It depends. You can also configure luacheck from within the file you are checking. For instance, in some of my lua code [1], I have:

    -- luacheck: globals init handler
    -- luacheck: ignore 611

The first line tells luacheck that the variables `init` and `handler` are globals, and the second line tells it to ignore lines that contain just whitespace (a quirk the text editor I use uses to manage indenting levels).
