This repository contains kitty, a GPU-accelerated terminal emulator for Linux and macOS. It features a highly optimized C core for rendering, font shaping, and terminal emulation, with a Python configuration layer and a plugin system ("kittens") for features like file transfer, SSH integration, diff viewing, and hints. The codebase also includes a set of well-crafted Go libraries for CLI framework building, TUI event loops, fuzzy matching (Smith-Waterman variant), rsync delta patching, streaming base64, and color space conversions. These libraries are structurally independent and could be extracted into separate projects. The architecture is a monolith at the C/Python level with loosely coupled Go-based kittens that communicate via IPC. Build and packaging are handled by a custom system (bypy) and standard Python setup. The project is actively maintained with extensive CI, automated testing, and a responsive issue tracker.
