Reduce the implied reliance of a specific version of lua.
Instead of copying liblua.a to src/, copy it to lib/. Instead of
telling the compiler to look for headers in lib/lua-5.3.5/src/ as
well as in include/, copy the relevant ones to lib/ and tell the
compiler to look for them there. 'make spotless' in src/ will
remove both the object library and the header files from lib/ but
there really should be a new Makefile.lib to take care of that
directory.
Update Makefile.src to be able to build lua in case someone starts
with 'make all' there instead of in the top Makefile. It doesn't
duplicate the option to fetch the lua source package though.
NHinternal/../genFiles.c has been updated to mention lib/liblua.a
and lib/lua*.h as 'generated at compile time' in Files and to skip
lib/lua-* entirely if it comes across that (so not operating on a
completely clean tree). But it won't be accurate unless/until
other ports stage their lua files there instead of in src/ and
lib/lua-$(VERSION)/src/.
I haven't tried 'make depend' to see what it makes of the numerous
changes....
Unix Makefile.utl wasn't aware of the dependency of makedefs.o on
src/mdlib.c so didn't rebuild makedefs when it should have.
Eliminate several warnings:
mdlib.c - #if inside the arguments to macro Sprintf();
nhlua.c - nhl_error() ends with a call to lua_error() which doesn't
return, but neither of them were declared that way;
nhlsel.c - because of the previous, the 'else error' case of
l_selection_ellipse() led to complaints about uninitialized
variables;
sp_lev.c - missing 'const'.
I did minimal testing which went ok, but revisiting a couple of levels
gave me un-freed memory allocated by restore.c line 1337. (I haven't
looked at that at all.)
A comment in macosx10.14 describing how to create a signed package
had the last sample command wrong. Fix it now in case that part
carries over to hypothetical--but likely--new macosx10.15 hints.
Also, shorten a couple of wide comment lines in the same area.
Add
--showpaths
early option to show where NetHack is expecting to find certain files
without starting up a game. It exits afterwards.
Windows sample (for illustration only, locations may differ for you):
Variable playground locations:
[hackdir ]="C:\Users\JohnDoe\NetHack\3.6\"
[leveldir ]="C:\Users\JohnDoe\AppData\Local\NetHack\3.6\"
[savedir ]="C:\Users\JohnDoe\AppData\Local\NetHack\3.6\"
[bonesdir ]="C:\ProgramData\NetHack\3.6\"
[datadir ]="C:\personal\nhdev\363\test\binary\"
[scoredir ]="C:\ProgramData\NetHack\3.6\"
[lockdir ]="C:\ProgramData\NetHack\3.6\"
[sysconfdir]="C:\ProgramData\NetHack\3.6\"
[configdir ]="C:\Users\JohnDoe\NetHack\3.6\"
[troubledir]="C:\Users\JohnDoe\NetHack\3.6\"
Your system configuration file (in sysconfdir):
"C:\Users\JohnDoe\NetHack\3.6\sysconf"
Your system symbols file (in sysconfdir):
"C:\Users\JohnDoe\NetHack\3.6\symbols"
Your personal configuration file (in configdir):
"C:\Users\JohnDoe\NetHack\3.6\.nethackrc"
Linux (for illustration only, locations may differ for you):
Your system configuration file:
"/home/johndoe/nh/install/games/lib/nethackdir/sysconf"
Your system symbols file:
"/home/johndoe/nh/install/games/lib/nethackdir/symbols"
Your personal configuration file:
"/home/johndoe/.nethackrc"
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.
I had this in place at one point but must have accidentally undone it
before deciding that yesterday's patch was finished. Defer fetching
'pw' until it's needed.
Fixes#26
Report stated that the attempt to look up the player's username
(on Unix) failed (reason unknown) and nethack refused to allow the
player to execute the #explore command even though sysconf was set
to use character names (CHECK_PLNAME=1) instead of user names.
Setting EXPLORERS to "*" overcomes this glitch, but the fix moves
a bit of code around to honor CHECK_PLNAME before fetching username
so that that isn't necessary.
I ended up doing some formattng clean up (replace tabs with spaces,
whitespace cleanup in 'port_insert_pastebuf()'). The actual change
to fix#26 is only a few lines.
Change all the POSTINSTALL 'mkfontdir' to 'mkfontdir -x .lev' although
the mkfontdir version on my system didn't think $(HACKDIR)/*.lev were
font files when I built without dlb.
Also change the PREINSTALL 'cp -n win/X11/nethack.rc ~/.nethackrc' to
keep going if it fails. The linux hints use 'cp -n' for sysconf but
since it is doing so for the playground directory and 'make install'
starts out by clearing away everything in that directory, it shouldn't
fail. But some extra bullet proofing there may be warranted. Only
the initial cp is protected against clobbering an existing file; the
ownership+permission fixups that are applied to the copy of original
file still get applied to an existing one.
travis recently changed linux default dist from trusty to xenial, and bionic is next
include an additional travis linux build under bionic to eliminate surprises there
add a parameter to mkfontdir under linux to prevent it form going after .lev files
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.
Change the test for whether fonts.dir exists (added to the script
in 3.6.0, for automatically setting up possible use of the NH10 font
under X11) from 'test -e file' to 'test -f file' since the latter
seems to be more universally available. When present, fonts.dir is
plain text, so a test for "exists and is a regular file" rather than
one for general existance is appropriate.
