Load modules from another package
=================================

It is possible to load [GazeMovementIdentifier](../../../argaze.md/#argaze.GazeFeatures.GazeMovementIdentifier), [ScanPathAnalyzer](../../../argaze.md/#argaze.GazeFeatures.ScanPathAnalyzer), [AOIMatcher](../../../argaze.md/#argaze.GazeFeatures.AOIMatcher) or [AOIScanPathAnalyzer](../../../argaze.md/#argaze.GazeFeatures.AOIScanPathAnalyzer) modules [from another Python package](https://docs.python.org/3/tutorial/modules.html#packages).

To do so, simply prepend the package where to find the module into the JSON configuration file:

```
{
		...
		"gaze_movement_identifier": {
			"my_package.MyGazeMovementIdentifierAlgorithm": {
				"specific_plugin_parameter": 0
			}
		},
		...
		"scan_path_analyzers": {
			"my_package.MyScanPathAnalyzerAlgorithm": {
				"specific_plugin_parameter": 0
			}
		}
		...
		"aoi_matcher": {
			"my_package.MyAOIMatcherAlgorithm": {
				"specific_plugin_parameter": 0
			}
		}
		...
		"aoi_scan_path_analyzers": {
			"my_package.MyAOIScanPathAnalyzerAlgorithm": {
				"specific_plugin_parameter": 0
			}
		}
}
```

Then, load your package from the Python script where the [ArFrame](../../../argaze.md/#argaze.ArFeatures.ArFrame) is created.

```python
import argaze

# Import your own package
import my_package

# Load ArFrame
with argaze.load('./configuration.json') as ar_frame:

	# Print ArFrame attributes
	for module, scan_path_analyzer in ar_frame.scan_path_analyzers.items():
		print('scan path analyzer type:', type(scan_path_analyzer))
```
