When running arc diff master --preview, it fails with:
Error (I003) JSHintI003 ES5 option is now set per default
So I added I003 to .arclint:
"jshint": { "type": "jshint", "include": "(\\.js$|\\.es6$)", "severity": { "I003": "disabled" } },
But it fails:
Exception
Error in parsing '.arclint' file, in key 'severity' for linter 'jshint'.
Unrecognized lint message code "I003". Expected a valid JSHint lint code like "E033" or "W093".
(Run with --trace for a full exception trace.)
