Rust Rogue

This is a Rust rewrite of Rogue: Exploring the Dungeons of Doom, based on the original C code forked from https://github.com/Davidslv/rogue. The project is now written entirely in Rust, with no C source code remaining.

ncurses is still required to build the game.

Develop Environment

nix develop

Build & run

cargo build --release
./target/release/rogue          # play
./target/release/rogue -d       # demo death screen
./target/release/rogue -s       # show high scores
./target/release/rogue FILE     # restore a saved game

Layout

• Cargo.toml: Crate definition. Produces both a library (rogue_rust, used for unit testing) and a native binary (rogue).
• src/bin/rogue.rs: Native Rust entry point. Builds the legacy C-style argv/envp arrays from std::env and hands them to startup::rogue_main.
• src/lib.rs: Rust module root.
• src/startup.rs: Process startup sequence (rogue_main, playit, quit, shell, my_exit, signal handlers).
• src/vers.rs: Version/identity strings (release, version, encstr, statlist) ported byte-for-byte from the old vers.c.
• src/globals.rs: Game-global variables, all exported with the legacy #[no_mangle] symbol names.
• src/machdep.rs / src/mdport.rs: Machine-dependent helpers and portability wrappers (originally mach_dep.c / mdport.c).
• src/curses.rs: C-shape ncurses wrappers (*mut c_void windows, raw string pointers) translating to the safe ncurses crate.
• src/rnd.rs: Random number generator state and legacy RNG symbols (rnd, set_seed) backed by the rand crate.
• src/level/: Level generation subsystem.
  • src/level/ffi.rs: Level creation entrypoints (new_level, find_floor) and internal room/passage drawing.
  • src/level/rooms.rs: Rust room model (Room, Structure layout).
  • src/level/passages.rs: Corridor/passage digging.
  • src/level/structure.rs: Generic 2D tile grid (Structure).
  • src/level/tile.rs: Tile enum used by the level model.
  • src/level/mod.rs: Level module root and public re-exports.
• src/game.rs: Shared CURRENT_LEVEL, monster/object lists, and game state backing the legacy save format.
• src/rndmove.rs: Random movement helper used by monster/player logic.
• src/level/trap.rs: Trap effects and trap-side status messaging.
• src/rip.rs: RIP tombstone art provider and end-of-run scoreboard.
• src/save.rs: Save/restore and autosave entrypoints (save_game, save_file, restore, auto_save).
• src/score.rs: Scoreboard persistence (rd_score, wr_score).
• src/rings.rs: Ring mechanics (ring_on, ring_off, gethand, ring_eat, ring_num).
• src/monsters.rs: Monster behavior helpers and save checks (randmonster, new_monster, wake_monster, etc.).
• src/potions.rs: Potion effects and visibility/status helpers (quaff, is_magic, invis_on, turn_see, seen_stairs, raise_level, do_pot).
• src/weapons.rs: Weapon/projectile handling and formatting (missile, do_motion, fall, wield, num, etc.).
• src/armor.rs: Armor equip/unequip and pass-turn helper functions (wear, take_off, waste_time).
• src/sticks.rs: Wand/staff behavior and charge formatting (fix_stick, do_zap, drain, fire_bolt, charge_str).
• src/scrolls.rs: Scroll effects and curses removal (read_scroll, uncurse).
• src/wizard.rs: Wizard helpers and debug commands (whatis, teleport, create_obj, show_map) with runtime global gating instead of #ifdef guards.
• src/player.rs: Shared C-layout bindings and player-facing helpers used across modules.
• src/command.rs, src/io.rs, src/fight.rs, src/chase.rs, src/daemon.rs, src/daemons.rs, src/draw.rs, src/misc.rs, src/options.rs, src/pack.rs, src/list.rs, src/things.rs, src/state.rs: Remaining gameplay subsystems, all in Rust.

C ABI notes

Although there is no C source left, many module boundaries still speak the legacy C ABI (fixed symbol names, #[repr(C)] layout mirrors, raw pointers), which keeps the port faithful to the original game and simplifies save-file compatibility.
