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

Hamster provides 6 persistent data structures: Hash, Vector, Set, SortedSet, List, and Deque (which works as an immutable queue or stack).

This package is probably useless outside of internal HashiCorp use. It is open source for disclosure and because HashiCorp's open source projects must be able to link to it.

This library makes it easier to discover the truth values of various Ruby objects.

This library allows reading and writing RPM packages. It is used by the fpm tool. It is written in pure Ruby because librpm is not available on all systems and requires many dependencies.

Pathutil tries to be a faster pure Ruby implementation of Pathname.

Benchmark-ips enhances the Ruby Benchmark module with the iterations per second count. For short snippets of code, it can automatically figure out how many times to run the code to get interesting data.

A Ruby gem for tokenizing, parsing, and transforming regular expressions. It comprises the following components:

• A scanner/tokenizer based on Ragel,

• A lexer that produces a stream of token objects,

• A parser that produces a tree of Expression objects.

This package is a Ruby parser library for Gemtext (hypertext format which is intended to serve as the native response format of the Gemini file transfer protocol) and produces a document object of various nodes.

Orderedhash is a Ruby library providing a hash implementation that preserves the order of items and features some array-like extensions.

RSpec::Wait strives to make it easier to test asynchronous or slow interactions.

This package provides a command line interface for running for Rack applications.

SDoc is an RDoc documentation generator to build searchable HTML documentation for Ruby code.

This package provides a class-level mixin to make managing fiber-local state easy. It provides easy access to a fiber-local state from a fiber, and defaults to a shared thread-local state.

YARD is a documentation generation tool for the Ruby programming language. It enables the user to generate consistent, usable documentation that can be exported to a number of formats very easily, and also supports extending for custom Ruby constructs such as custom class level definitions.

Fuubar is an RSpec formatter that uses a progress bar instead of a string of letters and dots as feedback. It also stops on the first test failure.

Rubytest CLI is a command-line interface for running tests for Rubytest-based test frameworks. It provides the rubytest executable.

This package provides a performant priority queue in pure ruby with support for changing priority using pairing heap data structure

Clamp provides an object-model for command-line utilities. It handles parsing of command-line options, and generation of usage help.

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.

Sentry provides a gem that provides a client interface for the Sentry error logger.

This package provides a RBTree is a sorted associative collection that is implemented with a Red-Black Tree. It maps keys to values like a Hash, but maintains its elements in ascending key order. The interface is the almost identical to that of Hash.

childprocess provides a gem to control external programs running in the background, in Ruby.

This gem provides the classes LinkHeader and LinkHeader::Link, which represent HTTP Link headers conforming to RFC 5988. Objects can be constructed from and converted to text or a JSON-friendly Array representation. They can also be used to generate corresponding HTML link elements.
