Instance Method Details

#cmp_nils(a, b) ⇒ Object

compares a and b based entirely on whether one or the other is nil arguments are in the same order as ‘a <=> b` nil is sorted earlier - so cmp_nils(nil, 1) => -1

If neither are nil, rather than returning ‘a <=> b` which would seem like the obvious shortcut, `nil` is returned. This allows us to distinguish between cmp_nils returning 0 for a comparison of filenames, which means “a comparison on the lines is meaningless - you cannot have a line number for a nil file - so they should be sorted the same”, and a <=> b returning 0, which means “the files are the same, so compare on the lines”

Returns:

  • 0, 1, -1, or nil
