* AutoImportationStatus is 1 if the script should be auto imported when the
|
|
* console opens.
|
|
*
|
|
* FetchedStatus has two purposes:
|
|
* - It is used to detect which scripts are imported in the console, so we can
|
|
* retrieve the correct variables afterwards in the variable box. When a
|
|
* script has been imported, its fetchedStatus value is
|
|
* FetchedStatus::FromConsole.
|
|
* - It is used to prevent circular importation problems, such as scriptA
|
|
* importing scriptB, which imports scriptA. Once we get the variables from a
|
|
* script to put them in the variable box, we switch the status to
|
|
* FetchedStatus::ForVariableBox and won't reload it afterwards. */
