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 999999.
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;

2398 -- HTABS No horizontal tabs.
2399 -- Horizontal tab characters are not permitted in
2400 -- the source text. Together with the BLANKS
2401 -- (no blanks at end of line) option, this
2402 -- enforces a canonical form for the use of blanks

2405 -- IF_THEN Check if-then layout.
2406 -- The keyword then must appear either on the
2407 -- same line as the corresponding if, or on a line
2408 -- on its own, lined up under the if with at least
2409 -- one non-blank line in between containing all or
2410 -- part of the condition to be tested.
2412 -- KEYWORD Check keyword casing.
2413 -- All keywords must be in lower case (with the
2414 -- exception of keywords such as digits used as
2415 -- attribute names to which this check does not
2418 -- LAYOUT Check layout.
2419 -- Layout of statement and declaration constructs
2420 -- must follow the recommendations in the Ada
2421 -- Reference Manual, as indicated by the form of
2422 -- the syntax rules. For example an else keyword
2423 -- must be lined up with the corresponding if
2426 -- There are two respects in which the style rule
2427 -- enforced by this check option are more liberal
2428 -- than those in the Ada Reference Manual.
2429 -- First in the case of record declarations,
2430 -- it is permissible to put the record keyword on
2431 -- the same line as the type keyword, and then
2432 -- the end in end record must line up under type.
2433 -- For example, either of the following two
2434 -- layouts is acceptable:
2447 -- Second, in the case of a block statement,
2448 -- a permitted alternative is to put the block
2449 -- label on the same line as the declare or begin
2450 -- keyword, and then line the end keyword up under
2451 -- the block label. For example both the following
2457 -- A : Integer := 3;
2464 -- A : Integer := 3;
2469 -- The same alternative format is allowed for
2470 -- loops. For example, both of the following are
2475 -- Clear : while J < 10 loop
2480 -- while J < 10 loop
2486 -- LINE_LENGTH Check maximum line length.
2487 -- The length of source lines must not exceed 79
2488 -- characters, including any trailing blanks
2489 -- The value of 79 allows convenient display on
2490 -- an 80 character wide device or window, allowing
2491 -- for possible special treatment of 80 character
2494 -- NONE Clear any previously set style checks.
2496 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2497 -- All subprogram bodies in a given scope (e.g.
2498 -- a package body) must be in alphabetical order.
2499 -- The ordering rule uses normal Ada rules for
2500 -- comparing strings, ignoring casing of letters,
2501 -- except that if there is a trailing numeric
2502 -- suffix, then the value of this suffix is used
2503 -- in the ordering (e.g. Junk2 comes before
2506 -- OVERRIDING_INDICATORS Check that overriding subprograms are
2507 -- explicitly marked as such. The declaration of
2508 -- a primitive operation of a type extension that
2509 -- overrides an inherited operation must carry
2510 -- an overriding indicator.
2512 -- PRAGMA Check pragma casing.
2513 -- Pragma names must be written in mixed case,
2514 -- that is, the initial letter and any letter
2515 -- following an underscore must be uppercase.
2516 -- All other letters must be lowercase.
2518 -- REFERENCES Check references.
2519 -- All identifier references must be cased in the
2520 -- same way as the corresponding declaration.
2521 -- No specific casing style is imposed on
2522 -- identifiers. The only requirement is for
2523 -- consistency of references with declarations.
2525 -- SPECS Check separate specs.
2526 -- Separate declarations ("specs") are required
2527 -- for subprograms (a body is not allowed to serve
2528 -- as its own declaration). The only exception is
2529 -- that parameterless library level procedures are
2530 -- not required to have a separate declaration.
2531 -- This exception covers the most frequent form of
2532 -- main program procedures.
2534 -- STANDARD_CASING Check casing of entities in Standard.
2535 -- Any identifier from Standard must be cased to
2536 -- match the presentation in the Ada Reference
2537 -- Manual (for example, Integer and ASCII.NUL).
2539 -- TOKEN Check token spacing.
2540 -- The following token spacing rules are enforced:
2542 -- * The keywords abs and not must be followed
2545 -- * The token => must be surrounded by spaces.
2547 -- * The token <> must be preceded by a space or
2548 -- a left parenthesis.
2550 -- * Binary operators other than ** must be
2551 -- surrounded by spaces. There is no
2552 -- restriction on the layout of the ** binary
2555 -- * Colon must be surrounded by spaces.
2557 -- * Colon-equal (assignment) must be surrounded
2560 -- * Comma must be the first non-blank character
2561 -- on the line, or be immediately preceded by
2562 -- a non-blank character, and must be followed
2565 -- * If the token preceding a left paren ends
2566 -- with a letter or digit, then a space must
2567 -- separate the two tokens.
2569 -- * A right parenthesis must either be the
2570 -- first non-blank character on a line, or it
2571 -- must be preceded by a non-blank character.
2573 -- * A semicolon must not be preceded by
2574 -- a space, and must not be followed by
2575 -- a non-blank character.
2577 -- * A unary plus or minus may not be followed
2580 -- * A vertical bar must be surrounded by
2583 -- In the above rules, appearing in column one is

3277 -- Wide_Character. The hexadecimal digits may use upper

3287 -- NONE No wide characters are allowed. Same
3288 -- as /NOWIDE_CHARACTER_ENCODING.
3290 -- HEX In this encoding, a wide character is represented by
3291 -- the following five character sequence: ESC a b c d
3292 -- Where 'a', 'b', 'c', and 'd' are the four hexadecimal
3293 -- characters (using uppercase letters) of the wide
3294 -- character code. For example, ESC A345 is used to
3295 -- represent the wide character with code 16#A345#. This
3296 -- scheme is compatible with use of the full
3297 -- Wide_Character set.
3299 -- UPPER The wide character with encoding 16#abcd# where the
3300 -- upper bit is on (in other words, "a" is in the range
3301 -- 8-F) is represented as two bytes, 16#ab# and 16#cd#.
3302 -- The second byte may never be a format control
3303 -- character, but is not required to be in the upper
3304 -- half. This method can be also used for shift-JIS or
3305 -- EUC, where the internal coding matches the external

3329 -- half ASCII characters are represented as ASCII bytes
3330 -- and all upper half characters and other wide characters
