Among Ruby Facets most common additions were an assortment of Hash-like classes. To better support this collection of libraries it was deemed prudent to create a new project specifically for them. Hence the Facets Hashery.

Included in this collection are the widely used OrderedHash, the related but more featured Dictionary class, a number of open classes similar to the standard OpenStruct, some variations of the standard Hash class and a few other yummy morsels.

For instruction on usage, please see the individual library files included in this collection and read the demo documents which give examples of almost all features.

Hashery adds four core extensions of Ruby's Hash class: #retrieve, #rekey, #rekey! and Hash.create. The first is simply an alias for #[]. The later two have proven too useful over the years to omit. And the last is a convenience class method for populating a new hash with another hash upon initialization. All of these are sorely missing for Ruby itself, which is why they are provided here.

To install with RubyGems simply open a console and type:

$ sudo gem install hashery

Or add it as a dependency to your project's Gemfile:

gem "hashery"

Tarball packages are available for manual site installations via Ruby Setup.

Developers who have contributed code to the project include:

• Kirk Haines
• Joshua Hull
• Robert Klemme
• Jan Molic
• George Moschovitis
• Jeena Paradies
• Erik Veenstra

Don't be a lump on a log. See an issue? Have a suggestion? Want to help? Well git in there!

The project is hosted on Github so the easiest means of communication is via the Issues page. For more direct communication you can try the #rubyworks IRC channel on irc.freenode.net.

Hashery uses QED and Lemon test frameworks. The QED framework to create well tested high-level documentation. Run the QED specs via:

$ qed -Ilib demo/

Lemon is used to create low-level unit tests. Run these via the Rubytest:

$ rubytest -Ilib -Itest test/

Hashery's repository is hosted on GitHub. If you'd like to offer up a fix or feature, fork the repo and submit a pull request (preferably in a topic branch). I assume you have heard all the talk about proper practices, so I won't bug you with it yet again.

Yes, we FOSS programmers need to eat too! ;-) No seriously, any help you can offer goes a long way toward continued development of Rubyworks projects, including Hashery. Hop over to our Gittips page, or see the upper right-hand corner on the Rubyworks homepage. Thanks!
