## Installing

```shell

npm install merge-vbb-stations

```

## Usage

```js

const analyze = require('merge-vbb-stations')

const s1 = {

	type: 'station',

	id: '900000003174',

	name: 'U Turmstr. (Berlin) [Bus Turmstr.]',

	coordinates: {latitude: 52.5263, longitude: 13.341988},

	weight: 5533.75,

	stops: [

		{

			type: 'stop',

			id: '070101000700',

			name: 'U Turmstr. (Berlin) [Bus Turmstr.]',

			station: '900000003174',

			coordinates: {latitude: 52.5263, longitude: 13.341988}

		}

		// …

	]

}

const s2 = {

	type: 'station',

	id: '900000003104',

	name: 'U Turmstr. (Berlin)',

	coordinates: {latitude: 52.525938, longitude: 13.341417},

	weight: 2408,

	stops: [

		{

			type: 'stop',

			id: '070201092701',

			name: 'U Turmstr. (Berlin)',

			station: '900000003104',

			coordinates: {latitude: 52.525938, longitude: 13.341417}

		}

	]

}

analyze(s1, s2)

```

```js

{

	op: 'merge',

	src: /* s1 */,

	dest: /* s2 */,

	stopName: 'Bus Turmstr.'

}

```

## API

`analyze(station1, station2)` will return either `null` (don't merge) or an object. The object looks like this:

- `op`: right now, this can only be `analyze.MERGE`

- `src`: station to merge from

- `dest`: station to merge into

- `stopName`: which name to use for the stops of `src`; if `null`, use the stops's original name

todo: `s1.coordinates` & `s2.coordinates`
