Deep copy metadata

The @node decorator now makes sure the metadata is unique for each node created

Plugs handle re-connections correctly

v0.4.2

Plugs clean up Connections properly if reconnected

Python 2.6 works again

Avoiding dict comprehension

Default arguments

Node takes defaults of the inputs args as values for the plugs

Api improvements to Graphs and Nodes

• Nodes can be added to Graph on creation
• Graph is no longer a Node
• metadata on Nodes is UPDATED not REPLACED
• Rename function to node decorator to Node
• Nodes can be accessed via index on graph
• StatsReporter to receive evaluation stats

Support for python 2.6

• Concept of engines removed
• Testsuite improved
• support for python 2.6
• Cleanup

Flow based programming with Python

Features:

• Api:
  • Create Nodes with arbitrary Inputs and Outputs
  • Node can execute arbitrary python code
  • Nodes can be connected via their inputs and outputs to form a Graph
• Graphs behave like Nodes and can be used within other Graphs
• Graph Evaluation in arbitrary environments (Engines)
• Graph is JSON serializable and deserializable
• Comprehensive string representation for Graph and Nodes
