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.

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.

Rexical is a lexical scanner generator that is used with Racc to generate Ruby programs. Rexical is written in Ruby.

Sprout is a modular set of tools that take the tedium and frustration out of creating and managing programming projects by automatically installing and configuring external tools, libraries, commands and build tasks. Bundles are currently available to support ActionScript 2, ActionScript 3, Flex and AIR development.

You can use this gem to create Ruby programs that work with audio, by reading and writing Wave sound files (*.wav). Since it is written in pure Ruby (as opposed to wrapping an existing C library), you can use it without having to compile a separate extension.

Cloud Translation can dynamically translate text between thousands of language pairs. Translation lets websites and programs programmatically integrate with the translation service. Note that google-cloud-translate-v3 is a version-specific client library. For most uses, we recommend installing the main client library google-cloud-translate instead. See the readme for more details.

This gem is intended to accomplish the same purpose as jStat js library: to provide ruby with statistical capabilities without the need of a statistical programming language like R or Octave. Some functions and capabilities are an implementation from other authors and are referenced properly in the class/method.

Ruby is an excellent programming language for creating and managing custom DSLs, but how can you securely evaluate a DSL while explicitly controlling the methods exposed to the user? Our good friends instance_eval and instance_exec are great, but they expose all methods - public, protected, and private - to the user. Even worse, they expose the ability to accidentally or intentionally alter the behavior of the system! The cleanroom pattern is a safer, more convenient, Ruby-like approach for limiting the information exposed by a DSL while giving users the ability to write awesome code!

ftpd is a pure Ruby FTP server library. It supports implicit and explicit TLS, IPV6, passive and active mode, and is unconditionally compliant per RFC-1123. It can be used as part of a test fixture or embedded in a program.

You've got a script. It's got some settings. Some settings are for this module, some are for that module. Most of them don't change. Except on your laptop, where the paths are different. Or when you're in production mode. Or when you're testing from the command line. "" So, Consigliere of mine, I think you should tell your Don what everyone knows. "" -- Don Corleone Configliere manage settings from many sources: static constants, simple config files, environment variables, commandline options, straight ruby. You don't have to predefine anything, but you can ask configliere to type-convert, require, document or password-obscure any of its fields. Modules can define config settings independently of each other and the main program.

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.

Packet, A Pure Ruby library for Event Driven Network Programming.

Clean and powerful library for game programming

Reactive programming framework for Ruby, painless evented IO, futures and an efficient byte buffer

The binary search algorithm is extracted from Jon Bentley's # Programming Pearls 2nd ed. p.93

Creates aliases for class methods, instance methods, constants, delegated methods and more. Aliases can be easily searched or saved as YAML config files to load later. Custom alias types are easy to create with the DSL Alias provides. Although Alias was created with the irb user in mind, any Ruby console program can hook into Alias for creating configurable aliases.

rmmseg-cpp is a high performance Chinese word segmentation utility for Ruby. It features full "Ferret":http://ferret.davebalmain.com/ integration as well as support for normal Ruby program usage. rmmseg-cpp is a re-written of the original RMMSeg(http://rmmseg.rubyforge.org/) gem in C++. RMMSeg is written in pure Ruby. Though I tried hard to tweak RMMSeg, it just consumes lots of memory and the segmenting process is rather slow. The interface is almost identical to RMMSeg but the performance is much better. This gem is always preferable in production use. However, if you want to understand how the MMSEG segmenting algorithm works, the source code of RMMSeg is a better choice than this.

# Excel to Code [](https://travis-ci.org/tamc/excel_to_code) excel_to_c - roughly translate some Excel files into C. excel_to_ruby - roughly translate some Excel files into Ruby. This allows spreadsheets to be: 1. Embedded in other programs, such as web servers, or optimisers 2. Without depending on any Microsoft code For example, running [these commands](examples/simple/compile.sh) turns [this spreadsheet](examples/simple/simple.xlsx) into [this Ruby code](examples/simple/ruby/simple.rb) or [this C code](examples/simple/c/simple.c). # Install Requires Ruby. Install by: gem install excel_to_code # Run To just have a go: excel_to_c <excel_file_name> This will produce a file called excelspreadsheet.c For a more complex spreadsheet: excel_to_c --compile --run-tests --settable <name of input worksheet> --prune-except <name of output worksheet> <excel file name> See the full list of options: excel_to_c --help # Gotchas, limitations and bugs 0. No custom functions, no macros for generating results 1. Results are cached. So you must call reset(), then set values, then read values. 2. It must be possible to replace INDIRECT and OFFSET formula with standard references at compile time (e.g., INDIRECT("A"&"1") is fine, INDIRECT(userInput&"3") is not. 3. Doesn't implement all functions. [See which functions are implemented](docs/Which_functions_are_implemented.md). 4. Doesn't implement references that involve range unions and lists (but does implement standard ranges) 5. Sometimes gives cells as being empty, when excel would give the cell as having a numeric value of zero 6. The generated C version does not multithread and will give bad results if you try. 7. The generated code uses floating point, rather than fully precise arithmetic, so results can differ slightly. 8. The generated code uses the sprintf approach to rounding (even-odd) rather than excel's 0.5 rounds away from zero. 9. Ranges like this: Sheet1!A10:Sheet1!B20 and 3D ranges don't work.

after_do is a gem that let's you execute a block of your choice after or before a specific method is called on a class. This is inspired by Aspect Oriented Programming and should be used to fight cross-cutting concerns.

RSRuby is a bridge library for Ruby giving Ruby developers access to the full R statistical programming environment. RSRuby embeds a full R interpreter inside the running Ruby script, allowing R methods to be called and data passed between the Ruby script and the R interpreter. Most data conversion is handled automatically, but user-definable conversion routines can also be written to handle any R or Ruby class.
