This is an overhaul to the NetHack drawing mechanism.
- eliminates the need to have separate lists in drawing.c
for the things and their associated explanations by grouping
those thing together on the same inializer in a struct.
- replaces all of these options: IBMgraphics, DECgraphics, MACgraphics,
graphics, monsters, objects, boulder, traps, effects
- drawing.c contains only the set of NetHack standard symbols for
the main game and a set of NetHack standard symbols for the
roguelevel.
- introduces a symbols file that contains named sets of
symbols that can be loaded at run time making it extensible
for situations like multinational code pages like those reported
by <Someone>, without hardcoding additional sets into the game code.
- symbols file uses names for the symbols, so offsets will not break
when new things are introduced into the game, the way the older
config file uchar load routines did.
- symbols file only contains exceptions to the standard NetHack
set, not entire sets so they are much less verbose than all of
the g_FILLER() entries that were previously in drawing.c
- 'symset' and 'roguesymset' config file options for
preselecting a symbol set from the file called 'symbols'
at startup time. The name of the symbols file is not under the
users control, only the symbol set name desired from within the
symbols file is.
- 'symset' config file option loads a desired symbol set for
everything but the rogue level.
- 'roguesymset' config file option loads a desired symbol set
for the rogue level.
- 'SYMBOLS' config file option allows the user to specify replacement
symbols on a per symbol basis. You can specify as many or as few symbols
as you wish. The symbols are identified by a name:value pair, and line
continuation is supported. Multiple symbol assignments can be made on
the same line if each name:value pair is separated by a comma.
For example:
SYMBOLS = S_bars:\xf0, S_tree: \xf1, S_room:\xfa \
S_fountain:\xf4 \
S_boulder:0
- 'symbols' file has the following structure:
start: DECgraphics
Handling: DEC
S_vwall: \xf8 # meta-x, vertical rule
S_hwall: \xf1 # meta-q, horizontal rule
finish
start: IBMgraphics
Handling: IBM
S_vwall: \xb3 # meta-3, vertical rule
S_hwall: \xc4 # meta-D, horizontal rule
finish
- 'symbols' file added to the source tree in the dat directory
- Port Makefiles/scripts will need to be adjusted to move them into
HACKDIR destination
Fix the problems From a bug report. So having
OPTIONS=IBMgraphcs
OPTIONS=noDECgraphics
would yield an ASCII display instead of showing IBMgraphics, but IBMgraphics
flag in the Options list would falsely show as on. Manually toggling it off
put things back into sync.
Avoiding the false setting is completely trivial. And fixing the
inappropriate override turns out to be easy too, unless I've bungled this.
One thing it does not do is try to warn about attempts to set conflicting
options like
OPTIONS=IBMgraphcs
OPTIONS=DECgraphics
Fixing that seems to be too messy to bother with, particularly since the
game runs ok (leaving the setting handled last in place).
The default symbol for lit and unlit corridors are the same. This makes
the lit_corridor option a no-op where the defaults are used and also means
that using a light scroll/spell a corridor has no obvious effect. To
address that, I special-cased the lit corridor symbol and change its color
to bright white when its the same symbol as the unlit corridor symbol (I
didn't change the default color since I thought that made the lit corridor
look strange using the windows console interface).

- If I set the 'boulder' option, shouldn't I be able to give the
symbol I define for them at the crystal ball "object or
monster symbol" prompt and have it work?
- Could ']' be added as a synonym for 'm', as with genocide?
- set boulder symbol to '3'; use '/' or ';' to examine a
boulder. Result is "unknown creature causing you disquiet
co-located with a boulder" even though there's no warning
glyph '3' there.

part 1 touches core files
ntconf.h changes differ slightly from Yitzhak's original.
Makes Borland happy with current sources.
Hides "rawio" on Graphical Port which doesn't do anything with rawio
This was caused by character set incompatibility between message and map
windows. Apparently, Nethack is using IBM character set (CP 437) but fonts
were create for Windows ANSI codepage. I fixed most of it by changing
character set of the fonts except for the Rogue level. I had to make changes
to src/drawing.c for Rogue level since most of Windows fonts are not capable
of displaying control characters (char. code<0x20)
And of course, disabling IBMGraphics option fixes it all.
