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.
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

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.
Credit to <Someone> for #2.

This patch:
- collects all context/tracking related fields from flags
into a new structure called "context."
It also adds the following to the new structure:
- stethoscope turn support
- victual support
- tin support
-better handling of "more" prompt for messages that would have scrolled off the window
-support perm_invent
-menu option to add/remove windows captions
a few plines that were without punctuation. There may be more non-DEBUG
pline or pline-like things that are still missing punctuation. They are
almost impossible to find after the fact, since they could be anywhere,
including in various dat files and functions that pass strings and formats
into other functions that call pline.
- restructured Install.nt quite a bit. It now contains instructions
to build a graphical nethack using NMAKE, too. I merged
the instructions for command line builds, and separated the IDE
build; that made more sense to me. It is shorter, too.
- added some lines to all Makefiles so they now build
NetHackW.exe when GRAPHICAL is "Y", and NetHack.exe
otherwise. I espacially did not test this on Borland.
Previously, the makefiles would always build NetHack.exe.
- changed the IDE files to build NetHackW.exe instead of
nethackw.exe. This is only cosmetic, but consistent with the
other executable.
- made a small change to pcmain.c, as the MinGW linker
cannot decide between main() and WinMain() when both are
present, as explained in <Someone>'s original
message. (I used a #ifndef instead of comments ;-)
The MinGW graphical build indeed seems to work.
1) consolidate all core usage of `errno' in files.c;
2) give more feedback for any failure by create_levelfile or open_levelfile,
similar to what was being done for problems during level change;
3) include trickery info in paniclog (many instances of "trickery" seem to
be due to disk or quota problems rather than user misbehavior...).
The create_levelfile call in pcmain probably ought to be changed to use
error feedback, but in the meantime this should continue working.
Perhaps error() should be modified to update paniclog too, but I didn't
want to go through all its port-specific incarnations making changes.
Allow single character variations in player names
to remain unique in file names by encoding rather
than substituting.
"plnam one", "plnam_one", and "plnam~one" at the
"Who are you?" prompt get unique filenames after this patch.
Since -s doesn't function properly under the WIN32
graphical interface as yet, disable it altogether.
Also clean up nhusage() so that it does work with
the WIN32 graphical interface.
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.

Allow the special level and dungeon compilers to handle input
files which have CR+LF delimited lines. Apparently Cygwin doesn't
convert MSDOS style line ends into newlines the way stdio should
do for text I/O. The resulting unexpected CR characters result in
syntax errors.
And explicitly using '\n' on both the lex and yacc sides of
MAP processing allows removal of the old NEWLINE hack for Mac MPW.
It won't matter what numeric value that character escape sequence
has internally.
This was a tricky one. While the error was ultimately because
he was specifying a non-existant directory in defaults.nh, the
error message lead me to the wrong area until I traced through
with a debugger.
It turns out that an fqn buffer was being re-used before it
was finished being used with the original information in
sys/share/pcunix.c, so the error message listed the
wrong file!
This adds one more buffer and fixes the problem.
Note that it could only affect plaforms with
PREFIXES_IN_USE defined (NOCWD_ASSUMPTIONS
or VAR_PLAYGROUND)
It also alters the WIN32 error message to give them a
hint as to what the problem might be.
