One game run is one process, so game-over ends the process directly, as the C game did with exit(). myExit now restores the terminal (via the new Terminal.Fini) and calls os.Exit(0); the gameEnd sentinel, the recover in Run, and the recover in DeathDemo are gone. Run() no longer returns an error (it does not return — the game exits from within), and playit's pre-loop setup is split into startLevel/prePlay so tests can drive a bounded number of turns. Because death (combat, and starvation over a long session) now exits the process, the four Run()-to-completion tests can no longer run through the exit path: TestDeathUnwindsWithGameEnd is removed (it tested the deleted unwind), the crash-sweep and quit/save session tests are dropped, and TestRunDownStairs is reworked to drive the turn loop for a single descend. Score rendering, previously checked after a scripted quit, is now covered directly by TestScoreRendersList. Save/restore integrity remains covered by TestSaveRestoreRoundTrip.
Rogue: Exploring the Dungeons of Doom (Go port)
Rogue is the original dungeon-crawling adventure game that spawned an entire genre. This branch is a faithful Go port of Rogue 5.4.4: explore procedurally generated dungeons, fight monsters, collect treasure, and attempt to retrieve the Amulet of Yendor.
Original authors: Michael Toy, Ken Arnold, and Glenn Wichman (1980–1983, 1985, 1999).
The port is function-by-function faithful to the classic C sources — same
dungeon generation (seed-compatible RNG), same combat math, same item tables,
same messages. The C reference implementation lives on the master and
modern-rogue branches; ARCHITECTURE.md documents both the
original program structure and the design of this port.
Building and running
Requires Go 1.25 or later and a terminal at least 80x24.
go build ./cmd/rogue
./rogue
# Restore a saved game
./rogue ~/rogue.save
# View high scores
./rogue -s
# Test the death screen (demo mode)
./rogue -d

Environment
# Game options, as in the original
export ROGUEOPTS="name=YourName,terse,jump,fruit=mango"
# Wizard (debug) mode, with a reproducible dungeon

The scoreboard is kept in ~/.rogue.scores. Save files are Go gob snapshots
and, as in the original, are deleted when restored.
Code layout
game/ the game engine: one Go file per original C file,
function-by-function (see ARCHITECTURE.md for the mapping)
term/ tcell-backed terminal, replacing curses
cmd/rogue/ the executable
The engine package is fully headless-testable: go test ./game/ runs scripted
game sessions, dungeon-generation golden checks, and an RNG compatibility test
against the original C generator.
