I just released FSA::Rules 0.25. This version came about as I returned to the module to handle setting up a PostgreSQL database and found the graphics that it churned out, well, wanting. I wanted a decision tree, but the graphics just had the names of the states for the nodes, and then long question-like labels on the edges. What I wanted instead was for each node to be a question (or a statement about what the node was doing), and for the edges to be simple answers to those questions (or indicators as to the success of the code run in a state).
So I added a new attribute to the state class,
label. You can use this
attribute to say something more about the state. In my case, I used it to store
the question the state asks, or the description of the state’s activities. I
then changed the code that creates the graph to use this attribute in preference
to the state name when creating node labels. The result is a much more natural
decision graph, as you see here
The release features a number of other goodies, including the elimination of a
dependence on the
Clone module, and thus also a big memory savings. There is
now a lot more control over the format of graphs, too. Enjoy!
