Callback Executor

The Callback Executor allows you to execute an automation function and trigger a callback function upon completion.

Basic Usage

from je_auto_control import callback_executor

result = callback_executor.callback_function(
    trigger_function_name="screen_size",
    callback_function=print,
    callback_param_method="args",
    callback_function_param={"": "Callback triggered!"}
)
print(f"Return value: {result}")

How It Works

The trigger_function_name function executes first.
After it completes, the callback_function is called.
The return value of the trigger function is returned after all callbacks finish.

Parameters

Parameter	Description
`trigger_function_name`	Name of the function to execute (must exist in `event_dict`)
`callback_function`	The function to call after the trigger function completes
`callback_function_param`	Parameters to pass to the callback function (dict)
`callback_param_method`	`"args"` for positional or `"kwargs"` for keyword arguments
`**kwargs`	Additional keyword arguments passed to the trigger function

Extending the Callback Executor

Load external package functions into the callback executor:

from je_auto_control import package_manager

# Add all functions from the 'time' module
package_manager.add_package_to_callback_executor("time")

To inspect the current event dictionary:

from je_auto_control import callback_executor

print(callback_executor.event_dict)

Note

The callback executor’s event_dict should contain the same function mappings as the main executor. If they differ, it is a bug.
