Whenever a lua script references a core struct obj, increment a counter
in the obj struct. Core code will not free the obj, if there are any
lua references pointing to it, just makes it free-floating.
When lua script ends, the lua gc will free the free-floating objects.
Also exposes u.inventory to lua.
Breaks save and bones compat.
groundwork only - window port interface change
This changes the last parameter for add_menu() from a boolean
to an unsigned int, to allow additional itemflags in future
beyond just the "preselected" that the original boolean offered.
There shouldn't be any functionality changes with this groundwork-only
change, and if there are it is unintentional and should be reported.
Eliminate a couple of warnings about unused static routines.
That led to a couple of other things.
I hope I got host vs target right in the mdlib.c '#if's.
Copy lib/lua-$(VERSION)/src/liblua.h to lib/lua/ rather than lib/.
Instead of copying any of the header files or telling the compiler
where to find the lua ones, generate include/nhlua.h on the fly and
restrict the knowledge of where they are to it (paths are relative
to include/).
|/* nhlua.h - generated by top Makefile */
|#include "../lib/lua-5.3.5/src/lua.h"
|LUA_API int (lua_error) (lua_State *L) NORETURN;
|#include "../lib/lua-5.3.5/src/lualib.h"
|#include "../lib/lua-5.3.5/src/lauxlib.h"
|/*nhlua.h*/
This might need to be redone (or augmented by having CFLAGS add back
'-I path-to-lua') if some compiler can't find '#include "luaconf.h"'
issued by lua.h.
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.)
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.
