This package provides a fast and scalable test runner for Ruby.

This package extends the String class and adds a ColorizedString with methods to set text color, background color, and text effects.

This package is a collection of ANSI escape code related libraries enabling ANSI colorization and stylization of console output. Included in the library are the Code module, which defines ANSI codes as constants and methods, a Mixin module for including color methods, a Logger, a ProgressBar, and a String subclass. The library also includes a Terminal module which provides information about the current output device.

Solargraph provides a comprehensive suite of tools for Ruby programming: intellisense, diagnostics, inline documentation, and type checking.

Addressable is a replacement for the URI implementation that is part of Ruby's standard library. It more closely conforms to RFC 3986, RFC 3987, and RFC 6570 (level 4), providing support for IRIs and URI templates.

RubyPants is a Ruby port of the smart-quotes library SmartyPants. The original SmartyPants is a web publishing plug-in for Movable Type, Blosxom, and BBEdit that easily translates plain ASCII punctuation characters into smart typographic punctuation HTML entities.

The concurrent-ruby-edge gem includes concurrent-ruby features that are under active development and may change frequently. They are expected not to keep backward compatibility (there may also lack tests and documentation), although semantic versions are obeyed though. Features developed in concurrent-ruby-edge are expected to move to concurrent-ruby when final.

mkmf-lite is a light version of Ruby's mkmf.rb designed for use as a library. It does not create packages, builds, or log files of any kind. Instead, it provides mixin methods that you can use in FFI or tests to check for the presence of header files, constants, and so on.

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

Bacon is a small RSpec clone providing all essential features.

Asciidoctor PDF is an extension for Asciidoctor that converts AsciiDoc documents to Portable Document Format (PDF) using the Prawn PDF library. It has features such as:

• Direct AsciiDoc to PDF conversion

• Configuration-driven theme (style and layout)

• Scalable Vector Graphics (SVG) support

• PDF document outline (i.e., bookmarks)

• Table of contents page(s)

• Document metadata (title, authors, subject, keywords, etc.)

• Internal cross reference links

• Syntax highlighting with Rouge, Pygments, or CodeRay

• Page numbering

• Customizable running content (header and footer)

• “Keep together” blocks (i.e., page breaks avoided in certain block content)

• Orphaned section titles avoided

• Autofit verbatim blocks (as permitted by base_font_size_min setting)

• Table border settings honored

• Font-based icons

• Custom TrueType (TTF) fonts

• Double-sided printing mode (margins alternate on recto and verso pages)

TomParse is a TomDoc parser for Ruby. It takes a code comment as input and parses it into a convenient object-oriented structure in accordance with the TomDoc standard. See TomDoc for more information about the TomDoc format.

This library provides Ruby with an interface for validating JSON objects against a JSON schema conforming to JSON Schema Draft 4. Legacy support for JSON Schema Draft 3, JSON Schema Draft 2, and JSON Schema Draft 1 is also included.

This library provides a number of PDF::Reader based tools for use in testing PDF output. Presently, the primary purpose of this tool is to support the tests found in Prawn, a pure Ruby PDF generation library.

This package provides a generic object traverser for Ruby. It takes the object and recursively yields:

• the given object

• instance variables, class variables, constants

• Hash keys and values

• Enumerable members

• Struct members

• Data members

• Range begins and ends

Terminal Table is a fast and simple, yet feature rich table generator written in Ruby. It supports ASCII and Unicode formatted tables.

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.

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

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.

TTFunk is a TrueType font parser written in pure Ruby. It is used as part of the Prawn PDF generator.

The Pagination Generator forms the core of the pagination logic in Jekyll. It calculates and generates the pagination pages.

This package provides a JSON implementation written in pure Ruby.

This package provides a simple block-driven assertion library for both testing and for production code that attempts to make test definitions more readable.

Mustache is a framework-agnostic way to render logic-free views. Think of Mustache as a replacement for your views. Instead of views consisting of ERB or HAML with random helpers and arbitrary logic, your views are broken into two parts: a Ruby class and an HTML template.
