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.
placebc was triggering an impossible sometimes on the plane of
water
It turned out to be because movebubbles issued an
unplacebc(), but a downstream function called
placebc(), so when movebubbles() issued its own
placebc() there was a problem.
The downstream function that beat movebubbles to the placebc()
turned out to be unstuck(). There could be others.
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
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.

This commit is an attempt to address the complaints about
the orc town variation taking away lots of stuff that is
normally available in mine town. The statement in the level
description says "A tragic accident has occurred in Frontier
Town...It has been overrun by orcs."
The changes in this commit attempt to uphold that premise,
while making things a bit more interesting and perhaps
more palatable for the player.
This update does the following in keeping with the mythos:
- While many of the orcs still remain to wander about the
level, many of the orcs took off deeper into the mines with
some of the stuff that they plundered. You may now be
able to hunt some of it down.
- Adds some appearance of this particular horde of marauding
orcs working as part of a larger collective.
- This evolves the Orc Town mine town variation into a
a feature over multiple levels of The Gnomish Mines,
rather than just the single-level "feature" that it was
previously.
- You may have to work longer and a bit harder for some
things than other mine town variations, but at least with
these changes, there is hope that some of it may be found
elsewhere.
Game mechanics notes (maybe spoily?)
- Add mechanism to place objects into limbo (okay, really
place them onto the migrating_objs list for transferring
between levels etc.) and destine them
to become part of the monster inventory of a particular
species. In this particular usage case, it's using the
M2_ORC flag setting to identify the recipients.
- At present, there is no mechanism in the level compiler
for placing objects onto the migrating objects, nor
with more sophisticated landing logic, so a somewhat
kludgy hard-coded fixup and supporting routines were used.
Some day the need for that might change if additional
capabilities move to the level compiler.
This is a NetHack-3.6.2-beta01 update. Please give it a workout.
Fixes#127
