--  Simple casing functions

--  This package provides simple casing functions that do not require the
--  overhead of the full casing tables found in Ada.Characters.Handling.

package GNAT.Case_Util is
pragma Pure (Case_Util);

   --  Note: all the following functions handle the full Latin-1 set

   function To_Upper (A : Character) return Character;
   --  Converts A to upper case if it is a lower case letter, otherwise
   --  returns the input argument unchanged.

   procedure To_Upper (A : in out String);
   --  Folds all characters of string A to upper csae

   function To_Lower (A : Character) return Character;
   --  Converts A to lower case if it is an upper case letter, otherwise
   --  returns the input argument unchanged.

   procedure To_Lower (A : in out String);
   --  Folds all characters of string A to lower case

   procedure To_Mixed (A : in out String);
   --  Converts A to mixed case (i.e. lower case, except for initial
   --  character and any character after an underscore, which are
   --  converted to upper case.

end GNAT.Case_Util;
