Replace .golangci.yml with the shared canonical config. The old
config's top-level linters-settings block was silently ignored under
the v2 schema, so the lll/funlen/cyclop/dupl thresholds now actually
apply. The four repo-specific disables (mnd, exhaustive, paralleltest,
testpackage) move out of the config into targeted in-code nolint
directives carrying their original approval dates, keeping the config
byte-identical to the canonical one.
Fixes surfaced by the stricter settings: t.Parallel() added to all 32
tests, 24 overlong lines wrapped or their comments tightened, tcell
control-code returns rewritten as character literals, dupl markers on
the identically-shaped item data tables, and two wsl_v5 defer cuddles.
No behavior changes. The repo has no golangci-lint version pin (no
Dockerfile or CI; make lint runs the host binary, currently v2.12.2),
so there was nothing to bump.
.golangci.yml is the prompts-repo standard verbatim plus one approved
exception (paralleltest, sneak 2026-07-06). Roughly 1,500 findings
fixed:
- autofix sweep (wsl_v5/nlreturn/intrange/modernize formatting), with
the misspell autofix REVERTED where it rewrote authentic C game text
("missle vanishes" stays, with nolint and a comment)
- error handling: errcheck sites get real handling — saveFile now
closes explicitly and removes corrupt saves, scoreboard writes are
documented best-effort, err113 sentinel errors (ErrSaveOutOfDate,
ErrScreenTooSmall); panics allowed for unrecoverable states per
MEMORY.md policy
- gosec: real fixes (ParseInt for SEED, 0600 scorefile) and justified
per-line nolints for provably-bounded conversions (randomMonsterLetter
helper collapses eight rnd(26)+'A' sites)
- API tidying from linters: pointer receivers on flag types
(recvcheck), msg helpers renamed addmsgf/doaddf/Printwf/MvPrintwf
(goprintffuncname), myExit()/findFloor(monst)/mkGameInput(t) drop
always-constant params (unparam), gameEnd carries no status
- gocritic/staticcheck: if-else chains to switches, the pack.c
inventory filter untangled into matchesFilter, main.go split so
defers run before exit (exitAfterDefer, funlen)
- revive doc comments on all exported flag types/consts/methods
Remaining findings are confined to linters pending sneak's exception
decision (mnd, gochecknoglobals, cyclop, nestif, gocognit, exhaustive,
goconst, testpackage); TODO.md records the state. MEMORY.md added at
repo root as the project's agent working notes.
Module sneak.berlin/go/rogue, package game:
- types.go: all rogue.h constants, flag types, Coord/Stats/Room/ObjInfo
- creature.go/object.go: the THING union split into Creature (Player/
Monster) and Object; slices replace the C linked lists
- level.go: Place map with the C column-major layout and chat/flat/moat/
winat access methods
- tables.go: extern.c + init.c data (bestiary, item tables, name pools)
- rng.go: the exact C LCG (seed*11109+13849), golden-tested against a
compiled C reference for seed compatibility
- init.go: per-game item appearance randomization (init.c)
- daemon.go/daemons.go: scheduler with DaemonID replacing function
pointers (ids match the C save format's mapping)
- game.go: RogueGame holds all former globals; NewGame constructor
