When used with GNAT, this file name will --- normally have an ads or adb suffix. - --- deffile is the full name of a text file containing definitions of --- symbols to be referenced by the preprocessor. This argument is --- optional. - --- The -c switch, causes both preprocessor lines and the lines deleted --- by preprocessing to be retained in the output source as comments marked --- with the special string "--! ". This option will result in line numbers --- being preserved in the output file. - --- The -b switch causes both preprocessor lines and the lines deleted by --- preprocessing to be replaced by blank lines in the output source file, --- thus preserving line numbers in the output file. - --- The -r switch causes a Source_Reference pragma to be generated that --- references the original input file, so that error messages will use --- the file name of this original file. - --- The -u switch causes gnatprep to treat any undefined symbol that it --- encounters as having the value False. Otherwise an undefined symbol --- is a fatal error. - --- The -s switch causes a sorted list of symbol names and values to be --- listed on the standard output file. - --- The -v switch causes a Copyright notice to be displayed, and --- lines containing errors in the input file or the definition file --- to be displayed before the errors. - --- The -D switch causes symbol 'symbol' to be associated with 'value'. --- This symbols can then be referenced by the preprocessor. Several --- -D switches may be specified. - --- Note: if neither -b nor -c is present, then preprocessor lines and --- deleted lines are completely removed from the output, unless -r is --- specified, in which case -b is assumed. - --- The definitions file contains lines of the form - --- symbol := value - --- where symbol is an identifier, following normal Ada (case-insensitive) --- rules for its syntax, and value is one of the following: - --- Empty, corresponding to a null substitution - --- A string literal using normal Ada syntax - --- Any sequence of characters from the set --- (letters, digits, period, underline) - --- Comment lines may also appear in the definitions file, starting with --- the usual --, and comments may be added to the definitions lines. - --- The input text may contain preprocessor conditional inclusion lines, --- and also general symbol substitution sequences. - --- The preprocessor conditional inclusion commands have the form - --- #if <expression> [then] --- lines --- #elsif <expression> [then] --- lines --- #elsif <expression> [then] --- lines --- ... --- #else --- lines --- #end if; --- --- Where expression is defined by the following grammar : --- expression ::= <symbol> --- expression ::= <symbol> = "<value>" --- expression ::= <symbol> = <symbol> --- expression ::= <symbol> 'Defined --- expression ::= not <expression> --- expression ::= <expression> and <expression> --- expression ::= <expression> or <expression> --- expression ::= <expression> and then <expression> --- expression ::= <expression> or else <expression> --- expression ::= ( <expression> ) - --- "or" and "and" may not be used in the same expression without --- using parentheses. - --- For these Boolean tests, the symbol must have either the value True or --- False. If the value is True, then the corresponding lines are included, --- and if the value is False, they are excluded. It is an error to --- reference a symbol not defined in the symbol definitions file, or --- to reference a symbol that has a value other than True or False. - --- The use of the not operator inverts the sense of this logical test, so --- that the lines are included only if the symbol is not defined. - --- The THEN keyword is optional as shown - --- Spaces or tabs may appear between the # and the keyword. The keywords --- and the symbols are case insensitive as in normal Ada code. Comments --- may be used on a preprocessor line, but other than that, no other --- tokens may appear on a preprocessor line. - --- Any number of #elsif clauses can be present, including none at all - --- The #else is optional, as in Ada - --- The # marking the start of a preprocessor line must be the first --- non-blank character on the line, i.e. it must be preceded only by --- spaces or horizontal tabs. - --- Symbol substitution is obtained by using the sequence - --- $symbol - --- anywhere within a source line, except in a comment. The identifier --- following the $ must match one of the symbols defined in the symbol --- definition file, and the result is to substitute the value of the --- symbol in place of $symbol in the output file. - -procedure GNATprep; |
