The two main helpers, Hirb::Helpers::Table and Hirb::Helpers::Tree, provide several options for generating ascii tables and trees. Using Hirb::Helpers::AutoTable, hirb has useful default views for at least ten popular database gems i.e. Rails' ActiveRecord::Base. Other than views, hirb offers a smart pager and a console menu. The smart pager only pages when the output exceeds the current screen size. The menu is used in conjunction with tables to offer two dimensional menus.

• mime-types (2.6.1)

  gem install mime-types -v "2.6.1"

  download delete

  The mime-types library provides a library and registry for information about MIME content type definitions. It can be used to determine defined filename extensions for MIME types, or to use filename extensions to look up the likely MIME type definitions. MIME content types are used in MIME-compliant communications, as in e-mail or HTTP traffic, to indicate the type of content which is transmitted. The mime-types library provides the ability for detailed information about MIME entities (provided as an enumerable collection of MIME::Type objects) to be determined and used. There are many types defined by RFCs and vendors, so the list is long but by definition incomplete; don't hesitate to add additional type definitions. MIME type definitions found in mime-types are from RFCs, W3C recommendations, the {IANA Media Types registry}[https://www.iana.org/assignments/media-types/media-types.xhtml], and user contributions. It conforms to RFCs 2045 and 2231. This is release 2.6 with two new experimental features. The first new feature is a new default registry storage format that greatly reduces the initial memory use of the mime-types library. This feature is enabled by requiring +mime/types/columnar+ instead of +mime/types+ with a small performance cost and no change in *total* memory use if certain methods are called (see {Columnar Store}[#columnar-store] for more details). The second new feature is a logger interface that conforms to the expectations of an ActiveSupport::Logger so that warnings can be written to an application's log rather than the default location for +warn+. This interface may be used for other logging purposes in the future. mime-types 2.6 is the last planned version of mime-types 2.x, so deprecation warnings are no longer cached but provided every time the method is called. mime-types 2.6 supports Ruby 1.9.2 or later.

• minitest (5.7.0)

  gem install minitest -v "5.7.0"

  download delete

  minitest provides a complete suite of testing facilities supporting TDD, BDD, mocking, and benchmarking. "I had a class with Jim Weirich on testing last week and we were allowed to choose our testing frameworks. Kirk Haines and I were paired up and we cracked open the code for a few test frameworks... I MUST say that minitest is *very* readable / understandable compared to the 'other two' options we looked at. Nicely done and thank you for helping us keep our mental sanity." -- Wayne E. Seguin minitest/unit is a small and incredibly fast unit testing framework. It provides a rich set of assertions to make your tests clean and readable. minitest/spec is a functionally complete spec engine. It hooks onto minitest/unit and seamlessly bridges test assertions over to spec expectations. minitest/benchmark is an awesome way to assert the performance of your algorithms in a repeatable manner. Now you can assert that your newb co-worker doesn't replace your linear algorithm with an exponential one! minitest/mock by Steven Baker, is a beautifully tiny mock (and stub) object framework. minitest/pride shows pride in testing and adds coloring to your test output. I guess it is an example of how to write IO pipes too. :P minitest/unit is meant to have a clean implementation for language implementors that need a minimal set of methods to bootstrap a working test suite. For example, there is no magic involved for test-case discovery. "Again, I can't praise enough the idea of a testing/specing framework that I can actually read in full in one sitting!" -- Piotr Szotkowski Comparing to rspec: rspec is a testing DSL. minitest is ruby. -- Adam Hawkins, "Bow Before MiniTest" minitest doesn't reinvent anything that ruby already provides, like: classes, modules, inheritance, methods. This means you only have to learn ruby to use minitest and all of your regular OO practices like extract-method refactorings still apply.

  YamlDb is a database-independent format for dumping and restoring data. It complements the the database-independent schema format found in db/schema.rb. The data is saved into db/data.yml. This can be used as a replacement for mysqldump or pg_dump, but only for the databases typically used by Rails apps. Users, permissions, schemas, triggers, and other advanced database features are not supported - by design. Any database that has an ActiveRecord adapter should work.
