# Moose2GraphJson

I can export and import any MooseModel in a json format adapted for graph database

## Install

### Stable version

```smalltalk

Metacello new

  githubUser: 'badetitou' project: 'Moose2GraphJson' commitish: 'v1.0.0' path: 'src';

  baseline: 'Moose2GraphJson';

  load

```

### Last version

```smalltalk

Metacello new

  githubUser: 'badetitou' project: 'Moose2GraphJson' commitish: 'main' path: 'src';

  baseline: 'Moose2GraphJson';

  load

```

## Export a model

```smalltalk

'D:/test.json' asFileReference writeStreamDo: [ :stream | (M2GJExporter on: stream) writeMooseModel: aMooseModel ]

```

## Import a model

```smalltalk

(M2GJImporter on: 'D:/ref/to/model.json' asFileReference readStream) 

  model: MooseModel new;

  yourself.

importer import.

importer model name

```

## Import in neo4j

You can load the generated json file with this command

```db

CALL apoc.load.json('file:///test-graph.json') YIELD value

WITH value.nodes AS nodes, value.relationships AS rels

UNWIND nodes AS n

CALL apoc.create.node(n.labels, apoc.map.setKey(n.properties, 'id', n.id)) YIELD node

WITH rels, apoc.map.fromPairs(COLLECT([n.id, node])) AS nMap

UNWIND rels AS r

WITH r, nMap[TOSTRING(r.startNode)] AS startNode, nMap[TOSTRING(r.endNode)] AS endNode

WHERE startNode IS NOT NULL and endNode IS NOT NULL 

CALL apoc.create.relationship(startNode, r.type, r.properties, endNode) YIELD rel

RETURN rel

```

## JSON model format

## Goal

Import and Export Fame model the following format

```json

{

  "name":"modelName",

  "nodes": [

    {

      "id": 3510982, 

      "labels": ["FAMIX.Class"],

      "properties": { "isStub": false, "isInterface": false, "numberOfLinesOfCode": 0, "name": "a" }

    },

    {

      "id": 3510983, 

      "labels": ["FAMIX.Attribute"],

      "properties": { "name": "a1", "hasClassScope": false, "numberOfLinesOfCode": -1, "isStub": false }

    },

    {

      "id": 3510984, 

      "labels": ["FAMIX.Attribute"],

      "properties": { "name": "a2", "hasClassScope": false, "numberOfLinesOfCode": -1, "isStub": false }

    }

  ],

  "relationships": [

    { "type": "parentType", "startNode": 3510983, "endNode": 3510982, "properties": {} },

    { "type": "parentType", "startNode": 3510984, "endNode": 3510982, "properties": {} }

  ]

}

```
