| -- 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. |
| |
| -- Note: actual code is found in System.Case_Util, which is used internally |
| -- by the GNAT run time. Applications programs should always use this package |
| -- rather than using System.Case_Util directly. |
| |
| with System.Case_Util; |
| |
| package GNAT.Case_Util is |
| pragma Pure; |
| pragma Elaborate_Body; |
| -- The elaborate body is because we have a dummy body to deal with |
| -- bootstrap path problems (we used to have a real body, and now we don't |
| -- need it any more, but the bootstrap requires that we have a dummy body, |
| -- since otherwise the old body gets picked up. |
| |
| -- Note: all the following functions handle the full Latin-1 set |
| |
| function To_Upper (A : Character) return Character |
| renames System.Case_Util.To_Upper; |
| -- 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) |
| renames System.Case_Util.To_Upper; |
| -- Folds all characters of string A to upper case |
| |
| function To_Lower (A : Character) return Character |
| renames System.Case_Util.To_Lower; |
| -- 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) |
| renames System.Case_Util.To_Lower; |
| -- Folds all characters of string A to lower case |
| |
| procedure To_Mixed (A : in out String) |
| renames System.Case_Util.To_Mixed; |
| -- 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. |
