Simple ttf2eot convertor

Generates date & time events from recurrence rules to support various calendar and scheduling use cases, with an emphasis on speed; the core of the Reprise gem is implemented as a Rust extension to enable its use for performance-sensitive workloads.

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.

gem using RapidJSON as a backend to provide fast validation for JSON schemas

This is a learning experience. even gurus need help.

Interface to some features of iptables using libtipc

Ruby bindings (via Rust/magnus) for liblz4, using lz4-sys FFI. Provides block-format and frame-format LZ4 compress/decompress with optional dictionary support. Designed to be safe to call from multiple Ractors, unlike existing Ruby LZ4 gems.

RMagick is an interface between Ruby and ImageMagick. Fix for windows.

A ruby ffi wrapper for ModSecurity that also provides a Rack middleware

rookout is the Ruby SDK for the Rookout Debugging Platform

A safepoint-based sampling performance profiler that uses actual time deltas as weights to correct safepoint bias. Outputs JSON, pprof, collapsed stacks, or text report.

Rrtrace is a profiling tool that captures Ruby method calls and visualizes them using a high-performance Rust renderer.
