Manipulate [GEXF file format](https://gexf.net) with Pharo.

## Installation 

```st

Metacello new

  githubUser: 'badetitou' project: 'PharoGEXF' commitish: 'main' path: 'src';

  baseline: 'GEXF';

  load

```

## Usage

### Basic commands

1. Create a gexf element

    ```st

    gexf := GEXF new.

    ```

2. Set metadata

    ```st

    gexf metadata creator: 'Gephi.org'.

    gexf metadata description: 'A Web network'.

    ```

 3. Add nodes

    ```st

    graph := gexf graph.

    node1 := graph createNodeWithId: '0'.

	node1 label: 'Hello'.

	node2 := graph createNodeWithId: '2'.

	node2 label: 'World'.

    ```

4. Connect nodes

    ```st

    node1 connectTo: node2.

    ```

5. Export file

    ```st

    String streamContents: [:stream |

	    (GEXFWriter on: stream)

		    prettyPrinting;

	 	    export: gexf ]

    ```

### Full example to show dependencies of classes from Moose

```st

classes := ((model allWithSubTypesOf: FamixJavaType)  select: [ :d | d isStub not and: [ d isAnonymousClass not ]  ]).

gexf := GEXF new.

gexf metadata creator: 'Gephi.org'.

gexf metadata description: 'my project'.

graph := gexf graph.

dicClassNode := classes collect: [ :class | 

	| node |

	node := graph createNode.

	node label: class mooseName.

	class -> node

	 ] as: Dictionary.

dicClassNode keysAndValuesDo: [ :class :node |

	(class query outgoing dependencies targetsAtScope: FamixTType) do: [ :dep |

		dicClassNode at: dep ifPresent: [ :aDepNode | node connectTo: aDepNode ]

		 ] 

	 ].

'd:/seditRHDep.gexf' asFileReference writeStreamDo:  [:stream |

    (GEXFWriter on: stream)

	    prettyPrinting;

 	    export: gexf ]

```
