26 -- This package contains, for each of the command of the GNAT driver, one
27 -- constant array; each component of this array is a string that defines,
28 -- in coded form as explained below, the conversion of a VMS qualifier of the
29 -- command to the corresponding switch of the GNAT tool corresponding to the
32 -- This package is used by the GNAT driver to invokes the GNAT tools with the
33 -- switches corresponding to the VMS qualifier and by the Project Manager to
34 -- convert VMS qualifiers in project files to their corresponding switch
37 -- This package is also an input to the tool that generates the VMS GNAT
38 -- help information automatically.
40 -- NOTE: the format of this package must follow the following rules, so that
41 -- the VMS GNAT help tool works properly:
43 -- - Each command zone (where the eventual qualifiers are declared) must
44 -- begin with a boxed comment of the form:
46 -- ---------------------------------
47 -- -- Switches for GNAT <COMMAND> --
48 -- ---------------------------------
50 -- where <COMMAND> is the name of a GNAT command in capital letters, for
51 -- example BIND, COMPILE, XREF, ...
53 -- - each qualifier declaration must be followed either by
54 -- - a comment starting with "-- NODOC", to indicate that there is
55 -- no documentation for this qualifier, or
56 -- - a contiguous sequence of comments that constitute the
57 -- documentation of the qualifier.
59 -- - each command zone ends with the declaration of the constant array
60 -- for the command, of the form:
62 -- <Command>__Switches : aliased constant Switches :=
70 -- The syntax of a qualifier declaration is as follows:
72 -- SWITCH_STRING ::= "/ command-qualifier-name TRANSLATION"
76 -- | DIRECTORIES_TRANSLATION
78 -- | NO_SPACE_FILE_TRANSL
79 -- | NUMERIC_TRANSLATION
80 -- | STRING_TRANSLATION
81 -- | OPTIONS_TRANSLATION
82 -- | COMMANDS_TRANSLATION
83 -- | ALPHANUMPLUS_TRANSLATION
84 -- | OTHER_TRANSLATION
86 -- DIRECT_TRANSLATION ::= space UNIX_SWITCHES
87 -- DIRECTORIES_TRANSLATION ::= =* UNIX_SWITCH *
88 -- DIRECTORY_TRANSLATION ::= =% UNIX_SWITCH %
89 -- FILE_TRANSLATION ::= =@ UNIX_SWITCH @
90 -- NO_SPACE_FILE_TRANSL ::= =< UNIX_SWITCH >
91 -- NUMERIC_TRANSLATION ::= =# UNIX_SWITCH # | # number #
92 -- STRING_TRANSLATION ::= =" UNIX_SWITCH "
93 -- OPTIONS_TRANSLATION ::= =OPTION {space OPTION}
94 -- COMMANDS_TRANSLATION ::= =? ARGS space command-name
95 -- ALPHANUMPLUS_TRANSLATION ::= =| UNIX_SWITCH |
97 -- UNIX_SWITCHES ::= UNIX_SWITCH {, UNIX_SWITCH}
99 -- UNIX_SWITCH ::= unix-switch-string | !unix-switch-string | `string'
101 -- OPTION ::= option-name space UNIX_SWITCHES
103 -- ARGS ::= -cargs | -bargs | -largs
105 -- Here command-qual is the name of the switch recognized by the GNATCmd.
106 -- This is always given in upper case in the templates, although in the
107 -- actual commands, either upper or lower case is allowed.
109 -- The unix-switch-string always starts with a minus, and has no commas
110 -- or spaces in it. Case is significant in the unix switch string. If a
111 -- unix switch string is preceded by the not sign (!) it means that the
112 -- effect of the corresponding command qualifier is to remove any previous
113 -- occurrence of the given switch in the command line.
115 -- The DIRECTORIES_TRANSLATION format is used where a list of directories
116 -- is given. This possible corresponding formats recognized by GNATCmd are
117 -- as shown by the following example for the case of PATH
120 -- PATH=(direc,direc,direc,direc)
122 -- When more than one directory is present for the DIRECTORIES case, then
123 -- multiple instances of the corresponding unix switch are generated,
124 -- with the file name being substituted for the occurrence of *.
126 -- The FILE_TRANSLATION format is similar except that only a single
127 -- file is allowed, not a list of files, and only one unix switch is
128 -- generated as a result.
130 -- the NO_SPACE_FILE_TRANSL is similar to FILE_TRANSLATION, except that
131 -- no space is inserted between the switch and the file name.
133 -- The NUMERIC_TRANSLATION format is similar to the FILE_TRANSLATION case
134 -- except that the parameter is a decimal integer in the range 0 to 999.
136 -- For the OPTIONS_TRANSLATION case, GNATCmd similarly permits one or
137 -- more options to appear (although only in some cases does the use of
138 -- multiple options make logical sense). For example, taking the
139 -- case of ERRORS for GCC, the following are all allowed:
142 -- /ERRORS=(FULL,VERBOSE)
143 -- /ERRORS=(BRIEF IMMEDIATE)
145 -- If no option is provided (e.g. just /ERRORS is written), then the
146 -- first option in the list is the default option. For /ERRORS this
147 -- is NORMAL, so /ERRORS with no option is equivalent to /ERRORS=NORMAL.
149 -- The COMMANDS_TRANSLATION case is only used for gnatmake, to correspond
150 -- to the use of -cargs, -bargs and -largs (the ARGS string as indicated
151 -- is one of these three possibilities). The name given by COMMAND is the
152 -- corresponding command name to be used to interpret the switches to be
153 -- passed on. Switches of this type set modes, e.g. /COMPILER_QUALIFIERS
154 -- sets the mode so that all subsequent switches, up to another switch
155 -- with COMMANDS_TRANSLATION apply to the corresponding commands issued
156 -- by the make utility. For example
158 -- /COMPILER_QUALIFIERS /LIST /BINDER_QUALIFIERS /MAIN
159 -- /COMPILER_QUALIFIERS /NOLIST /COMPILE_CHECKS=SYNTAX
161 -- Clearly these switches must come at the end of the list of switches
162 -- since all subsequent switches apply to an issued command.
164 -- For the DIRECT_TRANSLATION case, an implicit additional qualifier
165 -- declaration is created by prepending NO to the name of the qualifier,
166 -- and then inverting the sense of the UNIX_SWITCHES string. For example,
167 -- given the qualifier definition:
171 -- An implicit qualifier definition is created:
175 -- In the case where, a ! is already present, inverting the sense of the
176 -- switch means removing it.
179 -- A synonym to shorten the table
181 type String_Ptr is access constant String;
182 -- String pointer type used throughout
184 type Switches is array (Natural range <>) of String_Ptr;
185 -- Type used for array of switches
187 type Switches_Ptr is access constant Switches;

1645 -- PC850 This code page (850) is a modification of 437 extended

2392 -- on its own, lined up under the if with at least
2393 -- one non-blank line in between containing all or
2394 -- part of the condition to be tested.
2396 -- KEYWORD Check keyword casing.
2397 -- All keywords must be in lower case (with the
2398 -- exception of keywords such as digits used as
2399 -- attribute names to which this check does not
2402 -- LAYOUT Check layout.
2403 -- Layout of statement and declaration constructs
2404 -- must follow the recommendations in the Ada
2405 -- Reference Manual, as indicated by the form of
2406 -- the syntax rules. For example an else keyword
2407 -- must be lined up with the corresponding if
2410 -- There are two respects in which the style rule
2411 -- enforced by this check option are more liberal
2412 -- than those in the Ada Reference Manual.
2413 -- First in the case of record declarations,
2414 -- it is permissible to put the record keyword on
2415 -- the same line as the type keyword, and then
2416 -- the end in end record must line up under type.
2417 -- For example, either of the following two
2418 -- layouts is acceptable:
2431 -- Second, in the case of a block statement,
2432 -- a permitted alternative is to put the block
2433 -- label on the same line as the declare or begin
2434 -- keyword, and then line the end keyword up under
2435 -- the block label. For example both the following
2441 -- A : Integer := 3;
2448 -- A : Integer := 3;
2453 -- The same alternative format is allowed for
2454 -- loops. For example, both of the following are
2459 -- Clear : while J < 10 loop
2464 -- while J < 10 loop
2470 -- LINE_LENGTH Check maximum line length.
2471 -- The length of source lines must not exceed 79
2472 -- characters, including any trailing blanks
2473 -- The value of 79 allows convenient display on
2474 -- an 80 character wide device or window, allowing
2475 -- for possible special treatment of 80 character
2478 -- NONE Clear any previously set style checks.
2480 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2481 -- All subprogram bodies in a given scope (e.g.
2482 -- a package body) must be in alphabetical order.
2483 -- The ordering rule uses normal Ada rules for
2484 -- comparing strings, ignoring casing of letters,
2485 -- except that if there is a trailing numeric
2486 -- suffix, then the value of this suffix is used
2487 -- in the ordering (e.g. Junk2 comes before
2490 -- OVERRIDING_INDICATORS Check that overriding subprograms are
2491 -- explicitly marked as such. The declaration of
2492 -- a primitive operation of a type extension that
2493 -- overrides an inherited operation must carry
2494 -- an overriding indicator.
2496 -- PRAGMA Check pragma casing.
2497 -- Pragma names must be written in mixed case,
2498 -- that is, the initial letter and any letter
2499 -- following an underscore must be uppercase.
2500 -- All other letters must be lowercase.
2502 -- REFERENCES Check references.
2503 -- All identifier references must be cased in the
2504 -- same way as the corresponding declaration.
2505 -- No specific casing style is imposed on
2506 -- identifiers. The only requirement is for
2507 -- consistency of references with declarations.
2509 -- SPECS Check separate specs.
2510 -- Separate declarations ("specs") are required
2511 -- for subprograms (a body is not allowed to serve
2512 -- as its own declaration). The only exception is
2513 -- that parameterless library level procedures are
2514 -- not required to have a separate declaration.
2515 -- This exception covers the most frequent form of
2516 -- main program procedures.
2518 -- STANDARD_CASING Check casing of entities in Standard.
2519 -- Any identifier from Standard must be cased to
2520 -- match the presentation in the Ada Reference
2521 -- Manual (for example, Integer and ASCII.NUL).
2523 -- TOKEN Check token spacing.
2524 -- The following token spacing rules are enforced:
2526 -- * The keywords abs and not must be followed
2529 -- * The token => must be surrounded by spaces.
2531 -- * The token <> must be preceded by a space or
2532 -- a left parenthesis.
2534 -- * Binary operators other than ** must be
2535 -- surrounded by spaces. There is no
2536 -- restriction on the layout of the ** binary
2539 -- * Colon must be surrounded by spaces.
2541 -- * Colon-equal (assignment) must be surrounded
2544 -- * Comma must be the first non-blank character
2545 -- on the line, or be immediately preceded by
2546 -- a non-blank character, and must be followed
2549 -- * If the token preceding a left paren ends
2550 -- with a letter or digit, then a space must
2551 -- separate the two tokens.
2553 -- * A right parenthesis must either be the
2554 -- first non-blank character on a line, or it
2555 -- must be preceded by a non-blank character.
2557 -- * A semicolon must not be preceded by
2558 -- a space, and must not be followed by
2559 -- a non-blank character.
2561 -- * A unary plus or minus may not be followed
2564 -- * A vertical bar must be surrounded by
2567 -- In the above rules, appearing in column one is
2568 -- always permitted, that is, counts as meeting
2569 -- either a requirement for a required preceding
2570 -- space, or as meeting a requirement for no

3260 -- ('Pos value) of the character in type
3261 -- Wide_Character. The hexadecimal digits may use upper
3262 -- or lower case letters.
3264 -- This notation can also be used for upper half
3265 -- Character values using the format ["xx"] where XX is
3266 -- two hexadecimal digits representing the coding ('Pos
3267 -- value) of the character in type Character (or
3268 -- Wide_Character). The hexadecimal digits may use upper
3271 -- NONE No wide characters are allowed. Same
3272 -- as /NOWIDE_CHARACTER_ENCODING.
3274 -- HEX In this encoding, a wide character is represented by
3275 -- the following five character sequence: ESC a b c d
3276 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
3277 -- characters (using uppercase letters) of the wide
3278 -- character code. For example, ESC A345 is used to
3279 -- represent the wide character with code 16#A345#. This
3280 -- scheme is compatible with use of the full
3281 -- Wide_Character set.
3283 -- UPPER The wide character with encoding 16#abcd# where the
3284 -- upper bit is on (in other words, "a" is in the range
3285 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
3286 -- The second byte may never be a format control
3287 -- character, but is not required to be in the upper
3288 -- half. This method can be also used for shift-JIS or
3289 -- EUC, where the internal coding matches the external
3292 -- SHIFT_JIS A wide character is represented by a two-character

3296 -- character according to the standard algorithm for
3297 -- Shift-JIS conversion. Only characters defined in the

3301 -- UTF8 A wide character is represented using
3302 -- UCS Transformation Format 8 (UTF-8) as defined in Annex
3303 -- R of ISO 10646-1/Am.2. Depending on the character

3311 -- where the xxx bits correspond to the left-padded bits
3312 -- of the 16-bit character value. Note that all lower
3313 -- half ASCII characters are represented as ASCII bytes
3314 -- and all upper half characters and other wide characters
3315 -- are represented as sequences of upper-half (The full
3316 -- UTF-8 scheme allows for encoding 31-bit characters as
3317 -- 6-byte sequences, but in this implementation, all UTF-8

3321 -- EUC A wide character is represented by a two-character
