| -- 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 that all the routines in this package are available to the user |
| -- via GNAT.Case_Util, which imports all the entities from this package. |
| |
| package System.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. |
| |
