Commit 1acc2727 helped ensure that the which_armor(mtmp, W_SADDLE)
test at the top of put_saddle_on_mon() wouldn't lead to an obj
leak.
This commit covers off the adjacent can_saddle() test in
put_saddle_on_mon(), because if that failed, it could also lead
to a memory leak of the saddle obj passed by the caller.
- have put_saddle_on_mon() create and use its own saddle obj
if a NULL saddle obj is passed, instead of having to do that
in the caller.
- where an existing saddle obj needs to be passed from the caller,
ensure that the caller has done its own can_saddle(mon) check prior
to calling put_saddle_on_mon(), so that the can_saddle() test
in put_saddle_on_mon() won't fail.
- lastly, add an impossible() to put_saddle_on_mon() to catch
a failure when a saddle obj is passed from the caller and either
test has failed, just in case. That should not happen with any of
the existing cases now, but it will provide some bullet-proofing
for new code, new callers.
- Add a vision sanity checking routine
- Recalc block point when digging a door for temporary clouds
- Add recalc_block_point after cvt_sdoor_to_door, because doorways
on the Rogue level have no doors, and otherwise the sanity checking
would complain. This doesn't actually change how the Rogue level
vision works, as it uses a different vision system
- Monster using a trap in a secret corridor revealed the corridor,
but didn't unblock the vision unless you saw the location
Merge the recent change in the effect of blessed scroll of taming on
already tame monsters with the earlier change of any taming on already
tame monsters. Non-blessed has a chance of boosting monst->mtame by 1
when it is less than 10, more likely the lower the current value is.
For blessed, boost by 2 after that, so possibly by 3 if it is very low.
Make spell of charm monster when skilled or expert in enchantment
spells behave the same as blessed scroll of taming. [I'm not too sure
about this; it may make the spell too powerful.]
GitHub issue #1315 points out that it is possible for
a downstream function to change an object's nobj field
to point to a completely different chain.
The cited example by @vultur-cadens was:
for (obj = gi.invent; obj; obj = obj->nobj)
if (obj->oclass != COIN_CLASS && !obj->cursed && !rn2(5)) {
curse(obj);
++buc_changed;
}
curse() drops the weapon with drop_uswapwep(),
which calls dropx(),
which calls dropy(),
which calls dropz(),
which calls place_object().
place_object alters the nobj pointer, to point to the floor chain:
otmp->nobj = fobj;
fobj = otmp;
The result was that the next loop iteration was then using floor
objects from the floor chain.
This alters several for-loops to use a more consistent approach,
particularly when the obj is being handed off to a function,
where a downstream function might, or might not, alter the nobj
field.

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.

Related note:
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.
Examples: gi.invent, gm.migrating_objs, gb.billobjs, gm.migrating_mons,
gf.ftrap, gl.light_base, gt.timer_base
Using #invoke on wielded or carried Sunsword and picking direction
'>' or '<' lights the hero's spot. But setting levl[u.ux][u.uy].lit
was too simplistic. Lighting on the Rogue Level operates on full
rooms when done inside a room and doesn't to anything with done in a
corridor.
litroom() gave inappropriate messages in a couple of special cases.

Adds a new extended command #lookaround, which will describe
the map around the hero they can see or remember.
Adds a new boolean option mention_map, which will give a message
when an interesting map location in sight changes.
Simplify the valid-position highlighting via '$' by combining the
tmp_at(start) and tmp_at(populate) steps.
Add highlighting for a couple of targetting operations that would
give valid/invalid feedback via autodescribe but weren't displaying
highlight markers for $.
I made several jumping changes, most of them dealing with picking
hero's own spot.
src/read.c(2889): warning: Dereferencing NULL pointer 'sobj'.
The analyzer doesn't know that the one caller that passes a NULL
sobj argument, angrygods(), checks !Punished before doing so.
Use a NULL guard before dereferencing sobj so that it doesn't
matter anyway.
I didn't like "your hands begin to glow red even more" very much (the
hero's hands aren't really 'beginning' to glow if they already have an
active confuse monster effect, and "glow red even more" was an awkward
turn of phrase on top of that). Rephrase it to "The red glow of your
hands intensifies."
I used ^G to create a monster and specified "invisible owlbear". I
then got "An owlbear appears next to you." Except it didn't; it was
invisible and I lacked see-invisible. I imagine that newsym() was
called for the new-yet-invisible monster, but that remained buffered
and was gone overridden by the time pending map update got flushed
at some point after the monster was made invisible.
Add a new makemon() flag to turn a newly created monster invisible
during its creation, before "monster appears" message is delivered.
Since that message will now be suppressed in this situation, use the
cursor-flash hack that indicates where the new, unseen monster got
placed. Creating "1000 invisible <mon>" is something you probably
won't do twice.
At either of the genocide prompts,
|What type of monster do you want to genocide?
or
|What class of monsters do you want to genocide?
answering "?<return>" will show the list of monster types that have
already been genocided, then re-prompt.
Issue reported by vultur-cadens: changing helm of brilliance to
crystal made it stop being classified as "hard helmet" so it gave
less protection against things falling onto the hero's head.
Change the is_metallic() tests used on helmets to new hard_helmet().
Unlike when thrown, crystal helmets don't break when objects fall
on them.
Fixes#1060
Heroes recognized unseen same-race monsters by voice, but it yielded
an unexpected result if the monster was unique. Change it so that
hero will recognize any type of monster by its voice if that monster
has been seen and limit unseen same-race ones to non-unique monsters.
Treats shopkeepers as unique since they have distinct names.
This adds a new flag to struct monst in order to track whether each
specific monster has ever been seen or sensed.
relocate surface(), ceiling(), and avoid_ceiling() to dungeon.c
adjacent to has_ceiling() etc.
astral and fire, like airlevel and waterlevel return FALSE
for has_ceiling()
if a caller does happen to call ceiling() on fire level,
return "flames above"
if a caller does happen to call ceiling() on quest level,
return a more-generic "expanse above", instead of the
word "ceiling"
add "stairs" return to surface()
remove recent update to engrave.c to special-case "stairs"
since surface() will return that now
sound_verbal(char *text, int32_t gender, int32_t tone, int32_t vol,
int32_t moreinfo);
-- NetHack will call this function when it wants to pass text of
spoken language by a character or creature within the game.
-- text is a transcript of what has been spoken.
-- gender indicates MALE or FEMALE sounding voice.
-- tone indicates the tone of the voice.
-- vol is the volume (1% - 100%) for the sound.
-- moreinfo is used to provide additional information to the soundlib.
-- there may be some accessibility uses for this function.
It may be useful for accessibility purposes too.
A preliminary implementation has been attempted for macsound to test
the interface on macOS. No tinkering of the voices has been done.
Use of the test implementation requires the following at build time with make.
WANT_SPEECH=1
That needs to be included on the make command line to enable the test code,
otherwise just the interface update is compiled in.
I don't know for certain when AVSpeechSynthesizer went into macOS, but older versions
likely don't support it, and would just leave off the WANT_SPEECH=1.
If built with WANT_SPEECH=1, the 'voices' NetHack option needs to be enabled.
It was a bit strange, when I first started up the test, to hear Asidonhopo,
the shopkeeper, talking to me as I entered his shop and interacted with him.
Insert the calls to trigger a number of potential soundeffects
into the core.
If no additional soundlib support is integrated into the
build, then the Soundeffect macro (sndprocs.h) expands to nothing:
[#define Soundeffect(seid, vol)
]
If, however, at least one additional soundlib support is integrated
into the build, then the Soundeffect macro gets defined as this
in sndprocs.h:
[#define Soundeffect(seid, vol) \
do { \
if (!Deaf && soundprocs.sound_soundeffect \
&& ((soundprocs.sndcap & SNDCAP_SOUNDEFFECTS) != 0)) \
(*soundprocs.sound_soundeffect)(emptystr, (seid), (vol)); \
} while(0)
]
That macro definition checks for the hero not being Deaf; it checks
to ensure that the active soundlib interface has a non-null
sound_soundeffect() function pointer; and it checks to ensure
that the active soundlib interface has declared that it supports
soundeffects by setting the SNDCAP_SOUNDEFFECTS bit in its sndcap
entry. That just means that the interface routines are prepared to
accept and deal with the calls from the core, whether or not it
actually produces the desired soundeffect.
A number of C compiler suites have a math.h library that includes a yn()
function name that conflicts with NetHack's yn() macro:
"The y0(), y1(), and yn() functions are Bessel functions of the second kind,
for orders 0, 1, and n, respectively. The argument x must be positive. The
argument n should be greater than or equal to zero. If n is less than zero,
there will be a negative exponent in the result."
At one point, isaac64.h included math.h, although that has since been removed.
Some libraries used in NetHack (Qt for one) do include math.h and that required
build work-arounds to avoid the conflict.
Rename the NetHack macro from yn() to y_n() and avoid the math.h conflict
altogether, eliminating the need for that particular work-around.
