Nested Spacing Lint Utility

Create a tiny linting helper that checks spacing inside arrays and objects. Outer collections should use a single space of padding for primitive or mixed values, but when a collection directly wraps another array/object or a single-element array it should tighten spacing around that nested value to avoid double padding. The helper returns a concise report of spacing violations.

Capabilities

Enforces outer spacing

• Source like [1,2] reports a spacing violation on the outer brackets when padding is missing. @test

Allows nested exceptions

• Source like [{ a: 1 },[2]] passes when outer brackets brace tightly around nested arrays/objects or single-element arrays while still keeping spacing inside the nested structures themselves. @test

Returns a lint summary

• The lint helper returns an object containing errorCount and an ordered messages array with line and column numbers for each spacing issue. @test
