Here is the list of GEMs and their info that are included in the CLOUDFORMS 5.2.3 appliance. I thought it would be useful to post, I need this recently for some work I am doing. It was really easy as most things in CLOUDFORMS usually are I simply wrote some ruby to utilise an existing gem called GEMS, that pulls this data from I wrapped the code in some file open and close, e.g. I dumped the list of gems in the appliance using “gem list > gems.txt” then had my little nugget of code read that in. Here it is.

require 'rubygems'
require 'gems'

If you want to write your own AMQP client, this gem can help you with that.
ancestry Ancestry allows the records of a ActiveRecord model to be organized in a tree
structure, using a single, intuitively formatted database column. It exposes
all the standard tree structure relations (ancestors, parent, root, children,
siblings, descendants) and all of them can be fetched in a single sql query.
Additional features are named_scopes, integrity checking, integrity restoration,
arrangement of (sub)tree into hashes and different strategies for dealing with
orphaned records.

color Color is a Ruby library to provide basic RGB, CMYK, HSL, and other colourspace
manipulation support to applications that require it. It also provides 152
named RGB colours (184 with spelling variations) that are commonly supported in
HTML, SVG, and X11 applications. A technique for generating monochromatic
contrasting palettes is also included.The Color library performs purely mathematical manipulation of the colours
based on colour theory without reference to colour profiles (such as sRGB or
Adobe RGB). For most purposes, when working with RGB and HSL colour spaces,
this won’t matter. Absolute colour spaces (like CIE L*a*b* and XYZ) and cannot
be reliably converted to relative colour spaces (like RGB) without colour

Color version 1.6 primarily adds a colour matching method for RGB and
experimental CIE L*a*b* and XYZ conversion methods for use with the colour
matching method.

Barring bugs introduced in this release, this is the last version of color that
supports Ruby 1.8, so make sure that your gem specification is set properly (to
~> 1.6) if that matters for your application.

colored >> puts “this is red”.red

>> puts “this is red with a blue background (read: ugly)”.red_on_blue

>> puts “this is red with an underline”.red.underline

>> puts “this is really bold and really blue”

>> logger.debug “hey this is broken!”.red_on_yellow # in rails

>> puts “This is red” # but this part is mostly untested

daemons Daemons provides an easy way to wrap existing ruby scripts (for example a self-written server) to be run as a daemon and to be controlled by simple start/stop/restart commands. You can also call blocks as daemons and control them from the parent or just daemonize the current process. Besides this basic functionality, daemons offers many advanced features like exception backtracing and logging (in case your ruby script crashes) and monitoring and automatic restarting of your processes if they crash.

eventmachine EventMachine implements a fast, single-threaded engine for arbitrary network
communications. It’s extremely easy to use in Ruby. EventMachine wraps all
interactions with IP sockets, allowing programs to concentrate on the
implementation of network protocols. It can be used to create both network
servers and clients. To create a server or client, a Ruby program only needs
to specify the IP address and port, and provide a Module that implements the
communications protocol. Implementations of several standard network protocols
are provided with the package, primarily to serve as examples. The real goal
of EventMachine is to enable programs to easily interface with other programs
using TCP/IP, especially if custom protocols are required.

haml Haml (HTML Abstraction Markup Language) is a layer on top of HTML or XML that’s
designed to express the structure of documents in a non-repetitive, elegant, and
easy way by using indentation rather than closing tags and allowing Ruby to be
embedded with ease. It was originally envisioned as a plugin for Ruby on Rails,
but it can function as a stand-alone templating engine.
haml-rails Haml-rails provides Haml generators for Rails 3. It also enables Haml as the templating engine for you, so you don’t have to screw around in your own application.rb when your Gemfile already clearly indicated what templating engine you have installed. Hurrah.
handsoap Handsoap is a library for creating SOAP clients in Ruby
highline A high-level IO library that provides validation, type conversion, and more for
command-line interfaces. HighLine also includes a complete menu system that can
crank out anything from simple list selection to complete shells with just
minutes of work.

hirb Hirb provides a mini view framework for console applications and uses it to improve ripl(irb)’s default inspect output. Given an object or array of objects, hirb renders a view based on the object’s class and/or ancestry. Hirb offers reusable views in the form of helper classes. 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.
hoe Hoe is a rake/rubygems helper for project Rakefiles. It helps you
manage, maintain, and release your project and includes a dynamic

i18n New wave Internationalization support for Ruby.
inifile Although made popular by Windows, INI files can be used on any system thanks
to their flexibility. They allow a program to store configuration data, which
can then be easily parsed and changed. Two notable systems that use the INI
format are Samba and Trac.More information about INI files can be found on the [Wikipedia Page](

### Properties

The basic element contained in an INI file is the property. Every property has
a name and a value, delimited by an equals sign *=*. The name appears to the
left of the equals sign and the value to the right.


### Sections

Section declarations start with *[* and end with *]* as in `[section1]` and
`[section2]` shown in the example below. The section declaration marks the
beginning of a section. All properties after the section declaration will be
associated with that section.

### Comments

All lines beginning with a semicolon *;* or a number sign *#* are considered
to be comments. Comment lines are ignored when parsing INI files.

### Example File Format

A typical INI file might look like this:

; some comment on section1
var1 = foo
var2 = doodle
var3 = multiline values
are also possible

# another comment
var1 = baz
var2 = shoodle

map the awesome ruby container you’ve always wanted: a string/symbol indifferent ordered hash that works in all rubies
mime-types 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 programmatically. There are many types defined by RFCs and
vendors, so the list is long but by definition incomplete; don’t hesitate to to
add additional type definitions (see Contributing.rdoc). The primary sources
for MIME type definitions found in mime-types is the IANA collection of
registrations (see below for the link), RFCs, and W3C recommendations.

This is release 2.2, mostly changing how the MIME type registry is updated from
the IANA registry (the format of which was incompatibly changed shortly before
this release) and taking advantage of the extra data available from IANA
registry in the form of MIME::Type#xrefs. In addition, the {LTSW
list}[] has been dropped as a
supported list.

As a reminder, mime-types 2.x is no longer compatible with Ruby 1.8 and
mime-types 1.x is only being maintained for security issues. No new MIME types
or features will be added.

mime-types (previously called MIME::Types for Ruby) was originally based on
MIME::Types for Perl by Mark Overmeer, copyright 2001 – 2009. It is built to
conform to the MIME types of RFCs 2045 and 2231. It tracks the {IANA Media
Types registry}[]
with some types added by the users of mime-types.

minitest 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

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

minitest/spec is a functionally complete spec engine. It hooks onto
minitest/unit and seamlessly bridges test assertions over to spec

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

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. 😛

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

“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.

more_core_extensions MoreCoreExtensions are a set of core extensions beyond those provided by ActiveSupport.

net-http-persistent Manages persistent connections using Net::HTTP plus a speed fix for Ruby 1.8.
It’s thread-safe too!Using persistent HTTP connections can dramatically increase the speed of HTTP.
Creating a new HTTP connection for every request involves an extra TCP
round-trip and causes TCP congestion avoidance negotiation to start over.

Net::HTTP supports persistent connections with some API methods but does not
handle reconnection gracefully. Net::HTTP::Persistent supports reconnection
and retry according to RFC 2616.

net-ldap Net::LDAP for Ruby (also called net-ldap) implements client access for the
Lightweight Directory Access Protocol (LDAP), an IETF standard protocol for
accessing distributed directory services. Net::LDAP is written completely in
Ruby with no external dependencies. It supports most LDAP client features and a
subset of server features as well.Net::LDAP has been tested against modern popular LDAP servers including
OpenLDAP and Active Directory. The current release is mostly compliant with
earlier versions of the IETF LDAP RFCs (2251–2256, 2829–2830, 3377, and 3771).
Our roadmap for Net::LDAP 1.0 is to gain full client compliance with
the most recent LDAP RFCs (4510–4519, plus portions of 4520–4532).
net-ping The net-ping library provides a ping interface for Ruby. It includes
separate TCP, HTTP, LDAP, ICMP, UDP, WMI (for Windows) and external ping

netrc This library can read and update netrc files, preserving formatting including comments and whitespace.
nokogiri Nokogiri (鋸) is an HTML, XML, SAX, and Reader parser. Among Nokogiri’s
many features is the ability to search documents via XPath or CSS3 selectors.XML is like violence – if it doesn’t solve your problems, you are not using
enough of it.

pg Pg is the Ruby interface to the {PostgreSQL RDBMS}[].

It works with {PostgreSQL 8.4 and later}[].

A small example usage:

#!/usr/bin/env ruby

require ‘pg’

# Output a table of current connections to the DB
conn = PG.connect( dbname: ‘sales’ )
conn.exec( “SELECT * FROM pg_stat_activity” ) do |result|

rake Rake is a Make-like program implemented in Ruby. Tasks and dependencies are
specified in standard Ruby syntax.Rake has the following features:

* Rakefiles (rake’s version of Makefiles) are completely defined in
standard Ruby syntax. No XML files to edit. No quirky Makefile
syntax to worry about (is that a tab or a space?)

* Users can specify tasks with prerequisites.

* Rake supports rule patterns to synthesize implicit tasks.

* Flexible FileLists that act like arrays but know about manipulating
file names and paths.

* A library of prepackaged tasks to make building rakefiles easier. For example,
tasks for building tarballs and publishing to FTP or SSH sites. (Formerly
tasks for building RDoc and Gems were included in rake but they’re now
available in RDoc and RubyGems respectively.)

* Supports parallel execution of tasks.

tilt Generic interface to multiple Ruby template engines
timecop A gem providing “time travel” and “time freezing” capabilities, making it dead simple to test time-dependent code. It provides a unified method to mock,, and in a single call.
transaction-simple Transaction::Simple provides a generic way to add active transaction support to
objects. The transaction methods added by this module will work with most
objects, excluding those that cannot be Marshal-ed (bindings, procedure
objects, IO instances, or singleton objects).The transactions supported by Transaction::Simple are not associated with any
sort of data store. They are “live” transactions occurring in memory on the
object itself. This is to allow “test” changes to be made to an object before
making the changes permanent.

Transaction::Simple can handle an “infinite” number of transaction levels
(limited only by memory). If I open two transactions, commit the second, but
abort the first, the object will revert to the original version.

Transaction::Simple supports “named” transactions, so that multiple levels of
transactions can be committed, aborted, or rewound by referring to the
appropriate name of the transaction. Names may be any object except nil.

Transaction groups are also supported. A transaction group is an object wrapper
that manages a group of objects as if they were a single object for the purpose
of transaction management. All transactions for this group of objects should be
performed against the transaction group object, not against individual objects
in the group.

Version 1.4.0 of Transaction::Simple adds a new post-rewind hook so that
complex graph objects of the type in tests/tc_broken_graph.rb can correct

Version just fixes a simple bug with #transaction method handling
during the deprecation warning.

Version is a small update for people who use Transaction::Simple in
bundler (adding lib/transaction-simple.rb) and other scenarios where having Hoe
as a runtime dependency (a bug fixed in Hoe several years ago, but not visible
in Transaction::Simple because it has not needed a re-release). All of the
files internally have also been marked as UTF-8, ensuring full Ruby 1.9
