java_lua
Provides the ability to execute Lua 5.4.3 scripts from Java.
Lua scripts can call registered in a namespace Java functions:
final String script =
"r = java:fn(42, 'xyz')\n" +
"print('call result: ', r) -- prints 100\n" +
"r = ns:func('abc', 42, true, false)\n" +
"print('call result: ', r) -- prints 200\n";
try (final LuaEngine e = new LuaEngine()) {
// register function in the default namespace 'java'
e.registerFunction("fn", (Object... args) -> {
// do something
...
// return call result to the script
return 100;
});
// register external function in the custom namespace 'ns'
e.registerFunction("ns", "func", (Object... args) -> {
// do something
...
// return call result to the script
return 200;
});
// load and execute
e.execute(script);
// ... or load
e.load(script);
// and execute
e.execute();
...
// execute again
e.execute();
}
