VersionGem aims to provide introspection of a Version module based on a Version::VERSION constant string wile not interfering with gemspec parsing where the VERSION string is traditionally used.

BibTeX-Ruby is the Rubyist's Swiss Army knife for all things BibTeX. It includes a parser for all common BibTeX objects and a sophisticated name parser that tokenizes correctly formatted names. BibTeX-Ruby recognizes BibTeX string replacements, joins values containing multiple strings or variables, supports cross-references, and decodes common LaTeX formatting instructions to unicode. If you are in a hurry, it also allows for easy export/conversion to formats such as YAML, JSON, CSL, and XML (BibTeXML).

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.

Oedipus Lex is a lexer generator in the same family as Rexical and Rex. It is based primarily on generating code much like you would a hand-written lexer. It uses StrScanner within a multi-level case statement. As such, Oedipus matches on the first match, not the longest.

Syntax Tree is a suite of tools built on top of the internal CRuby parser. It provides the ability to generate a syntax tree from source, as well as the tools necessary to inspect and manipulate that syntax tree. It can be used to build formatters, linters, language servers, and more.

Text::Hyphen is a Ruby library to hyphenate words in various languages using Ruby-fied versions of TeX hyphenation patterns.

It includes reporting in HTML, CSV or iCalendar format and an email based status tracking system to send and receive time sheets from collaborators.

It covers the complete spectrum of project management tasks from the first idea to the completion of the project. It assists you during project scoping, resource assignment, cost and revenue planning, risk and communication management, status tracking and reporting.

Turbo aims to be as fast as single-page web application without having to write any JavaScript. Turbo accelerates links and form submissions without requiring server-side changes to the generated HTML. It allows carving up a page into independent frames, which can be lazy-loaded and operated as independent components. Finally, it helps making partial page updates using just HTML and a set of CRUD-like container tags. These three techniques reduce the amount of custom JavaScript that many web applications need to write by an order of magnitude. And for the few dynamic bits that are left, Stimulus can be used.

Gherkin-ruby is a Gherkin parser written in pure Ruby and less than 200 lines of code.
