Optimized XML (Ox) is a fast XML parser and object serializer for Ruby written as a native C extension. It was designed to be an alternative to Nokogiri and other Ruby XML parsers for generic XML parsing and as an alternative to Marshal for Object serialization.

Namae (名前) is a parser for human names. It recognizes personal names of various cultural backgrounds and tries to split them into their component parts (e.g., given and family names, honorifics etc.).

This gem provides a DSL that makes it easy to write reports of various types in ruby. It eliminates the need to litter your source with puts statements, instead providing a more readable, expressive interface to your application.

This package provides localhost, a Ruby library for Managing a local certificate authority for self-signed, localhost development servers.

This package provides a Ruby-based Parsing Expression Grammar (PEG) parser generator Domain Specific Language (DSL).

GemRelease is a gem plugin that aims at making gem development easier by automating repetitive work based on conventions, configuration, and templates.

CukeModeler facilitates modeling a test suite that is written in Gherkin (e.g. Cucumber, SpecFlow, Lettuce, etc.). It does this by providing an abstraction layer on top of the Abstract Syntax Tree (AST) that the cucumber-gherkin generates when parsing features, as well as providing models for feature files and directories in order to be able to have a fully traversable model tree of a test suite's structure. These models can then be analyzed or manipulated more easily than the underlying AST layer.

This package provides a SimpleCov formatter to generate a lcov-style coverage report.

Minitest-sprint is a test runner for minitest that makes it easier to re-run individual failing tests.

This package containse the XML parsing tools shared between a number of providers in the fog gem. fog is a Ruby cloud services library.

This package provides a gem to convert LaTeX input to Unicode. Its original use was as an input filter for BibTeX-Ruby, but it can be used independently to decode LaTeX. Many of the patterns used by this Ruby gem are based on François Charette's equivalent Perl module LaTeX::Decode.

This library provides functions to calculate the differences between two tree-like structures. It is similar to Ruby's built-in TSort module.

This package provides a parser for Ruby source code, written in C.

Temple is an abstraction and framework for compiling templates to pure Ruby.

Covered uses modern Ruby features to generate comprehensive coverage, including support for templates which are compiled into Ruby. It has the following features:

• Incremental coverage -- if you run your full test suite, and the run a subset, it will still report the correct coverage - so you can incrementally work on improving coverage.

• Integration with RSpec, Minitest, Travis & Coveralls - no need to configure anything - out of the box support for these platforms.

• It supports coverage of views -- templates compiled to Ruby code can be tracked for coverage reporting.

CharacterSet is a C-extended Ruby library to work with sets of Unicode code points. It can read and write these sets in various formats and implements the stdlib Set interface for them. It also offers an alternate paradigm of String processing which grants much better performance than Regexp and String methods from the stdlib where applicable. Many parts can be used independently, e.g.:

• CharacterSet::Character

• CharacterSet::Parser

• CharacterSet::Writer

• RangeCompressor

Zeitwerk implements constant autoloading with Ruby semantics. Each gem and application may have their own independent autoloader, with its own configuration, inflector, and logger. Supports autoloading, reloading, and eager loading.

Multihashes provides a simple, low-level multihash implementation for Ruby. A multihash is a digest with an embedded hash function code

Spy is a mocking library. By default, it will raise an error if you attempt to stub a method that doesn't exist or call the stubbed method with the wrong arity.

Kramdown is a library for parsing and converting a superset of Markdown. It is completely written in Ruby, supports standard Markdown (with some minor modifications) and various extensions that have been made popular by the PHP Markdown Extra package and Maruku.

Ruby dubugging companion: pretty print Ruby objects to visualize their structure. Supports custom object formatting via plugins.

The binding_of_caller module provides the Binding#of_caller method. It allows accessing bindings from upper frames in the call stack and can evaluate code in that context.

This gem provides parser dictionary data for AnyStyle.

Rouge is a code highlighter written in Ruby. It supports more than 100 languages and outputs HTML or ANSI 256-color text. Its HTML output is compatible with stylesheets designed for pygments.
