flu_binding Module

  1. flu_binding.f90
  2. flu_binding

This module provides the Fortran Lua interface.

It defines a flu_state which encapsulates the Lua state and is used to reference a Lua script. The main content are then the wrapper implementations which ease the usage of the Lua functions declared in the lua_fif module.

Naming follows the Lua API, but replaces the lua_ prefix by flu_.
