30b557f7d5 change xchar to other typedefs
One of the drivers of this change was that screen coordinates require a
type that can hold values greater than 127. Parameters to the window
port routines require a large type in order to be able to have values
a fair bit larger than COLNO and ROWNO passed to them, particularly for
their use to the right of the map window.

This splits the uses of xchar into 3 different situations, and adjusts
their type and size:

                        xchar
                          |
               -----------------------
               |          |          |
            coordxy     xint16     xint8

coordxy: Actual x or y coordinates for various things (moved to 16-bits).

xint16:  Same data size as coordxy, but for non-coordinate use (16-bits).

xint8:   There are only a few use cases initially, where it was very
         plain to see that the variable could remain as 8-bits, rather
         than be bumped to 16-bits.  There are probably more such cases
         that could be changed after additional review.

Note: This first changed all xchar variables to coordxy. Some were
reviewed and got changed to xint16 or xint8 when it became apparent that
their usage was not for coordinates.

The Copyright notice is placed by tty internal routines writing onto
the BASE_WINDOW fairly early in the startup sequence.

The prompt to "Destroy old game? [yn] (n)" is using the in-game
routine to write to the message window at the top of the screen and
prompt there, just like in-game prompts and messages.

If the player answered 'y' to that, the prompt for
"Shall I pick character's race, role, gender and alignment..."
appeared immediately after. That one, however, is written using
the BASE_WINDOW routines in tty, like the copyright notice.

This change does the following:

It moves the copyright lines down a little bit leaving room for the
"Destroy.." prompts.

It places the "Shall I pick characters's..." prompt further down the
screen by default, leaving some room for about 3 raw_print startup
messages after the copyright notice, just in case there are any.
The "Shall I pick character's..." prompt will still appear immediately
if there is a prompt such as "Destroy old game?..."

There were a couple of other issues around raw_print startup messages
too. Those are delivered using a raw_print mechanism to ensure they
are written even if the window-port is not fully operational. However,
they were only on the screen for the blink of an eye. This call
sequence in restore.c made them disappear almost immediately:
     docrt() -> cls()

Put in a mechanism to detect the presence of raw_print messages
from the early startup, and if there were some, wait for a
keypress before obliterating the unread notifications.

5d56da3d32 bubble/cloud save/restore overhaul
The air bubbles on the Plane of Water and the clouds on the Plane of
Air were being saved and restored as part of the current level's state
(which is the 'u' struct and invent and such) rather than with the
current level itself.  That was ok for normal play, but for wizard
mode's ^V allowing you to return to a previously visited endgame level
after moving to a different one it meant a new set of bubbles for
Water and new set of clouds for Air.  Even that was ok since it only
applied to wizard mode, but using #wizmakemap to recreate Water or Air
while you were on it added a new set of bubbles or clouds to the
existing ones.  If repeated, eventually there wouldn't be much water
or air left.

Instead of just adding a hack to #wizmakemap, change save/restore to
keep the bubbles/clouds with the level rather than with the state.
That wasn't trivial and now I know why the old odd arrangement was
chosen.  Saving hides u.uz by zeroing it out for levels that the hero
isn't on and it is zero during restore so simple checks for whether a
given level is water or air won't work.

This also adds another non-file/non-debugpline() use of DEBUGFILES:
 DEBUGFILES=seethru nethack -D
will make water and clouds be transparent instead of opaque.  It also
makes fumaroles and other light-blocking gas clouds be transparent
which wasn't really intended, but avoiding it would be extra work that
doesn't accomplish much.

dadbea1d8c preliminary fix for github issue #726 - restdamage
Reported by entrez, restoring a saved game runs the shop wall/floor
damage repair routine.  It was taking place before attached ball
and chain were fully restored so the repair routine treated them as
ordinary objects if they happened to be in a wall gap that gets
fixed on the same turn as restore takes place.  They could end up
being moved to a spot that's too far from the hero and then trigger
an impossible "b&c distance".

This restores ball and chain before shop damage repair takes place
so the repair routine deals with them sanely and the impossible won't
occur any more.  However, the repair still happens before the current
level's map has been displayed and that looks pretty strange during
the shopkeeper's message.  Also, if the hero and the ball start on
opposite sides of the gap, after the gap is repaired the ball will
still be shown as a remembered object at its old spot even though it
ends up being located at the hero's feet.

Closes #726

but more work is needed...

1e90f89203 Chronicle of major events, and livelog
Log game events, such as entering a new dungeon level, breaking
a conduct, or killing a unique monster, in a new "Major events"
chronicle. The entries record the turn when the event happened.
The log can be viewed with #chronicle -command, and the entries
also show up in the end-of-game dump, if that is available.

This feature is on by default, but can be disabled by
defining NO_CHRONICLE compile-time option.

This also contains "live logging", writing the events as they
happen into a single livelog-file. This is mostly useful for
public servers. The livelog is off by default, and must be
compiled in with LIVELOG, and then turned on in sysconf.

Mostly this a version of livelogging from the Hardfought server,
with some changes.

b1d76a772f fix github issue #596 - wishing exploit
for helm of opposite alignment.

Discovered and described by vultur-cadens.

The #adjust command can be used to split an object stack and if the
shop price of the two halves are different, the new stack will have
its obj->o_id modified to make the prices the same.  That could be
used to tip off the player as to what the low bits of the next o_id
will be.  Since no time passes, no intervening activity such as
random creation of a new monster can take place, so the player could
wish for something that depends on o_id with some degree of control.
Matters mainly for helms of opposite alignment intended to be used
by neutral characters since the player isn't supposed to be able to
control that.  (Other items like T-shirt slogan text and candy bar
wrapper text had a similar issue but controlling those wouldn't have
had any tangible difference on play.)

The issue writeup suggested allowing the player to specify a helm's
alignment during a wish.  That would defeat the purpose of having
o_id affect the helm's behavior in an arbitrary but repeatable way
so is rejected.

I implemented this fix before seeing a followup comment that suggests
using a more sophisticated decision than 'obj->o_id % N' for the
arbitrary effect.  This just increments context.ident for the next
obj->o_id or mon->m_id by 1 or 2 instead of always by 1 and should
be adequate.  It also has the side-effect that two consecutive wishes
for helm of opposite alignment won't necessary give one for each of
the two possible 'polarities', even with no intervening activity by
monsters, reinforcing the lack of player control.

Minor bonus fix:  it moves the incrementing check for wrap-to-0 into
a single place instead of replicating that half a dozen times.  Ones
that should have been there for shop billing and for objects loaded
from bones files were missing.

1f6c1d0f42 expand the glyphs
The walls for the mines, gehennom, knox, and sokoban had been
changed at the "tile"-level, with no awareness of the core game,
or non-tile interfaces.
- Expand the glyphs to include a set of walls for the main level
as well as each of those mentioned above.

Altars had been adjusted at the map_glyphinfo() level to substitute
some color variations on-the-fly for unaligned, chaotic, neutral,
lawful altars, and shrines. The tile interface had no awareness of
the feature.
- Expand the glyphs to include each of the altar variations that
had been implemented in the display code for tty-only. This required
the addition of four placeholder tiles in other.txt. Someone with
artistic skill will hopefully alter the additional tiles to better
reflect their intended purpose.

Explosions had unique tiles in the tile window port, and the display
code for tty tinkered with the colors, but the game had very little
awareness of the different types of explosions.
- Expand the glyphs to include each of the explosion types: dark,
noxious, muddy, wet, magical, fiery and frosty.

Pile-markers to represent a pile had been introduced at the
display-level, without little to no awareness by the core game.
- Expand the glyphs to include piletops, including objects,
bodys, and statues.

Recently male and female variations of tiles and monsters had been
had been introduced, but the mechanics had been mostly done at the
display-level through a marker flag. The window port interface then
had to increment the tile mapped to the glyph to get the female version
of the tile.
- Expand the glyphs to include the male and female versions of the
monsters, and their corresponding pet versions, ridden, detected
versions and statues of them.

Direct references to GLYPH_BODY_OFF and GLYPH_STATUE_OFF
in object_from_map() in pager.c were getting incomplete results.
- Add macros glyph_to_body_corpsenm(glyph) and
glyph_to_statue_corpsenm(glyph) macros for obtaining the corpsenm
value after passing the glyph_is_body() or glyph_is_statue() test.

Other relevant notes:

- The tile ordering in the win/share/*.txt tile files has been altered,
other.txt in particular.

- tilemap.c has had a lot of alterations to accommodate the expanded
glyphs. Output that is useful for troubleshooting will end up in
tilemappings.lst if OBTAIN_TILEMAP is defined during build.
It lists all of the glyphs and which tile it gets mapped to, and also
lists each tile and some of the references to it by various glyphs.

- An array glyphmap[MAXGLYPH] is now used. It has an entry for each
glyph, ordered by glyph, and once reset_glyphs(glyph) has been run, it
contains the mapped symindex, default color, glyphflags, and tile
index.
If USE_TILES is defined during build, the tile.c produced from the
tilemap utility populates the tileidx field of each array element with
a glyph-to-tile mapping for the glyph. Later on, when reset_glyphmap()
is run, the other fields of each element will get populated.

- The glyph-to-tile mapping is an added field available to a window
port via the glyphinfo struct passed in the documented interface. The
old glyph2tile[] array is gone. The various active window ports that
had been using glyph2tile[] have been updated to use the new interface
mechanism. Disclaimer: There may be some bug fixing or tidying
required in the window port code.

- reset_glyphmap() is called after config file options parsing
has finished, because some config file settings can impact the results
produced by reset_glyphmap().

- Everything that passes the glyph_is_cmap(glyph) test must
return a valid cmap value from glyph_to_cmap(glyph).

- An 'extern glyph_info glyphmap[MAX_GLYPH];' is inserted into the
top of only the files which need awareness of it, not inserted into
display.h. Presently, the only files that actually need to directly
reference the glyphmap[] array are display.c, o_init.c (for shuffling
the tiles), and the generated tile.c (if USE_TILES is defined).

- Added an MG_MALE glyphflag to complement the MG_FEMALE glyphflag.

- Provide an array for wall colorizations. reset_glyphmap() will draw
the colors from this array: int array wallcolors[sokoban_walls + 1];
The indices of the wallcolors array are main_walls (0), mines_walls
(1), gehennom_walls (2), knox_walls (3), and sokoban_walls (4).
In future, a config file option for adjusting the wall colors and/or
an 'O' option menu to do the same could be added. Right now, the
initializaton of the wallcolors[] array entries in display.c leaves the
walls at CLR_GRAY, matching the defsym color.

- Most of the display-level kludges for some of the on-the-fly
interface features have been removed from map_glyphinfo() as they
aren't needed any longer. These glyph expansions adhere more closely to
the original glyph mechanics of the game.

- Because the glyphs are re-ordered and expanded, an update to
editlevel will be required upon merge of these changes.

f855fb5e45 Remove g.monstermoves
It's redundant with g.moves, so there is no more need for it.

Way, way back, it looks like g.moves and g.monstermoves can and did
desync, where g.moves would track the amount of moves the player had
gotten (and would therefore increase faster if the player were hasted)
and g.monstermoves would track the amount of monster move cycles, aka
turns. But this has not been the case for a long time, and they both
increment together in the same location in allmain.c. There are no
longer any cases where they will not be the same value.

This is a save-breaking change because it changes struct
instance_globals, but I have not updated the editlevel in this commit.

0e05c94400 Remove requirement of object probs adding to 1000
When discussing the recent commit that removed makedefs -o from the
build process, nhmall pointed out that a sanity check ensuring all
objects within one class add up to 1000 probability had been removed as
well. This requirement was a perennial thorn in the side for anyone
doing anything that touches object probabilities, because allocating
probability to something meant deciding what to take it away from,
without a good way to evenly distribute that across all the other
members of the object class.

I had gotten around this in xNetHack by removing the sanity check and
making mkobj() total up the probability within an object class and then
using that instead of 1000. This commit takes a similar approach, but
instead of inefficiently recalculating the sum every time mkobj() is
called, it instead computes it at the start of the game or when
restoring the save file and stores it in a global variable.

This fixes a slight bias problem with rings - they are all supposed to
be of equal probability, but there are 28 of them and 1000 is not evenly
divisible by that, so the old formula made the later rings slightly more
likely. Now instead of a 35/1000 or 36/1000 chance, they are all
uniformly 1/28. (Internally they have a oc_prob of 1 now, not 0).

Gems are also weird, because their oc_prob values change every level.
This ought to have still worked without a change, because the arcane
formula for assigning the probabilities would still end up with them
adding to 1000. But I added in code to reset the total gem probability
anyway; this may help make the formula less arcane in the future.

There is still a sanity check against object classes having a nonzero
number of objects but zero total probability, in which case an
impossible will be thrown and every member of the class will be given
equal probability. I also downgraded the "probtype error" panic in
mkobj() to an impossible because it has a reasonable failure case -
return the first item in that class.

Change the damage fix messaging to be more specific when

"A trap was removed from the floor", which sounds really silly

Change the damage fixing so the shopkeeper will fix one damage spot

further adjustments to the window port interface to pass a pointer
to a glyph_info struct which describes not just the glyph number
itself, but also the ttychar, the color, the glyphflags, and the

This affects two existing window port calls that get passed glyphs

0c3b9642e4 pmnames mons gender naming plus a window port interface change
add MALE, FEMALE, and gender-neutral names for individual monster species
to the mons array. The gender-neutral name (NEUTRAL) is mandatory, the
MALE and FEMALE versions are not.

replace code uses of the mname field of permonst with one of the three
potentially-available gender-specific names.

consolidate some separate mons entries that differed only by species into a
single mons entry (caveman, cavewoman and priest,priestess etc.)

consolidate several "* lord" and "* queen/* king" monst entries into
their single species, and allow both genders on some where it makes some
sense (there is probably more work and cleanup to come out of this at some
point, and the chosen gender-neutral name variations are not cast in stone
if someone has better suggestions).

related function or macro additions:
    pmname(pm, gender) to get the gender variation of the permonst name. It
    guards against monsters that haven't got anything except NEUTRAL naming
    and falls back to the NEUTRAL version if FEMALE and MALE versions are
    missing.

    Ugender to obtain the current hero gender.
    Mgender(mtmp) to obtain the gender of a monster

While the code can safely refer directly to pmnames[NEUTRAL] safely in the
code because it always exists, the other two (pmnames[MALE] and
pmnames[FEMALE] may not exist so use:
    pmname(ptr, gidx)
      where -ptr is a permonst *
            -gidx is an index into the pmnames array field of the
             permonst struct
pmname() checks for a valid index and checks for null-pointers for
pmnames[MALE] and pmnames[FEMALE], and will fall back to pmnames[NEUTRAL] if
the pointer requested if the requested variation is unavailable, or if the
gidx is out-of-range.

Allow code to specify makemon flags to request female or male (via MM_MALE
and MM_FEMALE flags respectively)to makedefs, since the species alone doesn't
distinguish male/female anymore. Specifying MM_MALE or MM_FEMALE won't
override the pm M2_MALE and M2_FEMALE flags on a mons[] entry.

male and female tiles have been added to win/share/monsters.txt.
The majority are duplicated placeholders except for those that were
separate mons entries before. Perhaps someone will contribute artwork in the
future to make the male and female variations visually distinguishable.

tilemapping via has the MALE tile indexes in the glyph2tile[]
array produced at build time. If a window port has information that the
FEMALE tile is required, it just has to increment the index returned
from the glyph2tile[] array by 1.

statues already preserved gender of the monster through STATUE_FEMALE
and STATUE_MALE, so ensure that pmnames takes that into consideration.

I expect some refinement will be required after broad play-testing puts it to
the test.

    consolidate caveman,cavewoman and priest,priestess monst.c entries etc

This commit will require a bump of editlevel in patchlevel.h because it alters
the index numbers of the monsters due to the consolidation of some. Those
index numbers are saved in some other structures, even though the mons[] array
itself is not part of the savefile.

Window Port Interface Change

Also add a parameter to print_glyph to convey additional information beyond
the glyph to the window ports. Every single window port was calling back to
mapglyph for the information anyway, so just included it in the interface and
produce the information right in the display core.

The mapglyph() function uses will be eliminated, although there are still some
in the code yet to be dealt with.

win32, tty, x11, Qt, msdos window ports have all had adjustments done to
utilize the new parameter instead of calling mapglyph, but some of those
window ports have not been thoroughly tested since the changes.

Interface change additional info:

    print_glyph(window, x, y, glyph, bkglyph, *glyphmod)
            -- Print the glyph at (x,y) on the given window.  Glyphs are
               integers at the interface, mapped to whatever the window-
               port wants (symbol, font, color, attributes, ...there's
               a 1-1 map between glyphs and distinct things on the map).
            -- bkglyph is a background glyph for potential use by some
               graphical or tiled environments to allow the depiction
               to fall against a background consistent with the grid
               around x,y. If bkglyph is NO_GLYPH, then the parameter
               should be ignored (do nothing with it).
                -- glyphmod provides extended information about the glyph
               that window ports can use to enhance the display in
               various ways.
                    unsigned int glyphmod[NUM_GLYPHMOD]
               where:
                    glyphmod[GM_TTYCHAR]  is the text characters associated
                                          with the original NetHack display.

                    glyphmod[GM_FLAGS]    are the special flags that denote
                                          additional information that window
                                          ports can use.

                    glyphmod[GM_COLOR] is the text character
                                       color associated with the original
                                       NetHack display.

Support for including the glyphmod info in the display glyph buffer
alongside the glyph itself was added and is the default operation.
That can be turned off by defining UNBUFFERED_GLYPHMOD at compile time.
With UNBUFFERED_GLYPHMOD operation, a call will be placed to map_glyphmod()
immediately prior to every print_glyph() call.

cf88808285 Fix stairs on oracle level bones
Recent change to the stairs structure now lets each stair keep
the destination level number and dungeon where the stairs go to.

When a level that can be on different depth (such as the Oracle)
became a bones level, and it was loaded in another game at different
depth, the stairs were still pointing to the old level number.

Save it as relative to the current level instead of absolute.

f8fcab3400 move 'g.restoring' to 'g.program_state.restoring'
Move the core's global restoring flag (not the same as main()'s
local resuming flag) to a more logical place.  Add a saving flag
in the process, but it isn't being set or cleared anywhere yet.
(Once in use it will probably fix the exception during save that
was just reported, but before that it would be useful to figure
out what specifically caused the event.)

The program_state struct really ought to be standalone rather
than part of struct g but I haven't made that change.

Removing an unused variable for wishing and some reformatting
that whent along with it got mixed in.  Removes some trailing
whitespace in sfstruct.c too.

Only lightly tested...

229930e505 Fixes and sanity checks for monster undetected and trapped states
Adds sanity checks for mtrapped and mundetected states.

Fixes cases where those were left in wrong state.

1. Trapped monster (eg. a nymph) teleported out of a trap
2. Monster was hiding under ball or chain, which then got removed
3. While restoring a level, a zombie corpse revived while monster
   was hiding under it
4. A general case where the only object was deleted off floor and
   a monster was hiding under it

Monsters hiding under ball or chain will now get revealed when
the b or c are moved.

e63fed627c obj->oextra->{omid,olong}
Change obj->oextra->omid from a usually-Null pointer field in
oextra to a simple 'unsigned' that doesn't need any allocation
beyond obj->oextra itself.  Value 0 means that it is not in use;
it is used to hold a monst.m_id and those are always non-zero.

Delete unused obj->oextra->olong.  'olong' used to be the last
field in struct obj, put there to force alignment of anything
which followed it back when obj structures were over-allocated to
append extra information.  It had a comment about being used for
temporary gold but whatever that was, temporary gold was gone long
before obj->oextra got introduced.

Bump EDITLEVEL since this invalidates existing 3.7 save files.

Remove a bunch of tabs from obj.h and save.c.

Whenever a lua script references a core struct obj, increment a counter

When lua script ends, the lua gc will free the free-floating objects.

groundwork only - window port interface change

This changes the last parameter for add_menu() from a boolean
to an unsigned int, to allow additional itemflags in future

There shouldn't be any functionality changes with this groundwork-only
change, and if there are it is unintentional and should be reported.

756f6a1006 fix a memory leak
Memory allocated for a trap in getlev() wasn't being freed.  There
is already one extra allocation which is supposed to get freed after
the loop, but the 'keepgoing' flag caused an extra trap allocation
before loop termination.  So the unintentional one got freed but did
so by intercepting the free for the end-of-list one.

Fruit had similar code which applied to full game save and restore
rather than level save and restore so wasn't as noticeable.
