Screen erasure leaves the map set to spaces. If S_unexplored is
something other than <space>, tty wasn't drawing with S_unexplored
after a menu or long message line got erased following temporary
overwrite of part of the map.
This seems to work but is not the correct way to do things.
clear_screen(), cl_eos(), and cl_end() should all be taught to
flag the map as needing to be refreshed after they erase part of it.
tty_clear_nhwindow(WIN_BASE) is also lacking since it erases the
message line, full map, and status lines but leaves their internal
windows with stale data about what is shown instead of marking them
blank.
This adds a pair of new glyphs: GLYPH_UNEXPLORED and GLYPH_NOTHING
GLYPH_UNEXPLORED is meant to be the glyph for areas of the map that
haven't been explored yet.
GLYPH_NOTHING is a glyph that represents that which cannot be seen,
for instance the dark part of a room when the dark_room option is
not set. Since the symbol for stone can now be overridden to
a players choice, it no longer made sense using S_stone for the
dark areas of the room with dark_room off. This allows the same
intended result even if S_stone symbol is mapped to something visible.
GLYPH_UNEXPLORED is what areas of the map get initialized to now
instead of STONE.
This adds a pair of new symbols: S_unexplored and S_nothing.
S_nothing is meant to be left as an unseen character (space) in
order to achieve the intended effect on the display.
S_unexplored is the symbol that is mapped to GLYPH_UNEXPLORED, and
is a distinct symbol from S_stone, even if they are set to the same
character. They don't have to be set to the same character.
Hopefully there are minimal bugs, but it is a deviation from a
fairly long-standing approach so there could be some unintended
glitches that will need repair.
Like lava when that looks the same as water with color Off, render ice
in inverse video if it looks the same as the floor of a room. (I tried
bold first but the result didn't look very good.)
Done for tty and curses; others may want to follow suit.
Something I noticed in the hardfought diff what looked interesting.
Unfortunately the most interesting bit turns out to be unuseable.
Display high altars (Moloch's Sanctum and the Astral Plane) in
bright-magenta and unaligned altars (aside from the Sanctum one) in
red. Hardfought's code also uses white for lawful, gray for neutral,
and black for chaotic, matching the unicorn colors associated with
the alignments. But those colors don't render in a reliable fashion
(see the comment in mapglyph.c) and become confusing about why they're
used for altars of particular alignments.
Performance profiling showed that multiple strcmpi() calls were
occurring each and every time a character was going to the map.
This update:
- honors the WC_COLOR capability
- It allows a window-port to control individual color availability should the window-port wish to do so.
- Makes checking on the individual colors for the active window-port is a straightforward table lookup at the CLR_ offset.
iflags.use_color remains a master on/off switch for use of color, regardless of the capability
compiled into the game (default TRUE).
The has_color() routine, which is now a shared routine in src/windows.c, could likely be made
into a simple macro to eliminate the function call, but this update does not go that far.
This hits a lot of port files due to the window-port interface change, mostly cookie-cutter.
A few symbol-related modifications:
- fulfill a request from a blind player to allow them to
specify a unique/recognizable character for all pets and/or
the player in the config file for use when using a screen
reader (S_player_override, S_pet_override). Requires sysconf
setting ACCESSIBILITY to be set to have an effect, although
they can still be specified in the config file.
- Config file SYMBOLS entries were not working properly on
the rogue level. Allow ROGUESYMBOLS as well as SYMBOLS to be
specified in the config file independently.
- When values are moved into showsyms[], the overriding SYMBOLS
or ROGUESYMBOLS entry from the config file is used if there is
one; if there is no overriding value for a particular symbol,
the loaded symset value is used; if there is no symset entry
loaded for the symbol then a default symbol is used.
If a player names an object with a name that ends in '\\', drops
that object on the floor nearby and does a look at nearby objects,
then the game will crash. This is caused by stack corruption when
the decode loop skips over the decode string terminator.
decode_mixed() writes its output into a 'char *' buffer that's passed
in to it and then returns that buffer. Some excessively paranoid
error checking forced to return 'const char *'. Relax that and use
'char *' so callers can work with the result without extra casts.
Add MG_BW_LAVA to mapglyph() instead of hijacking MG_DETECT. Used
to display lava in inverse video if color is disabled and lava is
using the same display character as water (which is the default).
(The use_inverse option must be enabled for tty to honor it. X11's
text mode doesn't care. Win32 does care but probably shouldn't--it's
not a case like tty where the hardware might not support it.)
This implements both MG_DETECT and MG_BW_LAVA for X11, but only if
the program is built with TEXTCOLOR enabled. Those should work even
when color is not supported, but I suspect that configuration is
unlikely to ever be used so didn't want to spend the time to figure
out how to do it. (The relevant data is overloaded on the color
data, so not available when TEXTCOLOR is disabled.)
The win32 revision is untested.
When underwater, map adjacent lava as lava rather than as "not water".
The Valkyrie quest has lava adjacent to water and the hero ought to
be able recognize it while immersed so she doesn't try to climb out
of water directly into lava.
When the color option is disabled and lava uses the same symbol as
pool or as water (which is the case for default ascii, DECgraphics,
and IBMgraphics), apply the detected-monster display effect to lava.
For tty, this will draw it in inverse video if the use_inverse
option is enabled. (Assumes non-tty will nearly always be using
color so not care.) Creating a separate mapglyph special attribute
for B&W lava instead of overloading MG_DETECT ought to be done but
I didn't want to modify any interface code.
In the midst of composing a commit message about how I reorganized some
of genl_putmixed()'s code without finding any problem, I realized that
there was a problem. The character immediately after \G12345678 would
be copied directly to the output buffer without examination. If that
was the leading backslash for a second encoded sequence, the G and the
hex digits would follow their backslash as just ordinary chars, which
is not what's intended. Or if instead of a backslash the next character
was the input's terminating '\0', the latter would be copied into the
output and the pointer to the input string would be incremented, then
the next loop iteraction would examined whatever followed. If valgrind
is smart enough--and it seems to be--it would complain about accessing
a character that putmixed()'s caller hadn't initialized.
The only use of putmixed() I'm sure about is the what-is code showing
a screen symbol with its explanation, which doesn't exercise either
\G12345678\G12345678 or \G12345678\0. I didn't go hunting to see if
there was someplace that might have an encoded symbol at the end of the
string. what-is still works after this patch....
The only substantive change is adding ``continue'' but I haven't gone
back and undone the reorg that preceded it.
Boulder symbol could not be changed in config file with
"SYMBOLS=S_boulder:0" because the glyph code was checking
iflags.bouldersym; that is only set if boulder symbol
is changed with the deprecated "OPTIONS=boulder:0" way.
Add MG_OBJPILE flag, which windowports can use to check if a location
has more than one object stack. If use_inverse is on, TTY will use
inverse to show such piles. If a boulder is the topmost item on a pile,
then the object pile flag is not used; mainly because boulders are "solid",
boulders dropped by monsters are nearly always over other objects, and so
that special levels such a Sokoban can "hide" items under the boulders.
TODO: a "pilemark", analogous to "petmark", perhaps a green plus sign,
which can be used by windowports with tiles.
I'll push a formatting guide at some point. There may still be
outstanding changes, but please feel free to resolve those as you arrive
a them.
To the best of my knowledge, there is no changes to the actual code
content, but the formatter does have the occasional bug. If you run into
an issue, please fix it!
This reverts commit 7f0f43e6f9 and some related
subsequent commits.
This compiles, but I have not done extensive testing.

There is a lot of code affected by this, and Pat Rankin correctly
observes that it would be better to store roguelike as a level flag
rather than just using Is_rogue_level. A note for the future.
This patch attempts to add some levels of unicode support
to NetHack.
The master on/off switch for any Unicode support is
defining UNICODE_SUPPORT in config.h. Currently
there is code support for two subsets of unicode support:
UNICODE_DRAWING
If UNICODE_DRAWING is defined, then the data
structures used to house drawing symbols are expanded
to the size of wchar_t, big enough to hold unicode characters.
A typdef called `nhsym' is involved and if UNICODE_DRAWING
is defined, it is wchar_t, otherwise it is uchar.
UNICODE_WIDEWINPORT
If UNICODE_WIDEWINPORT is defined, then the data
structures inside the window port are expanded to the size of
wchar_t, big enough to hold unicode characters. Both map
symbols and text within the window port are expanded, in order
for potential support for displaying multinational characters some
day, but this patch only provides viewing of map symbols.
A typdef called `nhwchar' is involved and if UNICODE_WIDEWINPORT
is defined, it is wchar_t, otherwise it is char.
The only window port with code support for UNICODE_WIDEWINPORT
currently is the TTY port. Don't enable UNICODE_WIDEWINPORT
unless:
- it is a TTY port
- the underlying platform specific routines can
handle the larger data structures.
Don't enable UNICODE_SUPPORT unless:
- your compiler can handle wchar_t.
- your compiler can accept L'a' characters.
- your compiler can accept L"wide" strings.
Note that if your compiler can handle the above, you could
enable the larger data structures (currently if TTY) even if your
platform can't actually display unicode or UTF-8, by messing
with u_putch() in win/tty/wintty.c to only deal regular chars.
That should be the only function that actually pushes wide characters
out to the display.
If you enable UNICODE_SUPPORT, and your platform is capable
you will need to turn on the unicode run-time option to be able to
load unicode character sets from the symbol file, to be able to
push unicode characters to the display. You'll also want to load
a unicode symbol set once the unicode option is toggled on. In
a config file you would do that via these two lines:
OPTIONS=unicode
OPTIONS=symset:Unicode_non_US
The repository was stamped with NETHACK_PRE_UNICODE
prior to applying this patch, and stamped with
NETHACK_POST_UNICODE afterwards. The code differences
between those two tagged versions are this patch.
Add putmixed() to the window port. It allows map symbols to
be included in the string by encoding them in a unique fashion.
This was done because Unicode symbols, for instance, could be
longer than the size of a char.
The encoding of the map symbols in this patch is done by
prefixing a glyph value with \GXXXX, where XXXX is a
random value for the current game. The reason for the random
prefix is to minimize the possibility that a player can trigger
the escape sequence processing within text under their control
(dog names, etc.) the way they could if the sequence was fixed
in the source code. The random prefix remains the same throughout
the lifetime of a game because message window strings are
saved in the save file.
(There was actually a bug present because of the embedded
character even before the recent symbol changes, because if
someone was using a different set of characters between games,
the saved messages would reflect the original characters, rather
than the current. That bug was introduced with the ability to
save messages to the savefile.)
A window port does not have to supply an XXX_putmixed() routine,
it can use genl_putmixed() which uses the old behavior of
embedding the sequence as a character within the string
and calling putstr(). genl_putmixed() takes care of the decoding
of the escape sequence.
This also #ifdef's out code in pager.c for converting a glyph
to a character, and uses mapglyph() to do that instead. Does
anyone see a problem with doing that through mapglyph instead
of repeating similar code within pager.c?
Clean up the preprocessing associated with the
loadable symbol stuff.
Base it on new LOADSYMSETS, rather than on the
previously existing ASCIIGRAPH preprocessor define.

Sources tagged before applying NETHACK_PRE_STATUE,
and afterwards with NETHACK_POST_STATUE for easy
rollback.
- reduce the number of symbol tables for each graphics
set {PRIMARY, ROGUESET} from three {map, oc, mon}
tables for each of the display symbols, the loadable symbols,
and the rogue symbols, to one continguous table for
each:
showsyms: the current display symbols
l_syms: the loaded, alterable symbols
r_syms: the rogue symbols
- Modify mapglyph so that the index into the symbolt table is
available as a return value (it was a void function), rather than
just the char converted from the glyph.
- That makes it possible for a window port to use the same
index value to extract from another table (perhaps a unicode
table) for a different set of display symbols. The index
is much more useful than trying to convert the character
into another type of symbol, as some contributed patches
have done.
- It is much easier to load a single alternative flat table to
make substitutions, since the corresponding value just
has to get placed into the same index offset in the
alternative table.
This also fixes a bug I found in botl.c, where you could
go to the rogue level, and the bottom line gold symbol
was not being updated with the new character as it should.
The reason was because the gold value had not changed,
only the field symbol used had changed.
This updates multiple ports to place a (void) cast on
the mapglyph call, now that it returns a value, so this
is going to generate a lot of diff e-mails.

Implement both of the suggestions above.
