Make ESLint apply rules to only certain file name patterns

Question

Is it possible to configure ESLint in a way that it only applies rules to files that names are matching certain pattern? I know it's possible to have separate rule sheets in directories, but in case the structure is following:

app | |- module1 |     |- module1.js |     |- module1.spec.js | |- module2 |     |- module2.js |     |- module2.spec.js 

And I want a project-wide rules that would only apply to the *.spec.js files. I'd expect to have a setting like

"include-pattern": "*.spec.js" 

in the .eslintrc or any other, simlilar way to specify which filenames should be considered for specific rules.

Updated answer:

Yes, now it's possible. In your example it could look like

{   "rules": {     "quotes": [ 2, "double" ]   },    "overrides": [     {       "files": [ "app/module1/*.js" ],       "excludedFiles": "*.spec.js",       "rules": {         "quotes": [ 2, "single" ]       }     }   ] } 

You can read more at eslint doc page.

Currently this is not supported. But for 2.0.0 version we are actively working on this feature.
