class PackageManager

check_package(package)

Checks if a package is installed and importable.

Parameters:

package (str) – Package name to check.

Returns:

The imported module if found, None otherwise.

add_package_to_executor(package)

Loads all functions, built-ins, and classes from a package into the main executor’s event_dict.

Parameters:

package (str) – Package name to load.

Functions are added with the naming convention package_function. For example, time.sleep becomes time_sleep.

add_package_to_callback_executor(package)

Loads all functions, built-ins, and classes from a package into the callback executor’s event_dict.

Parameters:

package (str) – Package name to load.

get_member(package, predicate, target)

Retrieves members from a package matching the given predicate and adds them to the target executor.

Parameters:

• package (str) – Package name.

• predicate – Inspection predicate (e.g., isfunction, isclass).

• target – Target executor whose event_dict will be updated.

add_package_to_target(package, target)

Loads functions, built-ins, and classes from a package into the specified target executor.

Parameters:

• package (str) – Package name.

• target – Target executor.

Example:

from je_auto_control import package_manager

# Add 'os' module to the executor
package_manager.add_package_to_executor("os")

# Now you can use os functions in JSON actions:
# ["os_getcwd", {}]
# ["os_listdir", {"path": "."}]
