A new feature, enabled by default to maximize testing, but one which can
be disabled by commenting it out in config.h
With this, some additional information is added to the glyphmap entries
in a new optional substructure called u with these fields:
ucolor RGB color for use with truecolor terminals/platforms.
A ucolor value of zero means "not set." The actual
rgb value of 0 has the 0x1000000 bit set.
u256coloridx 256 color index value for use with 256 color
terminals, the closest color match to ucolor.
utf8str Custom representation via utf-8 string (can be null).
There is a new symset included in the symbols file, called enhanced1.
Some initial code has been added to parse individual
OPTIONS=glyph:glyphid/R-G-B entries in the config file.
The glyphid can, in theory, either be an individual glyph (G_* glyphid)
for a single glyph, or it can be an existing symbol S_ value
(monster, object, or cmap symbol) to store the custom representation for
all the glyphs that match that symbol.
Examples:
OPTIONS=glyph:G_fountain/U+03A8/0-150-255
(Your platform/terminal font needs to be able to include/display the
character, of course.)
The NetHack core code does parsing and storing the customized
entries, and adding them to the glyphmap data structure.
Any window port can utilize the additional information in the glyphinfo
that is passed to them, once code is added to do so.
Also, consolidate some symbol-related code into symbols.c, and remove it from
files.c and options.c
Disclaimer: This is a minimal recipe, just to get someone else
started if they have a desire to get a full cross-compile of
NetHack-3.7 going for the Amiga. Some NetHack code bitrot was
corrected, and it does seem able to compile the game itself
to a point. See caveats below.
- If you want to obtain the cross-compiler and tools/libs for Amiga
https://github.com/bebbo/amiga-gcc
To our knowledge, a pre-built copy isn't available, so you have to
obtain the source via git and build it on your system.
The build prerequisite packages for Ubuntu are easily obtained:
sudo apt install make wget git gcc g++ lhasa libgmp-dev \
libmpfr-dev libmpc-dev flex bison gettext texinfo ncurses-dev \
autoconf rsync
The build prerequisite packages for macOS are apparently easily
obtained via homebrew, but that was not tested:
brew install bash wget make lhasa gmp mpfr libmpc flex gettext \
texinfo gcc make autoconf
After installing the prerequite packages and the cross-compiler
it was a straightforward build:
git clone https://github.com/bebbo/amiga-gcc.git
cd amiga-gcc
make update
[Note that you may have to take ownership of the files in the
bebbo repo via chown before succesfully carrying out the next
steps]
make clean
make clean-prefix
date; make all -j3 >&b.log; date
The compiler pieces are installed in /opt/amiga by default which
was satisfactory for our initial attempt, but if you want you can
alter the prefix before you build if you want. That is all
spelled out on the page at: https://github.com/bebbo/amiga-gcc
The Amiga cross-compile can then be carried out by specifying
CROSS_TO_AMIGA=1 on the make command line.
For example:
make CROSS_TO_AMIGA=1 all
make CROSS_TO_AMIGA=1 package
You can explicitly include tty and curses support if desired, otherwise
you'll end up with a tty-only cross-compile build. The SDL1 pdcurses
support has not been tested.
make WANT_WIN_TTY=1 WANT_WIN_CURSES=1 CROSS_TO_AMIGA=1 all
Also note that building the amiga targets using the make command
above, does not preclude you from building local linux or macOS
targets as well. Just drop the CROSS_TO_AMIGA=1 from the make
command line.
The cross-compiler hints additions are enclosed inside ifdef sections
and won't interfere with the non-cross-compile build in that case.
CAVEATS: The original NetHack Amiga build steps included the source for
some utilities that were built and executed on the amiga: txt2iff and
xpm2iff as part of the NetHack build procedure on amiga. Those did not
compile out-of-the-box on the linux host. They will either have to be:
- ported to build and run on the linux or macOS cross-compile host
or
- their functionality will have to be rolled into amiga NetHack
itself and executed on the target Amiga the first time the game
is run, perhaps.
Good luck amiga aficionados, perhaps you'll be able to take this
initial effort forward and get NetHack-3.7 available on the amiga or
amiga-emulator. Let us know if you do, and we can roll changes in
if you provide them.
A check into github issue 364 confirmed that
ba6edbe5dc
had incorrectly updated the bwrite sizeof entry for sysflags.
The SYSFLAGS and MFLOPPY code is all in the outdated part of the tree, so just
remove it rather than re-correct it.
Closes#364Closes#207
Make some progress on a couple of next minor release checklist
items, hopefully without introducing too many new bugs. This
is just the initial commit, and work continues.
Checklist items:
Savefiles compatible between Windows versions, whether 64-bit
or 32-bit in little-endian field format.
Selection of file formats:
historical (structlevel saves),
lendian (little-endian, fieldlevel saves),
and just for proof-of-concept, ascii fieldlevel saves
(the ascii is huge! 10x bigger than little-endian).
For the fieldlevel save, all complex data structures recursively
get broken down until until it is one of the simple types that
can't be broken down any further, and that gets when it gets
written to the output file.
New files needed for this build:
hand-coded:
include/sfprocs.h
src/sfbase.c - really a dispatcher to one of the
output/input format routines.
src/sflendian.c - little-endian output writer/reader.
src/sfascii.c - ascii text output writer/reader.
auto-coded (generated):
include/sfproto.h
src/sfdata.c
This is just one approach. I'm sure there are countless others
and they have different pros and cons.
For producing the auto-coded files a utility called
universal-ctags, that is actively maintained and evolving,
was used to do all the heavy-lifting of parsing the
NetHack C sources to tabulate the data fields, and store
them in an intermediate file called util/nethack.tags
(not required for building NetHack if you already have a
generated include/sfproto.h and src/sfdata.c)
util/readtags (also not required for building NetHack
itself) will decipher the nethack.tags file and produce
the functions that can deal with the NetHack struct data
fields.
You can obtain the source for universal-ctags by cloning it
from here:
https://github.com/universal-ctags/ctags.git
The combination universal-ctags + util/readtags has been
tried and tested under both Windows and Linux, so it is
not tied to a particular platform.
Note: util/readtags will work only with universal-ctags
output, so other ctags are unlikely to work as-is.
Universal-ctags can be build from source very easily
under Linux, or under Windows using visual studio.

Because multiple window ports are supported on Windows
now, even in the same executable and selectable via
config file in some cases, some adjustments became
necessary. There will likely be some further refining
of this over the next day or two.
List of changes:
Move Windows startup from sys/share/pcmain.c and
into its own sys/winnt/windmain.c so that it can
be modified to fix some current breakage, and
allow altering the order of some things.
There is startup processing code that is common to
all of the Windows WindowPorts, but that startup
processing code needs to have no dependency on
any one of those WindowPorts.
Yet, during startup processing, some of the initialization
routines can end up calling NetHack functions that
expect an active Window port underneath, and if there
isn't one, routines like pline, impossible, panic can
end up invoking null function pointers.
Place a new file sys/share/safeproc.c, in which a complete
window port is available for early startup processing
purposes. It's WindowPort name field is set to
"safe-startup" just for reference. The prototypes in
include/winprocs.h require that SAFEPROCS be
Usage:
windowprocs = get_safe_procs(0);
initializes a set of winprocs function pointers that ensure
none of the function pointers are left null, but that's all it does.
windowprocs = get_safe_procs(1);
initializes a set of winprocs functions pointers that ensure
none of the function pointers are left null, but also
provides some basic output and input functionality using nothing
other than C stdio routines (no platform or OS specific code).
The conditional code related to WIN32 has been removed from
sys/share/pcmain.c
The code common to all of the Windows WindowPorts calls
get_safe_procs() almost immediately to ensure that
there is a set of WindowPort winprocs available.
The Windows graphical version in NetHackW.exe is meant to lock
itself to its own windowtype and ignore the OPTIONS=windowtype
setting in the config file, but the code to perform the lock
only did so if (argc > 1).
Moved the code page 437 mapping table to winnt.c so that it could be
used in window and console clients.
Added check that fonts support unicode values we use from code page 437.
Use unicode to draw text if font supports it otherwise use ASCII.
Incorporate some git information into NetHack so that it
is potentially visible to a player. That's useful when
collecting details about the version that they are
running and, if the gitinfo is present, it can tie the
code to a specific git commit in the repository.
This modifies 'makedefs -v' to check for the presence of a data file
called dat/gitinfo.txt and if it is there, parse out its
contents, then write additional lines to include/date.h beyond
what 'makedefs -v' was previously putting in there, similar to
this sample:
#define NETHACK_GIT_SHA "0c84e564c78e2024e562d39539376ce2e21eec8e"
#define NETHACK_GIT_BRANCH "NetHack-3.6.0"
The contents of an appropriate dat/gitinfo.txt are as follows,
and trailing/leading whitespace is not significant:
githash = 0c84e564c78e2024e562d39539376ce2e21eec8e
gitbranch = NetHack-3.6.0
It also adjusts the contents of the 'v' version information to
include the additional git info when available.
Also adds some hooks DEVEL/hooksdir and a perl file to DEVEL
for simplifying and automating the deposit of dat/gitinfo.txt
so that it generally reflects the most current git commit.
DEVEL/gitinfo.pl can be used to build dat/gitinfo.txt at any
time without doing a commit, merge, or checkout.
perl DEVEL/gitinfo.pl
command line --version and -version support
To complement the extra information being provided in the
version by the 'v' command, this also adds support for the
following new command line arguments:
--version
-version Output the NetHack version string then exit.
--version:paste Output the NetHack version string and also copy it to
-version:paste the platform's paste buffer for insertion somewhere,
then exit.
If the paste variation of -version is requested on a platform that
hasn't incorporated any support for the capability, it will deliver
the version info then an error message, prior to exiting.
To support the extended -version:paste variation, a port needs to:
- provide a port-specific routine to perform
the paste buffer copy in a port code file.
- #define RUNTIME_PASTEBUF_SUPPORT in the include/portconf.h header file.
--skeleton--
void port_insert_pastebuf(buf)
char *buf;
{
/* insert code to copy the version info from buf into
platform's paste buffer in a supported way */
}
macosx and Windows have both added support for RUNTIME_PASTEBUF_SUPPORT
Defined strbuf_t and related routines to support dynamically sized
strings. Modified strip_newline() to strip the last newline in a string
instead of the first.
Simplified splash window code using new strbuf_t.
Prior to exiting game, re-enable getreturn and call wait_synch() in
case there is buffered raw prints that must be displayed to user.
If user can make NETHACKOPTIONS point to a file, that user could then
get the file contents via the extended config file error reporting.
Add CONFIG_ERROR_SECURE compile-time option to make that case output
only the first error, no line number or error context.

Related to #H4170, bz274
The current startup code seeks out the SYSCONFPREFIX using:
envp = nh_getenv("COMMONPROGRAMFILES");
which is fine and usually translates to something like
"C:\\Program Files (x86)\\Common Files\\
NetHack then tacks on the NetHack subfolder to the path
"C:\\Program Files (x86)\\Common Files\\NetHack\\"
That should always be the definitive location.
However, in the event that there is no SYSCF_FILE actually
located at that system-wide spot (and ONLY in that event),
fall back to a secondary location of HACKDIR for locating
the SYSCF_FILE.
Also, there's some explicit tweaking added for the Microsoft
visual studio compiler debug execution to all a debug
session to correctly locate things. By default, on a
visual studio build, the executables are linked down in
subfolders of the build directory (Release, or Debug,
depending on visual studio build configuration options).

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".)
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.
currently it's locked behind _MSC_VER, but anything that runs on Win32
should be able to use those functions as long as it has something that
can pass as a debug window.
also, add a non-wildcard-accepting version of showdebug for the dumpit()
functions in dungeon.c and questpgr.c; this makes DEBUGFILES=* workable
without being excruciatingly painful
