NAME

C::Blocks::Filter - base package for writing filters for C::Blocks

SYNOPSIS

 # If you want to print out the code as it is sent
 # to the C compiler:
 
 use strict;
 use warnings;
 use C::Blocks;
 use C::Blocks::Filter;
 
 cblock {
     ... /* this code will be printed */
 }
 
 
 # If you want to write your own filter
 
 package My::Filter;
 use C::Blocks::Filter ();
 our @ISA = qw(C::Blocks::Filter);
 
 sub c_blocks_filter {
     # Modify $_ directly. Allow a new 'keyword'
     # called 'loop':
     s/loop/for/g;
 }
 
 # Then in another bit of code using this:
 use strict;
 use warnings;
 use C::Blocks;
 use My::Filter;
 
 cblock {
     int i;
     for (i = 0; i < 10; i++) {
         printf("i = %d\n", i);
     }
     loop (i = 0; i < 10; i++) {
         printf("i = %d\n", i);
     }
 }
