Loaded libraries

Basic Lua

The LuaJIT extensions are fully loaded, and can be used globally. The standard Lua libraries are loaded, and are usable. The require function exists, but isn't recommended as the loading of external DLLs might be difficult to properly accomplish. Loading pure Lua files is fine. The ffi table is loaded globally, there is no need to require it, but it'll work nonetheless. As a side-effect of Luv, Lua-compat-5.3 is loaded.

Dear ImGui

A good portion of ImGui is bound to the Lua environment, and it's possible for the Lua code to emit arbitrary widgets through ImGui. It is advised to consult the user manual of ImGui in order to properly understand how to make use of it. The list of current bindings can be found within the source code. Some usage examples will be provided within the case studies. Additional features and interaction is documented in the rendering page.

OpenGL

OpenGL is bound directly to the Lua API through FFI bindings, loosely inspired and adapted from LuaJIT-OpenCL. Some usage examples can be seen in the CRT-Lottes shader configuration page.

NanoVG

The NanoVG library is mostly bound to the Lua API through FFI bindings, with some additional glue code. More explanation can be found in the rendering page.

Luv

For network access and interaction, PCSX-Redux uses libuv internally, and is exposed to the Lua API through Luv, tho its loop is tied to the main thread one, meaning it'll run only once per frame. There is another layer of network API available through the File API, which is more convenient and faster for simple tasks.

Zlib

The Zlib C-API is exposed through FFI bindings. There is another layer of Zlib API available through the File API, which is more convenient and faster for simple tasks.

FFI-Reflect

The FFI-Reflect library is loaded globally as the reflect symbol. It's able to generate reflection objects for the LuaJIT FFI module.

PPrint

The PPrint library is loaded globally as the pprint symbol. It's a more powerful print function than the one provided by Lua, and can be used to print tables in a more readable way.

Lua-Protobuf

The Lua-Protobuf library is available, but not loaded by default. All of its documented API should be usable straight with no additional work. It has been slightly modified, but nothing that should be visible to the user. There is some limited glue between its API and PCSX's.

luafilesystem

The luafilesystem library is loaded globally as the lfs symbol. It's a library that provides access to the filesystem.

LPeg

The LPeg library is available, but not loaded by default. It's a library that provides a pattern-matching library for Lua, which can be useful to create ad-hoc arbitrary parsers.
