When setting up an alternate definition for UCHAR_P to accommodate
DEC C's non-ANSI mode(s), leave the default definition to tradstdc.h.
DEC C's VAXC mode will end up expecting 'unsigned char' rather than
either 'int' or 'unsigned int'. Not applicable for Unix but this
makes similar change there as is being made for VMS.
Suppress Isaac64 on VAX were there isn't an easy way to do 64-bit
arithmetic. (Hard way isn't worth it for just an alternate RNG.)
Eliminate or suppress some diagnostics:
1) In strict ANSI mode, DEC C was reporting that '$' in identifier is
an extension (one time for each file in sys/vms/*.c). (It doesn't do
that for the default 'relaxed ANSI' mode.)
2) DEC C uses WIDENED_PROTOTYPES but widens uchar (unsigned char)
differently depending upon the mode it is operating in. (Applies to
Unix as well as VMS; based on documentation rather than testing.)
Update the comment in tradstdc.h about WIDENED vs UNWIDENED_PROTOTYPES.
An old comment in config1.h about a problem with the earliest version
of DEC C was probably based on an incorrect assumption of what was
really going, but I have no way to go back in time to verify that....
The VMS compiler supports C99 and defines __STDC_VERSION__ to the
corresponding value, but it doesn't supply <stdint.h> so isaac64.c
wouldn't compile. It does supply another header containing what is
needed.
Generally, fish should lay their eggs in the water and
not on land, but the game was only allowing the opposite.
Eels are catadromous and lay their eggs in the Sargasso Sea,
not in the dungeon.
This started out as an attempt to document the curses options in the
Guidebook, but I didn't actually get that far. Instead, integrate
the curses options better via more consistent WC/WC2 usage. This
prevents 'guicolor' from showing up as a boolean option for non-curses
interface in curses+other binary.
For curses itself, let 'petattr' be set/reset via 'O'. Also, accept
'Dim' as a possible pet highlight attribute since it already handles
all the other ordinary attributes. I'm not sure what leftline and
rightline highlighting are supposed to do. They were missing for
ncurses (or maybe they're misspelled for PDcurses?) but adding them
didn't produce any visible effect (using TERM=xterm-256color on OSX
with default font/character set).
Not addressed:
1) general confusion about compile-time vs run-time option filtering;
2) curses pet highlighting only works if 'color' option is enabled.
We aren't defining BSD for OSX but we probably should be. This doesn't
go that far, just changes a couple of __APPLE__ for MACOSX (set up in
config1.h) and defines DEV_RANDOM as "/dev/random".
Fixes#177
The monst struct has 'mintrinsics' field which attempts to handle
both mon->data->mresists and extrinsics supplied by worn armor, but
polymorph/shape-change was clobbering the extrinsics side of things.
Potentially fixing that by changing newcham() to use set_mon_data(...,1)
instead of (...,0) solved that but exposed two other bugs. Intrinsics
from the old form carried over to the new form along with extrinsics
from worn armor, and update_mon_intrinsics() for armor being destroyed
or dropped only worked as intended if the armor->owornmask was cleared
beforehand--some places were clearing it after, so extrinsics from worn
gear could persist even after that gear was gone.
So, fixing the set_mon_data() call in newcham() was a no go. This
fixes update_mon_intrinsics() and adopts the suggested code from
github pull request #177 to have mon->mintrinsics only handle worn
gear instead of trying to overload innate intrinsics with that. This
is a superset of that; the flag argument to set_mon_data() is gone
and mon->mintrinsics has been renamed mon->mextrinsics. (The routine
update_mon_intrinsics() ought to be renamed too, but I didn't do that.)
Do late message suppression in a different fashion. Also, there are
more messages than shk taking hero's possessions and guard taking
hero's gold that need to be suppressed if regular message delivery
is no longer possible: "do not pass Go", "you arise from the grave
as a foo", "the corridor disappears", "you are encased in the rock".
Those last two are from vault handling but take place in a convoluted
manner: paygd -> mongone -> grddead -> clear_fcorr.
Extend 'putstr(WIN_MESSAGE, attribute, string)'s attribute so that
'custompline(SUPPRESS_HISTORY, ...)' can work with ^P's message
history like DUMPLOG history, in order to keep autodescribe feedback
and intermediate prompts for multi-digit count ('Count: 12', 'Count:
123') prompts out of recall history. The old autodescribe behavior
could easily push all real messages out of the recall buffer when
moving the cursor around for getpos, and the count behavior looked
silly for a four or five digit gold count if you set the msg_window
option to 'full' or 'combination' and viewed them all at once.
Other interfaces may want to follow suit, but this doesn't force them
to make any changes. I added a hook for "urgent messages" that might
be rendered in bold or red or some such and/or override the use of
ESC at --More-- from suppressing further messages, but there aren't
any custompline(URGENT_MESSAGE, ...) calls (potentially "You die...",
for instance) to exercise it. Other people have implemented similar
feature it different ways and I'm not sure whether this one is really
the way to go since the core needs to categorize each message that it
deems to be urgent. MSG_TYPE:stop may be sufficent, although MSG_TYPE
matching can entail a lot of regexp execution overhead at run-time.
Fixes#101
If you tell the vault guard your name, drop carried gold, wait one
turn, then pick up the gold again, the guard will move a step away
during the wait. If you teleport away, the guard will seal vault
walls and then park himself on the one-square (so far) temporary
corridor adjacent to the vault wall. Periodically he'll say "Move
along!" and the hero will hear it, regardless of location on the
level. Unless you dig a corridor to rescue him, or one or more of
the vault's walls get breached again, he will never move.
The report emphasized that you could use this to steal the vault's
gold, but it relies on being able to teleport beyond the gaurd's
reach and if you can do that, you might as well do so before the
guard comes. The stranded guard, and him saying "Move along!" when
no longer leading hero out of the vault, are more significant bugs.
Bonus fix: if the game ends and the guard seals up the vault while
the hero is in a spot that gets fixed up (vault wall or temporary
corridor) don't give the "You are encased in the rock" message if
game end was due to death rather than quit.
The new code provoked several warnings; this fixes one of them.
Moving the declaration of 'rolecount' would have been sufficient,
but I've gone another way.
GCC doesn't set __STDC_VERSION__ for older versions. It is verified to
be set by default on 5.3.0.
Older versions set __INT64_MAX__ though (oldest version tested is
4.5.4).
If compilation with older GCC versions is required, set -std=c99. Even
3.4.6 is supported with this setting.
This is branched from Alex's hallu-rng-stability branch,
with two build corrections (detect.c, zap.c), and merged
with the isaac64 branch that we have ready to go.
Alex's dual rng is supported by setting up the array
of multiple isaac64 contexts.
I stuck with Alex's approach of passing the rng function
name around as the parameter (rng or rn2_on_display_rng)
for the new additional parameter needed for
set_random(), init_random(), reseed_random(),
and init_isaac64().
Rand() was typically defined to random() or to rand().
gcc seems to provide a random() to link to on linux
when sys/share/random.c is linked in, but other platforms
such as Windows got an undefined refence to random()
when RANDOM wasn't defined.
The only direct use seems to be in get_rnd_txt() these
days, in rumors.c
Under the USE_ISAAC64 config, neither srandom()
nor srand() are being invoked to seed those routines,
and it really should be using isaac64 when USE_ISAAC64
is defined anyway.
move some system-specific seed-related stuff from hacklib.c to
a system-specific source file and #define SYS_RANDOM_SEED to
utilize it during build.
Windows changes for random seed generation using
crypto next gen (CNG) api routines.
Corresponding vms changes due to disentangling of VMS and
unix when the unix seed bits got moved (untested).

Linux and BSD system have random number source devices that can be used
as source for a unguessable seed source.
Other platforms fall back to generate the seed with gettime().
This is based on the multiple-RNGs code fron NetHack4, but using
only the parts relevant to the display RNG (and with substantial
changes, both because of post-3.4.3 changes, and because Nethack4's
display code is based on Slash'EM's rather than NetHack's).
new domove_core() assessment results
potentially smudge engravings
Proceed to wipe engraving after domove_core() now, but only under
all of the following conditions:
- you can reach the floor
- preceding domove_core() move attempt was marked as
having succeeded in domove_core()
- there is actually an engraving there to impact at
your original spot, or your new spot, or both
Since no one has come up with a better fix for has_colors() being
implicitly declared, add a hack for suppressing a compiler complaint
about has_colors() on linux and/or sco unix that use sufficiently old
<curses.h>.
Report was right after release of 3.6.0 but my fix at the time broke
compile when using more recent <curses.h>.
I did much of this quite some time ago, as prequisite for a different
bug report about monsters vs shades, then set it aside. It ended up
being more complicated than I anticipated.
When deciding whether various non-weapon attacks might hit a shade,
hmonas() was not checking for blessed or silver armor that should have
been applicable. It did check boots when kicking, but not gloves or
rings (when no gloves) when touching, or outermost of cloak/suit/shirt
when hugging, or helmet when head-butting. (The last one is actually
moot because nothing with a head-butt attack is able to wear a helm.)
The problem was more general than just whether attacks might hit and
hurt shades. Various undead and/or demons are also affected by blessed
and/or silver attack but weren't for non-weapon attacks by poly'd hero.
At least two unrelated bugs are fixed: a rope golem's AT_HUGS attack
gives feedback about choking but was fully effective against monsters
which fail the can_be_strangled() test. And it was possible to hug a
long worm's tail, rendering the entire worm immobile.
The report also suggested that all artifacts be able to hit shades for
full effect, but by the time shades are encountered everyone has an
artifact so that would nullify a shade's most interesting ability.
TODO: monster against hero and monster against other monster need to
have similar changes.
Both u_on_rndspot() and losedogs() might result in having a monster
and the hero be at the same location. Have wiz_makemap() use the
same fixup for that as goto_level().
Give the enum lists in several header files explicit values. Adding
or removing new entries will be more tedious, but doing that is rare
and being able to grep the headers for numeric values in addition to
names is very useful.
rm.h also has a bunch of tabs replaced with spaces.
Take a first step towards making the mons[] array be readonly.
The only other place that updates it is when changing succubus and
incubus AD_SSEX attacks to AD_SEDU ones and that can be handled
via existing getmattk(), but so far has proven to be trickier than
anticipated.
They're never modified. Minor complication: &zeroobj is used as
a special not-Null-but-not-an-object value in multiple places and
needs to have 'const' removed with a cast in that situation.
The recent attempt to have looking inside a container show shop
prices had multiple problems. Worst one was showing shop prices as
if the hero would be buying for items already owned by the hero.
Item handling inside containers on shop floor was inconsistent: if
shop was selling those items, they would include a price, but if not
selling--either already owned by hero or shopkeeper didn't care about
them--they were only marked "no charge" if hero owned the container.
This is definitely better but I won't be surprised if other obscure
issues crop up. Gold inside containers on shop floor is always owned
by the shop (credit is issued if it was owned by the hero) but is not
described as such.
Fixes#172
Casting teleport-away via ^T used different requirements for energy,
strength, and hunger than casting it via 'Z'. The strength and hunger
requirements were more stringent, the energy one more lenient. When
it rejected a cast attempt due to any of those, it used up the move,
but 'Z' didn't.
When testing my fix, I wanted an easier way than a debugger to control
how ^T interacts with wizard mode, so finally got around to a first
cut at being able to invoke it via wizard mode but not override those
energy/strength/hunger requirements. It uses the 'm' prefix to ask
for a menu. 'm^T' gives four options about how to teleport. (There
are other permutations which aren't handled.)
Also noticed while testing: ^T wouldn't attempt to cast teleport-away
if you didn't know the corresponding spellbook. 'Z' will attempt that
because it is possible to forget a book and still know its spell.
The 'O' handling for bouldersym was updating the display value for
boulder even if the value had been rejected, and if it still had the
default of '\0', the map would end up with <NUL> characters. (When
examined via '//' or ';', those matched dummy monster class #0 and
led to the impossible "Alphabet soup: 'an("")'" that was suppressed
yesterday.)
Attempting to set bouldersym to ^@ or \0 would also be rejected as
duplicating a monster symbol. That is now accepted and used to reset
the boulder symbol to default. However, other control characters are
also accepted--not due to this patch, they already are, and from a
config file in addition to via 'O'--so bouldersym can still disrupt
the map. But that's no different from putting control characters
into a symbol set or setting them from config file via S_foo:^C.
Fixes#170
Monsters never throw athames or scalpels but some fake player monsters
on the Astral Plane are given those. Since they're stackable the
quantity usually gets boosted but there's no point in having more than
one if they won't be thrown.
This could have been fixed by letting monsters throw those two items,
but I prevented the quantity from being boosted instead.
Player came across a stack of 2 gray stones in a shop and kicked one.
That one ended up with a different (in his case, lower) price once it
was separate. This behavior only applies to non-glass gems which add
a price variation derived from internal ID (obj->o_id) number. Make
splitting stacks always yield the same price per item in the new stack
as was being charged in the old stack by choosing a similar o_id. Do
it for all splits (that can vary price by ID, so just non-glass gems),
not just ones performed inside shops.
He picked up the lower priced one and dropped it back on the original
higher priced one; the combined stack took on the lower price. That
will no longer happen if they come from splitting a stack, but this
fix doesn't address merging with different prices when they start out
as separate stacks. (Unpaid items won't merge in inventory if prices
are different, but shop-owned items will merge on floor.)
