ruby-opencv is a wrapper of OpenCV for Ruby. It helps you to write computer vision programs (e.g. detecting faces from pictures) with Ruby.

Pik is a tool to manage multiple versions of ruby on Windows. It can be used from the Windows command line (cmd.exe), Windows PowerShell, or Git Bash. I have yet to test on cygwin. >pik help commands add Adds another ruby location to pik. benchmark|bench Runs bencmarks with all versions that pik is aware of. checkup|cu Checks your environment for current Ruby best practices. config Adds/modifies configuration options. default Switches back to the default settings. gem Runs the gem command with all versions that pik is aware of. gemsync Synchronizes gems from the version specified to the current version. help Displays help information. implode Removes your pik configuration. info Displays information about the current ruby version. install|in Downloads and installs different ruby versions. list|ls Lists ruby versions that pik is aware of. rake Runs the rake command with all versions that pik is aware of. remove|rm Removes a ruby location from pik. ruby|rb Runs ruby with all versions that pik is aware of. run Runs command with all versions of ruby that pik is aware of. switch|sw|use Switches ruby versions based on patterns. tag Adds the given tag to the current version. tags Runs the pik command against the given tags. uninstall|unin Deletes a ruby version from the filesystem and removes it from Pik. update|up updates pik. For help on a particular command, use 'pik help COMMAND'.

PIK is a tool to switch between multiple versions of ruby on Windows. You have to tell it where your different ruby versions are located using 'pik add'. Then you can change to one by using 'pik switch'. It also has a "sort of" multiruby functionality in 'pik run'.

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 profiles. Color 1.8 adds an alpha parameter to all <tt>#css_rgba</tt> calls, fixes a bug exposed by new constant lookup semantics in Ruby 2, and ensures that <tt>Color.equivalent?</tt> can only be called on Color instances. Barring bugs introduced in this release, this (really) is the last version of color that supports Ruby 1.8, so make sure that your gem specification is set properly (to <tt>~> 1.8</tt>) if that matters for your application. This version will no longer be supported one year after the release of color 2.0.

ZenTest provides 4 different tools: zentest, unit_diff, autotest, and multiruby. zentest scans your target and unit-test code and writes your missing code based on simple naming rules, enabling XP at a much quicker pace. zentest only works with Ruby and Minitest or Test::Unit. There is enough evidence to show that this is still proving useful to users, so it stays. unit_diff is a command-line filter to diff expected results from actual results and allow you to quickly see exactly what is wrong. Do note that minitest 2.2+ provides an enhanced assert_equal obviating the need for unit_diff autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests. multiruby runs anything you want on multiple versions of ruby. Great for compatibility checking! Use multiruby_setup to manage your installed versions. *NOTE:* The next major release of zentest will not include autotest (use minitest-autotest instead) and multiruby will use rbenv / ruby-build for version management.

OCRA (One-Click Ruby Application) builds Windows executables from Ruby source code. The executable is a self-extracting, self-running executable that contains the Ruby interpreter, your source code and any additionally needed ruby libraries or DLL.

Inline allows you to write foreign code within your ruby code. It automatically determines if the code in question has changed and builds it only when necessary. The extensions are then automatically loaded into the class/module that defines it. You can even write extra builders that will allow you to write inlined code in any language. Use Inline::C as a template and look at Module#inline for the required API.

Clarity - a log search tool By John Tajima & Tobi Lütke Clarity is a Splunk like web interface for your server log files. It supports searching (using grep) as well as trailing log files in realtime. It has been written using the event based architecture based on EventMachine and so allows real-time search of very large log files. If you hit the browser Stop button it will also kill the grep / tail utility. We wrote Clarity to allow our support staff to use a simple interface to look through the various log files in our server farm. The application was such a big success internally that we decided to release it as open source.

This is the MySQL API module for Ruby. It provides the same functions for Ruby programs that the MySQL C API provides for C programs. This package is offered as gem for easy installation using RubyGems. It wraps unmodified tmtm's mysql-ruby extension into a proper gem. Please note that tmtm (Tomita Mashahiro) has deprecated development of this extension and only update it for bug fixes.

Analyze code for potentially uncalled / dead methods, now with auto-removal.

ruby-mp3info read low-level informations and manipulate tags on mp3 files.

GeoHash encode/decode library for pure Ruby. It's implementation of http://en.wikipedia.org/wiki/Geohash

BlueCloth is a Ruby implementation of John Gruber's Markdown[http://daringfireball.net/projects/markdown/], a text-to-HTML conversion tool for web writers. To quote from the project page: Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML). It borrows a naming convention and several helpings of interface from {Redcloth}[http://redcloth.org/], Why the Lucky Stiff's processor for a similar text-to-HTML conversion syntax called Textile[http://www.textism.com/tools/textile/]. BlueCloth 2 is a complete rewrite using David Parsons' Discount[http://www.pell.portland.or.us/~orc/Code/discount/] library, a C implementation of Markdown. I rewrote it using the extension for speed and accuracy; the original BlueCloth was a straight port from the Perl version that I wrote in a few days for my own use just to avoid having to shell out to Markdown.pl, and it was quite buggy and slow. I apologize to all the good people that sent me patches for it that were never released. Note that the new gem is called 'bluecloth' and the old one 'BlueCloth'. If you have both installed, you can ensure you're loading the new one with the 'gem' directive: # Load the 2.0 version gem 'bluecloth', '>= 2.0.0' # Load the 1.0 version gem 'BlueCloth' require 'bluecloth'

Allows you to focus on a few tests with ease without having to use command-line arguments. Good for tools like guard that don't have enough brains to understand test output. Cf. minitest-autotest (an example of a test runner with strong testing logic). Inspired by https://github.com/seattlerb/minitest/issues/213

A Sinatra plugin to provide convenience whilst performing asynchronous responses inside of the Sinatra framework running under async webservers. To properly utilise this package, some knowledge of EventMachine and/or asynchronous patterns is recommended. Currently, supporting servers include: * Thin * Rainbows * Zbatery

Ruby Stats is a port of the statistics libraries from PHPMath. Probability distributions include binomial, beta, and normal distributions with PDF, CDF and inverse CDF as well as Fisher's Exact Test.

Vlad the Deployer is pragmatic application deployment automation, without mercy. Much like Capistrano, but with 1/10th the complexity. Vlad integrates seamlessly with Rake, and uses familiar and standard tools like ssh and rsync. Impale your application on the heartless spike of the Deployer.
