Detailed Description

Lua library and scripts.

This module is divided in three parts:

• The C++ files (*.{h,cpp}) are a generic library for C++ ←→ Lua interaction. It provides a convenient, typed interface built on top of Lua's C API that can be used to expose functionality from C++ to Lua and interact with the VM. The main interfaces are described below.
• The Lua files in the lib/ subdirectory are a convenience library built on top of the engine in the main src/ directory. It both wraps the existing components in Lua interfaces and augments them with peripheral, higher-level components.
• The Lua files at the root (*.lua) are a wrapper around the lib/ subdirectory with preset values and functions for common tasks, used mostly in interactive exploratory and debugging sessions.

User types

See register.h for information on how to register and manipulate user types and their meta tables.

Stack

Most of the code is centered around manipulating the Lua data stack, which is done automatically using templates in this module. See the following files for more information:

• get.h: Functions for retrieving values from the stack.
• push.h: Functions for pushing values onto the stack.
• function.h: Operations on callable types, function call implementation.
• table.h: Operations on table values.
• iter.h: Table iteration.
• user.h: Operations on light/full user data values.
• value.h: Operations on generic stack values.
• traceback.h: Functions for printing the call stack.
• utils.h: General utilities for stack manipulation.
