Can specify fileType trigger the hook.

Example:

  "pre-commit": {
    "run": ["hint"],
    "fileType": "js|json"
  }

Only commit includes the custom file types can trigger the hook.

It may be very useful in a big project written in multiple languages. :)

It might make more sense to allow specific hooks be ran for extensions instead of applying this to all extensions so you can have a JSHint run only for JS changes and a CSSHint for just css changes.

Yes I agree with you. And how do you think the config will look like ?
Maybe:

  "pre-commit": {
    "run": ["jshint|js,css", "csslint|css", "flake8|py"]
  }

Is that ok?
