EmbeddedIFSession runs the hybrid interpreter in a daemon thread, bridged to the async MUD loop via threading.Event synchronization. .z3 files use the embedded path; other formats fall back to dfrotz. - MUD ZUI components: MudScreen (buffered output), MudInputStream (thread-safe input), MudFilesystem (quetzal saves), NullAudio - save/restore via QuetzalWriter/QuetzalParser and :: escape commands - state inspection: get_location_name(), get_room_objects() - error reporting for interpreter crashes - fix quetzal parser bit slice bug: _parse_stks used [0:3] (3 bits, max 7 locals) instead of [0:4] (4 bits, max 15) — Zork uses 15 |

mudlib
A telnet MUD engine. No client needed — just telnet and you're in.
Built on telnetlib3, Python 3.12+, managed with uv.
Quickstart
uv sync
just run
Then connect: telnet localhost 6789
Commands
just check # lint + typecheck + test
just run # start the server
just debug # start with debug logging
just render # generate world map HTML

How it works
The world is a toroidal 2D grid of terrain tiles, not discrete rooms. Players see a viewport centered on their position. Terrain types have mechanics — shallow water slows you, mountains block you, forests hide you.
Combat is timing-based with telegraphed moves and cooldown management, not turn-based.
The server runs a tick-based async game loop alongside the telnet server. SQLite handles persistence. Session mode stacks filter what reaches the player depending on context (exploring, fighting, composing, solving puzzles).
