What's New

Added

  • qwertz option for QWERTZ keyboards (off by default): with HACKOPTIONS=qwertz the key labelled Z moves northwest and the one labelled Y zaps, as in NetHack's swap_yz. Contributed by @neuhaus; a counted zap (2y) replayed as a move until fixed before merge. CI now checks the bindings and the counted replay (.github/scripts/qwertz-test.exp). (#29, #40)
  • README: link to the bare-metal Raspberry Pi Pico (RP2040) port by @neuhaus. (#26)

Changed

  • dev/ soak setup: hardened lane runnable (run-hardened.py, run-all.py --hardened, in the default set); --seed-offset for fresh dungeons per soak and --only-run to replay one run; enhanced mode adds </> and terminal shrink/restore cycles; moves drain output instead of sleeping (1000-step runs practical); non-zero game exit now fails a run; soak recipe in dev/README.
  • dev/ sanitizer harness: runners start (H1), cleanup stays inside the lane's hackdir (H3), sanitizer log files and failed quits now fail runs (H2, H4), --steps honoured, README fixed (H5); test builds (-DHACK_TEST_SEED) seed the game RNG from HACK_SEED so runs replay; hardened lane now configures (RelWithDebInfo, _FORTIFY_SOURCE=3).
  • README: Hack 1.0.3 is dated 1985 (not 1984); security and strength-overflow claims reworded to match what was actually fixed; protoHack description credits Brian Harvey and Dan Stormont for preserving and publishing Fenlason's source.
  • README: current status updated to v1.1.7.
  • HISTORY_OF_HACK.md: replaced a misquoted struct monst with the verbatim original; fixed a misattributed Fenlason quote; Rogue trip dated to summer 1981 (per TIMELINE); custody dates and protoHack's role corrected; removed uncited sections (Dark Ages, Digital Archaeology, Technical Legacy, Philosophy, Conclusion).
  • TIMELINE/COMPARISON: READ_Me → READ_ME; 82-1 tape submitter and licensing wording corrected.
  • Package descriptions (CPack), CODING_STANDARDS, dev/README: Hack 1.0.3 is dated 1985; removed unsourced "94.2%/100% authentic" figures.
  • TODO: save-system plan marked as shipped in v1.1.5.
  • COMPARISON.md re-synced from protoHack after a source audit (line refs, counts, Hack 1.0 differences, stat-line survival, mechanics dated by the source).
  • HISTORY_OF_HACK.md: Hack 1.0 has 62 monster types; "unique" names corrected (wumpus survives as Hack 1.0's NOWORM fallback); mklev merged in 1.0.2.
  • TIMELINE: Harvey's account of sending JOVE to USENIX (jonmacs/jove#34); Bresnick vs Craddock on Jay's school year.
  • README: FreeBSD CI ran on Cirrus until its June 2026 shutdown; Linux and macOS are CI-tested on GitHub Actions.

Fixed

  • STABILITY: Shrinking the terminal below 80x24 mid-game exited without saving (check_resize() re-ran startup(), whose size check calls error()). The new term_getsize() re-reads the size via TIOCGWINSZ, and the game now waits on the "TERMINAL TOO SMALL" screen until the window is big enough; EOF there saves and exits through hangup(). (#21)
  • MEMORY: Save/restore leaks from the original code. save_engravings() dropped the engraving list without freeing it on every level save; dorecover() read the current level twice and leaked the first copy (monsters, objects, gold, traps, engravings, worm segments). Engravings are now freed as they're written, and the new freelev() frees the first copy before the reread. (#23)
  • MEMORY: savelev() cleared the worm segment lists without freeing them, leaking every worm segment on each level save (stairs, level teleport, S, and the level copies during restore); also in the original code. Segments are now freed as they're written.
  • STABILITY: enexto() hung when the nearest free square was 49 or more columns away: its xchar (signed char) loop counters wrapped past 127, so the scan never ended. Now int. (#38)
  • STABILITY: getlock() closed the lock file descriptor a second time when veryold() closed it and then failed to unlink a stale lock; the caller now owns the descriptor. (#32)
  • STABILITY: The lock name was copied from plname with the destination's size (35 bytes from a 32-byte array); now bounded by PL_NSIZ. Latent, as plname is always terminated. (#33)
  • STABILITY: freeobj()/freegold() dereferenced the list pointer before their NULL check could run, so a missing object crashed instead of reaching panic(); also in the original code. (#34)
  • STABILITY: RND() divides by zero for a modulus of 0; it now returns 0 for non-positive arguments. Latent: level generation never passes one (checked over 1000 seeds of every dungeon level). (#36)
  • CORRECTNESS: A nymph stealing cursed armor always said "you start taking" off: the curse bit was cleared before the message tested it; also in the original code. Now uses the saved value. (#35)
  • CORRECTNESS: hack.o_init.c declared bwrite()/mread() as int (int, char *, int), conflicting with their void (int, char *, unsigned) definitions (undefined behavior). (#30)
  • CORRECTNESS: safe_strcat()/safe_strcpy() (hack.objnam.c) rejected pointers outside an assumed 64-bit address range, which breaks on targets such as WebAssembly; now a NULL check only. (#30)
  • Removed a duplicated scrsym test in mpickgold()/mpickgems() introduced during modernization. (#37)
  • Help file: the diagonal directions were listed swapped (y: ne, u: nw, b: se, n: sw); the original 1985 file has the same error and is kept unchanged in docs/historical/. (#39)
