Previously, the code for monster healing was repeated every time it
was needed; this commit sends it all through a common function, which
will make it easier to make changes to how monster healing works in
the future.
This is just a code reorganisation and won't have any gameplay
effect unless I made a mistake.
We can't just unconditionally unblock vision for a location when a boulder
falls into a pool, because the location may also have a (poison) cloud on it.
gcc has recognized various "magic comments" for white-listing
occurrences of implicit fallthrough in switch statements for
a long time:
The range and shape of "falls through" comments accepted are
contingent upon the level of the warning. (The default level is =3.)
-Wimplicit-fallthrough=0 disables the warning altogether.
-Wimplicit-fallthrough=1 treats any kind of comment as a "falls through" comment.
-Wimplicit-fallthrough=2 essentially accepts any comment that contains something
that matches (case insensitively) "falls?[ \t-]*thr(ough|u)" regular expression.
-Wimplicit-fallthrough=3 case sensitively matches a wide range of regular
expressions, listed in the GCC manual. E.g., all of these are accepted:
/* Falls through. */
/* fall-thru */
/* Else falls through. */
/* FALLTHRU */
/* ... falls through ... */
etc.
-Wimplicit-fallthrough=4 also, case sensitively matches a range of regular
expressions but is much more strict than level =3.
-Wimplicit-fallthrough=5 doesn't recognize any comments.
Plenty of other compilers did not recognize the gcc comment convention,
and up until now the compiler warning for detecting unintended
fallthrough had to be suppressed on other compilers. That's because the code
in NetHack has been relying on the gcc approach, and only the gcc approach.
The C23 standard introduces an attribute [[fallthrough]] for the
functionality, when implicit fallthrough warnings have been enabled.
Several popular compilers already support that, or a very similar attribute
style approach, today, even ahead of their C23 support:
C compiler whitelist approach
--------------------------- -------------------------------------
C23 conforming compilers [[fallthrough]]
clang versions supporting
standards prior to
C23 __attribute__((__fallthrough__))
Microsoft Visual Studio
since VS 2022 17.4.
The warning C5262 controls
whether the implict
fallthrough is detected and
warned about with
/std:clatest. [[fallthrough]]
This adds support to NetHack for the attribute approach by inserting a
macro FALLTHROUGH to the existing cases that require white-listing, so
other compilers can analyze things too.
The definition of the FALLTHROUGH macro is controlled in include/tradstdc.h.
The gcc comment approach has also been left in place at this time.
This is additional groundwork related to
https://github.com/NetHack/NetHack/issues/1320
This additional groundwork just puts some safeguards
in place to make it rather tough to end up with an
instant death from handling a cockatrice corpse in
your inventory without appropriate protection.
At this point, still no actual petrification will occur.
'Polyfodder' is already a term frequently used by players to describe
items which are useful to hang on to specifically to zap polymorph at
(for example, extra unicorn horns, which can be turned into magic
markers). Using it as the name of a macro which tests whether a food
item will polymorph the creature consuming it is somewhat confusing, and
I think 'polyfood' is a lot clearer.
The g? structs had a mix of variables that were written to
the savefile, and those that were not.
For better clarity and to distinguish those that end up in
the savefile, relocate some g? variables that get written
directly to the savefile into different structs.
This updates EDITLEVEL, although technically it probably
didn't need to, since savefile contents are not changing.

There are some pointer variables that are heads of chains that were not
moved from 'g?' to 'sv?', because they are not actually written to the
savefile directly, but the objects/monst/trap/lightsource/timer in the
chains they point to are. That can be changed, if desired.

A pet titan dropped a boulder over a pool, and the code killed
the titan, because the code was considering the titan to be in
the water.
If a flyer or a floater is over the pool, don't kill them off
if a boulder is dropped in there. Also make the pet movement
code handle the case where the pet might've died while dropping
items.
Adds a new boolean option, spot_monsters. If on, every time
the hero notices a monster which was out of sight before,
a message is given. Combine with accessiblemsg to get the
monster location:
(3north): You see a newt.

- set memory and step limits on all Lua VMs
Pull request from entrez: in the class filtering menu for multi-drop
and for loot in-or-out of a container, make choosing 'A' without any
other filter choices (such as all, specific class(es), cursed, unpaid,
just-picked-up, &c) become a no-op.
I started with the pull request and then undid much of it. It would
have been simpler to start from scratch. If you don't have option
paranoid_confirmation:AutoAll set, when choosing 'A' for all-without-
prompting as the only selection, operate as the PR has made things
work: effectively, 'A' by itself is ignored and the operation ends
with nothing happening.
However, if you do have paranoid_confirm:A set, then continue treating
'A' by itself as if 'A'+'a': everything. Since paranoid confirmation
is specified, that will be followed by a confirmation prompt.
This also adds a context-sensitive hint to the menu about how the 'A'
entry works, shown every time when 'cmdassist' is On or just once (per
session) when that is Off.
The documentation probably needs some updating.
Closes#1143
The 'A' option in the #loot or 'D'rop menu selecting every selectable
item when used on its own has been the cause of many bag of holding
explosions and other typo-related frustration. Now that it operates on
other filters rather than overriding them, actually require some other
filter be selected for it to have any effect. This means that 'A' on
its own will do nothing, but 'A'+'a' will still act like 'A' alone
previously did. I think this will reduce the rate of serious typo
accidents in games, without being intrusive and while still maintaining
'A' as a useful option (which I think it is, in it's 3.7 incarnation --
I use it all the time in combination with other filters, especially
justpicked).
Add pickup_stolen option to autopick items stolen from you by a nymph or
monkey, even if they don't match your normal autopickup settings.
Replace was_dropped, was_thrown with a 2-bit bitfield that can contain
values LOST_DROPPED, LOST_THROWN, and LOST_STOLEN (or 0), since they
should all be mutually exclusive anyway as they track the most recent
way the item left the hero's inventory.
[Rebase/merge conflict fixed up. PR]
This is based on a feature in UnNetHack (and I think some other variants
as well). If the hero intentionally drops an item with 'pickup_dropped'
disabled, don't autopick it back up when walking over that square again.
Typically when the player drops an item, it's because she doesn't want
it in her inventory any more, and this option stops autopickup from
defeating that goal (especially useful for tasks like stash management
without a container). Players have come up with workarounds to this
problem like toggling autopickup when approaching their stash pile or
adding name-based autopickup exceptions to allow them to exclude
individual items from autopickup, but this behavior should reduce the
need for those things.
I think 'pickup_dropped' is a little unfortunate because it suggests
equivalence to 'pickup_thrown' (i.e. any dropped items will be
automatically picked up regardless of autopickup exceptions). Calling
it something like 'nopick_dropped' might be better, but as far as I can
tell options cannot start with the word 'no' because it's interpreted as
a negation of the rest of the option name.
Fixup some of the inconsistently formatted code that has been
introduced recently or been building up for a while. Done manually.
I wasn't systematic except for looking for lines ending in '&' or '|'
(which wouldn't find such things if they're followed by a comment)
so there might be lots more. I changed a bunch of C++-style //...
comments to old style C /*...*/ so that they'll match the rest of
the core's code rather than because they shouldn't be used.
The tracks left by hero were cleared when player saved and
restored the game, or changed levels. Now the tracks are
saved in the dungeon level, so changing levels keeps the tracks
left by hero in that level.
Also increased the length of tracks from 50 to 100, and
simplify the tracking function.
Thing not done: fade out old tracks when returning to a level.

As such, it shouldn't be affected by the heat of the ground in
Gehennom (which is hot enough to boil but not to burn). The oil
still heats but won't break its bottle.
In Gehennom and on the Plane of Fire, the ground is hot enough to
boil potions (although not hot enough to, e.g., burn scrolls).
The potions sometimes survive this (almost always if it's your
potion, it's blessed, and you have maxed Luck), but often don't.
In addition to making a lot of flavour sense, this serves a
gameplay purpose in that it reduces the number of potions that
are deathdropped by monsters in the late game. In Gehennom,
monsters often generate with potions to use defensively, but then
get killed before they have a chance to use them: this produces a
surfeit of potions that players tend to convert into holy water or
potions of full healing (and in general it doesn't make much sense
that the basic potion of healing primarily generates in Gehennom).
This commit approximately halves the number of useful potion
deathdrops, whilst still allowing monsters access to their
potions; when the monster dies, it drops the potion and this has a
chance of destroying it.
Sometimes I annotate a level with a note like "watch out, chameleon
below", which is useful to remind myself of some danger or thing to
remember when returning to the level -- but if saving and restoring on
the level itself there's no reminder of that annotation. If you restore
on a level with an annotation, print it as part of the "welcome back"
message.
This is largely taken from xNetHack with a few minor changes. Dipping a
potion into a sink can help with item identification by producing the
potionbreathe effect (or a sink-specific effect, for a couple potions).
Dipping other items will just run water over them. I also added the
capability to wash your hands at a sink.
Change 852f8e4 by requiring a minimum impact before a buried zombie
nearby will be disturbed: light, but still excluding things like
scrolls, if it's a violent impact (dropped while levitating, thrown, or
kicked), and fairly heavy if the hero is just placing the item on the
ground normally.
Moving the call out of flooreffects meant it no longer applied to
pushing boulders around, so have moverock disturb nearby zombies. I
additionally had wake_nearby do the same thing.
Finally, I renamed check_buried_zombies (which doesn't really reflect
what it does) to disturb_buried_zombies.
When returning to play from within the tutorial, remove the level files
similar to how they're discarded for the rest of the dungeon when going
into the endgame. It turned out to be a bit messier than anticipated.
The dungeon.c bit is sufficient for #overview, which now hides regular
level 1 while in the tutorial and hides all tutorial levels once exited.
Those will still appear in end-of-game disclosure.
I was looking to see what the impact of converting glyph_to_cmap() to
a function might have and noticed a couple of places where the macro
edition is passed a non-trivial argument. Since it evaluates that
argument many times, there is hidden overhead. Fetch the glyph once
and pass that to glyph_to_cmap().
This will no longer be very useful--but won't need to be reverted--if
PR #1022 gets incorporated.
do_positionbar() has bugs (only matters for MS-DOS).
This replaces most of commit 0ca2af4d8b
from a couple of days ago with something more robust. That change
actually introduced redundant code that caused fountain and/or sink
count to be off instead of preventing it.
Revise set_levltyp() to update level.flags.nfountains and
level.flags.nsinks if setting the type to or from fountain or sink.
A bunch of places that were setting levl[x][y].typ directly needed
to be revised to use set_levltyp() instead. set_levltyp() itself
hadn't been updated to handle LAVAWALL (to force such to be lit).
Replace tests against tutorial_dnum with 'In_tutorial()' predicate.
Give a message when entering the tutorial (via level change mechanism).
Likewise, give a message when resuming regular play.
If player uses #quit or ^C in the tutorial, ask whether to cut the
tutorial short and resume regular play; skip "Really quit?" if the
answer is yes. Behavior is a bit odd for ^C + yes; it just sits there
until player types something.
Reported by Noisytoot: going from level tut-1 to tut-2 returned the
hero's starting equipment too soon, and exiting the tutorial from
tut-2 let the hero keep any equipment acquired within the tutorial.
Entering and leaving the tutorial was being handled by lua code in
the level description of tut-1 and adding a second level messed that
up. I didn't see any way of handing that with level-specific lua
code so I made it become the core's responsibility. gotolevel()
knows when the hero is moving from one dungeon branch to another so
it can recognize entry to or exit from the tutorial easily.
While fixing this, prevent #invoke of the Eye of the Aethiopica from
offering the tutorial as a candidate destination (was feasible if it
had been entered at start of game).
Not fixed: levels visited in the tutorial become part of #overview.
Show location as "Tutorial:1" instead of "Dlvl:1" on status lines.
Only tested with tty; some interfaces handle location themselves and
may need their own fixup for this.
Fixes#1046
Reported by copperwater: entering the tutorial sets 'u.nofollowers',
changing to the tutorial level saves a copy of 'u', post-level change
from entering the tutorial level resets u.followers, but subsequently
changing levels to return to the original level 1 restores 'u' from
the saved copy with has 'u.nofollowers==True', overriding the reset.
Move the nofollowers flag from 'u' to 'iflags'. Invalides save and
bones files.
Fixes#1027
