Nokogiri (鋸) is an HTML, XML, SAX, and Reader parser. Among Nokogiri's many features is the ability to search documents via XPath or CSS3 selectors. XML is like violence - if it doesn’t solve your problems, you are not using enough of it.

Ruby's Graph Library

IN ACTIVE DEVELOPMENT. High-performance Ruby game framework strongly influenced by the RPG Maker series by Enterbrain. The library contains multiple levels of abstraction, leveraging the power of modern OpenGL (C bindings built-in) and shaders, but building upon these low-level abstractions to create the user-friendly components that are to be expected in a 2D game framework, including sprites, textures, fonts, colors, etc. Those experienced with low-level graphics APIs have all the tools at their fingertips already built-in (OpenGL, GLFW, OpenAL, sound/font/image decoding, etc) and ready to build their own engine from, while those who have no interest in such can get started right away with powerful higher-level abstractions. While the library's API surface similar in many ways to RPG Maker XP/VX/VXA, bear in mind that it is merely incluenced by those, and liberal design changes have been taken to not limit the API or add restriction.
