SIMud, an Apache-2.0 English LDMud-style mudlib by Allaryin, Acius, Venger, and Malap. LDMud → FluffOS conversion: archive master uses set_driver_hook and closures. Strategy A login lands in the Temple of All Gods (Oldtown spawn); the saved world.obj tree is not in the snapshot. Not StickLib or Age of Elements.

Authors: Allaryin, Acius, Venger, Malap (Apache 2.0). Full mud/ tree preserved; interactive play here is the Temple of All Gods start (hall + Oldtown street). Published as playable on that start.

Registration flow

Name (2–16 letters) → new character: password (≥6, twice) → Temple of All Gods. Existing names prompt for password only.

SIMud (simud) — porting notes

Source: git clone https://github.com/shentino/simud (commit 644b7d4f56bf8d4695442b8efcfd56e0a561fe21, cloned 2026-09-05); mudlib root is mud/. Converted 2026-09-05. Config name SIMud. Slug simud, number 978, port 40287.

This is an LDMud → FluffOS conversion. Discovery triage normally drops LDMud-lineage libs; this onboard is an explicit exception in the same family as questmud / acme (AGENTS.md §7.158).

This collection’s copy is a snapshot, not a live mirror. Do not onboard the same upstream repo again.

0. Layout

Repo root is the mudlib. raw/ is gitignored. Original LDMud master preserved as /secure/master_ldmud.lpc.

1. Convert (2026-09-05)

convert_lib.sh with UTF-8 source encoding (already UTF-8 English / German sources). .c → .lpc rename + literal .c" fixups + static→nosave as usual.

2. FluffOS port (LDMud → FluffOS)

The archive is LDMud 3.x (set_driver_hook, inaugurate_master, #' / unbound_lambda closures, multi-file or directory simul_efun). FluffOS has none of those driver hooks. A mechanical dialect rewrite of the whole tree is not attempted; the original login/command stack is kept as source and not loaded.

config.fluffos: master /catalog/master, simul /catalog/simul_efun, global include "/catalog/auto.h", port 40287, lazy resets : 1.

Catalog overlay (questmud §7.158 cluster):

/catalog/master.lpc — get_root_uid/get_bb_uid, creator_file always returns string "BACKBONE", valid_read includes load_object/recompile_object/include/restore_object, valid_override returns 1, error_handler → /log/catch
/catalog/simul_efun.lpc — thin cat/log_file/exists
/catalog/login.lpc, /catalog/player.lpc — name/password → Void
/catalog/void.lpc, /catalog/workshop.lpc — look/score/quit surface

3. Live-verified (native, port 40287)

Create fluffos / Mud@2026. Lands in The Void; look / score / north (workshop) / south / quit. Reconnect after cold restart reloads data/f/fluffos.o.

深度功能测试（§10.7, 2026-09-05）

Catalog overlay only — rooms/races/magic/economy under the mud/ tree are not loaded. Organic fluffos / Mud@2026 on native 40287: Void look / score (level 1, hp 20/20) / inventory / north workshop / south / quit persist. Reconnect: Void look / score / quit. Shop, combat, guild, death: N/A (needs a real LDMud driver).

Logs this boot (PID started 20:09:43, live fd libs/simud/log/debug.log): stdout + debug.log clean. work/log/catch proven live with a one-shot catchprobe (CAUGHT /catalog/player.lpc *catch-path-probe) then reverted; play itself left no other catch lines.

6. Full dialect port (Strategy A, 2026-09-06)

Catalog Void/workshop is no longer the live start. User asked for the real SIMud spawn, not a demo skeleton.

The archive spawn is ;ch;oldtown;temple;temple2 ("Temple of All Gods"). SIMud's world is a saved object tree (/world/world.obj); that dump is not in the git snapshot. Strategy A reconstructs the spawn path as FluffOS rooms under /world/start/:

/world/start/temple2 — inner shrine (login)
/world/start/temple — public hall
/world/start/oldtown — street outside

/catalog/login still handles name/password. /catalog/player enter_world() moves into temple2 (fallback Void if load fails).

Live walk (native 40287, 2026-09-06, organic fluffos / Mud@2026):

Lands in Temple of All Gods. look at altar.
North → temple hall. North → Oldtown street (further streets closed). South ×2 back to the shrine.
score level 1, hp 20/20. Quit persist. Reconnect lands in the shrine again.

This-boot live libs/simud/log/debug.log (fd, PID 1693124 BOOT_MARKER1 simud-temple): start rooms compiled. Catch this walk: empty after the marker.

Published (wasm_status: playable) after user 2026-09-11: they can consider playable now. Temple / hall / Oldtown street is the snapshot start. The rest of Oldtown still lived in world.obj — do not invent streets. Shop / combat / guild are not in those rooms.

4. What is not ported yet

Full LDMud world object tree (no world.obj in the snapshot), guilds, protocol stacks, OSB/MG kernel daemons, shop, combat. Original /world/room uses LDMud closures ((: $1->… :)). Next simud slice: more Oldtown if we can reconstruct it from archive files (not by inventing streets). Published as playable on the existing start.

Leftover 634 (2026-09-10, cheap reconfirm, no boot). find still has no world.obj. Walkable start is still the three reconstructed rooms under /world/start/ (temple2 / temple / oldtown). Oldtown is south-only (“further streets are closed”). Shop / combat / guild are not in those rooms. Do not invent Oldtown. Do not flip. aoh is already playable (29d73abf400).

Leftover 635 (2026-09-10, persist only, no boot). Same tree as leftover 634 (f0975b36b09): no world.obj; start still temple2 / temple / oldtown. Do not invent Oldtown. Do not flip.

Leftover 636 (2026-09-11, persist only, no boot). Same tree as leftover 635 (1ddf6f10123): no world.obj. Do not invent Oldtown. Do not flip.

Leftover 637 (2026-09-11, persist only, no boot). Same tree as leftover 636 (d60cd9919c7): no world.obj. Do not invent Oldtown. Do not flip.

Leftover 638 (2026-09-11, persist only, no boot). Same tree as leftover 637 (3dcd14f5af3): no world.obj. Do not invent Oldtown. Do not flip.

Leftover 639 (2026-09-11, persist only, no boot). Same tree as leftover 638 (b7106c81e28): no world.obj. Do not invent Oldtown. Do not flip.

Leftover 640 (2026-09-11, persist only, no boot). Same tree as leftover 639 (16876edf6d8): no world.obj. Do not invent Oldtown. Do not flip.

Leftover 641 (2026-09-11, persist only, no boot). Same tree as leftover 640 (f89c13266ea): no world.obj. Do not invent Oldtown. Do not flip.

Leftover 642 (2026-09-11, persist only, no boot). Same tree as leftover 641 (25e2370fa27): no world.obj. Do not invent Oldtown. Do not flip.

Leftover 643 (2026-09-11, persist only, no boot). Same tree as leftover 642 (7860bad89b1): no world.obj. Do not invent Oldtown. Do not flip.

Leftover 644 (2026-09-11). User: they can consider playable now. Flipped wasm_status to playable on existing temple / hall / Oldtown evidence. Do not invent Oldtown. world.obj is still missing.

Leftover 645 (2026-09-11, persist only, no boot). Already playable (546d780ee87). Same tree: no world.obj. Do not invent Oldtown. Do not flip again.

Leftover 646 (2026-09-11, persist only, no boot). Already playable (546d780ee87). Same tree as leftover 645 (bfcd764dde2): no world.obj. Do not invent Oldtown. Do not flip again.

Leftover 647 (2026-09-11). User: source-complete is done; do not invent. Start rooms still have no extra archive objects; rest of Oldtown lived in world.obj. Do not invent streets.

Deep test (§10.7, 2026-10-08) -- fixed-width `.lpc` suffix slices

The .c -> .lpc rename changed the string but not the slice width: f[<2..] == ".lpc" compares two characters with four and is never true (!= always true), so suffix filters and strips never ran or cut x.l (KB 06 §7.238). scripts/lpc_lpc_suffix_slice.py --apply fixed 6 comparison(s) and 2 strip(s) (e.g. bin/wiz/clone.lpc); the changed files load at HEAD and in the tree (fresh processes) with no regression.

2026-10-10：编译警告第二轮（按驱动报告逐条修）：按位 & 改逻辑运算 0 处，返回类型/原型 0 处，NPC+F_UNIQUE 的 init() 0 个，带初始化的未用局部变量 31 个，只在 #if 分支用的声明移进分支 0 个文件；改动 25 个文件，HEAD 与工作树各载入一次无回退（15 objects; HEAD PASS 3, tree PASS 3; regress 0; newly loading 0），这些文件的警告 39 -> 19。

2026-10-10（续）：第二轮编译警告整理误改了 test/quote.lpc 测试文件，已恢复原样。

Compile warnings (2026-10-13)

scripts/toolkit_fix.sh round: bare return; in int functions became return 0; (the driver already returned 0), unused locals were removed, and the LDMud-only pragmas FluffOS does not know (#pragma strong_types, no_clone) were dropped. By hand: a stray ; after the class body in include/legible.h. No warnings left in compiling files except one in test/quote.lpc, a test file left as is. The 46 changed objects load the same at HEAD and in the tree (regress 0).

2026-10-14 (FluffOS 970d9f09 rescan): test/quote.lpc drops a local it never used (the macro test only stringifies the literal "x"). The file loads.

2026-10-14: 1 files did not compile with Type of returned value doesn't match function return type ( int vs void ): a function declared void (or with no type) returns a value, which the old driver passed to the caller. Functions whose value a caller reads (add_action handlers, commands, helpers) now carry the type they return: on_action(). HEAD vs tree in fresh drivers: 1 objects, 0 newly loading, 0 regressions (scripts/lpc_fix_void_return.py, KB 04 §6.3).

`sizeof(x == n)`: the comparison inside the parentheses (KB 06 §7.350, 2026-10-21)

sizeof(tmp != 2), sizeof(casualties ==1), sizeof(arr==1), sizeof(file_list == 0) evaluate the comparison first and take sizeof() of the 0 or 1 it gives (sizeof(1) is 0 in this driver), so the guard or message branch never runs; in the poker dealer, where hand is string *, the typed comparison is a compile error and the dealer never loaded. Rewritten as sizeof(x) == n. Left alone: /std/living.lpc and /std/user.lpc query_prestige_level(), /std/living/body.lpc "one handed" (the same typo, but enabling the branch changes class and weapon rules). Changed: /bin/wiz/mv.lpc.

`log/` subdirectories nobody created: the logging `write_file()` / `log_file()` raises (2026-10-22, KB 06 §7.358)

The code of this lib writes logs into 2 subdirectories of log/: log/chat (daemon/chat.lpc), log/comm (obj/newplayer.lpc). Neither the archive, a git clone nor the site pack has them (no local boot wrote into them, so gen_keep_dirs.py never recorded them), and write_file() raises *Wrong permissions for opening file /log/dlog/money for append. "No such file or directory" for a missing directory: the function that logs stops on that line and what came after it (the reward, the flag, the next step) never runs. This lib's log_file() is write_file(LOG_DIR + file, text) and raises the same error for a missing directory (measured). log/chat, log/comm are now in scripts/wasm_keep_dirs.txt (scripts/lpc_keep_log_dirs.py; the site and the pristine tree create the empty directories from it). Proof (scripts/lpcc_eval.py, an eval object under /adm/daemons or similar writes /log/zzdirprobe/..., fresh processes): the measured table in KB 06 §7.358.

深度功能测试（2026-10-27，§6.25 LDMud foreach 冒号）

与 sticklib 同形：foreach (T x : arr) / foreach (k, v : map) 改为 in（约 291 文件 / 677 处）。证明：HEAD /ai/beast 因冒号失败；改后加载。

深度功能测试（2026-10-27，§6.10 LDMud 未知 pragma）

master_security.lpc / world.lpc 的 LDMud-only pragma 已删。

深度功能测试（2026-10-27，§6.25 LDMud `#'fn` 闭包）

同 sticklib：#'ident → (: ident :)（跳过 #'? / 'symbol 行）。

深度功能测试（2026-10-28，remove_call_out 闭包→字符串）

telnet_ob 的 remove_call_out((:timeout:)) 改为字符串。
