LUACTL(8)               NetBSD System Manager's Manual               LUACTL(8)

NAME
     luactl -- control kernel Lua states

SYNOPSIS
     luactl [-cq]
     luactl [-cq] create name [desc]
     luactl [-cq] destroy name
     luactl [-cq] load name path
     luactl [-cq] require name module

DESCRIPTION
     The luactl program allows the manipulation of Lua states in the kernel.
     Lua states are created using the ``create'' command (see below), Lua
     bindings are provided as modules.  To make a Lua binding available to a
     state, it must be ``required''.  Once a module has been ``required'' by a
     state, it can not be unloaded from memory using the modunload(8) command
     until the state using it has been destroyed.

     Lua code can be loaded from the file system into a state at anytime,
     please note that code loaded into a state is immediately executed.

     When executed without a command, luactl reads information about the Lua
     states and displays it.

     The options are as follows:

     -c      Create a Lua state before executing the command.  This flag is
             used for the require and load commands only, it is ignored for
             all other commands.

     -q      Operate quietly i.e. nothing is printed to stdout.

COMMANDS
     create name [desc]
             Create a Lua state with name name and optional description desc.

     destroy name
             Destroy the Lua state name.

     load name path
             Load Lua code in file path into the Lua state name.  Note that
             the path name must contain at least one path separation character
             (`/').

     require name module
             Let the Lua state name use the bindings provided in module
             module.  This is the equivalent of userland Lua code calling the
             `require' function.

FILES
     /dev/lua  Lua device file.
