I don’t know how picky it is, but if you know the code has the correct syntax it might be it doesn’t like your style. eg.
You are using spaces to indent and it wants tabs.
You are using camelCase names and it wants under_scrores
(or vice-versus)
IMHO having a certain style is important when others are working on the code or you’re sharing the code. Otherwise, if you’re the only one working with the code as long as you have a style you like and are consistant you’ll be fine.
Sorry, I don’t know if Lint has the option of turning of style checking. But definately leave syntax checking on.
