Lua-5.1.4 source code modifications:
1. Applied the patch-lua-5.1.4-2.diff patch
2. Moved the following headers from src/ into include/:
- lua.h
- lualib.h
- lauxlib.h
- luaconf.h
3. Added the include/LuaInclude.h header
4. Made the following adjustments in luaconf.h:
//SPRING#define LUA_NUMBER_DOUBLE
#undef LUA_NUMBER_DOUBLE
//SPRING#define LUA_NUMBER double
#define LUA_NUMBER float
//SPRING#define LUA_NUMBER_SCAN "%lf"
#define LUA_NUMBER_SCAN "%f"
5. Moved the *.c files to *.cpp for C++ compilation
6. Swapped <math.h> includes with "streflop_cond.h" includes (for sync)
6. removed the following files:
Makefile
doc/*
etc/*
test/*
src/lua.c
src/luac.c
7. Changed the return type of lua_toboolean from int to bool to prevent
compiler performance warnings on Visual Studio 2005.
8. Modified lbaselib.cpp:luaB_tostring() and lvm.cpp:luaV_tostring()
so that the tostring() lua function would be sync safe.
9. Undefined (in include/luaconf.h):
LUA_COMPAT_VARARG
LUA_COMPAT_MOD
LUA_COMPAT_LSTR
LUA_COMPAT_GFIND
LUA_COMPAT_OPENLIB
10. Added the following to lua.h (and associated code)
lua_set_fopen()
lua_set_popen()
lua_set_system()
lua_set_remove()
lua_set_rename()
lua_calchash()
lua_pushhstring()
11.
modify lauxlib.cpp::luaL_checknumber and LuaInclude.h::lua_tofloat to
trigger asserts if a Lua script pushes a NaN or Inf onto the stack and
the engine reads it (asserts are disabled for Lua-internal math calls)
