => "three"
@rash.nested_two.nested_two   # => 22
@rash.nested_two.nested_three # => 23

Note on Patches/Pull Requests¶ ↑

• Fork the project.

• Make your feature addition or bug fix.

• Add tests for it. This is important so I don’t break it in a future version unintentionally.

• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)

• Send me a pull request. Bonus points for topic branches.
