ObjectKind separates what an item is from how it draws: Object.Type
(a byte that doubled as the map character) becomes Kind ObjectKind,
with Glyph() producing the display character and objectKindForGlyph
converting back at the map boundary. KindWand covers the C 'stick'
category. The magic-missile bolt uses KindGold, matching C's literal
o_type='*' trick, with a comment.
PotionKind, ScrollKind, RingKind, WandKind, WeaponKind, ArmorKind and
TrapKind are now iota enums with Stringer (names come from the base
info tables); Object gains typed accessors (obj.RingKind(), ...) and
Launch is typed WeaponKind. beTrapped returns TrapKind. The
getItem/inventory/whatis prompt filters take ObjectKind, with
KindCallable/KindRingOrStick replacing the C CALLABLE/R_OR_S
sentinels; wizard.c's type_name table is subsumed by
ObjectKind.String(). IsRing/IsWearing/initWeapon/doPot signatures are
typed accordingly.
The save format version becomes 5.4.4-go2: the gob field rename would
otherwise silently zero Kind when reading old saves.
No behavior change; full suite green.
- potions.c completed: quaff with all 14 potion effects, the PACT
standard-fuse table (do_pot), raise_level; the see-invisible fruit-
juice message is computed at quaff time as in C
- scrolls.c in full: read_scroll with all 18 scroll effects including
the magic-mapping map rewrite and identify dispatch, uncurse
- options.c in full: the interactive options screen, get_bool/get_str/
get_inv_t/get_sf editors, ROGUEOPTS parsing (prefix matching, no-
prefixed booleans, ~ expansion), strucpy
- misc.c call_it via the get_str line editor
- turn_see gets a DaemonID (C casts it to a fuse callback for the
monster-detection potion)
Tests: healing/confusion potions with fuse burn-down, enchant armor,
hold monster, slow-monster zap, ROGUEOPTS parsing, and a regression
test documenting the C wake_monster ISGREED/ISHELD quirk the port
keeps faithfully.
rooms.c, passages.c, new_level.c ported in full: room/maze layout,
corridor spanning tree with extra connections, passage numbering flood
fill, trap/stairs/object placement, treasure rooms. Careful RNG-call
ordering throughout keeps generation seed-faithful to C.
Supporting subsystems this depends on, also ported:
- screen.go: curses replaced by in-memory Window cell buffers behind a
Terminal interface (tcell arrives with the UI phase; tests run headless)
- io.go: msg/addmsg/endmsg message-line protocol, status line, step_ok
- pack.c in full (add_pack sorting/stacking walk, get_item, inventory)
- things.c in full (inv_name, new_thing, discovery lists, pagination)
- monsters.c in full; chase.c navigation half (roomin/cansee/see_monst/
find_dest/runto/set_oldch); rings.c, armor.c in full
- weapons.c/sticks.c creation half (init_weapon, fix_stick, num)
- misc.c look() display update, eat, level-up, direction input
- daemons.c callbacks except stomach (needs death()) and the runners
chase driver (combat phase)
- init.c init_player with the starting kit
Tests: level invariants across seeds, determinism, 30-depth sweep.
