32--  Spelling checker
33
34--  This package provides a utility routine for checking for bad spellings
35--  for the case of Wide_String arguments.
36
37package GNAT.Wide_Spelling_Checker is
38   pragma Pure;
39
40   function Is_Bad_Spelling_Of
41     (Found  : Wide_String;
42      Expect : Wide_String) return Boolean;
43   --  Determines if the string Found is a plausible misspelling of the string
44   --  Expect. Returns True for an exact match or a probably misspelling, False
45   --  if no near match is detected. This routine is case sensitive, so the
46   --  caller should fold both strings to get a case insensitive match.
47   --
48   --  Note: the spec of this routine is deliberately rather vague. It is used
49   --  by GNAT itself to detect misspelled keywords and identifiers, and is
50   --  heuristically adjusted to be appropriate to this usage. It will work
51   --  well in any similar case of named entities.
