GephiStreamer

=============

Python classes for streaming graph to gephi

![Demo](http://matthieu-totet.fr/Koumin/wp-content/uploads/2015/12/GephiStreamDemo.gif)

Install

======

`pip install gephistreamer`

Quick use

======

```python

# Basic import

from gephistreamer import graph

from gephistreamer import streamer

# Create a Streamer

# adapt if needed : streamer.GephiWS(hostname="localhost", port=8080, workspace="workspace0")

# You can also use REST call with GephiREST (a little bit slower than Websocket)

stream = streamer.Streamer(streamer.GephiWS())

# Create a node with a custom_property

node_a = graph.Node("A",custom_property=1)

# Create a node and then add the custom_property

node_b = graph.Node("B")

node_b.property['custom_property']=2

# Add the node to the stream

# you can also do it one by one or via a list

# l = [node_a,node_b]

# stream.add_node(*l)

stream.add_node(node_a,node_b)

# Create edge 

# You can also use the id of the node :  graph.Edge("A","B",custom_property="hello")

edge_ab = graph.Edge(node_a,node_b,custom_property="hello")

stream.add_edge(edge_ab)

```

How to

=====

Use the `Streamer` class to describe the action to perform:

* add_node

* change_node

* delete_node

* add_edge

* change_edge

* delete_edge

Don't forget to have Gephi running with the plugin [Graph Streaming](https://marketplace.gephi.org/plugin/graph-streaming/) installed and active in "Master mode".

GephiWS

=====

The GephiWS class communicates with Gephi as Websocket call. 

GephiREST

=====

The GephiREST class communicates with Gephi as REST call. 

Auto commit

=====

By default, all action will trigger a "commit" and send information to Gephi. You still 

can use the old way by requiering a 

```python

stream = streamer.Streamer(streamer.GephiREST(),auto_commit=False)

[.. actions ..]

stream.commit() # Will send all actions buffered to Gephi 

```
