NetHack 3.7.0 work-in-progress -- General information

NetHack 3.7 is an enhancement to the dungeon exploration game NetHack,

which is a distant descendent of Rogue and Hack, and a direct descendent of

NetHack 3.6.

NetHack 3.7.0 work-in-progress is not a release of NetHack. As a .0 version,

and still very early in its development cycle, there has already been changes

made, and there will continue to be many more prior to an eventual release.

The file doc/fixes3-7-0.txt in the source distribution will be updated with

a list of fixes as they are committed.

In short -- there are likely to be bugs. Don't treat NetHack-3.7 branch as

released code, and if stability is paramount, then the most recent

NetHack 3.6.7 release is safest for you.

We're making the .0 work-in-progress available so that you can observe, test

out, and contribute to its development. Constructive suggestions, GitHub pull

requests, and bug reports are all welcome and encouraged.

The file doc/fixes3-7-0.txt in the source distribution has a full list of

bug-fixes included so far, as well as brief mentions of some of the other code

changes. The text in there was written for the development team's own use and is

provided "as is", so please do not ask us to further explain the entries in

that file. Some entries might be considered "spoilers", particularly in the

"new features" section.

Along with the game improvements and bug fixes, NetHack 3.7 strives to make

some general architectural improvements to the game or to its building

process. Among them:

* Remove barriers to building NetHack on one platform and operating system,

for later execution on another (possibly quite different) platform and/or

operating system. That capability is generally known as "cross-compiling."

See the file "Cross-compiling" in the top-level folder for more information

on that.

* Replace the build-time "yacc and lex"-based level compiler, the "yacc and

lex"-based dungeon compiler, and the quest text file processing done

by NetHack's "makedefs" utility, with Lua text alternatives that are

loaded and processed by the game during play.

* Write game savefiles and bonesfiles in a more portable and consistent way

to open up the possibility of utilizing them between different platforms,

such as between your desktop computer and your hand-held device.

* Add support to make the game restartable without exit (a.k.a. "play again"

support). Toward that end, many previously scattered and separate variables

have been gathered into central 'ga' through 'gz' structures in

decl.h/decl.c. That central ability to reinitialize the variables will

benefit the porting effort to some platforms that are under consideration

where "play again" is typical.

Here are some other general notes on the changes in NetHack 3.7 that were not

considered spoilers:

- automatic annotation "gateway to Moloch's Sanctum" for vibrating square

level once that square's location becomes known (found or magic

mapped); goes away once sanctum temple is found (entered or high altar

mapped)

- savefile: add support to deconstruct internal data structures down into

their individual fields and save those fields instead of the entire

struct

- savefile: use little-endian format for fields where that makes a difference

- - - - - - - - - - -

Please read items (1), (2) and (3) BEFORE doing anything with your new code.

1. Unpack the code in a dedicated new directory. We will refer to that

directory as the 'Top' directory. It makes no difference what you

call it.

2. Having unpacked, you should have a file called 'Files' in your Top

directory.

This file contains the list of all the files you now SHOULD

have in each directory. Please check the files in each directory

against this list to make sure that you have a complete set.

This file also contains a list of what files are created during

the build process.

The names of the directories listed should not be changed unless you

are ready to go through the makefiles and the makedefs program and change

all the directory references in them.

3. Before you do anything else, please read carefully the file called

"license" in the 'dat' subdirectory. It is expected that you comply

with the terms of that license, and we are very serious about it.

4. If you are attempting to build NetHack on one platform/processor, to

produce a game on a different platform/processor it may behoove you to

read the file "Cross-compiling" in your Top directory.

5. If everything is in order, you can now turn to trying to get the program

to compile and run on your particular system. It is worth mentioning

that the default configuration is SysV/Sun/Solaris2.x (simply because

the code was housed on such a system).

The files sys/*/Install.* were written to guide you in configuring the

program for your operating system. The files win/*/Install.* are

available, where necessary, to help you in configuring the program

for particular windowing environments. Reading them, and the man pages,

should answer most of your questions.

At the time of the most recent official release, NetHack 3.6, it had

been tested to run/compile on:

Intel Pentium or better running Linux, BSDI

Intel Pentium or better running Windows 10 or 11

Intel-based, or Apple M1, M2, M3 Macs running

macOS 10.11 (El Capitan) to macOS 14 (Sonoma)

(follow the instructions in sys/unix/NewInstall.unx)

Intel 80386 or greater running MS-DOS with DPMI

built via djgpp compiler (native or Linux-hosted cross-compiler)

OpenVMS (aka VMS) V8.4 on Alpha and on Integrity/Itanium/IA64

Previous versions of NetHack were tested and known to run on the

following systems, but it is unknown if they can still build and

execute NetHack 3.6 or NetHack 3.7:

Apple Macintosh running MacOS 7.5 or higher, LinuxPPC, BeOS 4.0

Atari ST/TT/Falcon running TOS (or MultiTOS) with GCC

If you have problems building the game, or you find bugs in it, we recommend

filing a bug report from our "Contact Us" web page at:

https://www.nethack.org/common/contact.html

Please include the version information from #version or the command line

option --version in the appropriate field.

A public repository of the latest NetHack code that we've made

available can be obtained via git here:

https://github.com/NetHack/NetHack

or

https://sourceforge.net/p/nethack/NetHack/

When sending correspondence, please observe the following:

o Please be sure to include your machine type, OS, and patchlevel.

o Please avoid sending us binary files (e.g. save files or bones files).

If you have found a bug and think that your save file would aid in solving

the problem, send us a description in words of the problem, your machine

type, your operating system, and the version of NetHack. Tell us that you

have a save file, but do not actually send it.

You may then be contacted by a member of the development team with the

address of a specific person to send the save file to.

o Though we make an effort to reply to each bug report, it may take some

time before you receive feedback. This is especially true during the

period immediately after a new release, when we get the most bug reports.

o We don't give hints for playing the game.

o Don't bother to ask when the next version will be out or you can expect

to receive a stock answer.

If you want to submit a patch for the NetHack source code via email directly,

you can direct it to this address:

nethack-bugs (at) nethack.org

If a feature is not accepted you are free, of course, to post the patches

to the net yourself and let the marketplace decide their worth.

All of this amounts to the following: If you decide to apply a free-lanced

patch to your 3.6 code, you are welcome to do so, of course, but we won't

be able to provide support or receive bug reports for it.

In our own patches, we will assume that your code is synchronized with ours.

-- Good luck, and happy Hacking --
