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

2550 -- enforce a canonical format for the use of
2551 -- blanks to separate source tokens.
2553 -- COMMENTS2 Check comments.
2554 -- COMMENTS Comments must meet the following set of rules:
2556 -- * The "--" that starts the column must either
2557 -- start in column one, or else at least one
2558 -- blank must precede this sequence.
2560 -- * Comments that follow other tokens on a line

2574 -- allows proper processing of the output

2578 -- For the purposes of this rule, a special

2580 -- ASCII ranges 16#21#..16#2F# or
2583 -- * A line consisting entirely of minus signs,

2600 -- COMMENTS1 Check comments (single space).
2601 -- Like COMMENTS2, but the -- of a comment only
2602 -- requires one or more spaces following, instead
2603 -- of two or more spaces.
2605 -- DOS_LINE_ENDINGS Check that no DOS line terminators are present
2606 -- All lines must be terminated by a single
2607 -- ASCII.LF character. In particular the DOS line
2608 -- terminator sequence CR / LF is not allowed).
2610 -- END Check end/exit labels.
2611 -- Optional labels on end statements ending
2612 -- subprograms and on exit statements exiting
2613 -- named loops, are required to be present.
2615 -- GNAT Enforces a set of style conventions that

2617 -- This maybe useful when developing code that
2618 -- is eventually intended to be incorporated into
2619 -- GNAT. For further details, see GNAT sources.
2621 -- HTABS No horizontal tabs.
2622 -- Horizontal tab characters are not permitted in
2623 -- the source text. Together with the BLANKS
2624 -- (no blanks at end of line) option, this
2625 -- enforces a canonical form for the use of blanks

2628 -- IF_THEN Check if-then layout.
2629 -- The keyword then must appear either on the
2630 -- same line as the corresponding if, or on a line
2631 -- on its own, lined up under the if with at least
2632 -- one non-blank line in between containing all or
2633 -- part of the condition to be tested.
2635 -- KEYWORD Check keyword casing.
2636 -- All keywords must be in lower case (with the
2637 -- exception of keywords such as digits used as
2638 -- attribute names to which this check does not
2641 -- LAYOUT Check layout.
2642 -- Layout of statement and declaration constructs
2643 -- must follow the recommendations in the Ada
2644 -- Reference Manual, as indicated by the form of
2645 -- the syntax rules. For example an else keyword
2646 -- must be lined up with the corresponding if
2649 -- There are two respects in which the style rule
2650 -- enforced by this check option are more liberal
2651 -- than those in the Ada Reference Manual.
2652 -- First in the case of record declarations,
2653 -- it is permissible to put the record keyword on
2654 -- the same line as the type keyword, and then
2655 -- the end in end record must line up under type.
2656 -- For example, either of the following two
2657 -- layouts is acceptable:
2670 -- Second, in the case of a block statement,
2671 -- a permitted alternative is to put the block
2672 -- label on the same line as the declare or begin
2673 -- keyword, and then line the end keyword up under
2674 -- the block label. For example both the following
2680 -- A : Integer := 3;
2687 -- A : Integer := 3;
2692 -- The same alternative format is allowed for
2693 -- loops. For example, both of the following are
2698 -- Clear : while J < 10 loop
2703 -- while J < 10 loop
2709 -- LINE_LENGTH Check maximum line length.
2710 -- The length of source lines must not exceed 79
2711 -- characters, including any trailing blanks
2712 -- The value of 79 allows convenient display on
2713 -- an 80 character wide device or window, allowing
2714 -- for possible special treatment of 80 character
2717 -- NONE Clear any previously set style checks.
2719 -- ORDERED_SUBPROGRAMS Check order of subprogram bodies.
2720 -- All subprogram bodies in a given scope (e.g.
2721 -- a package body) must be in alphabetical order.
2722 -- The ordering rule uses normal Ada rules for
2723 -- comparing strings, ignoring casing of letters,
2724 -- except that if there is a trailing numeric
2725 -- suffix, then the value of this suffix is used
2726 -- in the ordering (e.g. Junk2 comes before
2729 -- OVERRIDING_INDICATORS Check that overriding subprograms are
2730 -- explicitly marked as such. The declaration of
2731 -- a primitive operation of a type extension that
2732 -- overrides an inherited operation must carry
2733 -- an overriding indicator.
2735 -- PRAGMA Check pragma casing.
2736 -- Pragma names must be written in mixed case,
2737 -- that is, the initial letter and any letter
2738 -- following an underscore must be uppercase.
2739 -- All other letters must be lowercase.
2741 -- REFERENCES Check references.
2742 -- All identifier references must be cased in the
2743 -- same way as the corresponding declaration.
2744 -- No specific casing style is imposed on
2745 -- identifiers. The only requirement is for
2746 -- consistency of references with declarations.
2748 -- SPECS Check separate specs.
2749 -- Separate declarations ("specs") are required
2750 -- for subprograms (a body is not allowed to serve
2751 -- as its own declaration). The only exception is
2752 -- that parameterless library level procedures are
2753 -- not required to have a separate declaration.
2754 -- This exception covers the most frequent form of
2755 -- main program procedures.
2757 -- STANDARD_CASING Check casing of entities in Standard.
2758 -- Any identifier from Standard must be cased to
2759 -- match the presentation in the Ada Reference
2760 -- Manual (for example, Integer and ASCII.NUL).
2762 -- TOKEN Check token spacing.
2763 -- The following token spacing rules are enforced:
2765 -- * The keywords abs and not must be followed
2768 -- * The token => must be surrounded by spaces.
2770 -- * The token <> must be preceded by a space or
2771 -- a left parenthesis.
2773 -- * Binary operators other than ** must be
2774 -- surrounded by spaces. There is no
2775 -- restriction on the layout of the ** binary
2778 -- * Colon must be surrounded by spaces.
2780 -- * Colon-equal (assignment) must be surrounded
2783 -- * Comma must be the first non-blank character
2784 -- on the line, or be immediately preceded by
2785 -- a non-blank character, and must be followed
2788 -- * If the token preceding a left paren ends
2789 -- with a letter or digit, then a space must
2790 -- separate the two tokens.
2792 -- * A right parenthesis must either be the
2793 -- first non-blank character on a line, or it
2794 -- must be preceded by a non-blank character.
2796 -- * A semicolon must not be preceded by
2797 -- a space, and must not be followed by

3252 -- In addition to error messages, corresponding to illegalities as
3253 -- defined in the reference manual, the compiler detects two kinds of
3254 -- warning situations. First, the compiler considers some constructs
3255 -- suspicious and generates a warning message to alert you to a possible
3256 -- error. Second, if the compiler detects a situation that is sure to
3257 -- raise an exception at runtime, it generates a warning message.
3259 -- You may specify the following keywords to change this behavior:
3261 -- DEFAULT (D) The default behavior above.

3381 -- Suppress warnings for cases where parentheses
3382 -- are not used and the result is potential
3383 -- ambiguity from a reader's point of view.
3385 -- MODIFIED_UNREF Activates warnings for variables that are
3386 -- assigned (using an initialization value or with
3387 -- one or more assignment statements) but whose
3388 -- value is never read. The warning is suppressed
3389 -- for volatile variables and also for variables

3397 -- NORMAL Sets normal warning mode, in which enabled
3398 -- warnings are issued and treated as warnings
3399 -- rather than errors. This is the default mode.
3400 -- It can be used to cancel the effect of an
3401 -- explicit /WARNINGS=SUPPRESS or
3402 -- /WARNINGS=ERRORS. It also cancels the effect
3403 -- of the implicit /WARNINGS=ERRORS that is
3404 -- activated by the use of /STYLE=GNAT.
3406 -- OBSOLESCENT Activates warnings for calls to subprograms
3407 -- marked with pragma Obsolescent and for use of
3408 -- features in Annex J of the Ada Reference
3409 -- Manual. In the case of Annex J, not all
3410 -- features are flagged. In particular use of the
3411 -- renamed packages (like Text_IO), use of package
3412 -- ASCII and use of the attribute 'Constrained are

3482 -- UNUSED Activates warnings to be generated for entities
3483 -- that are defined but not referenced, and for
3484 -- units that are with'ed and not referenced. In
3485 -- the case of packages, a warning is also
3486 -- generated if no entities in the package are
3487 -- referenced. This means that if the package
3488 -- is referenced but the only references are in
3489 -- use clauses or renames declarations, a warning
3490 -- is still generated. A warning is also generated
3491 -- for a generic package that is with'ed but never
3492 -- instantiated. In the case where a package or
3493 -- subprogram body is compiled, and there is a
3494 -- with on the corresponding spec that is only
3495 -- referenced in the body, a warning is also
3496 -- generated, noting that the with can be moved
3497 -- to the body. The default is that such warnings

3500 -- NOUNUSED Suppress warnings for unused entities and
3503 -- VARIABLES_UNINITIALIZED Activates warnings on unassigned variables.
3504 -- Causes warnings to be generated when a variable
