From an old bug report (sent directly to devteam, June of 2017):
wand or scroll of create monster becomes discovered if it makes
a mimic that is concealed as an object or as furniture within
the hero's view. Fixing this in the general case [when does
seeing a mimic as something other than a monster mean that the
mimic is being seen?] is a massive can of worms, but fixing this
specific case is trivial.
During hallucination, actions which triggered update of persistent
inventory made Qt's display of map tiles for equipped objects have
those tiles switch randomly, but ordinary move-by-move fluctations
applied to floor objects left them alone.
Initially I took out hallucination of inventory items altogether,
but ended up putting that back and changing the floor hallucination
to affect Qt's paper doll too. The display.h change isn't needed
but I've left it in.
Adds two monsters originally from slash'em. I used the slash'em
tiles this time, also its code as a starting point but made various
revisions. Both the tiles could benefit from some touch-ups.
displacer beast: blue 'f'. Attempting a melee hit (ie, trying to
move to its spot) has a 50:50 chance for it to swap places with you.
Fairly tough monster to begin with, then half your ordinary attacks
effectively miss and if you try to face a mob by retreating to a
corridor or backing into a corner you can end up being drawn back
into the open. I added bargethrough capability, and also it won't
be fooled about hero's location by Displacement. [It only swaps
places during combat when contact is initiated by the hero, not
when attacked by another monster or when attacking.]
genetic engineer: green 'Q'. Its attack causes the target to be
polymorphed unless that target resists. Hero will almost always
have magic resistance by the time this monster is encountered, but
it can make conflict become risky by hitting and polymorphing other
monsters. Slash'em flagged it hell-only but I took that flag off;
I also took away its ability to teleport. Slash'em polymorphs the
hero if a genetic engineer corpse is eaten; that's included and I
introduced that for monsters too.
I added both of these to the list of candidates for monster spell
'summon nasties' and for post-Wizard harassment.
I also gave all the 'f's infravision. Probably only matters if the
hero polymorphs into a feline.
Displacer beast is originally from AD&D which depicts it as a six-
legged cougar with a pair of tentacles; it has Displacement rather
be able to affect an attacker's location. I think genetic engineer
is original to slash'em where it expands Q class but seems mainly to
be the base monster for Dr.Frankenstein (a unique monster with a
one-level side-branch lair in slash'em's incarnation of Gehennom).
Switch win/share/*.c from hack.h to config.h plus miscellaenous
other headers. It's possible that there is conditional code that
didn't get exercised in my testing. The Unix Makefiles don't deal
with safeproc.c or tileset.c so I just compiled those without any
attempt to link.
Changes domove() code to allow displacing peaceful monsters.
Specifically, is_safepet() now returns true if the monster is peaceful.
Peacefuls are slightly pickier than pets about whether they consent to
being displaced: they will not displace if a goodpos() check fails for
the displaced space, or if there is a trap on the displaced space, or if
they are your quest leader. is_safepet should probably be renamed to
something else.
In the process of doing this, some other changes were made: the code now
checks whether the player and monster should be swapping places at all
first (previously it ran some code for displacing pets out of traps
first, which was a little weird if the displacement didn't actually
happen.)
In the original commit for this, I needed to guard the spoteffects()
call made in domove with a clause testing whether the player actually
moved; it was previously possible to fail to displace a monster and then
re-trigger a trap on the space you were still standing on. However, the
devteam has apparently put in an if (u.umoved) clause in the same place
and serving the same purpose.
This adds a pair of new glyphs: GLYPH_UNEXPLORED and GLYPH_NOTHING
GLYPH_UNEXPLORED is meant to be the glyph for areas of the map that
haven't been explored yet.
GLYPH_NOTHING is a glyph that represents that which cannot be seen,
for instance the dark part of a room when the dark_room option is
not set. Since the symbol for stone can now be overridden to
a players choice, it no longer made sense using S_stone for the
dark areas of the room with dark_room off. This allows the same
intended result even if S_stone symbol is mapped to something visible.
GLYPH_UNEXPLORED is what areas of the map get initialized to now
instead of STONE.
This adds a pair of new symbols: S_unexplored and S_nothing.
S_nothing is meant to be left as an unseen character (space) in
order to achieve the intended effect on the display.
S_unexplored is the symbol that is mapped to GLYPH_UNEXPLORED, and
is a distinct symbol from S_stone, even if they are set to the same
character. They don't have to be set to the same character.
Hopefully there are minimal bugs, but it is a deviation from a
fairly long-standing approach so there could be some unintended
glitches that will need repair.
Throwing or kicking a lit lamp, lit candle, or lit potion of oil
wasn't giving off any light as it travelled to its destination.
Now it does, and dungeon features, objects, or monsters that are
temporarily seen as it moves from square to square till appear on
the map. In the monster case, they go away as soon as the light
moves beyond range, but when it finishes moving the "remembered,
unseen monster" glyph will be drawn at their location. I think that
part has some room for improvement, but mapping temporarily seen
terrain features is the primary impetus for this change.
Also, any message delivery while the "lit missile" travelled still
showed its light around the hero. Noticeable for lamps or stacks
of sufficient candles if hero has no other light source.
This cannibalizes the monst->mburied bit for temporarily seeing a
monster. It has been present but unused for ages. I needed to
replace a couple of vision macros to make sure they didn't examine
it any more so that overloading for transient lighting doesn't
introduce any vision oddities. For version $NEXT, monst->mtemplit
can be given its own bit. It is only set during bhit() execution
and cleared by the time that returns, so has no effect on save files.
Preserve temporary fake object's previous dknown value by storing it
as a flag value within the m_ap_type field of the posing monster, and
recalling it when it is needed.
This is intended to help eliminate observable differences in price display
between real objects and mimics posing as objects.
98% of this is just switching the code to utilize macro M_AP_TYPE(mon)
everywhere to ensure that the flag bits are stripped off when needed.
This is based on the multiple-RNGs code fron NetHack4, but using
only the parts relevant to the display RNG (and with substantial
changes, both because of post-3.4.3 changes, and because Nethack4's
display code is based on Slash'EM's rather than NetHack's).
This adds many funny, realistic, and nonsensical traps to the game, to
be shown when the player is hallucinating.
Architecturally, the biggest change is merging the what_trap macro and
the "defsyms[trap_to_defsym(ttyp)].explanation" pattern into a single
function "trapname", which returns the name of the trap, handling the
hallucination case. There is also a second parameter used for overriding
hallucination in the occasional cases where the actual trap name should
always be returned.
In addition, the what_trap and random_trap macros are now obsolete and
not used anywhere, so they are removed.
The 'O' handling for bouldersym was updating the display value for
boulder even if the value had been rejected, and if it still had the
default of '\0', the map would end up with <NUL> characters. (When
examined via '//' or ';', those matched dummy monster class #0 and
led to the impossible "Alphabet soup: 'an("")'" that was suppressed
yesterday.)
Attempting to set bouldersym to ^@ or \0 would also be rejected as
duplicating a monster symbol. That is now accepted and used to reset
the boulder symbol to default. However, other control characters are
also accepted--not due to this patch, they already are, and from a
config file in addition to via 'O'--so bouldersym can still disrupt
the map. But that's no different from putting control characters
into a symbol set or setting them from config file via S_foo:^C.
A couple of macros with comments in the midst of their expansions got
badly mangled by the automated reformat and one ended up with a line
that was over 150 characters wide.
I did my best to exempt some of the bigger aligned blocks from the reformatting
using the /* clang-format off */ and /* clang-format on */ tags. Probably some
that shouldn't have been formatted were anyway; if you encounter them, please
fix.
The clang-format tags were left in on the basis that it's much easier to prune
those out later than to put them back in, and it means that, modulo my custom
version of clang-format, I should be able to run clang-format on the source tree
again without changing anything, now that Pat has fixed the VA_DECL issues.
I started out just to replace the weird partial expression in the
maybe_display_usteed macro but ended up cleaning up some other stuff
such as line wrapping.
There are still tabs present.
Remove the code that converted statues shown as monsters into stautes
shown as big rocks when saving and then reversed the effect when
restoring. It was done to preserve save file compatability with 3.4.3
where statue-as-monster glyphs didn't exist, so is no longer useful.

Sources tagged before applying NETHACK_PRE_STATUE,
and afterwards with NETHACK_POST_STATUE for easy
rollback.
Make the names of the macros for handling the hero be similar to those
for monsters (where mis-use of `sensemon()' was the cause of a recently
reported bug). `senseself()' becomes more restrictive in what it specifies,
and current uses of it are replaced by new `canspotself()'.

To that end...
- add a context (iflags in 3.4.3 to maintain savefile compat) flag to
differenciate the first travel step from later steps, to allow the
detection of the final sentence, above.
- several changes to set/reset the travel1 flag as needed
- add code to findtravelpath to treat the first step specially if it's
the only step, allowing forced travel into a "bad" location
- correct the "don't travel over traps" code, which was getting confused
because hero's starting location was being avoided
- add code to avoid traveling into water and lava, duplicating
checks used for non-travel running
- fix some strange "guess" travel behavior: avoid zigzag paths when there's
a more direct path (even though the number of moves is the same)
- trunk change adds a new DISP_ALL tmp_at type, and uses it in some debug
code for travel, debug changes not added to the 3.4.3 branch

This patch:
- collects all context/tracking related fields from flags
into a new structure called "context."
It also adds the following to the new structure:
- stethoscope turn support
- victual support
- tin support

- Version change from 3.4.x
- timed_delay feature ignore in makedefs
- several flags from iflags to flags
- use offsets from mons array entries in save file rather than storing
the ptr and calculating the distance from beginning of array
If the character was invisible without being able to see invisible,
his location on the map showed any object there or underlying topology
instead of the hero even when monsters could be seen with infravision,
ESP, or sustained monster detection. The ESP case required an amulet
or helm or quest artifact to be noticeable because being blind overrides
being unable to see invisible, so the more common form of telepathy
didn't exhibit this behavior.
Several flags added since 3.4.0 were destined for flags
(to be saved with the game) but were placed in iflags for
savefile compatibility. These include:
boolean lootabc; /* use "a/b/c" rather than "o/i/b" when looting */
boolean showrace; /* show hero glyph by race rather than by role */
boolean travelcmd; /* allow travel command */
int runmode; /* update screen display during run moves */
This patch has no effect unless you define this in your port's
XXconf.h file.
#define SAVEFILE_340_CONVERT /* allow moving of some iflags fields to flags
without destroying savefile compatibility */
Without it, the new flags remain in "iflags." With it, the flags are moved to
"flags" and the structures are converted when the save file is read. There
is no reverse compatibility. If you save the game after conversion, you
can't load the savefile on 3.4.0, only 3.4.1.
Replace "feature_toggle" implementation with an easier-to-understand
boolean option called "lootabc".
Provide "showrace", an option to display the hero by race glyph rather
than by role glyph.
Document the above.
Remove some obsolete Mac options.
