The JSON output is not very useful for me without the line number. I don't want to have to parse it from the message.

Is this the right way of doing it?

With PR:
```
[
    {
        "file": "",
        "line": 13,
        "valid": false,
        "message": "Unable to parse at line 13 (near \"sdf \")."
    }
]
```

Before:
```
[
    {
        "file": "",
        "valid": false,
        "message": "Unable to parse at line 13 (near \"sdf \")."
    }
]
```
