Also includes support by paxed for polearm targeting using the
frame color.
Also renames USE_TILES to TILES_IN_GLYPHMAP which is a more
accurate description.
Not all window interfaces have full support for the color framing
of the background square yet.
MS-DOS needs further work (to bring it to both VESA and VGA, with
and without tiles.
Windows GUI is missing support.
X11 and Qt have been started, but may require further refinement.
The consolidation of global variables from scattered source
files into decl.c and declared in decl.h was begun in 3.7.0.
Their placement in common files was done for centralized
initialization and potential re-initialization during a
"play again" scenario.
It wasn't really necessary for all of them to be housed in a
single huge structure to meet the "play again" requirement,
and the single huge structure has been a little unwieldy when
it comes to maintenance.
Following this commit, instead of one single extremely large structure
named 'g' to house all of the relocated global variables, they
are distributed into several ga through gz.
To make things easy for the developer, each variable is placed
into the struct corresponding to the starting letter of the variable.
That way, no lookup is required in order to know which struct houses
a particular variable, it is a simple match to the starting letter
for all the centralized global variables.
A global variable named 'amulets', would be found in ga.
ga.amulets
^ ^
A global varable named 'move', would be found in gm.
gm.moves
^ ^
A global variable named 'val_for_n_or_more' would be found in gv.
gv.val_for_n_or_more
^ ^
A global variable named 'youmonst' would be found in gy.
gy.youmonst

When dist2() got changed to use coordxy parameters, a macro that uses
it in its definition was overlooked and it had (int) casts in it.
That caused a warning about possible data loss when the int
then got converted to coordxy for the dist2() call.
Give online2() coordxy parameters instead of int, like its bretheren.
Avoid a couple of implicit conversion warnings where ints were being assigned
to smaller uchar or ints being assigned to smaller short.
A couple of signed vs unsigned warnings on some rumor processing.
Avoid some signed vs unsigned warnings in mdlib/makedefs where a signed int
param eventually got used in an external call that took size_t.
Eliminate all of it by just having the outer NetHack routine also take
a size_t.
Lastly, insert some default C99 alternative time-related code
in mdlib/makedefs since asctime() and ctime() are being flagged as
deprecated in the upcoming C23 standard and will now start to trigger
warnings for anyone using a C23-compliant compiler.
Instead of using index() macro defined to strchr, use C99 strchr.
Instead of using rindex() macro defined to strrchr, use C99 strrchr.
If you want to try building on a platform that doesn't offer those
two functions, these are available:
define NOT_C99 /* to make some non-C99 code available */
define NEED_INDEX /* to define a macro for index() */
define NEED_RINDX /* to define a macro for rindex() */

If the VESA mode chooses a mode with 8 bit pixels, but the tile set
has too many colors for that, a null dereference can result when
trying to set up the nonexistent palette. Catch this condition and
refuse to set VESA mode instead.
To test 16-color mode, specify OPTIONS=video:vga explicitly;
autodetect will choose a VESA mode if it can.
* Draw tiles correctly when redrawing from panning or from changing
the map mode among text, tiles and overview. Previously, this would
draw everything with the tile at the hero's position.
* Draw corridor walls with the stone tile.
* Map the statue colors to the nearest neutral tone among the main
16 colors. This mainly affects altars and female cats.
* Fix the code that shows statues as the generic statue tile. This
code could be deleted, but the statues don't draw with the full
range of gray tones.
* Document the option OPTIONS=video:vesa.

move out-of-date hints files to the outdated folder.
rename the hints files, and hints/include files that are currently
named *.2020 to *.370 (next release number).
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.
This evolves and hopefully eases the game-build requirements by
removing game-compile dependencies on any header files generated
by the makedefs utility, including:
date.h dependency and its inclusion is removed and comparable functionality
is produced at runtime via new file src/date.c.
pm.h dependency and its inclusion is removed and comparable functionality is
produced by moving the monster definitions from monst.c into new header
file called monsters.h and altering them slightly. The former pm.h header
file #define PM_ values are now replaced with appropriate emitted enum
entries during the compiler preprocessing.
onames.h dependency and its inclusion is removed and comparable functionality
is produced by moving the object definitions from objects.c into new header
file called objects.h and altering them slightly. The former onames.h header
file #define values are now replaced with appropriate emitted enum entries
during the compiler preprocessing.
artilist.h has been slightly altered, and the former onames.h artifact-related
header file #define ART_ values are now replaced with appropriate emitted enum
entries during the compiler preprocessing.
makedefs can still produce date.h (makedefs -v), pm.h (makedefs -p), and
onames.h (makedefs -o) for reference purposes. They won't be used during
the compiler.
The other uses for makedefs remain. They are used to prepare external
file content that the game utilizes, not prerequisite code for the
compile:
makedefs -d (database)
makedefs -r (rumors)
makedefs -h (oracles)
makedefs -s (epitaphs, engravings, bogusmons)
date.c
Pull the code for date/time stamping from mdlib.c into date.c.
Set date.o to be dependent on source files, header files, and .o files
so that date.o is rebuilt from date.c when any of those changes, thus
ensuring an accurate date/time stamp. It also includes git sha
functionality formerly done by makedefs writing #define directives
into include/date.h. For unix it passes the git info on
the compile line for date.c (via sys/unix/hints/linux.2020, macOS.2020)
nethack --dumpenums (optional, but on by default)
Allow developer to obtain some internal enum values from NetHack
without having to resort to an external utility such as
makedefs.
Uncomment #define NODUMPENUMS in config.h to disable this.
The updates to sys/windows/Makefile.gcc have not been tested yet.
There were multiple symbol-related lists that had to be kept
in sync in various places.
Consolidate some of that into a single new file
defsym.h
with a set of morphing macros that can be custom-called from
the various places that use the sym info without maintaining
multiple occurrences. Most maintenance can be done there.
Rename monsym.h to sym.h since it looks after some
symbols not related to monsters now too.
The defsym.h header file is included in multiple places to
produce different code depending on its use and the controlling
macro definitions in place prior to including it.
Its purpose is to have a definitive source for
pchar, objclass and mon symbol maintenance.
The controlling macros used to morph the resulting code are
used in these places:
- in include/sym.h for enums of some S_ symbol values
(define PCHAR_ENUM, MONSYMS_ENUM prior to #include defsym.h)
- in include/objclass.h for enums of some S_ symbol values
(define OBJCLASS_ENUM prior to #include defsym.h)
- in src/symbols.c for parsing S_ entries in config files
(define PCHAR_PARSE, MONSYMS_PARSE, OBJCLASS_PARSE prior
to #include defsym.h)
- in src/drawing.c for initializing some data structures/arrays
(define PCHAR_DRAWING, MONSYMS_DRAWING, OBJCLASS_DRAWING prior
to #include defsym.h)
- in win/share/tilemap.c for processing a tile file
(define PCHAR_TILES prior to #include defsym.h).
