Event System

StatsReporter and LogObserver are replaced by a unified and simplified Event system.

Original Issue: #97

How to use:

# Simple functions serve as listeners

def omitted_listener(node):
    print("Omitted:", node.name)

def started_listener(node):
    print("Started:", node.name)

def finished_listener(node):
    print("Finished:", node.name)


# Connect the listeners
INode.EVENTS['evaluation-omitted'].register(omitted_listener)
INode.EVENTS['evaluation-started'].register(started_listener)
INode.EVENTS['evaluation-finished'].register(finished_listener)

my_node = MyNode()

my_node.evaluate()

# Inspect the node's stats after evaluation
print(my_node.stats) 

>> {"eval_time": 0.123, "start_time": 1573121193} 

Bugfixes

v0.5.7

Bump to v0.5.7

Fixing threading returning too early

Threading will now wait for all nodes to finish evaluation

Unifying the evaluate interface

Revamped the Graph.evaluate interface:

• evaluation modes are now accessible through the mode keyword. Options are linear, threading and multiprocessing

SubOutputs inform their parent when values set

v0.5.4

Bump to version 0.5.4

Enable py3.6 type-hint support for nodes

v0.5.3

Bump version to 0.5.3

Numpy data support

This will alleviate issues with numpy arrays without creating any additional dependencies and should handle a lot more types:
#69

Allow non-json-serializable types

v0.5.1

Update setup.py

Compound Plugs

Compound Plugs are now possible
