allow_defined_top in default luacheckrc causes errors in .luacheckrc files

[idbrii]

Using allow_defined_top in the default luacheckrc causes unused global errors in .luacheckrc files.

%LOCALAPPDATA%/Luacheck/.luacheckrc:

allow_defined_top = true

Run:

luacheck  %LOCALAPPDATA%/Luacheck/.luacheckrc

Get:

.luacheckrc:2:1: unused global variable 'allow_defined_top'

I guess allow_defined_top makes luacheck recognize all top-level defines as new globals instead of ignoring the ones already foudn in globals.

To solve this specific problem, I tried changing lua53\share\lua\5.3\luacheck\builtin_standards\init.lua:

builtin_standards.luacheckrc = {
   globals = { ...
   },
   allow_defined_top = false, -- this doesn't work
}

But no luck.

Workaround

Add to your .luacheckrc files:

-- Above allow_defined_top breaks std.luacheck
local luacheck = {
    std = 'luacheckrc',
    allow_defined_top  = false,
}
files['**/.luacheckrc'] = luacheck
