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
Move the new VOID_ARGS and some other argument manipulation stuff
from global.h to tradstdc.h where it feels like a better fit. Make the
definition of VOID_ARGS more general; it should work nearly everwhere
these days even if it is only needed for one configuration. XXXconf.h
can redefine it as empty if necessary.
For MONST_P and OBJ_P, I left "void*" as is but I'm pretty sure that
the lack of space in between the two components was never part of the
issue there. (The Ultrix system I used to have access to is long gone.
It was chugging along on autopilot, effectively defenseless, at the time
a linux box on the same subnet got hacked. It probably would have been
shut down for Y2K anyway if it had lasted til then.)
The latest Micrsoft compilers complain when a function is
assigned to a function pointer, and the function's argument
list does not match the prototype precisely.
It was evem complaining about the difference between this:
int x()
{
[...]
}
and a prototype of
int x(void);
when assigning that function's address to a function pointer.
This quiets those warnings, without suppressing the mismatch
check altogether for more serious mismatches.
o Add support for zlib compression via ZLIB_COMP in config.h (ZLIB_COMP
and COMPRESS are mutually exclusive).
o rlecomp and zerocomp are run time options available if RLECOMP and
ZEROCOMP are defined, but not turned on by default if either COMPRESS
or ZLIB_COMP are defined.
o Add information to the save file about internal compression options
used when writing the save file, particularly rlecomp and zerocomp
support.
o Automatically adjust rlecomp and zerocomp (if support compiled in)
when reading in an existing savefile that was saved with those options
turned on. Still allows writing out of savefile in preferred format.
o In order to support zlib and not conflict with compress and uncompress
routines there, the NetHack internal functions were changed to
nh_uncompress and nh_compress as done in the zlib contribution received
in 1999 from <Someone>.
I tagged the sources NETHACK_3_5_0_PREZLIB prior to applying these
changes.
-Allow overriding of OPTIONS_FILE in makdefs.c
-Change obsolete WIN32_GRAPHICS to the correct MSWIN_GRAPHICS
-Remove the 8514 and VESA screen control stuff since it never existed.

-Adds Rogue-level ascii support.
-Also removes unicode support.
Some other build script tweaks as well.
