BRASS (Bare-Metal Ruby Assertion System Standard) is a basic foundational assertions framework for other assertion and test frameworks to make use of.

ruby-hydra is a Ruby library for working with hyphenation patterns.

Org-ruby is an org-mode parser written in Ruby. The most significant thing this library does today is convert org-mode files to HTML or Textile or Markdown.

This package provides a Ruby implementation of the Coveralls API.

Method_source retrieves the source code for Ruby methods. Additionally, it can extract source code from Proc and Lambda objects or just extract comments.

rubocop is a Ruby code style checking tool. It aims to enforce the community-driven Ruby Style Guide.

Introspection provides tools to inspect the hierarchy of method definitions on a Ruby object.

Common protocol buffer types used by Google APIs

Provides empty Module#ruby2_keywords method, for the forward source-level compatibility against ruby2.7 and ruby3.

This library contains the Ruby extension that implements Protocol Buffers functionality in Ruby.

The Ruby extension makes use of generated Ruby code that defines message and enum types in a Ruby DSL. You may write definitions in this DSL directly, but we recommend using protoc's Ruby generation support with .proto files. The build process in this directory only installs the extension; you need to install protoc (in package ruby-grpc-tools) as well to have Ruby code generation functionality.

Warden is a Rack-based middleware that provides a mechanism for authentication in Ruby web applications.

This library provides a generic OAuth2 strategy for OmniAuth. It doesn't provide a way to gather user information, so should be used as a building block for authentication strategies.

This gem is a simple callback-based HTTP request/response parser for writing http servers, clients and proxies.

This package provides a pure Ruby library for event-driven IO.

This package allows loading, parsing and cascading Cascading Style Sheets (CSS) rule sets in Ruby.

This library contains some useful functionality to support the development of Ruby gems.

This gem generates a treemap showing the complexity of Ruby code on which it is run. It uses Saikuro under the covers to analyze Ruby code complexity.

Delayed_job (or DJ) encapsulates the common pattern of asynchronously executing longer tasks in the background. It is a direct extraction from Shopify where the job table is responsible for a multitude of core tasks.

Concurrent Ruby includes concurrency tools such as agents, futures, promises, thread pools, actors, supervisors, and more. It is inspired by Erlang, Clojure, Go, JavaScript, actors, and classic concurrency patterns.

Dalli is a high performance pure Ruby client for accessing memcached servers. Dalli supports:

• Simple and complex memcached configurations

• Fail-over between memcached instances

• Fine-grained control of data serialization and compression

• Thread-safe operation

• SSL/TLS connections to memcached

• SASL authentication.

The name is a variant of Salvador Dali for his famous painting The Persistence of Memory.

RangeCompresses is a tiny library that allows compressing arrays of objects into arrays of ranges. For example, it can turn the following: [1, 2, 3, 4, 6, 8, 9, 10] into [1..4, 6..6, 8..10].
