Case is significant in the unix switch string. If a + -- unix switch string is preceded by the not sign (!) it means that the + -- effect of the corresponding command qualifier is to remove any previous + -- occurrence of the given switch in the command line. + + -- The DIRECTORIES_TRANSLATION format is used where a list of directories + -- is given. This possible corresponding formats recognized by GNATCmd are + -- as shown by the following example for the case of PATH + + -- PATH=direc + -- PATH=(direc,direc,direc,direc) + + -- When more than one directory is present for the DIRECTORIES case, then + -- multiple instances of the corresponding unix switch are generated, + -- with the file name being substituted for the occurrence of *. + + -- The FILE_TRANSLATION format is similar except that only a single + -- file is allowed, not a list of files, and only one unix switch is + -- generated as a result. + + -- the NO_SPACE_FILE_TRANSL is similar to FILE_TRANSLATION, except that + -- no space is inserted between the switch and the file name. + + -- The NUMERIC_TRANSLATION format is similar to the FILE_TRANSLATION case + -- except that the parameter is a decimal integer in the range 0 to 999999. + + -- For the OPTIONS_TRANSLATION case, GNATCmd similarly permits one or + -- more options to appear (although only in some cases does the use of + -- multiple options make logical sense). For example, taking the + -- case of ERRORS for GCC, the following are all allowed: + + -- /ERRORS=BRIEF + -- /ERRORS=(FULL,VERBOSE) + -- /ERRORS=(BRIEF IMMEDIATE) + + -- If no option is provided (e.g. just /ERRORS is written), then the + -- first option in the list is the default option. For /ERRORS this + -- is NORMAL, so /ERRORS with no option is equivalent to /ERRORS=NORMAL. + + -- The COMMANDS_TRANSLATION case is only used for gnatmake, to correspond + -- to the use of -cargs, -bargs and -largs (the ARGS string as indicated + -- is one of these three possibilities). The name given by COMMAND is the + -- corresponding command name to be used to interpret the switches to be + -- passed on. Switches of this type set modes, e.g. /COMPILER_QUALIFIERS + -- sets the mode so that all subsequent switches, up to another switch + -- with COMMANDS_TRANSLATION apply to the corresponding commands issued + -- by the make utility. For example + + -- /COMPILER_QUALIFIERS /LIST /BINDER_QUALIFIERS /MAIN + -- /COMPILER_QUALIFIERS /NOLIST /COMPILE_CHECKS=SYNTAX + + -- Clearly these switches must come at the end of the list of switches + -- since all subsequent switches apply to an issued command. + + -- For the DIRECT_TRANSLATION case, an implicit additional qualifier + -- declaration is created by prepending NO to the name of the qualifier, + -- and then inverting the sense of the UNIX_SWITCHES string. For example, + -- given the qualifier definition: + + -- "/LIST -gnatl" + + -- An implicit qualifier definition is created: + + -- "/NOLIST !-gnatl" + + -- In the case where, a ! is already present, inverting the sense of the + -- switch means removing it. + + subtype S is String; + -- A synonym to shorten the table + + type String_Ptr is access constant String; + -- String pointer type used throughout + + type Switches is array (Natural range <>) of String_Ptr; + -- Type used for array of switches + + type Switches_Ptr is access constant Switches; + + ---------------------------- + -- Switches for GNAT BIND -- + ---------------------------- + + S_Bind_Add : aliased constant S := "/ADD_PROJECT_SEARCH_DIR=*" & + "-aP*"; + -- /ADD_PROJECT_SEARCH_PATH=(directory[,...]) + -- + -- Add directories to the project search path. + + S_Bind_ALI : aliased constant S := "/ALI_LIST " & + "-A"; + -- /NOALI_LIST (D) + -- /ALI_LIST + -- + -- Output full names of all the ALI files in the partition.

For example an else keyword + -- must be lined up with the corresponding if + -- keyword. + -- + -- There are two respects in which the style rule + -- enforced by this check option are more liberal + -- than those in the Ada Reference Manual. + -- First in the case of record declarations, + -- it is permissible to put the record keyword on + -- the same line as the type keyword, and then + -- the end in end record must line up under type. + -- For example, either of the following two + -- layouts is acceptable: + -- + -- type q is record + -- a : integer; + -- b : integer; + -- end record; + -- + -- type q is + -- record + -- a : integer; + -- b : integer; + -- end record; + -- + -- Second, in the case of a block statement, + -- a permitted alternative is to put the block + -- label on the same line as the declare or begin + -- keyword, and then line the end keyword up under + -- the block label.

For example, both of the following are + -- permitted: + -- + -- + -- + -- Clear : while J < 10 loop + -- A (J) := 0; + -- end loop Clear; + -- + -- Clear : + -- while J < 10 loop + -- A (J) := 0; + -- end loop Clear; + -- + -- + -- + -- LINE_LENGTH Check maximum line length. + -- The length of source lines must not exceed 79 + -- characters, including any trailing blanks + -- The value of 79 allows convenient display on + -- an 80 character wide device or window, allowing + -- for possible special treatment of 80 character + -- lines. + -- + -- NONE Clear any previously set style checks. + -- + -- ORDERED_SUBPROGRAMS Check order of subprogram bodies. + -- All subprogram bodies in a given scope (e.g. + -- a package body) must be in alphabetical order. + -- The ordering rule uses normal Ada rules for + -- comparing strings, ignoring casing of letters, + -- except that if there is a trailing numeric + -- suffix, then the value of this suffix is used + -- in the ordering (e.g. Junk2 comes before + -- Junk10). + -- + -- OVERRIDING_INDICATORS Check that overriding subprograms are + -- explicitly marked as such. The declaration of + -- a primitive operation of a type extension that + -- overrides an inherited operation must carry + -- an overriding indicator. + -- + -- PRAGMA Check pragma casing. + -- Pragma names must be written in mixed case, + -- that is, the initial letter and any letter + -- following an underscore must be uppercase. + -- All other letters must be lowercase. + -- + -- REFERENCES Check references. + -- All identifier references must be cased in the + -- same way as the corresponding declaration. + -- No specific casing style is imposed on + -- identifiers. The only requirement is for + -- consistency of references with declarations. + -- + -- SPECS Check separate specs. + -- Separate declarations ("specs") are required + -- for subprograms (a body is not allowed to serve + -- as its own declaration). The only exception is + -- that parameterless library level procedures are + -- not required to have a separate declaration. + -- This exception covers the most frequent form of + -- main program procedures. + -- + -- STANDARD_CASING Check casing of entities in Standard. + -- Any identifier from Standard must be cased to + -- match the presentation in the Ada Reference + -- Manual (for example, Integer and ASCII.NUL). + -- + -- TOKEN Check token spacing. + -- The following token spacing rules are enforced: + -- + -- * The keywords abs and not must be followed + -- by a space. + -- + -- * The token => must be surrounded by spaces. + -- + -- * The token <> must be preceded by a space or + -- a left parenthesis. + -- + -- * Binary operators other than ** must be + -- surrounded by spaces.

Note that the combination UNUSED + -- followed by NOUNREFERENCED_FORMALS has the + -- effect of warning on unreferenced entities + -- other than subprogram formals. + -- + -- UNUSED Activates warnings to be generated for entities + -- that are defined but not referenced, and for + -- units that are with'ed and not referenced. In + -- the case of packages, a warning is also + -- generated if no entities in the package are + -- referenced. This means that if the package + -- is referenced but the only references are in + -- use clauses or renames declarations, a warning + -- is still generated.

This method can be also used for shift-JIS or + -- EUC, where the internal coding matches the external + -- coding. + -- + -- SHIFT_JIS A wide character is represented by a two-character + -- sequence, 16#ab# and 16#cd#, with the restrictions + -- described for upper-half encoding as described above. + -- The internal character code is the corresponding JIS + -- character according to the standard algorithm for + -- Shift-JIS conversion. Only characters defined in the + -- JIS code set table can be used with this encoding + -- method. + -- + -- UTF8 A wide character is represented using + -- UCS Transformation Format 8 (UTF-8) as defined in Annex + -- R of ISO 10646-1/Am.2. Depending on the character + -- value, the representation is a one, two, or three byte + -- sequence: + -- + -- 16#0000#-16#007f#: 2#0xxxxxxx# + -- 16#0080#-16#07ff#: 2#110xxxxx# 2#10xxxxxx# + -- 16#0800#-16#ffff#: 2#1110xxxx# 2#10xxxxxx# 2#10xxxxxx# + -- + -- where the xxx bits correspond to the left-padded bits + -- of the 16-bit character value. Note that all lower + -- half ASCII characters are represented as ASCII bytes + -- and all upper half characters and other wide characters + -- are represented as sequences of upper-half (The full + -- UTF-8 scheme allows for encoding 31-bit characters as + -- 6-byte sequences, but in this implementation, all UTF-8 + -- sequences of four or more bytes length will be treated + -- as illegal). + -- + -- EUC A wide character is represented by a two-character + -- sequence 16#ab# and 16#cd#, with both characters being + -- in the upper half. The internal character code is the + -- corresponding JIS character according to the EUC + -- encoding algorithm. Only characters defined in the JIS + -- code set table can be used with this encoding method. + + S_GCC_WideX : aliased constant S := "/NOWIDE_CHARACTER_ENCODING " & + "-gnatWn"; + -- NODOC (see /WIDE_CHARACTER_ENCODING) + + S_GCC_Xdebug : aliased constant S := "/XDEBUG " & + "-gnatD"; + -- /NOXDEBUG (D) + -- /XDEBUG + -- + -- Output expanded source files for source level debugging. + -- The expanded source (see /EXPAND_SOURCE) is written to files + -- with names formed by appending "_DG" to the input file name, + -- The debugging information generated by the /DEBUG qualifier will then + -- refer to the generated file.
