446044e1d5 1st of a few sequencing changes
rename display_gamewindows() to init_sound_and_display_gamewindows()
(I know that's getting pretty long-named).

move activate_chosen_soundlib() into init_sound_and_display_gamewindows()
from moveloop_preamble().

Also included was a missing break in a switch related to sounds.

3d908c49ef take initial stab at macsound interface
Use macOS AppKit framework routines for a first cut at a
macsound soundlib interface.

Requires WANT_MACSOUND=1 on build.

Nothing has been done to move the stock sounds into the resources
of a bundle, so after building, if you want to try the stock sounds
out:
	cp sound/wav/*.wav ~/Library/Sounds

Because the NSSound macOS routines always do the search, supposedly
the following locations are searched in this order:
   1. the application’s main bundle
   2. ~/Library/Sounds
   3. /Library/Sounds
   4. /Network/Library/Sounds
   5. /System/Library/Sounds

Although not specifically implemented as of yet, it may be pretty
close to being able to put soundeffects wav files (by se_ name)
into ~/Library/Sounds working for the SND_SOUNDEFFECTS_AUTOMAP feature.

Feedback is welcome. Contributions for improving it are even more
welcome.

The new soundlib supporting file is named
sound/macsound/macsound.m since it's got objective C in it.

Known bugs and glitches:

The Hero_playnotes on a set of 5 notes goes too fast, so there
needs to be a slight delay added between the note of a multi-note
play.

ba5356603a yn()
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.

6e136c6f7d more ATTNORETURN
A recent commit to alloc.c by Keni drew attention to the fact that
there are extern prototypes scattered around in various .c files.
Those can make use of ATTRNORETURN (non-gcc compilers and C23) the
same way the prototypes in extern.h can, and they were overlooked
when ATTRNORETURN was first added.

02a48aa8cf split g into multiple structures
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

Also add a menu entry for nethack's help command to show it during

in config.h since it won't be useful on servers that don't give
players access to command lines.

New genl_display_file() just writes to stdout.  opt_usage(), which
calls it, might need some suid/sgid handling to make sure the output
is done as the player rather than as nethack.

11c8d5cd5e Unix: command line --windowtype:foo fix
initoptions(), including initoptions_finish(), was running to
completion with the default window system before windowtype from the
command was parsed and activated.  When the default window system
is tty without MS-DOS the map type gets set to ascii; command line
--windowtype:X11 doesn't switch it back to the X11 default of tiled.

So,
| NETHACKOPTIONS=windowtype:X11 nethack
ran nethack in tiles mode but
| nethack --windowtype:X11
ran it in text mode (assuming .nethackrc left tiles vs text with the
default setting).

I think this fix is quite iffy but it seems to work as intended....
It reclassifies '--windowtype' as an "early option" in unixmain.c,
and the options.c code ultimately processes it twice.

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.

cb0c21e91d ENHANCED_SYMBOLS
A new feature, enabled by default to maximize testing, but one which can
be disabled by commenting it out in config.h

With this, some additional information is added to the glyphmap entries
in a new optional substructure called u with these fields:
    ucolor          RGB color for use with truecolor terminals/platforms.
                    A ucolor value of zero means "not set." The actual
                    rgb value of 0 has the 0x1000000 bit set.
    u256coloridx    256 color index value for use with 256 color
                    terminals, the closest color match to ucolor.
    utf8str         Custom representation via utf-8 string (can be null).

There is a new symset included in the symbols file, called enhanced1.

Some initial code has been added to parse individual
OPTIONS=glyph:glyphid/R-G-B entries in the config file.

The glyphid can, in theory, either be an individual glyph (G_* glyphid)
for a single glyph, or it can be an existing symbol S_ value
(monster, object, or cmap symbol) to store the custom representation for
all the glyphs that match that symbol.

Examples:
   OPTIONS=glyph:G_fountain/U+03A8/0-150-255

(Your platform/terminal font needs to be able to include/display the
character, of course.)

The NetHack core code does parsing and storing the customized
entries, and adding them to the glyphmap data structure.

Any window port can utilize the additional information in the glyphinfo
that is passed to them, once code is added to do so.

Also, consolidate some symbol-related code into symbols.c, and remove it from
files.c and options.c

cf9e8da56c fix issue #689 - ?: warning
From copperwater:  a recently added use of <test> ? <if> : <else>
had a ptrdiff_t (signed) expression for <if> and a size_t (unsigned)
expression for <else> which triggered a sign-compare warning when
the two expressions are implicitly converted into the same type.

Use casts to convert both expressions to long rather that convert
the size_t half to ptrdiff_t or vice versa.  The final result gets
cast to int already.

45bc2dafa9 Unix command line parsing
Move a bunch of stuff out of main() into new early_options(): '-dpath'
playground directory handling, '-s ...' show scores instead of playing,
and the 'argcheck()' options:  --version, --showpaths, --dumpenums,
and --debug (not to be confused with -D).  Also introduce
| --nethackrc=filename
| --no-nethackrc
to control RC file without using NETHACKOPTIONS so that that is still
available for setting other options.  They can start with either one
or two dashes.  --no-nethackrc is just --nethackrc=/dev/null under the
hood.  '-dpath' can now be '--directory=path' or '--directory path'
but the old syntax should still work.  '-s ...' can be '--scores ...'.

Basic call sequence in unixmain relating to options is now
|main() {
|  early_options(argc, argv[]);
|  initoptions(); /* process sysconf, .nethackrc, NETHACKOPTIONS */
|  process_options(possibly_modified_argc, possibly_modified_argv[]);
|}
Options processed by early_options() that don't terminate the program
are moved to the end of argv[], with argc reduced accordingly.  Then
process_options() only sees the ones that early_options() declines to
handle.

Most early options were using plain exit() instead of nh_terminate()
so not performing any nethack-specific cleanup.  However, since they
run before the game starts, there wasn't much cleanup being overlooked.

chdirx() takes a boolean as second argument but all its callers were
passing int (with value of 1 or 0, so it still worked after being
implicitly fixed by prototype).  Change them to pass TRUE or FALSE.

argcheck() was refusing (argc,argv[]) with count of 1 but then it was
checking 0..N-1 rather than 1..N-1, so it tested whether argv[0] was
an argument instead of skipping that as the program name.  Change to
allow count of 1 with modified argv that has an option name in argv[0].
That happens to fit well with how early_options() wanted to use it.

a1bb10e8f6 unix command line
I wanted to be able to specify -windowtype:foo on the command line so
that I didn't have to use "NETHACKOPTIONS='windowtype:foo' nethack"
and it turned out that such an option already exists, as "-wfoo".
I either never knew about that or had completely forgotten it.  Anyway,
this makes specifying windowtype be more versatile.

"-wX11" still works; now "-w X11", "-windowtype=X11", "-windowtype:X11"
work too, with "--" variations of the latter too also supported.  The
long name can be truncated to any leading substring of "windowtype",
although it has to be at least "wi" for "--"; "--w" is rejected.

Also, any errors reported while processing the command line are
treated like config file processing errors rather than just delivered
with raw_printf().  On tty at least, they used to vanish when the
screen cleared to start the game, with no chance to read them.  Here's
an example from after this change.  It sets windowtype to tty and then
overrides that with X11.

|% ./nethack --w:Qt --win tty -wX11 -windowtype
|
|
| * Unknown option: --w:Qt.
| * Window type [nothing] not recognized.  Choices are:  tty, curses, X11, Qt.
|
|2 errors on command line.
|
|
|Hit return to continue:

This should probably be better integrated with argcheck() or vice
versa but the only change to that was a couple of formatting bits.

Anything that already worked should continue to work just the same,
aside from the improvement to the error feedback.

Blindly suppressing the warning would have silenced it but would

This converts the format to a literal with an additional argument

9bb96322a8 compile NetHack-3.7 without makedefs-generated .h files
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.

This does not take the PR as is.

Unlike the PR, this streamlines and minimizes the integration somewhat:

- use hints/include mechanism instead of creating alternative
  Makefile.dat, Makefile.src, Makefile.top, Makefile.utl in sys/lib;
  those would have been a maintenance nightmare.

- don't have alternative mkmkfile.sh and setup.sh in sys/lib.

- sys/lib/libnethackmain.c differed from sys/unix/unixmain.c by
  very little, so just place a small bit of conditional code at the
  top of sys/unix/unixmain.c instead.

- changed the conditional code bits from __EMSCRIPTEN__ to
  CROSS_TO_WASM.

- You should be able to build the wasm result by:
    cd sys/unix ; sh setup.sh hints/linux.2020 ; cd ../..
    make fetch-lua    (<-one time)
    make WANT_LIBNH all

659b3ce9a7 more unix username (#26 - validating #explore)
I had this in place at one point but must have accidentally undone it
before deciding that yesterday's patch was finished.  Defer fetching
'pw' until it's needed.

80d3abcf00 fix github pull request #26 - validating #explore
Fixes #26

Report stated that the attempt to look up the player's username
(on Unix) failed (reason unknown) and nethack refused to allow the
player to execute the #explore command even though sysconf was set
to use character names (CHECK_PLNAME=1) instead of user names.
Setting EXPLORERS to "*" overcomes this glitch, but the fix moves
a bit of code around to honor CHECK_PLNAME before fetching username
so that that isn't necessary.

I ended up doing some formattng clean up (replace tabs with spaces,
whitespace cleanup in 'port_insert_pastebuf()').  The actual change
to fix #26 is only a few lines.

7054e06e42 NetHack minor release checklist items - savefiles
Make some progress on a couple of next minor release checklist
items, hopefully without introducing too many new bugs. This
is just the initial commit, and work continues.

Checklist items:

Savefiles compatible between Windows versions, whether 64-bit
or 32-bit in little-endian field format.

Selection of file formats:
 historical (structlevel saves),
 lendian (little-endian, fieldlevel saves),
 and just for proof-of-concept, ascii fieldlevel saves
 (the ascii is huge! 10x bigger than little-endian).

For the fieldlevel save, all complex data structures recursively
get broken down until until it is one of the simple types that
can't be broken down any further, and that gets when it gets
written to the output file.

New files needed for this build:

hand-coded:
include/sfprocs.h
src/sfbase.c      - really a dispatcher to one of the
                    output/input format routines.
src/sflendian.c   - little-endian output writer/reader.
src/sfascii.c     - ascii text output writer/reader.

auto-coded (generated):
include/sfproto.h
src/sfdata.c

This is just one approach. I'm sure there are countless others
and they have different pros and cons.

For producing the auto-coded files a utility called
universal-ctags, that is actively maintained and evolving,
was used to do all the heavy-lifting of parsing the
NetHack C sources to tabulate the data fields, and store
them in an intermediate file called util/nethack.tags
(not required for building NetHack if you already have a
generated include/sfproto.h and src/sfdata.c)

util/readtags (also not required for building NetHack
itself) will decipher the nethack.tags file and produce
the functions that can deal with the NetHack struct data
fields.

You can obtain the source for universal-ctags by cloning it
from here:
https://github.com/universal-ctags/ctags.git

The combination universal-ctags + util/readtags has been
tried and tested under both Windows and Linux, so it is
not tied to a particular platform.

Note: util/readtags will work only with universal-ctags
output, so other ctags are unlikely to work as-is.
Universal-ctags can be build from source very easily
under Linux, or under Windows using visual studio.
