NAMEluactl — control kernel Lua states
|luactl||[-cq] create name [desc]|
|luactl||[-cq] destroy name|
|luactl||[-cq] load name path|
|luactl||[-cq] require name module|
DESCRIPTIONThe 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:
- 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.
- Operate quietly i.e. nothing is printed to stdout.
- 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.
- Lua device file.
