Accept input rule file about eslint-generator HOT 2 OPEN

from eslint-generator.

One thing to note here is to track the current status of every rule. Cases to consider:

• I configure some rules, then I import a file. Should the dirty rules override the imported ones or the other way around? Maybe a dialog with "You have changed some rules. Do you want them to be applied in the imported configuration?"

• There are two ways to write a rule. The old one uses an array format. E.g:

  "max-line-length": [true, 120]
  "max-line-length": [true, { "limit": 120 }]
  "max-line-length": [true, { "limit": 120, "ignorePattern": "^(im|ex)port (.*)" }]
  

  The standard format conforms an object with severity? and options?. E.g:

  "max-line-length": {
    "options": { "limit": 120 }
  }
  "max-line-length": { 
    "options" { "limit": 120, "ignorePattern": "^(im|ex)port (.*)" }
  }
  "max-line-length": { 
    "options" { "limit": 120 },
    "severity": "warning"
  }
  "max-line-length": { 
    "options" { "limit": 120, "ignorePattern": "^(im|ex)port (.*)" },
    "severity": "warning"
  }
  

  The question is, should the object format override the array format? Maybe another dialog asking to rewrite the old rules using the object format?
  Maybe every rule could have a status like pristine | imported | dirty where pristine rules won't be added, imported rules won't be touched and dirty rules will be written using the standart format (touching an imported rule and reverted back to its imported value would yield imported status instead of dirty)

What do you think?
