Koala Dot

XT -- A Bundle of Program Transformation Tools

A picture of a Koala specification can be generated with the koala-dot tool. This tool reads a Koala composition, normalizes it and transforms a grapg in DOT format. For vizualization you need to heva ethe GraphViz package installed.

   koala-dot -I <directory with Koala components> \
              -i <top-level component> \
              -n \
              -o graph.dot

With the dot program that is part of GraphViz, you can turn this graph into different output formats. E.g.,

   dot -Tps graph.dot > graph.ps

The elements in the graphs (like the one on the right) have to following meaning:

module	present module	yellow box
	normal module	green box
component		pink/orange box
	reachable component	asterix (*) attached to name
interface	provides interface	blue triangle
		a connected provides interfaces has an asterix (*) attached to its name
	requires interface	blue triangle
	private interface	blue diamond
	optional interface	Dashed triangle
switch		red box
		outgoing red arrows correspond to interface references from switch expression.
		The incomming edges correspond to the in cables, the outgoing edges correspond to out edges.
		The top label indicates the switch expression, the bottom labels correspond to switch conditions.
cable	normal	arrow
	transitive	dashed arrow

Normalization steps can be turned on by omitting the '-n' switch (see below).
