core.handle_async(async_job,parameters,finished)
|
||||
^ execute a function asynchronously
|
||||
^ async_job is a function receiving one parameter and returning one parameter
|
||||
^ parameters parameter table passed to async_job
|
||||
^ finished function to be called once async_job has finished
|
||||
^ the result of async_job is passed to this function

Limitations of Async operations
|
||||
-No access to global lua variables, don't even try
|
||||
-Limited set of available functions
|
||||
e.g. No access to functions modifying menu like core.start,core.close,
|
||||
core.show_path_select_dialog
