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).

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.
