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

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

• s - The alphabet as returned by Dmp.Match.alphabet/1.
• pattern - The pattern that is associated with the alphabet.

examples

Examples

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

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

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

• rd - The bitarrary.
• text - The text associated with rd.
• pattern - The pattern associated with rd.
• d - The error level.
• start - The lowest index that has been calculated. Lines below this index will be marked with an asterisk.
• best_loc - The index in the text where the best match has been found. The line at this index will be marked with an "@"-sign.
