GROOVE

Today GROOVE version 4.4.2 was released. You can get it from the Download page.

Apart from the bug fixes, the new features of this version are:

• The default exploration strategy is now a grammar property, and can be set through the exploration dialog.
• Node colours were extended beyond the type graph:
  * Specify color:name in a rule to change the colour upon rule application.
  * Specify color:name in a host graph to set the initial colouring.
  These colours supersede any colouring specified in the type graph.
• Nodified edges are now rendered as a small dot to improve visualisation.
  Use the new prefix ‘edge:’ in a node of the type graph to indicate that the
  node type represents an nodified edge.
• New textual syntax for attribute manipulation. There are two new prefixes:
  * ‘test:’ that specify a condition for a rule to be applied.
  * ‘let:’ that can be used in rules to modify attributes and in host graphs to
  set the attribute values.
  (See this example grammar for a sample on how to use this new attribute syntax.)
