NAME

Pod::Elemental - work with nestable Pod elements

VERSION

version 0.103006

SYNOPSIS

  use Pod::Elemental;
  use Pod::Elemental::Transformer::Pod5;

  my $document = Pod::Elemental->read_file('lib/Pod/Elemental.pm');

  Pod::Elemental::Transformer::Pod5->new->transform_node($document);

  print $document->as_debug_string, "\n"; # quick overview of doc structure

  print $document->as_pod_string, "\n";   # reproduce the document in Pod

DESCRIPTION

Pod::Elemental is a system for treating a Pod (plain old documentation) documents as trees of elements. This model may be familiar from many other document systems, especially the HTML DOM. Pod::Elemental's document object model is much less sophisticated than the HTML DOM, but still makes a lot of document transformations easy.

In general, you'll want to read in a Pod document and then perform a number of prepackaged transformations on it. The most common of these will be the Pod5 transformation, which assumes that the basic meaning of Pod commands described in the Perl 5 documentation hold: =begin, =end, and =for commands mark regions of the document, leading whitespace marks a verbatim paragraph, and so on. The Pod5 transformer also eliminates the need to track elements representing vertical whitespace.

PERL VERSION

This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years.

Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.

ATTRIBUTES

event_reader

The event reader (by default a new instance of Pod::Eventual::Simple is used to convert input into an event stream. In general, it should provide read_* methods that behave like Pod::Eventual::Simple.

objectifier

The objectifier (by default a new Pod::Elemental::Objectifier) must provide an objectify_events method that converts Pod events into Pod::Elemental::Element objects.

document_class

This is the class for documents created by reading pod.

METHODS

read_handle

read_file

read_string

These methods read the given input and return a Pod::Elemental::Document.
