Let's experiment with this via our local Gruntfile. If it works fine we can install it in Jenkins (similar to node-csslint). Verify through $ npm install && npm test; Fixed all outstanding violations. Also: * Added syntaxhighight to ignore. * Added imetests (which contain unformatted JSON) to ignore. * In ve.dm.ModelRegistry#matchTypeRegExps, removed redundant !! cast from the [+!!withFunc] statement which was hitting a bug in node-jscs. All callers to this local private function pass a literal boolean true/false so no need to cast it. * Removed "/* key .. , value */" from ve.setProp, though this wasn't caught by node-jscs, found it when searching for " , ". * Made npm.devDependencies fixed instead of using tilde-ranges. This too often leads to strange bugs or sudden changes. Fixed them at the version they were currently ranging to. Bug: 54218 Change-Id: Ib2630806f3946874c8b01e58cf171df83a28da29
