Audits every case label in C's command.c against this port's dispatch and leaves the audit behind as a standing test, so the two lists cannot drift again. A missing dispatch entry is the one porting error that leaves no trace at build time: the port is function-by-function, so every C function has a Go counterpart and a dropped key dangles nothing, fails to compile nowhere, and simply answers "illegal command" the first time a player presses it. That is how '+' (#11) survived until PR #30 found it by accident. Result: no further missing keys. '+' was the only one. Recording that as a negative result — the class of bug is real, it has now been searched for exhaustively rather than stumbled upon, and the search came back empty. Eighty labels: sixty-five in the main switch, fifteen in the wizard sub-switch. commandHandlers is pinned by set equality in both directions. A missing key is the '+' bug; an extra key is the same bug mirrored, since the likeliest way to acquire one is promoting a key out of the wizard sub-switch, which would expose a MASTER debug command in ordinary play. The main-switch keys that commandHandlers cannot hold - the goto-over re-dispatches, F-to-f, 'a' and 'm' - are covered separately through dispatchKey, because dropping one of those is just as silent as dropping a map entry. Two traps are documented in the file. rogue.h 52-53 defines when as break;case, so a grep for 'case ' finds ten of the eighty labels. And the main/wizard split is load-bearing: '+' was a divergence in ordinary play, not just wizard mode, precisely because it is a main-switch key. Confirms this port targets the MASTER build: all four #ifdef MASTER sites in command.c are ported unconditionally, as is sticks.c 237.
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.
