NAME

       shortc - generate short preprocessor definitions for long C identifiers

SYNOPSIS

       shortc [ -symlen ] [ -p ] [ -s ] file ...

DESCRIPTION

       Shortc  searches for instances of long identifiers in the specified files.  In its normal mode of operation shortc generates a list of pre-
       processor definitions that are unique in their first seven characters.

       The shortc output is then included into each file (or a common header file) which is processed using a flexnames version of cpp.

       If no files are given shortc reads from the standard input.

       The symlen argument may be used to change the default long identifier length from seven characters.

       The -s option generates a sed script instead of preprocessor definitions.  The -p option causes shortc to parse preprocessor lines.   These
       options are most useful together when flexnames support is not available from cpp.

BUGS

       When using cpp, preprocessor symbols must be weeded out by hand.  Otherwise they will cause (innocuous) redefinition messages.

       The -p option will incorrectly parse include file names which must be removed by hand from the output.

NAME

       cxref-cpp - A modified C preprocessor to use with cxref.

SYNOPSIS

       cxref-cpp ...

DESCRIPTION

       To  improve  the  output  that  is available for the source code for cross-referencing a modified version of the GNU CPP v2.7.2 is supplied
       (named cxref-cpp).

       This modified C preprocessor allows for a finer control over some features of the preprocessing that are not important for a compiler.	In
       a  standard  preprocessor, the preprocessor directives are intended for use only by the preprocessor, so passing the information through is
       not important.

       With cxref-cpp, there are some features that are different to the standard GNU CPP:

	      Compared to gcc versions earlier than version 2.8.0 there is an extra option that will output the #include  lines  from  the  source
	      file.  In version 2.8.0 and later this option is present.

	      Comments	trailing  a  #include  or  a  #define are not preserved by all versions of gcc even if the -C option is used.  This is not
	      important while compiling, but is useful for documenting.

	      The cxref-cpp program will take on the personality of the installed version of gcc so that the gcc header files can be parsed.  This
	      means  that it includes the same default include directory paths and macro definitions.  The file that contains these definitions is
	      called cxref-cpp.defines and is installed by the cxref-cpp-configure program or specified by  the  -cxref-cpp-defines  command  line
	      option.

OPTIONS

       The same as for gcc, apart from '-cxref-cpp-defines' described above.
