--  Spelling checker

--  This package provides a utility routine for checking for bad spellings

package GNAT.Spelling_Checker is
pragma Pure (Spelling_Checker);

   function Is_Bad_Spelling_Of
     (Found  : String;
      Expect : String)
      return   Boolean;
   --  Determines if the string Found is a plausible misspelling of the
   --  string Expect. Returns True for an exact match or a probably
   --  misspelling, False if no near match is detected. This routine
   --  is case sensitive, so the caller should fold both strings to
   --  get a case insensitive match.
   --
   --  Note: the spec of this routine is deliberately rather vague. This
   --  routine is the one used by GNAT itself to detect misspelled keywords
   --  and identifiers, and is heuristically adjusted to be appropriate to
   --  this usage. It will work well in any similar case of named entities
   --  with relatively short mnemonic names.
