public final class JseBaseLib
extends BaseLib

Subclass of BaseLib and LibFunction which implements the lua basic library functions and provides a directory based ResourceFinder as the Globals.finder.

Since JME has no file system by default, BaseLib implements ResourceFinder using Class.getResource(String). first, then falling back to Class.getResource(String) if that fails. Otherwise, the behavior is the same as that of BaseLib.

Typically, this library is included as part of a call to

 
 Globals globals = JsePlatform.standardGlobals();
 globals.get("print").call(LuaValue.valueOf("hello, world"));
  

For special cases where the smallest possible footprint is desired, a minimal set of libraries could be loaded directly via LuaValue.load(LuaValue) using code such as:

 
 Globals globals = new Globals();
 globals.load(new JseBaseLib());
 globals.get("print").call(LuaValue.valueOf("hello, world"));
  

However, other libraries such as PackageLib are not loaded in this case.

This is a direct port of the corresponding library in C.

public JseBaseLib()

Method Details

call

public LuaValue call(LuaValue modname,
 LuaValue env)

Perform one-time initialization on the library by creating a table containing the library functions, adding that table to the supplied environment, adding the table to package.loaded, and returning table as the return value.

Specifically, extend the library loading to set the default value for Globals.STDIN

Overrides:

call in class BaseLib

Parameters:

modname - the module name supplied if this is loaded via 'require'.

env - the environment to load into, which must be a Globals instance.

Returns:

First return value (this(arg1,arg2)), or LuaValue.NIL if there were none.
