-package Csets is
-pragma Elaborate_Body (Csets);
-
- -- This package contains character tables for the various character
- -- sets that are supported for source representation. Character and
- -- string literals are not affected, only identifiers. For each set,
- -- the table in this package gives the mapping of letters to their
- -- upper case equivalent. Each table thus provides the information
- -- for building the table used to fold lower case to upper case, and
- -- also the table of flags showing which characters are allowed in
- -- identifiers.
-
- type Translate_Table is array (Character) of Character;
- -- Type used to describe translate tables
-
- type Char_Array_Flags is array (Character) of Boolean;
- -- Type used for character attribute arrays. Note that we deliberately
- -- do NOT pack this table, since we don't want the extra overhead of
- -- accessing a packed bit string.

- procedure Initialize;
- -- Routine to initialize following character tables, whose content depends
- -- on the character code being used to represent the source program. In
- -- particular, the use of the upper half of the 8-bit code set varies.
- -- The character set in use is specified by the value stored in
- -- Opt.Identifier_Character_Set, which has the following settings:
-
- -- '1' Latin-1
- -- '2' Latin-2
- -- '3' Latin-3
- -- '4' Latin-4
- -- '5' Latin-5 (Cyrillic ISO-8859-5)
- -- 'p' IBM PC (code page 437)
- -- '8' IBM PC (code page 850)
- -- 'f' Full upper set (all distinct)
- -- 'n' No upper characters (Ada/83 rules)
- -- 'w' Latin-1 plus wide characters also allowed
-
- function Is_Upper_Case_Letter (C : Character) return Boolean;
- pragma Inline (Is_Upper_Case_Letter);
- -- Determine if character is upper case letter
-
- function Is_Lower_Case_Letter (C : Character) return Boolean;
- pragma Inline (Is_Lower_Case_Letter);
- -- Determine if character is lower case letter
-
- Fold_Upper : Translate_Table;
- -- Table to fold lower case identifier letters to upper case
-
- Fold_Lower : Translate_Table;
- -- Table to fold upper case identifier letters to lower case
-
- Identifier_Char : Char_Array_Flags;
- -- This table has True entries for all characters that can legally appear
- -- in identifiers, including digits, the underline character, all letters
- -- including upper and lower case and extended letters (as controlled by
- -- the setting of Opt.Identifier_Character_Set, left bracket for brackets
- -- notation wide characters and also ESC if wide characters are permitted
- -- in identifiers using escape sequences starting with ESC.
