LUI Feature Structures

The LUI feature structure (aka AVM) widget is maybe the most developed of the existing LUI browsers. It attempts to provide a high-performance viewer that facilitates efficient navigation, even for large AVMs. Following is an example of the LUI rendering of a feature structure:

Feature structure representations of lists are displayed in a more conventional form, using angle brackets. For this convenience to work, LUI needs to know about the list-related attributes and types (e.g. FIRST, REST, list, null, et al.) from the underlying grammar. These can be configured by means of the .luirc file; see the LuiRc pages.

The AVM browser allows imploding and exploding sub-structures. Left clicking on type names (in the top left corner of each sub-AVM) will toggle the display state of that sub-structure, i.e. implode on first click and explode again subsequently.
