New CLI Option: --select-rule

Hi guys,

We have started to introduce ESLint on a couple of fairly large code bases and the rules we have established generate thousands of errors and warnings 😃

I tend to fix on a rule by rule basis but I find it a bit cumbersome sometimes as I need to copy the rule from the eslintrc.json file, wrap it in a json-like string and paste it to the command line. e.g.:

eslint --rule '{new-cap: [2, {"capIsNewExceptions": ["Q", "Q.Promise", "$.Deferred", "jQuery.Deferred"]}] }' src/

It would be easier if I could just pick a rule from my config (or the compiled config):

eslint --select-rule new-cap

Is there a way to achieve this already? Does that seem a good idea?

Thanks

PS: I’m running the latest ESLint on the 1.x branch

Please note this issue is useful with the --fix option

@rapilabs, I had a similar issue and followed the advice by @platinumazure in #6333. eslint --no-eslintrc --parser-options ecmaVersion:6 --rule no-var:error --fix ., in my case.
