Roxane embeds the operating system's webview (WebView2 / WKWebView / WebKitGTK, via the webview C library) in a native window and bridges it to Ruby with an invoke/emit operation channel — a lightweight, Tauri-shaped way to ship a web frontend as a desktop app, in Ruby.

FFI bindings to Google's PDFium library, the same engine that powers Chrome's PDF viewer. Provides text extraction with character-level metadata (font, weight, origin, angle), vector path access, image extraction, annotations, AcroForm fields, page rendering, and pdfplumber-style table detection. Inspired by pypdfium2 and pdfplumber.

Access help to the Ruby C library from FFI

Client for accessing the BEARS blockchain.

ruby-bindgen reads C and C++ headers with libclang and emits Ruby bindings. It supports three output formats: Rice C++ source for high-fidelity C++ wrappers, raw FFI for plain C libraries, and CMake build files to compile the generated extensions. Bindings are driven from a YAML configuration that controls header matching, symbol filtering, name mapping, and version guards. Battle-tested against OpenCV (thousands of classes) and PROJ.
