The tree carried two prebuilt Lua static libraries and a copy of the Lua public headers. lua51.lib is 5.1.2 and matched the headers; lua51.vc9.lib is 5.1.4 and was dead weight — it came second in Ja2_Libraries, so the linker resolved every Lua symbol out of lua51.lib and never pulled an object from it. Just as well, since it asks for /DEFAULTLIB:MSVCRT while we build /MT. ext/lua-5.1.5 is the upstream tarball unmodified, built as lua51 the way the other vendored libraries are, and its src directory replaces lua/ as the home of lua.h, luaconf.h, lauxlib.h and lualib.h. Those four headers were stock 5.1.2 retabbed, so 5.1.5 is bugfix-only against what the game compiled against; the bytecode format is unchanged across 5.1.x and every script under gamedir is plain source anyway. lua/lua.hpp had no includers and returns to etc/ where upstream keeps it. /SAFESEH:NO goes with it. Its two stated reasons were lua51.lib and the smackw32 import library, and both are now gone: every remaining prebuilt static library is SAFESEH-clean (libexpatMT.lib 5 of 5 members with @feat.00 = 0x1, RakNetLibStatic.lib 79 of 79), and lld-link emits a 3155-entry SEHandlerTable without it. The /MT comment blamed the wrong library. lua51.lib carried no linker directives at all; RakNetLibStatic.lib is what pins us to the static runtime, with /DEFAULTLIB:LIBCMT and /DEFAULTLIB:libcpmt. Verified by building all four applications in Debug and Release, and by linking the tarball's own lua.c against our lua51.lib with the build's clang-cl flags and running it under Wine: 5.1 stdlib, GC, coroutines and the x86 __asm fld/fistp lua_number2int fast path all behave. The game itself could not be launched here — this checkout's gamedir has loose Data directories but no SLF archives, so VFS aborts on Data\Ambient.slf long before any script runs.

These are simple tests for Lua. Some of them contain useful code.
|
|
They are meant to be run to make sure Lua is built correctly and also
|
|
to be read, to see how Lua programs look.
|
|
|
|
Here is a one-line summary of each program:
|
|
|
|
bisect.lua bisection method for solving non-linear equations
|
|
cf.lua temperature conversion table (celsius to farenheit)
|
|
echo.lua echo command line arguments
|
|
env.lua environment variables as automatic global variables
|
|
factorial.lua factorial without recursion
|
|
fib.lua fibonacci function with cache
|
|
fibfor.lua fibonacci numbers with coroutines and generators
|
|
globals.lua report global variable usage
|
|
hello.lua the first program in every language
|
|
life.lua Conway's Game of Life
|
|
luac.lua bare-bones luac
|
|
printf.lua an implementation of printf
|
|
readonly.lua make global variables readonly
|
|
sieve.lua the sieve of of Eratosthenes programmed with coroutines
|
|
sort.lua two implementations of a sort function
|
|
table.lua make table, grouping all data for the same item
