NAME

Filter::PPI - PPI based source filtering

SYNOPSIS

  package MyFilter;

  use Filter::PPI;

  sub ppi_filter {
    my ($class,$doc) = @_;

    # Do funny things to $doc here

    return $doc;
  }

  package MyModule;

  use MyFilter;

  # This will get filtered

DESCRIPTION

This module lets you write perl source filters using PPI to process the source. Compared to other modules used for writing source filters, it is quite simple. You only need to have one method in your class, called ppi_filter. This gets passed the class name, a PPI::Document object, and any arguments given to import. The method is expected to return a PPI::Document but not neccesarily the same one. The document returned will be what's used by perl to compile the program.
