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:...

vcdeps wires Microsoft's vcpkg package manager into mkmf: declare native dependencies in ext/<gem>/vcpkg.json, call Vcdeps.mkmf! from extconf.rb, and vcdeps locates (or bootstraps) vcpkg, installs the ports out of tree with the correct dynamic-CRT triplet, prepends the include/lib paths so they w...

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...

winhttp is a native extension that binds the asynchronous WinHTTP API into a thin, hard-to-misuse Ruby HTTP client: system TLS via Schannel with the OS certificate store and revocation policy, the user's proxy and PAC settings, HTTP/2 negotiation, transparent gzip/deflate, safe redirect defaults,...

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...

winlog emits Windows ETW TraceLogging events from Ruby with no manifest, no message DLL, no registry writes, and no elevation: register a provider by name (standard ETW name-hashed GUID), then log runtime-dynamic events with typed fields (UTF-8 text, binary, int64, double, boolean) plus levels, k...

winproc is a native extension for controlling Windows processes the way the OS intends: argv-array spawning with exact quoting and per-handle inheritance (PROC_THREAD_ATTRIBUTE_HANDLE_LIST), job objects with kill-on-close so a spawned tree can never outlive you (even across a crash), atomic job p...

winreg is a native extension exposing the Win32 registry through a typed, hard-to-misuse Ruby API: strict typed readers and writers for REG_SZ, REG_EXPAND_SZ (never auto-expanded), REG_MULTI_SZ (correct double-NUL wire format), REG_DWORD/REG_QWORD (range-checked), and REG_BINARY, with raw escape ...

winsvc runs a Ruby process as a Windows service (SERVICE_WIN32_OWN_PROCESS) with correct service-control-manager integration: the control handler is pure C (no Ruby ever runs on an SCM thread), controls arrive on a Thread::Queue (fiber-scheduler cooperative), SERVICE_STOPPED is reported exactly o...

wintoast pops native Windows toast notifications from plain Ruby scripts using the WinRT notification API that ships with Windows — no Windows App SDK, no packaging, no COM activation server, no elevation — and drives progress on the taskbar button (ITaskbarList3) and the Windows Terminal tab (OS...

winwatch watches a directory (optionally a whole subtree) with a single overlapped ReadDirectoryChangesW operation and delivers :added/:modified/ :removed/:renamed events with absolute UTF-8 paths. Kernel buffer overflow is surfaced as an explicit :rescan event (never silently dropped) and a dyin...
