lithos is a self-contained embedded key-value store written from scratch as a native extension — no external database dependency. It uses a log-structured merge (LSM) tree: a write-ahead log makes every write durable, an in-memory sorted memtable flushes to immutable SSTables (with bloom filters)...

phylax (Greek "guardian") is a thin, safe-by-default binding to the Windows Cryptography API: Next Generation (CNG / bcrypt.dll) and DPAPI. It does not implement any cryptography of its own — it exposes the operating system's own validated primitives through an ergonomic, hard-to-misuse Ruby API:...

winclip is a native Windows clipboard library for Ruby. It gets and sets Unicode text, images (as PNG bytes, converted to/from CF_DIB/CF_DIBV5 via WIC), and file lists (CF_HDROP), plus clear, format introspection, and has_text?/has_image?/has_files? queries. The PNG image interface pairs directly...

windraw renders shapes and text into an off-screen bitmap using the graphics stack that already ships with Windows — Direct2D for vector drawing, DirectWrite for text, and WIC for PNG encoding — then saves a PNG to a file or returns the bytes as a string. A Cairo-style 2D canvas with no window or...

winipc is a native extension that exposes Windows local inter-process communication through an ergonomic, safe-by-default Ruby API: duplex named pipes (byte and message mode, with a server and a connect-with-retry client), pagefile-backed shared memory via named file mappings, and named synchroni...
