We want the build to assume the same basic layout as the lua repository.
The sources are immediately at the top of the repository and not in
a subdirectory called 'src'.
recover had deviated somewhat from NetHack in its
file expectations:
1) A couple of 3.7 fields needed to be accommodated.
2) hard-coded file size values had deviated.
The file sizes are now in an added header file named "filesize.h",
which is included at the bottom of config.h.
There will likely be another commit to write the filename size ahead
of the file name so that the precise number of characters can be read,
but since that will break existing saves, it can go in along with another
save-breaking commit.
This commit doesn't not alter savefiles written by nethack so does not
require an editlevel bump. It does alter the read-in expectation in
recover to match the game and this get recover working again.
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.

mingw32-make: *** [Makefile:849: ../binary/NetHack.exe] Error 1
DEFINE_KNOWN_FOLDER is using this particular definition in the mingw
header files:
rather than this one:
So, the known folder values that recent code is using such as
FOLDERID_ProgramData, FOLDERID_LocalAppData, and FOLDERID_Profile are
being declared as external constants.
That is why the error is a link error. We need to include -luuid on
the link command line because those external constants are defined
in uuid.lib.
