game/wizard.go had no tests of its own. It is not purely a debug surface: set_know writes the per-game discovered tables that name items in ordinary play, and teleport is what the teleport ring calls every fiftieth turn, so a defect in either leaks into a normal game. Adds coverage for createObj (pack filing and the gold arm), createWeaponArmor, createRing, showMap, whatis, whatisPick, setKnow, teleport and command.go's wizardKit. Package coverage 60.6% -> 62.4%. Expected values are transcribed from wizard.c, command.c, extern.c, weapons.c and rogue.h rather than read off the port; wizard mode is entered through Params.Wizard, the field main.go fills from ROGUE_WIZARD, so no test pokes the flag. Two notes from the C. A wizard-created "cursed" weapon is not cursed in either language: init_weapon assigns o_flags over the ISCURSED bit create_obj had just set, leaving only the o_hplus penalty, and the test pins the whole flag word to the init_dam[] row to say so. And show_map turns standout on for a square missing F_REAL but off only for a square whose whole flag word is zero. Exactly three sites clear F_REAL: putpass, which sets F_PASS first and so leaves 0x80; door's secret-door arm, on a room-wall exit still holding exactly F_REAL, leaving zero; and new_level's trap loop, whose rnd(NTRAPS) is 0..7, so the T_DOOR (00) case leaves zero as well. C's wstandend therefore does fire, at secret doors and unsprung trapdoors; what it gets wrong is leaking the attribute forward from a secret passage or a non-trapdoor trap until it reaches one of those - intermittent bands of reverse video, not a permanently reversed map. That display-only difference is reported on the issue and left alone here, and the test asserts standout only up to the first secret square. No game behavior is changed.
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

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: make test runs scripted command
sequences, dungeon-generation golden checks, and an RNG compatibility test
against the original C generator.
For development, the Makefile wraps the toolchain: make fmt (gofmt +
prettier), make lint (golangci-lint), make test (the suite, under the race
detector with coverage and a timeout), and make check (all three). Use the
targets rather than invoking go test directly — they carry the flags the
project relies on.
