This helps avoid a potential chicken-and-egg scenario
with the system configuration file (sysconf).
If sysconf wasn't accessible at the expected location, it
caused an immediate exit, without relaying any helpful
information. That happened even when using:
'nethack --showpaths'
That's particularly unhelpful, because the --showpaths
output might have been useful towards understanding where
NetHack was looking for such things.
That left you without an easy recourse to identify where
the game is looking for the sysconf file. That might be
especially troublesome if you didn't build the game
yourself.
There was a transcription error in the comments in cstd.h for
the standard list of header files, where only the description
remained for <stdlib.h>, not the name of the file itself.
Remove several extraneous inclusions of the standard C99 headers.
Tested on the following afterwards:
Linux (using hints/linux.370) including tty, curses, qt6, and X11
macOS (using hints/macOS.370) including tty, curses, qt5, and X11
Windows MSYS2 using sys/windows/GNUmakefile
Windows Visual Studio using sys/windows/Makefile.nmake
msdos cross-compile on Ubuntu using djgpp cross-compiler
The g? structs had a mix of variables that were written to
the savefile, and those that were not.
For better clarity and to distinguish those that end up in
the savefile, relocate some g? variables that get written
directly to the savefile into different structs.
This updates EDITLEVEL, although technically it probably
didn't need to, since savefile contents are not changing.

There are some pointer variables that are heads of chains that were not
moved from 'g?' to 'sv?', because they are not actually written to the
savefile directly, but the objects/monst/trap/lightsource/timer in the
chains they point to are. That can be changed, if desired.

Inspired by self-recover, sort of. Enabled for unix by default; can
be disabled by commenting out '#define CHECK_PANIC_SAVE' in unixconf.h.
When starting the game, if there is no save file to restore and no
lock/level files to recover, check whether a panic save file exists.
If there is one, tell the player that it's there and that it might be
viable, then ask whether to start a new game.
It doesn't convert the panic save into a reconverable one (rename by
nethack, then continue trying to restore) or tell the player how to
make it viable (rename to remove ".e" by game admin), just whether it
is present. If player opts to start a new game, the panic save is
left alone and will trigger the "there's a panic save file" situation
again once the new game finishes and player starts another.

I realized that failed explore-mode authorization on a special-mode
saved game cannot downgrade the game mode further down to a normal game,
because this would dump the player back into a state where she has
completed some part of the game in explore mode but is eligible for the
topten list. This is even more true when the game was formerly a
wizard-mode game. Unforunately, that was the state my previous commits
left the game in.
Instead, if restoring an explore-mode or wizard-mode savegame, and the
player is authorized via sysconf for neither of those modes, fail
restoration entirely and start a new game instead. That's sort of
clunky and there could probably be more explanation provided, but it
should be an exceedingly rare occurance and I'm not sure what
alternative exists that would still honor the EXPLORERS and WIZARDS
restrictions. This shouldn't affect the way they default 'down a mode'
in other circumstances, i.e. the overwhelming majority of situations in
which EXPLORERS authorization is needed/checked.
For the same reason, I realized that the player can't be prompted
whether or not to enter explore mode, if being downgraded from a
no-longer-authorized wizmode save while explore mode is authorized. The
change from wizard mode to explore mode must be mandatory. I have also
switched that up so that it will force the change -- unfortunately, this
has the side effect of allowing the preservation of the save, but it's
more important to make sure a wizard mode game doesn't get reverted to
normal mode. They won't be able to load the save into wizard mode
anyway.
If an unauthorized player requests the game launch in wizard mode, it
will try to put her in explore mode instead. If this happened during
restoration of a previous (normal) saved game, the setting of discover
in wd_message() would bypass iflags.deferred_X, allowing the player to
select to keep the non-explore-mode save file. [Actually, when I tested
it I always got an error when answering yes to the "keep the save file?"
prompt, but that's a problem too...] Because deferred_X was still 1
after this, the pline "You are already in explore mode" would also be
printed following the prompt (when moveloop_preamble() attempted to set
explore mode).
Fix this so that loading a normal game with -D, then failing the
authorization, boots into explore mode via iflags.deferred_X and the
"really enter explore mode?" prompt, as it would have if -X were
specified on the command line to begin with.
The sysconf EXPLORERS list restricting access to explore mode was being
evaluated and used when a player used the #exploremode command in-game,
or when specifying -X or OPTIONS=playmode:explore on the command line
when resuming a normal game, but not when starting an entirely new game.
When SYSCF is avilable, check for authorization early, similar to debug
mode authorization, to restrict access to explore mode to EXPLORERS
under (hopefully) all circumstances.
Now that CHECK_PLNAME is a sysconf option, it can be possible to
authorize wizard mode even if get_unix_pw() fails to return the user's
login name, so I think the call to check_user_string() should go out
either way in case that's what's happening.

1. the application’s main bundle
2. ~/Library/Sounds

welcome.

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.
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.
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.
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
^ ^
Using '-u name' rather than '-uname' was being treated as '--usage'
for any value of 'name'.
'-uname' worked as intended unless name was 'sage' (or leading
substring of it). That's still the case after this fix, where the
space after -u is now necessary for that special case name.
Write up a description of how the command line works on UNIX and put
that in new file dat/usagehlp. Add support for
|nethack --usage | --help | -? | ?
to display it and exit.
Also add a menu entry for nethack's help command to show it during
play. That can be suppressed by uncommenting new '#define HIDE_USAGE'
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.
doc/nethack.6 is already out of date again.
For Unix, set plname[] to the default value (player's username)
before running prscore() for 'nethack -s'. Avoids reference to
mysterious "hackplayer" if no entries are found.
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() */
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.
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
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.
Fixes#689
For the !SYSCF configuration, the command line processing still checks
for a value for maximum number of simultaneous players. The recent
revisions would have accepted a negative value. I don't know whether
anything interesting would have happened if someone did that.
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.
The checking for command line flags --version, --showpath, and one
or two others was inside #if CHDIR. I don't know whether anyone
ever disables that configuration option, but it shouldn't control
whether those flags are handled.
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.
Turning on -Wformat-noliteral for Mac triggered a new warning.
Blindly suppressing the warning would have silenced it but would
also have left a real bug in place. The former format was passing
a string argument to %d format.
This converts the format to a literal with an additional argument
for the non-literal part. It compiles cleanly but I don't know how
to test it, let alone force an error for it to report.
Eliminate a couple of compile warnings produced when DEF_PAGER is
defined: unixmain.c: g.catmore=DEF_PAGER; wintty.c: fd=open(...).
Override its use when DLB is also defined since an external pager
could access 'license' but not 'history', 'opthelp', &c when those
are in the dlb container file.
In the commented out value for DEF_PAGER, show a viable value for
the default configuration these days.
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.
I was looking into adding a confirmation prompt for '!' and it
isn't very promising due to sequencing issues. (The check for
whether '!' is allowed should happen before the prompt about
running it but the latter should take place in the core rather
than in the port code.) In the mean time, I noticed that VMS was
ignoring the SHELLERS value from SYSCF.
Untested implementation of a SHELLERS check on VMS. Even if it
works, it should not be using $USER as the user name to verify.
Tweaks the Unix implementation of check_user_string() but doesn't
switch the testing loop to the simpler version used by VMS which
is derived from the generic users test used by Qt.
roll parts of pr385 into source tree
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
