jpanlua

Java bindings to liblua using JEP 398: Foreign Linker API.

Requires JDK 16 or above.

Requires -Dforeign.restricted=permit JRE flag.

Exports package tf.bug.jpanlua under module tf.bug.jpanlua.

usage

running a file

lua_State *L = luaL_newstate();
luaL_openlibs(L);
luaL_dofile(L, "script.lua");
lua_close(L);

// `new Lua(54)` searches for Lua 5.4.
// - On Windows, this means lua54.dll
// - On Linux, this means liblua54.so
//
// On other systems, implementation is dependent on either
// - The dlfcn.h implementation
// - The JVM
Lua lua = new Lua(54);

// LuaState implements AutoClosable
try(LuaState state = lua.newState()) {
    state.openLibs();
    state.doFile("script.lua");
}

assumptions

Below is a list of assumptions put in place due to either JVM limitations or Lua's default configuration. In other words, support is only planned for the intersection of platforms that both mainline Lua is already built to and official versions of JDKs are built to.

• sizeof(intptr_t) == sizeof(size_t) == sizeof(void*)
• LUA_FLOAT_TYPE == double
