Game is playable, and should compile on linux and Windows.
Assumes you have a lua 5.3 library available.
Removes level compiler and associated files.
Replaces special level des-files with lua scripts.
Exposes some NetHack internals to lua:
- des-table with commands to create special levels
- nh-table with NetHack core commands
- nhc-table with some constants
- u-table with some player-specific data (u-struct)
- selection userdata
Adds some rudimentary tests.
Adds new extended command #wizloadlua to run a specific script,
and #wizloaddes to run a specific level-creation script.
nhlib.lua is loaded for every lua script.
Download and untar lua:
mkdir lib
cd lib
curl -R -O http://www.lua.org/ftp/lua-5.3.5.tar.gz
tar zxf lua-5.3.5.tar.gz
Then make nethack normally.
A few symbol-related modifications:
- fulfill a request from a blind player to allow them to
specify a unique/recognizable character for all pets and/or
the player in the config file for use when using a screen
reader (S_player_override, S_pet_override). Requires sysconf
setting ACCESSIBILITY to be set to have an effect, although
they can still be specified in the config file.
- Config file SYMBOLS entries were not working properly on
the rogue level. Allow ROGUESYMBOLS as well as SYMBOLS to be
specified in the config file independently.
- When values are moved into showsyms[], the overriding SYMBOLS
or ROGUESYMBOLS entry from the config file is used if there is
one; if there is no overriding value for a particular symbol,
the loaded symset value is used; if there is no symset entry
loaded for the symbol then a default symbol is used.
Fix a couple of bugs I stumbled across while testing something else.
The sell prompt for a container dropped in a shop had phrasing issues.
This fixes a couple but there are more. The message composition
assumes that contents fall into two categories: those already owned
by the shop and those the shopkeeper is offering to buy from the hero.
But there is a third: stuff the shopkeeper doesn't care about so
won't buy. The count_contents() routine can supply total contents or
shop-owned contents. Subtracting one from the other yields combined
hero-owned without any way to separate out shk-cares and don't-care.
Subject was "display crash while in curses mode". Restoring with
perm_invent set in config file or NETHACKOPTIONS when the save was
made while swallowed (regardless of perm_invent at that time) resulted
in a crash when invalid u.ustuck was referenced before restoration had
done its pointer fixups.
init_nhwindows() is called with perm_invent On;
restgamestate() temporarily turns it Off (3.6.2 restore hack);
if/when update_inventory() gets called, curses notices that the
persistent window has been disabled so it tears down all its windows
in order to redraw the screen without that one;
docrt() sees non-Null u.ustuck and calls swallowed();
swallowed() tries to use the value of that pointer rather than just
Null/non-Null but the value is from the previous game session, not
valid for the current session;
crash.
Make yet another attempt to prevent update_inventory() from being
called during restore. curses won't try to redraw and the crash
won't happen. But the invalid pointer is still lurking (until an
eventual fixup later during restore).
An earlier fix for update_inventory() during restore actually handled
this problem (for the most common trigger, setworn(), but not in
general), so the 3.6.2 behavior is a regression.
phase_of_moon and friday_13th determined using rn2() instead of local
time if fuzzing. Don't reseed using init_random() if fuzzing. Allow
set_random to be called outside of hacklib. rn2_on_display_rng uses
rn2 if fuzzing so that we have a single source of random that we can
ensure is reproducible. Implement rul() that returns a random unsigned
long. Fix bug in fuzzer handling of ntposkey which would cause us to use
unitialized values for x and y. Added command line arguments to allow
auto starting and stopping of fuzzer. Add a logging facility for the
fuzzer to use to record activity. Added some scripts used to automate
fuzzer testing on windows.
Extend support for highlight rules that specify percentages from HP
and spell power to experience level and experience points. For both
of those, the percentage is based on progress from the start of the
current Xp level to the start of the next Xp level. 100% isn't
possible so is used to enable highlighting a special case: 1 point
shy of next level, most likely to occur after losing a level.
This is something I had in mind a long time ago and then forgot all
about until fiddling with the final disclosure of experience points
recently. It turned out to be trickier than expected because it needs
to check whether Xp should have a status update when it hasn't changed
but Exp has gone up. The latter might hit a percentage threshold that
switches to another highlight rule. Fortunately changes to Exp, at
least that aren't part of level gain or loss (which always trigger
status updating), are all funnelled through a single place (I hope).
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.
One of the claims in #H8849 was that a monster which zapped a wand
that the hero had fully identified made hero's knowledge of it revert
to "a wand". That doesn't happen; it had to have been a different
wand which hadn't been seen up close yet. But the hero should lose
track of known number of charges if a wand is zapped outside his/her
view. When implementing that I noticed that a monster playing a fire
horn to burn away slime was using the routine that gives wand
feedback. Add a separate, similar routine for magical horn feedback.
Half this diff is due to moving a naming support routine from mhitm.c
to do_name.c.
Fix a couple of glitches and add an enchancement. The monster
attributes structure left the 'hidden' field uninitialized unless user
specified "hidden". Mimics were being flagged with mon->mundetected
because they pass the is_hider() test but they 'hide' by taking on an
appearance rather than being unseen due to mundetected. hides_under()
monsters fail the is_hider() test, but can become mundetected if there
is at least one object present. Eels/other fish are neither is_hider()
nor hides_under() but can be mundetected at water locations. So alter
'hidden' handling to deal with these various circumstances.
Asking for 'hidden' for any type of creature will result in having its
location be highlighted if it can't be actively seen or detected. So
using '2000 ^G piranha' will fill up the Plane of Water "normally" but
'2000 ^G hidden piranha' will result in a ton of draw-glyph/delay/
draw-other-glyph/delay sequences and take a painfully long time. Moral
of the story: don't combine 'hidden' with a large count unless you
want to spend quite a while watching the level's fill pattern. Turning
off the 'sparkle' option will cut the flashing in half but still take
a long time. If you really need to fill a level with hidden creatures
and can't bear the flashing/highlighting, use blessed potion of monster
detection or #wizintrinsics to have extended detect. Then all created
monsters will be seen so none will trigger location highlighting.
If you create a 'stalker' or 'invisible stalker' or 'invisible <other-
mon>' its location won't be highlighted, but for 'hidden stalker' or
'hidden invisible stalker' or 'hidden invisible <other-mon>' it will
(provided you don't actually see it due to See_invisible or sensemon()).
