jaro_winkler is an implementation of Jaro-Winkler distance algorithm. It is written as a C extension and will fallback to a pure Ruby implementation on platforms where this is unsupported.

Spectroscope is a Behavior-Driven Development (BDD) framework built on RubyTest, designed to emulate RSpec in most respects. It is assertion framework independent so any number of assertion systems can be used, such as Assay or AE.

EventMachine implements a single-threaded engine for arbitrary network communications. EventMachine wraps all interactions with sockets, allowing programs to concentrate on the implementation of network protocols. It can be used to create both network servers and clients.

This gem implements bcrypt_pbkdf, which is a variant of PBKDF2 (Password-Based Key Derivation Function 2) with bcrypt-based pseudorandom function. This is currently used by net-ssh to read password encrypted Ed25519 keys.

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.

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.
