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.
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."
- always write plname into save file, no longer conditional
- add 'selectsaved' wincap option to control the display of
a menu of save files for ports/platforms that support it.
- add support for win32 tty using normal nethack menus.
- the win/tty/wintty code is generalized enough that any
tty port could support the option if the appropriate port-specific
code hooks for wildcard file lookups are added to src/file.c
specifically in the get_saved_games() routine. There is posix
code in there from Warwick already, and there is findfirst/findnext
code in there from win32. Warwick has the posix code only
enabled for Qt at present, but with wintty support, that could be expanded
to other Unix environments quite easily I would think.
Here is what the tty support looks like:
NetHack, Copyright 1985-2005
By Stichting Mathematisch Centrum and M. Stephenson.
See license for details.
Select one of your saved games
a - Bob
b - Fred
c - June
d - mine3
e - Sirius
f - Start a new character
(end)
The following files existed in the NetHack SAVEDIR directory
at the time:
ALLISONMI-Bob.NetHack-saved-game
ALLISONMI-Fred.NetHack-saved-game
ALLISONMI-June.NetHack-saved-game
ALLISONMI-mine3.NetHack-saved-game
ALLISONMI-Sirius.NetHack-saved-game
Note that despite the file names, the actual character name
is drawn from the savefile.
The WIN32CON support passes
USER-*.NetHack-saved-game
to findfirst/findnext where USER is your login name of course.
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.
- 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.
This uses pmatch() as a default pattern matcher,
and #defines USER_SOUNDS_REGEX for Qt
to enable the code for regular expressions.
This is enabled for win32tty and win32gui.
Several flags added since 3.4.0 were destined for flags
(to be saved with the game) but were placed in iflags for
savefile compatibility. These include:
boolean lootabc; /* use "a/b/c" rather than "o/i/b" when looting */
boolean showrace; /* show hero glyph by race rather than by role */
boolean travelcmd; /* allow travel command */
int runmode; /* update screen display during run moves */
This patch has no effect unless you define this in your port's
XXconf.h file.
#define SAVEFILE_340_CONVERT /* allow moving of some iflags fields to flags
without destroying savefile compatibility */
Without it, the new flags remain in "iflags." With it, the flags are moved to
"flags" and the structures are converted when the save file is read. There
is no reverse compatibility. If you save the game after conversion, you
can't load the savefile on 3.4.0, only 3.4.1.
The NOCWD_ASSUMPTIONS conditional code allows readonly
parts of NetHack to be separated from areas that require write-access.
This allows the recent panic log needed a prefix.
Add "travel" boolean option to enable/disable travel command.
Add "mouse_support" wincap option to enable/disable mouse.
- When running the win32 tty version full-screen, some people
complained about the square mouse cursor.

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
- set OPTIONS_FILE in ntconf.h so makedefs will use it
- it gets set to either "ttyoptions" or "guioptions" depending on window port
being built
- dlb nhdat creation stuffs both into the dlb file
Add absent prototypes to some core routines.
Also add some port function() to function(void) in some win32 routines.
Also updates the Borland C Makefile for win32.
Fixes:
- menu shortcuts implemented
- most windows close on space (except for menus with
PICK_ANY style)
- "hilite_pet" option is implemented
- map scrolling is improved somewhat (it now scrolls if
the char is within 5 spaces from the edge of the map -
configurable by #define CLIPAROUND_MARGIN)
- added 3 winhack-specific options:
win32_map_mode:[tiles|ascii4x6|ascii6x8|ascii8x8
|ascii16x8|ascii7x12|ascii8x12|ascii15x12
|ascii12x16|ascii10x18|fit_to_screen]=20
win32_align_status:[left|top|right|bottom]
win32_align_message:[left|top|right|bottom]
Note: aligning status window to left or right edge of the screen does
not look good.
