# Status

pre-1.0

The port on main is complete and faithful (function-by-function from
Rogue 5.4.4 C; reference sources on c-master/modern-rogue). Current
phase: refactor from a transliterated port into idiomatic Go — one
feature branch per step below, descriptive naming, real types, house
style per ~/dev/prompts/prompts/CODE_STYLEGUIDE_GO.md.

Refactor ground rules:

- Behavior must not change unless a step says so. The full test suite
  (scripted sessions, generation invariants, C-compatible RNG goldens)
  gates every step; 80x24 seed-compatible gameplay stays intact.
- Renames keep the C lineage greppable: doc comments retain their
  "(file.c func_name)" breadcrumbs, and the docs refresh step adds a
  C-name → Go-name table to ARCHITECTURE.md.

# Next Step

Adopt the house Go linting standards: copy .golangci.yml from the
prompts repo and bring game/, term/, and cmd/ lint-clean (the port is
greenfield code, so no exemptions apply).

# Completed Steps

- 2026-07-06 Module base path updated to git.eeqj.de/sneak/rgoue
  (go.mod, term/ and cmd/ imports, ARCHITECTURE.md, version string).
- 2026-07-06 Refactor step 3 (refactor/object-fields): Object.Arm split
  into ArmorClass/Charges/GoldValue/Bonus (rings); Stats.Arm →
  ArmorClass; damage strings parsed once into DiceSpec at table
  definition (ParseDice keeps C roll_em parse semantics, incl. "%%%x0"
  and "000x0" edge cases, regression-tested); save format 5.4.4-go3.
- 2026-07-06 Refactor step 2 (refactor/typed-kinds, b940cfc):
  ObjectKind separates item category from map glyph (Object.Type byte
  → Kind ObjectKind with Glyph()); PotionKind/ScrollKind/RingKind/
  WandKind/WeaponKind/ArmorKind/TrapKind typed iota enums with
  Stringer; typed accessors on Object; getItem/inventory/whatis
  filters take ObjectKind (KindCallable/KindRingOrStick replace
  CALLABLE/R_OR_S); save format bumped to 5.4.4-go2. Suite green.
- 2026-07-06 Refactor step 1 (refactor/descriptive-constants): renamed
  all flag bits, trap types, item subtype constants, and Max* counts to
  descriptive names (IsHuh→Confused, SeeMonst→SenseMonsters,
  WsHasteM→WandHasteMonster, MaxSticks→NumWandTypes, ...);
  Level.NTraps→TrapCount; C names kept as comment breadcrumbs. Pure
  rename, suite green.
- 2026-07-06 Made the rgoue branch Go-only: removed C sources and the
  autoconf/VS build system (they remain on master and modern-rogue),
  ported the last wizard command (item-probability listing), rewrote
  README.md for the Go port (c0b533e)
- 2026-07-06 Ported the command loop, save/restore, the tcell terminal
  layer, and the playable binary at cmd/rogue (41fc104)
- 2026-07-06 Ported item effects: potions, scrolls, options, call_it
  (cdf9bf7)
- 2026-07-06 Ported combat, the chase driver, traps, zapping, death and
  scores (3c5add8)
- 2026-07-06 Ported dungeon generation, base items, the pack, and
  monster creation (a69ef7d)
- 2026-07-06 Ported the foundation: types, seed-compatible RNG, item
  tables, daemon scheduler (7fa2048)
- 2026-07-06 Wrote ARCHITECTURE.md Parts 1 and 2: complete map of the C
  program and the Go port design (91eeee0, 45dba95)
- Fork base: Davidslv/rogue C 5.4.4 with modernization fixes (C23
  prototypes, ncurses compat), preserved on master/modern-rogue

# Future Steps

1. Refactor step 4: method renames, movement/world subsystem
   (doMove→moveHero, beTrapped→springTrap, rndmove→randomStep,
   doRooms/doPassages/doMaze→digRooms/digPassages/digMaze,
   chgStr→changeStrength, ...); remove the goto/label flows in doMove,
   dispatch, and saveGame in favor of loops and helpers.
2. Refactor step 5: method renames, items/combat/UI subsystems
   (invName→inventoryName, rollEm→rollAttacks, doPot→applyPotionFuse,
   getItem→promptPackItem returning (obj, ok), getDir→promptDirection);
   int status codes (attack returning -1) become named results. Two or
   three commits, one subsystem each.
3. Refactor step 6: extract types from the god object — MessageLine
   owns the msg/addmsg/endmsg machinery; pack/inventory operations move
   onto *Player; monster/object list management and map queries
   consolidate onto *Level; RogueGame keeps turn orchestration and
   cross-system effects only.
4. Refactor step 7: effects dispatch — the giant quaff/readScroll/doZap
   switches become per-kind handler tables of small named methods,
   keeping effect order and RNG call sequence identical.
5. Refactor step 8: constructor and style pass per the house
   styleguide — game.New(game.Params{...}) replacing NewGame(Config);
   replace the gameEnd panic unwind with error-based turn results where
   feasible; 77-column wrap sweep.
6. Docs refresh: update ARCHITECTURE.md Part 2 and README.md for the
   post-refactor names; add the C name → Go name rename table.
7. Playtest hardening pass: play several full games with the tcell
    binary and extend run_test.go to script a deeper multi-level
    playthrough (descend past level 5, use potions, scrolls, zapping,
    save/restore). Fix any panics, message mismatches, or divergences
    from the C behavior that this uncovers, with regression tests.
8. Verify the seed-compatibility claim against the C reference on
    c-master: same seed, same dungeon, same item tables, for several
    seeds.
9. Broaden unit test coverage where playtesting finds thin spots
    (rings, sticks, wizard commands).
10. Tag a release once a full game (Amulet retrieval and score entry)
    completes without defects.
11. Full-terminal-size support (deferred by explicit decision
    2026-07-06): per-game dungeon dimensions instead of the 80x24
    constants; open design questions are resize policy, gameplay
    tuning at larger sizes, and a --classic 80x24 mode.
12. Note: this repo is exempt from the standard policy scaffold. Do not
    add Makefile, Dockerfile, or REPO_POLICIES.md.
