@spec bitmap_to_list(non_neg_integer(), non_neg_integer()) :: [String.t()]

Returns a list of "codepoints" (single-character strings) showing the base-2 value of value.

A minimum of padding elements are returned.

@spec debug_alphabet(String.t(), Dmp.Match.alpha()) :: [String.t()]

Formats the alphabet bitarray into a list of lines, showing binary values.

examples

Examples

iex> DebugUtils.debug_alphabet("aba", %{?a => 5, ?b => 2})
[
  "          alphabet: a b a",
  "    a            5: 1 0 1",
  "    b            2: 0 1 0"
]

@spec debug_rd(
  String.t(),
  String.t(),
  non_neg_integer(),
  Dmp.Match.bitap_array(),
  non_neg_integer(),
  integer()
) :: [String.t()]

Formats the rd bitarray into a list of lines, showing binary values.

• d - Error level for the bitarray.
• start - Lowest index that has been calculated.
• best_loc - Index in the text where the best match has been found.
