// GLOBALDB
|
|
//
|
|
// The master world model is allowed to maintain global data structures.
|
|
//
|
|
// Unfortunately, any attempt to put a global data structure into the global
|
|
// environment will fail, because the global environment periodically gets wiped
|
|
// clean by the "source rebuild" procedure (see module 'source').
|
|
//
|
|
// This module creates a safe space where you can put global data structures
|
|
// that won't get wiped out.
|
|
//
|
|
// THE GLOBAL OPERATOR
|
|
//
|
|
// This module adds a new function to lua: "global". Global takes a global data
|
|
// structure name (a string) and returns a table for that global data structure.
|
|
// You can put anything you want into the table.
|
|
//
|
|
// Since you're only allowed to use global data structures in the master world
|
|
// model, any attempt to call "global" in a synchronous world model will
|
|
// result in a 'donotpredict' error.
|
|
