Bug 123 Report 4030:
Minor thing I've noticed - if I quit the game, at the "Hit <Enter> to end."
prompt, if I close the window rather than pressing Enter, I get the following:
Bug 138 - #H4045:
"nethack -s" leads to "-s is not supported for the Graphical Interface".
That's wrong.
(The Graphical Interface comes with "nethackw".)
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!

Adjust the code and the command line Makefile so that
you no longer have to choose whether to build the tty
version NetHack.exe, or the gui version NetHackW.exe.
Both will now be built in a single 'nmake install' pass.
This reverts commit 7f0f43e6f9 and some related
subsequent commits.
This compiles, but I have not done extensive testing.

- force time_t to be 32 bits via Makefile. (If struct u gets changed to not
store a time_t field, this can be removed).
- Latest Windows SDK (supporting Vista) causes a warning due to
a prototype in sys/winnt/nttty. Since we don't actually link with that
function and rely on a DLL find procedure at run time, comment out
the prototype. The function is now officially in the SDK in the
windows header files anyway.
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.
The palette option is supposed to be allowed in the config file
without a value for win32 to trigger a load of a predefined
NetHack palette, but that wasn't working.
This fixes that. To prevent the use of any palette modification
code at all, just leave the palette option out of the config
file entirely.
Incorporate part of <Someone>'s changes to address
the main part of bug W343-3.
One other patch yet to come needs to provide a way
to limit the IBMGraphics symbols to various subsets that are
available on some international versions of Windows. Pat
suggested that we not incorporate that patch as is, so I'll be
working on an overhaul of the {DEC|IBM|MACgraphics mechanism.
* Checks for the presence of the Unicode
APIs. If GetVersion() returns the 31st bit set, NetHack is running on
a 95-based version of Windows. The Unicode APIs are not available
and NetHack will revert to the pre-patch behavior. This fix isn't needed
on 95-based Windows anyway.
* Fixes console output for text strings.
The character is converted according to the user's configured IEM code
page and passed to the Unicode version of WriteConsoleOutputCharacter.
* Fixes console output for map symbols.
The character is converted according to a fixed mapping containing
code page 437 plus the symbols in the space from 00 to 1F. A fixed
table is used so that a player using Lucida Console can get full
IBMgraphics (original set, i.e. level 3) regardless of the code page.
A table is used instead of MultiByteToWideChar so that the space from
00 to 1F will be converted correctly; this is necessary for correct
display of the Rogue level.
If you specified one or more palete options in the config file,
but not all 16, you ended up with black for any you didn't
specify - oops.
This patch ensures that the table has a full complement
of 16 colours by initializing it to the windows default colours
just ahead of the first palette option encountered.
As before, if the config file has no palette option in it,
no calls to change the palette are made at all. If the
undocumented method breaks in a future release of
Windows, then avoiding palette options will work
around the problem.
Allow config file entries to adjust win32 console colours.
The following entries in a config file are examples:
OPTIONS=palette:black-0-0-0
OPTIONS=palette:red-210-0-0
OPTIONS=palette:green-80-200-0
OPTIONS=palette:brown-180-100-0
OPTIONS=palette:blue-0-0-200
OPTIONS=palette:magenta-128-0-128
OPTIONS=palette:cyan-50-180-180
OPTIONS=palette:gray-192-192-192
OPTIONS=palette:dark gray-100-100-100
OPTIONS=palette:orange-255-128-0
OPTIONS=palette:bright green-0-255-0
OPTIONS=palette:yellow-255-255-0
OPTIONS=palette:bright blue-100-100-240
OPTIONS=palette:bright magenta-255-0-255
OPTIONS=palette:bright cyan-0-255-255
OPTIONS=palette:white-255-255-255
This uses an undocumented way to adjust the console
colours in a win32 console application. The method and
code snippet used comes from www.catch22.net by James Brown.
This page:
http://www.catch22.net/about.asp
states the following:
"you do not have to pay anything to use the software, and there are no
licencing terms for any sourcecode that you may download from this site.
This means you can freely use any sourcecode or portions of code in
your applications, whether they be free software or professional, retail
products."
The autocompletion was working, but you couldn't tell
because the text was overwritten with blanks. This was
a recent glitch created during fix for other cursor problems.
This brings things much closer to correct operation (I hope).
- The shift to only moving the cursor on input (<Someone>'s
changes) had a lot of complications, among them was
that sometimes, there is no more input. When the program was
exiting, or bombing the cursor synch never got done, so the
final messages could end up strewn any place the cursor
happened to be dwelling.
- There were two competing output systems in use: the
wintty stuff for the game, and the msmsg and error stuff
used by the sys/share/pcsys, sys/share/pctty, and
sys/share/pcunix routines. Those were meant to mimic
output to stdout, where stuff just got sent to a sequential
display. Over time, there were calls mixed in that depended
on the cursor tracked stuff from the core game, so you
really couldn't be sure where things were going to display.
It wasn't as much of an issue before, because the cursor
really did get moved around as expected. Everything
now ends up in the same output system.
- I even found a use of the real putchar() because
sys/share/pcunix didn't #include wintty.h the same
as the other files, and the macro never got defined.
Who knows where that character was being put -
the game certainly couldn't track it.
While everything I knew to be wrong yesterday is
now working, there may be some other glitches
lurking that I haven't discovered yet.
Please: test, test, test.
There were still some significant startup message problems
with win32tty.
I've spent a lot of time in the debugger tracing through them all.
I think I've got them all worked out now, certainly the ones that
I was aware of. There may be some I haven't discovered.
Testing welcomed of course!
This patch also attempts to diagnose the error where someone tries
to execute NetHack directly out of a zip file, and provide
them with a (hopefully) helpful message similar to what we
might end up telling them if they wrote in. If you want
to test that part, you can comment out the line in the
Makefile that adds "dungeon" to nhdat, and delete the nhdat
in your binary and src directories, and "make install".
Then add the value of your TEMP environment variable as a
DATADIR statement in defaults.nh (here's mine):
DATADIR=C:\DOCUME~1\ALLISO~1\LOCALS~1\Temp
The diagnostic code engages if the game fails to open
dungeon. It then checks to see if it the game dir is the
TEMP directory for your system, and if so it prints the
message.
the win32 cursor restriction stuff messed up any
messages displayed during abnormal start conditions
where the window system never got initialized properly.
among them:
- messages relating to lock files or games in progress
- dungeon errors
- early panic messages

changes the colours of the windows tty port so that blue and
bright blue, and cyan and bright cyan are distinguishable. The chief
benefit of this is that floating eyes no longer look like shocking
spheres.
1. Switch to low-level console routines for performance improvements.
2. Instead of moving the cursor around like a real tty, just track the
destination coordinates of where the cursor should be, and
defer the movement until user input is expected.

- Move the code for keystroke handling into its own source file.
- Compile and link it as a dynamic link library.
- Dynamically load the keystroke handler at runtime
- Add support for specifying a different handler in defaults.nh
so that internationalization issues can be dealt with without
rebuilding nethack, just supply alternative handlers in HACKDIR.
The following exported functions need to be present in
the keystroke handler .dll:
ProcessKeystroke - returns an ascii value to NetHack
NHkbhit - allows peeking to see if a key/mouse press is waiting
SourceWhere - returns location for souce code for a keystroke handler
SourceAuthor - returns author information for a keystroke handler
KeyHandlerName - returns the full or short name of the keystroke handling dll.
Provide a way to have a port-specific debug-mode commands
if PORT_DEBUG is defined at build time.
Add a win32 keystroke checking routine to assist debugging
of international keyboards.
Fix a problem with the way NetHack was handling
international keyboards by letting ToAscii() come
up with an input character based on the virtual key,
and the shift and caps lock state.
The problem with the new autocomplete was tracked down to
be the result of differences between different implementations
of backsp(). The differences go all the way back to the
early MSDOS port by the look of it, and the win32,
and Mac tty ports all seemed to pattern themselves after the
MSDOS port for that routine. Apparently, it didn't cause any
harm until now.
The problem is that backsp() sends a character sequence
of 0x08, 0x20, 0x08 on at least those ports, where the Unix
tty code only sends 0x08. So the characters in the new
autocomplete were all being erased from the screen.
This patch only fixes the win32 tty port, so I've left the
conditional code in getline.c for DOS and Mac. I
CTRL+ALT was being treated as a valid ALT-sequence,
so the meta bit was being set on it, letting it slip past this
check in wintty.c "if (!i) i = '\033';"
This overhauls the ALT processing in nttty.c, some of
which was using scancode mappings from the DOS port
needlessly.
