SyntaxError: Unexpected token

[dfishburn]

vim-prettier 0.2.3

I have the following JSON:

{
  "URL": { "demoVisualization_comment": "Additional parameters are included: ?tempUnit=F&edgeHost=<ip_or_host_name_of_this_machine>", "securityCertificate": "downloads/test.zip" }
}

If I simply run :Prettier, I get this correct output:

{
  "URL": {
    "demoVisualization_comment":
      "Additional parameters are included: ?tempUnit=F&edgeHost=<ip_or_host_name_of_this_machine>",
    "securityCertificate": "downloads/test.zip"
  }
}

But, if I visually select just this line:

  "URL": { "demoVisualization_comment": "Additional parameters are included: ?tempUnit=F&edgeHost=<ip_or_host_name_of_this_machine>", "securityCertificate": "downloads/test.zip" }

And run: :'<,'>Prettier, I get an error:

demoConfig.json|1 col 8| SyntaxError: Unexpected token

Prettier version:

$ npm i -g prettier
prettier@1.7.4 C:\...\npm\node_modules\prettier

$ node --version
v4.2.1

Note, it is a bit inconsistent.
If I had more lines, sometimes it formats them correctly. I was pruning my JSON lines to try to find a small reproducible example.

Hi @dfishburn,

Thanks for reporting this issue, when sending the selected text to prettier and having it attempt to format it, this relies on the line being sent to be on a valid format that the parser can understand, that's why you get that error since the bellow statement is not a valid JSON format on it's own:

  "URL": { "demoVisualization_comment": "Additional parameters are included: ?tempUnit=F&edgeHost=<ip_or_host_name_of_this_machine>", "securityCertificate": "downloads/test.zip" }
