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

This package provides actionable code coverage reports for Ruby projects. It has very little overhead and can be easily integrated with development tools to catch coverage problems early.

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.

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.

ChunkyPNG is a pure Ruby library that can read and write Portable Network Graphics (PNG) images without depending on an external image library. It tries to be memory efficient and reasonably fast. It has features such as:

• Decoding support for any image that the PNG standard allows. This includes all standard color modes, all bit depths, all transparency, and interlacing and filtering options.

• Encoding support for images of all color modes (true color, grayscale, and indexed) and transparency for all these color modes. The best color mode is chosen automatically, based on the amount of used colors.

• Read/write access to the image's pixels.

• Read/write access to all image metadata that is stored in chunks.

• Memory efficiency: fixnum are used, i.e. 4 or 8 bytes of memory per pixel, depending on the hardware).

• Performance: ChunkyPNG is reasonably fast for Ruby standards, by only using integer math and a highly optimized saving routine.

• Interoperability with RMagick.

ChunkyPNG is vulnerable to decompression bombs and can run out of memory when loading a specifically crafted PNG file. This is hard to fix in pure Ruby. Deal with untrusted images in a separate process, e.g., by using fork or a background processing library.

This RSpec plugin makes it easy to mark test cases as pending or skipped for a specific Ruby engine (e.g. MRI or JRuby) or version combinations.

queue_classic is a queuing library for Ruby applications (Rails, Sinatra, etc.) queue_classic features asynchronous job polling, database maintained locks and has a single dependency, pg.

Lino provides an interface to run external commands. It provides an interface to add options as well as managing the standard input, output and error streams.

Niceogiri provides wrappers and helpers for XML manipulation using Nokogiri.

PandocRuby is a wrapper for Pandoc, a Haskell library with command line tools for converting one markup format to another. Pandoc can convert documents from a variety of formats including markdown, reStructuredText, textile, HTML, DocBook, LaTeX, and MediaWiki markup to a variety of other formats, including markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, HTML slide shows, EPUB, Microsoft Word docx, and more.

Wayback Machine Downloader is a command line tool for downloading websites from the Internet Archive's Wayback Machine (archive.org). It allows fine grained control over what to download by specifying which snapshots to consider and what files to include.

Prawn-dev contains tools to aid the development of the various Prawn projects.

Prawn is a pure Ruby PDF generation library.

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.

This package provides a Jekyll plugin to silently generate a sitemaps.org compliant sitemap for your Jekyll site.

multipart-parser is a simple parser for multipart MIME messages, written in Ruby, based on felixge/node-formidable's parser. It has the following characteristics:

• Pure Ruby

• Event-driven API

• Only supports one level of multipart parsing

• Does not perform I/O

• Does not depend on any other library.

Formatador is a Ruby library to format text printed to the standard output stream.

CiteProc is a citation processor interface and citation data API based on the CSL specifications. To actually process citations, a dedicated processor engine is required: a pure Ruby engine is available in the citeproc-ruby gem.

rb-inotify is a simple wrapper over the inotify Linux kernel subsystem for monitoring changes to files and directories.

HashDiff is a Ruby library to compute the smallest difference between two hashes.

This gems add the --watch switch to the jekyll CLI interface. It allows Jekyll to rebuild your site when a file changes.

Bio-commandeer provides an opinionated method of running shell commands from within Ruby. The advantage of bio-commandeer over other methods of running external commands is that when something goes wrong, messages printed to the STDOUT and STDERR streams are reported, giving extra detail to ease debugging.

Psych is a YAML parser and emitter. Psych leverages libyaml for its YAML parsing and emitting capabilities. In addition to wrapping libyaml, Psych also knows how to serialize and de-serialize most Ruby objects to and from the YAML format.

This package provides a collection of text algorithms: Levenshtein, Soundex, Metaphone, Double Metaphone, Porter Stemming.
