 Filter::cpp - cpp source filter


NAME

Filter::cpp - cpp source filter


SUPPORTED PLATFORMS

  • Linux
  • Solaris
  • Windows
This module is not included with the standard ActivePerl distribution. It is available as a separate download using PPM.

SYNOPSIS

    use Filter::cpp ;


DESCRIPTION

This source filter pipes the current source file through the C pre-processor (cpp) if it is available.

As with all source filters its scope is limited to the current source file only. Every file you want to be processed by the filter must have a

    use Filter::cpp ;

near the top.

Here is an example script which uses the filter:

    use Filter::cpp ;
    #define FRED 1
    $a = 2 + FRED ;
    print "a = $a\n" ;
    #ifdef FRED
    print "Hello FRED\n" ;
    #else
    print "Where is FRED\n" ;
    #endif

And here is what it will output:

    a = 3
    Hello FRED
