In previous versions of NetHack, setting -DUSE_TILES enabled the tile
support, while setting -DSUPPRESS_GRAPHICS produced a NetHack that
would write its TTY output to standard output, and rely on ANSI.SYS or
similar to do screen control. (USE_TILES is now TILES_IN_GLYPHMAP.)
This change ensures that the current NetHack can be built the same
ways.
One twist is that previous NetHacks would drop all support for graphical
modes when tiles were not supported. Thus sys/msdos/vid{vga,vesa}.c have
very disordered use of TILES_IN_GLYPHMAP. There was no need to check
this. But now, the graphical modes also support Unicode. A non-tiled
build should have the graphical modes, with only the text functions
present, provided that ENHANCED_SYMBOLS is defined.
Some unused and locally used symbols were cleaned up along the way.
The old logic used a negative check to emit an extern declaration for
tparm(). This guarded against old platforms whose curses implementations
did not declare their own functions.
If there are still any platforms left that need this declaration, they
can set TPARM_WORKAROUND to get the old behavior back.
The terminfo entries from the standard ncurses distribution have
peculiar settings for entries supporting 24 bit colors. The direct
entries mix indexed and RGB values into an incompatible mess.
This commit adds a simple workaround for the tty port. Colors are
initialised as if only 8 ANSI colors are available. This does not
affect color customisation from the symsets.
The curses port is affected as well. But I am not yet comfortable to
refactor a large part of the code for an absolute edge case.
Buffer overflows could occur when interacting with containers while
inputting or outputting many items.
This commit ensures topline updates do not exceed buffer limits by
checking against TBUFSZ.
Issue reported by k21971 on IRC.
Originating from https://github.com/NetHack/NetHack/pull/1519,
there was an issue with the pull request's back-end fork or with
the pull request itself.
The code changes were applied manually instead, with credit to the
pull request's author, instead of being directly merged in via the
pull request.
Contributed by @SirWumpus on GitHub.
Also,
- fixed a bit of conditional code in include/unixconf.h, where the
#else clause remained out of reach for non-bsd systems, but was
needed..
- added a disclaimer to the contributed sys/unix/hints/netbsd.500.
The previous fix, while valid, still prompts for input during early
options processing if stdin is a tty. It really shouldn't be doing
that during early options such as --showpaths, so alter the placement
of the program_state.earlyoptions flag within *main().
armorstatus, and terrainstatus
This adds three special status items to show at a glance what the hero
is wielding, wearing, and standing on.
Each of the three items has its own boolean option rather than try to
fix them in with the existing opttional status conditions. After a
lot of testing, I think the weapon and armor ones will prove useful
but the terrain one probably won't be.
Presently it is implemented for tty and curses. When I developed it
six years ago, it was also working for X11 but I'm not able to test
the resurrection of that part so have left it out.
remove the safeproc pseudo-windowport routines from
almost a decade ago.
A very early pass is made through the config file,
seeking out just the interface-related OPTIONS=windowport
and OPTIONS=soundlib and ignoring all other options in the
config file during that early pass, so the windowport
can be activated without the NetHack core initialization
in place that some of the other rcfile OPTIONS require.
Bundles the existing rcfile processing code into rcfile().
New functions to control which rcfile options will be
disregarded in the early config file pass, and which will be
processed:
set_all_options_disregarded();
set_all_options_heeded();
disregard_this_option(opt_xx);
heed_this_option(opt_xx);
Windows calls rcfile_interface_options(), which is
a bundling of a series of function calls to achieve
the desired result.

rcfile_interface_options(void)

allopt_array_init();
set_all_options_disregarded();

The two options are very similar but probably mutually exclusive
except when using look-here and look-into-container (both via ':')
with the default setting for 'sortloot', or with inventory when
'sortpack' has been toggled off.
This removes 'use_menu_glyphs' and changes 'menu_objsyms' from a
boolean to a compound taking six possible values:
| 0: no object symbols in menus,
| 1: append object class symbol to object header lines (same as old
|menu_objsyms boolean),
| 2: include object symbol in menu entry lines for objects (same as
|recently added use_menu_glyphs),
| 3: both 1 and 2,
| 4: display as #2 but only if the menu lacks class header lines,
| 5: if header lines are present, display as #1; if headers are not
|present, then display as #4 (which will implicitly be #2).
Default is #4.
Effectively replaces the options portion of pull request #1406 and
retains the functionality, but not as default for normal menus.
Guidebook.tex is only partially updated. Someone else will need to
finish that.
Pull request from NullCGT: add 'use_menu_glyphs' option to be able
show the object class symbol in menus of objects.

This commit fixes a bit of formatting in wintty.c.
Closes#1406
Remove start_screen() and end_screen() from the
Window-port interface.
They were only ever used by tty, and there was a comment
carried to several window-ports about how they "really
should go away. They are tty-specific"
term_start_screen() and term_end_screen() are part of
terminal/NO_TERMS supporting routines now.
Add a note about NO_TERMS to include/wintty.h for clarity.
Rename tty_startup and tty_shutdown to term_startup() and
term_shutdown(). They are found in termcap.c for !NO_TERMS
like most of the other term_ routines, as well as having
versions for several of the NO_TERMS platforms. They aren't
part of the tty_interface called from the core. The tty
implementation does call and rely on them.
Remove some conditional #ifdef's around term_shutdown()
(formerly tty_shutdown()) and just ensure that all the
tty platforms have an implementation that they can link
with, even if it is just a stub presently.
Put the protype for nethack_exit in extern.h to reduce
maintenance to a single spot, and remove it from other
locations. A warning in the msdos cross-compile led to
this change.
Options processing can be early, even before ttyDisplay is allocated.
If we find that TTY_PERM_INVENT initialization is happening too early,
just set a marker (iflags.perm_invent_pending) to try again a bit later.
The changes in win/share are just to be able to sucessfully
reproduce the original issue on Windows. It was easily reproduced
on Unix, just by building with TTY_PERM_INVENT in include/config.h
and setting OPTIONS=perm_invent in config file.
ENHANCED_SYMBOLS is defined by default in config.h.
The msdos build tried to #undef ENHANCED_SYMBOLS
in tilemap.c, but doing it in there created a mismatch
between the data struct definition for glyph_map in wintype.h
and the initializers generated in tilemap.c
Move the msdos build catch for ENHANCED_SYMBOLS to
one single place in config1.h so that the code and data agree.
gcc has recognized various "magic comments" for white-listing
occurrences of implicit fallthrough in switch statements for
a long time:
The range and shape of "falls through" comments accepted are
contingent upon the level of the warning. (The default level is =3.)
-Wimplicit-fallthrough=0 disables the warning altogether.
-Wimplicit-fallthrough=1 treats any kind of comment as a "falls through" comment.
-Wimplicit-fallthrough=2 essentially accepts any comment that contains something
that matches (case insensitively) "falls?[ \t-]*thr(ough|u)" regular expression.
-Wimplicit-fallthrough=3 case sensitively matches a wide range of regular
expressions, listed in the GCC manual. E.g., all of these are accepted:
/* Falls through. */
/* fall-thru */
/* Else falls through. */
/* FALLTHRU */
/* ... falls through ... */
etc.
-Wimplicit-fallthrough=4 also, case sensitively matches a range of regular
expressions but is much more strict than level =3.
-Wimplicit-fallthrough=5 doesn't recognize any comments.
Plenty of other compilers did not recognize the gcc comment convention,
and up until now the compiler warning for detecting unintended
fallthrough had to be suppressed on other compilers. That's because the code
in NetHack has been relying on the gcc approach, and only the gcc approach.
The C23 standard introduces an attribute [[fallthrough]] for the
functionality, when implicit fallthrough warnings have been enabled.
Several popular compilers already support that, or a very similar attribute
style approach, today, even ahead of their C23 support:
C compiler whitelist approach
--------------------------- -------------------------------------
C23 conforming compilers [[fallthrough]]
clang versions supporting
standards prior to
C23 __attribute__((__fallthrough__))
Microsoft Visual Studio
since VS 2022 17.4.
The warning C5262 controls
whether the implict
fallthrough is detected and
warned about with
/std:clatest. [[fallthrough]]
This adds support to NetHack for the attribute approach by inserting a
macro FALLTHROUGH to the existing cases that require white-listing, so
other compilers can analyze things too.
The definition of the FALLTHROUGH macro is controlled in include/tradstdc.h.
The gcc comment approach has also been left in place at this time.
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.

Related note:
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.
Examples: gi.invent, gm.migrating_objs, gb.billobjs, gm.migrating_mons,
gf.ftrap, gl.light_base, gt.timer_base
Pull request from mkuoppal: avoid integer overflow when user types
digits and they're combined into a number by successively multiplying
intermediate value by 10 and adding new digit. Needed to avoid
triggering undefined behavior if the value overflows the largest
signed integer (actually long int).
This is a much more general fix than the code in the pull request,
which imposed an arbitrary limit for one aspect of tty input.
I'm not convinced that integer.h was the right place to add the new
AppendLongDigit() macro. I may not have caught all the places where
it is needed. files.c accumulates a value from digits but uses
unsigned int, so overflow won't trigger undefined behavior (although
it presumably ends up with a different value than what was intended).
options.c and coloratt.c accumulate smaller integers and have a limit
on the number of digits they'll use, so can't overflow.
Fixes#1254
Honor the objection to an earlier change to tty_curs(), despite the
fact that it seems delusional. Four integer comparisons per cursor
positioning call affect the throughput of cmov(), but only if the
program is built without DEBUG defined?
More analyzer induced hackery. If tty_curs() discovers that the x,y
passed to it are no good, don't use them, even if that results in
the next output being in the wrong place.
The old issue of behaving differently when built with DEBUG defined
versus when it is not defined is fixed in a different way.
For curses, behave like tty by keeping a count of messages issued via
raw_print, then if that is non-zero issue a prompt and require the
player to acknowledge them before it erases the screen. Mainly so
that complaints during RC file processing will be seen.
For tty, force getret() to be an unconditional routine instead of
sometimes a routine, sometimes a macro which calls another routine.
For tty, make hitpointbar blink if current HP falls to the critical
HP threshold. Doesn't require status highlighting. Not changed:
when status highlighting is active, use the HP color but force the
attribute to be inverse (plus blink if the criterium is met) rather
than whatever the HP highlight specifies.
For curses, do the same thing. It used to honor HP attribute for
hitpointbar, now it behaves the same as tty: always inverse, maybe
combined with blink. The new code assumes that inverse and color
can be turned off without turning off active blink in the process.
I had intended to make hitpointbar be a full-fledged status field
(which happens to be rendered on top of title) so that it could be
highlighted differently from hit points (mainly so that one could
highlight up and down changes while the other showed percentages).
This is less versatile than that but much simpler.
Use vi (cursor_invisible) and ve (cursor_normal) to hide and show
cursor, if the terminal supports those. This way on a slower
connection the cursor doesn't jump all over the place when doing
map or menu updates.
Unresolved display issues with rxvt-unicode after the optimizations
dealing with switching between DECgraphics line-drawing character set
and normal character set.
Effectively comment them out rather than revert the commits.
