5e79d10377 wizard mode level teleport (trunk only)
Responding with '?' to the "what level?" prompt when using ^V in
wizard mode brings up a menu of special level destinations that lets you
move across dungeon branches.  But getting in and out of Fort Ludios
didn't work, and jumping to the endgame forced you to arrive on the Plane
of Earth.  Now Fort Ludios will not be selectable in the menu until after
the portal ordinarily used to reach it has been created (so you'll need a
level between Bigroom and Medusa with a vault on it to be created before
you can bypass the magic portal and jump directly to the Fort), and you
can go directly to any of the elemental planes, including Astral, without
stopping at Earth first (the Wizard will be there to greet you, whichever
level you pick).  Also, this limits the menu to endgame entries once you
are in the endgame.  (Previously, picking a non-endgame level would yield
"you can't get there from here"; you can still get that, if you really
want to see it for some reason, by giving a destination level number
outside the range of -1 to -5 instead of using the menu.)

     I hadn't realized that this feature has been around since 3.4.2 until
I couldn't find any new feature entry for in the current fixes file....

8370782a13 chameleon/genocide fix (trunk only)
While testing some pending teleport changes, I was baffled by having
my adjacent pet sometimes vanish when accompanying me on a level teleport.
Tracing through parts of execution:  keepdogs() kept it; losedogs() called
mon_arrive() which called place_monster() for it, but then right after that
kill_genocided_monsters() removed it.  Turns out that `kill_cham' was left
uninitialized for the first iteration through the fmon loop (and pet had
always just been inserted as first entry of the fmon list).

     No fixes entry; this revises a post-3.4.3 revision.

6ef8efcefb digging conjoined pits (trunk only)
This one turned out to be more effort than I had
originally anticipated.

We had a bug report requesting that zapping a wand of digging
laterally while in a pit should dig beside you. That seemed
like a reasonable enough request, but this ended up with
the following results:
- needed to check where this should not be permitted, or at
  least where there should be special-case code because there is
  something such as furniture on the surface above the dig
  point.
- now tracks conjoined pits through new fields in the trap
  structure, hence the pathlevel increment. The array of
  8 boolean values represents each of the 8 directions
  around a pit.
- Previously, pits could be adjacent to each other as two
  individual pits, in which case moving between them
  results in a fall as you went into the next pit. That
  behavior is preserved.
- Pits created either by zapping a wand of digging
  laterally while in a pit, or by "clearing debris"
  between two adjacent pits via a pick-axe, sets the
  conjoined fields for those two pits. You cannot
  create a brand new adjacent pit via pick-axe, only
  with the wand.
- The hero can pass between conjoined pits without
  falling.
- dighole() was hijacked for adjacent pit digging,
  so the ability to pass coordinates to it and
  its downstream functions was added (dig_up_grave()
  for example). dighole() does pretty much everything
  appropriately for this adjacent digging, more so
  than calling digactualhole() directly.
- moving into a conjoined pit that has spikes still
  does damage, but less so that "falling" into the
  spiked pit, and you "step on" the spikes rather
  than falling into them.
- Not done: should pits with the conjoined fields
  set be referred to as 'trenches' rather than pits
  in messages and identifications?

3299e318ca digactualhole() bit
I'm pretty sure this check at_u should be included since x,y
can be passed to digactualhole().  The lack of any related
bug reports suggest that at_u is currently always
true for any code that calls digactualhole().

e1ef0f1042 filling antholes
From a bug report:  when creating a
level, anthole rooms can be generated even when no ants are left, unlike
beehives which get suppressed once killer bees are gone.  Also, if some
ants are available but the type chosen for the current level isn't (in his
case, soldier ants had been genocided), the anthole was filled will random
monsters instead of picking another type of ant.  This fixes both issues.
Random monsters will only occur if the last type of ant gets used up while
filling an anthole that was started when some ants were available, same as
how monster generation for beehives and barracks works.

passes wand type to explode() as a negative value for the case
where the wand type isn't mapped to an AD_* explosion type.

Then explode() converts it to a positive and passes it to zap_over_floor().

00cd943aae minor scroll overhaul (trunk only)
The recently revised scroll of charging left out making it become
discovered.  When fixing that I decided to remove all the early returns
from seffects(), so that its logic is easier--at least for me--to follow.
I think the return values of seffects(), chwepon(), and the various
xxx_detect() routines are backwards (True denotes failure, False indicates
success), but they're all consistent with each other so I left those alone.

63103b6705 luck confusion
Remove a couple of false comments about Luck, and an unreachable
switch case based upon them.  I don't know if the comment in you.h was ever
true, but it was false by the time Kevin brought across assorted changes
from slash'em however many years ago.  Full moon does not change the range
of possible Luck values, and ``rn2((Luck + 6) >> 1)'' produces a value
between 0 and 8 for prayer result, never 9.  Natural luck is always within
the range of -10 to +10, and extra luck from carrying blessed or cursed
luckstone can add or subtract another 3.  Full moon and Friday the 13th
change the equilibrium point for luck timeout but do not change the overall
range of possible values, which remains at -13 to +13.

6bcfa8f88b [baby] long worms
Between the addition of worm body parts and the phrasing of engulfing/
digesting status, I remembered an oddity with the vanquished monster list:
it shows baby long worms right next to adult long worms; both were defined
as level 8 monsters.  It also turns out that babies dealt more damage per
attack than adults; that was counterintuitive, to put it mildly.  Boost
long worms from level 8 to 9; drop baby long worms from level 8 to 5, half
rounded up just like the relationship between baby and adult purple worms
(who are levels 8 and 15, respectively).  And increase the damage for adult
long worm attack (was 1d4, now 2d4); drop it for baby (was 1d6, now 1d4).

b6b522398d fix part of #H43 - probing feedback when engulfed
From a bug report, feedback of the form

Status of the fog cloud (neutral):  Level 2  HP 5(5)  AC 0, engulfed you.

sounds odd.  "Engulfing you" seems a little odd as well, since the engulf
has already taken place, but I think it works out better.  For symmetry,
replace "swallowed you" by "swallowing you".  But that one will never
occur, because all the animals with engulfing attacks will now yield the
more precise and much more significant "digesting you".

     The code formatting is strange.  Lining up the text parts works out
a lot better than attempting to fit the associated tests within the space
left after the large indentation being used.

Hi. I'm a sourcediver but not a source compiler.
I use the Mac carbon port under Mac OS X. But enough
about me; I noticed these things:

	Polyself/Anatomy Bugs:

- Mimics are amorphous, so they should have jelly
parts rather than animal parts.
- Piercers, trappers and lurkers above have animal
parts, including "head," but they are M1_NOHEAD.
- All elementals have vortex body parts. This should
only be the case for air elementals.
(Remember: stalkers, unlike the other elementals, have
heads.)
- Krakens ought to have tentacles, like jellyfish. ("A
gush of water hits the kraken's left fin!")
- Worms have snake body parts, but they shouldn't have
scales.
[...]

 This patch:
- adds worm_parts
- gives krakens tentacles
- ensures that stalkers have a head

ff553c6995 latent level arrival message bug (trunk only)
Something I noticed during a level change in slash'em:
        You hear the sounds of civilization.  You fly down the stairs.
The first message ought to follow the second.  Our only arrival messages
that are handled via the special level loader occur in the endgame where
travel is by magic portal, and the transit message given for portals is
for entering one rather than exiting at the far side, so this sequencing
problem can't currently be noticed in nethack.  But sooner or later there
will be levels reachable by stairs and having entry messages, or there'll
be some feedback added when magic portal transport finishes, and then we'd
get bitten by this.

     Tested by adding an arrival message to each of the bigroom variants.

73e9225d88 scroll usage; also spell of ID (trunk only)
Make a not-very-robust fix for the report from <email deleted> about
being told a scoll disappears as you read it, then for the case of cursed
remove curse being told that the scroll disintegrates.  He missed similar
case for scroll of fire erupting into flames after it had disappeared.
This suppresses the "disappears" part of the scroll reading message for
those two cases, but won't be very reliable if other scroll messages
referring to the scroll itself get introduced in the future.  [Several
paths through scroll of fire won't report that it burns, and now it doesn't
give the disappears message any more.  I don't think that's worth worrying
about; the scroll leaving inventory after burning up is implicit.]

     Also cut down on redundant feedback for several scrolls (genocide,
charging, identify, stinking cloud) that start off by informing the player
what they are.  That's only needed when the the player doesn't already
know the type of scroll.  I've always felt it silly to be told that I've
"found a scroll of genocide" when I'm intentionally reading a known scroll
of genocide.  All these types of scroll give a subsequent prompt which
makes them recongizable if you somehow manage to choose the wrong object
when picking the one to read.

    Lastly, make spell of identify behave like ordinary uncursed scroll of
identify by default instead of ususally ID'ing multiple items.  Now you'll
need to be skilled or better in divination spells skill in order to get the
blessed scroll effect out of it.  And give some feedback if the spell is
cast when not carrying any inventory; it was just silently moving on to the
user's next command in that case.

6a892dbf0c ghoul fodder (trunk only)
I doubt if many players in nethack ever have pet ghouls (in slash'em
they're the necromancer's starting pet), but if so, provide them with a
portable food source by letting ghouls eat dead eggs in addition to tainted
corpses.  Also, let them eat fresher varieties of either when they're about
to starve to death.  Treat lizard & lichen corpses as always fresh since
they never become tainted (probably ruining slash'em necromancers' present
pet food of choice, though they'll still be able to eat lizard corspes if
starving).

     I set the omnivore flag in their monster definition.  Previously they
had been left as non-eaters despite the fact that they need to eat.  When
the flag wasn't set, a hero who poly'd into one and then put on an amulet of
unchanging could go a very long time (thousands of turns) before the hunger
imposed by wearing an amulet finally made him/her become hungry.  (Same as
with any other truely non-eating monster, so not really a big deal.)

     Also, avoid the expression &mons[obj->corpsenm] for objects where the
corpsenm field isn't applicable, in case the default value ever changes from
0 (PM_GIANT_ANT) to NON_PM (-1).

     Add a couple of new "spell is almost gone" messages that occur when

re-read a spellbook to reinforce memory of a known spell.

     When "too hungry", you can't cast any spells, except detect food so
that you can find something to eat.  When "too weak" you couldn't cast any
spells at all; now you can cast restore ability so that you can recover
lost strength.  [We still need to come up with a better crowning bonus for
monks than spellbook of restore ability.]  I couldn't think of a reasonable
exception for the "can't cast when carrying too much" restriction.  If we
can come up with one (levitation?), then remove curse could/should become
an exception for the "no free hands" restriction.

57c3fa60b7 C343-3 creation of the Ranger quest start level
Normal maze levels are initialized from x == 3 thru COLNO-1.  However,
levels that use the INIT_MAP spec go thru mkmap, which initializes the level
starting at x == 1.  This usually makes no difference, but does in the case
of levels that also use GEOMETRY:left.  This was the case with the Ranger
start level and caused the leftmost 2 locations to be room locations but
unreachable.  The Juiblex level actually had the same behavior, but this
was harmless because the MAP in that case was smaller.

Fix is to set the xstart=1 for levels with INIT_MAP and GEOMETRY:left.
The rest of sp_lev works just with this (when INIT_MAP was used, that is).

3096fc47dc spell retention feedback (trunk only)
Instead of just marking forgotten spells with an asterisk, add a new
column to the '+' spell menu which gives an estimate of how well the spell
is remembered.  Precision of the estimate depends upon the hero's skill in
the category of spell; expert gets the most detail with a low-to-high range
spanning just 2%, such as 19%-20% or 75%-76%; skilled sees 5% ranges; basic
10%, and unskilled the least detail with 25% ranges (ie, one of 1-25, 26-50,
51-75, or 76-100 for percentage of time left available for the spell).
[The tab-separator variant for the menu is untested.]

     This fixes an off by one bug for spell retention.  It got set to 20000
as intended when a spellbook was read, but then it would be decremented to
19999 before the player had a chance to do anything else, cheating him out
of 1 turn of memory.  Spells known at game start last exactly 20000 turns.

     Also, adjust the point at which you're allowed to reread a spellbook
and refresh your memory of the spell.  When the current spell system was
instituted, that was 10% of the retention period (1000 turns or less left
out of 10000); when retention got doubled to 20000 turns, the relearn point
was left as is.  Increasing it to 10% (ie, doubling to 2000) makes it fit
better with the displayed retention percentages.  Otherwise expert casters
would be left to guess when they've hit that point (1000 is 5%, falling
within their 5%-6% range, which really indicates (4%+1) to 6%).  At 10%,
it's the threshold for the 9-10 range for experts, 5-10 range for skilled,
and 1-10 range for basic so the player can see when it has been reached;
only unskilled, with a bottom range of 1-25, is left to guess.  Players
will likely prefer to wait until later, when the spell is nearly expired,
to refresh, but if they're about to abandon their books on the way to the
endgame then being able to re-read sooner is beneficial.

5d732c47a3 partial fix for #H38 - hallucination of personal names (trunk only)
This fixes the monnam() family of functions so that hallucinated
personal names, such as Barney, won't be prefixed by "the".  It uses the
same hack as is used for shopkeeper names:  single character prefix on
names which warrant some handling other than the default.  rndmonnam()
strips that off, so unmodified callers (which is almost all of them...)
retain the same behavior has before.

     There are several capitalized names that I have no idea whether need
to be treated as personal names:
  Evil Iggy - name, or type of monster named after someone?
  Totoro    - no clue
  Invid     - ditto
  Vorlon    - just guessing that it's a species rather than an individual.
I couldn't remember whether Godzilla was baby Godzilla's mother or father,
so I went with female there.  So far, no callers of rndmonnam() care about
gender so it doesn't make any difference.  Because of that, I didn't look
though the non-capitalized names to see whether any should be all male or
all female and need one of the other prefix codes.

     I've added "were-rabbit" from the Wallace & Gromit movie.  The recent
ads for its DVD release reminded me that I was going to add that back when
the movie first came out.  I haven't seen it but the creature name fits.

     I also fixed Smokey Bear.  Smokey the Bear is a common misspelling;
I thought we had fixed that ages ago, back when people still had some clue
as to who in the world he was.

     This implements the improvement for spellcasters.  After they make

72d68851e2 M164: finding saved games in QT nethack start
Only 5 months old.  The Unix code to find saved games, currently only enabled
for Qt use, fails to use fqname and SAVEPREFIX, so it doesn't find saved
games when prefixes are in effect.

a1b0e08421 Xorns in stone outside Sokobon and other special levels
First reported 12/13/2003, I think, but my archives contain more recent reports
too.  Special level specs like NON_PASSWALL and NON_DIGGABLE only apply
to the map sections for which they are specified.  So, on special levels of
Sokobon, the large surrounding area is stone, but have no special flags set.
So, it was possible to teleport a Xorn and have it appear in this outer area.

Addressed this by checking the perimeter of the map(s) and if all are
nondiggable and nonpassable, propagate this to the surrounding stone.
This appears to be the intent on such levels, so there is no need to
force the affected special levels to explicitly specify this.

f11d009b4c gender and size of leaders and nemeses
Combo fix based on several reports and additional research.
In quest.txt and/or data.base, the Grand Master, Arch Priest, Ixoth, Master
Kaen, Nalzok, Scorpius, and the Master Assassin are all referred to as male
via reference: his or him.  Ideally, there would be a way to parameterize
this in the quest.txt, but I don't see a clear way to do that at this time.
For the time being at least, set the M2_MALE flag for these monsters.

The Dark One was referred to via "his" once in the quest.txt.  This case
I was able to modify the offending text rather than forcing a gender.

Orion and Norn are referred to as a giant in data.base but their size did
not correspond.  I left the symbol as S_HUMAN although perhaps it should
be S_GIANT.  Finally, Orion, the Norn, Cyclops and Lord Surtur, as
giant-types, should be able to tear webs.

98685ea234 `spestudied' manipulation for polymorphed spellbooks (trunk only)
From a bug report... some
special case handling for polymorph of spellbooks never worked as intended.
It's possible to polymorph a spellbook, use it to learn a new spell, and
then repeat as many times as you like unless/until you run out of polymorph
magic or the small chance of "object shuddering" causes it to be destroyed.
Polymorph was incrementing the book's ``number of times read'' field with
the intent that it would fade to blank after being read 3 times (which
turns out to the 4 times since the check is actually for re-reading 3 times
after the first).  That didn't work because the spestudied field was ignored
when learning a new spell, only checked when relearning a known spell.

     Now it will be checked when learning a new spell, and also the book
tweaking during polymorph is slightly more elaborate.  If you happen to
get a blank book during the item selection, it will have a read counter
of 0 and can be re-polymorphed into something readable.  But if you get
some other book, its read counter will be set to one greater than than the
original book's (same as before).  And then the counter will be checked
to see if it has gone over the limit, in which case the book will be made
blank and its counter will be reset to a random value.  Re-polymorphing
that blank book again has 1/4 chance apiece among the following cases
  book gets blanked again; goto step 1...
  book is non-blank but too faint to read; reading attempt will fail
  book can be read normally and then re-read once
  book can be read normally and then re-read twice
which is more inline with the intent of the original special case code.
It's actually slightly nastier since you'll occasionally get a book for a
spell you don't know yet but then not be able to learn it from that book.

fbe6b0278f fix #Q251 - reading engravings while asleep
From a bug report, floating down onto an engraving
due to levitation timeout would yield "You read: <engraving text>" even if
you were asleep at the time.  Random teleport while asleep could produce a
similar result.  The problem was actually a little bigger:  you'd also get
"You see <object> here" if there was an object instead of or in addition to
an engraving.

702060c4de monsters with multiple attacks missing wildly (trunk only)
Reduce verbosity for monsters with multiple attacks who "swing wildly
at you and miss" or "miss your displaced image" due to their confusion or
your invisibility or displacement.  It's aggravating to sit through that
three times for claw/claw/bite or swing/swing/kick when those longer
descriptions of why such missing happened guarantee multiple --More--
prompts.  (Can't simply use Norep() to deal with this because wildmiss()
varies its messages.)

     This makes monsters marginally smarter--independent of their defined
intelligence levels--by skipping their remaining attacks when the first
turns out to be targetted at nothing.  The exception is for monsters with
both melee and spell attacks; they'll keep going in case they end up
choosing a spell which doesn't need a target location.  (It's rather ironic
that the most intelligent monsters are the ones who'll foolishly continue
swinging at thin air.  This could be improved by forcing then to skip ahead
to their spell attack.)  Exploding monsters aren't affected because they
don't have multiple attacks.  Offhand I can't think of any other situation
where a wild miss on the first of N attacks could still yield a successful
result on any of the other N-1 actions.

     Monsters attempting ranged attacks who get multiple shots (due to
multiple weapon attacks per turn rather than to multi-shot volley during
a single attack) will end up conserving ammo when they stop after seeing
that the first shot didn't find a target.  Note that trying to attack you
but accidentally attacking some other target isn't affected since that
doesn't yield the wild miss outcome.  Intelligent monsters probably ought
to recognize that their attack against you ended up hitting someone else
and refrain from repeating that mistake N-1 more times.  Whether feedback
from that ought to carry over to their next turn is not so clear cut.

49084e6deb zapping unseen wands (trunk only)
Noticed recently when a user reported that an unseen monster zapping
an unseen wand caused wand of striking to become discovered.  [That was
because the zap also hit a door and the code for the latter didn't check
whether the wand had been seen, and it got fixed a couple of weeks ago.]
When the player zaps wands while the hero is blinded, it was discovering
(for the cases where the effect can be observed without sight) the wand
even though the wand's description was unknown (showed in inventory as
"a wand").  This replaces the calls to makeknown() in zap.c with calls to
new learnwand(), which checks whether the wand description is known; you
no longer discover something you've never seen.  Reverse effect has also
been added:  if the type of wand has been discovered earlier, zapping an
unseen wand (another of the same type, picked up when blind and zapped
while still blind) will now mark it as seen (to show up in inventory as
"a wand of <whatever>" instead of just a "a wand").  The latter aspect
really ought to be independent of prior discovery, but we currently have
no way to record "we know what this particular item does even though we
don't know what type of item it is yet".  [If we add that, it would be
applicable to potions (when operating on stacks) and rings too.]

     Minor change:  zapping yourself with wand of opening or spell of
knock will remove attached ball&chain rather than give a "chain quivers"
message.  Explicitly zapping the chain already did that; if the unlocking
magic works on the chain connected to your leg then it really should also
work on your leg connected to the chain.  Zapping unlocking at yourself
probably should also scan inventory to check for carrying locked chests,
but I didn't add that.  (If added, then locking magic will need to be
augmented likewise.)

     This also fixes <Someone>'s recent complaint:  zapping an unknown
wand of teleportation at yourself didn't make it become discovered.
Now it will be, under the same circumstances as when you're riding:  if
teleport control causes you to be prompted for destination, or if random
destination moves you more than jumping distance away from your original
position.  (The Stunned exception to teleport control, which was missing
in zap_steed, perhaps ought to be moved into the macro definition of
Teleport_control itself so that all code always handles it consistently.)

e2dd0a12ae fix #H30 - rn2(0) from off by 1 bug in special level door creation
From a bug report, the placement
of random doors by the code that loads special levels would attempt to
evaluate rn2(0) and either get a divide by zero crash (normal build) or an
impossible warning (DEBUG enabled when compiing rnd.c, done automatically
when BETA is defined).  The problem was only noticable for random door in
a 1x1 room; none of our distributed levels specify such a thing so regular
users won't have encountered this bug.  It's a one line fix.

     Altar placement in temples also had a quirk of a similar nature.  It
wouldn't trigger rn2(0) problems but would always place the altar to left
of mid-point in rooms with even width and above the center point in ones
with even height.  Now the placement is randomized so that sometimes it'll
be to the right and/or below mid-point in such cases.

     This also simplifies a couple other instances of similar expressions
that I spotted.
