Noticed while investigating the message loop. If I had level files
from an interrupted game and was asked "Destroy old game?" when
starting a new one, answering 'n' left the terminal in an unusable
state. Executing 'stty sane' (invisibly since input echo was off)
repaired things but the user shouldn't have to do that.
Change unixtty.c's error() to shut down windowing if that has been
initialized. This might need some tweaking for tty, which will now
clear the screen before showing the startup error message. Other
systems besides unix use unixtty.c so are affected, but I think the
change doesn't introduce anything that should cause trouble (aside
from the potential screen erasure).
Since no one has come up with a better fix for has_colors() being
implicitly declared, add a hack for suppressing a compiler complaint
about has_colors() on linux and/or sco unix that use sufficiently old
<curses.h>.
Report was right after release of 3.6.0 but my fix at the time broke
compile when using more recent <curses.h>.
Since the attempted fix for the warning about has_color() being
implicitly declared introduced a worse problem of conflicting
declaration in cases where it's already declared, back that change
out.
_M_UNIX (SCO UNIX) and __linux__ (all flavors of linux?) both call
has_colors() for TTY_GRAPHICS+TEXTCOLOR configuration, but neither
declared it. The new declaration is just a guess based on usage.
Make the variadic functions look more like ordinary code rather than
have the function opening brace be hidden inside the VA_DECL() macro.
That brace is still there, but VA_DECL() now needs to be followed by
a visible brace (which introduces a nested block rather than the
start of the funciton). VA_END() now provides a hidden closing brace
to end the nested block, and the existing closing brace still matches
the one in VA_DECL().
Sample usage:
void foo VA_DECL(int, arg) --macro expansion has a hidden opening brace
{ --new, explicit opening brace (actually introduces a nested block)
VA_START(bar);
...code for foo...
VA_END(); --expansion now provides a closing brace for the nested block
} --existing closing brace, still pairs with the hidden one in VA_DECL()
This should help if/when another round of reformatting ever takes place,
and also with editors or other tools that do brace/bracket/parenthesis
matching.
I had forgotten that there were variadic functions in sys/* and ended
up modifying a lot more files than intended. The majority of changes
to those just inserted a new '{' line so that revised VA_END()'s '}'
won't introduce a syntax error. A couple of them needed VA_END() moved
so that local variables wouldn't go out of scope too soon. Only the
Unix ones have been tested.
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!
gcc reports "comparison between signed and unsigned". One header file
uses unsigned long for tty flags, another uses [signed] short. 'unsigned'
seems like the best compromise, but this might accidentally introduce lint
for some other configuration.
Clean up the preprocessing associated with the
loadable symbol stuff.
Base it on new LOADSYMSETS, rather than on the
previously existing ASCIIGRAPH preprocessor define.
- Instead of checking for the Rogue level, check which
graphics are engaged (PRIMARY or ROGUESET) in the
SYMHANDLING() macro.
- track which graphics are active through 'currentgraphics'.
- Instead of symset and roguesymset and symhandling and roguehandling
variables, have symset and symhandling be arrays of two, with the
following indexes:
PRIMARY
ROGUESET
That reduced the amount of repeated code.
(Not to be confused with the 'symset' and 'roguesymset' config file options
both of which still exist)
- the symbol routines were adjusted to pass
the index , rather than 'rogueflag' and coding to roguesymset etc.
Other than fixing bugs that are encountered, this is probably
the last of the symbol stuff, with the exception of
making the symset and roguesymset config file options
accept the keyword value "default".
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
